Credit supply and corporate capital structure: Evidence from Japan

In this paper we examine how financial constraints, especially fluctuations in the supply of credit, affect the capital structure of 1537 publicly listed Japanese firms from 1980 to 2007, in a data set with 33,000 observations. It is one of the first studies to do so and is inspired by the recent studies of Leary (2009) and Faulkender and Petersen (2006). Japan was selected due to the extreme credit supply fluctuations observed during the last 30 years. It thus offers an ideal natural experiment to test the impact of credit supply on corporate capital structure. In particular, in our panel data study we investigated the impact of the asset bubble in the 1980s and the credit crunch of the late 1990s on corporate capital structure decisions. The results of this paper show, among other findings, that financial policy decisions are indeed influenced by monetary conditions and the supply of credit. In particular, smaller sized firms face financial constraints, especially during economic downturns.     

Explaining exchange rate volatility: an empirical analysis of ‘the holy trinity’ of monetary independence, fixed exchange rates, and capital mobility

This paper uses a panel of data from twenty-two countries between 1967 and 1992 to explain exchange rate volatility, focusing on potential tradeoffs between fixed exchange rates, independent monetary policy, and capital mobility. I use monetary models to parameterize monetary divergence and factor analysis to measure capital mobility. Exchange rate volatility is loosely linked to both monetary divergence and the degree of capital mobility. Interestingly, exchange rate volatility is significantly correlated with the width of the explicitly declared exchange rate band, even after taking monetary divergence and capital mobility into account.     

Microstructural dynamics in a foreign exchange electronic broking system

This paper explores the relationships between quotations, spreads and transactions in the Foreign Exchange market. Such interactions have been the subject of much work in markets such as the NYSE, but until now have gone unexamined in the FX market owing to a lack of data. Using a 7 hour, transactions-based data set we examine the determinants of both quote revisions and spreads. The results indicate that trades are a major factor in spread determination and quote revisions. Furthermore, there is evidence that the widely documented negative auto-correlation in quote returns is at least partially caused by the ‘thinness’ of this particular segment of the FX market.     

Inventories and optimal monetary policy in a small open economy

We study how inventory investment affects the design of optimal monetary policy in a New Keynesian small open economy model. We find that under producer currency pricing, when the intratemporal elasticity of substitution is smaller than 1, optimal monetary policy in our model with inventories is similar to a standard model without inventories. However, when the intratemporal elasticity of substitution is larger than 1, inventory investment increases the importance of nominal exchange rate stabilization relative to a standard model without inventories. The importance of nominal exchange rate stabilization increases with the intratemporal elasticity of substitution.     

Exchange rate dynamics under alternative optimal interest rate rules

We explore the role of interest rate policy in the exchange rate determination process. Specifically, we derive exchange rate equations from interest rate rules that are theoretically optimal under a few alternative settings. The exchange rate equation depends on its underlying interest rule and its performance could vary across evaluation criteria and sample periods. The exchange rate equation implied by the interest rate rule that allows for interest rate and inflation inertia under commitment offers some encouraging results — exchange rate changes “calibrated” from the equation have a positive and significant correlation with actual data, and offer good direction of change prediction. Our exercise also demonstrates the role of the foreign exchange risk premium in determining exchange rates and the difficulty of explaining exchange rate variability using only policy based fundamentals.     

Current account imbalances and financial integration in the euro area

While the current account of the euro area as a whole has remained almost balanced in the past two decades, several member countries have sizeable deficits or surpluses. In this paper, we interpret these imbalances as indicators of net capital flows among the euro-area countries. We distinguish between balances against the euro zone and the rest of the world and examine these for the EU-15 countries. We find that for euro members the net flows follow differences in per-capita incomes, even before the introduction of the euro. Our results show further that with the introduction of the common currency the elasticity with respect to per-capita incomes of net capital flows within the euro area has increased for the members of the euro zone. This increase can neither be observed for the flows between the euro members and the rest of the world nor for the flows between the countries that stayed outside the monetary union and the euro zone. We interpret this as evidence for increasing financial integration in the euro area. There is also some evidence suggesting that the introduction of the euro has led to some financial diversion.     

