International business: determinants of interbank activities

This paper investigates the determinants of the international interbank market, a significant component of international trade in financial services. The sample encompasses both monthly and quarterly data from 1983 to 1993. The superiority of the monthly results suggest that the interbank market should be modelled within a short-term framework. This data interval captures the short-term movement of funds between currencies, Eurobonds, the nonbank market and the domestic banking market by banks to maximize returns. Moreover, the interbank market does not necessarily move in line with fundamental trade and income variables. Rather, the market is sensitive to return differentials, the relative cost of capital, the yield curve and international nonbank assets. The empirical results also indicate that nationality remains important in interbank trading because of the advantages it imparts on the home country in dealing in its home currency, particularly if that currency is a vehicle currency.     

Welfare implications of the transition to high household debt

Aggressive deregulation of the mortgage market in the early 1980s triggered innovations that greatly reduced indebted households’ required home equity, and a borrowing surge followed. This paper uses a calibrated general equilibrium model of lending from the wealthy to the middle class to evaluate the welfare effects of this reform quantitatively. We find that the “indirect” effects of endogenous interest rate and other relative price changes dominate the “direct” effect of relaxing the constraint. The borrowing household's welfare falls even though the reform directly relaxes a constraint on its trade. The saving household's welfare rises substantially.     

Valuation impact of currency crises: Evidence from the ADR market

This study analyzes American depository receipts (ADR) performance surrounding the outbreak of major currency crises during the past decade. By employing event-study methodologies and multifactor pricing models, we find that the outbreak of a currency crisis is accompanied by a negatively significant abnormal return for the corresponding ADRs, even after controlling for variations in exchange rates. We also find significant upward shifts in the exchange rate exposure of ADRs when the home currency is switched from a “pegging” to a “floating” exchange rate regime. In addition, ADR-originating firms with larger sizes, greater proportions of U.S. market activities, and greater market liquidity have relatively less negative abnormal returns (ARs) and less significant upward shifts in currency exposure, implying that such firms are relatively better hedged against currency crises.     

Locals, foreigners, and multi-market trading of equities: Intraday evidence from Thailand

We study stock market orders and trades in a developing country, Thailand, where foreign ownership limits partially segment local and foreign investors into two distinct markets. Some foreigners forgo voting rights and distributions to trade on the “local board”, while some locals forgo such benefits and pay a price premium to trade on the “foreign board”. Regardless of nationality, these cross-market traders typically submit orders when liquidity is high, fill orders at relatively beneficial prices, exploit patterns in stock prices across markets, display profitable holding-period returns, and enhance price discovery. This suggests that skilled, informed trading that affects market quality does not depend on trader nationality.     

Why do people save in cash? Distrust,memories of banking crises,weak institutions and dollarization

The paper analyzes why households hold sizeable shares of their assets in cash at home rather than at banks – a phenomenon that is widespread in many economies but for which information is scarce. Using survey data from ten Central, Eastern and Southeastern European countries, I document the relevance of this behavior and show that cash preferences cannot be fully explained by whether people are banked or unbanked. The analysis reveals that a lack of trust in banks, memories of past banking crises and weak tax enforcement are important factors. Moreover, cash preferences are stronger in dollarized economies where a “safe” foreign currency serves as a store of value.     

Foreign bank entry,credit allocation and lending rates in emerging markets: Empirical evidence from Poland

Earlier studies have documented that foreign banks charge lower lending rates and interest spreads than domestic banks. We hypothesize that this may stem from the superior efficiency of foreign entrants that they decide to pass onto borrowers (“performance hypothesis”), but could also reflect a different loan allocation with respect to borrower transparency, loan maturity and currency (“portfolio composition hypothesis”). We are able to differentiate between the above hypotheses thanks to a novel dataset containing detailed bank-specific information for the Polish banking industry. Our findings demonstrate that banks differ significantly in terms of portfolio composition and we attest to the “portfolio composition hypothesis” by showing that, having controlled for portfolio composition, there are no differences in lending rates between banks.     

