A note on corporate taxation,limited liability,and asymmetric information

Becker and Fuest (this issue, p. 1–10) provides a new explanation for the link between limited liability and corporate taxation. The authors argue that a corporate tax on all entrepreneurs with limited liability is optimal when entrepreneurs can offset potential losses and when asymmetric information exists regarding projects’ qualities. This note considers a model with a slightly modified production technology. It confirms that entrepreneurs’ abilities to offset losses and the existence of asymmetric information may affect government policy. However, it also shows that the optimal taxation policy differs from that suggested by Becker and Fuest.      

Payout and asymmetric information

This article investigates the effects of payout policy on the level of asymmetric information in the market for common equity shares. The results suggest that higher dividend levels are associated with lower price impact, both as a percentage of economic value and as a percentage of the spread. And greater share repurchase ratios are associated with lower price impacts as a percentage of the spread. Overall, the results suggest that managers may have more than the choice of market settings as a means to improve the quality of the market for their stock and the efficiency of price.     

Adverse selection and bilateral asymmetric information

A simple principal-agent model with bilateral asymmetric information and common values is developed. The agent(s) has private information about his characteristics but does not knowhow these affect outcomes. The principal knows how the characteristics translate into outcomes, but does not observe the characteristics. It is shown that equilibrium contracts aresimple in being designednot to reveal the agent's characteristics. When the agent knows howsome of his characteristics affect the outcome, contracts will be differentiated with respect to precisely those characteristics. An application to the use of genetic information is considered.     

The president and asymmetric use of information

While presidents try to allocate resources to their interests in budgeting process, they have limited power to influence because the government budget is approved by the legislative body. This study investigates whether presidents asymmetrically use information on the efficiency of programs to allocate more resources to their interests. Specifically, I focus on leftover funds in the government reporting. Growing leftover funds indicate inefficiency of the programs as they are the results of lack of demand or operational problems in implementation. Using data from the Korean government, I find that the change of leftover funds of programs and the following year’s budget has a negative relation only when the change of leftover funds is negative, which suggests that the efficiency of the program improves. This phenomenon becomes more salient when the programs are related to the president’s political interests. This suggests that presidents allocate resources to the programs of their interests by asymmetrically using the information on efficiency. This study contributes to the extant literature by identifying one of the presidents’ tools to affect the budgeting process.     

Contracts and asymmetric information in the theory of the firm

This paper extends the Coase notation of firms as intermediaries between consumers and input owners to incorporate asymmetric information. We show that in some cases it is optimal for consumers to pay a fixed price for a product and to ignore how the firm operates and the profit that it makes. If firms have private information that consumers cannot cheaply obtain, however, we demonstrate that the optimal contract may require constraints on firms internal operations and profits. Our work provides conditions under which cost-plus contracts are optimal, and demonstrates when nonprofit firms are the preferred organization structure.     

Complete information pivotal-voter model with asymmetric group size and asymmetric benefits

We analyze a standard pivotal-voter model under majority rule, with two rival groups of players, each preferring one of two public policies and simultaneously deciding whether to cast a costly vote, as in Palfrey and Rosenthal (1983). We allow the benefit of the favorite public policy to differ across groups and impose an intuitive refinement, namely that voting probabilities are continuous in the cost of voting to pin down a unique equilibrium. The unique cost-continuous equilibrium depends on a key threshold that compares the sizes of the two groups.     

Core convergence with asymmetric information

We analyze the ex ante incentive compatible core for replicated private information economies. We show that any allocation in the core when the economy is replicated sufficiently often is approximately Walrasian for the associated Arrow–Debreu economy.     

Multi-player contests with asymmetric information

We consider imperfectly discriminating, common-value, all-pay auctions (or contests) in which some players know the value of the prize, others do not. We show that if the prize is always of positive value, then all players are active in equilibrium. If the prize is of value zero with positive probability, then there is some threshold number of informed players such that if there are less, all uninformed players are active, and otherwise all uninformed players are inactive.     

Universal banking,asymmetric information and the stock market

This paper aims to explore the role of the universal banking system in contributing to the stock market bust in the wake of the financial crisis 2008–2009 when bankers might have incentive to hide information from shareholders. We set up a stylized model of consumption smoothing involving universal banks that undertake both investment and commercial banking activities. Banks have private information about the outcome of a project that it funds. In the wake of bad news about the project, the banker has an incentive to sell lemon shares in a secondary market with the pretence of a liquidity crunch. Our model shows that such an incentive results in (i) a sharp discounting of stock prices, (ii) greater loan demand (iii) higher fraction of bank ownership of the borrowing firms, and (iv) heightened consumption risk resulting in precautionary savings by households. The magnitude of these effects depends on the market's perception about the preponderance of lemons in the stock market. A credible punishment scheme implemented by the government in the form of fines may moderate the stock market decline and consumption volatility due to information friction. However, it imposes a deadweight loss on private citizens because of a fall in all banks' expected profit. On the other hand, a “ring-fenced” banking arrangement along the way suggested by the Vickers Commission may entail a first order welfare loss due to the lack of diversification opportunities.     

Balancedness and the core in economies with asymmetric information

Summary. A condition is given that is equivalent to balancedness of all NTU-games derived from an exchange economy with asymmetric information when endowments are variable. The condition is applicable to the ex-ante model with expected utilities, but also to the more general model of Arrow-Radner type economies without subjective probabilities. Differences in the interpretation of measurability assumptions between these two models are discussed, and another model with information consistent utility functions is developed in which the result would also hold.

