This paper examines the prices for communications equipment, an important component of information technology. Unlike prices for computers which officially fall sharply every year, the official prices for communications equipment have barely budged over the past decade. This paper combines...

New Keynesian macroeconomic models have generally emphasized that expectations of future output are a key factor in determining current output. The theoretical motivation for such forward-looking behavior relies on a straightforward generalization of the well-known Euler equation for...

Empirical estimates of monetary policy rules suggest that the behavior of U.S. monetary policymakers changed during the past few decades. However, at the same time, statistical analyses of lagged representations of the economy, such as VARs, often have not rejected the null of structural...

We seek to analyze the extent and sources of network externalities for the automated clearinghouse (ACH) electronic payments system using a quarterly panel data set on individual bank adoption and usage of ACH. We provide three methods to identify network externalities using this panel data. The...

We began by asking whether the decline in employment among those with disabilities was broad-based or narrowly focused, explained by population shifts or changes in behavior and/or opportunities among those with disabilities, or simply reflective of exogenous deteriorations in health, relatively...

This paper generalizes the Nelson-Phelps catch-up model of technology diffusion. We allow for the possibility that the pattern of technology diffusion can be exponential, which would predict that nations would exhibit positive catch-up with the leader nation, or logistic, in which a country with...

This paper develops new econometric methods to infer hospital quality in a model with discrete dependent variables and non-random selection. Mortality rates in patient discharge records are widely used to infer hospital quality. However, hospital admission is not random and some hospitals may...

Data constraints make the long-term monitoring of the working-age population with disabilities a difficult task. Indeed, the Current Population Survey (CPS) is the only national data source that offers detailed work and income questions and consistently asked measures of disability over a...

The evidence of the last 20 years of recurring output busts and rapid reversals of the current account in emerging markets indicates that domestic agents may not be able to borrow in international capital markets to fully insure themselves against internal and external shocks. This paper models...

In general, our examination suggests that in the absence of a universal guaranteed income program for all Americans, the operational flexibility of the categorical eligibility criteria for SSI has made the program sensitive to both downturns in the business cycle and to increases in the pool of...
