How best to assess trade and industrial policy in developing countries is a controversial question that unlocks a host of modelling complexities. Large computable general-equilibrium (CGE) models dominate many economic policy debates, but recent developments in the field have demonstrated that it is by no means clear that they give reliable results to questions of how trade reforms affect the p...

This paper compares the theoretical and functional specification of production in partial equilibrium (PE) and computable general equilibrium (CGE) models of the global agricultural and food system included in the AgMIP model comparison study. The two model families differ in their scope—partial versus economywide—and in how they represent technology and the behavior of supply and demand in mar...

In this paper we developed and tested an integrated methodology for assessing direct and indirect economic impacts of flooding. The methodology combines a spatial analysis of damage to physical stocks with a general economic equilibrium approach using a regionally-calibrated (to Italy) version of a Computable General Equilibrium (CGE) global model. We applied the model to the 2000 Po river floo...

The traditional cost-benefit analysis (CBA) for transport appraisal has two key weaknesses. Firstly, by assuming static prices in markets external to transport, externalities cannot be considered other than in an ad-hoc, case-by-case manner. This approach is only valid under restrictive assumptions regarding perfect competition and the reflection of marginal costs in prices, which may not be ap...

The global spread of COVID-19 has complicated the international equilibrium grain production and trade. China now faces external shocks in market deep-seated problems associated with structure domestic supply. We used a dynamic, computable general (CGE) model to analyse effects on China’s food security macroeconomics under scenario four technological progress paths agricultural sector. showed t...

The selection of appropriate parameters for computable general equilibrium (CGE) models critically affects the results of applied economic modeling exercises. Valid and reliable parameter selection models are needed, and typically comprise direct estimation, expert opinion, or copycatting of results from seminal studies. The purpose of this study is to use meta-analysis to summarize and more ac...

Computable General Equilibrium (CGE) models have been widely used for quantitative analysis of global economic issues. However, CGE models are frequently criticized for resting on weak empirical foundations. This paper builds on recent work in macro-econometric estimation, developing an approach to parameter estimation for a widely employed global CGE model, the Global Trade Analysis Project (G...

in this paper for calculating policy analysis matrix parameters, with regard to real or shadow prices, we pay attention to variation of endogenous variables, using results of cge  model. the results of the study indicated that,in output market, because of government policies, there are implicit tax on products of iran;s auto industry. but inputs of auto industry, benefits from government subsid...

Energy technologies and innovation are considered to play a crucial role in climate change mitigation. Yet, the representation of technologies in energy-economy models, which are used extensively to analyze the economic, energy and environmental impacts of alternative energy and climate policies, is rather limited. This dissertation presents advanced techniques of including technological innova...
