Producer price and price transmission in a deregulated Ethiopian coffee market
Provedor de dados: 31
Autores: Worako,   Tadesse Kumma; van Schalkwyk,   Herman D.; Alemu,   Zerihun Gudeta; Ayele,   Gezahegn.
Coffee producers in Ethiopia have historically received a very small share of the export price of green coffee. Reasons that are often mentioned are heavy government intervention and high marketing and processing costs. Prior to 1992, government regulation of the domestic coffee market in the form of fixed producer prices and the monopoly power of the Ethiopian Coffee Marketing Corporation put a substantial wedge between the producer price and the world price of coffee by imposing an implicit tax on producers. The domestic coffee marketing system in Ethiopia was liberalised after 1992, which was envisaged to have a positive effect on producer prices and price transmission signals from world markets to producers. This paper, with the help of Cointegration...

TRANSMISSÃO DE PREÇOS DA SOJA ENTRE OS MERCADOS EXTERNO E INTERNO: UMA ABORDAGEM PARA A REGIÃO DE MARINGÁ.
Provedor de dados: 31
Autores: Tonin,   Julyerme Matheus; Barczsz,   Silvio Silvestre.
Esse artigo buscou analisar a relação de preços entre o mercado interno, especificamente a região de Maringá e o mercado externo da soja no período de julho de 1994 a dezembro de 2007. A teoria que embasa o trabalho é a Lei do Preço Único. Em se tratando de preços nos mercados interno e externo, deve-se verificar se tais preços são altamente relacionados, o que significa que são bons indicadores e podem ser considerados como referências seguras na tomada de decisão dos agentes, além de observar sua causalidade e sentido. Para tanto, foram realizados os testes de estacionariedade, causalidade de Granger e de co-integração. O teste de Granger sugere que há relação bidirecional entre as séries de preço analisadas, observou-se também a existência de uma...

Trade and Development When Exports Lack Diversification: A Case Study From Malawi
Provedor de dados: 31
Autores: Persaud,   Suresh Chand; Meade,   Birgit Gisela Saager.
Developing countries, particularly those that depend heavily on a small number of agricultural exports, are vulnerable to domestic and international shocks. These countries often have difficulty achieving sustained economic growth. This analysis uses Malawi, a country that earns most of its foreign exchange from tobacco, as a case study of export concentration and heavy exposure to volatility. The econometric results suggest that the decline in Malawi’s gross domestic product (GDP) when tobacco exports are falling is almost three times greater than the increase in GDP when exports are rising. Model-based simulations indicate that variability in tobacco exports leads to slower economic growth because GDP falls by a relatively large amount in response to a...

Price transmission in the Hungarian vegetable sector
Provedor de dados: 31
Autores: Bakucs,   Lajos Zoltan; Ferto,   Imre; Szabo,   Gabor G.
In this paper we analyse price transmission for the carrot, parsley, tomato, green pepper and potato markets. Although there is a dual farm structure dominated by small individual farms, our results imply that price information flows from the producer to the retail level for potatoes, parsley and carrots. Our results also suggest that farmers do not merely accept prices, but can actually influence market prices. Tomato and green pepper prices have large transmission elasticities, and causality runs from the retail to producer level. It therefore follows that tomato and green pepper producers tend to accept prices and that the sector’s prices are determined by upper market levels (processors, wholesalers, retailers). These results are reinforced by the fact...

Retail Dairy Prices Fluctuate with the Farm Value of Milk
Provedor de dados: 31
Autores: Stewart,   Hayden; Blayney,   Donald P.
Farm milk prices in the United States fluctuated throughout the 2000-2009 decade.  Dairy farmers, industry pundits, and policymakers all reacted with much alarm.  One point of concern has been the response of retail prices to farm price volatility.  This study investigates farm-to-retail price transmission for two major dairy products – whole milk and Cheddar cheese – in the 2000s.  Results show that price shocks at the farm gate were transmitted asymmetrically to retail.  However, in order to best identify the nature of the transmission process, it is important to fit alternative model specifications.

The Impact of the New York State Retail Milk Price Regulation  on Farm-to-Retail Price Transmission and  Supermarket Pricing Strategies in Metropolitan Fluid Milk Markets
Provedor de dados: 31
Autores: Bolotova,   Yuliya; Novakovic,   Andrew M.
The New York State Milk Price Gouging Law establishes that the retail prices of fluid milk products are not to exceed 200% of the prices that NYS milk processors pay for Class I milk. The enforcement of this law significantly affected the nature of the Class I fluid milk price transmission process and the milk pricing strategies of supermarkets in the five largest cities in New York State: New York City, Albany, Syracuse, Buffalo and Rochester.   During the pre-law period, supermarkets used a retail price-stabilization strategy, as evidenced by asymmetric Class I fluid milk price transmission. In contrast, supermarkets use a retail profit stabilization strategy during the law period.   This variation of retail milk price control actually creates an...

