Mixed Signals: Investment Distortions with Adverse Selection
We study how adverse selection distorts equilibrium investment allocations in a Walrasian credit market with two-sided heterogeneity. Representative investor and partial equilibrium economies are special cases where investment allocations are distorted above perfect information allocations. By contrast, the general setting features a pecuniary externality that leads to trade and investment allocations below perfect information levels. The degree of heterogeneity between informed agents' type governs the direction of the distortion. Moreover, contracts that complete markets dampen the impact ...

Uncertain booms and fragility
I develop a framework of the buildup and outbreak of financial crises in an asymmetric information setting. In equilibrium, two distinct economic states arise endogenously: ?normal times,? periods of modest investment, and ?booms,? periods of expansionary investment. Normal times occur when the intermediary sector realizes moderate investment opportunities. Booms occur when the intermediary sector realizes many investment opportunities, but also occur when it realizes very few opportunities. As a result, investors face greater uncertainty in booms. During a boom, subsequent arrival of ...

Moldy Lemons and Market Shutdowns
This paper studies competitive market shutdowns due to adverse selection, where sellers post nonexclusive menus of contracts. We first show that the presence of the worst type of agents (moldy lemons) causes markets to fail only if their mass is sufficiently large. We then show that a small mass of moldy lemons can lead to a large cascade of exits when buyers possess outside options. Our results suggest a parsimonious way of generating sudden market shutdowns without relying on institutional details or imposing additional structure on the model. Thus, the simple insights on the properties of ...

Consumer Credit Reporting Data
Since the 2000s, economists across fields have increasingly used consumer credit reporting data for research. We introduce readers to the economics of and the institutional details of these data. Using examples from the literature, we provide practical guidance on how to use these data to construct economic measures of borrowing, consumption, credit access, financial distress, and geographic mobility. We explain what credit scores measure, and why. We highlight how researchers can access credit reporting data via existing datasets or by creating new datasets, including by linking credit ...

Optimal Design of Tokenized Markets
Trades in today’s financial system are inherently subject to settlement uncertainty. This paper explores tokenization as a potential technological solution. A token system, by enabling programmability of assets, can be designed to eradicate settlement uncertainty. We study the allocations achieved in a decentralized market with either the legacy settlement system or a token system. Tokenization can improve efficiency in markets subject to a limited commitment problem. However, it also materially alters the information environment, which in turn aggravates a hold-up problem. This limits ...

Employment Dynamics in a Signaling Model with Workers' Incentives
Many firms adjust employment in a "lumpy" manner -- infrequently and in large bursts. In this paper, I show that lumpy adjustments can arise from concerns about the incentives of remaining workers. Specifically, I develop a model in which a firm's productivity depends on its workers' effort and workers' income prospects depend on the firm's profitability. I use this model to analyze the consequences of demand shocks that are observed by the firm but not by its workers, who can only try to infer the firm's profitability from its employment decisions. I show that the resulting signaling model ...

Specialization in Banking
Using highly detailed data on the loan portfolios of large U.S. banks, we document that these banks "specialize" by concentrating their lending disproportionately into one industry. This specialization improves a bank’s industry-specific knowledge and allows it to offer generous loan terms to borrowers, especially to firms with access to alternate sources of funding and during periods of greater nonbank lending. Superior industry-specific knowledge is further reflected in better loan and, ultimately, bank performance. Banks concentrate more on their primary industry in times of instability ...

Banks, Non Banks, and Lending Standards
We study how competition between banks and non-banks affects lending standards. Banks have private information about some borrowers and are subject to capital requirements to mitigate risk-taking incentives from deposit insurance. Non-banks are uninformed and market forces determine their capital structure. We show that lending standards monotonically increase in bank capital requirements. Intuitively, higher capital requirements raise banks’ skin in the game and screening out bad projects assures positive expected lending returns. Non-banks enter the market when capital requirements are ...

Crisis Chronicles: The Panic of 1825 and the Most Fantastic Financial Swindle of All Time
Centered in London, the banking panic of 1825 has been called the first modern financial crisis, the first Latin American crisis, and the first emerging market crisis. And while the panic displayed many of the key elements of past crises we have covered?fluctuations in money growth, an investment bubble, a stock market crash, and bank runs?this crisis had its own twists, including a Bank of England that hesitated before stepping in as lender of last resort. But it is perhaps best known for an infamous bond market swindle surrounding an entirely made-up Central American principality. In this ...
