An Application of the English Clock Market Mechanism to Public Goods Games

This paper reports an experimental study of the public goods game in which contributions are not submitted all at once but incrementally as coordinated in real time by a clock. Individuals press a button as soon as the clock equals their willingness to contribute. By providing information about the point at which subjects stop further contributions we find evidence for conditionally cooperative behaviour: A subject's decision to stop contributing induces an immediate reaction of the other group members.     

Can second-order punishment deter perverse punishment?

Recent experiments have shown that voluntary punishment of free riders can increase contributions, mitigating the free-rider problem. But frequently punishers punish high contributors, creating “perverse” incentives which can undermine the benefits of voluntary punishment. In our experiment, allowing punishment of punishing behaviors reduces punishment of high contributors, but gives rise to efficiency-reducing second-order “perverse” punishment. On balance, efficiency and contributions are slightly but not significantly enhanced. JEL Classification C91 · C73 · C41 · D71     

The public and private provision of pure public goods and the distortionary effects of income taxation: a political economy approach

Abstract .  A pure public good is provided by the government and the voluntary contributions of two types of households. The government finances its contribution by means of income taxation. The latter has distortionary effects. A third type of household never makes contributions. We analyse the effects of changes in the income tax rate on (a) the provision of the public good, (b) the private contributions of the households, and (c) changes in the distribution of income and welfare between contributing and non-contributing households. We derive a simple and testable condition under which the lowering of the income tax entails a Pareto improvement.     

Information and IRA participation: the influence of tax preparers

The steep drop-off in the number of Individual Retirement Account (IRA) contributors after 1986 has led to suggestions that taxpayers misunderstood and over-reacted to the restrictions on deductible contributions imposed by the Tax Reform Act of 1986. Tax panel data is used to investigate the role of taxpayer misunderstanding in the drop-off in IRA contributors after 1986. The hiring of a tax preparer is the transmission mechanism for knowledge of the deductibility rules after 1986. The results suggest that more information and promotion of IRAs would have increased the probability of contributing to an IRA in 1987 for high income taxpayers, but would have decreased this probability for middle-income taxpayers. Taxpayer confusion over the deductibility restrictions appears to have been resolved by 1988. Therefore, taxpayer misunderstanding did not play a major role in the steep drop-off in the number of IRA contributors after 1986.     

Private Benefits,Warm Glow,and Reputation in the Free and Open Source Software Production Model

A great deal of production and consumption behavior takes place in the context of social organizations that seem to fall outside of the traditional paradigm of profit/utility maximization. These organizations are voluntary in nature and rely on contributions from members to achieve their objectives. Examples include the Linux operating system and other FOSS projects, political movements, churches and religious groups, Habitat for Humanity, and similar charitable organizations. In this paper, we consider a world containing agents with heterogeneous abilities who may voluntarily choose to make effort contributions to one or more different public projects. Agents are motivated by a desire to be seen as significant contributors to important and valuable projects, the warm glow from the act of contributing, and a desire to directly enjoy the benefits of projects when complete. We find that contributions from others can be either strategic complements or substitutes. We show that Nash equilibria exist and study how agents’ abilities and project quality affect the equilibrium levels of contributions.     

Foreign capital,credit constraints and continuity of firms’ R&D

In this article, we investigate the role of foreign capital participation as a means for firms to overcome the obstacle posed by credit constraints to sustain R&D investments. Using data for Spanish manufacturing firms in the period 1990–2006, we show that firms with foreign capital are significantly less likely to stop already initiated R&D projects and also more likely to sustain R&D investment when facing credit constraints. Our results are robust to positive selection into foreign capital participation, which we control through a set of variables chosen from a propensity score estimation, and to firms’ fixed-effects.     

Sequential teamwork in competitive environments: Theory and evidence from swimming data

Many tasks require the input by more than one person very often with members of the team contributing sequentially. However, team production is plagued by disincentive problems. We investigate individual incentives to team production with sequential contributions and competing teams. We show that earlier contributors free-ride on team members contributing later on. We test our predictions on sports data using an athlete's performance in the individual race as a natural control for his relay performance. Our empirical findings strongly support the theoretical claims.     

How strategy sensitive are contributions?