Trade Elasticities: The Significance of Trade Barriers, Multinationals and Market Structure
Provedor de dados: 31
Autores: Ahmadi-Esfahani,   Fredoun Z.; Anderson,   Glenn Michael.
The elasticity of price transmission measures the extent to which a change in world prices will be transmitted to an importing country, with an elasticity of less than one being attributed to trade barriers. Recent research highlights the role that multinational trading companies may play in impeding price transmission. Further, in markets characterised by monopolistic competition an estimate of the partial elasticity of demand may be of limited practical value if no account is taken of the reaction of competitors. In this paper the potential for market structure to affect price transmission and trade elasticities is demonstrated. The elasticity of price transmission has been central to a revised approach to estimation of trade elasticities and has been...

The relationship between spatial price transmission and geographical distance: the case of Brazil
Provedor de dados: 31
Autores: Hernandez-Villafuerte,   Karla Vanessa.
The objectives of this research are to investigate the influence of geographical distance on the cointegration relationship in order to increase knowledge on the issue, and to indentify its role in Brazilian agricultural markets. With this intention, the cointegration framework is applied allowing for the presence of multiple structural breaks in the long run equation. The inclusion of breaks is in response to the multiple changes of the agricultural system during the period of investigation. The spatial integration is calculated between each market pair. The cointegration coefficient and geographical distance relationship is calculated by means of an OLS regression, taking into account the quality of roads and the proximity to a border or port. The effect...

Price transmission in the Spanish bovine sector: the BSE effect
Provedor de dados: 31
Autores: Hassouneh,   Islam; Serra,   Teresa; Gil,   Jose Maria.
A regime-switching vector error correction model is applied to monthly price data to assess the impact of BSE outbreaks on price relationships and patterns of transmission among farm and retail markets for bovine in Spain. To evaluate the degree to which price transmission is affected by BSE food scares, a BSE food scare index is developed and used to determine regime-switching. Results suggest that BSE scares affect beef producers and retailers differently. Consumer prices are found to be weakly exogenous and not found to react to BSE scares, while producer prices conversely adjusted. The magnitude of the adjustment is found to depend on the magnitude of the BSE scare.

RELATIONSHIP BETWEEN SPATIAL PRICE TRANSMISSION AND GEOGRAPHICAL DISTANCE IN BRAZIL
Provedor de dados: 31
Autores: Hernandez-Villafuerte,   Karla Vanessa.
The price transmission between markets is often interpreted as providing insights into the market’s infrastructure efficiency and transaction costs. Thus, finding a possible explanation for the degree of integration has become an issue of special interest. Recent researchers have pointed out the distance between markets as one of the possible factors. However, the distance is closely related with other elements, such as road quality and the proximity to an export point, which affect transport costs, opportunity costs and thus the integration. Therefore, what the most important factor is when determining the relationship among markets remains unclear. The cointegration framework, OLS and principal component regressions are applied in order to investigate...

Price Transmission Asymmetries in the Spanish Lamb Sector
Provedor de dados: 31
Autores: Ben Kaabia,   Monia; Gil,   Jose Maria; Boshnjaku,   L.
The analysis of asymmetries in the price transmission mechanism at different levels of the marketing chain provides some interesting information about the degree of competition in vertical related markets. The objective of this paper is to investigate the non-linear adjustments of prices along the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a Threshold Autoregressive Model. Price relationships at farm, wholesale and retail levels are considered. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted to all prices in the system. In the shortrun, analyses suggest that the high degree of horizontal concentration among retailers allow...

Vertical price transmission between market operators in Hungarian agricultural product chains
Provedor de dados: 31
Autores: Varga,   Tibor.
Price transmission studies related to the cointegration of price time series are a suitable means for studying market dominance at the various market levels in the food product chains. For this study a price transmission asymmetry study was carried out for 18 commercial food product chains. In this study a monthly price time series was used for the period 2001 to 2005. It was found that there is significant product variation in market dominance which spans the entire industry. However, the variation is not significantly linked to either sectors or vertical levels. At times it is unstable and can easily tilt toward the vertical partner level. Depending on price changes, it can also vary, which, in turn, reflects changes in weather conditions. Following a...

