An overlapping generations model is set up in this paper to analyze social security policy in a representative democracy with asymmetric information. The model considers not only redistribution between generations but also redistribution within generations according to individual labor incomes....

This paper analyzes intergenerational redistribution in a 2-period overlapping-generations model of a representative democracy. The model incorporates redistribution between generations and redistribution within generations, allowing for heterogeneous labor productivities in the working...

The Ramsey approach to optimal taxation and Ramsey tax rules have amassed substance in economic theory. However, they are often criticized on grounds of practicality, fairness, feasibility and some other aspects of designing actual tax policy. This paper presents a collection of these views; it...

The paper studies the macroeconomic effects of government spending shocks in an economy characterized by positive trend growth. It shows that the lower is the trend growth rate the less inflationary are government spending shocks and vice versa. Moreover, on impact output is higher but exhibits...

In this paper redistribution policy is analyzed in a 2-period overlapping generations model with heterogeneous individuals and asymmetric information between the government and the private sector. Individuals of the same generation differ with respect to their labor productivity. In each period,...

A popular interpretation of the Rational Expectations/Efficient Markets hypothesis states that, if the hypothesis holds, then market valuations must follow a random walk. This postulate has frequently been criticized on the basis of empirical evidence. Yet the assertion itself incurs what we...

Models in which firms use a rule of thumb or partial indexing in price setting are prominent in the recent monetary policy literature. The extent to which these firms adjust their prices to lagged inflation has been taken as fixed. We consider the implications of firms choosing the optimal...

The paper develops a model of firm´s investment under uncertainty with financial market imperfections and analyzes the effects of financial constraints on firm´s investment. Firm´s investment is an increasing function of the firm´s marginal q, however the investment function is characterized...

This paper argues that the production constraints in the basic NAIRU model should be distinguished by type: capital constraints and labour constraints. It notes the failure to incorporate this phenomenon in standard macro models. Using panel data for UK manufacturing over eighty quarters it is...

The economies of Central and Eastern Europe are undergoing a period of rapid structural change. The general pattern confirms to the J-curve anticipated by several observers at the start of transition. This paper conceptualises the J-curve as the result of a combination of two factors. First,...
