John Commons' influence in American labor economics was eclipsed after World War II by a resurgent neoclassical labor economics that gradually relegated Commons' institutional orientation to the periphery of economic discourse. A common opinion is that the work of institutional economists in the...

In the context of testing for a unit root in a univariate time series, the convention is to ignore information in related time series. This paper shows that this convention is quite costly, as large power gains can be achieved by including correlated stationary covariates in the regression...

This article reviews David Hendry's Econometrics: Alchemy or Science?

Although theologians and economists communicate their ideas to different professional audiences in different ways, we agree on many basic points. We agree, for instance, that all too often, a large gap appears between "what is" and "what should be." We agree, more specifically, that unregulated...

The macroeconomic evidence on the short-term impact of exchange rates on exports and prices is notoriously weak. In this paper I examine the micro-foundations of this disconnect by looking at firms' export and price setting decisions in response to fluctuations in exchange rates and credit...

Can increased uncertainty about the future cause a contraction in output and its components? This paper examines the role of uncertainty shocks in a one-sector, representative-agent dynamic stochastic general-equilibrium model. When prices are flexible, uncertainty shocks are not capable of...

We study Ramsey-optimal fiscal policy in an economy in which product varieties are the result of forward-looking investment decisions by firms. There are two main results. First, depending on the particular form of variety aggregation in preferences, firms' dividend payments may be either...

I characterize cyclical fluctuations in the cross-sectional dispersion of firm-level productivity in the U.S. manufacturing sector. Using the estimated dispersion, or "risk," stochastic process as an input to a baseline DSGE financial accelerator model, I assess how well the model reproduces...

In this paper we hypothesize that greater macroeconomic uncertainty would cause firms to increasingly turn to their suppliers as a source of finance, making greater use of trade credit. We test this hypothesis using a panel of non-financial firms drawn from the annual COMPUSTAT database and show...
