Subprime mortgage design

This paper offers evidence on the design of subprime mortgages as bridge-financing products. We show that the viability of subprime mortgages was uniquely predicated on the appreciation of house prices over short horizons. High rates of early prepayments on subprime mortgages suggest the use of prepayments as an exit option. This paper argues that high early defaults on post-2004 originations can be explained when one considers high early prepayment rates for pre-2004 originations.     

Aggregate Investment Externalities and Macroprudential Regulation

Evidence suggests that banks tend to lend a lot during booms and very little during recessions. We propose a simple explanation for this phenomenon. We show that instead of dampening productivity shocks, the banking sector tends to exacerbate them, leading to excessive fluctuations of bank credit, output, and asset prices. Our explanation relies on three ingredients that are characteristic of modern banks’ activities: moral hazard, high exposure to aggregate shocks, and the ease with which capital can be reallocated to its most productive use. At the competitive equilibrium, banks offer privately optimal contracts to their investors, but these contracts are not socially optimal: banks reallocate capital excessively upon aggregate shocks. This is because banks do not internalize the impact of their decisions on asset prices. We examine the efficacy of possible policy responses to these properties of credit markets, and derive a rationale for macroprudential regulation in the spirit of a Net Stable Funding Ratio.

论小康生活实现的特点与走向

我国小康生活的实现具有速度快、指标全面、覆盖率高和实现内容现代化等优势特点，同时也存在着城乡差别、地区差别、各地区城镇差别和各地区农村差别的非均衡性特点，因此，应根据我国小康生活实现的这一特点，继续完成部分地区由温饱向小康的过渡、鼓励部分地区由小康向富裕过渡进而全面建设优质小康生活，为本世纪中叶实现富裕生活水平而奠定基础。     

Equilibrium theory with asymmetric information and with infinitely many commodities

The traditional deterministic general equilibrium theory with infinitely many commodities cannot cover economies with private information constraints on the consumption sets. We bring the level of asymmetric information equilibrium theory at par with that of the deterministic one. In particular, we establish results on equilibrium existence for exchange economies with asymmetric (differential) information and with an infinite dimensional commodity space. Our new equilibrium existence theorems include, as a special case, classical results, e.g. Bewley [Existence of equilibria in economies with infinitely many commodities, J. Econ. Theory 4 (1972) 514-540] or Mas-Colell [The price equilibrium existence problem in topological vector lattices, Econometrica 54 (1986) 1039-1053].     

Unemployment insurance with hidden savings

This paper studies the design of unemployment insurance when neither the searching effort nor the savings of an unemployed agent can be monitored. If the principal could monitor the savings, the optimal policy would leave the agent savings-constrained. With a constant absolute risk-aversion (CARA) utility function, we obtain a closed form solution of the optimal contract. Under the optimal contract, the agent is neither saving nor borrowing constrained. Counter-intuitively, his consumption declines faster than implied by Hopenhayn and Nicolini (1997) [1]. The efficient allocation can be implemented by an increasing benefit during unemployment and a constant tax during employment.
