This paper explores the issues arising when the reduced form cointegrating vectors are obtained from an incomplete VAR with omitted endogenous variables. Reconsidering some Wickens' (1996) results, we show that the specification of an incomplete VAR model, based on variables of the reduced form...

This paper offers a critical discussion of the concept of labour market rigidity relevant to explaining unemployment. Starting from Keynes’s own view, we discuss how the concept of labour market flexibility has changed over time, involving nominal or real wage flexibility, contract flexibility...

We analyse the effects of the introduction of a unionised labour market in a simple Diamond's OLG framework. Interesting findings, so far escaped closer scrutiny, emerge. Under some particular conditions about the key parameters of the model, the unionised-wage economy may perform better than...

This paper formally explores the joint roles played, on the one side, by the regulation of wages and, on the other side, by the existence of a “backyard” (or home) technology exploited by the unemployed people, in a standard neoclassical OLG growth model. The main findings are the following:...

Since little attention has been paid to the effects of the regulation of wages on individuals' fertility choice, this paper investigates such effects within a standard OLG model of neoclassical growth. Some new results, so far escaped closer scrutiny by the increasing literature investigating...

Since little attention, despite a long lasting debate, has been paid to the effects of minimum wages on economic growth and welfare, this paper investigates such effects within a textbook OLG framework with an unemployment insurance scheme financed at balanced budget by the government with a...

The paper compares different strands of New Keynesian Economics with respect to Keynes's original work on wages, describing which are the most relevant differences and analogies. In particular, two issues are analysed in detail. First, the explanations provided by Keynes and New Keynesians of...
