The paper takes up Basesian inference in linear models with disturbances from a non-central Student-t distribution.

This paper constructs a general quilibrium trade model of a small open economy producing an exported good, an imported good and a non-traded good by using two or more factors of production, one of which, namely capital, is imperfectly internationally mobile.

The paper considers Caratheodory's Theorem on the properties of the Inverse of the Bordered Hessian of an Optimization Problem. After a new proof of the complete theorem, using matrix theory methods, the paper considers the sensitivity of the optimal solution in parameters appearing either in...

The Envelope Theorem is showm to involve comparisons between the performance of the optimal policy and that of alternative policies, which satisfy the constraints of the problem and may also have other features. The theorem is activated whenever parameter values are such that the extreme value...

The answer to this question is "yes". We examine noncooperative and cooperative equilibria under perfect capital mobility. To this end, we develop a two-country optimal growth model with endogenous national fiscal policies. The channel for interdependence is distortionary income taxes.

This paper describes various characteristics of illegal migrants in Greece, i.e. country of original marital status, age, sex, education and occupation, as they are reported in their application forms for residence and work permit. It also examines the factors that may affect the migrants choice...

A model of optimal car replacement is developed and used to examine the impact of alternative policy measures on the optimal car replacement time and on total emissions of pollutants, when environment policy takes the form of: (i) reduced taxes on purchaso of "clean" cars, (ii) administrative...

Whilst their products are substituable for the consumer, there exist technological asymmetries across the unionized sectors of an economy. There are high-tech as well as low-tech sectors. We show, that, due to those asymmetries in productivity, inter-sectoral minimum wage agreements may...

This paper investigates if, and how, aternative bargaining agentas may sustain (or, emerge) endogenously, under conditions of centralized wage bargaining, in industries with market power. The wage & employment bargains agenta ("Efficient Bargains") is shown to be a strategic device to induce...

This paper tests the so called "intensification hypothesis" for EU agriculture based on a panel data over the period 1961-1994. The empirical results indicate the acceptance of this hypothesis for all countries, except Portugal. Nevertheless, on statistical grounds, the intensification...