TESTING FOR SYMMETRY IN PRICE TRANSMISSION: AN EXTENSION OF THE SHILLER LAG STRUCTURE WITH AN APPLICATION TO FRESH TOMATOES
Provedor de dados: 31
Autores: Parrott,   Scott D.; Eastwood,   David B.; Brooker,   John R.
An empirical model of the price relationship between distribution stages is developed based on the Shiller lag. The assumption of constant returns to scale is relaxed to incorporate changes in the volume of shipments. An iterative GLS methodology is developed to estimate the model. Tests for symmetry, length of adjustment, and the amount of price transmission are outlined. An application using the change in the retail price of tomatoes based on shipping point price changes is described. Results suggest that the supermarket chain does not respond differently to price increases versus decreases at the shipping point level.

Decomposing Changes in Agricultural Producer Prices
Provedor de dados: 31
Autores: Liefert,   William M.
This paper develops a method for decomposing changes in agricultural producer prices. The method builds on a procedure used by the World Bank, with the key variables in the decomposition being trade prices, exchange rates, and agricultural trade policies. The main ways by which we expand on the World Bank decomposition procedure are by broadening the analysis of policy effects, and by adding the effect from incomplete transmission of changes in border prices and exchange rates to producer prices, and the effect on prices from interactions between variables as they change simultaneously. We demonstrate the decomposition method by using the Russian poultry market in the late 1990s, and find that the dominant factor in changing the producer price was the...

Which Broiler Part is the Best Part?
Provedor de dados: 31
Autores: Goodwin,   Harold L., Jr.; McKenzie,   Andrew M.; Djunaidi,   Harjanto.
Predominance of production and marketing contracts in the broiler industry suggests a traditional analysis of price relationships might no longer be appropriate.  In this study, markets for broiler cuts are defined as spatial.  Results of a vector autoregressive regression analysis of monthly USDA data from 1987 to 2000 verify the price relationship between white meat and whole broiler prices.  Price shocks in the boneless skinless breast market have a greater effect than dark meat shocks, suggesting this market is most important in price transmission.  These results will assist industry participants to form more effective marketing and pricing strategies, thus adding efficiency to the market.

Autores: Zhang,   Xiaoyong; Qiu,   Huanguang; Huang,   Zhurong.
This study describes how governance mechanisms were formed that link small-scale apple farmers in China with export markets. These institutional innovations have improved the efficiency of price transmission and generated higher profit margins for various actors in the supply chain, in particular for small-scale farmers. Chinese apple exports are highly coordinated through ongoing long term loyal network relationships and vertical integration. Relevant policy implications and further challenges are discussed in the conclusion.

Price Transmission in Three Italian Food Chains: A Structural Break Approach
Provedor de dados: 31
Autores: Carraro,   Alessandro; Stefani,   Gianluca.
Recently a wide instability of food prices has been observed in world and European agricultural and food markets. Both media and policy makers have dealt with the unsatisfactory patterns of marketing margins and price transmission along the food chain which may bring about distributive issues and affect inflationary trends. Although price transmission and margins dynamics have attracted so much interest at the policy level, few Italian studies deal with this topic. Our aim is to provide a first analysis of the price transmission mechanism in three Italian agri-food chains (lamb, pork and pasta), within a structural change framework. Results show that structural breaks in the price transmission mechanism are an issue in the food chain of pasta and pork with...

Volatility in Agriculture Commodity Prices in India: Impact and Macroeconomic and Sector-Specific Policy Responses
Provedor de dados: 31
Autores: Bathla,   Seema.
Globalization and trade liberalization have exposed agricultural sector of many developing countries to sudden disturbances, caused not just by demand-supply conditions within their economies but also by volatility in global commodity prices, exchange rate and surge in imports. This paper evaluates the magnitude of sensitivity of Indian agriculture to these factors, and explores policy options that may neutralize their adverse effects, maintain price incentives and stability. The analysis is undertaken for one important tradable commodity viz. wheat by applying a structural econometric model, separately under the exportable and importable scenarios from 1980-81 to 2009-10. Findings reveal wheat to be increasingly driven by an incentive structure based on...

