Fund Managers' Contracts and Financial Markets' Short-Termism

This paper considers the problem faced by long-term investors who have to delegate the management of their money to professional fund managers. Investors can earn profits if fund managers collect long-term information. We investigate to what extent the delegation of fund management prevents long-term information acquisition, inducing short-termism. We also study the design of long-term fund managers' compensation contracts. Absent moral hazard, short-termism arises only because of the cost of information acquisition. Under moral hazard, fund managers' compensation endogenously depends on short-term price efficiency (because of the need to smooth fund managers' consumption), thereby on subsequent fund managers' information acquisition decisions. The latter are less likely to be present on the market if information has already been acquired initially, giving rise to a feedback effect. The consequences are twofold: First, this increases short-termism. Second, short-term compensation for fund managers depends in a non-monotonic way on long-term information precision. We derive predictions regarding fund managers' contracts and financial markets efficiency.

Equilibrium Discovery and Preopening Mechanisms in an Experimental Market

We experimentally analyze equilibrium discovery in i) a pure call auction, ii) a call auction preceded by a nonbinding preopening period, and iii) a call auction preceded by a binding preopening period. We examine whether a preopening period can facilitate coordination on the Pareto dominant equilibrium. During the nonbinding preopening period, traders tend to place manipulative orders. After observing such orders, participants learn to distrust cheap talk and coordinate less on Pareto dominant outcomes. In contrast, we find that, when preopening orders are binding, they improve the ability to coordinate on high gains from trade.

The Bubble Game: A classroom experiment

We propose a simple classroom experiment on speculative bubbles: the Bubble Game. This game is useful to discuss about market efficiency and trading strategies in a financial economics course, and about behavioral aspects in a game theory course, at all levels. The Bubble Game can be played with any number of students, as long as this number is strictly greater than one. Students sequentially trade an asset which is publicly known to have a fundamental value of zero. If there is no cap on asset prices, speculative bubbles can arise at the Nash equilibrium because no trader is ever sure to be last in the market sequence. Otherwise, the Nash equilibrium involves no trade. Bubbles usually occur with or without a cap on prices. Traders who are less likely to be last and have less steps of reasoning to perform to reach equilibrium are in general more likely to speculate

Rational and Irrational Bubbles: an Experiment

This paper proposes a theory of rational bubbles in an economy with finite trading opportunities. Bubbles arise because agents are never sure to be last in the market sequence. This theory is used to design an experimental setting in which bubbles can be made rational or irrational by varying one parameter. This complements the experimental literature on irrational bubbles initiated by Smith, Suchanek and Williams (1988). Our experimental results suggest that it is pretty difficult to coordinate on rational bubbles even in an environment where irrational bubbles flourish. Maximum likelihood estimations show that these results can be reconciled within the context of Camerer, Ho, and Chong (2004)'s cognitive hierarchy model, and Mc Kelvey and Palfrey (1995)'s quantal response equilibrium

Fund managers’ contracts and short-termism

This paper considers the problem faced by long-term investors who have to delegate the management of their money to professional fund managers. Investors can earn profits if fund managers collect long-term information. We investigate to what extent the delegation of fund management prevents long-term information acquisition, inducing short-termism in financial markets. We also study the design of long-term fund managers’ compensation contracts. Under moral hazard, fund managers’ compensation optimally depends on both short-term and longterm fund performance. Short-term performance is determined by price efficiency, and thus by subsequent fund managers’ information acquisition decisions. These managers are less likely to be active on the market if information has already been acquired initially, giving rise to a feedback effect. The consequences are twofold: First, short-termism emerges. Second, short-term compensation for fund managers depends in a non-monotonic way on long-term information precision. We derive predictions regarding fund managers’ contracts and financial markets efficiency

The "Washing Machine": Investment Strategies and Corporate Behavior with Socially Responsible Investors

This paper studies shareholder engagement in companies' strategic decisions. Differences of objective among shareholders arise in our model due to the presence of socially responsible investors. These investors take externalities into account when valuing their portfolio while conventional investors do not. Shareholders may affect corporate behavior via two mechanisms. They can vote with their feet: responsible investors may shy away from firms producing negative externalities, thereby raising their cost of capital. Investors can also engage in activism. Our main contribution is to show that a large activist investor can generate positive abnormal returns by investing in non-responsible companies and turning them into responsible. We call this strategy the \Washing Machine" and show that its successful implementation relies on a long-term horizon and a credible pro-social orientation
