Knowledge that Transforms

MATIF is the only major exchange offering a 24-hour non-interrupted trading cycle accommodating two distinct non-overlapping trading mechanisms. We find that trading volume on the floor is significantly higher than that on GLOBEX around the switch of trading mechanism. GLOBEX is mainly used by institutions to hedge their cash positions. The higher trading volume on the floor may be attributed to several factors: trade immediacy vs. transaction cost, liquidity trading by locals, inertia to trade under a new mechanism, and transparency vs. anonymity. In addition, the floor's open is unique with large interday return volatility.

This is the first study to examine the valuation effects of any antitakeover amendment on both bondholders and stockholders. We present new evidence documenting that, on average, there is a significant wealth loss experienced by bondholders at poison pill adoption announcement, while stockholders are unaffected. Our finding of significant bondholder losses is consistent with the proposed negative signal hypothesis. We document results which indicate that bondholders correctly anticipate the degree of leverage increase at the time of the announcement. We also show that the proportion of insider ownership is negatively related to bondholder wealth effect at announcement. This supports the notion that higher insider (manager) ownership leads to a greater alignment of manager-stockholder interests while increasing the stockholder-bondholder agency costs. Long-run analysis of leverage and performance measures reveal that pill adopting firms are not under-leveraged as compared to their industry rivals. However, supporting the negative signal hypothesis, the leverage of sample firms rises significantly after the pill adoption. Performance measures reveal that sample firms significantly underperform their industry cohorts. This result suggests that poison pill adoptions are motivated by poor managers attempting to immunize themselves from the disciplinary actions of the corporate control market.

In this paper, we test the synergy and internalization hypotheses for international acquisitions using a sample of foreign acquisitions of U.S. firms during the period 1979–1990. The major findings include: First, shareholders of our paired sample of U.S. targets and foreign acquirers experienced significantly positive combined wealth gains, $68 million on average, indicating that cross-border takeovers are generally synergy-creating activities. Second, shareholders of the U.S. targets realized significant wealth gains, regardless of the nationality of acquirers. Third, the Japanese acquisitions in our sample generated the largest net wealth gains, $398 million on average, which was shared by both target shareholders (43%) and acquirer shareholders (57%). Fourth, foreign acquirers benefitted from the targets' R&D capabilities, supporting the ‘reverse-internalization’ hypothesis.

This paper examines asset pricing theories for treasury bonds using longer maturities than previous studies and employing a simple multi-factor model. We allow bond factor loadings to vary over time according to term structure variables. The model examines not only the time variation in the expected returns of bonds but also their unexpected returns. This allows us to explicitly test some asset pricing restrictions which are difficult to study under existing frameworks. We confirm that the pure expectation theory of the term structure of interest rates is rejected by the data. Our empirical study of a two-factor model finds substantial evidence of time-varying term-premiums and factor loadings. The fact that factor loadings vary with long-term interest rates and yield spreads suggest that bond return volatilities are sensitive to interest rate levels.

This paper examines the impact of the risk-based capital (RBC) requirements on bank cost efficiencies. We take into consideration both on- and off-balance sheet (OBS) products and allow product mixes to differ across banks and to vary over time. Our empirical results suggest that the cost structures of large banks are significantly different during the pre-RBC and post-RBC periods. That is, the RBC change seemed to reduce the optimal bank size that achieves maximum scale and scope economies, so that some of the large banks that previously were efficient became too large and inefficient. The results suggest that regulations that encourage large banks to expand their production and product mixes any further will likely result in a less efficient banking industry.

This paper examines the impact on the liquidity of NYSE/AMEX listed stocks when they were subsequently listed on the London or the Tokyo Stock Exchanges. It can be argued that the increased competition from foreign market makers will reduce the monopoly rents that specialists can earn, thereby improving their quotes. We find, however, that spreads do not decrease following a dual listing, though the depth of the quotes increases as predicted. The apparent increase in depth disappears once we account for changes in price, volume and return variance. We also find that the level of informed trading increases, which increases the cost to the specialist of providing liquidity, and explains why spreads do not decline in spite of increased competition. Consistent with an increase in informed trading, we also document an increase in trading activity.

This paper presents an improved method of pricing vulnerable Black-Scholes options under assumptions which are appropriate in many business situations. An analytic pricing formula is derived which allows not only for correlation between the option's underlying asset and the credit risk of the counterparty, but also for the option writer to have other liabilities. Further, the proportion of nominal claims paid out in default is endogenous to the model and is based on the terminal value of the assets of the counterparty and the amount of other equally ranking claims. Numerical examples compare the results of this model with those of other pricing formulas based on alternative assumptions, and illustrate how the model can be calibrated using market data.

Unlike the Federal Savings and Loan Insurance Corporation and the Bank Insurance Fund, the National Credit Union Share Insurance Fund (NCUSIF) survived the 1980s without falling into a state of accounting insolvency. This paper analyzes how differences in incentive structure constrain the attractiveness of interest-rate speculation and other risk-taking opportunities to managers and regulators of credit unions. Despite these better incentives, robust present-value calculations establish that NCUSIF fell into economic insolvency during the mid-1980s. Besides calculating the extent of this insolvency, the paper also seeks to explain why, after NCUSIF became insolvent, it could rebuild its reserves without an explicit or implicit taxpayer bailout. Our explanation turns on cross-industry coinsurance responsibilities and the shallowness of the fund's observed insolvency relative to industry net worth. We identify forces in the decisionmaking environment tending to limit the depth and duration of unresolved insolvencies at individual credit unions. Managerial opportunities to benefit personally from taking risks that would flow through to NCUSIF are constrained by difficulties in converting a credit union to stockholder form and by the intensity of proactive monitoring of troubled credit unions by sister institutions and other private coinsurers. We conjecture that expanded use of coinsurance and private monitoring could reduce taxpayer loss exposure elsewhere in government deposit insurance systems.

In this paper alternative interest rate processes are estimated for Denmark, Germany, Sweden, and the UK, using the generalized method of moments (GMM). In line with the study by Chan, Karolyi, Longstaff, and Sanders (1992) on US data, there seems to be a positive relation between interest rate level and volatility for some countries. In contrast to their study, it is found that mean-reversion plays an important role for the specification of the interest rate dynamics. The results seem to be robust to the use of different moment conditions, and simulations of the estimated models reveal that they are fairly able to capture non-fitted moments as well. In addition, there is evidence of a structural change in the Danish interest rate process in August 1985, which may be due to a change in monetary policy. The small sample properties of the GMM estimators are also studied through simulations.

This paper examines the risk structure of bank holding companies and the effect of mutual fund activities on bank risk and profitability over the period 1987–1994. Findings from structural change tests indicate a significant decline in bank risk occurred near the mid-point of the study. Results from a confirmatory factor analytic model employed to examine the impact of mutual fund activities on banks suggest that mutual fund activities moderated bank industry systematic risk during the sample period. Mutual fund activities also increased the profitability of banks. These results suggest that mutual funds represent a productive avenue of expansion for bank holding companies.
