An n-commodity, n-factor, A"-country log-linear model is developed, with identical Cobb-Douglas production coefficients and identical consumer expenditure shares across countries, in which factor endowments are such as to permit positive production of all commodities in all countries, hence...

A widely used method in the analysis of complex econometric models is to replace the "true model" by a highly simplified aggregative one in which the variables are grouped and replaced by sums or weighted averages of the variables in each group. The analysis of the problem of choosing an...

This volume collects three independent contributions which discuss the role of computable general equilibrium (CGE) modelling in both research and teaching. The first paper by John Chipman suggests that statistical methods could be incorporated into CGE analysis. He argues that this would allow...

Aggregation may be harmful but cannot always be avoided in the analysis of complex econometric models. It should be carried out intelligently by choosing ein aggregative model optimally for modes of aggregation speeified in advance, i.e. minimizing the bias introduced by aggregation and...

Do incentives and policy choices of public officials depend on whether they are appointed by an elected body or directly elected by voters? I investigate this question using the example of state grants for highly visible municipal investment projects. To attract these grants, mayors must prepare...

We investigate non-linearities in the stock return - trading volume relationship by using daily data for 16 European countries in an asymmetric vector autoregressive model. In this framework, we test for asymmetries and analyze the dynamic relationship using a simulation based procedure for...

This paper explores the role of public debt and fiscal deficits on factor productivity in an economy with credit market frictions and heterogeneous firms. When credit market conditions are sufficiently weak, low interest rates permit the government to run Ponzi schemes so that permanent primary...

In many groups heterogeneous incentives induce people to make unequal contributions to a common pool. This paper studies whether people consider the random assignment of such unequal incentives as unequal opportunities and demand more egalitarian distributions of the pool. The aggregate...
