风险资本规模与最优投资组合   总被引:1,自引:0,他引:1  
对于任何一个风险投资基金来说,都涉及到投资组合规模问题。由于在投资策略中奉行积极干预的策略,风险投资家耗费了大量的精力和时间。因此,风险资本规模的扩大对风险投资家的投资结构可能会产生影响。这就引致出风险投资最优投资组合的问题,并涉及对风险投资收益率的影响。  相似文献

We estimate the impact of taxation on foreign direct investment (FDI) flows, using data on flows between seven countries for 1984 through 1989, and a sophisticated measure of the cost of capital. We find that the choice between domestic investment and total outward FDI is not significantly affected by taxation but that taxation does affect the location of outward FDI. These results are used to examine the impact of tax integration systems. Giving a tax credit to foreign shareholders may induce a large increase in inward FDI from exemption countries but not from partial-credit countries. For the United States, the total effect would be small.  相似文献

This paper contrasts real effective exchange rate (REER) measures based on different deflators (consumer price index, GDP deflator, and unit labor cost) and discusses potential implications for the link—or lack thereof—between the REER and the external balance. We begin by comparing the evolution of different measures of REER to confirm that the choice of deflator plays a significant role in REER movements. A subsequent empirical investigation based on 35 developed and emerging market economies over 1995–2017 yields comprehensive and robust evidence that only the REER deflated by unit labor cost exhibits contemporaneous patterns consistent with the expenditure-switching mechanism. Finally, we show that a standard open-economy model with nominal rigidities and trade in intermediate goods is able to generate these aforementioned patterns.  相似文献

Economic Risk Factors and Commercial Real Estate Returns   总被引:1,自引:1,他引:0  
A great deal of research has focused on the links between stock and bond market returns and macroeconomic events such as fluctuations in interest rates, inflation rates, and industrial production. Although the comovements of real estate and other asset prices suggests that these same systematic risk factors are likely to be priced in real estate markets, no study has formally addressed this issue. This study identifies the growth rate in real per capita consumption, the real T-bill rate, the term structure of interest rates, and unexpected inflation as fundamental drivers or state variables that systematically affect real estate returns. The finding of a consistently significant risk premium on consumption has important ramifications for the vast literature that has examined the (risk-adjusted) performance of real estate, for it suggests that prior findings of significant abnormal returns (either positive or negative) that have ignored consumption are potentially biased by an omitted variables problem. The results also have important implications for dynamic asset allocation strategies that involve the predictability of real estate returns using economic data.  相似文献

This study investigates the potential for farmland to improve mixed-asset portfolio efficiency. Three major conclusions are drawn from the research. First, in a world with certainty, farmland can be shown to statistically improve mixed-asset portfolio efficiency. Second, with the introduction of uncertainty into the portfolio allocation model, investors can justify small or no allocations of farmland in a mixed-asset portfolio, although it appears that even with uncertainty prudent investors should evaluate the asset class. Third, with respect to farmland investment and geographic diversification, the results question the ability of an optimized mean–variance portfolio to provide substantial improvement in comparison to a naïve portfolio. The marginal improvement in portfolio efficiency of an optimized farmland portfolio versus a naïve farmland portfolio is not statistically significant.  相似文献

This study examines investor performance in IPOs using a unique database comprising 85,384 investors and 29 offerings from Finland. The evidence indicates that on average institutional investors do not obtain larger initial returns than retail investors, as the incentive to acquire information is limited by allocation rules which favour small orders. This result is in contrast to findings by Aggarwal et al . (2002), who show that institutional investors perform better in a bookbuilding environment. Within each investor category, however, large orders are associated with the best performance, suggesting that information differences figure more importantly within rather than between categories.  相似文献
