In a continuous time life cycle model of consumption with uncertain lifetime and no ''pure time preference", we use a non-parametric specification of rank dependent utility theory to characterize the preferences of the agents. From normative point of view, the paper discusses the implication of...

A well-known common agreement in decision theory is that only exponential decision makers are time consistent i.e. with the mere passage of time, future choices must not contradict the initial choice. Building on this result, a large range of works has studied time inconsistency as a direct...

Over the past two decades, the Maghreb Countries have initiated a liberalization process characterized by increasing trade flows and they have strengthened economic and financial linkages between their economies. In this paper, we demonstrate how co-movements of outputs would respond to this...

Firms devote significant resources to maintain and repair thei existing capital. Within a real business cycle model featuring arguably small aggregate increasing returns, this paper assesses the stabilizing effects of fiscal policies with a maintenance expenditure allowance. In this setup, firms...

We study the implications of constant money growth rules on the stability properties of the equilibrium, in economies where the agents are subject to a partial cash-in-advance constraint applying simultaneously to consumption and investment purchases. By reference to similar models in which the...

We incorporate imperfectly insured unemployment in the finance constrained economy proposed by Woodford (1986), by introducing unions and unemployment benefits financed by labor taxation. We show that this simple extension of the Woodford model changes drastically its stability conditions and...

We provide a business cycle model in which endogenous markup fluctuations are the main driving force. These fluctuations occur due to some form of 'animal spirits', impelling firms in their entry-exit decisions within each sector. By contrast to existing models of the business cycle emphasizing...

This paper questions the impact of trade integration on business cycle sychronization in the EMU by distinguishing increase of existing trade flows (the intensive margin) and creation of new trade flows (the extensive margin). Using a DSGE model, we find that synchronization is weakened when new...

Economies with oligopolistic markets are prone to inefficient sunspot fluctuations triggered by autonomous changes in firms equilibrium conjectures. We show that a well designed taxation-subsidization scheme can eliminate these fluctuations by coordinating firms in each sector on a single...

Standard stochastic growth models provide theoretical restrictions on output decomposition which can be used to investigate whether productivity shocks played a major role in observed business cycles. Applying these restrictions to US data leads to the following findings: i) Business cycles...
