Formal enforcement punishing defectors can sustain cooperation by changing incentives. In this paper, we introduce a second effect of enforcement: it can also affect the capacity to learn about the group's cooperativeness. Indeed, in contexts with strong enforcement, it is difficult to tell apart those who cooperate because of the threat of fines from those who are intrinsically cooperative types. Whenever a group is intrinsically cooperative, enforcement will thus have a negative dynamic effect on cooperation because it slows down learning about prevalent values in the group that would occur under a weaker enforcement. We provide theoretical and experimental evidence in support of this mechanism. Using a lab experiment with independent interactions and random rematching, we observe that, in early interactions, having faced an environment with fines in the past decreases current cooperation. We further show that this results from the interaction between enforcement and learning: the effect of having met cooperative partners has a stronger effect on current cooperation when this happened in an environment with no enforcement. Replacing one signal of deviation without fine by a signal of cooperation without fine in a player's history increases current cooperation by 10%; while replacing it by a signal of cooperation with fine increases current cooperation by only 5%.

Most large real-world organizations contain multiple smaller groups, such as working groups within firms. However, can this sort of nested groups be used to alleviate coordination failures in the larger group? We report on a multi-player Stag Hunt experiment wherein we hierarchically structure a large group into mutually exclusive small groups. We offer varying incentive payments if efficient coordination is achieved at a large or small group level. The novelty of our design is that we hold the total payment size constant between treatments. In our nested incentive treatment, we reduce the reward for achieving large-group coordination by a small amount and reallocate the same amount to successful small-group coordination. The results reveal that incentive reallocations privileging small groups facilitate efficient large-group coordination in the nested group structure.

When affirmative action policies target more than one disadvantaged group, they contain uncertainty as to whether an individual who belongs to one of these groups was actually favored. In a laboratory experiment, we study how this feature affects outcomes of affirmative action in the form of quotas, and compare it with two other conditions, namely affirmative action with a certain favored group and no affirmative action. We find that when a group is favored with certainty and the social identity that triggers affirmative action is made salient, affirmed individuals are wrongly perceived as less competent, both by themselves and by others. Consequently, their willingness to compete does not increase and they are selected less for teamwork post competition. Affirmative action with uncertain favored groups does not distort belief in competence, and thus does not induce such unintended consequences. In contrast, it increases competition entry of the affirmed groups and enhances their chances of being selected for teamwork.

Do people discriminate between men and women when they have the option to punish defectors or reward cooperators? Here, we report on four pre-registered experiments that shed some light on this question. Study 1 (N = 544) shows that people do not discriminate between genders when they have the option to punish (reward) defectors (cooperators) in a one-shot prisoner’s dilemma with third-party punishment/reward. Study 2 (N = 253) extends Study 1 to a different method of punishing/rewarding: participants are asked to rate the behaviour of a defector/cooperator on a scale of 1–5 stars. In this case too, we find that people do not discriminate between genders. Study 3a (N = 331) and Study 3b (N = 310) conceptually replicate Study 2 with a slightly different gender manipulation. These latter studies show that, in situations where they do not have specific beliefs about the gender of the defector/cooperator’s partner, neither men nor women discriminate between genders.

We explore the efficiency and revenue of proportional auctions (PA) compared to first price auction (FPA) for budget-constrained bidders. PA auctions have been used in privatization of Russian assets and in cryptocurrency sales, as they can achieve higher efficiency and revenue than FPAs when bidders face severe financial constraints. The experimental results support this in that under a tight budget constraint PA achieved higher revenue and efficiency than FPA, with these results reversed under a looser budget constraint. Detailed patterns of bidding are compared to the theoretical predictions for both PA and FPA.

Collusive agreements in the form of corporate cartels are complex structures. The involved firms need to agree on terms that are legally not enforceable. However, the interplay between the involved firms in a collusive agreement, i.e., the governance dimension within a cartel, has received surprisingly low attention. Using a comprehensive OECD dataset of 191 cartels from 2012 to 2018, this paper empirically demonstrates how polycentric governance within a cartel may possibly contribute to understanding its stability. It may be beneficial for the duration and lower sanctions imposed by competition authorities, especially for large cartels. By that, the paper sheds new light on two aspects: the entangled governance structures of corporate cartels and the relevance of the concept of polycentricity beyond public administration.

We explore the changes in central government administration due to European Union (EU) membership and its consequences for policy outcomes and economic efficiency in Finland and Sweden. Both countries became members of the EU in 1995. Upon joining the union, member states are expected to adopt common legislation and are encouraged to develop similar rule-making procedures. The actual implementation of EU directives varies considerably between member states, however. This is also the case for Finland and Sweden. Despite the two Nordic countries for historical reasons having had similar government systems, upon becoming members of the EU, they started to diverge. Using a model of delegation and comparing the more centralized Finnish system with the decentralized institutional setup in Sweden, we show that the Swedish approach leads to a stricter than optimal environmental policy, which in turn makes EU policy non-optimal from a global point of view, ceteris paribus. We also provide empirical support for our findings in the form of some example cases. We focus on environmental policy since this is an area that has been high on the EU agenda.

