Macroeconomic dynamics in a model of goods,labor, and credit market frictions

Goods market frictions drastically change the dynamics of the labor market, both in terms of persistence and volatility. In a model with three imperfect markets – goods, labor, and credit – we find that credit and goods market imperfections are substitutable in raising volatility. Goods market frictions are unique in generating persistence. Two key mechanisms in the goods market generate large hump-shaped responses to productivity shocks: countercyclical goods market tightness and prices alter future profit flows and raise persistence; procyclical search effort of consumers and firms raises amplification. Goods market frictions are thus key in understanding labor market dynamics.     

Accounting: a source of market imperfection

Evidence is presented to show that accounting reports do not necessarily represent the position and performince of firms, and that audit reports are ambiguous indicators of the quality of accounting information. As such, contemporary accounting practices contribute to 'imperfection' in the securities market, and hence are likely to lower the efficiency of the securities market in allocating resources to productive uses.

Comparative statics of a two-country capital/money model

This paper presents a two country version of James Tobin's capital/money model, with international trade and capital transactions. The model is used to derive comparative static properties of financial market equilibrium under four alternative regimes: fixed or flexible exchange rates combined with a pegged foreign government interest rate or a fixed supply of foreign government debt. The comparative static results derived by Tobin for a closed economy, and by William Branson for a small country with an open economy, are preserved in the model developed here only in the case where both the exchange rate and the foreign interest rate are pegged. The reasons for this are explored.     

A credit scoring model for Vietnam's retail banking market

As banking markets in developing countries are maturing, banks face competition not only from other domestic banks but also from sophisticated foreign banks. Given the substantial growth of consumer credit and increased regulatory attention to risk management, the development of a well-functioning credit assessment framework is essential. As part of such a framework, we propose a credit scoring model for Vietnamese retail loans. First, we show how to identify those borrower characteristics that should be part of a credit scoring model. Second, we illustrate how such a model can be calibrated to achieve the strategic objectives of the bank. Finally, we assess the use of credit scoring models in the context of transactional versus relationship lending.     

Financial capital movements and central bank behavior in a two-country,short-run portfolio balance model

This paper analyzes financial capital movements in a two-country, short-run, portfolio balance model which includes two securities that are imperfect substitutes. Following a disturbance, equilibrium is, in general, reattained, but the effects on interest rates, money supplies, and international reserve holdings depend on the monetary and reserve asset management policies of the two central banks. Special attention is focused on the case in which one central bank holds its international reserves in the form of ‘key currency’ securities, thereby sterilizing for the ‘key currency’ country. There are several applications of the central result that, for any disturbance, the less changes in international reserves are allowed to affect money supplies, the larger the change in reserves required to reestablish equilibrium.     

Financial liberalization,market structure and credit penetration

This paper shows that the effects of financial liberalization on the credit market of a small and capital constrained economy depend on the market structure of domestic banks prior to liberalization. Specifically, under perfect competition in the domestic credit market prior to liberalization, liberalization leads to lower domestic interest rates, in turn leading to increased credit penetration. However, when the initial market structure is one of imperfect competition, liberalization can lead to the exclusion of less wealthy entrepreneurs from the credit market. This provides a rationale for the mixed empirical evidence concerning the effects of liberalization on access to credit in developing markets. Moreover, the analysis provides new insights into the consequences of foreign lenders’ entry into developing economies.     

Financial market globalization,nonconvergence and credit cycles

This paper explores the dynamic consequences of variable investment-project size in a global economy consisting of many small open countries that are plagued with domestic credit market frictions. As is customary in the literature, borrowers provide some internal funds, but they also need external funds to implement their investment projects, which are subject to the costly-state-verification problem. Contrary to the literature, the investment-project size increases with the country’s own capital stock. We find that financial market globalization may lead to a process of oscillatory convergence, even in the absence of any exogenous shocks, if the investment-project size is very sensitive to the change in capital stock.     

Counterparty credit risk and the credit default swap market

Counterparty credit risk has become one of the highest-profile risks facing participants in the financial markets. Despite this, relatively little is known about how counterparty credit risk is actually priced. We examine this issue using an extensive proprietary data set of contemporaneous CDS transaction prices and quotes by 14 different CDS dealers selling credit protection on the same underlying firm. This unique cross-sectional data set allows us to identify directly how dealers' credit risk affects the prices of these controversial credit derivatives. We find that counterparty credit risk is priced in the CDS market. The magnitude of the effect, however, is vanishingly small and is consistent with a market structure in which participants require collateralization of swap liabilities by counterparties.

Interaction of market and credit risk

Experience during the financial crisis illustrates that the integrated measurement and management of different forms of risk remains a challenge for industry practitioners, researchers and financial supervisors alike. In the context of related literature, this article summarizes new research on the interaction of market and credit risk and implications for risk management that is presented in this special issue. The research covered highlights in particular the errors that can occur in the aggregation of the two types of risk and the strong relationships between them that suggest caution in the use of pragmatic distinctions between them. The article also touches on some research-based lessons for supervisory policies and suggests some directions for future research.     

