Gender Differences and Dynamics in Competition: The Role of Luck
(with
V. Prowse)
Oxford Department of Economics Discussion Paper 564.
PDF
Abstract
In a real effort experiment with repeated competition we find striking differences in how the work effort of men and women responds to previous wins and losses. For women losing per se is detrimental to productivity, but for men a loss impacts negatively on productivity only when the prize at stake is big enough. Responses to luck are more persistent and explain more of the variation in behavior for women, and account for about half of the gender performance gap in our experiment. Our findings shed new light on why women may be less inclined to pursue competition-intensive careers.

Competition in Posted Prices with Bargaining
(with
J. Thanassoulis)
Oxford Department of Economics Discussion Paper 639.
PDF
Abstract
In this paper we study price competition between firms when some consumers attempt to bargain while others buy at the public list or posted prices. Even though bargainers succeed in negotiating discounts off the list prices, their presence dampens competitive pressure in the market by reducing the incentive to undercut a rival's list price, thus raising all prices and increasing profits. Welfare falls because of the uncertainty in the bargaining process, which generates some misallocation of products to consumers. We also find that the bargainers facilitate collusion by reducing the market share that can be gained from a deviation. Hide

Cheating in the Workplace: An Experimental Study of the Impact of Bonuses and Productivity
(with
V. Prowse and
M. Vlassopoulos)
IZA Discussion Paper 6725.
PDF
Abstract
We use an online real-effort experiment to investigate how bonus-based pay
and worker productivity interact with workplace cheating. Firms often use
bonus-based compensation plans, such as group bonuses and firm-wide profit
sharing, that induce considerable uncertainty in how much workers are paid.
Exposing workers to a compensation scheme based on random bonuses makes them
cheat more but has no effect on their productivity. We also find that more
productive workers behave more dishonestly. We explain how these results
suggest that workers' cheating behavior responds to the perceived fairness of
their employer's compensation scheme.

Cognitive Ability and Learning to Play Equilibrium: A Level-k Analysis
(with
V. Prowse)
Oxford Department of Economics Discussion Paper 641.
PDF
Abstract
In this paper we investigate how cognitive ability influences behavior, success and the evolution of play towards Nash equilibrium in repeated strategic interactions. We study behavior in a p-beauty contest experiment and find striking differences according to cognitive ability: more cognitively able subjects choose numbers closer to equilibrium, converge more frequently to equilibrium play and earn more even as behavior approaches the equilibrium prediction. To understand better how subjects with different cognitive abilities learn differently, we estimate a structural model of learning based on level-k reasoning. We find a systematic positive relationship between cognitive ability and levels; furthermore, the average level of more cognitively able subjects responds positively to the cognitive ability of their opponents, while the average level of less cognitively able subjects does not respond at all. Our results suggest that, in strategic environments, higher cognitive ability translates into better analytic reasoning and a better 'theory of mind'.

Desert and Inequity Aversion in Teams
(with
R. Stone)
Oxford Department of Economics Discussion Paper 563.
PDF
Abstract
Teams are becoming increasingly important in work settings. We develop a
framework to study the strategic implications of a meritocratic notion of
desert under which team members care about receiving what they feel they
deserve. Team members find it painful to receive less than their perceived
entitlement, while receiving more may induce pleasure or pain depending on
whether preferences exhibit desert elation or desert guilt. Our notion of
desert generalizes distributional concern models to situations in which
effort choices affect the distribution perceived to be fair; in particular,
desert nests inequity aversion over money net of effort costs as a special
case. When identical teammates share team output equally, desert guilt
generates a continuum of symmetric equilibria. Equilibrium effort can lie
above or below the level in the absence of desert, so desert guilt generates
behavior consistent with both positive and negative reciprocity and may
underpin social norms of cooperation.

A Novel Computerized Real Effort Task Based on Sliders
(with
V. Prowse)
IZA Discussion Paper 5801.
PDF
Abstract
In this note, we present a novel computerized real effort task based on moving sliders
across a screen which overcomes many of the drawbacks of existing real effort tasks. The
task was first developed and used by us in Gill and Prowse (AER, forthcoming). We outline the design of
our "slider task", describe its advantages compared to existing real effort tasks and provide
a statistical analysis of the behavior of subjects undertaking the task. We believe that the
task will prove valuable to researchers in designing future real effort experiments, and to
this end we provide z-Tree code and guidance to assist researchers wishing to implement the
slider task. Hide
The Optimal Choice of Pre-Launch Reviewer
(with
D. Sgroi)
Journal of Economic Theory, 147(3), 1247-1260, 2012.
PDF
Abstract
We develop a framework in which: (i) a firm can have a new product tested publicly before launch; and (ii) tests vary in toughness, holding expertise fixed. Price flexibility boosts the strong positive impact on consumer beliefs of passing a tough test and mitigates the strong negative impact of failing a soft test. As a result, profits are convex in toughness: the firm selects either the toughest or softest test available. The toughest test is optimal when consumers start with an unfavorable prior and receive sufficiently uninformative private signals (an ``innovative" product); the softest test is optimal when signals are sufficiently informative.

