Testing
Author:
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 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.

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.

Educational Inequality and Public Policy Preferences: Evidence from Representative Survey Experiments
Author:
Abstract:
To study how information about educational inequality affects public concerns and policy preferences, we devise survey experiments in representative samples of the German population. Providing information about the extent of educational inequality strongly increases concerns about educational inequality but only slightly affects support for equity-oriented education policies, which is generally high. The small treatment effects are not due to respondents' failure to connect policies with educational inequality or aversion against government interventions. Support for compulsory preschool is the one policy with a strong positive information treatment effect, which is increased further by informing about policy effectiveness.

Growing Up in Ethnic Enclaves: Language Proficiency and Educational Attainment of Immigrant Children
Author:
Abstract:
Does a high regional concentration of immigrants of the same ethnicity affect immigrant children's acquisition of host-country language skills and educational attainment? We exploit the exogenous placement of guest workers from five ethnicities across German regions during the 1960s and 1970s in a model with region and ethnicity fixed effects. Our results indicate that exposure to a higher own-ethnic concentration impairs immigrant children's host-country language proficiency and increases school dropout. A key mediating factor for this effect is parents' lower speaking proficiency in the host-country language, whereas inter-ethnic contacts with natives and economic conditions do not play a role.

Does Ignorance of Economic Returns and Costs Explain the Educational Aspiration Gap? Evidence from Representative Survey Experiments
Author:
Abstract:
The gap in university enrollment by parental education is large and persistent in many countries. In our representative survey, 74 percent of German university graduates, but only 36 percent of those without a university degree favor a university education for their children. The latter are more likely to underestimate returns and overestimate costs of university. Experimental provision of return and cost information significantly increases educational aspirations. However, it does not close the aspiration gap as university graduates respond even more strongly to the information treatment. Persistent effects in a follow-up survey indicate that participants indeed process and remember the information. Differences in economic preference parameters also cannot account for the educational aspiration gap. Our results cast doubt that ignorance of economic returns and costs explains educational inequality in Germany.

Skills, Signals, and Employability: An Experimental Investigation
Author:
Abstract:
As skills of labor-market entrants are usually not directly observed by employers, individuals acquire skill signals. To study which signals are valued by employers, we simultaneously and independently randomize a broad range of skill signals on pairs of resumes of fictitious applicants among which we ask a large representative sample of German human-resource managers to choose. We find that signals in all three studied domains - cognitive skills, social skills, and maturity - have a significant effect on being invited for a job interview. Consistent with the relevance, expectedness, and credibility of different signals, the specific signal that is effective in each domain differs between apprenticeship applicants and college graduates. While GPAs and social skills are significant for both genders, males are particularly rewarded for maturity and females for IT and language skills. Older HR managers value school grades less and other signals more, whereas HR managers in larger firms value college grades more.

Relative Consumption Preferences and Public Provision of Private Goods
Author:
Abstract:
This paper shows that the public provision of private goods may be justified on pure efficiency grounds in an environment where individuals have relative con- sumption concerns. By providing private goods, governments directly intervene in the consumption structure, and thereby have an instrument to correct for the ex- cessive consumption of positional goods. We identify sufficient conditions when the public provision of private goods is always Pareto-improving, even when (linear) consumption taxes are available. In fact, with the public provision of private goods, there are cases where first-best allocations can be achieved, and a luxury tax on the positional good is redundant.

Image Concerns and the Political Economy of Publicly Provided Private Goods
Author:
Abstract:
Governments often provide their citizens with goods and services that are also supplied in markets: education, housing, nutritional assistance, etc. We analyze the political economy of the public provision of private goods when individuals care about their social image. We show that image concerns motivate richer individuals to vote for the public provision of goods they themselves buy in markets, the reason being that a higher provision level attracts more individuals to the public system, enhancing the social exclusivity of market purchases. In effect, majority voting may lead to a public provision that only a minority of citizens use. Users in the public system may enjoy better provision than users in the private system. We characterize the coalitions that can prevail in a political equilibrium.

Self-Confidence and Unraveling in Matching Markets
Author:
Abstract:
We document experimentally how biased self-assessments affect the outcome of matching markets. In the experiments, we exogenously manipulate the self-confidence of participants regarding their relative performance by employing hard and easy real-effort tasks. We give participants the option to accept early offers when information about their performance has not been revealed, or to wait for the assortative matching based on their actual relative performance. Early offers are accepted more often when the task is hard than when it is easy. We show that the treatment effect works through a shift in beliefs, i.e., underconfident agents are more likely to accept early offers than overconfident agents. The experiment identifies a behavioral determinant of unraveling, namely biased self-assessments, which can lead to penalties for underconfident individuals as well as efficiency losses.
