We investigate if the long-run underperformance in the year after the issue of a sample of Spanish SEO firms is related to behavioural biases that lead investors to slowly adjust their pre-issue overoptimism. We also examine the existence of arbitrage costs that preclude mispricing from being corrected rapidly by sophisticated investors who act as arbitrageurs. Our findings support the contention that small SEO firms are overpriced at the time of the issue and suggest that their post-underperformance is related to arbitrage costs, where transaction costs play an important role although holding costs do not. 相似文献

The role of credentials in the Canadian labour market 总被引:3,自引:1,他引:2
We study the role of credentials or 'sheepskin effects' in the Canadian labour market. Sheepskin effects refer to increases in wages associated with the receipt of a degree after controlling for educational inputs such as years of schooling. We find strong evidence of sheepskin effects associated with graduation from high school, community college or trade school, and university. The importance of credentials increases with educational attainment, accounting for 30 per cent of the return to 16 years of schooling but more than half of returns above 16 years. Our evidence indicates that both years of schooling and degree completion influence earnings. JEL Classification: I2, J3
Le rôle des certificats dans le marché du travail au Canada. Les auteurs étudient le rôle des certificats ou des «effets de parchemin>> dans le marché du travail au Canada. Les effets de parchemin font référence aux augmentations de salaires associées à l'obtention d'un diplôme ou d'un grade après avoir pris en compte l'expérience éducationnelle comme les années d'éducation. On découvre des résultats probants pour ce qui est des effets de parchemin associés à l'obtention d'un diplôme d'école secondaire, de collège communautaire, d'école technique, et d'université. L'importance de la certification augmente avec le niveau d'instruction : elle compte pour 30 pourcent du rendement pour 16 années de scolarité mais pour plus de la moitié des rendements pour la scolarité au delà de ces premiers 16 ans. Les résultats indiquent que tant les années de scolarité que la certification comme telle ont un impact sur les gains. 相似文献

Correct estimation of the Outstanding Claims Reserve, an item that includes Incurred But Not Reported Claims (IBNR) as well as Incurred But Not Enough Reserved Claims (IBNER), is one of the most important issues currently facing actuarial science, due to its effect on the technical and financial stability of insurance companies. The purpose of this paper is to calculate the reserve in a decision-making environment, so that estimates can be made according to accurately defined and previously established rational criteria. Specifically, the estimating process enables a company’s particular situation to be taken into account, by incorporating its approach to the consequences arising from estimation errors into the model. The proposed calculation method gives rise to optimum link ratio estimators that can also be interpreted from a Bayesian perspective, with the advantages associated to such methodology. 相似文献

Structural Breaks and the Relationship between Barley and Wheat Futures Prices on the London International Financial Futures Exchange 总被引:1,自引:0,他引:1
Co-movement between futures prices can arise when commodities are substitutes. Counterintuitively, Dawson and White fail to find a significant long-run link between feed barley and wheat prices on the London International Financial Futures Exchange. This relationship is re-examined using Johansen, Mosconi, and Nielsen's co-integration procedure that permits structural breaks. Results show evidence of co-integration and hence price discovery. There is a significant break in October 2000 following Common Agricultural Policy intervention price reductions, the barley–wheat futures market is perfectly integrated, and the barley price Granger-causes the wheat price. Modeling structural breaks in price relationships appears important. 相似文献

Patent Licensing Under Strategic Delegation 总被引:2,自引:0,他引:2
Ana I. Saracho 《Journal of Economics & Management Strategy》2002,11(2):225-251
The modern corporation is characterized both by a separation of ownership from management and by managerial incentives that often include strategic elements in addition to the standard incentive elements. Despite the importance of these two features in the agency and corporate-governance literatures, they are absent in the treatment of the firm in the patent-licensing literature. The analysis in this paper shows how, by simply taking into account these two features of the modern corporation, it is possible to offer a new explanation for the use of royalties in licensing agreements. 相似文献

We introduce a negative effect of technological development on human capital accumulation in a growth model with endogenous innovation and accumulation of human capital. This implies a negative externality of R&D in human capital accumulation. Some calibration exercises suggest that this distortion may be sufficiently strong not only to offset the usual effects of spillovers and of returns to specialization but also to induce overinvestment in R&D. 相似文献

This article examines optimal nonlinear taxes with worker mobility. We devise a model in which two qualitatively different types of workers choose to live in either of two jurisdictions. Residence decisions and labor–leisure choices are influenced by the tax schedules operating in the two regions. Within worker category, individuals may differ in attachment to one or the other of the regions. We show how worker mobility affects the optimal tax schedule, and address the spatial distribution of the population under optimal taxation. We examine a special case in which it is possible to make statements about the second-best distribution of population. 相似文献

This paper proposes a model to predict recessions that accounts for non‐linearity and a structural break when the spread between long‐ and short‐term interest rates is the leading indicator. Estimation and model selection procedures allow us to estimate and identify time‐varying non‐linearity in a VAR. The structural break threshold VAR (SBTVAR) predicts better the timing of recessions than models with constant threshold or with only a break. Using real‐time data, the SBTVAR with spread as leading indicator is able to anticipate correctly the timing of the 2001 recession. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

中国开放型经济发展绩效评估研究 总被引:2,自引:0,他引:2
在对开放型经济内涵界定基础上,构建了中国开放型经济绩效评估综合指标体系并对1985~2012年中国开放型经济发展绩效进行了实证评估,评估结果表明:中国开放型经济发展绩效已形成了显著的倒U型曲线趋势特征,自2007年后呈现持续下降态势。进而文章从外部因素和内部因素两方面对近年来中国开放型经济发展绩效下降的主要原因进行了剖析并提出了相应对策与建议。 相似文献
