Resumo: The literature has typically assumed that the effect of overeducation on wages is constant over the conditional wage distribution. In this paper, we use quantile regression and data from 12 European countries to show that the overeducation wage effect may differ largely across segments of the distribution. By differentiating between quantiles, we discriminate between groups of workers with different (unobservable) skills. We find that the detrimental effects of overeducation among the high-skilled are indeed higher than among the lowskilled. This finding lends support to the view that overeducation is an event that reduces the worker’s potential productivity, regardless of his skills.

In this paper, we measure the impact of the application of IFRS to financial information of Portuguese public companies belonging to the Eurolist by Euronext Lisbon. The results show that the Balance Sheet and Income Statement structures of the firms studied suffered relevant accounting conversions in the process of compliance. Nevertheless, we did not find a clear pattern for the accounting variations. IFRS implementation conditioned the measure made to the performance and the financial position of the business companies in Portugal.

It reports data on the Portuguese distributions of income, labor earnings, and capital income, and on related features of inequality, such as age, employment status, educational attainment, marital status and economic mobility. It also documents changes in inequality from 1994 to 2001, a period of economic expansion in Portugal. The statistical significance of the observed changes is assessed using non-parametric tests based on bootstrap techniques. The paper shows that income, earnings, and, very especially, capital income are very unequally distributed in Portugal. It also shows that over the sample years income and earnings inequality decreased, whilst capital income inequality tended to increase.

In particular, we derive results concerning the expected optimal timing for relocation, the corresponding volatility and the value of the firm under the optimal relocation policy. Impacts on the final results driven by the characteristics of the firm´s original location site, the market environment and the way in which risk is modeled, are studied numerically. The overall results are in line with economic intuition. Thu, 01 Mar 2007 00:00:00 GMT http://hdl.handle.net/10400.3/4761 2007-03-01T00:00:00Z
