This paper estimates the extent to which market power is a source of production misallocation. Productive inefficiency occurs through more production being allocated to higher cost units of production, and less production to lower-cost production units, conditional on a fixed aggregate quantity....

Production functions are a central component in a variety of economic analyses. However, these production functions often first need to be estimated using data on individual production units. There is reason to believe that, more than any other input in the production process, there are severe...

We separately observe variable input expenditure and expenditure on fixed inputs in novel firm-level data covering the Belgian manufacturing sector over the last decades. This permits a deeper investigation of two potential drivers of the globally observed widening gap between firms' revenue and...

We propose a general equilibrium model with oligopolistic output markets where two channels can cause a change in market power: (i) technology, via changes to productivity shocks and the cost of entry, (ii) market structure, via changes to the number of potential competitors. First, we...

To answer the question whether managers are paid for market power, we propose a theory of executive compensation in an economy where firms have market power, and the market for man- agers is competitive. We identify two distinct channels that contribute to manager pay in the model: market power...

To date, little is known about the evolution of market power for the economies around the world. We extract data from the financial statements of over 70,000 firms in 134 countries, and we analyze and document the evolution of markups over the last four decades. We show that the average global...
