Until the outbreak of the recent economic and financial crisis, Spain was leading the ranking of countries with the largest share of temporary employees. During the crisis this share has fallen to its lowest level in decades, but this does not mean that working conditions in Spain have improved. The flow of new temporary contracts is larger than ever before. A particularly striking feature is the steep growth in the volume of fixed-duration contracts lasting less than a week or a month. We document these trends and analyse how this phenomenon has affected the transition from temporary to permanent employment. 相似文献

We employ an innovative methodology suggested by Bernhardt et al. (J. Financ. Econ. 80:657–675, 2006) to examine the herding (or anti-herding) behavior of German analysts regarding earnings forecasts. This methodology avoids
well-known shortcomings often encountered in related studies, such as correlated information signals, unexpected common shocks
to earnings, systematic optimism or pessimism, or forecast target mismeasurement. Our findings suggest that German analysts
anti-herd, that is, they systematically issue earnings forecasts that are further away from the consensus forecast than their
private information indicates. Furthermore, we analyze the association between herding behavior and different characteristics,
including the size of the brokerage, general or firm-specific experience, and the coverage of firms on the Neuer Markt. We mainly confirm findings for the United States, for example, that anti-herding is more severe in cases of higher competition
among analysts. Contrary to anecdotal evidence, we also find anti-herding behavior in earnings forecasts for Neuer Markt firms during the “new economy” bubble.

In this paper, we develop a continuous time factor model of commodity prices that allows for higher-order autoregressive and moving average components. We document the need for these components by analyzing the convenience yield’s time series dynamics. The model we propose is analytically tractable and allows us to derive closed-form pricing formulas for futures and options. Empirically, we estimate a parsimonious version of the general model for the crude oil futures market and demonstrate the model’s superior performance in pricing nearby futures contracts in- and out-of-sample. Most notably, the model substantially improves the pricing of long-horizon contracts with information from the short end of the futures curve. 相似文献

Post Offices Inc. in The Netherlands has developed and implemented a new instruction model for the training of desk employees. The quality of the new instruction model was assessed by means of the evaluation model of Jacobs and Jones for on‐the‐job training. It is concluded that the implementation of the training model has not been completely successful. Critical success factors, such as the performance of the mentors as well as the quality of the self‐study material, have to be improved. Mentors are expected to serve as a behavioural model, to provide feedback, arrange an adequate environment for self‐study, motivate trainees for self‐study and evaluate trainees’ progress on a regular basis. This study shows that mentors must be fully convinced of the benefit of a new instructional model, if not, the implementation will not be successful. Besides, the study shows that the quality of the self‐study material depends very much on the similarity between the knowledge needed in work and the knowledge presented in the self‐study material. 相似文献

Stochastic Generational Accounting Applied to Reforms of Dutch Occupational Pensions 总被引:1,自引:0,他引:1
This paper examines stochastic or ‘value based’ generational accounting as a method to assess the intergenerational redistributive impact of pension reform. The analysis is applied to three policy changes to the regulation of Dutch occupational pensions during the years 2012 and 2013 that mark the transition from defined benefit pensions to ‘defined ambition’ pension schemes. 相似文献

The problems that social and labour market institutions are facing today are often attributed to globalisation and ageing.
This article argues that globalisation merely exposes inherent weaknesses in social institutions while ageing aggravates them,
but that neither of the two phenomena is the fundamental cause of the challenges. Moreover, there is no inherent trade-off
between social and economic policies, but to reconcile the policies comprehensive modernisation is needed. Each country can
face the challenges should they wish to do so and converging to a single social model is neither needed nor wanted. Finally,
European (economic) and national (social) policies become increasingly intertwined and this calls for a new role for Europe.

Abstract On connaît le rôle que joue le théorème de Parseval. dans la théorie des séries de Fourier et, plus généralement, dans celle des développements suivant des fonctions orthogonales. On sait aussi qu'on peut généraliser la notion d'orthogonalité ainsi que le théorème de Parseval de différentes manierès, p. ex. en se servant de l'intégrale de Stieltjes correspondant à, une distribution de masses positives. 相似文献

We develop a standard model to show how transaction costs in international investment affect conventional tests of consumption risk sharing, both in a multilateral and a bilateral setting. We implement the tests in a novel international data set on bilateral holdings of equity, bonds, foreign direct investment (FDI) and bank loans. In our data, high foreign capital holdings are associated with international consumption risk sharing as implied by our theory. This is especially true of investment in equity or bonds, but not of foreign direct investment or bank loans. In our model, the implication is that transaction costs are higher for FDI and international loans. The discrepancy could reflect technological differences, but also the prospect of expropriation, perhaps most stringent for FDI or loans. We argue that expropriation risk is endogenous to both the borrower's institutions and its openness to international markets. The detrimental impact of poor institutions is muted in open economies, where the possibility of subsequent exclusion from world markets deters expropriation of foreign capital. We show the implied effects of institutions prevail in both the cross-section of consumption risk sharing and in observed international investment patterns. 相似文献

This article studies the portfolio problem with realization-based capital gain taxation when limited amounts of losses qualify for tax rebate payments, as is the case under current US tax law. When the tax rate applicable to realized losses exceeds that on realized capital gains, it can be optimal to realize capital gains immediately and pay capital gain taxes to regain the option to use potential future losses against a higher tax rate. This incentive adds an entirely new and as yet unstudied dimension to the portfolio problem. It causes risk averse investors to hold more equity and attain higher welfare levels than is the case when trading under a tax system that seeks to collect the same amount of taxes, but does not allow for tax rebate payments. This is because the benefit to these investors from having their losses subsidized is greater than the suffering from having profits taxed at a higher rate. 相似文献
