Public-private partnerships (PPPs) are spreading all over theworld. It may be quite plausible that they were initially startedmainly as an attempt to evade expenditure controls and hidepublic budget deficits. But if they are properly designed andtransparently reported, PPPs can play a useful role in enhancingthe efficiency of the provision of services that were suppliedbefore solely by the public sector. This article provides apublic economics perspective on PPPs. (JEL codes: H54, L33) 相似文献

This paper demonstrates that liquidity risk as measured by the covariation of fund returns with unexpected changes in aggregate liquidity is an important determinant in the cross-section of hedge-fund returns. The results show that funds that significantly load on liquidity risk subsequently outperform low-loading funds by about 6% annually, on average, over the period 1994–2008, while negative performance is observed during liquidity crises. The returns are independent of the liquidity a fund provides to its investors as measured by lockup and redemption notice periods, and they are also robust to commonly used hedge-fund factors, none of which carries a significant premium during the sample period. These findings highlight the importance of understanding systematic liquidity variations in the evaluation of hedge-fund performance. 相似文献

An old person typically has a mixed attitude toward the welfare-state benefits, when they are financed by capital taxes, because
her income derives mostly from capital. We develop a majority-voting model which focuses on the effect of aging on this dilemma.
Surprisingly, the theory predicts that tax rates on capital income could actually rise as the population ages, even though
older individuals would be expected to own more capital than the young and thus vote against higher taxes. We then confront
the key prediction of the model with panel data for ten European Union countries, over the period 1970–1996. We investigate
the asymmetric effect of aging on the taxation of capital and labor. The implications of the model are shown to be consistent
with panel data. JEL no. H0, H5, P1 相似文献

In this paper, we discuss a novel aspect of affirmative action policy. We examine its redistributive role, asking whether in an egalitarian society, supplementing the tax-transfer system with an affirmative action policy would enhance social welfare. We demonstrate that affirmative action could be a desirable policy tool even if racial discrimination does not exist in the labor market. 相似文献

This paper studies the relation between aggregate stock returns and contemporaneous and future cross-sectional earnings dispersion. We hypothesize that increases in expected earnings dispersion signal increases in uncertainty and increases in unemployment, thereby causing expected returns to rise, which in turn causes prices to decline. We find a positive relation between aggregate stock returns and contemporaneous earnings dispersion because higher earnings dispersion is associated with higher expected returns. Consequently, we also find a negative relation between aggregate stock returns and future (one-year ahead) earnings dispersion, as investors anticipate higher future earnings dispersion and higher expected returns. 相似文献

In this paper we demonstrate that in addition to its acknowledged screening role, workfare—namely, introducing work (or training) requirements for welfare eligibility in means-tested programs—also serves to mitigate income misreporting by welfare claimants. It achieves this goal by effectively increasing the marginal cost of earning extra income in the shadow economy for claimants who satisfy the work requirement. We show that when misreporting is sufficiently prevalent, supplementing a means-tested transfer system with work requirements is socially desirable. 相似文献

Foreign direct investment (FDI) is observed to be a predominant form of capital flows to emerging economies, especially when they are liquidity-constrained internationally during a global financial crisis. The financial aspects of FDI are the focus of this paper. We analyze the problem of channelling domestic savings into productive investment in the presence of asymmetric information between the managing owners of firms and other portfolio stakeholders. We explore the role played by FDI in reviving equity-financed capital investment for economies plagued by such information problems. In the presence of information asymmetry, the paper identifies, however, how FDI gives rise to foreign overinvestment as well as domestic undersaving. The gains from trade argument (applied to intertemporal trade) is re-examined in this case of informational-asymmetry-driven FDI. We show that the gains could be sizable when the domestic credit market is either under-developed or failing as a result of a financial crisis. But with a well-functioning domestic credit market, the gains turn into losses. Surprisingly, capital may flow into the country even when the autarkic marginal productivity of capital in the domestic economy falls short of the world rate of interest. In such a situation, capital should have efficiently flown out rather than in, and FDI is a social loss-generating phenomenon. 相似文献

The implications for progression of the benefit approach to the theory of taxation are studied in this paper. It is concluded that the case for progression rests on the degree of substitutability between public and private goods. 相似文献
