Low carbon martensitic stainless steel JFE410DB-ER with higher heat resistance and corrosion resistance than conventional steels for motorcycle brake disks has been developed. Effects of Nb and N on the heat resistant properties in 12%Cr-1.5%Mn steel were investigated for the purpose of enhancing heat resistance. Addition of Nb introduced fine Nb(C, N), and thereby prevented temper softening. Addition of N decreased the amount of coarse M 23 C 6 and increased the amounts of solute (C + N) and fine Cr 2 (C, N), and thereby prevented temper softening. Additions of Nb and N maintained proper hardness for rotor materials even after tempering at 550°C. Based on these findings, 12%Cr-1.5%Mn-0.13%Nb-0.05%C-0.04%N steel has been developed. The developed steel has excellent durability against temper softening at temperatures exceeding 500°C compared with conventional steels.

Over the period 1994–2003, 80% of targets and 37% of acquirers obtain a third-party assessment of the fairness of a merger or acquisition. These fairness opinions do not affect deal outcomes when used by targets, but they affect deal outcomes when used by acquirers. The deal premium is lower in transactions if the acquirer obtains a fairness opinion, and is further reduced if multiple advisors provide an opinion. However, the acquirer's announcement-period return is 2.3% lower if the acquirer has a fairness opinion, especially if the acquirer pays a high premium, indicating that investors are skeptical of these transactions.

Many classes of microstructure models, as well as intuition, suggest that it should be easier to trade when markets are more active. In the data, however, volume and liquidity seem unrelated over time. This paper offers an explanation for this fact based on a simple frictionless model in which liquidity reflects the average risk-bearing capacity of the economy and volume reflects the changing contribution of individuals to that average. Volume and liquidity are unrelated in the model, but volume is positively related to the variance of liquidity, or liquidity risk. Empirical evidence from the U.S. government bond and stock markets supports this new prediction.

This paper presents a new pattern in the cross-section of expected stock returns. Stocks tend to have relatively high (or low) returns every year in the same calendar month. We recognize the annual cross-sectional autocorrelation pattern documented in Jegadeesh [1990. Evidence of predictable behavior of security returns. Journal of Finance 45, 881–898] at lags of 12, 24, and 36 months as part of a general pattern that lasts up to 20 annual lags, superimposed on the general momentum/reversal patterns. This pattern explains an economically and statistically significant magnitude of the cross-sectional variation in average stock returns. Volume and volatility exhibit similar seasonal patterns but they do not explain the seasonality in returns. The pattern is independent of size, industry, earnings announcements, dividends, and fiscal year. The results are consistent with the existence of a persistent seasonal effect in stock returns.

This paper presents a new model for the valuation of European options, in which the volatility of returns consists of two components. One is a long-run component and can be modeled as fully persistent. The other is short-run and has a zero mean. Our model can be viewed as an affine version of Engle and Lee [1999. A permanent and transitory component model of stock return volatility. In: Engle, R., White, H. (Eds.), Cointegration, Causality, and Forecasting: A Festschrift in Honor of Clive W.J. Granger. Oxford University Press, New York, pp. 475–497], allowing for easy valuation of European options. The model substantially outperforms a benchmark single-component volatility model that is well established in the literature, and it fits options better than a model that combines conditional heteroskedasticity and Poisson–normal jumps. The component model's superior performance is partly due to its improved ability to model the smirk and the path of spot volatility, but its most distinctive feature is its ability to model the volatility term structure. This feature enables the component model to jointly model long-maturity and short-maturity options.

The appropriate measure of cash flow for valuing corporate assets is net payout, which is the sum of dividends, interest, and net repurchases of equity and debt. Variation in net payout yield, the ratio of net payout to asset value, is mostly driven by movements in expected cash flow growth, instead of movements in discount rates. Net payout yield is less persistent than dividend yield and implies much smaller variation in long-horizon discount rates. Therefore, movements in the value of corporate assets can be justified by changes in expected future cash flow.

This paper presents a model of a multinational firm's optimal debt policy that incorporates international taxation factors. The model yields the prediction that a multinational firm's indebtedness in a country depends on a weighted average of national tax rates and differences between national and foreign tax rates. These differences matter as multinationals have an incentive to shift debt to high-tax countries. The predictions of the model are tested using a novel firm-level dataset for European multinationals and their subsidiaries, combined with newly collected data on the international tax treatment of dividend and interest streams. Our empirical results show that a foreign subsidiary's capital structure reflects local corporate tax rates as well as tax rate differences vis-à-vis the parent firm and other foreign subsidiaries, although the overall economic effect of taxes on leverage appears to be small. Ignoring the international debt shifting arising from differences in national tax rates would understate the impact of national taxes on debt policies by about 25%.

In the three-year period following stock market liberalizations, the growth rate of the typical firm's capital stock exceeds its pre-liberalization mean by an average of 4.1 percentage points. Cross-sectional changes in investment are significantly correlated with the signals about fundamentals embedded in the stock price changes that occur upon liberalization. Panel-data estimations show that a 10-percentage point increase in a firm's expected future sales growth predicts a 2.9- to 3.5-percentage point increase in the growth rate of its capital stock. Country-specific changes in the cost of capital drive changes in investment but firm-specific changes in the cost of capital do not.

Although small firms are particularly sensitive to interest rates and other shocks, empirical work on corporate risk management has focused instead on large public companies. This paper studies fixed-rate and adjustable-rate loans to see how small firms manage their exposure to interest rate risk. Credit-constrained firms are found to match significantly more often with fixed-rate loans, consistent with prior research that shows the supply of credit shrinks during periods of rising interest rates. Banks originate a higher share of adjustable-rate loans than other lenders, ameliorating maturity mismatch and exposure to the lending channel of monetary policy. Time-series patterns in the fixed-rate share are consistent with recent evidence on debt market timing.