Information externalities in the credit market and the spell of credit rationing

We present the first empirical study of loan searching strategies and loan granting decisions in a context where banks observe whether applicants have unsuccessfully applied for credit to other lenders in the past. Our identification strategy benefits from the use of granular data on loan applications and exploits the fact that evaluating lenders observe only the rejections received by a borrower up to six months before the current application. We document that past rejections diminish the probability of approval and increase the probability that a loan search is interrupted.     

Changes in volatility of credit spread and market efficiency during rapid growth of credit-related securities

This paper investigates the changes in credit spread volatility during 1993–2001. We find that the credit spreads between junk-grade corporate bonds and Treasury bonds were significantly more volatile in the second half of this period when credit-related securities became popular. In contrast, investment-grade bonds exhibited no significant change in volatility. The junk bonds variance ratios changed from being less than one to greater than one. Using the GJR-Garch model, the conditional volatilities of junk bonds increased in the second half of the period and the mean reversion speeds slowed, suggesting a longer time for mean reversion to occur. Our analysis rules out treasury volatility, credit spread level, equity market return, T-bill rate, curvature of the Treasury curve, financial crisis, quantity of defaults and standard deviation of defaults as explanations for the increase in junk bond volatility. In contrast, volatility of equity returns provides a partial explanation of junk bond spread volatility in the later period.     

Product market competition and credit risk

This study theoretically and empirically investigates effects of product market competition on credit risk. We first develop a real-options-based structural model in a homogeneous oligopoly and show that credit spreads are positively related to the number of firms in an industry. The disparity of firm size in an industry is relevant to both product market competition and credit risk, and we therefore extend the model to an asymmetric duopoly case. In particular, we demonstrate that credit spreads of relatively small (large) firms within an industry are positively (negatively) related to Herfindahl-Hirschman index, and the relative firm size in an industry is an important determinant of credit risk. The models’ implications are empirically scrutinized by a reduced-form hazard model and generally supported. By performing out-of-sample analyses, the results demonstrate that firm size together with the interaction terms between intra-industry firm size dummies and competition intensity can effectively predict default.     

Public inputs and the credit market

This paper studies the impact of public goods provision in an adverse selection environment. Public inputs used collectively by firms have indirect spillovers in imperfect credit markets by affecting the random returns of borrowers in this market. Public inputs change the nature of the binding incentive constraint and mitigate distortions in the credit market. The magnitude of such indirect benefits depends upon the ‘type’ of the public input being considered. Public inputs targeted to benefit the less-efficient borrowers in the economy have greater indirect benefits as compared to pure public inputs that benefit all. These additional efficiency gains, emerging out of information-asymmetries in the credit market, should be considered in the cost-benefit analysis of such public inputs.

The good,the bad and the impaired: A credit risk model of the Irish mortgage market

Using a uniquely constructed loan-level dataset of the residential mortgage book of Irish financial institutions, this paper provides a framework for estimating default probabilities of individual mortgages. In contrast to the popular stock delinquency approach, this model provides estimates of default and cure flows: a requirement of the stress test approach adopted by the European Central Bank's comprehensive assessment. In addition, both default and cure transitions are modelled as functions of micro- and macro-covariates including loan characteristics and current macroeconomic conditions such as house prices and unemployment. When comparing the competing equity and affordability effects, labour market deterioration played a stronger role than house equity in the rise of Irish default rates. For cures, a scarring effect of default is identified and estimated with the probability of a loan returning to performing reducing by almost four per cent each month a loan remains delinquent.     

Stock return expectations in the credit market

In this paper we compute long-term stock return expectations (across the business cycle) for individual firms using information backed out from the credit derivatives market. Our methodology builds on previous theoretical results in the literature on stock return expectations and, empirically, we demonstrate a close relationship between credit-implied stock return expectations and future realized stock returns. We also find stock portfolios selected based on credit-implied stock return forecasts to beat equally- and value-weighted portfolios of the same stocks out-of-sample. Contrary to many other studies, our expectations/predictions are made at the individual stock level rather than at the portfolio level, and no parameter estimations using historical stock price- or credit spread observations are needed.     

Stock markets,credit markets,and technology-led growth

The high-tech sector accounts for the majority of corporate innovation in modern economies. In a sample of 38 countries, we document a strong positive relation between the initial size of the country's high-tech sector and subsequent rates of GDP and total factor productivity growth. We also find a strong positive connection between a country's equity (but not credit) market development and the size of its high-tech sector. Our main difference-in-differences estimates show that better developed stock markets support faster growth of innovative-intensive, high-tech industries. The main channels for this effect are higher rates of productivity and faster growth in the number of new high-tech firms. Credit market development fosters growth in industries that rely on external finance for physical capital accumulation but is unimportant for growth in innovation-intensive industries. These findings show that stock markets and credit markets play important but distinct roles in supporting economic growth. Stock markets are uniquely suited for financing technology-led growth, a particularly important concern for advanced economies.