Summary. We test six hypotheses for contributions in dilemma games, a category that includes the prisoner's dilemma and public goods games. Our experiment focuses specifically on the strategic interdependence of contributing behavior, and manipulates the strategy space of a two-person dilemma game especially designed for the task. The hypothesis that contributors have non-linear preferences over own and the other player's payoffs accurately matches the strategic pattern of contributing that we observe across treatments. None of the reasons for contributing advanced by the other hypotheses, whether alone or in additive combination, does so.     

The Carrot vs. the Stick in Work Team Motivation

This paper reports on the use of carrot (positive) and stick (negative) incentives as methods of increasing effort among members of work teams. We study teams of four members in a laboratory environment in which giving effort towards the team goal is simulated by eliciting voluntary contributions towards the provision of a public good. We test the efficiency-improving properties of four distinct environments: monetary prizes given to high contributors versus monetary fines assessed to low contributors, where high/low contributor is defined first in terms of absolute contributions and then in terms of contributions relative to abilities—which we call handicapping. Our results show that both carrot and stick can increase efficiency (i.e., contributions) levels by 10–28%. We find that handicapped incentives promise the highest efficiency levels, and when handicapping is not used penalties may be more effective than prizes. The implications for work teams and suggestions for practical implementation are discussed.     

Substantive Rationality and Backward Induction

S. Modica and A. Rustichini (1994, Theory and Decision37, 107–124) provided a logic for reasoning about knowledge where agents may be unaware of certain propositions. However, their original approach had the unpleasant property that nontrivial unawareness was incompatible with partitional information structures. More recently, Modica and Rustichini (1999, Games Econ. Behav.27, 265–298) have provided an approach that allows for nontrivial unawareness in partitional information structures. Here it is shown that their approach can be viewed as a special case of a general approach to unawareness considered by R. Fagin and J. Y. Halpern (1988, Artificial Intelligence34, 39–76).

Giving is a Question of Time: Response Times and Contributions to an Environmental Public Good

Does it matter whether contribution decisions regarding environmental public goods are arrived at through intuition or reflection? Experimental research in behavioral economics has recently adopted dual-system theories of the mind from psychology in order to address this question. This research uses response time data in public good games to distinguish between the two distinct cognitive processes. We extend this literature towards environmental public goods by analyzing response time data from an online experiment in which over 3400 subjects from the general population faced a dichotomous choice between receiving a monetary payment or contributing to climate change mitigation efforts. Our evidence confirms a strong positive link between response times and contributions: The average response time of contributors is 40 % higher than that of non-contributors. This suggests that reflection, not intuition, is at the root of pro-environmental contributions. This result is robust to a comprehensive set of robustness checks, including a within-subjects analysis that controls for potentially unobserved confounds and recovers the relationship at the individual level.     

Dissertation abstract: A status theory of collective action

The “collective action problem” describes situations where each person in a group can individually profit more by withholding contributions to group goals. However, if all act in their material self-interest no public good is produced and all are worse off. I present a new solution to the collective action problem based on status. I argue that contributions to collective action increase an individual’s status in the group because contributions create perceptions of high group motivation, defined as the relative value an individual places on group versus individual welfare. Individuals are predicted to receive a variety of social and material benefits for their contributions to the group. These rewards can help explain why individuals contribute to collective action. Four laboratory studies tested the theory. In Study 1, following interaction in a 6-person public goods game, participants reported viewing higher contributors as more group motivated and higher status. Higher contributors also wielded more interpersonal influence in task interactions with participants. Participants also cooperated with higher contributors more, and allocated greater altruism to them in a Dictator game. Study 2 addressed an exchange-theoretic alternative explanation for the findings of Study 1, showing that observers of collective action who did not benefit from higher contributors’ contributions to the public good, nonetheless rated them as higher status, cooperated with them more, and gave them greater altruistic gifts. These results show that collective action contributors can earn social and material benefits even outside the group. Study 3 more directly tested the mediating role of group motivation. Contributors who sacrificed a greater proportion of resources for the collective action were rated as more group motivated and higher status than a moderate proportional contributor, even though the amounts they contributed were the same. These findings support the theory, and underscore the significance of self-sacrifice in the acquisition of status in collective action. Study 4 investigated the effects of status rewards on contributors’ behavior towards and perceptions of the group. Participants who received positive status feedback for their contributions subsequently contributed more than those who did not. Rewarded participants also identified more with the group and saw it as having greater solidarity and cohesion. I conclude by discussing theoretical implications and future research.

