We study the provision problem of an asymmetrically valued public project using a novel mechanism proposed by Van Essen and Walker (2017). Under this mechanism, each player simultaneously submits a price (either a contribution or a requested compensation) and a desired project quantity. In our context, two non-hosts interact with the project’s host...
The authors adapted a lab-in-the-field experiment emulating the dynamic extraction of a fishery to create a Web-based classroom experiment. The game includes a multi-player version analogous to an open-access problem and a single-player version analogous to the social planner problem. This game is helpful in introductory microeconomics courses to t...
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 ego-relevance when the team production depends on the team’s top- or bottom-performer. Ego-relevance is manipulated by calling the Raven IQ Test an “IQ Task” or a “Patter...
We document how the procedure of allocating barely identical tasks among team members affects productivity and the willingness to pay for repeating the job alone rather than in teams. We find a complementarity relation between the assignment procedure (by-choice, imposed by a third party with a higher hierarchy, or random) and the preferences about...
We use a three-period model adopting a recursive definition of consumption to explore the optimal delegation that a present self, aware that her near-future self is present-biased but better informed, will make to protect her far-future self against income shocks. The model captures the present self's trade-off between using commitment mechanisms,...
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-...
Smiling is a popular and powerful facial signal used to influence how we are judged and evaluated by others. The recent COVID pandemic made the use of facemasks common around the world. Since facemasks, when properly worn, cover the lower half of the face, a common concern with them is that they inhibit our ability to signal to others through facia...
We create a dual labor market in the laboratory with participants selecting where to perform a real effort task: one with higher piece-rate and taxed labor income, resembling a formal market; or another without tax contributions, resembling an informal one. Although the tax revenue is divided among all participants, regardless of their chosen marke...
We propose an experiment where participants receive one of two contracts involving a piece-rate payment for performing a real-effort task. The differences in piece-rate levels aim to capture earnings differentials between formal and informal markets to study how the reallocation rules of these contracts, capturing labor mobility, affect the workers...
We conduct a lab-in-the-field experiment in which 214 rural workers must choose between a cash or a voucher payment for completing a real-effort task. Participants face a twenty-percent chance of suffering a negative shock that will reduce their cash payment by roughly two-thirds. Opting for the voucher reduces the likelihood of the shock by one-ha...
We conducted an audit experiment to examine whether street vendors in Bogotá (Colombia) exert price discrimination based on buyers’ attributes, such as gender and nationality, and based on product characteristics, such as the increasing marginal valuation of items needed to complete a collection. We exploited the seasonal demand for album stickers...
We designed and conducted an experiment of common-pool resource management involving economic and political inequality. Participants are assigned to different types differing in their endowments-Poor, Middle and Rich-and play an appropriation dilemma, with and without a voting procedure to select a quota limiting maximum extraction. Political inequ...
To contribute to the construction of young professionals with an integral profile in which the competitive spirit is promoted through the resolution of a technological challenge applied to the Oil & Gas industry, under a scenario that demands a high degree of commitment and with the accompaniment of professionals with great experience in the indust...
We employ the data from a karaoke contest to analyze strategic voting. Participants face a trade-off when voting for the contestant they want to eliminate. Excluding worst-performers increases the size of the prize allocated to the winner, whereas excluding top-performers increases the chances to become the winner. We analyze the performance and vo...
Do people discriminate between co-ethnics and others in cooperative interactions? In an experiment in China, we find that participants in trust games send around 15% more to partners they know to be co-ethnics than to those whose ethnicity they do not know. Receivers’ behavior is determined by amounts received and not by perceived ethnicity. In lin...
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 jointly endowe...
We study how individuals' contribution to a team production task varies depending on whether the task is ego relevant or not. We design and conduct an experiment to test the effect of ego-relevance in two types of team tasks: when contributions are complementary and substitutable. Ego-relevance is manipulated by calling the Raven IQ Test an “IQ Tas...
The provision of projects generating net benefits for several communities except for the host community poses two problems: where to locate the unpleasant facility, and how large this facility should be. We propose a mechanism that combines some market-like properties with a modified second-price auction. We elicit prices per unit as a host and as...
We design a framed bargaining experiment to explore how farmers allocate inherited land. In the experiment, two players with heterogeneous productivity inherit a land plot yielding a risky production, and some tokens to bargain over a land allocation. We conduct this experiment in Colombia with 256 participants from rural municipalities and 120 und...
We study the provision of a public project that globally behaves as a public good but locally behaves as a private bad. This scenario imposes two problems: (i) finding a compensation that makes the project acceptable for the pre-determined host, and (ii) securing the budget to pay for the project and the required compensation. We use a market-like...

... The resource can be given a slow but economically meaningful regeneration rate. For example, it could be framed as a fishery, where the regeneration rate is a function of the existing stock, as in Cortés, Mantilla, and Prada (2023). As another example, it could be framed as an aquifer, where the regeneration rate is exogenous. ...
... However, this fundamental detailwhich informs about the true (altruistic vs. antisocial) nature of punishment (Herrmann et al., 2008;Brañas-Garza et al., 2014;Espín et al., 2015) is by design unknown (but see Shinada et al., 2004), in contrast to the PGP. One recent PGP experiment with ethnic minorities in China also found that ingroup free-riders are punished less, and less than outgroup free-riders, when there are outgroups in the group; yet, the game is not one-shot but repeated, thus other motives might be at play (Mantilla et al., 2021). ...
... Por esto se debe hacer una investigación, la cual arroje como resultado precios accesibles y que a la vez la empresa obtenga beneficios, la participación de los clientes en la determinación de precios es importante, ya que son los que consumirán el producto (Sánchez-González & Herrera, 2014). Los clientes ejercen discriminación de precios en función de los atributos de los compradores, como el género y la nacionalidad, y en función de las características del producto (Zamora et al., 2021). ...