This article aims to evaluate the degree of competition in the dairy industry, in the relevant markets of Ultra High Temperature (UHT) milk and pasteurized milk, by means of price transmission and marketing margin behavior. The empirical analysis is based on the model formerly proposed by Houck (1977) and latter detailed by Carman and Sexton (2005).This model analyzes separately the effects of input price increases and reductions on consumer prices, allowing for estimations of price transmission and margin behavior. Cepea-USP and Fipe provide, respectively, weekly input prices and consumer prices, both for the period of December 1999 to December 2005. As a major result, the degree of competition in the UHT relevant market was found to be robustly different...

Grid Pricing: An Empirical Investigation of Market Signal Clarity
Provedor de dados: 31
Autores: Fausti,   Scott W.; Qasmi,   Bashir A.; Li,   Jing.
The ability of the grid marketing system for fed cattle to provide an efficient price transmission mechanism is investigated.  Nerlove’s (1958) adaptive expectations approach is adopted to model the relationship between grid premiums (discounts) and the weekly relative supply of carcass quality attributes. Linear regression techniques are used to estimate Nerlove’s supply response function. Granger Causality tests are conducted to investigate the relationship between grid premiums (discounts) and the relative supply of carcass quality attributes.  Regression estimates and the Granger Causality tests provide empirical support for the 2005 National Beef Quality Audit call for clearer market signals.

Movement Restrictions, Agricultural Trade and Price Transmission between Israel and the West Bank
Provedor de dados: 31
Autores: Rico,   Ihle; Rubin,   Ofir D.
Imposing military security measures as a consequence of violent conflict may lead to depressing economic effects for all parties involved. One implication is the limited ability to conduct trade, which in turn brings about welfare losses to the economic agents involved and may threat livelihoods and food security. This paper focuses on the consequences of the Israeli-Palestinian conflict, as a prominent example, on bilateral agricultural trade and price dynamics. For this purpose, we consider high-frequency wholesale price data and data on movement restrictions (complete closures) which were imposed by the Israeli Defense Forces in the West Bank between May 2007 and December 2008. In particular, we study the price dynamics of cucumbers and apples, two...

THE INFLUENCES OF EXPORT CONTROLS ON WHEAT MARKETS IN SERBIA DURING THE FOOD CRISIS 2007-2008
Provedor de dados: 31
Autores: Djuric,   Ivan; Glauben,   Thomas; Goetz,   Linde.
During the food crisis in 2007/2008 the government of Serbia restricted the export of wheat to ensure that wheat supply on the domestic market is sufficient thereby dampening the increase in consumer food prices. This study investigates the effects of the export restriction on the integration, equilibrium and stability of its domestic wheat market. Within the framework of a Markov-switching error correction model, we utilize weekly wheat grower prices of Serbia and world market prices and compare the state of the wheat market prevailing in the time period before the crisis to when the exports controls are effective. Our results suggest that although the degree of market integration and thus the long-run price elasticity do not change during the crisis, the...

Price transmission on the Hungarian milk market
Provedor de dados: 31
Autores: Bakucs,   Lajos Zoltan; Ferto,   Imre.
There has been little systematic analysis of the extent to which organic farming policies have influenced growth in the organic sector. Analyses of organic farming policy instruments, for the most part, provide extensive and detailed reviews of instruments applied either in a single country or across countries. Hence, there is a great need to examine systematically whether there is a relationship between the introduction of organic farming policies and the growth of the organic food sector, and whether particular designs of organic farming policies are more effective than others. In this paper, we take the first step in the endeavour of analysing the effects of organic farming by undertaking an econometric analysis of the relationship between organic...

The Impact of Avian Influenza on Vertical Price Transmission in the Egyptian Poultry Sector
Provedor de dados: 31
Autores: Hassouneh,   Islam; Radwan,   Amr; Serra,   Teresa; Gil,   Jose Maria.
In recent years, health risks have received increasing attention among consumers and created interest in analysing the relationship between food scares, food consumption and market prices. One of the most relevant and recent food scares is the avian influenza that has had important effects not only on human and animal health, but also on the economy. We assess effects of avian influenza on price transmission along the Egyptian poultry marketing chain. Although Egypt has been one of the most affected countries by avian influenza, this article is the first attempt to understand this food scare’s impacts on Egyptian poultry markets. In doing so, a multivariate smooth transition vector error correction model (STVECM) is applied to monthly poultry price data....

Global Market Shocks and Poverty in Vietnam: The Case of Rice
Provedor de dados: 31
Autores: Coxhead,   Ian A.; Linh,   Vu Hoang; Tam,   Le Dong.
World food prices have experienced dramatic increases in recent years. These “shocks” affect food importers and exporters alike. Vietnam is a major exporter of rice, and rice is also a key item in domestic production, employment and consumption. Accordingly, rice price shocks from the world market have general equilibrium impacts and as such, their implications for household welfare are not known ex ante. In this paper we first present a simple framework for understanding the direct and indirect welfare effects of a global market shock of this kind. Second, we quantify the transmission of the price shock from global indicator prices to domestic markets. Third, we then we use an applied general equilibrium (AGE) model to simulate the effects of domestic...

