Testing for Team Spirit - An Experimental Study

It is often suggested that team spirit counteracts free-riding. Testing for team spirit with field data is difficult, however, due to an inherent identification problem. In this paper test for team spirit experimentally. In a team work task we vary subjects' information about relative team performance while we leave unchanged the structure of explicit incentives. We find that subjects contribute more to their team's project when teams observe each others' performance. We attribute this result to the enhancement of team spirit caused by asymmetric peer effects between observing teams.team spirit, peer effects, organization of work, public goods experiments

Trust on the Streets: A Natural Field Experiment on Newspaper Purchasing

A publisher uses an honor-system for selling a newspaper in the street. The customers make payments into a cash-box, but can also just take the paper without paying. Payments are not monitored and highly anonymous; hence customers exhibit trustworthiness if they pay for the paper. We run a natural field experiment to identify motives behind payments. The experiment reveals that trustworthiness is based on a social rather than a legal norm. Additional survey questions serve to identify individual-specific components of trustworthiness. We find effects of gender, age, family status, church attendance, measures of reciprocity, social connectedness, and social risk.trust; trustworthiness; natural field experiment; survey

Tax Salience, Voting, and Deliberation

Tax incentives can be more or less salient, i.e. noticeable or cognitively easy to process. Our hypothesis is that taxes on consumers are more salient to consumers than equivalent taxes on sellers because consumers underestimate the extent of tax shifting in the market. We show that tax salience biases consumers’ voting on tax regimes, and that experience is an effective de-biasing mechanism in the experimental laboratory. Pre-vote deliberation makes initially held opinions more extreme rather than correct and does not eliminate the bias in the typical committee. Yet, if voters can discuss their experience with the tax regimes they are less likely to be biased.Tax salience, learning, deliberation, voting

Pure Redistribution and the Provision of Public Goods

We study pure redistribution as a device to increase cooperation and efficiency in the provision of public goods. Experimental subjects play a two-stage game. The first stage is the standard linear public goods game. In the second stage, subjects can redistribute payoffs among other subjects in their group. We find that cooperation and efficiency increases substantially with this redistribution scheme, and that the redistribution option is popular. Our results provide an intuitive explanation for why an imposed redistribution rule, as proposed by Falkinger (1996), is capable of sustaining cooperation in the provision of public goods.experiment; public goods; redistribution

Testing the Mill hypothesis of fiscal illusion

According to the “Mill hypothesis”, the tax burden from indirect taxation is underestimated because indirect taxes are less “visible” than direct taxes. We experimentally test the Mill hypothesis and identify tax framing as a cause of fiscal illusion. We find that the tax burden associated with an indirect tax is underestimated, whereas this is not the case with an equivalent direct tax. In a referendum to tax and redistribute tax revenue, fiscal illusion is found to distort democratic decisions and to result in “excessive” redistribution. Yet, voters eventually learn to overcome fiscal illusion.fiscal illusion; voting behavior; indirect taxation; redistribution; learning

Honesty on the Streets: A Natural Field Experiment on Newspaper Purchasing

A publisher uses an honor system for selling a newspaper in the street. The customers are supposed to pay, but they can also pay less than the price or not pay at all. We conduct an experiment to study honesty in this market. The results show that appealing to honesty increases payments, whereas reminding the customers of the legal norm has no effect. Furthermore, appealing to honesty does not affect the behavior of the dishonest. These findings suggest that some people have internalized an honesty norm, whereas others have not, and that the willingness to pay to obey the norm differs among individuals. In a follow-up survey study we find that honesty is associated with family characteristics, self-esteem, social connectedness, trust in the legal system, and compliance with tax regulations.honesty, internalized social norm, natural field experiment, survey

Voting on Thresholds for Public Goods: Experimental Evidence

Introducing a threshold in the sense of a minimal project size transforms a public goods game with an inefficient equilibrium into a coordination game with a set of Pareto-superior equilibria. Thresholds may therefore improve efficiency in the voluntary provision of public goods. In our one-shot experiment, we find that coordination often fails and exogenously imposed thresholds are ineffective at best and often counter-productive. This holds under a range of threshold levels and refund rates. We test if thresholds perform better if they are endogenously chosen, i.e. if a threshold is approved in a referendum, because voting may facilitate coordination due to signaling and commitment effects. We find that voting does have signaling and commitment effects but they are not strong enough to significantly improve the efficiency of thresholds.provision of public goods; threshold; voting; experiments

Are We Taxing Ourselves? How Deliberation and Experience Shape Voting on Taxes

We let consumers vote on tax regimes in experimental markets. We test if taxes on sellers are more popular than taxes on consumers, i.e. on voters themselves, even if taxes on sellers are inefficiently high. Taxes on sellers are more popular if voters underestimate the extent of tax shifting in the market. We show that inexperienced voters are prone to such a tax-shifting bias, that experience is an effective de-biasing mechanism, but that pre-vote deliberation about tax regimes makes initially held opinions more extreme rather than correct. Our results suggest that voting on taxes is prone to bias and that easy-to-interpret facts are needed to de-bias voters.

Testing Enforcement Strategies in the Field: Legal Threat, Moral Appeal and Social Information

We run a large-scale natural field experiment to evaluate alternative strategies to enforce compliance with the law. The experiment varies the text of mailings sent to potential evaders of TV license fees. We find a strong alert effect of mailings, leading to a substantial increase in compliance. Among different mailing conditions a legal threat that stresses a high detection risk has a significant and highly robust deterrent effect. Neither appealing to morals nor imparting information about others’ behavior enhances compliance. However, the information condition has a positive effect in municipalities where evasion is believed to be common. Overall, the economic model of crime performs remarkably well in explaining our data.field experiments, law enforcement, compliance, deterrence
