Última Increased Cocoa Bean Exports under Trade Liberalization: A Gravity Model Approach AgEcon Yeboah, Osei-Agyeman; Shaik, Saleem; Wozniak, Shawn J.; Allen, Albert J.. Gravity models were developed to estimate the potential bilateral exports of cocoa under trade liberalization by the sixteen major cocoa producing countries to the US using panel data from 1989 to 2003. The results indicate that differences between resource endowment, relative size of economies, and the sum of bilateral GDP of U.S. and exporting countries are the major determinants. Thus, as trade is liberalized, farmers share of the world price of cocoa increases and this raises exports.

Ano: 2008 URL: http://purl.umn.edu/6819 Market Reforms, Spatial Price Dynamics, and China's Rice Market Integration: A Causal Analysis with Directed Acyclic Graphs AgEcon Awokuse, Titus O.. Previous studies on post-reform market performance of Chinese grain markets have produced mixed results. This paper employs province-level price data to determine if China's food market liberalization policies in the 1990s resulted in interregional rice market integration. Furthermore, this study extends the literature on spatial market integration by augmenting multivariate cointegration modeling techniques with directed acyclic models (DAGs), a recently developed statistical method for analyzing contemporaneous causal relationships. While the empirical results confirm the existence of strong market linkages subsequent to the reforms of the early 19902, the linkages became less as the Chinese government reversed several reform policies in the mid-1990s....

This study examines the effect of European intervention politics in the European butter market in the context of market liberalization using the example of Germany. A heteroscedastic Tobit model is estimated using German butter market data from 1973-2010. There is evidence that price support has reduced price instability in the butter market. Simulation indicates that enhancing intervention price causes an increase in the expected butter price in the long-run, even though if market price is higher than intervention level. We find changing effects of stockpiling. If difference between market and intervention price is small and stock quantity is high, it significantly contributes to reducing price volatility. On the contrary if price difference is large and...

Ano: 2012 URL: http://purl.umn.edu/122528 An Econometric Analysis of Price Dynamics in the Presence of a Price Floor: The Case of American Cheese AgEcon Chavas, Jean-Paul; Kim, Kwansoo. In this paper, we present an econometric analysis for the effects of a price floor on price dynamics and price volatility. A price floor (implemented as a part of government pricing policy) provides a censoring mechanism for price determination. We specify and estimate a dynamic Tobit model under time-varying volatility. The model is applied to analyze the effects of a price support program on price dynamics and price volatility in the U.S. American cheese market. The econometric analysis provides useful insights on price dynamics in the presence of a government-determined price floor.

Ano: 2005 URL: http://purl.umn.edu/43628 Modeling agricultural production risk and the adaptation to climate change AgEcon Finger, Robert; Schmid, Stephanie. A model that integrates biophysical simulations in an economic model is used to analyze the impact of climate change on crop production. The biophysical model simulates future plant-management-climate relationships and the economic model simulates farmers' adaptation actions to climate change using a nonlinear programming approach. Beyond the development of average yields, special attention is devoted to the impact of climate change on crop yield variability. This study analyzes corn and winter wheat production on the Swiss Plateau with respect to climate change scenarios that cover the period of 2030-2050. In our model, adaptation options such as changes in seeding dates, changes in production intensity and the adoption of irrigation farming are...

Ano: 2007 URL: http://purl.umn.edu/9270 What Does Liberalization without Price Competition Achieve? The Case of Cocoa in Ghana. AgEcon Vigneri, Marcella; Santos, Paulo. The deregulation of Ghana’s domestic cocoa supply chain that took place in the early 1990s was expected to bring competition among different private buyers and to generate a number of production incentives to the farmers. Most notably, it was expected that competition would emerge by means of price bonuses and/or premiums over the guaranteed price. However, this paper finds that price based competition mechanisms did not develop in the resulting domestic cocoa value chain. Rather, the now increasing numbers of Licensed Buying Companies compete for cocoa supplies based on the provision of different services to farmers. The availability of a number of outlets offers farmers the option to choose among those that can provide cash as well as credit. The...