Marketing and pricing dynamics in the presence of structural breaks - the Hungarian pork market
Provedor de dados: 31
Autores: Bakucs,   Lajos Zoltan; Ferto,   Imre.
The study of marketing margins and price transmission on various commodity markets has been a popular research topic of the past decades (see MEYER, VON CRAMONTAUBADEL, 2004, for a recent survey), however with a few exceptions these studies focused on developed economies. In this paper we examine the above phenomena on the: Hungarian pork market. The Johansen (maximum likelihood) or Engle and Granger (two step) cointegration tests do not reject the no-cointegration null hypothesis between the Hungarian pork producer and retail price series. Therefore we apply the Gregory and Hansen procedure with recursively estimated breakpoints and ADF statistics, and found that the prices are cointegrated with a structural break occurring in April 1996. Exogeneity tests...

CAP REFORM, WHEAT PRICE INSTABILITY AND PRODUCER WELFARE
Provedor de dados: 31
Autores: Thompson,   Stanley R.; Gohout,   Wolfgang.
We use a simple nonlinear commodity market model to illustrate the impact of recent reforms of the CAP on the variability of EU and world wheat prices. Second, within an expected utility framework we estimate the transfer and risk effects on producer welfare due to market liberalizing reforms. We found that wheat producers were over-compensated for the losses due to lower prices following the 1992 reforms. The transfer effect clearly dominated while the risk component was small. Further, we did not find producer incomes to be more unstable following to the 1992 CAP reforms.

Using the Logistic Functional Form for Modelling International Price Transmission in Net Trade Simulation Models
Provedor de dados: 31
Autores: Banse,   Martin; Grethe,   Harald.
Various reasons including cif/fob spread, differing political price protection depending on the net trade situation, and domestic transportation cost contribute to situations in which domestic prices are different in an exporting compared to an importing situation. Net trade models that take these differences into account must somehow deal with the problem of products that are not exported at the export-based price, because it is too low, and are not imported at the import-based price, because it is too high. In such a case, the equilibrium price lies somewhere between the export- and the import-based price. This paper presents the application of the Logistic functional form for depicting price transmission from international to domestic prices in the net...

Autores: Cunha,   Denis Antonio da; Braga,   Marcelo Jose; Campos,   Antonio Carvalho; Fernandes,   Luciany Lima.
The robusta coffee market has experienced changes which are characterized by a growth in the demand and the confirmation of Vietnam as the world’s greater producer and exporter leaving behind traditional producers as Indonesia. These changes motivated the analysis of international price integration and the main markets of this commodity: Vietnam, Brazil, Indonesia and India. It was tested the hypothesis that Vietnam transmits prices shocks to the other markets. The framework used the analysis of co-integration and the Vector Error Correction (VEC) model. It was shown that, in the period from 1988 to 2005, the foreign price and the ones from Vietnam, Brazil and Indonesia were integrated and the India’s price was affected by factors that are not common to...

Analysis of economic issues relating to the dairy sector, with emphasis on price transmission

Autores: Popovics,   Peter Andras.
The dramatic decline in consumption after 1990 was an important problem during the analysis of the sector. Even today, consumption is still below the degree that was before the political change, and significantly lags behind the EU level. The importance of this topic is emphasized by the fact that surplus milk could be marketed through the increased domestic consumption; this would create a more stable and calculable situation for farmers. Therefore, I considered it important to reveal what factors and by what shares influence the consumption of milk and dairy products. The relationship, time series and cross-sectional analysis based on national and international databases demonstrate the relationship between the consumption of milk and dairy products and...

Volatile world market prices for dairy products - how do they affect domestic price formation: The German cheese market
Provedor de dados: 31
Autores: Weber,   Sascha A.; Salamon,   Petra; Hansen,   Heiko.
Since the stepwise reduction of intervention prices combined with watered down conditions and suspended export refunds, respectively, the EU dairy industry faces new challenges regarding wild price fluctuations originally caused in third countries. In the past, the EU domestic market was insulated as far as possible from world markets. However, today global prices could affect prices even at the level of consumers, but more directly at the level milk producers. Volatility noticeable increased with the price peak in 2007, followed by the drop in 2008, and a new price boost in 2010. Additionally, reduced security in marketing of butter and skimmed milk powder led to higher processing share of cheese which is not only exported but also increasingly consumed...

