In this paper we critically reappraise some measures of the importance of time-dependent price setting rules and propose an alternative way to gauge the significance of this type of price setting behaviour. The merits of the proposed measure are highlighted in an application using micro-data....

This paper analyses the results of a survey conducted by the Banco de Portugal between May and September 2004 on a sample of 1370 Portuguese firms with the main purpose of investigating their price setting behaviour. The evidence points to the presence of a considerable degree of price...

Taking stock of the recent developments in the New Open Macroeconomics literature, we build a two country Dynamic Stochastic General Equilibrium (DSGE) model of the euro area and the US, with nominal rigidities and imperfect exchange rate passthrough. The model is calibrated using parameters...

This paper introduces persistent productivity shocks in a continuous-time mononopolistic competition model of trade with hetererogenous firms similar to Melitz (2003). In our model, the presence of sunk costs and uncertainty have three main consequences: first, firms export decisions become...

We analyze the longevity of foreign entrants explicitly considering two possible ways of exit: firm closure and capital divestiture. We find that entry and post-entry strategies affect the longevity of firms and of foreign equity holdings, but in different manners. While the ownership...

In this paper, we analyze the implications of price setting restrictions for the conduct of cyclical fiscal and monetary policy. We consider an environment with monopolistic competitive firms, a shopping time technology, prices set one period in advance, and government expenditures that must be...

In this paper we study the effects of quality change on the price index for new passenger cars in Portugal for the years 1997-2001. Hedonic regression models are studied, giving particular emphasis to the relation between the form of the price index and the specification of the hedonic equation...
