Ego-relevance in team production
We study how individuals’ effort contribution to a team production task varies depending on whether the task is ego relevant or not. We conduct an experiment to test the effect of egorelevance when the team production depends on the team’s top- or bottom-performer. Egorelevance is manipulated by calling the Raven IQ Test an “IQ Task” […]
Discrimination in post-conflict settings: Experimental evidence from Colombia
After a civil war, community support for the reintegration of ex-combatants is crucial for peace-building. Using a crowdfunding campaign to promote trainees’ business ideas, we investigate whether university students discriminate against ex-combatants in Colombia. Our results show that there is no discrimination against ex-combatants in terms of donations compared with other trainees, but there is […]
Building inclusive institutions in polarized scenarios
We study how the polarization of voters and platforms influences political participation and the political inclusion of others in a series of lab-in-the-field experiments run in Colombia. We present a novel experimental methodology to understand the endogenous generation of political institutions in a polarized scenario. Participants in our experiment donate a substantial amount of money […]
Reintegration and forgiveness to ex-combatants in Colombia
The aftermath of over 50 years of uninterrupted conflict is not only underdevelopment and casualties. It is also the loss of social ties, the mistrust, and the difficulties to build a society where victims live with those who once were their perpetrators. These difficulties are many times linked to strong negative affect, prejudice, and skepticism […]
Citizens from 13 countries share similar preferences for COVID-19 vaccine allocation priorities
How does the public want a COVID-19 vaccine to be allocated?We conducted a conjoint experiment asking 15,536 adults in 13 countries to evaluate 248,576 profiles of potential vaccine recipients who varied randomly on five attributes. Our sample includes diverse countries from all continents. The results sug-gest that in addition to giving priority to health workers […]
How do risk attitudes affect pro-social behavior? Theory and experiment
We explore how risk preferences affect pro-social behavior under uncertainty. We analyze a modified dictator game in which the dictator can, by reducing her own sure payoff, increase the odds that an unknown recipient wins a lottery. We first augment a standard social preferences model with reference-dependent risk attitudes and then test the model’s predictions […]
Payment for ecosystem services and motivational crowding: Experimental insights regarding the integration of plural values via non-monetary incentives
Incentives based on extrinsic motivations such as Payments for ecosystem Services (PES) could negatively affect intrinsic motivations (i.e., motivational crowding-out). This effect may be evidenced when conservation levels, after PES intervention, decline relative to those existing before PES implementation. However, still few experimental studies have assessed PES effects on motivations once economic incentives are missing. […]
Preferences, uncertainty, and biases in land division: A bargaining experiment in the field
Divisions of rural land in developing countries reduce the possibilities of farmers to profit from agricultural returns to scale. We design and conduct a framed bargaining experiment to study whether land overvaluation (due to affective reasons) and uncertainty in land values are drivers for land division. In our bargaining game, two players with different agricultural […]
Costly norm enforcement through sanctions and rewards: An experiment with colombian future police officers
The increasing lack of trust in the police around the globe reduces their indirect benefits, related to citizens’ feelings of safety and beliefs that the police are “doing something” to fight crime. We explore whether this generalized lack of trust among citizens correlates with their beliefs’ accuracy regarding fairness norm enforcement in a lab-in-the-field experiment […]
Environmental valuation using bargaining games: an application to water
We characterize a general bargaining game useful for environmental valuation purposes. In this game, a jointly endowed asset is divisible into smaller units of two types:those with and without an associated costly attribute. Bargaining parties can use monetary transfers to their counterpart in exchange for accruing more units of the jointlyendowed asset. We show that […]