Provedor de dados: 31
Autores: Traub,   Lulama Ndibongo; Myers,   Robert J.; Jayne,   Thomas S.; Meyer,   Ferdinand H.
Price transmission between the South African market and other regional markets is not as straightforward, despite South Africa’s role of a surplus producer for the region. There appears to be a host of local factors that must be taken into account in order to anticipate the likely level of regional food prices. This article assesses the degree of market integration and the speed of price adjustment to spatial price differentials between the SAFEX maize price in South Africa and maize grain and maize meal prices in Maputo, Mozambique. The findings of this study indicate that under certain trading regimes, there is no evidence of a long-run relationship between Mozambican and South African maize grain prices. This implies that any large deviations, within...

Price Transmission and Marketing Margins in the Slovenian Beef and Pork Markets During Transition
Provedor de dados: 31
Autores: Bojnec,   Stefan.
As in many other transition countries processing and marketing margins are also larger in the Slovenian meat market than respective margins in market economies. In addition, margin of the Slovenian pork chain is greater than in the beef chain. Its decline in the pork market indicates an adjustment to more competitive markets. Co-integration models are applied to estimate vertical price transmission and to examine margins and degree of competition in the meat marketing chains. Results indicate the existence of a long run equilibrium regarding vertical price transmission in the beef and pork sectors. Both the farm-gate beef and pork prices are identified as weakly exogenous in the long run. The structural tests imposing a homogeneity restriction suggest a...

The nowadays development in agribusiness can be characterised as shifting of power to the finalising levels and distribution in food commodity chains, which influence as well as form competitive environment of farm and also food-processing companies. The dependence of producers (farmers) on finalising stage is increasing, as well as the risk is transferred and the marked power is enforced in food commodity chains. Those factors are changing proportions, conditions of approach and share of individual stages of commodity chain on value added launched in final product. Possible approach to the identification of market power within food commodity chains is the approach based on price transmission analysis; inelastic price transmission (especially in case of...

Spatial Price Transmission in Kazakh Wheat Markets
Provedor de dados: 31
Autores: Yakhshilikov,   Yorbol; Brosig,   Stephan.
Reliable marketing opportunities in both interregional and international trade are an important precondition for further development of the agricultural sector. In this study we assess interregional integration of Kazakh wheat markets. We apply asymmetric threshold error correction models to assess the co-movement of elevator prices at three grain-trading spots in the northern and central parts of the country. Results suggest that markets of two northern grain-trading spots (Petropavlovsk and Kokshetau) are closely connected with each other while their connection with Karaganda in central Kazakhstan is much weaker. Here, levelling out price gaps through arbitrage trade only occurs after a threshold of considerable extent has been surpassed.

Local Impacts of a Global Crisis - Food Price Transmission and Poverty Impacts in Ghana
Provedor de dados: 31
Autores: Cudjoe,   Godsway; Breisinger,   Clemens; Diao,   Xinshen.
This paper takes a local perspective on global food price shocks by analyzing food price transmission between regional markets in Ghana. It also assesses the impacts of food price increases on various household groups. Taking the recent global food crisis as an example, we find that prices for domestic staples are highly correlated with prices for imported rice. However, price transmission between pairs of domestic regional markets is limited; it is complete for local rice and maize only when more rigorous cointegration analysis is applied. Our findings also show the important role of seasonality in the determination of market integration and price transmission. The welfare effect for households as consumers appears relatively modest at the aggregate...

Asymetric Price Transmission in the Spanish Lamb Sector
Provedor de dados: 31
Autores: Ben Kaabia,   Monia; Gil,   Jose Maria.
This paper aims to investigate the non-linear adjustments of prices between farm and retail prices in the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a three-regime Threshold Autoregressive Model. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted along the marketing chain. In the short-run, price adjustments between the farm and the retail levels are asymmetric and are representative of a demand-pull transmission mechanism. On the other hand, retailers benefit from any shock, whether positive or negative, that affects supply or demand conditions.

