  1. Remapping the Flow of Funds

    Juliane Begenau, Monika Piazzesi and Martin Schneider

    This article argues that quantitative analysis of credit market positions would benefit tremendously if the additional information about the structure of payment streams were more readily available. Most available data on credit market positions, such as the Flow of Funds Accounts report accounting measures such as book value or fair value. In contrast, most economic analysis views asset positions as random payment streams that are valued by state prices. The latter view typically requires additional information, in particular the maturity or next repricing date of the instrument, the promised interest rate, call or prepayment provisions, and the credit rating of the borrower.

  1. Financial Regulation in a Quantitative Model of the Modern Banking System

    Juliane Begenau and Tim Landvoigt

    How does the shadow banking system respond to changes in the capital regulation of commercial banks? This paper builds a quantitative general equilibrium model with commercial banks and shadow banks to study the unintended consequences of capital requirements. A key feature of our model are defaultable bank liabilities that provide liquidity services to households. The quality of the liquidity services provided by bank liabilities depends on their safety in case of default. Commercial bank debt is fully insured and thus provides full liquidity. However, commercial banks do not internalize the social costs of higher leverage in the form of greater bankruptcy losses (moral hazard), and are subject to a regulatory capital requirement. In contrast, shadow bank liabilities are subject to runs and credit risk and thus typically less liquid compared to commercial banks. Shadow banks endogenously limit their leverage as they internalize its costs. Tightening the commercial banks' capital requirement from the status quo leads to safer commercial banks and more shadow banking activity in the economy. While the safety of the financial system increases, it provides less liquidity. Calibrating the model to data from the Financial Accounts of the U.S., the optimal capital requirement is around 20%.

  2. Firm Selection and Corporate Cash Holdings

    Juliane Begenau and Berardino Palazzo

    The gradual replacement of traditional U.S. public companies by more R&D–intensive firms is key to understanding the secular trend in average cash holdings. Over the last 35 years, an increasing share of R&D–intensive firms has entered the stock market with progressively higher cash balances. This positive entry-effect dominates the negative within-firm effect post IPO. We build a firm industry model with endogenous entry to quantify the importance of two competing selection mechanisms: an increasing share of R&D–intensive firms in the overall economy and more favorable IPO conditions. Only the combination of both mechanisms successfully generates a sizable secular increase.

  3. Banks' Risk Exposures

    Juliane Begenau, Monika Piazzesi and Martin Schneider

    This paper studies U.S. banks' exposure to interest rate and credit risk. We exploit the factor structure in interest rates to represent many bank positions in terms of simple factor portfolios. This approach delivers time varying measures of exposure that are comparable across banks as well as across the business segments of an individual bank. We also propose a strategy to estimate exposure due to interest rate derivatives from regulatory data on notional and fair values together with the history of interest rates. We use the approach to document stylized facts about the recent evolution of bank risk taking.

  4. Capital Requirements, Risk Choice, and Liquidity Provision in a Business Cycle Model

    Juliane Begenau

    This paper develops a quantitative dynamic general equilibrium model in which households' preferences for safe and liquid assets constitute a violation of Modigliani and Miller. I show that the scarcity of these coveted assets created by increased bank capital requirements can reduce overall bank funding costs and increase bank lending. I quantify this mechanism in a two-sector business cycle model featuring a banking sector that provides liquidity and has excessive risk-taking incentives. Under reasonable parametrizations, the marginal benefit of higher capital requirements related to this channel significantly exceeds the marginal cost, indicating that U.S. capital requirements have been suboptimally low.
