  5. O que mudou com a Directiva 2009/38/CE, relativa aos Conselhos de Empresa Europeus?

    Costa, Hermes Augusto
    O processo de revisão da Directiva 94/45/CE, que tornou possível a constituição de Conselhos de Empresa Europeus ou procedimentos de informação e consulta dos trabalhadores das empresas de dimensão comunitária, encontrava-se previsto, nos termos do artigo 15º daquela lei comunitária, desde 1999, mas apenas foi consumado em 2009. Este texto trata das principais fundamentações associadas ao “discurso reinvindicativo” dos defensores do processo de revisão da Directiva e das principais mudanças resultantes da nova Directiva em vigor: a Directiva 2009/38/CE, de 6.05.2009.

  7. Business Demography Dynamics in Portugal: A Semi-Parametric Survival Analysis

    Nunes, Alcina; Sarmento, Elsa
    We address the post-entry performance of new Portuguese firms by investigating the structural characteristics of the hazard and survival functions, using semi-parametric survival analysis for the total economy and its broad sectors. In order to approach the prevalence of some stylized facts and determinants of new firm survival, a new entrepreneurship database was produced, using the administrative data of Quadros de Pessoal, following the Eurostat/OECD´s internationally comparable business demography methodology. In line with the literature, we find that firms that start small and experience faster post-entry growth, face a higher probability of survival. Firm’s current size dimension matters particularly for...

  8. Business Demography Dynamics in Portugal: A Non-Parametric Survival Analysis

    Nunes, Alcina; Sarmento, Elsa
    We address the post-entry performance of new Portuguese firms by investigating the structural characteristics of the hazard and survival functions, using non-parametric survival analysis. In order to approach prevalence of some stylized facts and determinants of new firm survival, we produced a new entrepreneurship database, using the administrative data of Quadros de Pessoal, following the Eurostat/OECD´s internationally comparable business demography methodology. This allowed the computation of a comprehensive array of entrepreneurship indicators on employer enterprise and survival dynamics in Portugal, over a period of 18 years, disaggregated in dimensions such as sectors, regions and size classes.

  9. The impact of EU integration on the Portuguese distribution of employees’ earnings

    Andrade, João A. S.; Duarte, Adelaide P. S.; Simões, Marta C. N.
    The accession of Portugal to the EU resulted in several important and different shocks to the Portuguese economy, imposing among others a real positive and lasting effect on employees’ earnings. This paper analyses the impact of Portugal’s accession to the EU in terms of employees’ earnings inequality using data for the years 1985 and 1991 at the Concelhos level from the Quadros de Pessoal database. The two earnings distributions are compared using cardinal measures of inequality and the Lorenz stochastic dominance approach (Araar Abelkrim and Jean-Ives Duclos). The Relative Distribution approach (Mark S. Handcock and Martina Morris) is applied in...

  10. Fiscal sustainability and the accuracy of macroeconomic forecasts: do supranational forecasts rather than government forecasts make a difference?

    Marinheiro, Carlos Fonseca
    Credible fiscal plans that aim at restoring fiscal sustainability will be essential to counter the present increase in debt levels all across Europe. The macroeconomic scenario of such plans will be crucial. This paper assesses whether there is any advantage in delegating (part of) such power to supra-national forecasts. The evidence on the relative performance of the European Commission’s (EC) growth forecast is rather mixed, with considerable variation at the country level. Some national government forecasts (France, Italy, and Portugal) perform worse in terms of descriptive statistics than the EC forecast for all forecast horizons. For the year ahead the...

  11. Estimation of Risk-Neutral Density Surfaces

    Monteiro, A. M.; Tütüncü, R. H.; Vicente, L. N.
    Option price data is often used to infer risk-neutral densities for future prices of an underlying asset. Given the prices of a set of options on the same underlying asset with different strikes and maturities, we propose a nonparametric approach for estimating risk-neutral densities associated with several maturities. Our method uses bicubic splines in order to achieve the desired smoothness for the estimation and an optimization model to choose the spline functions that best fit the price data. Semidefinite programming is employed to guarantee the nonnegativity of the densities. We illustrate the process using synthetic option price data generated using...

  12. Productivity, wages, and the returns to firm-provided training: who is grabbing the biggest share?

    Lopes, Ana Sofia; Teixeira, Paulino
    In spite of the importance of workplace training in human capital accumulation, relatively little is known on its returns for workers and firms. Our investigation tries to fill this gap by developing an alternative modelling that examines the determinants of firm productivity and wages, on the one hand, and the internal rate of return to firm training investments, on the other. Our estimates, obtained using a firm-level dataset in which we have detailed information on firm-provided training, indicate that an additional hour of training per worker implies some 0.1 percent increase in productivity. We also found that 2/3 of the...

