Working Paper
Targeted search in matching markets

We propose a parsimonious matching model where people's choice of whom to meet endogenizes the degree of randomness in matching. The analysis highlights the interaction between a productive motive, driven by the surplus attainable in a match, and a strategic motive, driven by reciprocity of interest of potential matches. We find that the interaction between these two motives differs with preferences ? vertical versus horizontal ? and that this interaction implies that preferences estimated using our model can look markedly different from those estimated using a model where the degree of ...

Self-confirming Price Dispersion in Monetary Economies

In a monetary economy, we show that price dispersion arises as an equilibrium outcome without the need for costly simultaneous search or any heterogeneity in preferences, production costs, or search technologies. A distribution of money holdings among buyers makes sellers indifferent across a set of posted prices, leading to a non-degenerate price distribution. This price distribution, in turn, makes buyers indifferent across a range of money balances, rationalizing the non-degenerate distribution of money holdings. We completely characterize the distribution of posted prices and money ...

Trade Dynamics in the Market for Federal Funds

We develop a model of the market for federal funds that explicitly accounts for its two distinctive features: banks have to search for a suitable counterparty, and once they meet, both parties negotiate the size of the loan and the repayment. The theory is used to answer a number of positive and normative questions: What are the determinants of the fed funds rate? How does the market reallocate funds? Is the market able to achieve an efficient reallocation of funds? We also use the model for theoretical and quantitative analyses of policy issues facing modern central banks.

Working Paper
Goods-Market Frictions and International Trade

We present a tractable framework that embeds goods-market frictions in a general equilibrium dynamic model with heterogeneous exporters and identical importers. These frictions arise because it takes time and expense for exporters and importers to meet. We show that search frictions lead to an endogenous fraction of unmatched exporters, alter the gains from trade, endogenize entry costs, and imply that the competitive equilibrium does not generally result in the socially optimal number of searching firms. Finally, ignoring search frictions results in biased estimates of the effect of tariffs ...

Working Paper
Goods-Market Frictions and International Trade

We add goods-market frictions to a general equilibrium dynamic model with heterogeneous exporting producers and identical importing retailers. Our tractable framework leads to endogenously unmatched producers, which attenuate welfare responses to foreign shocks but increase the trade elasticity relative to a model without search costs. Search frictions are quantitatively important in our calibration, attenuating welfare responses to tariffs by 40 percent and increasing the trade elasticity by 50 percent. Eliminating search costs raises welfare by 1 percent and increasing them by only a few ...

Nonlinear Unemployment Effects of the Inflation Tax

We argue that long-run inflation has nonlinear and state-dependent effects on unemployment, output, and welfare. Using panel data from the OECD, we document three correlations. First, there is a positive long-run relationship between anticipated inflation and unemployment. Second, there is also a positive correlation between anticipated inflation and unemployment volatility. Third, the long-run inflation-unemployment relationship is not only positive, but also stronger when unemployment is higher. We show that these correlations arise in a standard monetary search model with two shocks – ...

Working Paper
Capacity Choice, Monetary Trade, and the Cost of Inflation

Firms often make production decisions before meeting a buyer. We incorporate this often-overlooked fact into an otherwise standard monetary search model and show that it has important implications for the set of equilibria, efficiency, and the cost of inflation. Our model features a strategic complementarity between the buyers' ex ante choice of money balances and sellers' ex ante choice of productive capacity. When resale value of unsold inventories is high, sellers carry excess capacity and the equilibrium is unique. But, when resale value is low, there is a continuum of equilibria, all of ...

Search-Based Models of Money and Finance: An Integrated Approach

Many applications of search theory in monetary economics use the Shi-Trejos-Wright model, hereafter STW, while applications in finance use Duffie-Grleanu-Pederson, hereafter DGP. These approaches have much in common, and both claim to be about liquidity, but the models also differ in a fundamental way: in STW agents use assets as payment instruments when trading goods; in DGP there are no gains from exchanging goods, but agents trade because they value assets differently with goods serving as payment instruments. We develop a framework nesting the two. This clarifies the connection between ...
