Optimal Disclosure Policy in Oligopoly Markets

This paper examines the private and social optimality of full disclosure of private information in a two-period oligopoly model. An incumbent firm is privately informed about the market demand and its production cost after operating as a monopolist in the first period, and then competes against an entrant in the second period. Two main results are derived. First, it is shown that the incumbent is best off by pre-committing to disclose both the demand and cost information. By disclosing full information, the incumbent nullifies its self-defeating intertemporal incentives, which arise whenever it has private information about the market demand, its cost efficiency, or both. In addition, the equilibrium output variance is the largest under full disclosure, which benefits the incumbent ex ante. Second, the paper shows that the incumbent's full disclosure of the demand and cost information may or may not be desirable from a social efficiency standpoint. In particular, the correlation between the firms' production costs is crucial to the rank of disclosure policies in terms of their impact on social efficiency.     

Signalling and entry deterrence: a multidimensional analysis

I consider whether a privately informed incumbent can use limit pricing and upward distortions in advertising to deter profitable entry. Profitable entry is not deterred when the incumbent is privately informed only about its cost type. Profitable entry may be deterred, however, if the incumbent is privately informed about its cost type and its patience level. An equilibrium foundation is thus provided for the traditional hypothesis that limit pricing and aggressive advertising by an incumbent may deter profitable entry. At a methodological level, the article contributes by characterizing the refined equilibria of a signalling model with multiple dimensions of private information and multiple signals.     

Corporate risk management,product market competition,and disclosure

This paper studies the effects of hedge disclosure requirements on corporate risk management and product market competition. The analysis is based on a model of market entry and shows that to prevent entry incumbent firms engage in risk management when these activities remain unobserved by outsiders. In the resulting equilibrium, financial markets are well informed and entry is efficient. However, potential attempts for more transparency by additional disclosure requirements introduce a commitment device that provides incumbents with incentives to distort risk management activities thereby influencing entrant beliefs. In equilibrium, firms engage in significant risk-taking. This behavior limits entry and adversely affects the nature of competition in industries.     

Discretionary disclosure in the presence of dual distribution channels

A prevailing view in the disclosure literature is that firms who learn favorable market information are reluctant to disclose it, fearing it will attract new rivals. In this paper, we demonstrate that the presence of dual distribution arrangements, wherein consumers can purchase products either from traditional retail firms or directly from suppliers, can notably alter disclosure incentives. As under prevailing views, a retailer disclosing positive news risks entry by competitors. However, entry shifts the incumbent supplier–retailer relationship: the presence of new competitors leads the supplier to treat its retailer more as a strategic partner, translating into lower wholesale prices. This, in turn, can lead the retailer to willingly share favorable news, since such disclosure invites entry precisely when the retailer stands to benefit most from price concessions. Our results suggest that as dual distribution continues to increase in prominence, firms may be more willing to voluntarily disclose sensitive financial information particularly that which points to high demand for its products.     

A theory of risk disclosure

In this paper, we consider the price effects of risk disclosure. We develop a model in which investors are uncertain about the variance of a firm’s cash flows and the firm releases an imperfect signal regarding this variance. In our model, uncertainty over the riskiness of a firm’s cash flows leads to a variance uncertainty premium in its price. We demonstrate that risk disclosure decreases the firm’s cost of capital by reducing this premium and that the market response to risk disclosure is small when the expected level of risk is high. Moreover, we find that firms acquire and disclose more risk information when their cash flow risk is greater than expected. Finally, we demonstrate that in a multi-asset setting, only risk disclosure concerning systematic risks will impact the cost of capital.     

Public Disclosure of Forward Contracts and Revelation of Proprietary Information

Financial executives of firms engaged in forward contracting have raised concerns that mandated disclosure of those contracts would reveal proprietary information to rival firms. This paper considers the basis for those concerns in the framework of a duopoly in which one privately informed producer enters the forward market prior to production. In choosing its forward position, the firm considers the effects of that position on the forward price and second stage product market competition with its rival. Two regimes are considered: mandated disclosure and no disclosure. Under the former, the contracting firm faces a tension between exploiting its information advantage in the forward market and attempting to influence the production decision of its rival. On average, in equilibrium, the contracting firm gains a first-mover advantage, but at the cost of revealing its private information to its rival and extracting less expected gains from uninformed forward market participants. In contrast, with no disclosure, the contracting firm cannot influence rival firm beliefs, but extracts more expected gains from its private information in both the forward and product markets. On balance, the contracting firm prefers no disclosure. Moreover, parameterizations exist such that the rival also prefers that regime. These findings explain the opposition of respondents to draft proposals of Statement of Financial Standards No. 133.     