Securities class actions in the US banking sector: Between investor protection and bank stability

This paper investigates whether securities class actions (SCAs) can play a role in banking supervision, both as a warning signal of insolvency and as an instrument of market discipline to encourage bank managers to carefully evaluate risk. Two groups of US banks are compared over the 2000–2008 period. One includes banks that have faced at least one SCA, while the other is composed of non-targeted banks (control group). Results indicate that collective private litigation procedures are more frequently directed at financially fragile intermediaries exhibiting inadequate governance standards. Furthermore, banks which have been subjected to SCAs are likely to reduce their excessive risk positions. This supports the idea that SCAs could be efficiently employed as a complement to public supervisory activity in the banking sector.     

Monetary shocks, the exchange rate, and the trade balance

This paper investigates the response of the exchange rate and the trade balance to monetary policy innovations for the US economy during the period 1973:01–1993:12. The empirical findings indicate that contractionary monetary policy shocks lead to transitory appreciations of the real and the nominal exchange rate. Exchange rate appreciations that are caused by a temporary contractionary shock to monetary policy are correlated with a short-lived improvement in the trade balance which is then followed by a deterioration, giving support to the J-curve hypothesis.     

Joint effect of financial fragility and macroeconomic shocks on bank loan losses: Evidence from Europe

A reduced-form model including nonlinearities is estimated from pooled data from nine European countries during 1982–2004 to show the effects of macroeconomic shocks and financial fragility on bank loan losses. The main ingredients of the model are unanticipated-output and interest-rate shocks estimated from published macroeconomic and naïve forecasts. The model fits the data well, capturing the extremely high levels of loan losses witnessed in different financial crises.     

Calculating the equity cost of capital using the APT: the impact of the ERM

One of the expected benefits of membership of the Exchange Rate Mechanism (ERM) was a reduction in risk which should lead to a lower cost of capital and foster investment and growth. Using the APT, we investigate the behavior of the equity market risk premium for the London Stock Exchange prior to and during sterling's membership of the ERM. We find that prior to and during the first year of membership the equity market risk premium fell quite dramatically. However, when conflict between domestic and ERM policy requirements arose at the turn of 1991, the equity risk premium increased and continued to do so until sterling's exit, partially wiping out the benefits of membership of the ERM.     

Forward exchange market unbiasedness: the case of the Australian dollar since 1984

This paper implements a robust statistical approach to regression with non-stationary time series. The methods were recently developed in other work and are briefly exposited here. They allow us to perform regressions in levels with non-stationary time series data, they accommodate data distributions with heavy tails and they permit serial dependence and temporal heterogeneity of unknown form in the equation errors. With these features the methods are well suited to applications with frequently sampled exchange rate data, which generally display all of these empirical characteristics. Our application here is to daily data on spot and forward exchange rates between the Australian and US dollars over the period 1984–1991, following the deregulation of the Australian foreign exchange market. We find big differences between the robust and the non-robust regression outcomes and in the associated statistical tests of the hypothesis that the forward rate is an unbiased predictor of the future spot rate. The robust tests reject the unbiasedness hypothesis but still give the forward rate an important role as a predictor of the future spot rate.     

Analyst following of privatized firms around the world: The role of institutions and ownership structure

We examine which factors affect the decision of analysts to follow newly privatized firms as well as the factors that determine the extent of that following. Contrary to traditional private firms, privatized firms harbor particular uncertainties related to the government's commitment toward privatization. The first-stage estimation shows that the decision by analysts to initiate coverage of newly privatized firms is positively influenced by lower political risk, better judicial efficiency, better information disclosure, and effective extra-legal institutions in the country. Conditional on the decision to initiate coverage, the second-stage results indicate that the extent of analyst following is more important: (1) when there is control relinquishment by the government, (2) when there is more participation by foreign investors and employees, and (3) for those larger firms in nonstrategic sectors. Finally, analysts' coverage is negatively related to postprivatization ownership concentration and underpricing. This latter result runs counter to the existing evidence on private firms—that is, that underpricing “buys” coverage.     

