Última Linking Small Scale Farmers in China with the International Markets: A Case of Apple Export Chains AgEcon 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.

Ano: 2009 URL: http://purl.umn.edu/53798 Price Transmission in Three Italian Food Chains: A Structural Break Approach AgEcon 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...

Ano: 2009 URL: http://purl.umn.edu/53848 Volatility in Agriculture Commodity Prices in India: Impact and Macroeconomic and Sector-Specific Policy Responses AgEcon 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...

Ano: 2008 URL: http://purl.umn.edu/61234 Grid Pricing: An Empirical Investigation of Market Signal Clarity AgEcon 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.

Ano: 2010 URL: http://purl.umn.edu/93253 Movement Restrictions, Agricultural Trade and Price Transmission between Israel and the West Bank AgEcon 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...

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...

Ano: 2009 URL: http://purl.umn.edu/57344 Specifics in the chosen production chain? AgEcon Pankova, Ludmila. It is possible to consider the production chain as a highly complicated system, within the framework of which different links and mutual relations function. Therefore it is necessary to analyze the complexity of the production chain functioning for the purpose of enhanced knowledge on the existence and the regularities functioning among different production elements. The contribution deals with an analysis of the price transmission in the production chain of cereals, within which only certain partial parts have been earmarked. Cointegration analysis, VECM and impulse-response analysis have been used for the price transmission analysis.

Ano: 2010 URL: http://purl.umn.edu/99069 Price transmission on the Hungarian milk market AgEcon 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...

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....

Ano: 2010 URL: http://purl.umn.edu/91830 Global Market Shocks and Poverty in Vietnam: The Case of Rice AgEcon 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...

Ano: 2011 URL: http://purl.umn.edu/116706 Marketing and pricing dynamics in the presence of structural breaks - the Hungarian pork market AgEcon 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...

Ano: 2006 URL: http://purl.umn.edu/10031 CAP REFORM, WHEAT PRICE INSTABILITY AND PRODUCER WELFARE AgEcon 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.

Ano: 2000 URL: http://purl.umn.edu/21780 Using the Logistic Functional Form for Modelling International Price Transmission in Net Trade Simulation Models AgEcon 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...

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...

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...
