Mark-up cyclical behaviour is relevant in determining the size of government spending multiplier on output. While theoretical literature priviliged the counteryclical hypothesis, empirical evidence is far from being conclusive. Based on seminal Rotemberg and Saloner (1986) contribution, we build...

We characterize the equilibrium in a homogeneous good Cournot duopoly in which firms have the choice to react to a cost-push shock by paying a lump-sum adjustment cost in order to offset the initial rise in marginal cost. Our results show that the size of the shock and the size of the adjustment...

We revisit the two-stage duopoly game with strategic delegation and asymmetric technologies of Sen and Stamatopoulos (2015). We show that their conclusions are misled by the restrictive assumption that the extent of delegation to managers is restricted to a binary set. Allowing for a continuous...

We revisit the discussion about the relationship between price's cyclical features, implicit collusion and the demand level in an oligopoly supergame where a positive shock may hit demand and disrupt collusion. The novel feature of our model consists in characterising the post-shock...

In this paper we set up a NK-DSGE model in which the consumer derives utility from a consumption basket made of public and private consumption, there is monopolistic competiton in the intermediate good sector, Calvo-Yun price setting, endogenous labour supply and Taylor rule for monetary policy....

This paper develops a three periods OLG growth model where agents accumulate human capital in the first period (benefiting from grandfathers savings, public expenditure in education, and human capital level of their parents), work and save in the second period (earning a salary proportional to...

Using the simple arithmetic of government budget constraint, we perform an analysis on the Italian case, investigating the consequences on the main public finance aggregates of the adoption of a fiscal policy rule responding to past real debt/GDP ratio. Such a rule, firmly grounded in the...

The objective of this paper is to investigate the optimality of EMU fiscal rules from a welfare perspective. We compute welfare-maximizing feedback coefficients for monetary and fiscal rules in a NK-DSGE with a high number of nominal and real distortions, calibrated on the Euro-area data. The...

Average hourly productivity has often been used to draw conclusions on long run per capita GDP growth, based on the assumption of full utilization of labour resources. In this paper, we argue that a failure to recognize the potentially significant wedges among the two variables – even in the...

This paper presents a New Economic Geography model with distortionary taxation and endogenized trade costs. Tax revenues finance a public good, infrastructure. We show that the introduction of costly public investment in infrastructure increases agglomerative tendencies. With respect to the...
