Flexible Life Annuities

Annuity contracts typically deliver a stream of income at a predetermined level in order to insure against the risk of longevity. This paper explores whether flexible annuities, which give subscribers the possibility to choose between different levels of annuity, are welfare enhancing. In the case where agents gradually discover their actual probability of survival, a predetermined and "one-size-fits-all" annuity plan is optimal. If an expenditure risk is added along with the longevity risk, a flexible annuity plan is better even though the consumption path cannot be isolated from uninsured expenses anymore.     

GENDER INEQUALITY IN EDUCATION IN CHINA: A META‐REGRESSION ANALYSIS

Although there is evidence that there was gender inequality in China's education system in the 1980s, the literature in China has mixed evidence on improvements in gender inequality in educational attainment over the past three decades. Some suggest gender inequality is still severe; others report progress. We seek to understand the progress China has made (if any) in reducing gender inequality in education since the 1980s. To meet this goal, we use a meta‐analysis approach which provides a new quantitative review of a relatively large volume of empirical literature on gender educational differentials. This article analyzes differences across both time and space, and also across different grade levels and ethnicities. Our results indicate that gender inequality in educational attainment still exists, but it has been narrowing over time. Moreover, it varies by area (rural versus urban) and grade level. There is nearly no significant gender inequality in the case of girls in urban areas or in the case of the 9 years of compulsory education (primary school and junior high school). Girls, however, still face inequality in rural areas (although inequality is falling over time) and when they reach high school or beyond. (JEL I24)     

Optimal Redistributive Taxation in a Search Equilibrium Model

This paper characterizes optimal non-linear income taxation in an economy with a continuum of unobservable productivity levels and endogenous involuntary unemployment due to frictions in the labour markets. Redistributive taxation distorts labour demand and wages. Compared to their efficient values, gross wages, unemployment, and participation are lower. Average tax rates are increasing. Marginal tax rates are positive, even at the top. Finally, numerical simulations suggest that redistribution is much more important in our setting than in a comparable Mirrlees-type setting.     

Multiple Equilibria in Markets with Screening

This paper adds endogenous screening to Broecker (1990) and shows the possibility of multiple screening equilibria. A high intensity of screening by a bank decreases average quality of firms applying to other banks, which in turn have further incentives to screen. The link between the degree of concentration of the banking industry and the extension of credit is also discussed.
