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 study determined the effect of temperature on the gonotrophic cycle of Culiseta melanura and developed a thermal heat summation model to calculate its duration under field conditions. A colony of Cs. melanura was used from New Jersey (F13-F17 generation) and the length of the gonotrophic cycle was observed at 2, 10, 16, 22, 28, 32 and 34 degrees C. None of the mosquitos survived at 2 degre...

In this paper, I analyze a dynamic model of a firm’s joint decisions to export and innovate, allowing both decisions to affect the firm’s production in accordance with selfselection and learning-by-exporting theories of firm-level export and production dynamics. I calibrate the model using Chilean manufacturing plant data from 2005 to 2007 and find that self-selection and learning-by-exporting ...

We develop a model to analyze the implications of "ring costs on incentives for R&D and international specialization. The key idea is that countries with a rigid labor market will tend to produce relatively secure goods, at a late stage of their product life cycle. Consequently, their researchers tend to specialize in &secondary innovation' which improves existing products, rather than &primary...

Two hundred and five Escherichia coli strains isolated from calves with diarrhea from mid-western Brazil were screened for the presence of virulence factors associated with bovine colibacillosis. One hundred and two (49.8%) of the E. coli strains produced toxins: Shiga toxins 1 (9.7%) and 2 (6.3%), α-hemolysin (9.7%), enterohemolysin (6.8%), Cytotoxic Necrotizing Factors type 1 (0.5%), and type...

This paper advocates computable general equilibrium (CGE) models as an analytical framework that is suitable for assessing the impacts of policy interference on the three dimensions of Sustainable Development, i.e. environmental quality, economic performance and equity. Methodological extensions of standard CGE models are illustrated that may strengthen the role of CGE models in measuring polic...
