This paper exposits and relates two distinct approaches to bounding the average treatment effect. One approach, based on instrumental variables, is due to Manski (1990, 1994), who derives tight bounds on the average treatment effect under a mean independence form of the instrumental variables...

This lecture outlines an asymmetric information theory of financial instability which describes the fundamental forces which harm both the financial sector and economic activity. This asymmetric information framework is then used to demonstrate that although international capital movements and...

This paper estimates a dynamic model of schooling attainment to investigate the sources of discrepancy by race and ethnicity in college attendance. When the returns to college education rose, college enrollment of whites responded much more quickly than that of minorities. Parental income is a...

This paper examines the international experiences with four basic types of monetary policy regimes: 1) exchange-rate targeting, 2) monetary targeting, 3) inflation targeting, and 4) monetary policy with an implicit but not an explicit nominal anchor. The basic theme that emerges from this...

This paper attempts to provide a perspective on the causes of inflation by exploring why sustained inflations occur and the role of monetary policy in the inflation process. The conclusion reached in this paper is that in the last ten years there has been a convergence of views in the economics...

Several recent studies find that ex ante real returns for short-term U.S. Treasury securities are negatively correlated both with inflation and with nominal interest rates. This paper examines whether these findings extend to the short-term holding return on publicly and privately issued...

This paper surveys new methods for estimatifg labor supply functions. A unified framework of analysis is presented. All recent models of labor supply are special cases of a general index function model developed for the analysis o dummy endogenous variables

This paper presents new econometric methods for the empirical analysis of individual labor market histories. The techniques developed here extend previous work on continuous time models in four ways: (1) A structural economic interpretation of these models is presented. (2) Time varying...

A heated debate has arisen over what Modigliani has dubbed the Macro Rational Expections (MRE) hypothesis. This hypothesis embodies two component hypotheses: 1) rational expectations and 2) short-run neutrality -- i.e., that anticipated changes in aggregate demand will have already been taken...
