Working Paper
Intermediation in Markets for Goods and Markets for Assets

We analyze agents' decisions to act as producers or intermediaries using equilibrium search theory. Extending previous analyses in various ways, we ask when intermediation emerges and study its efficiency. In one version of the framework, meant to resemble retail, middlemen hold goods, which entails (storage) costs; that model always displays uniqueness and simple transition dynamics. In another version, middlemen hold assets, which entails negative costs, that is, positive returns; that model can have multiple equilibria and complicated belief-based dynamics. These results are consistent ...

Firms as Learning Environments: Implications for Earnings Dynamics and Job Search

This paper demonstrates that heterogeneity in firms’ promotion of human capital accumulation is an important determinant of life-cycle earnings inequality. I use administrative micro data from Germany to show that different establishments offer systematically different earnings growth rates for their workers. This observation suggests that that the increase in inequality over the life cycle reflects not only inherent worker variation, but also differences in the firms that workers happen to match with over their lifetimes. To quantify this channel, I develop a life-cycle search model with ...

Payment networks in a search model of money

In a simple search model of money, we study a special kind of memory that gives rise to an arrangement resembling a payment network. Specifically, we assume that agents can pay a cost to access a central database that tracks payments made and received. Incentives must be provided to agents to access the central database and to produce when they participate in this arrangement. We also study policies that can loosen these incentive constraints. In particular, we show that a "no-surcharge" rule has good incentive properties. Finally, we compare our model with that of Cavalcanti and Wallace.

Discussion Paper
When Do Trade Frictions Increase Liquidity?

Economists tend to assume that frictions that limit trading in financial markets reduce liquidity and lower investor welfare. In this blog I discuss a recent staff study of mine that challenges that conventional wisdom. I explain how introducing trading frictions—such as circuit breakers—that slow or halt trading in an over-the-counter market experiencing a fire sale might, paradoxically, lead to higher liquidity and investor welfare.

Working Paper
Using the Eye of the Storm to Predict the Wave of Covid-19 UI Claims

We leverage an event-study research design focused on the seven costliest hurricanes to hit the US mainland since 2004 to identify the elasticity of unemployment insurance filings with respect to search intensity. Applying our elasticity estimate to the state-level Google Trends indexes for the topic “unemployment,” we show that out-of-sample forecasts made ahead of the official data releases for March 21 and 28 predicted to a large degree the extent of the Covid-19 related surge in the demand for unemployment insurance. In addition, we provide a robust assessment of the uncertainty ...

More on Middlemen: Equilibrium Entry and Efficiency in Intermediated Markets

This paper generalizes Rubinstein and Wolinsky?s model of middlemen (intermediation) by incorporating production and search costs, plus more general matching and bargaining. This allows us to study many new issues, including entry, efficiency and dynamics. In the benchmark model, equilibrium exists uniquely, and involves production and intermediation for some parameters but not others. Sometimes intermediation is essential: the market operates iff middlemen are active. If bargaining powers are set correctly equilibrium is efficient; if not there can be too much or too little economic ...

Trade dynamics in the market for federal funds

We use minute-by-minute daily transaction-level payments data to document the cross-sectional and time-series behavior of the estimated prices and quantities negotiated by commercial banks in the interbank market. We study the frequency and volume of trade, the size distribution of loans, the distribution of bilateral rates, and the intraday dynamics of the reserve balances held by commercial banks. We find evidence of the importance of the liquidity provision achieved by commercial banks that act as de facto intermediaries of funds.

Unemployment Benefits and Unemployment in the Great Recession: The Role of Equilibrium Effects

Equilibrium labor market theory suggests that unemployment benefit extensions affect unemployment by impacting both job search decisions by the unemployed and job creation decisions by employers. The existing empirical literature focused on the former effect only. We develop a new methodology necessary to incorporate the measurement of the latter effect. Implementing this methodology in the data, we find that benefit extensions raise equilibrium wages and lead to a sharp contraction in vacancy creation and employment and a rise in unemployment.
