This paper presents a model in which some goods trade in "customer markets." In these markets, advertising plays a critical role in facilitating long-lived relationships. We estimate both policy and non-policy parameters of the model (which includes New-Keynesian frictions) on U.S. data,...

This paper evaluates the effects of fiscal policy on investment using a panel of OECD countries. In particular, we investigate how different types of fiscal policy affect profits and , as a result, investment. We find a sizable negative effect of public spending -- and in particular of its...

The paper examines the evolution of consumption patterns in Organization for Economic Co-operation and Development (OECD) countries from 1985 to 1999. Estimation of demand function parameters uncovered consistent evidence that differences in consumption patterns have recently diminished between...

The fact that raising taxes can increase taxed labor supply through income effects is frequently used to justify greater public good provision than indicated by traditional, compensated analyses. We develop a model including multiple public goods and taxes and derive consistent measures of the...

We discuss instrumental variables (IV) estimation in the broader context of the generalized method of moments (GMM), and describe an extended IV estimation routine that provides GMM estimates as well as additional diagnostic tests. Stand-alone test procedures for heteroskedasticity,...

This paper presents a model in which "instrument uncertainty"-that is, an uncertain mapping from monetary policy to macroeconomic outcomes-may mitigate the inflationary bias problem that arises when efficient monetary policy rules are time- inconsistent. If the relation between monetary policy...

A number of previous studies have questioned the dominant role of Germany within the EMS. These conclusions are often based on empirical findings that interest rates of member countries of the EMS are not affected by German interest rates, even in the long run. In this study we establish...

This paper studies two roles that long-term nominal interest rates can play in the conduct of monetary policy in a New Keynesian model. The first allows long-term rates to enter the reaction function of the monetary authority. The second considers the possibility of using long-term rates as...

Let y be a vector endogenous variables and let w be a vector of covariates, parameters and errors or unobservables that together are assumed to determine y. A structural model y=H(y,w) is complete and coherent if it has a well defined reduced form, meaning that for any value of w there exists a...

In this paper we re-examine commercial banks' lending behavior taking into account changes in the stance of monetary policy in conjunction with changes in financial sector uncertainty. Using a very large data set covering all banks in the US between 1986-2000, we show that financial uncertainty...
