Beliefs as a Means of Self-Control? Evidence from a Dynamic Student Survey

Abstract:

We repeatedly elicit beliefs about the returns to study effort in a panel survey of students of a large university course. A behavioral model of quasi-hyperbolic discounting and malleable beliefs yields the prediction that the dynamics of return beliefs mirrors the importance of exerting self-control, such that return expectations first increase as the exam approaches, and then sharply drop post-exam. Exploiting variation in exam timing to control for common information shocks, we find this prediction confirmed: average subjective expectations of returns increase by about 20% over the period before the exam, and drop by about the same amount afterwards.

Testing

Abstract:

We investigate the achievement impact of alternative uses of student assessments. Our dataset covers over 2 million students in 59 countries observed over 6 waves in the international PISA test 2000-2015. Our empirical model exploits the country panel dimension to investigate assessment reforms over time, taking out country and year fixed effects. The expansion of standardized external comparisons, both school-based and student-based, is associated with improvements in student achievement. The effect of school-based comparison is stronger in low-performing countries. By contrast, solely internal testing without external comparison and internal teacher monitoring including inspectorates do not affect student achievement.

Can Education Compensate the Effect of Population Aging on Macroeconomic Performance?

Author:

Rainer Kotschy (LMU Munich)
Sunde Uwe (LMU Munich)

Abstract:

This paper investigates the consequences of population aging and of changes in the education composition of the population for macroeconomic performance. Estimation results from a theoretically founded empirical framework show that aging as well as the education composition of the population influence economic performance. The estimates and simulations based on population projections and different counterfactual scenarios show that population aging will have a substantial negative consequence for macroeconomic performance in many countries in the years to come. The results also suggest that education expansions tend to offset the negative effects, but that the extent to which they compensate the aging effects differs vastly across countries. The simulations illustrate the heterogeneity in the effects of population aging on economic performance across countries, depending on their current age and education composition. The estimates provide a method to quantify the increase in education that is required to offset the negative consequences of population aging. Counterfactual changes in labor force participation and productivity required to neutralize aging are found to be substantial.

Communicating Subjective Evaluations

Author:

Matthias Lang (LMU Munich)

Abstract:

Consider managers evaluating their employees' performances. Should managers justify their subjective evaluations? Suppose a manager's evaluation is private information. Justifying her evaluation is costly but limits the principal's scope for distorting her evaluation of the employee. I show that the manager justifies her evaluation if and only if the employee's performance was poor. The justification assures the employee that the manager has not distorted the evaluation downwards. For good performance, however, the manager pays a constant high wage without justification. The empirical literature demonstrates that subjective evaluations are lenient and discriminate poorly between good performance levels. This pattern was attributed to biased managers. I show that these effects occur in optimal contracts without any biased behavior.

Show What You Risk - Norms for Risk Taking

Author:

Stefan Grimm (LMU Munich)

Abstract:

Most economic decisions are embedded in a specific social context. In many such contexts, individual choices are influenced by their observability due to underlying social norms and social image concerns. This study investigates the impact of choices being observed, compared to anonymity of choices, on risk taking in a laboratory experiment. I relate participants' investments in a risky asset directly to social norms for risk taking that are elicited in an incentivized procedure. I find that risk taking is not affected by the choice being observed by a matched participant. Nor do investments follow elicited norms for risk taking more closely when observed. This holds when considering males and females separately. However, I provide strong evidence for gender-specific norms in risk taking. While these explain part of the existing gender gap in risk taking, males still "overshoot" by investing more than the norm dictates. This is particularly true for males being matched with a female participant.

Class Rank and Long-Run Outcomes

Abstract:

This paper considers a fundamental question about the school environment - what are the long run effects of a student's ordinal rank in elementary school? Using administrative data from all public school students in Texas, we show that students with a higher third grade academic rank, conditional on ability and classroom effects, have higher subsequent test scores, are more likely to take AP classes, graduate high school, enroll in college, and ultimately have higher earnings 19 years later. Given these findings, the paper concludes by exploring the tradeoff between higher quality schools and higher rank.

Can Online Surveys Represent the Entire Population?

Author:

Abstract:

A general concern with the representativeness of online surveys is that they exclude the "offline" population that does not use the internet. We run a large-scale opinion survey with (1) onliners in web mode, (2) offliners in face-to-face mode, and (3) onliners in face-to-face mode. We find marked response differences between onliners and offliners in the mixed-mode setting (1 vs. 2). Response differences between onliners and offliners in the same face-to-face mode (2 vs. 3) disappear when controlling for background characteristics, indicating mode effects rather than unobserved population differences. Differences in background characteristics of onliners in the two modes (1 vs. 3) indicate that mode effects partly reflect sampling differences. In our setting, re-weighting online-survey observations appears a pragmatic solution when aiming at representativeness for the entire population.

Who Teaches the Teachers? A RCT of Peer-to-Peer Observation and Feedback in 181 Schools

Author:

Felix Weinhardt (DIW Berlin)
Gillian Wyness (University College London)
Richard Murphy (University of Texas at Austin)

Abstract:

It is well established that teachers are the most important in-school factor in determining student outcomes. However, to date there is scant robust quantitative research demonstrating that teacher training programs can have lasting impacts on student test scores. To address this gap, we conduct and evaluate a teacher peer-to-peer observation and feedback program under Randomized Control Trial (RCT) conditions. Half of 181 volunteer primary schools in England were randomly selected to participate in the two year program. We find that students of treated teachers perform no better on national tests a year after the program ended. The absence of external observers and incentives in our program may explain the contrast of these results with the small body of work which shows a positive influence of teacher observation and feedback on pupil outcomes.

Seasonal Scarcity and Sharing Norms

Author:

Vojtech Bartos (LMU Munich)

Abstract:

How does scarcity affect individual willingness to share and willingness to enforce sharing from others? Sharing in poor communities gains importance as an insurance mechanism during adverse shocks, yet shocks make it costlier to share. I conducted repeated economic experiments in both a lean and a relatively plentiful post-harvest season with the same group of Afghan subsistence farmers experiencing annual seasonal scarcities. I separate altruistic motives from enforcement effects using dictator and third party punishment games. While altruistic sharing remains temporally stable, the enforcement of sharing weakens substantially in times of scarcity. Temporal norms fluctuations seem to drive the results.

How Lotteries in School Choice Help to Level the Playing Field

Author:

Abstract:

The use of lotteries is advocated to desegregate schools. We study lottery quotas embedded in the two most common school choice mechanisms, namely deferred and immediate acceptance mechanisms. Some seats are allocated based on merit (e.g., grades) and some based on lottery draws. We focus on the effect of the lottery quota on truth-telling, the utility of students, and the student composition at schools, using theory and experiments. We find that the lottery quota strengthens truth-telling in equilibrium when the deferred acceptance mechanism is used while it has no clear effect on truth-telling in equilibrium for the immediate acceptance mechanism. This finds support in the experiment. Moreover, the lottery quota leads to more diverse school populations in the experiments, as predicted. Comparing the two mechanisms, students with the lowest grades profit more from the introduction of the lottery under immediate than under deferred acceptance.
