Does an increase in competition increase or decrease bank stability? I use a novel way to capture changes in banking competition by exploring how the exogenous state-specific process of banking deregulation gradually lowered entry barriers into urban banking markets. I find that the increase in market contestability significantly improves bank stability. This result is robust to the inclusion of additional fixed effects and other influences, such as mergers and acquisitions, or geographic expansion. Moreover, I find that greater competition reduces banks’ failure probability, share of non-performing loans and increases profitability. These findings suggest that competition increases stability, as it improves bank profitability and asset quality.

This paper studies the use of cash and credit for making transactions when there is asymmetric information in credit markets. For relatively low inflation rates, equilibria are of the pooling variety and low-credit-risk consumers signal their riskiness to lenders only indirectly by establishing a good track record in credit markets. For higher inflation rates there may exist a separating equilibrium in which low-credit-risk consumers directly signal their type to lenders by specializing in cash early in life and specializing in credit later in life. The greater the degree of adverse selection in credit markets, the wider the range of inflation rates for which a separating equilibrium exists. Credit usage is increasing in the inflation rate, but greater adverse selection may increase or decrease credit usage depending on the parameterization.

Diversification by banks affects the systemic risk of the sector. Importantly, Wagner (2010) shows that linear diversification increases systemic risk. We consider the case of securitization, whereby loan portfolios are sliced into tranches with different seniority levels. We show that tranching offers nonlinear diversification strategies, which can reduce the failure risk of individual institutions beyond the minimum level attainable by linear diversification without increasing systemic risk.

The most recently issued, on-the-run, Treasuries are extremely liquid and frequently trade at a premium in both the cash and repo, or financing, markets. Previous research suggests that both the cash and repo premiums reflect demand from buy-and-hold investors who value the superior liquidity of these securities and are reluctant to lend them in the repo market. We find evidence that premiums in the repo market are also closely related to market participants’ demand to hedge interest rate risk associated with their holdings of fixed income securities.

Of key importance in the governance structure of firms is the role of financial incentives for each major player. The main contribution of this article is an analysis of how an insider's concentration of wealth in his or her bank investment affects incentives to take risk. Major empirical findings are that, first, bank earnings variation falls when bank managers have more of their wealth concentrated in their banks; second, hired-manager banks become less risky when a person who has significant motivation to monitor bank management has his or her wealth highly concentrated in the bank; and third, stock ownership by hired managers can increase total risk of a bank. Further analysis suggests that community banks in our sample control earnings variation by manipulating idiosyncratic risk, credit risk, and leverage but not systematic risk or the loan-to-asset ratio.

Using a unique set of banking data containing both originally-reported and subsequently-revised financial variables, we study accounting restatements. Our results indicate the worse a bank's financial condition, the more likely it is for originally-reported data to understate financial losses. Also, we find supervisory exams have an important role in uncovering financial problems and prompting accounting restatements to correct loss underreporting. While revisions are directly related to financial difficulties, exam-based restatements are evident at even the earliest stages of deterioration, indicating substantial accounting misstatements—at both banks and other types of companies—can occur well outside severe business circumstances.

This paper investigates the once and future role of listing fees. We consider the theory of listing fees and why such a pricing structure initially evolved. We show how capital market developments have changed the desirability, and even viability, of this pricing structure. We then analyze the economics of listing fees. While providing revenue to the exchange, listing fees impose large (opportunity) costs, and we analyze this trade-off, presenting evidence from the New York Stock Exchange. We also discuss what types of listing requirements make economics sense for exchanges (or perhaps regulators) to impose on companies. Finally we consider whether listing fees will continue to survive. Journal of Economic Literature Classification Numbers: G10, G18, K22, K23.

This paper reviews and analyzes the legal and economic aspects of the duty of best execution. Although a well-established principle of securities trading, we show that the dual problems of definition and enforcement make best execution both unwieldy and unworkable as a mandated legal duty. We examine the impact of several market practices on best execution, in particular payment for order flow, preferencing and internalization practices, and price improvement and order execution protocols. We suggest three possible directions for the future rule and interpretation of the duty of best execution.Journal of Economic LiteratureClassification Numbers: G10, G18, K22, K23.

This paper analyzes dual trading on futures contracts restricted by Chicago Mercantile Exchange Rule 552. Using floor trader data, several categories of traders are identified, and differences in strategies and profitability are examined. When unrestricted, dual traders execute most customer orders and few personal trades. The evidence supports the hypothesis that dual traders are superior brokers. However, there is no evidence of informational advantages in dual traders' personal trading. Dual traders are shown to provide liquidity with their personal trades. Finally, Rule 552 does not appear to have increased trading costs.Journal of Economic LiteratureClassification Numbers: G12, G13, D82.

Bank runs in the literature take the form of withdrawals of demand deposits payable in real goods, which deplete a fixed reserve of goods in the banking system. That framework describes traditional bank runs based on currency withdrawals as occurred historically in the US and more recently in developing countries. However, in a modern banking system, large withdrawals typically take the form of electronic payments of inside money, with no analog of a depletion of a scarce reserve from the banking system. In a new framework of nominal demand deposits repayable in inside money, pure liquidity-driven bank runs do not occur. If there were excessive early withdrawals, nominal deposits would hedge the bank and flexible monetary prices in the goods market would limit real consumption. The maturity mismatch of short term liabilities and long term assets is not sufficient for multiple equilibria bank runs without other frictions. A key role of the bank is to ensure optimal real liquidity, which allows markets to optimally distribute consumption goods through the price mechanism.
