Three Essays On Contract Farming In China, Jianhua Zhu Jan 2007

Three Essays On Contract Farming In China, Jianhua Zhu

Retrospective Theses and Dissertations

Contract farming in China has grown rapidly over the past 10 years. The first part of this dissertation examines the evolution of contract farming, and explores the incentives to engage in contract farming, preferred contract provisions, and contract performance from the perspective of both Chinese farmers and contracting firms. Firm and household perceptions of contracting are assessed using data obtained from village and firm level surveys. Farmers identify price stability and market access as the key advantages to contracts, while firms consider improved product quality as the primary incentive to use contracts.;In Part II, the survey data are used ...


Essays On International Trade, Endogenous Quality And Invasive Species Risk , Anh Thuy Tu Jan 2005

Essays On International Trade, Endogenous Quality And Invasive Species Risk , Anh Thuy Tu

Retrospective Theses and Dissertations

This dissertation studies the relation between international trade and two issues that have become the active fields of economic research: the firms' quality decisions and the invasive species risk.;On the quality choice, the dissertation focuses on the impact of Voluntary Import Expansions (VIEs) on firms' quality decisions. I model a vertically differentiated international duopoly, with one firm in each country. A domestic and an exporting firm choose the quality of their goods and then compete in the domestic market. Both quantity and price conjectures are considered. The paper investigates the case where the government of the exporting country imposes ...


Optimal Trade Policy, Time Consistency And Uncertainty In An Oligopsonistic World Market , Jean-Philippe Gervais Jan 1999

Optimal Trade Policy, Time Consistency And Uncertainty In An Oligopsonistic World Market , Jean-Philippe Gervais

Retrospective Theses and Dissertations

This dissertation investigates the strategic behavior between countries that have purchasing power on the world market for a certain good. Tariffs and quotas are not equivalent protection instruments under non-cooperative behavior. Importers would be better off by choosing their policy cooperatively. If production decisions occur before consumption decisions, the ex-ante optimal policy is not time consistent because the ex-post elasticity of the residual foreign export supply is lower than the ex-ante elasticity. However, we show that the importers' inability to commit to their trade instrument may be welfare superior to the precommitment solution;We derive the equilibrium production policies if ...


Generalized Corner Solution Models In Recreation Demand , Daniel James Phaneuf Jan 1997

Generalized Corner Solution Models In Recreation Demand , Daniel James Phaneuf

Retrospective Theses and Dissertations

When examining consumer behavior using household level data, it is typical in many applications to find that consumers consume only a subset of the available goods, setting their demand to zero for the remaining goods. Examples of this include labor supply and food demand, as well as the demand for Leisure Studies; In multiple site recreation demand data sets, one usually observes that individuals visit only a subset of the available recreation sites, yet visit these sites multiple times during a season. Theoretically, these corner solutions are effectively modeled using non-negativity constraints in the utility maximization problem. Empirically estimating such ...


An Agricultural Policy And Trade Model For Morocco , Mohamed Jaouad Jan 1994

An Agricultural Policy And Trade Model For Morocco , Mohamed Jaouad

Retrospective Theses and Dissertations

The properties of duality were exploited in developing an integrated system consistent with endogenous behavior of producers, consumers, and government for Moroccan agriculture. A multi-output, multi-input normalized quadratic profit function was used to derive product supply equations for crops and livestock products and variable input demand equations for fertilizer, grain feed, and other feed products. For domestic demand and import share equations, an AIDS framework was applied to derive demand elasticities. As an alternative to the traditional excess demand approach, and to represent the outcomes of a reformed and open cereal sub-sector in Morocco, the study introduces a module that ...


The Political Economy Of International Agricultural Protection , Virender Gautam Jan 1993

The Political Economy Of International Agricultural Protection , Virender Gautam

Retrospective Theses and Dissertations

The purpose of this study has been to investigate some prominent determinants of agricultural protection across industrialized and developing countries. The hypotheses tested are that consumers' food security concerns and producers' pressure group characteristics play an eminent role in the determination of political market equilibrium in the agricultural sector. The methodology employed provides an integrated development of theoretical and empirical analysis;The comparative static results of the theoretical models are tested using the ordinary least squares, generalized least squares, pooled cross-section time-series, and Probit and Logit estimation techniques. The analysis includes data from 30 industrialized and developing countries for the ...


Demand For Risky Foods And Food Safety , Kung-Cheng Lin Jan 1993

Demand For Risky Foods And Food Safety , Kung-Cheng Lin

Retrospective Theses and Dissertations

A demand for risky food model is constructed to study several aspects of food safety problems. On the basis of this proposed model, results are addressed in the following. First, when the food safety is exogenously fixed, an increase in the safety level of the risky food X[subscript]1 increases the demand for X[subscript]1 if X[subscript]1 is normal. However, when both goods are risky, a rise in the safety level of one good generally has an ambiguous effect on the demands. For the case where the safety level is endogenously chosen, the consumer will in ...