Information disclosure quality: correlation versus precision

We investigate how a multidimensional disclosure quality (i.e., correlation and precision) determines an optimal information disclosure strategy. We find that, for an infinitely lived, unlevered firm with market perfection, a truth‐telling disclosure is optimal at increasing the expected firm value. However, for a finitely lived, levered firm in the presence of market imperfections (e.g., bankruptcy cost), the optimal disclosure quality depends negatively on the level of imperfections. Once we consider the agency problem, such dependence can become positive, thereby highlighting the importance of a proper managerial‐incentive scheme to align the information disclosure interests of managers and shareholders.     

Entry,exit, and the determinants of market structure

This article estimates a dynamic, structural model of entry and exit for two US service industries: dentists and chiropractors. Entry costs faced by potential entrants, fixed costs faced by incumbent producers, and the toughness of short‐run price competition are important determinants of long‐run firm values, firm turnover, and market structure. In the dentist industry entry costs were subsidized in geographic markets designated as Health Professional Shortage Areas (HPSA) and the estimated mean entry cost is 11 percent lower in these markets. Using simulations, we find that entry cost subsidies are less expensive per additional firm than fixed cost subsidies.     

Does location matter for disclosure? Evidence from geographic segments

The segment disclosures of multinational companies provide strategic information. We use the location characteristics of geographic segments to identify the reasons for withholding or disclosing segments. We examine segment data from around the adoption of IFRS 8, a reporting standard that requires firms to reveal more disaggregated information. Consistent with a proprietary cost motive for nondisclosure, we find that segments in regions that are deemed better for business tend to be hidden, while higher entry barriers for a segment are positively related to disclosure. These effects appear to be stronger for firms for which proprietary cost motives are more important. Among the previously unrevealed segments, proprietary costs explain the nondisclosure of segment earnings and other relevant financial information for investors.     

Discretionary Disclosure: A Note

This article extends the models of discretionary disclosure. The level of disclosure will be affected by the costs of such disclosure. Verrecchia (1983) shows that when the cost of disclosure is fixed then the threshold level of disclosure is positively related to that cost. Verrecchia (1990a) shows that in the presence of fixed disclosure costs the threshold level of disclosure is negatively related to the quality of information (precision) to be disclosed. The intuition for the result is that as information is more precise, withholding it is more detrimental for the firm and hence the threshold for disclosure is lowered. The model here expands the cost of disclosure to be a function of information quality. When this is the case, the Verrecchia (1990a) unambiguous result does not hold. The presence of information quality in the cost function creates a countervailing force such that more precise information does not necessarily imply more disclosure. This creates the intuitive result that precise information of a proprietary nature might be withheld from the market.     

Segment Disclosure and Cost of Capital

We investigate whether segment disclosure influences cost of capital. Improved segment reporting is expected to decrease cost of capital by reducing estimation risk. However, in a competitive environment segment disclosure may also generate uncertainties about future prospects and lead to a larger cost of capital. Asset‐pricing tests confirm that segment disclosure is a priced risk factor. Also, segment disclosure reduces ex‐ante estimates of cost of equity capital and other measures connected to risk. These results suggest a negative relation between segment disclosure and cost of capital. Our results also show that competition reduces, but does not eliminate, the previous relationship.     

Competitive Costs of Disclosure by Biotech IPOs

This study empirically examines the impact of various competitive cost proxies on the extent of product‐related information disclosed by biotech initial public offerings (IPOs) in their prospectuses. The choice of biotech companies, which operate in a fiercely competitive environment, crystalizes the importance of competitive disclosure costs. The focus on product‐related information is aimed at a disclosure set for which potential competitive harm is a priori substantial. Our empirical analyses establish three disclosure determinants: the stage of product development, availability of patent protection, and venture capital backing. Additionally, we find the relative size of ownership retained by pre‐IPO owners to be negatively related to the extent of disclosure, as predicted by signaling models. We also document the expected inverse relation between the extent of information conveyed by the biotech IPOs and widely used measures of information asymmetry: the bid‐ask spread and quoted depth, as well as stock return volatility.     