NORTH AMERICAN AGRICULTURAL MARKET INTEGRATION AND ITS IMPACT ON THE FOOD AND FIBER SYSTEM
Provedor de dados: 31
Autores: Vollrath,   Thomas L.
Economic change and market dynamics have fundamentally altered the structure and performance of agricultural markets in the United States, Canada, and Mexico within the last 25 years. Many factors have helped shape the current North American food and fiber system, including technological change, domestic farm policies, international trade agreements, and the economic forces of supply and demand. Ratification of NAFTA, for example, helped integrate the North American market, sparking a surge in trade and investment among the United States, Canada, and Mexico. In recent years, efforts to further integrate the continental market seem to have slowed. Broadening the scope of NAFTA to include institutional reforms that lead to a more unified system of commercial...

The paper explores the characteristics of spatial price dynamics for fresh vegetables. The analysis is carried out on selected EU prices for tomatoes and cauliflowers collected on some of the main production and consumption markets. It is based on the estimation of an time-varying threshold autoregressive econometric specification that is shown capable to underline the asymmetries in inter-Countries price transmission. The model shows that that horizontal price transmissions among net producer and net consumer markets is asymmetric and how such characteristic differs for markets closer to production areas or to consumption locations. This paper allowed to assess the average elapsing time for shocks to be transmitted among spatially separated markets, and,...

We find that the assumptions regarding the nature of their regime-switching mechanisms are fundamentally different so that each model is suitable for a certain type of nonlinear price transmission. Furthermore, we conduct a Monte Carlo experiment in order to study the performance of the estimation techniques of both models for simulated data. We find that both models are adequate for studying price transmission since their characteristics match the underlying...

Autores: Wang,   Xiuqing; Weldegebriel,   Habtu T.; Rayner,   Anthony J.
In this paper, we aim to model the vertical relation between retailers and suppliers in the food industry whereby retailers exercise seller power in their relation with consumers and buyer power in their relation with producers. We then evaluate the degree of price transmission, relative to the perfectly competitive benchmark, from the farm to the retail sector assuming a supply shock. With the view to evaluating the impact of market power's interaction with industry technology on the degree of price transmission, we assume industry technology to be characterised by variable input proportions and non-constant returns to scale. Our model predicts that, relative to that which obtains when markets are perfectly competitive and industry technology is...

How Retail Beef and Bread Prices Respond to Changes in Ingredient and Input and Costs
Provedor de dados: 31
Autores: Roeger,   Edward; Leibtag,   Ephraim S.
The extent to which cost changes pass through a vertically organized production process depends on the value added by each producer in the chain as well as a number of other organizational and marketing factors at each stage of production. Using 36 years of monthly Bureau of Labor Statistics price indices data (1972-2008), we model pass-through behavior for beef and bread, two retail food items with different levels of processing. Both the farm-to-wholesale and wholesale-to-retail price responses are modeled to allow for the presence of structural breaks in the underlying long-term relationships between price series. Broad differences in price behavior are found not only between food categories (retail beef prices respond more to farm-price changes than do...

ASYMMETRIC PRICE RELATIONSHIPS IN THE U.S. BROILER INDUSTRY
Provedor de dados: 31
Autores: Bernard,   John C.; Willett,   Lois Schertz.
This study presents a testing methodology to analyze potential price asymmetries among the farm, wholesale, and retail levels of the U.S. broiler industry. Lag length, direction of causality and power of the integrators in the industry have allowed the wholesale price to become the center, causal price in the market. Asymmetric price transmissions, however, are limited. While downward movements in the wholesale price are passed on more fully to growers than increases in the wholesale price, only consumers in the North Central region of the U.S. share a larger portion of wholesalers' price increases than price decreases.

Cooperative vs. Non-Cooperative Spatial Competition for Milk in the Presence of Farm Marketing Cooperatives
Provedor de dados: 31
Autores: Graubner,   Marten; Koller,   Ines; Salhofer,   Klaus; Balmann,   Alfons.
Although important, the spatial dimension is often neglected in studies of market power and competition in agricultural markets. This paper investigates spatial competition for raw milk between dairies under the presence of marketing cooperatives. Since observed in reality, our model is based on uniform delivered pricing and overlapping market areas. We compare spatial cooperative price matching with non-cooperative Hotelling-Smithies conduct. Utilizing a vector error correction model we show that the observed low price transmission in Germany is in line with cooperative behaviour. This seems rational since it increases processors profits. The abolition of the quota system may increase price transmission.

