We discuss how to avoid aggregation bias in large-scale global Computable General Equilibrium (CGE) models by reducing the need of pre-model aggregation, based on the combination of algorithmic improvements and a filtering approach which removes small transactions. Using large-scale sensitivity analysis, we show the impact of pre-aggregation and filtering on model size, model solution time and ...

This paper uses a multi-period economic-environmental CGE modelling framework to analyse the impacts of natural population change and the relaxation of migration constraints in a labour-constrained economy. Population and environmental concerns are core elements of sustainable economic development policy in the target economy of Jersey. Specifically, CGE model simulations are used to track the ...

Special events are typically regarded as major generators of economic activity and jobs. Despite its continued use in event assessment, Input-Output (I-O) analysis has been rejected in other areas of economic impact evaluation in favor of more rigorous evaluation techniques that recognize resource constraints in the economy and interindustry effects of demand shocks. This article discusses trad...

GABAergic interneurons critically regulate cortical computation through exquisite spatiotemporal control over excitatory networks. Precision of this inhibitory control requires a remarkable diversity within interneuron populations that is largely specified during embryogenesis. Although interneurons expressing the neuronal isoform of nitric oxide synthase (nNOS) constitute the largest hippocamp...

The consensus in the literature investigating the causes of increased wage inequality in developed nations since 1980 is that skill-biased technical change is responsible for the widening of the wage distribution. A shortcoming in this literature is that technical change is commonly determined residually; that is, those changes in relative wages unexplained by other factors are attributed to ch...

This paper proposes a procedure to incorporate the conjectural variation approach in Computable General Equilibrium (CGE) analysis such that the strategic interaction among rival firms in international markets can be modelled. It shows how to calibrate the conjectured reactions of rival domestic and foreign firms. It also shows that the approach suggested by Harrison, Rutherford and Tarr (hence...

We study the problem of measuring the uncertainty of computable general equilibrium (CGE) (or RBC)-type model simulations associated with parameter uncertainty. We describe two approaches for building conŽ dence sets on model endogenous variables. The Ž rst uses a standard Wald-type statistic. The second approach assumes that a conŽ dence set (sampling or Baycsian) is available for the free par...

The abundant natural resources can bring either positive or negative impact to the country’s economy depending on the macroeconomic policies. Mongolia has massive mineral resource dominated by coal, copper, and gold. The Government of Mongolia has started to implement a number of infrastructure projects to decrease the mining project’s cost burden caused from the country’s weak infrastructure. ...

Alternative approaches to modelling distributional and welfare effects of changes in policy and the economic environment in developing and transition countries are surveyed. Microsimulations range from pure accounting approaches to models with behavioural equations based on econometric estimates and various dynamic models. Microsimulation accounting models are key to analysing the impact effect...
