Liquidity and leverage

In a financial system in which balance sheets are continuously marked to market, asset price changes appear immediately as changes in net worth, and eliciting responses from financial intermediaries who adjust the size of their balance sheets. We document evidence that marked-to-market leverage is strongly procyclical. Such behavior has aggregate consequences. Changes in dealer repos – the primary margin of adjustment for the aggregate balance sheets of intermediaries – forecast changes in financial market risk as measured by the innovations in the Chicago Board Options Exchange Volatility Index VIX index. Aggregate liquidity can be seen as the rate of change of the aggregate balance sheet of the financial intermediaries.     

The long-term effects of bank recapitalization: Evidence from Indonesia

Do government-sponsored bank recapitalization programs spur lending and reduce risk? This paper assesses the impact of Indonesia’s bank recapitalization program on lending and bank risk following the Asian financial crisis of 1997. Using unique bank-level data, difference-in-differences estimates suggest that recapitalization increased lending (and more so for larger banks), but also boosted bank risk in the long term. Results remain robust to considerations of (1) bank-level differences in political connections, business group affiliation, ownership type, and (2) changes in macroeconomic conditions, capital requirements, accounting regulations, and public credit registry availability.     

Financial globalization, financial crises and contagion

Two observations suggest that financial globalization played an important role in the recent financial crisis. First, more than half of the rise in net borrowing of the U.S. non-financial sectors since the mid-1980s has been financed by foreign lending. Second, the collapse of the U.S. housing and mortgage-backed-securities markets had worldwide effects on financial institutions and asset markets. Using an open-economy model where financial intermediaries play a central role, we show that financial integration leads to a sharp rise in net credit in the most financially developed country and to large asset price spillovers of country-specific shocks to bank capital. The impacts of these shocks on asset prices are amplified by bank capital requirements based on mark-to-market.     

Interactions of Corporate Financing and Investment Decisions: A Dynamic Framework

This article analyzes the interaction between a firm's dynamic investment, operating, and financing decisions in a model with operating adjustment and recapitalization costs. Using numerical analysis, we solve the model for cases that highlight interaction effects. We find that higher production flexibility (due to lower costs of shutting down and reopening a production facility) enhances the firm's debt capacity, thereby increasing the net tax shield value of debt financing. While higher financial flexibility (resulting from lower recapitalization costs) has a similar effect, production flexibility and financial flexibility are, to some extent, substitutes. We find that the impact of debt financing on the firm's investment and operating decisions is economically insignificant.     

Resolution of financial distress under agency frictions

We introduce, in a dynamic-contracting framework with moral hazard, the possibility of recapitalization as an alternative to liquidation when a firm is distressed. This is achieved by considering a risk-averse agent and by allowing (but not requiring) the latter to inject additional capital into the firm when necessary. We show that firm recapitalization may arise in an optimal, long-term contract. As a consequence, we find that there are two mechanisms at a firm’s disposal so as to deal with financial difficulties: one corresponds to a recapitalization process, the other to a liquidation one. The choice of mechanism is based on a cost-benefit analysis.     

Diversification disasters

The recent financial crisis has revealed significant externalities and systemic risks that arise from the interconnectedness of financial intermediaries’ risk portfolios. We develop a model in which the negative externality arises because intermediaries’ actions to diversify that are optimal for individual intermediaries may prove to be suboptimal for society. We show that the externality depends critically on the distributional properties of the risks. The optimal social outcome involves less risk-sharing, but also a lower probability for massive collapses of intermediaries. We derive the exact conditions under which risk-sharing restrictions create a socially preferable outcome. Our analysis has implications for regulation of financial institutions and risk management.     

Retracted: Risk Management in Financial Institutions

We study risk management in financial institutions using data on hedging of interest rate and foreign exchange risk. We find strong evidence that institutions with higher net worth hedge more, controlling for risk exposures, across institutions and within institutions over time. For identification, we exploit net worth shocks resulting from loan losses due to declines in house prices. Institutions that sustain such shocks reduce hedging significantly relative to otherwise-similar institutions. The reduction in hedging is differentially larger among institutions with high real estate exposure. The evidence is consistent with the theory that financial constraints impede both financing and hedging.     

