CEO pay and the Lake Wobegon Effect

The “Lake Wobegon Effect,” which is widely cited as a potential cause for rising CEO pay, is said to occur because no firm wants to admit to having a CEO who is below average, and so no firm allows its CEO's pay package to lag market expectations. We develop a game-theoretic model of this Effect. In our model, a CEO's wage may serve as a signal of match surplus, and therefore affect the value of the firm. We compare equilibria of our model to a full-information case and derive conditions under which equilibrium wages are distorted upward.     

Competition in the Audit Market: Policy Implications

The audit market's unique combination of features—its role in capital market transparency, mandated demand, and concentrated supply—means it receives considerable attention from policy makers. We explore the effects of two market scenarios that have been the focus of policy discussions: mandatory audit firm rotation and further supply concentration due to the exit of a “Big 4” audit firm. To do so, we first estimate publicly traded firms' demand for auditing services, allowing the services provided by each of the Big 4 to be differentiated products. We then use those estimates to calculate how each scenario would affect client firms' consumer surplus. We estimate that, for U.S. publicly trade firms, mandatory audit firm rotation would induce consumer surplus losses of approximately $2.7 billion if rotation were required after 10 years and $4.7–5.0 billion if after only four years. We find similarly that exit by one of the Big 4 would reduce client firms' surplus by $1.4–1.8 billion. These estimates reflect only the value of firms' lost options to hire the exiting audit firm; they do not include likely fee increases resulting from less competition among audit firms. The latter could result in audit fee increases between $0.75–1.3 billion per year for mandatory rotation and $0.47–0.58 billion per year for the disappearance of a Big 4 audit firm. Such losses are substantial; by comparison, total audit fees for public firms were $11 billion in 2010.     

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.     

Risk Mutualization and Competition in Insurance Markets

The aim of this paper is to analyze the impact of mutual firms on competition in the insurance market. We distinguish two actors in this market: mutual firms, which belong to their pooled members, and traditional companies, which belong to their shareholders. Our approach differs from the literature by one crucial assumption: the expected utility of the consumers depends on the size of their insurance firm, which generates network externalities in this market. Thus, the choice of a contract results in a trade-off between the premium level and the probability of that premium being ex-post adjusted. The optimal contract offered by a mutual firm involves a systematic ex-post adjustment (negative or positive), while the contracts a company offers imply a fixed premium that is possibly negatively adjusted at the end of the contractual period. In an oligopoly game, we show that three types of configurations are possible at equilibrium: either one mutual firm or insurance company is active, or a mixed structure emerges in which two or more companies share the market with or without a mutual firm.     

Firm size,information acquisition and price efficiency

We present a model in a competitive market where traders choose between a small and a large firm to acquire costly private information, but they also obtain free public information by observing equilibrium share prices. Our major finding is the existence of a noisy rational expectation competitive equilibrium, in which there are more informed traders of the large firm than those of the small firm. As a result, share prices of the large firm are more informative than those of the small firm. Our empirical study supports the analytical results. By using a bivariate vector autoregressive regression, we are able to conduct a variance decomposition of share prices for different size portfolios. We find that prices of large-size portfolios are more informative because non-value-related price shocks are less important in driving price changes of large-size portfolios than in the case of small-size portfolios.     

Compensating Financial Experts

We propose a labor market model in which financial firms compete for a scarce supply of workers who can be employed as either bankers or traders. While hiring bankers helps create a surplus that can be split between a firm and its trading counterparties, hiring traders helps the firm appropriate a greater share of that surplus away from its counterparties. Firms bid defensively for workers bound to become traders, who then earn more than bankers. As counterparties employ more traders, the benefit of employing bankers decreases. The model sheds light on the historical evolution of compensation in finance.     

Consumer‐surplus‐enhancing collusion and trade

That collusion among sellers hurts buyers is a central tenet in economics. We provide an oligopoly model in which collusion can raise consumer surplus. A differentiated‐product duopoly operates in two geographically separated markets. Each market is home to a single firm, but can import, at a cost, from the foreign firm. Under some circumstances, a perfect cartel, relative to duopolistic competition, raises the price of the imported good and lowers the price of the home good. This raises welfare for most consumers and increases aggregate consumer surplus. A similar possibility result applies to autarky. Our analysis applies beyond the spatial setting.     

