Previous research has suggested that firms in a number of industrieshave considerable market power, in the sense that their prices exceedtheir marginal costs. However, the observed profits of those industriesare not nearly as high as would occur under full exploitation of the marketpower with a...

We analyze the effect of mergers on various aspects of airline performance during the period 1970-84, using a panel data set constructed by Caves et al. Estimates derived from a simple "matched pairs" statistical model indicate that these mergers were associated with reductions in unit cost. The...

Economic studies typically underestimate incremental changes in consumer goods and design innovations that enhance allocative efficiency and structural dynamics. This paper assesses over 12,000 innovations by female patentees and participants in industrial fairs and prize-granting institutions...

In most cities, the taxi industry is highly regulated and utilizes technology developed in the 1940s. Ride sharing services such as Uber and Lyft, which use modern internet-based mobile technology to connect passengers and drivers, have begun to compete with traditional taxis. This paper...

We embed the microeconomic decisions associated with investment under uncertainty, capacity utilization, and machine replacement in a general equilibrium model based on putty-clay technology. In the presence of irreversible factor proportions, a mean-preserving spread in the productivity of...

This paper studies the implications of procyclical capital utilization rates for inference regarding cyclical movements in labor productivity and the degree of returns to scale. We organize our investigation around five questions that we study using a measure of capital services based on...

In this paper we develop measures of economic capacity output and economic capacity utilization for firms producing multiple outputs and having one or .ore quasi-fixed inputs. Although we produce an impossibility theorem showing that based only on the assumption of cost minimization, the concept...

Productivity reflects not only how efficiently inputs are transformed into outputs, but also how well information is brought to bear on resource allocation decisions. This paper examines this empirically by looking at how on-board computer (OBC) adoption has affected capacity utilization in the...

We propose a simple method to help researchers develop quantitative models of economic fluctuations. The method rests on the insight that many models are equivalent to a prototype growth model with time-varying wedges which resemble productivity, labor and investment taxes, and government...

The extant literature linking slack time to innovation focuses on how slack time facilitates creative activities such as ideation, experimentation, and prototype development. We turn attention to how slack time may enable activities that are less creative but still important for innovation,...
