In this article we deal with the identification problem within the Dynamic Linear Models family and show that using Bayesian estimation procedures we can deal better with these problems in comparison with the traditional Maximum Likelihood estimation approach. Using a Bayesian approach supported...

Parameter uncertainty has been a recurrent subject treated in the financial literature. The normative portfolio selection approach considers two main kinds of decision rules: expected expected utility maximization and mean-variance criterion. Assuming that the mean-variance criterion is a good...

In this paper, we calculate the realized volatility measures using intraday data not equally spaced in time. The aim is to compare these measures with the ones from the stochastic volatility model. With this model, the data used are obtained in equal time intervals. Known facts are that the...

This paper presents the first comparative analysis of the decline in collective bargaining in two European countries where that decline has been most pronounced. Using workplace-level data and a common model, we present decompositions of changes in collective bargaining and worker representation...

Nesta comunicação procurei mostrar a originalidade da política monetária do Banco Central Europeu (BCE), a dificuldade de uma avaliação conclusiva da sua acção e o contexto teórico da sua intervenção. Também foi feita uma avaliação da sua capacidade de resposta à actual crise,...

In this study, we develop an alternative modelling that examines a) the determinants of firm productivity and wages and b) the internal rate of return (IRR) to firm training for both firms and workers. Using a six-year linked employer-employee dataset, our estimates indicate that an additional...

One of the risks that banks need to manage, in their financial intermediation activities, is liquidity risk. Thus, banks hold reserves for precautionary reasons, in order to keep enough cash to meet their obligations. In this work, we analyze the demand for excess reserves by Euro Area banks,...

Industrial relations are in flux in many nations, perhaps most notably in Germany and Britain. That said, comparatively little is known in any detail of the changing pattern of the institutions of collective bargaining and worker representation in Germany and still less in both countries about...

Atypical work arrangements have long been criticized as offering more precarious and lower paid work than regular open-ended employment. In an important paper published in this journal, Booth et al. (2002) were among the first to recognize that notwithstanding their potential deficiencies, such...

Will the current crisis accelerate the PIGS collapse? We approach the subject by comparing the responses of the unemployment rate to an output shock on those economies (Portugal, Italy, Greece and Spain) with those of a benchmark economy – the USA. Our methodological strategy relies on one of...