Can an Asia Pacific Community,similar to the European Community,emerge?

The purpose of this paper is to analyse whether the Asia Pacific region could form a union similar to the one now established in Europe. To this end, it analyses some of the major challenge faced by the US prior to its union in the 19th century and the way countries such as France and Germany contributed to the formation of the EU, despite their past animosity. The paper proposed a two tier system for the emergence of a union in the Asia Pacific region in which all countries could become part of a regional framework for regional security and free trade and some of the more advanced countries in the region could start the process of financial integration and invite other member countries to join them over time. The paper argues that in the 2st century, unlike the claim of the “currency optimum theory,” there is no need for labour mobility amongst Asian countries for the formation of a union in this region and hence Australia should not expect millions of workers from China to migrate there. The paper argues that the role of Japan and China in the process of regional integration has been underestimated, due to the claim that the former is a monoculture and the latter is too nationalistic. The paper highlights how diversity in the region could be seen as a strength in the Asia Pacific region. It also shows how the process of globalisation has already overcome differences in culture, religion and race which used to be stumbling blocks for more regional or global integration. The paper argues that a union in the Asia Pacific region would reduce “home bias” for international capital flows and hence there would be significant financial transformation of countries in this region.     

Federal Reserve financial crisis lending programs and bank stock returns

We use an E-GARCH model to estimate the wealth effects of Federal Reserve lending during the financial crisis to Investment banks (I-Banks), “Too Big to Fail” (TBTF) banks, and “traditional” commercial banks. Borrowing from the Term Auction Facility program has negative wealth effects for all banks and I-banks in particular. We also find that the market view of the liquidity programs changed across the sample sub-periods. I-Bank and TBTF bank borrowing from the discount window is initially viewed positively, however continued use of the discount window and the Term Auction Facility was generally (though not universally) viewed negatively. Commercial Paper Funding Facility program participation is consistently positive only for traditional banks and programs that focus on the purchase of specific securities (e.g., commercial paper) to address specific problems also appear to primarily benefit traditional banks. The inconsistency of results across the time periods of the crisis is telling as market participants struggled to discern what access to these programs meant.     

The optimal currency basket under vertical trade

This paper explores the theory of optimal currency basket in a small open economy general equilibrium model with sticky prices. In contrast to existing literature, we focus on an economy with vertical trade, where the currencies in the basket may play different roles in invoicing trade flow. In a simple two-currency basket, one currency is used to invoice imported intermediate goods and is called “import currency”, while the other currency is used to invoice exported finished goods and is called “export currency”. We find that the optimal weights of the import currency and the export currency depends critically on the structure of vertical trade. Moreover, if a country decides to choose a single-currency peg, the choice of pegging currency also depends on how other competing economies respond to external exchange rate fluctuations.     

Local market makers, liquidity and market quality

We examine the role of geographically proximate (local) market makers in providing liquidity and improving the quality of a dealer market. Firms with active participation of local dealers enjoy lower quoted and effective spreads, as well as more informative prices. The beneficial effects from local market makers are not confined to a few “top” local dealers and they cannot be attributed to their participation in the firm's IPO syndicate or industry specialization. Further, we find that days with aggressive bidding from local market makers relative to their non-local counterparts are associated with significant positive abnormal returns, consistent with local market makers possessing information advantages. In summary, our results suggest that the information advantages of local market makers may be a contributing factor to the reduction in the cost of trading.     

The interbank market after the financial turmoil: Squeezing liquidity in a “lemons market” or asking liquidity “on tap”

After August 2007 the plumbing system that supplied banks with wholesale funding, the interbank market, failed because toxic assets obstructed the pipes. Banks were forced to squeeze liquidity in a “lemons market” or to ask for liquidity “on tap” from central banks. This paper disentangles the two components of the 3-month Euribor–Eonia swap spread, credit and liquidity risk and then evaluates the decomposition. The main finding is that credit risk increased before the key events of the crisis, while liquidity risk was mainly responsible for the subsequent increases in the Euribor spread and then reacted to the systemic responses of the central banks, especially in October 2008. Moreover, the level of the spread between May 2009 and February 2010 was influenced mainly by credit risk, suggesting that European banks were still in a “lemons market” and relied on liquidity “on tap” even before sovereign debt crisis unfolded in Europe.     