A Structural Analysis of Disappointment Aversion in a Real Effort Competition
(with
V. Prowse)
American Economic Review, 102(1), 469-503, 2012.
PDF
Abstract
We develop a novel computerized real effort task, based on moving sliders across a screen, to test experimentally whether agents are disappointment averse when they compete in a real effort sequential-move tournament. Our theory predicts that a disappointment averse agent, who is loss averse around her endogenous expectations-based reference point, responds negatively to her rival's effort. We find significant evidence for this discouragement effect, and use the Method of Simulated Moments to estimate the strength of disappointment aversion on average and the heterogeneity in disappointment aversion across the population.

Fairness and Desert in Tournaments
(with
R. Stone)
Games and Economic Behavior, 69(2), 346-364, 2010.
PDF
Abstract
We model the behavior of agents who care about receiving what they feel they deserve in a two-player rank-order tournament. Perceived entitlements are sensitive to how hard an agent has worked relative to her rival, and agents are loss averse around their meritocratically determined endogenous reference points. In a fair tournament sufficiently large desert concerns drive identical agents to push their effort levels apart in order to end up closer to their reference points on average. In an unfair tournament, where one agent is advantaged, the equilibrium is symmetric in the absence of desert, but asymmetric in the presence of desert. We find that desert concerns can undermine the standard conclusion that competition for a fixed supply of status is socially wasteful and explain why, when the distribution of output noise is fat-tailed, an employer might use a rank-order incentive scheme.

The Impact of Bargaining on Markets with Price Takers: Too Many Bargainers Spoil the Broth
(with
J. Thanassoulis)
European Economic Review, 53(6), 658-674, 2009.
PDF
Abstract
In this paper we study how bargainers impact on markets in which firms set a list price
to sell to those consumers who take prices as given. The list price acts as an outside
option for the bargainers, so the higher the list price, the more the firms can extract
from bargainers. We find that an increase in the proportion of consumers seeking to
bargain can lower consumer surplus overall, even though new bargainers receive a
lower price. The reason is that the list price for those who do not bargain and the
bargained prices for those who were already bargaining rise: sellers have a greater
incentive to make the bargainers' outside option less attractive, reducing the incentive
to compete for price takers. Competition Authority exhortations to bargain can therefore
be misplaced. We also consider the implications for optimal seller bargaining. Hide
Sequential Decisions with Tests
(with
D. Sgroi)
Games and Economic Behavior, 63(2), 663-678, 2008.
PDF
Abstract
We consider a principal-agent problem where the principal wishes to be endorsed by
a sequence of agents, but cannot truthfully reveal type. In the standard "herding"
model, the agents learn from each other's decisions, which can lead to cascades on a
given decision when later agents' private information is swamped. We augment the
standard model to allow the principal to subject herself to a test designed to provide
public information about her type. She must decide how tough a test to attempt from
a continuum of test types, which involves trading off the higher probability of passing
an easier test against the greater impact from passing a tougher test. We find that the
principal will always choose to be tested, and will prefer a tough test to a neutral or easy
one. Hide
Strategic Disclosure of Intermediate Research Results
Journal of Economics and Management Strategy, 17(3), 733-758, 2008.
PDF
Abstract
We analyze the incentives to disclose intermediate research results during the
course of a patent contest. Despite knowledge spillovers, the leading innovator
sometimes discloses to signal commitment to the project, and so potentially
inducing a rival's exit. Surprisingly, when development costs are low the
leading innovator does not need to disclose to induce the same strategic
deterrence effect as that which arises from disclosure. Taking into account
wasteful duplication of R&D effort, a patent office can increase welfare by
choosing the probability of granting a contested patent and so altering the
proportion of rivals that the leading innovator deters. Hide
Soft Money and Hard Choices: Why Political Parties Might Legislate Against Soft Money Donations
(with
C.S. Lipsmeyer)
Public Choice, 123(3-4), 411-438, 2005.
PDF
Abstract
In contrast to the bulk of the campaign finance literature that highlights political action
committee (PAC) contributions and single donations, this paper emphasizes soft
money and the rationale for dual contributions. Employing a formal model of unregulated
contributions and political access, we show that donors will rationally choose to
contribute to both political parties. While the parties accept these dual contributions,
they lead to an imbalance between the benefits of contributions and the costs of providing
access. This race to acquire unlimited soft money leads to a situation where the
parties agree to campaign finance reform legislation. Hide

Abstract
With indivisible shareholdings and simultaneous shareholder decision-making, the existing takeover literature provides a reasonable profit only in asymmetric equilibria. We allow the raider to approach shareholders sequentially and thereby find a unique equilibrium that produces the same outcome. Hide
