This paper addresses the case of complementary services with vertical relations. Using the example of airport handling activities, we develop a model to investigate the effects on welfare and competitiveness of four different handling market situations. We find out that the usual Cournot result...

This paper assesses the forecast performance of a set of VAR models under a growing number of restrictions. With a maximum forecast horizon of 12 years, we show that the farther the horizon is, the more structured and restricted VAR models have to be to produce accurate forecasts. Indeed,...

This paper analyses optimal discretionary non-coordinated monetary and fiscal stabilization policies in a micro-founded New-Keynesian model of a two-country monetary union with country-size asymmetry, under two policy scenarios. A balanced-budget policy scenario and a policy scenario where the...

This work concerns the problem of rank estimation in semidefinite matrices, having either indefinite or semidefinite matrix estimator satisfying a typical asymptotic normality condition. Several rank tests are examined, based on either available rank tests or basic new results. A number of...

This study investigates wage determination at the firm level using a longitudinal panel of large firms in Portugal. The results revealed that insider forces such as revenue per employee and market share have a significant impact on wage determination. The results also showed that...

This paper investigates the reasons why firms use fixed-term contracts.Two distinctive features of these contracts - reduced firing costs and the prohibition of contract rollover - are highlighted. Firms' decision related to temporary contracts - the choice of the contract on offer and contract...

This paper is motivated by the recent financial crisis and addresses whether a “too low for too long” interest rate policy may generate a boom-bust cycle. We suggest a model in which a microfounded shadow banking sector is included in an otherwise state-of-the-art DSGE model. When faced with...

Using a longitudinal matched employer-employee data set for Portugal over the 1986-2005 period, this study analyzes the heterogeneity in wages responses to aggregate labor market conditions for newly hired workers and existing workers. Accounting for both worker and firm heterogeneity, the data...

The Portuguese banking sector has been recently subjected to important structural changes. The diversification of the supply of financial services, the specialization phenomena and the growing importance of new technologies are changing the sector dramatically. A profit perspective is used to...

This paper analyses some particular characteristics of merger and acquisition (M&A) transactions in an emerging market (Portugal) using a sample of 52 M&A targets between 1989 and 2001. Our evidence shows that the run-up effect in the Portuguese market is of a significantly larger magnitude (as...
