Heterogeneity in Decentralized Asset Markets
We study a search and bargaining model of asset markets in which investors? heterogeneous valuations for the asset are drawn from an arbitrary distribution. We present a solution technique that makes the model fully tractable, and allows us to provide a complete characterization of the unique equilibrium, in closed form, both in and out of steady state. Using this characterization, we derive several novel implications that highlight the importance of heterogeneity. In particular, we show how some investors endogenously emerge as intermediaries, even though they have no advantage in contacting ...

Macroeconomic Implications of Uniform Pricing
We compile a new database of grocery prices in Argentina, with over 9 million observations per day. We find uniform pricing both within and across regions?i.e., product prices almost do not vary within stores of a chain. Uniform pricing implies that prices would not change with regional conditions or shocks, particularly so if chains operate in several regions. We confirm this hypothesis using employment data. While prices in stores of chains operating almost exclusively in one region do react to changes in regional employment, stores of chains that operate in many regions do not seem to ...

Macroeconomic Implications of Uniform Pricing
We compile a new database of grocery prices in Argentina. We find uniform pricing both within and across regions—i.e., prices almost do not vary within stores of a chain. In line with uniform pricing, prices in stores of chains operating in one region react to changes in regional employment, while prices in multi-region chains do not. Using a quantitative regional model with multi-region firms and uniform pricing, we find a one-half smaller elasticity of prices to a regional than an aggregate shock. This result highlights that some caution may be necessary when using regional shocks to ...

Uniform Pricing Within and Across Regions: New Evidence from Argentina
We compile a new database of grocery prices in Argentina, with over 9 million observations per day. Our main novel inding is that product prices almost do not vary within stores of a chain (i.e., uniform pricing). We also find that prices do not change significantly with regional conditions or shocks, particularly so for chains that operate in many regions. To study the impact of uniform pricing on both consumers and firms, this paper uses a tractable model based on the trade literature. Motivated by our empirical findings, each firm has to set the same price in both regions. Relative to a ...

Paying Too Much? Price Dispersion in the U.S. Mortgage Market
We document wide dispersion in the mortgage rates that households pay on identical loans, and show that borrowers' financial sophistication is an important determinant of the rates obtained. We estimate a gap between the 10th and 90th percentile mortgage rate that borrowers with the same characteristics obtain for identical loans, in the same market, on the same day, of 54 basis points|equivalent to about $6,500 in upfront costs (points) for the average loan. Time-invariant lender attributes explain little of this rate dispersion, and considerable dispersion remains even within loan officer. ...

Large and Small Sellers: A Theory of Equilibrium Price Dispersion with Sequential Search
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, while the remaining meetings lead to one of a continuum of small sellers. In this environment, the small sellers would like to set a price that makes the buyers indifferent between purchasing the good and searching for another seller. The large seller would like to price the small sellers out of the ...

Paying Too Much? Borrower Sophistication and Overpayment in the US Mortgage Market
Comparing mortgage rates that borrowers obtain to rates that lenders could offer for the same loan, we find that many homeowners significantly overpay for their mortgage, with overpayment varying across borrower types and with market interest rates. Survey data reveal that borrowers’ mortgage knowledge and shopping behavior strongly correlate with the rates they secure. We also document substantial variation in how expensive and profitable lenders are, without any evidence that expensive loans are associated with a better borrower experience. Despite many lenders operating in the US ...

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 ...