Analyzing determinants of bond yield spreads with Bayesian Model Averaging

This paper analyzes determinants of country default risk in emerging markets, reflected by sovereign yield spreads. The results reported so far in the literature are heterogeneous with respect to significant explanatory variables. This could indicate a high degree of uncertainty about the “true” regression model. We use Bayesian Model Averaging as the model selection method in order to find the variables which are most likely to determine credit risk. We document that total debt, history of recent default, currency depreciation, and growth rate of foreign currency reserves as well as market sentiments are the key drivers of yield spreads.     

Crash risk of the euro in the sovereign debt crisis of 2009–2010

The economic-political instability of a country, which is tied to its credit risk, often leads to sharp depreciation and heightened volatility in its currency. This paper shows that not only the creditworthiness of the euro-area countries with weaker fiscal positions but also that of the member countries with more sound fiscal positions are important determinants of the deep out-of-the-money euro put option prices, which embedded information on the euro crash risk during the sovereign debt crisis of 2009–2010. We also find evidence of information flow from the sovereign credit default swap market to the currency option market during the crisis.     

In- and out-of-sample specification analysis of spot rate models: Further evidence for the period 1982–2008

We review and construct consistent in-sample specification and out-of-sample model selection tests on conditional distributions and predictive densities associated with continuous multifactor (possibly with jumps) and (non)linear discrete models of the short term interest rate. The results of our empirical analysis are used to carry out a “horse-race” comparing discrete and continuous models across multiple sample periods, forecast horizons, and evaluation intervals. Our evaluation involves comparing models during two distinct historical periods, as well as across our entire weekly sample of Eurodollar deposit rates from 1982 to 2008. Interestingly, when our entire sample of data is used to estimate competing models, the “best” performer in terms of distributional “fit” as well as predictive density accuracy, both in-sample and out-of-sample, is the three factor Chen (Chen, 1996) model examined by Andersen, Benzoni and Lund (2004). Just as interestingly, a logistic type discrete smooth transition autoregression (STAR) model is preferred to the “best” continuous model (i.e. the one factor Cox, Ingersoll, and Ross (CIR: 1985) model) when comparing predictive accuracy for the “Stable 1990s” period that we examine. Moreover, an analogous result holds for the “Post 1990s” period that we examine, where the STAR model is preferred to a two factor stochastic mean model. Thus, when the STAR model is parameterized using only data corresponding to a particular sub-sample, it outperforms the “best” continuous alternative during that period. However, when models are estimated using the entire dataset, the continuous CHEN model is preferred, regardless of the variety of model specification (selection) test that is carried out. Given that it is very difficult to ascertain the particular future regime that will ensue when constructing ex ante predictions, thus, the CHEN model is our overall “winning” model, regardless of sample period.     

Deposit insurance coverage,ownership, and banks' risk-taking in emerging markets

We ask how deposit insurance systems and ownership of banks affect the degree of market discipline on banks' risk-taking. Market discipline is determined by the extent of explicit deposit insurance, as well as by the credibility of non-insurance of groups of depositors and other creditors. Furthermore, market discipline depends on the ownership structure of banks and the responsiveness of bank managers to market incentives. An expected U-shaped relationship between explicit deposit insurance coverage and banks' risk-taking is influenced by country specific institutional factors, including bank ownership. We analyze specifically how government ownership, foreign ownership and shareholder rights affect the disciplinary effect of partial deposit insurance systems in a cross-section analysis of industrial and emerging market economies, as well as in emerging markets alone. The coverage that maximizes market discipline depends on country-specific characteristics of bank governance. This “risk-minimizing” deposit insurance coverage is compared to the actual coverage in a group of countries in emerging markets in Eastern Europe and Asia.     

