Some empirical extrapolations are performed which indicate that if the process of disaggregation were to be carried sufficiently far (to approximately the 17th to 23rd SITC level), virtually all intra-industry trade could be expected to disappear from international trade statistics. It is also...

An n-commodity, n-factor, K-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 large-scale econometric models is to replace the ``true model'' by an aggregative one in which the variables are grouped and replaced by sums or weighted averages of the variables in each group. The modes of aggregation of the independent and dependent...

This paper estimates trade-demand functions for Germany from monthly data covering the period 1959-1988. It is assumed that these trade-demand functions have the form of the Linear Expenditure System, generated by a shifted Cobb-Douglas trade-utility function in which the shift parameter is...

This paper considers explicit representations for very general (discrete and continuous-time) intertemporal consumption-maximization models which allow the instantaneous preferences of the consumer and the time-preference factors to vary over time and for the non-existence of utility functions,...
