Pecking order as a dynamic leverage theory

Static tradeoff theories, which do not explicitly treat the impact of transaction costs, do not explain the policy of asymmetry between frequent small debt transactions and infrequent large equity transactions. Nor do these theories explain why the debt ratio is allowed to wander a considerable distance from its alleged static optimum, or how much of a distance should be tolerated. We offer a class of diffusion models that mimic this behaviour in a stochastic-dynamic framework and are designed to optimize a financing strategy using any static tradeoff theory as input. The models developed reveal the determinants of the size and frequency of equity transactions and the range of values over which leverage variations are tolerated in four generic scenarios. They also yield a new formulation of the cost of capital that recognizes stochastic transaction costs and a penalty for deviation from any static-optimal leverage. Our class of models augments the pecking order theory, provides a flexible quantitative framework for its implementation as a decision tool, and facilitates the formulation of additional hypotheses for its empirical validation. Symmetrically, our results show the importance of dynamic factors in designing and interpreting empirical tests of static tradeoff theories. The results presented have important implications for the role played by static tradeoff theories in a stochastic-dynamic framework. One such implication is that the static-optimal leverage has no direct effect on the firm's leverage policy in this setting. The target leverage for refinancing transactions is different from the static-optimal leverage, and the mean leverage is generally different from both. As a consequence, the latter cannot be used to estimate the former. Another implication is that even when the mean leverage equals the static optimum, mean reversion is not an optimal behaviour and therefore not a legitimate test for the existence of a static tradeoff in a dynamic context. Still another implication is that wide variations in leverage ratios cannot be interpreted as evidence of leverage indifference. It follows that the pecking order theory is consistent with static tradeoff theories and does not require the assumption of leverage indifference.     

Characterization of a class of moral-hazard, adverse selection games

Studying a principal-agent game in which the agent alone observes the state of the world and reports it, but the moral hazard is not reducible, shows that, if the principal uses all signals, then no solution exists, i.e. there is no contract that elicits truth-telling and motivates the agent to exert effort. When the principal does not use signals on the state of the world that seem irrelevant, a solution exists in which some of the ex post signals on outcome are not used, even though they obey the informativeness condition of Holmstrom (Bell Journal of Economics, 1979, 10, 74–91).     

Incentives for voluntary disclosure

Rule l0b-5 of the 1934 Securities and Exchange Act allows investors to sue firms for misrepresentation or omission. Since firms are principal–agent contracts between owners – contract designers – and privately informed managers, owners are the ultimate firms’ voluntary disclosure strategists. We analyze voluntary disclosure equilibrium in a game with two types of owners: expected liquidating dividends motivated (VMO) and expected price motivated (PMO). We find that Rule l0b-5: (i) does not deter misrepresentation and may suppress voluntary disclosure or, (ii) induces some firms to adopt a partial disclosure policy of disclosing only bad news or only good news.     

Management's reporting strategy and imperfection of the capital market

Since the decision on the reported outcome is delegated to the management of the firm, it is commonly held that when the capital market is imperfect the manager achieves consumption smoothing by smoothing the reports relative to the actual outcome. Modeling the firm as a principal-agent contract shows the contrary. When the capital market is imperfect the firm's reporting strategy is conservative, as the manager never reports more than the actual outcome because of fear of an unfavorable future outcome. When the capital market is perfect the firm either smooths the report-reports more than the actual outcome when the actual outcome is low and reports less than the actual outcome when the outcome is hig-or reports more than the actual outcome in order to take advantage of the sharing rule being an increasing function of the report.     

Hedging Strategies of Financial Intermediaries: Pricing Options with a Bid-Ask Spread

This paper uses a model similar to the Boyle-Vorst and Ritchken-Kuo arbitrage-free models for the valuation of options with transactions costs to determine the maximum price to be charged by the financial intermediary writing an option in a non-auction market. Earlier models are extended by recognizing that, in the presence of transactions costs, the price-taking intermediary devising a hedging portfolio faces a tradeoff: to choose a short trading interval with small hedging errors and high transactions costs, or a long trading interval with large hedging errors and low transactions costs. The model presented here also recognizes that when transactions costs induce less frequent portfolio adjustments, investors are faced with a multinomial distribution of asset returns rather than a binomial one. The price upper bound is determined by selecting the trading frequency that will equalize the marginal gain from decreasing hedging errors and the marginal cost of transactions.     

Demand for the truth in principal–agent relationships

Consider the following puzzle: If earnings management is harmful to shareholders, why don’t they design contracts that induce managers to reveal the truth? To answer this question, we model the shareholders–manager relationship as a principal–agent game in which the agent (the manager) alone observes the economic outcome. We show that the limited liability (LL) of the agent, defined as the agent’s feasible minimum payment, might explain the demand for earnings management by the principal. Specifically, when the LL level is high (low), a contract that induces earnings management may be less (more) costly than a truth-revealing contract. This finding offers a new explanation of the demand for earnings management.     

Share values, inflation, and escalating tax rates

The interaction of inflation with a progressive tax system has been known to cause tax rates, and thus tax liabilities, to escalate with nominal income. Often blamed for having undesirable effects on investment and wealth, this feature of modern tax systems has not received formal treatment in the literature. The present study examines the impact of this inflation-related phenomenon upon the value of corporate equity within the framework of partial equilibrium. It is shown that the combination of moderate inflation and a mildly progressive rate structure may have a substantial adverse effect on share values, an effect sharply increasing with the firm's real growth rate. These results provide a partial explanation for the apparent conflict between the Fisherian hypothesis and the commonly observed inverse relationship between the rate of inflation and the deflated value of stock price indices. To the extent that occasional adjustment of tax schedules does not prevent taxpayers from being pushed toward higher tax brackets, these results suggest a sizable potential benefit from full indexation of tax rates in an economy suffering from chronic inflation. They also confirm the belief that failure to do so is expecially harmful to economic growth.     

INTERNATIONAL TRANSFER OF PRICING INFORMATION BETWEEN DUALLY LISTED STOCKS

International multiple listing offers a unique opportunity to study the efficiency of information transmission across national markets. The knowledge gained from observing a stock of the same company priced in multiple markets differs from what may be gained from observing relations across markets of aggregate price indices. We investigate five companies based in Israel whose stocks are listed on both the Tel Aviv Stock Exchange and NASDAQ. Our empirical tests of causality in price changes use the side-by-side Box-Jenkins ARIMA models and the Sims VAR model. Overall, the results show that price causality in dually listed stocks is unidirectional from the domestic market to the foreign market.