The impact of replacement cost disclosure on security prices: New Evidence

A number of studies have tested for information content in the ASR 190 disclosure by comparing the conditional and unconditional distribution of abnormal security returns around the time of disclosure. Since no differences were observed, it was concluded that ASR 190 had no information content. The study reported below performs a similar test by estimating the regression function of the conditional distribution of abnormal returns. This test procedure controls for the information content in contemporaneous historical cost disclosure and uses a conditioning variable not considered in earlier tests. It finds statistically significant stock price effects. However, because most of the effects appear to precede the official announcement date by several months, it is unclear whether stock prices were responding to the leakage of the information content of ASR 190 prior to disclosure, to private production of information contained in ASR 190 or to a variable omitted from the study which happens to be correlated with replacement costs.     

Voluntary Disclosure with Informed Trading in the IPO Market

We examine voluntary disclosure and capital investment by an informed manager in an initial public offering (IPO) in the presence of informed and uninformed investors. We find that in equilibrium, disclosure is more forthcoming—and investment efficiency is lower—when a greater fraction of the investment community is already informed. Moreover, managers disclose more information when the likelihood of an information event is higher, more equity is issued, or the cost of information acquisition is lower. Investment efficiency and the expected level of underpricing are non‐monotonic in the likelihood that the manager is privately informed.     

Competition and voluntary disclosure: evidence from deregulation in the banking industry

We use the relaxation of interstate branching restrictions under the Interstate Banking and Branching Efficiency Act (IBBEA) to examine how increases in competition affect incumbents’ voluntary disclosure choices. States implemented the IBBEA over several years and to varying degrees, allowing us to identify the effect of increased competition on the voluntary disclosure decisions of both public and private banks. We find that increases in competition are associated with an increase in press releases. Overall, press releases become more negative in tone as entry barriers decrease. However, disclosures by public banks and by banks issuing equity become incrementally positive in tone when entry barriers decrease. Thus, the increase in disclosure is consistent with a dominant incentive to deter entry via negative information, which is mitigated by an incentive to communicate positive information to investors.     

上市公司分部信息披露动因与约束

分部信息的披露主体主要是上市公司.公司出于竞争投资者有限的资金等目的有自愿披露分部信息的动因.由于分部信息披露存在成本,在没有管制的情况下,企业出于自身利益最大化考虑,将通过对收益和成本的权衡来决定分部信息披露.由于分部信息披露的外部性、分部信息分布的不对称性等,不能完全依赖于自愿披露,必须对分部信息披露进行适度的管制,强制公司披露分部信息.     

Voluntary Disclosure of Bad News

Abstract:   This paper shows that in a voluntary disclosure environment entailing both a fixed disclosure cost and a variable proprietary cost, partial disclosure equilibria may arise in which firms voluntarily disclose bad private information to the public. Furthermore, it is shown that such equilibria may arise more frequently as the threat of incuring proprietary cost increases and/or the proprietary cost itself increases.

Investment Opportunity Set and Voluntary Disclosure of Prospective Information: A Simultaneous Equations Approach

Abstract:   This paper examines empirically the relationship between the level of disclosure of prospective information and the investment opportunity set for firms in New Zealand. Using a systems (two‐stage least squares) approach that explicitly controls for potential endogeneity between disclosure and IOS, we find that the level of prospective information disclosure is significantly and positively related to IOS in both specifications in our simultaneous analysis. Further, we document that prospective information disclosure is positively related to firm size and new security offerings, and is not related to inside ownership and firm profitability. IOS is positively impacted by a firm's investments in fixed assets and its profitability. Finally, we find that forward looking disclosure levels are positively related to the proportion of outside directors on the board and negatively related to barriers to entry, but these findings are not robust across alternative model specifications.     

On financial disclosure and the behavior of security prices

The paper addresses the question: what impact does a change of a firm's information-disclosure environment have on its stock price behavior? Assuming that disclosure does not have any effects on production financing programs, that the CAPM obtains, and information can be characterized as ‘linear’, a number of results are provided. It is shown that disclosure leads to increased variability in stock price; the result is consistent with several empirical studies [Beaver (1968), May (1971), and Patell and Wolfson (1979)]. Further, the price that would be expected in a richer information environment is simply equal to the price that actually obtains in a less rich environment. Finally, risk and return parameters are essentially independent of changes in the disclosure environment.
