Healy and Palepu, J. Account. Econ. (2001), this issue, provide a broad review of the empirical disclosure literature. This discussion focuses on the empirical voluntary disclosure literature, and assumes firms’ disclosure policies are endogenously determined by the same forces that shape firms’ governance structures and management incentives. This provides not only a more focused view of the literature, but also alternative explanations for some of the results discussed in Review and specific suggestions for future research.

The purpose of this paper is two-fold. First, I attempt a taxonomy of the extant accounting literature on disclosure: that is, a categorization of the various models of disclosure in the literature into well-integrated topics. With regard to the taxonomy, I suggest three broad categories of disclosure research in accounting. The first category, which I dub “association-based disclosure”, is work that studies the effect of exogenous disclosure on the cumulative change or disruption in investors’ individual actions, primarily through the behavior of asset equilibrium prices and trading volume. The second category, which I dub “discretionary-based disclosure”, is work that examines how managers and/or firms exercise discretion with regard to the disclosure of information about which they may have knowledge. The third category, which I dub “efficiency-based disclosure”, is work that discusses which disclosure arrangements are preferred in the absence of prior knowledge of the information, that is, preferred unconditionally. Then, in the final section of the paper, I recommend information asymmetry reduction as one potential starting point for a comprehensive theory of disclosure. That is, I recommend information asymmetry reduction as a vehicle to integrate the efficiency of disclosure choice, the incentives to disclose, and the endogeneity of the capital market process as it involves the interactions among individual and diverse investors.

The first two main sections survey the roles of transnational networks in alleviating problems of contract enforcement and providing information about trading opportunities, respectively. The next section covers how domestic networks influence international trade through their impact on domestic market structure. Two overarching questions unify these sections: how do networks affect efficiency, and will networks grow or shrink in importance for international trade over time. The last main sections develop research agendas for two less studied areas: the role of intermediaries who can connect foreign agents to domestic networks and the ability of transnational production networks to facilitate technology transfer.

This paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates. A simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution. In the general non-linear income tax problem, this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of Mirrlees. The optimal non-linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution. These formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters.

Classroom education has public good aspects. The technology is such that when one student disrupts the class, learning is reduced for all other students. A disruption model of educational production is presented. It is shown that optimal class size is larger for better-behaved students, which helps explain why it is difficult to find class size effects in the data. Additionally, the role of discipline is analyzed and applied to differences in performance of Catholic and public schools. An empirical framework is discussed where the importance of sorting students, teacher quality, and other factors can be assessed.

This paper investigates the impact of asset liquidity on the valuation of corporate securities and the firm's financing decisions. I show that asset liquidity increases debt capacity only when bond covenants restrict the disposition of assets. By contrast, I demonstrate that, with unsecured debt, greater liquidity increases credit spreads on corporate debt and reduces optimal leverage. The model also determines the extent to which pledging assets increases firm value and relates the optimal size of the pledge to firm and industry characteristics. Finally, I show that asset liquidity and security provisions may help explain leverage ratios and credit spreads observed in practice.

We analyze the influence of firm and managerial characteristics on executive compensation. Consistent with theory, we find monitoring difficulties result in greater use of options while CEO and blockholder ownership result in less. Risky investment is positively related to options and negatively related to cash bonus and restricted stock, suggesting that firms use options to encourage managers to take risks. We find a negative (positive) relation between options and leverage (convertible debt) consistent with minimizing the agency costs of debt. Finally, we provide new evidence on managerial horizon and incentives, documenting a concave relation between cash bonus and CEO age.
