Recent studies show that uncertainty shocks have quantitatively important effects on the real economy. This paper examines one particular channel at work: the supply of credit. It presents a model in which a bank, even if managed by risk-neutral shareholders and subject to limited liability, can exhibit self-insurance, and thus loan supply contracts when uncertainty increases. This prediction is tested with the universe of U.S. commercial banks over the period 1984-2010. Identification of credit supply is achieved by looking at the differential response of banks according to their level of capitalization. Consistent with the theoretical predictions, increases in uncertainty reduce the supply of credit, more so for banks with lower levels of capitalization. These results are weaker for large banks, and are robust to controlling for the lending and capital channels of monetary policy, to different measures of uncertainty, and to breaking the dataset in subsamples. Quantitatively, uncertainty shocks are almost as important as monetary policy ones with regards to the effects on the supply of credit.

We study the impact of bank credit on firm productivity. We exploit a matched firm-bank database covering all the credit relationships of Italian corporations, together with a natural experiment, to measure idiosyncratic supply-side shocks to credit availability and to estimate a production model augmented with financial frictions. We find that a contraction in credit supply causes a reduction of firm TFP growth and also harms IT-adoption, innovation, exporting, and adoption of superior management practices, while a credit expansion has limited impact. Quantitatively, the credit contraction between 2007 and 2009 accounts for about a quarter of observed the decline in TFP.

Bank Liquidity Creation and Financial Crises delivers a consistent, logical presentation of bank liquidity creation and addresses questions of research and policy interest that can be easily understood by readers with no advanced or specialized industry knowledge. Authors Allen Berger and Christa Bouwman examine ways to measure bank liquidity creation, how much liquidity banks create in different countries, the effects of monetary policy (including interest rate policy, lender of last resort, and quantitative easing), the effects of capital, the effects of regulatory interventions, the effects of bailouts, and much more. They also analyze bank liquidity creation in the US over the past three decades during both normal times and financial crises. Narrowing the gap between the "academic world" (focused on theories) and the "practitioner world" (dedicated to solving real-world problems), this book is a helpful new tool for evaluating a bank's performance over time and comparing it to its peer group. - Explains that bank liquidity creation is a more comprehensive measure of a bank's output than traditional measures and can also be used to measure bank liquidity - Describes how high levels of bank liquidity creation may cause or predict future financial crises - Addresses questions of research and policy interest related to bank liquidity creation around the world and provides links to websites with data and other materials to address these questions - Includes such hot-button topics as the effects of monetary policy (including interest rate policy, lender of last resort, and quantitative easing), the effects of capital, the effects of regulatory interventions, and the effects of bailouts

In The Economics of Inaction, leading economist Nancy Stokey shows how the tools of stochastic control can be applied to dynamic problems of decision making under uncertainty when fixed costs are present. Stokey provides a self-contained, rigorous, and clear treatment of two types of models, impulse and instantaneous control. She presents the relevant results about Brownian motion and other diffusion processes, develops methods for analyzing each type of problem, and discusses applications to price setting, investment, and durable goods purchases."--Pub. desc.

We analyze holdings of public bonds by over 20,000 banks in 191 countries, and the role of these bonds in 20 sovereign defaults over 1998-2012. Banks hold many public bonds (on average 9% of their assets), particularly in less financially-developed countries. During sovereign defaults, banks increase their exposure to public bonds, especially large banks and when expected bond returns are high. At the bank level, bondholdings correlate negatively with subsequent lending during sovereign defaults. This correlation is mostly due to bonds acquired in pre-default years. These findings shed light on alternative theories of the sovereign default-banking crisis nexus.

Consumer Credit and the American Economy examines the economics, behavioral science, sociology, history, institutions, law, and regulation of consumer credit in the United States. After discussing the origins and various kinds of consumer credit available in today's marketplace, this book reviews at some length the long run growth of consumer credit to explore the widely held belief that somehow consumer credit has risen "too fast for too long." It then turns to demand and supply with chapters discussing neoclassical theories of demand, new behavioral economics, and evidence on production costs and why consumer credit might seem expensive compared to some other kinds of credit like government finance. This discussion includes review of the economics of risk management and funding sources, as well discussion of the economic theory of why some people might be limited in their credit search, the phenomenon of credit rationing. This examination includes review of issues of risk management through mathematical methods of borrower screening known as credit scoring and financial market sources of funding for offerings of consumer credit. The book then discusses technological change in credit granting. It examines how modern automated information systems called credit reporting agencies, or more popularly "credit bureaus," reduce the costs of information acquisition and permit greater credit availability at less cost. This discussion is followed by examination of the logical offspring of technology, the ubiquitous credit card that permits consumers access to both payments and credit services worldwide virtually instantly. After a chapter on institutions that have arisen to supply credit to individuals for whom mainstream credit is often unavailable, including "payday loans" and other small dollar sources of loans, discussion turns to legal structure and the regulation of consumer credit. There are separate chapters on the theories behind the two main thrusts of federal regulation to this point, fairness for all and financial disclosure. Following these chapters, there is another on state regulation that has long focused on marketplace access and pricing. Before a final concluding chapter, another chapter focuses on two noncredit marketplace products that are closely related to credit. The first of them, debt protection including credit insurance and other forms of credit protection, is economically a complement. The second product, consumer leasing, is a substitute for credit use in many situations, especially involving acquisition of automobiles. This chapter is followed by a full review of consumer bankruptcy, what happens in the worst of cases when consumers find themselves unable to repay their loans. Because of the importance of consumer credit in consumers' financial affairs, the intended audience includes anyone interested in these issues, not only specialists who spend much of their time focused on them. For this reason, the authors have carefully avoided academic jargon and the mathematics that is the modern language of economics. It also examines the psychological, sociological, historical, and especially legal traditions that go into fully understanding what has led to the demand for consumer credit and to what the markets and institutions that provide these products have become today.

In this volume, specialists from traditionally separate areas in economics and finance investigate issues at the conjunction of their fields. They argue that financial decisions of the firm can affect real economic activity—and this is true for enough firms and consumers to have significant aggregate economic effects. They demonstrate that important differences—asymmetries—in access to information between "borrowers" and "lenders" ("insiders" and "outsiders") in financial transactions affect investment decisions of firms and the organization of financial markets. The original research emphasizes the role of information problems in explaining empirically important links between internal finance and investment, as well as their role in accounting for observed variations in mechanisms for corporate control.
