Empirical studies of the external effects of R&D suggest that both geographic and technological distance attenuate inter-firm spillovers from innovative activity. The results presented here indicate that the tendency for R&D spillovers to localize economic activity is conditional on the...

We consider an environment in which participants make payments over a network and can invest in a technology that reduces the marginal cost of using the network. A network effect results in multiple equilibria; either all agents invest and usage of the network is high or no agents invest and...

This paper examines the extent to which firm-specific levels of auditor-independence are codetermined with alternative inputs to governance production. We identify a number of governance-producing mechanisms that are causally or simultaneously related to auditor independence. These results are...

Models of the monetary transmission mechanism often generate empirically implausible business fluctuations. This paper analyzes the role of on-the-job search in the propagation of monetary shocks in a sticky price model with labor market search frictions. Such frictions induce long-term...

This study examines the problem of forecasting an aggregate of cointegrated disaggregates. It first establishes conditions under which forecasts of an aggregate variable obtained from a disaggregate VECM will be equal to those from an aggregate, univariate time series model, and develops a...

This paper examines the asymptotic and finite-sample properties of tests of equal forecast accuracy applied to direct, multi-step predictions from both non-nested and nested linear regression models. In contrast to earlier work -- including West (1996), Clark and McCracken (2001, 2005),and...

We investigate implications of search and matching frictions in the labor market for in ation targeting interest rate policy in terms of equilibrium stability. When the interest rate is set in response to past or present in ation, determinacy of equilibrium is ensured similarly to comparable...

This paper investigates potential market forces that cause payment card rewards even when providing payment card rewards is not the most efficient. Three factors-oligopolistic merchants, output-maximizing card networks, and the merchant's inability to set different prices across payment...