Stackelberg leadership under symmetric and asymmetric information

This Paper considers the types of pre-committments that a first moving incumbent may make when information is symmetric, and when it is asymmetric. The model contains as a special case the familiar model of Stackelberg leadership, but also shows the circumstances under which more complex strategies are optimal for the incumbent.     

Tariffs and the adoption of clean technology under asymmetric information

Abstract.  This paper examines the effect of a tariff on the decision of a foreign monopolist to adopt 'clean' technology, which reduces the flow of a negative cross-border externality. The clean technology increases the marginal cost of production relative to the dirty technology, but only the firm knows the extent of the increase. Under complete information, despite its protectionist motivation, the importing country's optimal tariff induces the firm to adopt the clean technology if and only if it is globally efficient to do so. Under incomplete information, this efficiency property is disrupted, and the firm biases its choice in favour of dirty technology. JEL classification: F13, F18     

Production and financial policies under asymmetric information

We propose an extension of the standard general equilibrium model with production and incomplete markets to situations in which (i) private investors have limited information on the returns of specific assets, (ii) managers of firms have limited information on the preferences of individual shareholders. The extension is obtained by the assumption that firms are not traded directly but grouped into ‘sectorial’ funds. In our model the financial policy of the firm is not irrelevant. We establish the existence of equilibria and discuss the nature of the inefficiencies introduced by the presence of asymmetric information. We also illustrate the properties of the model in three simple examples. We would like to thank Alberto Bisin, Armando Dominioni, Piero Gottardi, Tito Pietra, Paolo Siconolfi, and an anonymous referee for useful suggestions and comments.     

Market games with asymmetric information: the core

This paper concerns cores of economies with asymmetric information. Alternative definitions of the information available to traders in coalitions and the cooperative games they generate are analyzed. An important technical result states that such NTU games in characteristic function form are well defined. Properties of various cores with asymmetric information are examined. Sufficient conditions on information sharing rules are provided for the induced games to be totally balanced or balanced, so that their cores are nonempty. Incentive compatibility issues are considered. Finally, a perspective on this research area is provided.     

Competition in the stock market with asymmetric information

We build a game theoretical model to examine how the level of information advantage of insiders and the competition between insiders and sophisticated investors affect stock price movements and traders’ trading strategies and profits. We show that the competition between insiders and sophisticated investors can reduce the losses of less sophisticated investors, and thus alleviates the disadvantaged position of the less sophisticated investors. Further, traders’ profits are affected by the accuracy of insiders’ private information, and the number of days that insiders have obtained the information in advance. These findings show the importance of information transparency and the role of sophisticated investors in limiting insiders’ trading advantages and mitigating the expropriation of investors by insiders.     

信息不对称条件下的债务约束机制

债务水平表达了企业经营的信息,投资者利用这种信息可以评估企业的质量。在信息不对称条件下,债务首先成为红利的有效替代形式,具有减少企业自由现金流的作用,从而对管理者起到市场监督和提高资金使用效率的作用;其次,当企业出现债务违约时,就要进入破产程序,且由债权人决定是否清算或重组,为避免这种情况的发生,企业管理者将债务保持在最优水平;再者,债务期限结构的匹配模型,使得企业管理者将债务的期限结构保持在科学合理的状态,从而实现资本结构的优化。     

Learning about compliance under asymmetric information

Over time, inspection agencies gather information about firms’ pollution levels and this information may allow agencies to differentiate their monitoring strategies in the future. If a firm is less successful than its peers in reducing emissions, it faces the risk of being targeted for increased inspections in the next period. This risk of stricter monitoring might induce high-abatement cost firms to mimic low-abatement cost firms by choosing lower emission levels, while the latter might try to avoid being mimicked. We explain firms’ compliance decisions and the inspection agency's monitoring strategy by means of a signaling game which incorporates dynamic enforcement and learning. Interestingly, we show that the ongoing signaling game between firm types might lead to firms over-complying with the emission standard.     

On mixed markets with asymmetric information

In asymmetric information exchange economies involving both non-negligible and negligible agents, one should expect the failure of the private Core-Walras Equivalence Theorem. This paper shows that if “large” traders are similar to each other, then they lose their market power and hence the Equivalence Theorem can be restored. We also investigate on weaker equivalences among Walrasian expectations allocations, Aubin private core and private core allocations of the original mixed economy and the atomless one associated to it, without the assumption that all atoms are of the same type. Furthermore, extensions of Hervés-Moreno-Yannelis and Schmeidler Theorems (compare Hervés et al. in J Math Econ 41:844–856, 2005a; Schemidler in Econometrica 40:579–580, 1972) are given for differential information economies in which the feasibility constraints are imposed with an equality (exact feasibility).

上市公司会计信息披露民事责任的认定

目前我国上市公司生产和披露会计信息，主要遵循了程序理性原则。会计信息的低质量加上其他因素综合作用导致会计信息含量低下，会计信息对证券价格变动的解释功能微乎其撮，会计信息与投资者决策之间的相关性十分微小。因此，在认定上市公司因会计信息虚假陈述引发的民事责任时，应充分考虑会计信息生产和披露的特殊性及会计信息在证券市场中的作用极其有限这一现实，给予上市公司合理的免责事由。