Do cross-country differences in bank efficiency support a policy of “national champions”?

As banking consolidation proceeds and Europe moves toward a single market, cross-country differences in banking efficiency can affect the future competitive position of a country’s financial market, helping to determine which European money centers may expand or contract. Looking at large banks across 10 countries, we find they are roughly equally efficient after controlling for differences in business environment, banking costs, and bank productivity. As no country seems to have a strong efficiency advantage, it seems likely that state efforts to promote “national champions” through favorable mergers which expand scale and market share may determine the outcome.     

The effects of reform on China’s bank structure and performance

This paper investigates the relationship between market structure and performance in China’s banking system from 1985 to 2002, a period when this sector was subject to gradual but notable reform. Using panel data estimation techniques, both the market-power and efficient-structure hypotheses are tested. In addition, the model is extended to consider issues such as the impact of bank size/ownership and whether the big four banks enjoy a “quiet life”. On average, X-efficiency declined significantly and most banks were operating below scale efficient levels. Estimation of the structure–performance models lends some support to the relative market-power hypothesis in the early period. The reforms had little impact on the structure of China’s banking sector, though the “joint stock” banks became relatively more X-efficient. There was no evidence to support the quiet-life hypothesis, probably because strict interest rate controls prevented the state banks from earning monopoly profits. Thus the ongoing liberalisation of interest rates should be accompanied by reduced concentration. Overall, to improve competitive structure, new policies should be directed at encouraging market entry and increasing the market share of the most efficient banks.     

Regionality revisited: An examination of the direction of spread of currency crises

What determines the direction of spread of currency crises? We examine data on waves of currency crises in 1992, 1994, 1997, and 1998 to evaluate several hypotheses on the determinants of contagion. We simultaneously consider trade competition, financial links, and institutional similarity to the “ground zero” country as potential drivers of contagion. To overcome data limitations and account for model uncertainty, we utilize Bayesian methodologies hitherto unused in the empirical literature on contagion. In particular, we use the Bayesian averaging of binary models that allows us to take into account the uncertainty regarding the appropriate set of regressors.We find that institutional similarity to the ground zero country plays an important role in determining the direction of contagion in all the emerging market currency crises in our dataset. We thus provide persuasive evidence in favour of the “wake-up call” hypothesis for financial contagion. Trade and financial links may also play a role in determining the direction of contagion, but their importance varies amongst the crisis periods.     

A darker side to decentralized banks: Market power and credit rationing in SME lending

We use loan-level data to study how the organizational structure of banks impacts small business lending. We find that decentralized banks—where branch managers have greater autonomy over lending decisions—give larger loans to small firms and those with “soft information.” However, decentralized banks are also more responsive to their own competitive environment. They are more likely to expand credit when faced with competition but also cherry pick customers and restrict credit when they have market power. This “darker side” to decentralized banks in concentrated markets highlights that the level of local banking competition is key to determining which organizational structure provides better lending terms for small businesses.     

Deposit insurance and subsidized recapitalizations

The 2007–2009 financial crisis saw a vast expansion in deposit insurance guarantees around the world and yet our understanding of the design and consequences of deposit insurance schemes is in its infancy. We provide a new rationale for the provision of deposit insurance. In our model the banking sector exhibits both adverse selection and moral hazard, which implies that the social benefits of bank monitoring must for incentive reasons be shared between depositors and banks. Consequently, socially too few deposits are made in equilibrium. Deposit insurance – or, equivalently, bank recapitalization – corrects this market failure. We find that deposit insurance should be funded not by banks or depositors but out of general taxation. The optimal level of deposit insurance varies inversely with the quality of the banking system. Hence, when the soundness of the financial sector is uncertain, governments should consider supporting deposit insurance schemes and undertaking subsidized recapitalizations.
