A simple dynamic IS-LM model with "balanced budget" and money financing deficit can show, in the presence of realistic tax collection lags, regular and chaotic cycles depending on the "mix" of fiscal policies. We argue that also rigid and transparent expenditure limits which an increasing number...

Unemployment and population ageing are probably two of the most important concerns in developed countries. Since reforming labour markets is high on the political agenda, a theoretical knowledge of the possible long-run interaction between unemployment and the childcare system may be highly...

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:...

In this paper we develop a simple model of the labour market in the neoclassical framework dating back to Friedman (1968) and Phelps (1968), among others. According to the existing literature wage expectations should be formed in a different way by firms and individuals in order temporary...

this paper we show that, when elastic labor supply is considered via Cobb Douglas preferences, dynamic inefficiency of OLG economies, while being still a necessary condition, is no longer sufficient for an internal public debt increase to generate a Pareto improvement. This is due to the fact...

The models of technology diffusion originally proposed by Metcalfe (1981), Batten (1987) and Amable (1992) are modified so as to allows for price expectations of adopters and suppliers of an innovation. We show many interesting and somewhat unexpected results, which were not noticed in the...

In the present work we show that, when one allows for endogenous fertility in Diamonds (1965) OLG model, public debt plays still a clear-cut role on dynamic inefficiency (DI): for correcting DI, national debt must be increased. DI is more likely to occur when the economy capital income share and...

In this paper we show that, when endogenous fertility is considered via Cobb-Douglas preferences, public debt plays a clear-cut role on dynamic inefficiency (DI) of an OLG economy: in fact, for correcting the DI problem, debt must be increased (decreased) when the economy is overaccumulating...

In this paper we have developed a "minimalist" Keynesian model (simplified version of Tobin's model, 1975) aiming at demonstrating the existence of endogenous cycles. We have shown that the Tobin's interpretation of the forces governing the stability can be misleading, in that 1) the speculative...

The relationship between wage inflation and unemployment has been extensively investigated since the early work of Phillips (1958) and Lipsey (1960), and is still a matter of debate. In this paper we study the dynamics of a standard neoclassical labour market under Walrasian adjustment rules. We...