Burgernomics: the economics of the Big Mac standard

In the course of PPP research, much of the debate over the validity has been over the choice of an appropriate ‘basket’ for making purchasing power comparisons. The different compositions of goods and services in these baskets across countries have resulted in arguments against their usefulness for PPP purposes. This problem is augmented by the existence of productivity differentials in traded and non-traded goods across countries. Therefore we consider the use of the Big Mac as the international monetary standard as being a more palatable alternative: It is produced locally in over 80 countries around the world, with only minor changes in recipe and thus has the flavour of ‘the perfect universal commodity’. Our results indicate that the Big Mac Index is surprisingly accurate in tracking exchange rates over the long-term, which is consistent with previous PPP research findings. We subsequently enhance our PPP comparisons by taking into account the productivity differentials between countries and excluding non-traded goods from the Big Mac Index to derive the No-Frills Index.     

Capital market imperfections and the theory of optimum currency areas

This paper studies how within- and cross-country capital market imperfections affect the welfare effects of forming a currency union. The analysis considers a bank-only world where intermediaries compete in Cournot fashion and monitoring and state verification are costly. The first part determines the credit market equilibrium and the optimal number of banks, prior to joining the union. The second part discusses the benefits from joining a currency union. A competition effect is identified and related to the added monitoring costs that banks may incur when operating outside their home country, through an argument akin to the Brander-Krugman “reciprocal dumping” model of bilateral trade. However, in our framework, whether joining a union raises welfare of the home country is ambiguous; it depends on the relative strength of “investment creation” and “intermediation diversion” effects.     

Is the dollar peg suitable for the largest economies of the Gulf Cooperation Council?

The slumping of the GCC currencies against other major currencies and the ensuing rising imported inflation have sparked an ongoing debate about the viability of the dollar peg. This paper extends and applies the contribution of Berger et al. (2001) to the largest economies of the GCC, namely Saudi Arabia, Qatar, and the UAE, by introducing a foreign inflation dimension. Empirical estimations suggest little or no evidence supporting the suitability of a fixed exchange rate regime in any of the three analyzed economies. It is this paper's contention that policy makers ought to play an immediate and active role in identifying a suitable more flexible exchange rate regime as well as an achievable timeline and road map to effectively abandoning the dollar peg.     

Disclosure and cost of equity capital in emerging markets: The Brazilian case

In this paper, we conjecture that the weak association between disclosure and cost of equity capital found in the literature (Botosan, 1997) can be caused by the high-level corporate disclosure environment found in the United States. We hypothesize that in low-level corporate disclosure environments the variability in disclosure practices across firms will be larger than in the United States, and, consequently, the marginal effect of voluntary disclosure policies will be higher. Using a newly developed Brazilian Corporate Disclosure Index (BCDI), our results confirm this hypothesis. Disclosure is strongly associated with ex ante cost of equity capital for Brazilian firms. The results are more pronounced for firms with less analyst coverage and low ownership concentration, as expected.     

Do Japanese banks lead or follow international business? An empirical investigation

Although many precedent studies analyze the factors that promote the internationalization of banks, we have no empirical evidence answering the question as to whether banks follow or lead the manufacturing industries. In this paper, we investigate empirically whether Japanese banks are leaders or followers of the manufacturing industries in the process of internationalization. Using the Granger causality test based on Hsiao's (Hsiao, 1979, 1981) sequential test procedures, we find that Japanese banks have led Japanese manufacturing industries in the process of internationalization in Asia and Oceania and that banks have followed the manufacturing industries in the Near East. Furthermore, there is no clear causality in North America and Europe. The banks' leadership in Asia and Oceania seems to demonstrate that Japanese banks have comparative advantage against host-country competitors in these regions, while Japanese banks seem to enter US or European financial centers in order to avoid domestic regulations.     

Estimating the credibility of an exchange rate target zone

Recent breakthroughs in the theory of exchange rate target zones have not been followed by similar contributions on the empirical side. The drift adjustment method of evaluating the credibility of a target zone has become common practice. However, the estimates of the expected rate of depreciation inside the band do not model knowledge of the band in the agents' information set. In this paper, a rational expectations limited-dependent variable method to estimate the expected rate of depreciation is used to remedy this weakness. In the case of the franc-mark target zone with daily data covering a 4-year period, we show that expected rates of devaluation of the order of 2.5% were still present in the early 1990s. Their reappearance in the autumn of 1992 may thus not be surprising.     

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.
