We propose a new theory of price rigidity based on firms' Knightian uncertainty about their competitive environment. This uncertainty has two key implications. First, firms learn about the shape of their demand function from past observations of quantities sold. This learning gives rise to kinks...

In this paper we consider the conditions under which instrumental variables methods are required in estimating a hedonic price function and its accompanying demand and supply relations. We assume simple functional forms that permit an explicit solution for the equilibrium hedonic price function....

We study a new data set of US sports card conventions in order to evaluate the pricing theory of two-sided markets. Conventions are two-sided because organizers must set fees to attract both consumers and dealers. We have detailed information on consumer price, dealer price and, since most...

Recent empirical work suggests that small price changes are relatively common. This evidence has been used to criticize classic menu-cost models. In this paper, we use scanner data from a national supermarket chain and micro data from the Consumer Price Index to reassess the importance of small...

This paper tests the empirical importance of the price dispersion predictions of the Prescott-Eden-Dana (PED) models. Equilibrium price dispersion is derived in a setting with costly capacity and demand uncertainty where different fares can be explained by the different selling probabilities....

We assess the importance of nominal rigidities using a new weekly scanner data set. We find that nominal rigidities are important but do not take the form of sticky prices. Instead, they take the form of inertia in reference prices and costs, defined as the most common prices and costs within a...

How should a firm price a new product for which little is known about demand? We propose a simple pricing rule: the firm only estimates the maximum price it can charge and still expect to sell at least some units, and then sets price as though the actual demand curve were linear. We show that if...

A model is provided whereby a monopolist firm chooses to price its product at zero. This outcome is shown to be driven by the assumption of ‘free disposal' alongside selection markets (where prices impact on a firm's costs). Free disposal creates a mass point of consumers whose utility from...

Pecuniary externalities have regained the interest of researchers as they seek policy interventions and regulations to remedy externality-induced distortions, e.g., balance sheet effects, amplifiers and fire sales. In this paper we go back to first principles and show how to design financial...

The paper studies equilibrium pricing in a product market for an indivisible good where buyers search for sellers. Buyers search sequentially for sellers, but do not meet every seller with the same probability. Specifically, a fraction of the buyers' meetings lead to one particular large seller,...