A model of unconventional monetary policy

We develop a quantitative monetary DSGE model with financial intermediaries that face endogenously determined balance sheet constraints. We then use the model to evaluate the effects of the central bank using unconventional monetary policy to combat a simulated financial crisis. We interpret unconventional monetary policy as expanding central bank credit intermediation to offset a disruption of private financial intermediation. Within our framework the central bank is less efficient than private intermediaries at making loans but it has the advantage of being able to elastically obtain funds by issuing riskless government debt. Unlike private intermediaries, it is not balance sheet constrained. During a crisis, the balance sheet constraints on private intermediaries tighten, raising the net benefits from central bank intermediation. These benefits may be substantial even if the zero lower bound constraint on the nominal interest rate is not binding. In the event this constraint is binding, though, these net benefits may be significantly enhanced.     

Liquidity,innovation and growth

Many countries simultaneously suffer from high inflation, low growth and poorly developed financial sectors. In this paper, we integrate a microfounded model of money and finance into a model of endogenous growth to examine the effects of inflation on welfare, growth and the size of the financial sector. A novel feature is that the innovation sector is decentralized. Financial intermediaries arise endogenously to provide liquidity to this sector. Consistent with the data but in contrast to previous work, reducing inflation generates large growth gains. These large gains cannot be easily reproduced by imposing a cash-in-advance constraint in the innovation sector.     

Financial advisor participation rates and low net worth investors

This study presents a simple analytical framework to identify the key determinants underlying the incentives for households to engage financial advisors. Using the US 2007 Survey of Consumer Finances, we employ a logistic regression approach to understand the characteristics of households who engage financial advisors for investment or comprehensive financial advice. We find that age, education, employment category, income and net worth are highly significant variables related to the propensity to engage a financial advisor. The results also indicate significantly reduced active engagement between advisors and low net worth investors than claimed by the low net worth investors in the survey. We construct a model to derive the expected fee profile of financial advisors as a function of wealth and compare the fee structure against a financial advisor client portfolio. We find that a combination of lower aggregate costs per investor and higher expected fee income motivates advisors to target higher net worth investors. Advisors therefore prefer higher net worth investors due to the lower aggregate costs of engagement, which drives low investment participation rates by less wealthy households.     

An empirical analysis of differences in Black and White asset and liability combinations☆

This study analyzes data from the 1992 Survey of Consumer Finances and finds significant differences in asset and liability combinations between Black and White households. In addition, White households are identified as having significantly greater net worth and financial assets relative to Black households. We are unable to show that the net worth of Black households is constrained by barriers in financial markets. Our study investigates how this difference in net worth could engender different financing decisions. We find that Black households are significantly more risk averse in their choice of assets. Further, we find that Black households typically pay higher rates for several types of credit instruments, even though they self identify as conducting significantly more extensive searches in the financial markets.

Banks as Tax Planning Intermediaries

We provide the first large‐scale empirical evidence of banks functioning as tax planning intermediaries. We posit that some banks specialize in assisting corporate clients with tax planning. In this role, banks make use of their centrality in financial relationships; access to private information; and ability to structure, execute, and participate in tax planning transactions for clients. We measure bank‐client relationships using loan contracts and measure client tax planning using either the cash effective tax rate or the unrecognized tax benefit balance. Using a difference‐in‐differences design, we find that firms experience meaningful tax reductions when they begin a relationship with a bank whose existing clients engage in above‐median tax planning. The effects of pairing with such tax intermediary banks are concentrated in relationships with larger or longer maturity loans, clients with foreign income or greater credit risk, and when the bank is an industry specialist or has above‐median investment banking activities. Finally, we find that potential clients are more likely to choose tax intermediary banks than nontax intermediary banks, suggesting that tax intermediary banks benefit by attracting new business. Collectively, our results suggest that some banks act as tax planning intermediaries, a role beyond the traditional one of financial intermediary.     

A theoretical model of bank lending: Does ownership matter in times of crisis?

The present study investigates theoretically the lending responses of government-owned and private banks in the event of unexpected financial shocks. Our model predicts that public banks provide more loans to the real sector during times of crisis, compared to private banks which cut down on lending and increase liquidity holdings. We put forth three reasons for this heterogeneous behavior. First, the objective of public banks, in contrast to their private peers, is not only to maximize profits given risks, but also to stabilize and promote the recovery of the economy. Second, public banks may suffer less deposit withdrawals or avoid a bank run in a severe crisis, because the state has better access to additional funds making a recapitalization more likely. And finally, public banks may suffer less deposit withdrawals due to their higher credibility in promising a future recapitalization in the case of a severe crisis.     

