Traditional computable general equilibrium (CGE) models based on the Armington assumption fail to capture the extensive margin of trade, and thereby underestimate the trade and welfare effects of trade opening. To address this problem, this paper introduces the Melitz (2003) theoretical framework with firm heterogeneity and fixed exporting costs into a global CGE model. Some illustrative simula...

this paper examines the effects of agricultural land productivity improvement on the economy of iran assuming that the domestic and international trade liberalizations will open up the opportunities to expand market access. a 25-sector computable general equi-librium model was developed to simulate the effects of this policy. the simulation results indicate that enhancing agricultural land prod...

A passenger transport model, Asia-pacific Integrated Model (AIM)/Transport, incorporating travelers’ mode of choice and transport technological details was developed in this study. This AIM/Transport was coupled with the AIM/Computable General Equilibrium (AIM/CGE) to capture interactive mechanisms between the transport sector, energy consumption, greenhouse gas (GHG) emissions, and the macro-e...

Cladophora glomerata extract (CGE) has been shown to exhibit antigastric ulcer, anti-inflammatory, analgesic, hypotensive, and antioxidant activities. The present study investigated antidiabetic and renoprotective effects of CGE in type 2 diabetes mellitus (T2DM) rats. The rats were induced by high-fat diet and streptozotocin and supplemented daily with 1 g/kg BW of CGE for 12 weeks. The renal ...

Despite the implementation of the first phase of fuel subsidy targeting in December 2010, there are still debates over the economic impact of this project in Iran. A CGE model is used to analyze the impact of fuel subsidy targeting in Iran in four different scenarios. The data are used in the framework of SAM for the year 2001. In all scenarios, indirect subsidies are removed completely and rep...

This paper carries out a survey of CGE and Microsimulation models used in the evaluation of issues related directly or indirectly to incomes distribution. Different model structures are discussed which have been employed for country-specific, multi-country and region-specific studies. The paper considers the relevance of a relatively recent approach in modeling_linking CGE frameworks with micro...

This paper describes FiFoSiM, the integrated tax benefit microsimulation and computable general equilibrium (CGE) model of the Center of Public Economics at the University of Cologne. FiFoSiM consists of three main parts. The first part is a static tax benefit microsimulation module. The second part adds a behavioural component to the model: an econometrically estimated labour supply model. The...

Practitioners and academics apply a range of regional economic models for impacts assessment. These models extend from a simple economic base through to input-output and econometric models and computable general equilibrium models. All such models have strengths and weaknesses. Dimensions of which impact assessment models are often compared include level of industry detail, data availability, a...
