关于我国《证券法》修改的若干思考

存在风险条件下的资本市场投资预期收益模型研究

风险是指预期收益的不确定性,是指在将来一段时间内遭受损失的可能性.进行资本市场投资,必然存在风险.资本市场投资风险就是投资预期结果(预期收益损失)的不确定性,有投资风险,就会有投资者对其进行的预期.本文建立了存在风险条件下的资本市场投资预期收益模型,并由此得出了不同投资者的预期收益--风险偏好的不同投资选择.

The Capital Tax and Welfare Effects from Asymmetric Information on Equity Markets

This paper explores the implications of informational asymmetries between domestic and foreign investors for optimal capital tax rates and welfare. It adopts a model in which asymmetric information implies a home bias in equity. The paper finds that asymmetric information may raise capital tax rates by reducing the marginal cost of taxation. Furthermore, it shows that investors may gain from informational asymmetries. Although asymmetric information increases the uncertainty as perceived by investors, it may also increase tax rates and allow for a higher consumption of public goods. This reflects that asymmetric information may reduce the distortionary effects of competition among governments.     

The Role of Omitted Variables in Identifying a Long-run Equilibrium Relationship for the Italian Government Growth

We discuss the role of omitted variables in the long run empirical modeling of the Italian government growth based on a Wagner's Law framework. We identify a non-spurious long-run relationship between general government expenditure and domestic product only when our Wagner's Law model is enhanced by a measure of bureaucratic power, as a supply-side variable, and by the ratio of local to state expenditure, as an institutional factor that captures the division of competencies between local and central government in allocating public expenditure. This result is independent from the Wagner's Law specification chosen. The persistence profile analysis shows a slow adjustment to equilibrium for the estimated government growth relationship following system-wide shocks, pointing to rigidities and complex functioning of the public sector.     

Aging and Retirement: Evidence Across Countries

How do demographic factors influence retirement? Using a large cross-country data set, I show that in countries with a larger share of elderly in their population the length of retirement is longer. This result holds true if I control for wealth effects, and when the effective labor force participation rate of the elderly is used instead of the official retirement age. Retirement policies and the social security size are strictly related: a new variable, representing the aggregate relevance of retirement policies, turns out to be significant in explaining the size of social security. Finally, the total amount of social security transfers is positively related with the increase of the elderly population, while in per capita terms this relation is not significant.