Doctoral Origins of Contributors to the American Economic Review, 1960-72

Professor Sun concludes that publishing performance, adjusted for differences in the number of Ph.D.'s granted, is not a function of the quality of graduate schools. Larger institutions appear to have an advantage by turning out a larger number of Ph.D.'s, but no correlation was found when the number of contributors to the AER from a school was compared with the rating of its graduate programs.

Economics departments may hope to improve their rating in doctoral programs by producing more Ph.D.'s and encouraging them to contribute to the AER, Professor Sun concludes.     

ESTIMATING THE INCIDENCES OF THE RECENT PENSION REFORM IN CHINA: EVIDENCE FROM 100,000 MANUFACTURERS

An ongoing reform in China mandates employers to contribute significant amounts to employee pension funds. The current study estimates the impact of this reform on the wage, employment, and performance of firms using data from over 140,000 medium and large manufacturers in China during 2004 and 2006. We find that the nominal wages of employees were rigid, but their real wages may have declined due to the pension reform. In addition, we find an interesting dichotomy in the incidences of pension reform. In localities with high agglomeration levels, firms' profits declined because the pension burden could not be fully transferred to employees. In less agglomerated jurisdictions, firms responded positively to pension reform, possibly because local governments over‐subsidized the pension costs as a way to attract investment.

Expectations, Drift, and Volatility in Evolutionary Games

This paper proposes an evolutionary model of learning in simple coordination games where expectations are the driving force of the process. As time proceeds, agents adjust their expectations through some (possibly different) updating rules, whose only requirement is that of consistency with long stationary evidence. Sporadically, expectations are also subject to arbitrary perturbation. The main point of the paper is that, due to the possibility of random drift on expectations, the evolutionary process will be subject to high volatility across equilibria. Specifically, every Nash equilibrium (even if risk- or payoff-dominated) will have significant positive weight in the long-run invariant distribution.

Asymmetric awareness and moral hazard

This paper introduces asymmetric awareness into the classical principal–agent model and discusses the optimal contract between a fully aware principal and an unaware agent. The principal enlarges the agentʼs awareness strategically when proposing a contract and faces a tradeoff between participation and incentives. Leaving the agent unaware allows the principal to exploit the agentʼs incomplete understanding of the world, relaxing the participation constraint, while making the agent aware enables the principal to use the revealed contingencies as signals about the agentʼs action choice, relaxing the incentive constraint. The optimal contract reveals contingencies that have low probability but are highly informative about the agentʼs effort.     

Rebate rules in threshold public good provision

This paper considers how six alternative rebate rules affect voluntary contributions in a threshold public-good experiment. The rules differ by (1) whether an individual can receive a proportional rebate of excess contributions, a winner-takes-all of any excess contributions, or a full rebate of one's contribution in the event the public good is provided and excess contributions exist, and (2) whether the probability of receiving a rebate is proportional to an individual's contribution relative to total contributions or is a simple uniform probability distribution set by the number of contributors. The paper adds to the existing experimental economics literature on threshold public goods by investigating both aggregate and individual demand revelation under the winner-take-all and random full-rebate rules. Half of the rules (proportional rebate, winner-take-all with uniform probability among all group members, and random full-rebate with uniform probability) provide total contributions that nearly equal total benefits, while the rest (winner-take-all with proportional probability, winner-take-all with uniform probability among contributors only, and random full-rebate with proportional probability) exceed benefits by over 30%. Only the proportional rebate rule is found to achieve both aggregate and individual demand revelation. Our experimental results have implications for both fundraisers and valuation practitioners.     

A UNIVERSAL FULLY FUNDED PENSION SCHEME

This paper puts forward a public pension scheme that is fully funded for each cohort and covers everybody. The scheme is an application of the generational accounting concept. As compared to pay-as-you-go schemes, it is free of the vagaries of uncertain demographic changes. Because payouts for each cohort are directly related to contributions, it is also free of political pressures to increase benefits. The paper looks at various refinements to the scheme and compares it with the Mandatory Private Provident Fund, which has become popular in recent years.     

NEGOTIATED SETTLEMENT UNDER MLB FINAL‐OFFER SALARY ARBITRATION SYSTEM

This paper provides a detailed analysis of negotiated salaries under Major League Baseball's final‐offer arbitration process using data from the 2007–2010 seasons. There is a wage premium of 25% for hitters and 14% for pitchers filing for arbitration. Interestingly, there is an additional premium for exchanging offers for hitters but not for pitchers. The additional premium in salary for hitters who exchange offers with their clubs amounts to 7%. (JEL J31, J52)
