Volatile world market prices for dairy products - how do they affect domestic price formation: The German cheese market AgEcon
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...

Measuring Integration and Efficiency in Maize Grain Markets: The Case of South Africa and Mozambique AgEcon
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 AgEcon
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...

Some approaches to the analysis of market structure's impact in milk commodity chain AgEcon
Novak, Petr.
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 AgEcon
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.

Estimation of impact of EU agricultural policies on the world market prices AgEcon
Chantreuil, Frederic; Tabeau, Andrzej A.; van Leeuwen, Myrna.
According to world market studies, the influence of policy measures on the world market price in one or in a limited number of countries is, in general, much less significant than the influence of multilateral policy changes. To investigate the impact of EU agricultural policies on world market prices, we attempt to model the transmission between EU policy and world prices directly via world market price equations, as part of the AGMEMOD model.

INTERREGIONAL INTEGRATION OF WHEAT MARKETS IN KAZAKHSTAN AgEcon
Brosig, Stephan; Yakhshilikov, Yorbol.
Reliable marketing opportunities in both interregional and international trade along with relatively low transportation [and transaction] costs are essential to profitability of wheat production. In this study we have investigated one aspect of the quality of marketing and trade opportunities in the Kazakh wheat sector, that is the extent and nature of integration among regional wheat markets. We applied threshold cointegration technique to assess the co-movement between time series of elevator prices at three grain-trading (and producing) 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...

Transmision de precios en los mercados regionales de ovino en Espana AgEcon
Boshnjaku, L.; Ben Kaabia, Monia; Gil, Jose Maria.
Resumen El análisis de las relaciones de precios existentes en un determinado sector permiten, por un lado, ofrecer una idea aproximada del funcionamiento de los mercados y, por otro, anticipar respuestas ante shocks inesperados en mercados relacionados. El objetivo de este estudio se ha centrado en el análisis de la transmisión de precios entre los principales mercados de ovino en España. Para llevar a cabo este estudio se ha adoptado un enfoque econométrico que ha tenido en cuenta las propiedades estocásticas de las series, la posible naturaleza multivariante de los procesos de transmisión, y la distinción entre el comportamiento a corto y largo plazo. Los resultados indican que los mercados de ovino se encuentran bastante interrelacionados pudiéndose...

Local Impacts of a Global Crisis - Food Price Transmission and Poverty Impacts in Ghana AgEcon
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 AgEcon
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 AgEcon
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...

Spatial price dynamics in the EU F&V sector: the cases of tomato and cauliflower AgEcon
Santeramo, Fabio G.; Cioffi, Antonio.
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,...

A Comparison of Threshold Cointegration and Markov-Switching Vector Error Correction Models in Price Transmission Analysis AgEcon
Ihle, Rico; von Cramon-Taubadel, Stephan.
We compare two regime-dependent econometric models for price transmission analysis, namely the threshold vector error correction model and Markov-switching vector error correction model. We first provide a detailed characterization of each of the models which is followed by a comprehensive comparison. 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...

Nonlinear Vector Error Correction Models in Price Transmission Analysis: Threshold Models vs. Markov-Switching Models AgEcon
Ihle, Rico; von Cramon-Taubadel, Stephan.
This work provides a comparison of methodologies for applied research in price transmission analysis. We compare two regime-dependent econometric models, namely the threshold vector error correction model and the Markov-switching vector error correction model. We first provide a conceptual comparison in which we find that the regime-switching mechanisms of the models differ fundamentally so that each model is suitable for a certain type of nonlinear price trans-mission. Furthermore, we conduct a Monte Carlo experiment in order to study the performance of each of the models’ estimation techniques for simulated data. Although each model possesses an immediate economic interpretation which well matches an aspect of the theory of price transmission, the...

Price Transmission, Market Power and Returns to Scale AgEcon
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 AgEcon
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 AgEcon
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.

Sino-U.S. Price Transmission in Agricultural Commodities: How Important are Exchange Rate Movements? AgEcon
Mutuc, Maria Erlinda M.; Pan, Suwen; Hudson, Darren.
Commodity price transmissions between China and the U.S. are examined. The results indicate that variations in Chinese cotton and soybean prices are transmitted to U.S. cotton and soybean prices while variations in Chinese wheat and rice prices do not get transmitted to U.S. wheat and rice prices. The effects of volatilities in oil prices and in the exchange rate on the price transmission are also assessed.
