This paper explores how different margins of market share are related to markups. Using merged microdata on producers and consumers, we document that a firm's market share is mainly related to its number of customers, while its price-cost markup is associated only with its average sales per...

I show that buyer power of firms could either increase or decrease their technology adoption, depending on the direction of technical change and on which input markets are imperfectly competitive. I examine this relationship empirically in a setting that features both concentrated labor markets...

Job differentiation gives employers market power, allowing them to pay workers less than their marginal productivity. We estimate a differentiated jobs model using application data from Careerbuilder.com. We find direct evidence of substantial job differentiation. Without the use of instruments...

This paper rehabilitates the old wage price spiral. It shows that, after an increase in aggregate demand, the process of adjustment of nominal prices and nominal wages results from attempts by workers to maintain or increase their real wage and by firms to maintain or increase their markups of...

The rise in the share of labor costs invalue added in many industrial countries during the 1970s and early 1980s has led many observers to conclude that real wages are now too high and a source of "classical" unemployment. These conclusions are not necessarily valid. The increase in the labor...

The purpose of this paper is to compare the behavior of an economy subject to labor contracts with an economy where the labor market clears in an auction manner. Such a comparison is intended to reveal the information content of real wages in a flexible economy. The analysis reveals two distinct...

This paper examines the desirability of wage indexation in an open economy subject to economic disturbances which change the terms of trade and raise the prices of imported goods. Two indexation rules are considered, the traditional form of indexation to the consumer price index and indexation...

The persistence of inflation during periods of high unemployment poses the central problem for macroeconomic policy in coming years. The extent of success in reducing both inflation and unemployment will depend strongly on the short-run responsiveness of wage inflation to unemployment and excess...

We document that variations in government purchases generate a rise in consumption, the real and the product wage, and a fall in the markup. This evidence is robust across alternative empirical methodologies used to identify innovations in government spending (structural VAR vs. narrative...

This paper presents a model in which firms recruit both unemployed and employed workers by posting vacancies. Firms act monopsonistically and set wages to retain their existing workers as well as to attract new ones. The model differs from Burdett and Mortensen (1998) in that its assumptions...
