Specification choice and robustness in CGE trade policy analysis with imperfect competition
نویسنده
چکیده
In order to contribute to a more comprehensive understanding of the robustness of the quantitative results of applied trade policy simulations to variations in the assumptions about firm conduct, this article provides a systematic synopsis of alternative formulations of imperfectly competitive supply behaviour in applied general equilibrium trade models and examines the sensitivity of simulated trade policy effects to the specification choice and calibration strategy within a prototype multi-country model. The analysis suggests in particular, that simulation results are generally far more sensitive to numerical specification choices at the calibration stage, than to the prior choice of firm conduct specification.

Scale Economies and Imperfect Competition in the GTAP Model
The universe of existing CGE models can be divided into 3 broad categories. The first class of models (of which the standard GTAP model is a classic example) emphasizes the static effects of policy related to general equilibrium resource reallocation. The second involves scale economics and imperfect competition and the third involves dynamic accumulation effects. Development of the second clas...

Recent strong growth of China’s exports has elevated the country to a rising global economic power and caused geo-political concern to policy-makers in the country and its trading partners world-wide. What are the determinants of this growth, how has it affected major economies in ASEAN (World Bank, 2009) in particular, and what kind of evidence-based responses are required and appropriate? The...

Trade liberalization is often the core attention of foreign economic strategies in developing countries. Findings in the literature confirm a significant effect of free trade on developing economies through which the economic sectors benefit from technology transfer and spillovers and increasing production capacities and input productivity leading to international competitiveness. On the other...
متن کاملHospital Choice for Cataract Treatments: The Winner Takes Most
Background Transparency in quality of care is an increasingly important issue in healthcare. In many international healthcare systems, transparency in quality is crucial for health insurers when purchasing care on behalf of their consumers, for providers to improve the quality of care (if necessary), and for consumers to choose their provider in case treatment is needed. Conscious consume...
متن کاملInternational Trade and Environmental Policy Under Imperfect Competition
The objective of the present paper is to review the literature on the link between environmental policy and international trade, with a focus on imperfect competition on the world output markets. Special attention will be paid to the literature on oligopoly and strategic government policy and its potential consequences for the ecological dumping debate. We address partial equilibrium as well as...
