Cognitive Ability, Character Skills, and Learning to Play Equilibrium: A Level-k Analysis

In this paper we investigate how cognitive ability and character skills influence 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. Finally, we compare the influence of cognitive ability to that of character skills, and find that both cognition and personality affect behavior and learning. More agreeable and emotionally stable subjects perform better and learn faster, although the effect of cognitive ability on behavior is stronger than that of character skills.

Gender Differences and Dynamics in Competition: The Role of Luck

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.

A Novel Computerized Real Effort Task Based on Sliders

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 (American Economic Review, 2012). 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.

Cognitive Ability and Learning to Play Equilibrium: A Level- k Analysis

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’

Longevity, life-cycle behavior and pension reform

How can public pension systems be reformed to ensure fiscal stability in the face of increasing life expectancy? To address this question, we use micro data to estimate a structural life-cycle model of individuals’ employment, retirement and consumption decisions. We calculate that, in the case of Germany, an increase of 3.76 years in the pension age thresholds or a cut of 26.8% in the per-year value of public pension benefits would offset the fiscal consequences of the increase in life expectancy anticipated to occur over the next 40 years. On average, individuals value the increase in the pension age thresholds at 3.44% of baseline consumption, and are willing to forgo 8.51% of baseline consumption to avoid the cut in per-year pension value. The increase in the pension age thresholds makes 87.7% of individuals better-off, and generates large responses in labor supply and retirement behavior. However, the favorable effects of this reform depend on the availability of jobs for older individuals.

Modeling Employment Dynamics with State Dependence and Unobserved Heterogeneity

This study extends existing work on the dynamics of labor force participation by distinguishing between full-time and part-time employment and by allowing unobserved heterogeneity in the effects of previous employment outcomes, children and education on labor supply behavior. In addition, unobserved heterogeneity may feature autocorrelation and correlated random effects. The results reveal significant variation in the effects of children and education on labor supply behavior. Moreover, the omission of random coefficients and autocorrelation biases estimates of state dependencies. On average, temporary shocks that increase the rate of part-time employment lead subsequently to lower rates of nonemployment than do shocks that temporarily increase the rate of full-time work.

Optimal Social Assistance and Unemployment Insurance in a Life-Cycle Model of Family Labor Supply and Savings

We analyze empirically the optimal mix and optimal generosity of social insurance and assistance programs. For this purpose, we specify a structural life-cycle model of the labor supply and savings decisions of singles and married couples. Partial insurance against wage and employment shocks is provided by social programs, savings, and the labor supplies of all adult household members. We show that the optimal policy mix focuses mainly on social assistance, which guarantees a permanent universal minimum household income, with a minor role for temporary earnings-related unemployment insurance. Optimal social assistance is moderately generous. Reflecting that married couples obtain intra-household insurance by making labor supply choices for both spouses, we also show that the optimal generosity of social assistance is decreasing in the proportion of married individuals in the population.

The Design of Unemployment Transfers: Evidence from a Dynamic Structural Life-Cycle Model

In this paper we use a dynamic structural life-cycle model to analyze the employment, fiscal and welfare effects induced by unemployment insurance. The model features a detailed specification of the tax and transfer system, including unemployment insurance benefits which depend on an individual’s employment and earnings history. The model also captures the endogenous accumulation of experience which impacts on future wages, job arrivals and job separations. For better identification of the structural parameters we exploit a quasinatural experiment, namely reductions over time in the entitlement period for unemployment insurance benefits which varied by age and experience. The results show that a policy cut in the generosity of unemployment insurance operationalized as a reduction in the entitlement period generates a larger increase in employment and yields a bigger fiscal saving than a cut operationalized as a reduction in the replacement ratio. Welfare analysis of revenue neutral tax and transfer reforms also favors a reduction in the entitlement period.

Employment effects of welfare reforms: Evidence from a dynamic structural life-cycle model

In this paper we develop a dynamic structural life-cycle model of labor supply behavior which fully accounts for the effects of income tax and transfers on labor supply incentives. Additionally, the model recognizes the demand side driven rationing risk that might prevent individuals from realizing their optimal labor supply state, resulting in involuntary unemployment. We use this framework to study the employment effects of transforming a traditional welfare state, as is currently in place in Germany, towards a more Anglo-American system in which a large proportion of transfers are paid to the working poor.

Using Goals to Motivate College Students: Theory and Evidence from Field Experiments

Will college students who set goals for themselves work harder and perform better? In theory, setting goals can help time-inconsistent students to mitigate their self-control problem. In practice, there is little credible evidence on the causal effects of goal setting for college students. We report the results of two field experiments that involved almost four thousand college students in total. One experiment asked treated students to set goals for performance in the course; the other asked treated students to set goals for a particular task (completing online practice exams). We find that performance-based goals had no discernible impact on course performance. In contrast, task-based goals had large and robust positive effects on the level of task completion, and task-based goals also increased course performance. Further empirical analysis indicates that the increase in task completion induced by setting task-based goals caused the increase in course performance. We also find that task-based goals were more effective for male students. We develop new theory that reinforces our empirical results by suggesting two key reasons why task-based goals might be more effective than performance-based goals: overconfidence and uncertainty about performance. Since task-based goal setting is low-cost, scaleable and logistically simple, we conclude that our findings have important implications for educational practice and future research.
