Equilibrium Pricing and Optimal Hedging in Electricity Forward Markets

Spot power prices are volatile and since electricity cannot be economically stored, familiar arbitrage‐based methods are not applicable for pricing power derivative contracts. This paper presents an equilibrium model implying that the forward power price is a downward biased predictor of the future spot price if expected power demand is low and demand risk is moderate. However, the equilibrium forward premium increases when either expected demand or demand variance is high, because of positive skewness in the spot power price distribution. Preliminary empirical evidence indicates that the premium in forward power prices is greatest during the summer months.

Ownership Structure, Corporate Governance, and Firm Value: Evidence from the East Asian Financial Crisis

We use a sample of 800 firms in eight East Asian countries to study the effect of ownership structure on value during the region's financial crisis. The crisis negatively impacted firms' investment opportunities, raising the incentives of controlling shareholders to expropriate minority investors. Crisis period stock returns of firms in which managers have high levels of control rights, but have separated their control and cash flow ownership, are 10–20 percentage points lower than those of other firms. The evidence is consistent with the view that ownership structure plays an important role in determining whether insiders expropriate minority shareholders.

Book‐to‐Market Equity, Distress Risk, and Stock Returns

This paper examines the relationship between book‐to‐market equity, distress risk, and stock returns. Among firms with the highest distress risk as proxied by Ohlson's (1980) O‐score, the difference in returns between high and low book‐to market securities is more than twice as large as that in other firms. This large return differential cannot be explained by the three‐factor model or by differences in economic fundamentals. Consistent with mispricing arguments, firms with high distress risk exhibit the largest return reversals around earnings announcements, and the book‐to‐market effect is largest in small firms with low analyst coverage.

Multimarket Trading and Liquidity: Theory and Evidence

We develop a new model of multimarket trading to explain the differences in the foreign share of trading volume of internationally cross‐listed stocks. The model predicts that the trading volume of a cross‐listed stock is proportionally higher on the exchange in which the cross‐listed asset returns have greater correlation with returns of other assets traded on that market. We find robust empirical support for this prediction using stock return and volume data on 251 non‐U.S. stocks cross‐listed on major U.S. exchanges.

Back to the Beginning: Persistence and the Cross‐Section of Corporate Capital Structure

We find that the majority of variation in leverage ratios is driven by an unobserved time‐invariant effect that generates surprisingly stable capital structures: High (low) levered firms tend to remain as such for over two decades. This feature of leverage is largely unexplained by previously identified determinants, is robust to firm exit, and is present prior to the IPO, suggesting that variation in capital structures is primarily determined by factors that remain stable for long periods of time. We then show that these results have important implications for empirical analysis attempting to understand capital structure heterogeneity.

Does Corporate Diversification Destroy Value?

We analyze several hundred firms that expand via acquisition and/or increase their number of business segments. The combined market reaction to acquisition announcements is positive but acquiring firm excess values decline after the diversifying event. Much of the excess value reduction occurs because our sample firms acquire already discounted business units, and not because diversifying destroys value. This implies that the standard assumption that conglomerate divisions can be benchmarked to typical stand‐alone firms should be carefully reconsidered. We also show that excess value does not decline when firms increase their number of business segments because of pure reporting changes.

Debt, Leases, Taxes, and the Endogeneity of Corporate Tax Status

Published: 12/17/2002   |   DOI: 10.1111/0022-1082.55404

John R. Graham, Michael L. Lemmon, James S. Schallheim

We provide evidence that corporate tax status is endogenous to financing decisions, which induces a spurious relation between measures of financial policy and many commonly used tax proxies. Using a forward‐looking estimate of before‐financing corporate marginal tax rates, we document a negative relation between operating leases and tax rates, and a positive relation between debt levels and tax rates. This is the first unambiguous evidence supporting the hypothesis that low tax rate firms lease more, and have lower debt levels, than high tax rate firms.
