Equilibrium with Default and Endogenous Collateral

We study a two‐period general equilibrium model with incomplete asset markets and default. We make collateral endogenous by allowing each seller of assets to fix the level of collateral. Sellers are required to provide collateral whose first‐period value, per unit of asset, exceeds the asset price by an arbitrarily small amount. Moreover, borrowers are also required to be fully covered by the purchase, in the first period, of state‐by‐state default insurance. These insurance contracts are offered by lenders. The insurance cost or revenue is a linear charge and plays the role of a spread penalizing borrowers who will incur in default and benefiting lenders who will suffer default. Under these assumptions, equilibrium always exists.     

Similarly traded securities: Greek common vs. preferred stock

This paper examines the price spread between voting (common) and non‐voting (preferred) stocks during the period 1990–95 for a sample of 55 Greek companies. Because in Greece preferred stocks are not essentially different from common stocks, a number of hypotheses were tested to explain the observed differences. The data reveal an average spread of 27.5% for the entire period which, however, varies across years considerably. In cross‐sectional regressions it was found that the volatility of common stock returns, the liquidity of common shares relative to preferred shares, the ownership concentration, and the minimum dividend yield guaranteed to preferred stockholders explain a significant portion of the spread.     

What Enhances Insider Trading Profitability?

This study analyses the factors triggering insider trading profitability. Since there is not much evidence on this topic in the continental-European context, we focus on the Spanish stock market. Our findings show that the main relevant factors (the timing ability of the insider, the transparency of the transaction and the level of free cash flow of the firm) are related to insiders’ opportunities behaviour, motivated by the lack of either managerial control within the firm or enforcement of insider trading regulation. The level of ownership concentration, the spread and the interaction between the size and the transparency of the transaction are other relevant factors, some of them tested for the first time in the insider trading literature.      

The leading indicator property of the term spread and the monetary policy factors in Japan

Many studies have observed the leading indicator property of the term spread (LIPTS), which indicates that the term spread—the difference between long- and short-term interest rates—has information on future economic conditions. We examine whether this property is related to monetary policy or not by using Japanese monthly data with consideration for structural changes. Results of structural change tests show that the term spread has predictive ability for the future economic activity from 1982:4 to 1997:8. Decomposing the term spread into three parts; one is explained by past monetary policy shocks, another is explained by expected future call rates and the other is the remaining part, we find that all three parts are significantly related to the future economic growth rate. Hence, we find that the monetary policy plays an important role for the LIPTS.     

On the importance of systematic risk factors in explaining the cross-section of corporate bond yield spreads

In this paper we examine the importance of systematic equity market factors in explaining the cross-sectional variation in yield spreads on corporate debt. Based on a sample of 1771 corporate bonds over the period from January 1985 to March 1998, we find that once the default-related variables are controlled for, bond betas or sensitivities to aggregate equity market risks have very limited explanatory power. This is in contrast to [Elton, E.J., Gruber, M.J., 2001. Explaining the rate spread on corporate bonds. Journal of Finance 56, 247–277] who find that market factors tied to expected returns are predominantly important, but who do not control for these variables (i.e. the relevant variables from structural models), possibly biasing their estimates. On the other hand, our finding that the systematic factors exhibit some limited explanatory power suggests that the standard contingent claims approach may not fully apply. This finding is consistent with previous research that bond betas are not completely irrelevant once market frictions are introduced. Overall, the evidence provides empirical support for the proposition that structural models capture important elements of corporate bond yield spread determination and equity market systematic factors are by no means predominant.     

VERTICAL DIFFERENTIATION AND THE DISTRIBUTION OF INCOME

The paper analyses the effects of income concentration on the behaviour of a duopoly with vertical product differentiation and uncovered market. By using a trapezoid distribution, we solve explicitly for market equilibrium as a function of a mean preserving spread of the income distribution. We show that overall more concentrated incomes imply stronger product differentiation, as the presence of a large share of middle‐income consumers stimulates a price competition, whose effects are dampened through an enlargement of the quality spread. While the high‐quality advantage and market coverage increase unambiguously in the degree of income concentration, the behaviour of prices is non‐monotone in the distribution parameter.     

Do reductions in tick sizes influence liquidity?

On 4 December 1995, the Australian Stock Exchange reduced the minimum tick size for stocks priced below $A0.50 and stocks priced above $A10. We use this natural experiment to examine the impact of tick size reductions on liquidity. The present paper reports that although lower tick sizes generally lead to increased liquidity, this result is not universal. Stocks with larger relative tick sizes experience the greatest improvement in liquidity, while stocks with small relative tick sizes and low trading volume experience reduced liquidity. There is no change in order exposure as a result of the reduced tick sizes.     

PRICING EQUITY DERIVATIVES SUBJECT TO BANKRUPTCY

We solve in closed form a parsimonious extension of the Black–Scholes–Merton model with bankruptcy where the hazard rate of bankruptcy is a negative power of the stock price. Combining a scale change and a measure change, the model dynamics is reduced to a linear stochastic differential equation whose solution is a diffusion process that plays a central role in the pricing of Asian options. The solution is in the form of a spectral expansion associated with the diffusion infinitesimal generator. The latter is closely related to the Schrödinger operator with Morse potential. Pricing formulas for both corporate bonds and stock options are obtained in closed form. Term credit spreads on corporate bonds and implied volatility skews of stock options are closely linked in this model, with parameters of the hazard rate specification controlling both the shape of the term structure of credit spreads and the slope of the implied volatility skew. Our analytical formulas are easy to implement and should prove useful to researchers and practitioners in corporate debt and equity derivatives markets.     

The Determinants of the Intermediary Spread: Evidence from Australian, UK and USA-based International Equity Funds

This paper develops and tests a new measure of mutual fund performance, based on Brennan's (1993a) equilibrium model of the pricing of retail financial products, which assumes that search costs of investors are non-trivial and cause the demand for mutual funds to be inelastic, thus creating an intermediary spread. This implies that the marginal costs of the intermediary spread in the form of expenses and sales load must be explicitly traded off against the marginal benefits in terms of the fund's return relative to a benchmark. The measure is used to evaluate the performance of twelve USA, eight UK and five Australian-based internationally diversified equity funds over the period 1982–95, and provides new insights into their performance in ways that are not revealed by the Jensen measure.