  13. Health Status Determinants in the OECD Countries. A Panel Data Approach with Endogenous Regressors

    Poças, Ana; Soukiazis, Elias
    The purpose of this study is to analyse the determinants of life expectancy as proxy for health status of the OECD countries‘ population. A production function of health is used to explain life expectancy at birth for total and ageing population and according to gender. Socio-economic factors, health resources and lifestyles are defined as the main determinants of heath status. The estimation approach assumes that income and education are endogenous and a panel data approach is used to control for this problem. Our evidence shows that income, education and health resources (through consultations) are important factors affecting positively life expectancy...

  14. Employment, exchange rates and labour market rigidity

    Alexandre, Fernando; Bação, Pedro; Cerejeira, João; Portela, Miguel
    There is increasing evidence that the interaction between shocks and labour market institutions is crucial to understanding the dynamics of employment. In this paper, we show that the inclusion of labour adjustment costs in a trade model affects the impact of exchange rate movements on employment. We also explore how labour market rigidities interact with the degree of exposure to international competition and with the technology level. Our model-based predictions are consistent with estimates obtained using panel data for 23 OECD countries. Namely, our estimates suggest that employment in low-technology sectors that have a very high degree of openness to...

  15. Slip Sliding Away: Further Union Decline in Germany and Britain

    Addison, John T.; Bryson, Alex; Teixeira, Paulino; Pahnke, André
    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 in the private sector in Germany and Britain over the period 1998-2004. In both countries within-effects dominate compositional changes as the source of the recent decline in unionism. Overall, the decline in collective bargaining is more pronounced in Britain than in Germany, thus continuing a trend apparent since the 1980s. Although workplace characteristics differ markedly across the two...

  16. The Demand for Excess Reserves in the Euro Area and the Impact of the Current Credit Crisis

    Murta, Fátima Teresa Sol; Garcia, Ana Margarida
    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, since the change in the framework of the single monetary policy in March 2004. Our main conclusions are that there is a positive relationship between the demand for reserves and its financing cost and also that the environment of uncertainty present in the credit crisis is not significant in the demand for...

  17. The performance of the European Stock Markets: a time-varying Sharpe ratio approach

    Fonseca, José A. Soares da
    This article studies the performance of the national stock markets of sixteen European countries (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Holland, Ireland, Italy, Norway, Portugal, Spain, Sweden Switzerland and United Kingdom), using daily data covering the period between 2nd January 2001 and 30th May 2009. Daily expected returns, and the conditional volatility of each index, were calculated using a model combining the market model and an implicit long-term relation between the index prices. Finally, time-varying (conditional) Sharpe ratios were calculated for each index. These were used as the basis for a statistical comparison of the performance of the stock...

  18. Exchange Rate Mean Reversion within a Target Zone: Evidence from a Country on the Periphery of the ERM

    Duarte, António Portugal; Andrade, João Sousa; Duarte, Adelaide
    The aim of this study is to assess to what extent the Portuguese participation in the European Monetary System (EMS) has been characterized by mean reverting behaviour, as predicted by the exchange rate target zone model developed by Krugman (1991). For this purpose, a new class of mean reversion tests is introduced. The empirical analysis of mean reversion in the Portuguese exchange rate shows that most of the traditional unit root and stationarity tests point to the nonstationarity of the exchange rate within the band. However, using a set of variance-ratio tests, it was possible to detect the presence of...

  19. The Extent of Collective Bargaining and Workplace Representation: Transitions between States and their Determinants. A Comparative Analysis of Germany and Great Britain

    Addison, John T.; Bryson, Alex; Teixeira, Paulino; Pahnke, André; Bellmanns, Lutz
    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 firm transitions between these institutions over time. The present paper maps changes in the importance of the key institutions, 1998-2004, and explores the correlates of two-way transitions, using successive waves of the German IAB Establishment Panel and both cross-sectional and panel components of the British Workplace Employment Relations Survey. We identify the workplace correlates...

  20. How well the balance-of-payments constraint approach explains the Portuguese growth performance. Empirical evidence for the 1965-2008 period

    Antunes, Micaela; Soukiazis, Elias
    The present study aims to verify whether the balance-of-payments constrained growth approach is suitable for explaining the Portuguese growth performance during the last decades. For that, we adopt “Thirlwall’s Law” that predicts actual growth by the ratio of the exports growth relative to the income-elasticity of the demand for imports. The income-elasticity of imports, essential for the entire analysis, is obtained from the estimation of the imports function by 2SLS, assuming that domestic growth is endogenous. To smooth cyclical variations, 15-year overlapping periods are considered in the computation of “Thirlwall’s Law”, assuming that income-elasticity with respect to imports is either constant...