Dealing with financial instability under a DSGE modeling approach with banking intermediation: A predictability analysis versus TVP-VARs

In the dynamic stochastic general equilibrium (DSGE) literature there has been an increasing awareness on the role that the banking sector can play in macroeconomic activity. We present a DSGE model with financial intermediation as in Gertler and Karadi (2011). The estimation of shocks and of the structural parameters shows that time-variation should be crucial in any attempted empirical analysis. Since DSGE modelling usually fails to take into account inherent nonlinearities of the economy, we propose a novel time-varying parameter (TVP) state-space estimation method for VAR processes both for homoskedastic and heteroskedastic error structures. We conduct an exhaustive empirical exercise to compare the out-of-sample predictive performance of the estimated DSGE model with that of standard ARs, VARs, Bayesian VARs and TVP-VARs. We find that the TVP-VAR provides the best forecasting performance for the series of GDP and net worth of financial intermediaries for all steps-ahead, while the DSGE model outperforms the other specifications in forecasting inflation and the federal funds rate at shorter horizons.     

Board financial expertise and the capital decisions of US banks

We examine whether increasing financial expertise among independent directors facilitates bank capital decisions that promote financial stability. We find US banks with more financial expert independent directors opt for higher target capital ratios and adjust faster their capital structure when they are below the target. We provide evidence suggesting that our results are driven by the skill-set of these directors that lead to a better understanding of bank risks and access to external recapitalization choices. Our findings are further amplified by an increase in the exposure to losses of financial expert directors and by exogenous increases in regulatory scrutiny.     

Intermediated Investment Management

Intermediaries such as financial advisers serve as an interface between portfolio managers and investors. A large fraction of their compensation is often provided through kickbacks from the portfolio manager. We provide an explanation for the widespread use of intermediaries and kickbacks. Depending on the degree of investor sophistication, kickbacks are used either for price discrimination or aggressive marketing. We explore the effects of these arrangements on fund size, flows, performance, and investor welfare. Kickbacks allow higher management fees to be charged, thereby lowering net returns. Competition among active portfolio managers reduces kickbacks and increases the independence of advisory services.     

Customers and investors: A framework for understanding the evolution of financial institutions

Financial institutions are financed by both investors and customers. Investors expect an appropriate risk-adjusted return for providing financing and risk bearing. Customers, in contrast, provide financing in exchange for specific services, and want the service fulfillment to be free of the intermediary's credit risk. We develop a framework that defines the roles of customers and investors in intermediaries, and use it to build an economic theory that has the following main findings. First, with positive net social surplus in the intermediary-customer relationship, the efficient (first best) contract completely insulates the customer from the intermediary's credit risk, thereby exposing the customer only to the risk inherent in the contract terms. Second, when intermediaries face financing frictions, the second-best contract may expose the customer to some intermediary credit risk, generating “customer contract fulfillment” costs. Third, the efficiency loss associated with these costs in the second best rationalizes government guarantees like deposit insurance even when there is no threat of bank runs. We further discuss the implications of this customer-investor nexus for numerous issues related to the design of contracts between financial intermediaries and their customers, the sharing of risks between them, ex ante efficient institutional design, regulatory practices, and the evolving boundaries between banks and financial markets.     

The Real Effects of Financial Sector Interventions during Crises

We assess the importance of supply‐side credit market frictions by studying the impact of bank recapitalization on firm growth in 50 countries during the recent crisis. Our identification strategy exploits the crisis as a shock to credit supply and combines an exogenous measure of firms’ dependence on external financing with policy interventions aimed at restoring bank capital. We find that the growth of financially dependent firms is disproportionately positively affected by bank recapitalization. This effect is quantitatively important and robust to controlling for other policies. These results provide new evidence of the influence of credit market frictions on economic activity.     

现代金融中介理论视角下的我国金融体系模式选择

现代金融中介理论表明,商业银行等金融中介与经济增长之间存在密切的相关性。金融中介在促进经济增长的同时,也面临着许多复杂问题。本文从现代金融中介理论的视角出发,对银行导向型金融体系与市场导向型金融体系进行了国际比较,并从融资关系、风险管理、信息生产、公司治理等角度进行对比分析,得出在中国现实的环境下中介与市场发挥着不同作用,但金融中介的优势明显。因此,我国应选择以金融中介为主、资本市场为辅的金融体系,并加紧推出金融机构的混业经营模式。     

Financial intermediation and the supply of liquidity

I study the role of financial intermediaries in supplying liquidity to the real economy. Firms hold liquid assets to meet unanticipated expenses. Financial intermediaries supply liquidity by pooling partially liquid assets, but their ability to commit future funds depends on their capital. When liquidity is scarce, there is a positive liquidity premium and investment is inefficiently low. Bank losses raise the liquidity premium and reduce investment. I analyze the optimal supply of public liquidity and find that when private liquidity is scarce the government should issue bonds for their liquidity properties, providing justification for countercyclical budget deficits.
