This paper proposes a two-equation price-wage model that enables to test whether the inflationary pressure on wage rate is only present when the rate of inflation is greater than some threshold value. Since the likelihood function for this model is very nonstandard, we develop a small-sample...

This article seeks to improve understanding of cross-country patterns of economic growth. It adopts a stochastic production-frontier model that allows for the decomposition of output change into input, efficiency, and technical change. The production frontier is assumed to depend on effective...

We represent random vectors Z that take values in n-{0} as Z=RY, where R is a positive random variable and Y takes values in an (n-1)-dimensional space . By fixing the distribution of either R or Y, while imposing independence between them, different classes of distributions on n can be...
