We study the welfare effect of tax-optimizing portfolio decisions in a life cycle model with unspanned labor income and realization-based capital gain taxation. For realistic parameterizations of our model, certainty equivalent welfare gains from fully tax-optimized portfolio decisions are less than 2% of present financial wealth and lifetime income compared to a heuristic portfolio policy ignoring the taxation of profits (capital gains, interest and dividend payments). Compared to a heuristic portfolio policy that only ignores the realization-based feature of capital gain taxation and instead assumes mark-to-market taxation, these gains are less than 0.5%. That is, our work provides a justification for ignoring taxes in life cycle portfolio choice problems – a wide-spread assumption in that literature. However, if capital gains are forgiven at death (as in the U.S.), investors with strong bequest motives face substantial welfare costs when not tax-optimizing their portfolio decisions towards the end of the life cycle. 相似文献

We present new tests for the form of the volatility function which are based on stochastic processes of the integrated volatility. We prove weak convergence of these processes to centered processes whose conditional distributions are Gaussian. In the case of testing for a constant volatility the limiting process are standard Brownian bridges. As a consequence an asymptotic distribution free test and bootstrap tests (for testing of a general parametric form) can easily be implemented. It is demonstrated that the new tests are more than the currently available procedures. The new approach is also demonstrated by means of a simulation study. 相似文献

Harsh Evaluations of Entrepreneurs Who Fail: The Role of Sexual Orientation,Use of Environmentally Friendly Technologies,and Observers' Perspective Taking 下载免费PDF全文
Although there is a pervasive anti‐failure bias in society, we investigate why some entrepreneurs who fail are evaluated more harshly than others. Building on attribution theory and the literatures on prejudice, pro‐social intentions, and perspective taking, we offer an evaluation model of entrepreneurial failure and test this model on 6,784 assessments made by 212 observers. We find that variance in the harshness of failure evaluations depends on both the attributes of the entrepreneur and the attributes of the observer, and the interaction between the two. Specifically, entrepreneurs who are homosexual are evaluated more harshly by some observers and entrepreneurs who use environmentally friendly technology are evaluated less harshly. Moreover, observers high in perspective taking are more ‘lenient’ in their failure evaluations of those who use environmentally friendly technology than those low in perspective taking. 相似文献

Abstract. In this paper we analyse productivity spillovers from foreign direct investment using firm-level panel data for U.K. manufacturing industries from 1992 to 1999. We investigate spillovers through horizontal, backward, and forward linkages; distinguish spillovers from export-oriented vs domestic-market-oriented FDI; and allow for differing effects, depending on domestic firms' export activities. The results suggest that the mechanisms through which spillovers affect domestic firms are very complex and that there are substantial differences in spillover benefits for domestic exporters and non-exporters, and from different types of inward investment. 相似文献

This paper analyzes gender differences in the disposition effect in an experiment based on Weber and Camerer (1998). The results emphasize that female investors realize less capital losses, have significantly higher disposition effects and are more loss averse than men. 相似文献

This paper investigates two sourcing strategies of firms, outsourcing and importing, and links these to innovation activities. The authors examine this empirically using firm‐level data for 28 emerging market economies and find robust evidence that outsourcing increases the likelihood to spend on R&D and via this channel raises innovation output, whereas importing increases innovation output, but not R&D. The results hold when implementing an instrumental variables approach. It is found that results crucially depend on the institutional environment in the economy, e.g. property rights and intellectual property rights protection. The results suggest that better institutions magnify the gains from importing, but not from outsourcing. EU countries also reap additional positive innovation effects from importing compared with non‐EU countries. 相似文献

Stock externalities and ecological interaction have similar equilibrium effects. The influence on the dynamics of an ecosystem, however, is quite different. The different effects are laid out theoretically in the context of a forest-air model. We compare a centralized, welfare-maximizing policy and decentralized policies. Finally, we numerically simulate the dynamic differences between stock externalities and ecological interaction. 相似文献

This study investigates the interaction of the use of modern contraceptives, fertility, education, and long‐run growth. It develops an economic model that takes into account that sexual intercourse is utility enhancing and that birth control by modern contraceptives is more efficient but more costly than traditional methods. The study shows how a traditional economy, in which modern contraceptives are not used, gradually converges toward a high growth regime, in which modern contraceptives are used. Lower prices or higher efficacy of contraceptives are conducive to an earlier onset of the fertility transition and a quicker takeoff to modern growth. 相似文献

This paper investigates to what extent individuals' risk preferences are correlated with the cross-sectional earnings risk of their occupation. We exploit data from the German Socio-Economic Panel, which contains a direct survey question about willingness to take risks that has been shown to be a behaviorally valid measure of risk aversion. As a measure of earnings risk, we use the cross-sectional variation in earnings that is left unexplained by human capital variables in Mincerian wage regressions. Our evidence shows that individuals with low willingness to take risks are more likely to work in occupations with low earnings risk. This pattern is found regardless of the level of occupation categories, region, gender and labor market experience. 相似文献