Non-parametric and Parametric Modeling of Biodiesel - Sunflower Oil - Crude Oil Price Relationships
Provedor de dados: 31
Autores: Hassouneh,   Islam; Serra,   Teresa; Gil,   Jose Maria.
Multivariate local linear regression and parametric error correction models are applied to assess price linkages and price transmission patterns between food and energy prices in Spain. Weekly biodiesel, sunflower and crude oil prices observed from November 2006 to October 2010 are used in the empirical analysis. Results suggest the existence of a long-run equilibrium relationship between the three prices studied. Biodiesel is the only variable that adjusts to deviations from this long-run parity. Local linear regression techniques show that the speed of adjustment of biodiesel prices is higher when biodiesel is cheap than when it is expensive. Energy prices are also found to influence sunflower oil prices through the short-run price dynamics.

Have Recent Increases in International Cereal Prices Been Transmitted to Domestic Economies? The Experience in Seven Large Asian Countries
Provedor de dados: 31
Autores: Dawe,   David.
International cereal prices (in US dollar terms) have been increasing since 2003, but it is domestic prices that affect food consumption and production. This paper analyzes, for seven large Asian countries, the extent to which domestic prices have increased since 2003 and presents several conclusions. First, the data show that the increases in world cereal prices have been accompanied by a real depreciation of the US dollar. For many countries (but not all), this depreciation has neutralized a substantial proportion of the increase in world prices. Second, domestic commodity specific policies in several of these Asian countries have further stabilized domestic prices relative to the change in world prices. This has been especially true for rice, the main...

A nonlinear model of demand and costs, including firm specific and industry cost shift variables is estimated for each of the four leading supermarkets. Cost pass through rates for industry wide shifts are near 100%; for firm specific costs they range between 32 and 47 percent, suggesting that substantial differentiation and related market power. A test for focal point collusion finds that channel firms elevated retail prices when the Northeast Dairy Compact elevated and stabilized raw milk prices.

Autores: Varga,   Tibor; Tunyogine Nechay,   Veronika; Kemeny,   Gabor.
A termékpályák tagoltsága, a termékpálya-fázisok eltérő koncentráltságából fakadó piaci formák a tevékenységi láncban kialakult áralkukat, valamint az elérhet ő árnyereséget, illetve árveszteséget meghatározzák. A számítási eredményeket a piac szereplőinek véleményével ütköztető vizsgálataink megerősítik, hogy a termékek túlnyomó részénél az erőfölény a legkoncentráltabb oldalnál, a kereskedelmi fázisban található. A kiskereskedelmi láncok nem csak egyértelműen árvezetők, de egyben a feldolgozott termékek importárain keresztül az egész vertikum áralakulását meghatározzák. A termelői és feldolgozói fázis között – nagyon kevés kivétellel – az árnyereség a feldolgozóknál figyelhető meg. Az ágazati szintű erőfölény vizsgálataink szerint termékenként erősen...

Semiparametric Evidence on the Nature of Price Transmission in Tanzanian Maize Markets
Provedor de dados: 31
Autores: Ihle,   Rico; von Cramon-Taubadel,   Stephan.
Maize is a major staple food in Sub-Saharan Africa. Monthly maize prices in Tanzania are analyzed since the country is an important maize producer and exporter in East Africa. We analyze price transmission between the five most important urban regions of Tanzania between 2000 and 2008 which correspond to major maize production or consumption areas. We propose a novel method for the analysis. The semiparametric vector error-correction model allows the partial impact of the past deviations from price equilibria on current price changes to be potentially nonlinear. The nonparametric estimates of these partial influences suggest that they can be adequately modeled by linear functions.

In this paper we show how regime-switching vector error correction models can be used to assess the effects of food scares on price transmission along the food marketing chain. Our empirical implementation focuses on the impacts of the BSE crisis on price relationships and patterns of transmission among farm and retail markets for bovine in Spain. Monthly prices are used over the 1996-2005 period. A BSE food scare index is developed in order to measure the scale of the food scare crisis. Results suggest that the crisis affects beef producers and retailers differently. While consumer prices are not found to adjust to the crisis, producer prices do, though only when the scale of the food scare reaches certain minimum levels.

Consequences of BSE disease outbreaks in the Canadian beef industry
Provedor de dados: 31

This study examines farm to wholesale prices spreads to measure the impact of the BSE disease outbreak on the Canadian beef industry. The study uses structure break tests developed by Gregory and Hansen (1996) and Hansen (1992) examine possible breaks within co integrating relationships. The study finds evidence that the industry began realignment as a result of the UK BSE disease outbreak, and the Canadian BSE disease outbreak was simply the largest realignment of the process beginning with the UK disease outbreak. However, the only statistically significant break was the BSE disease outbreak itself in May 2003. Stability was not restored until the border was reopened in 2005. Specific results indicated that the processing sector exploited the border...