Avoiding market dominance: product compatibility in markets with network effects

As is well recognized, market dominance is a typical outcome in markets with network effects. A firm with a larger installed base offers a more attractive product which induces more consumers to buy its product which produces a yet bigger installed base advantage. Such a setting is investigated here but with the main difference that firms have the option of making their products compatible. When firms have similar installed bases, they make their products compatible in order to expand the market. Nevertheless, random forces could result in one firm having a bigger installed base, in which case the larger firm may make its product incompatible. We find that strategic pricing tends to prevent the installed base differential from expanding to the point that incompatibility occurs. This pricing dynamic is able to neutralize increasing returns and avoid the emergence of market dominance.     

Asymmetric Information and Risky Debt Maturity Choice

When capital market investors and firm insiders possess the same information about a company's prospects, its liabilities will be priced in a way that makes the firm indifferent to the composition of its financial liabilities (at least under certain, well-known circumstances). However, if firm insiders are systematically better informed than outside investors, they will choose to issue those types of securities that the market appears to overvalue most. Knowing this, rational investors will try to infer the insiders' information from the firm's financial structure. This paper evaluates the extent to which a firm's choice of risky debt maturity can signal insiders' information about firm quality. If financial market transactions are costless, a firm's financial structure cannot provide a valid signal. With positive transaction costs, however, high-quality firms can sometimes effectively signal their true quality to the market. The existence of a signalling equilibrium is shown to depend on the (exogenous) distribution of firms' quality and the magnitude of underwriting costs for corporate debt.     

Entry and pricing in a differentiated products industry: evidence from the ATM market

We estimate a structural equilibrium model of the automatic teller machine market (ATM) to evaluate the implications of regulating ATM surcharges. We use data on bank characteristics, potential and actual ATM locations, and consumer locations; identify the model parameters with a regression discontinuity design; and develop methods to estimate the model without computing equilibria. A surcharge ban reduces ATM entry 12% and consumer welfare 24% but increases firm profits 27%. Total welfare under either regime is 4% lower than the surplus maximizing level. The article can help shed light on the implications of unregulated entry for differentiated products industries.     

Oblivious equilibrium for concentrated industries

This article explores the application of oblivious equilibrium (OE) to highly concentrated markets. We define a natural extended notion of OE, called partially oblivious equilibrium (POE), that allows for there to be a set of strategically important firms (the “dominant” firms), whose firm states are always monitored by every other firm in the market. We perform computational experiments that explore the characteristics of POE, OE, and Markov perfect equilibrium (MPE), and find that POE generally performs well in highly concentrated markets. We also derive error bounds for evaluating the performance of POE for cases where MPE cannot be computed.     

IPO waves, product market competition, and the going public decision: Theory and evidence

We develop a new rationale for initial public offering (IPO) waves based on product market considerations. Two firms, with differing productivity levels, compete in an industry with a significant probability of a positive productivity shock. Going public, though costly, not only allows a firm to raise external capital cheaply, but also enables it to grab market share from its private competitors. We solve for the decision of each firm to go public versus remain private, and the optimal timing of going public. In equilibrium, even firms with sufficient internal capital to fund their new investment may go public, driven by the possibility of their product market competitors going public. IPO waves may arise in equilibrium even in industries which do not experience a productivity shock. Our model predicts that firms going public during an IPO wave will have lower productivity and post-IPO profitability but larger cash holdings than those going public off the wave; it makes similar predictions for firms going public later versus earlier in an IPO wave. We empirically test and find support for these predictions.     

Joint audit,audit market structure,and consumer surplus

We use a structural application of the discrete choice model to investigate how the introduction of a joint audit policy would affect audit market structure and consumer surplus. We perform this policy evaluation by identifying demand fundamentals in a joint audit regime and applying them to a single audit regime. We find that a joint audit requirement has the potential to change the audit market structure substantially but that the effects are sensitive to the specific policy design. For example, small audit firms gain market share in a joint audit regime but only if an equal sharing of the workload between the two joint auditors is not required. Our counterfactual analysis reveals that the introduction of a joint audit regime would be associated with a substantial loss of consumer surplus. The loss results from restricting clients from giving all of the audit work to their most preferred audit firm, but it is partly offset by gains in consumer surplus deriving from the opportunity to choose the best combination of auditor pairs.     

RISKY DEBT MATURITY CHOICE IN A SEQUENTIAL GAME EQUILIBRIUM

In this paper the choice of risky debt maturity structure is analyzed in a sequential game framework. The focus is on the set of viable equilibria when there are no transaction costs associated with the choice of debt maturity structure. It is shown that when changes in firm value are independent over time, both short- and long-term debt pooling are Nash sequential equilibrium outcomes. However, only the short-term debt pooling outcome satisfies the universal divinity refinement. Relaxing the assumption of independent changes in firm value, it is demonstrated that a separating equilibrium in which higher-quality firms issue short-term debt and low-quality firms issue long-term debt may exist. Furthermore, conditions exist under which long-term debt pooling is the universally divine outcome.     

