This article takes the set of Portuguese markets and computes a new competition measure suggested by Boone (2008), which draws on the concept of profit elasticity to marginal costs in a given market. The article concludes that the majority of markets presented a reduction in competition in the...

This article offers an extensive overview of competition indicators in the Portuguese economy in the period 2000-2009. The article covers qualitative competition indicators as well as classicalprofitability and concentration measures, focusing on the differences between tradable and non-tradable...

This paper analyzes the behavior of firms with defaulted credits in terms of recovery or extinction. By defining classes for the severity of default, survival models for the multiple transitions from each class are estimated. The models are used to simulate the evolution of a firm’s credit...

This paper estimates a structural model of the employment decision of the firm. Our establishment level data displays an extreme degree of rigidity in that employment levels are largely constant throughout our sample. This can be due to the fact that establishments face large shocks but also...

Understanding why some firms default, while others do not, is an important issue for the assessment of financial stability. In this domain, it may be interesting to understand if credit risk is driven mostly by idiosyncratic firm characteristics or by systematic factors, which simultaneously...

Quantile regression constitutes a natural and flexible framework for the analysis of duration data in general and unemployment duration in particular. Comparison of the quantile regressions for lower and upper tails of the duration distribution shed important insights on the different...

In this paper we analyse the ability of time and state dependent price setting rules to explain durations of price spells or the probability of changing prices.Our results suggest that simple time dependent models cannot be seen as providing a reasonable approximation to the data and that state...

The U.S. labor market has been experiencing unprecedented high average unemployment duration. The shift in the unemployment duration distribution can be traced back to the early nineties. In this study, censored quantile regression methods are employed to analyze the changes in the US...

Infrequent price changes at the firm level are now well documented in the literature. However, a number of issues remain partly unaddressed. This paper contributes to the literature on price stickiness by investigating the lags of price adjustments to different types of shocks. We find that...
