Working Paper
Relative price dispersion: evidence and theory
REVISED: 8/1/18: We use a large data set on retail pricing to document that a sizable portion of the cross-sectional variation in the price at which the same good trades in the same period and in the same market is due to the fact that stores that are, on average, equally expensive set persistently different prices for the same good. We refer to this phenomenon as relative price dispersion. We argue that relative price dispersion stems from sellers? attempts to discriminate between high-valuation buyers who need to make all of their purchases in the same store and low-valuation buyers who are ...

Can Intangible Capital Explain Cyclical Movements in the Labor Wedge?
Intangible capital is an important factor of production in modern economies that is generally neglected in business cycle analyses. We demonstrate that intangible capital can have a substantial impact on business cycle dynamics, especially if the intangible is complementary with production capacity. We focus on customer capital: the capital embodied in the relationships a firm has with its customers. Introducing customer capital into a standard real business cycle model generates a volatile and countercyclical labor wedge, due to a mismeasured marginal product of labor. We also provide new ...

Unions in a frictional labor market
Revised May 2016. We analyze a labor market with search and matching frictions in which wage setting is controlled by a monopoly union. Frictions render existing matches a form of firm-specific capital that is subject to a hold-up problem in a unionized labor market. We study how this hold-up problem manifests itself in a dynamic infinite horizon model with fully rational agents. We find that wage solidarity, seemingly an important norm governing union operations, leaves the unionized labor market vulnerable to potentially substantial distortions because of hold-up. Introducing a tenure ...

Is Rising Product Market Concentration a Concerning Sign of Growing Monopoly Power?
Big firms are coming to dominate markets, but that need not imply it’s time for government to step in.

Firm Wages in a Frictional Labor Market
This paper studies a labor market with directed search, where multi-worker firms follow a firm wage policy: They pay equally productive workers the same. The policy reduces wages, due to the influence of firms? existing workers on their wage setting problem, increasing the profitability of hiring. It also introduces a time-inconsistency into the dynamic firm problem, because firms face a less elastic labor supply in the short run. To consider outcomes when firms reoptimize each period, I study Markov perfect equilibria, proposing a tractable solution approach based on standard Euler ...

Price Setting with Customer Capital: Sales, Teasers, and Rigidity
This paper studies price setting in an equilibrium search model of frictional product markets with long-term customer relationships. The theory gives rise to temporary sales when pricing is constrained to be anonymous across a firm’s customer base. Equilibrium prices are inefficiently high, giving rise to overselling and excess trade, and the emergence of sale pricing can improve allocations by limiting this overselling. Pricing is also characterized by an asymmetry involving a stable regular price and variable sale price when firms face idiosyncratic shocks. Absent anonymous pricing, the ...

The Value of Loyal Customers
Is there a rational reason that stock prices in some industries greatly exceed book values? The answer may lie in the idea that customers are capital.