Optimal CEO Compensation with Search: Theory and Empirical Evidence

We integrate an agency problem into search theory to study executive compensation in a market equilibrium. A CEO can choose to stay or quit and search after privately observing an idiosyncratic shock to the firm. The market equilibrium endogenizes CEOs’ and firms’ outside options and captures contracting externalities. We show that the optimal pay‐to‐performance ratio is less than one even when the CEO is risk neutral. Moreover, the equilibrium pay‐to‐performance sensitivity depends positively on a firm's idiosyncratic risk and negatively on the systematic risk. Our empirical tests using executive compensation data confirm these results.     

基于资产期限结构的流动性过剩的内涵、测度与因子分析

本文基于资产期限结构探讨了流动性过剩的内涵,并对流动性过剩进行了定量测度和因子分析,在此基础上,提出了流动性过剩的管理思路与策略。基于资产期限结构的流动性过剩可以分解为一期滞后流动性过剩、货币期限结构与均衡比例期限升水变化率三个因子,实证分析结果表明,三个因子的均衡值均呈现季度循环的特征。中央银行应明确流动性过剩的下限和上限,在同一年度内应采取流动性管理策略保持流动性稳定提高,在不同年度应保持高流动性过剩与低流动性过剩之间的转换。为实现流动性过剩季度循环的均衡路径并使其保持在上下限范围内,中央银行可以选择流动性管理工具依据季度循环的特征调控货币期限结构与均衡比例期限升水。     

Equilibrium model with default and dynamic insider information

We consider an equilibrium model à la Kyle–Back for a defaultable claim issued by a given firm. In such a market the insider observes continuously in time the value of the firm, which is unobservable by the market makers. Using the construction in Campi et al. (http://hal.archives-ouvertes.fr/hal-00534273/en/, 2011) of a dynamic three-dimensional Bessel bridge, we provide the equilibrium price and the insider’s optimal strategy. As in Campi and Çetin (Finance Stoch. 11:591–602, 2007), the information released by the insider while trading optimally makes the default time predictable in the market’s view at the equilibrium. We conclude the paper by comparing the insider’s expected profits in the static and dynamic private information case. We also compute explicitly the value of the insider’s information in the special cases of a defaultable stock and a bond.     

Information Content of Insider Trading Around Corporate Announcements: The Case of Capital Expenditures

There is gathering evidence of insider trading around corporate announcements of dividends, capital expenditures, equity issues and repurchases, and other capital structure changes. Although signaling models have been used to explain the price reaction of these announcements, a usual assumption made in these models is that insiders cannot trade to gain from such announcements. An innovative feature of this paper is to model trading by corporate insiders (subject to disclosure regulation) as one of the signals. Detailed testable predictions are described for the interaction of corporate announcements and concurrent insider trading. In particular, such interaction is shown to depend crucially on whether the firm is a growth firm, a mature firm, or a declining firm. Empirical proxies for firm technology are developed based on measures of growth and Tobin's q ratio. In the underlying “efficient” signaling equilibrium, investment announcements and net insider trading convey private information of insiders to the market at least cost. The paper also addresses issues of deriving intertemporal announcement effects from the equilibrium (cross-sectional) pricing functional. Other announcement effects relate the intensity of the market response to insider trading, variance of firm cash flows, risk aversion of the insiders, and characteristics of firm technology (growth, mature, or declining).     

Information Disclosure to Employees and Rational Expectations: A Game-Theoretical Perspective

This paper analyses the voluntary disclosure strategies of a privately informed firm manager when the information is relevant to both a financial market for valuation purposes and a union for wage bargaining purposes. Disclosure of favourable information may adversely affect the terms under which the firm can secure the required flow of labour and may thus lead to a decrease in the firm's market value. The paper shows that both a full-disclosure and a nondisclosure equilibrium may exist, which contradicts an earlier analysis of the issue made by Pope and Peel (1981).     

Voluntary Disclosures,Corporate Control,and Investment

We examine the valuation and capital allocation roles of voluntary disclosure when managers have private information regarding the firm’s investment opportunities, but an efficient market for corporate control influences their investment decisions. For managers with long‐term stakes in the firm, the equilibrium disclosure region is two‐tailed: only extreme good news and extreme bad news is disclosed in equilibrium. Moreover, the market’s stock price and investment responses to bad news disclosures are stronger than the responses to good news disclosures, which is consistent with the empirical evidence. We also find that myopic managers are more likely to withhold bad news in good economic times when markets can independently assess expected investment returns.