A growing number of labour market participants transact through gig platforms. This choice should reflect a reduction in transaction costs for platform users, compared to costs they meet when using alternative modes of governance. We exploit a unique cross-platform, cross-country data set of gig platform users to test the impact of the institutional environment in one of its dimensions – the strictness of labour market regulation (LMR) – on the ability of gig platforms to reduce users' transaction costs. According to our findings, the regulation indicator of both the user and platform countries influences transaction costs for platform users, even controlling for platform and user characteristics. The platform appears to reduce transaction costs most when users face stricter or weaker LMR, in a U-shaped effect. In the former case, the platform may provide an escape from labour regulations when hiring for tasks, while in the latter case, the platform can economize on the usual transaction costs of private contracting by administrating some types of users' activities.

The presence of monitoring institutions affects quality and effort of leaders. We investigate the effect of intensified monitoring on the ability and effort of leaders for a sample of forest user groups in Ethiopia, and find experimental and non-experimental evidence of an important trade-off: monitoring increases leaders' effort but lowers their quality in terms of education and experience. This effort–ability trade-off only occurs in the presence of alternative income opportunities (affecting the opportunity cost of time) and only among a subsample of leaders with low prosocial motivation. For our context, we document that the net effect of monitoring on economic outcomes is positive.

Institutions matter for postdisaster recovery. Conversely, natural disasters can also alter a society's institutions. Using the synthetic control method, this study examines the effects that Hurricane Katrina (2005) had on the formal and informal institutions in Louisiana. As measures of formal institutions, we employ two economic freedom scores corresponding to government employment (GE) (as a share of total employment at the state-level) and property tax (PT). These measures serve as proxies for the level of governmental interference into the economy and the protection of private property rights respectively. To assess the impact on informal institutions, we use state-level social capital data. We find that Hurricane Katrina had lasting impacts on Louisiana's formal institutions. In the post-Katrina period, we find that actual Louisiana had persistently higher economic freedom scores for both GE and PT than the synthetic Louisiana that did not experience the hurricane. These findings imply that the hurricane led to a reduction in both PTs and GE, which indicates a decrease in the relative size of the public sector as a share of the state's economy. On the other hand, we find no impact on our chosen measure of informal institution.

In this article, we reconceptualize, using an extended discrete and dynamic Ostrom's classification, the specific intellectual property (IP) regimes that support geographical indications (GIs) as ‘knowledge commons’, e.g. a set of shared collective knowledge resources constituting a complex ecosystem created and shared by a group of people that has remained subject to social dilemma. Geographical names are usually considered part of the public domain. However, under certain circumstances, geographical names have also been appropriated through trademark registration. Our analysis suggests that IP laws that support GIs first emerged in Europe and spread worldwide as a response to the threat of undue usurpation or private confiscation through trademark registration. We thus emphasize the nature of the tradeoffs faced when shifting GIs from the public domain to shared common property regimes, as defined by the EU legislation pertaining to GIs. In the context of trade globalization, we also compare the pros and cons of regulating GIs ex-ante rather than engaging in ex-post trademark litigation in the courts.

Individuals often deem market transactions in sex, human organs and surrogacy, among others, repugnant. Repugnance norms can be explained by appealing to social-status concerns. We study an exchange economy in which agents abhor consumption dominance: one’s social status is compromised if one consumes less of every good than someone else does. Dominance may be forestalled by partitioning goods into submarkets and then invoking the repugnance norms that proscribe trade across these submarkets. Dominance may also be forestalled if individuals strategically ‘overconsume’ some goods, interpreted as emergent status goods. When equilibria are multiple, there is scope for welfare-enhancing policies that coordinate on status goods.

We present an experiment that sets up a context of production of a common output obtained by using production means that are randomly and unequally distributed. Before the production phase, subjects must choose a distributive principle for the output division, under ignorance of the allocation of the production means. Subsequently, they make a distributive choice fully aware of their luck and performance. The aim of the experiment is to test, first, whether ordinary subjects in an impartial situation are capable of converging on a fair principle of distribution – able of redressing the arbitrariness of the initial production means allocation; and second, whether these same ordinary subjects are capable of actually following that principle in a real distributive choice that excludes coercion, reputation effects and other forms of social pressures. The main finding is that a distributive rule that redresses initial inequalities is both accepted ex-ante and actually applied ex-post by most individuals. Our conclusion is relevant for the issue of realism of normative theories of justice and the possibility of institution design aimed at implementing distributive justice principles and policies.

All law is relatively coarse after its initial implementation as the legislature cannot foresee all contingencies that can arise in the actual application of the law. Therefore, decisions need to be made by street-level administrators as novel and particular circumstances arise. Economists have largely ignored the political science literature on street-level bureaucrats, such as policemen, welfare case managers, or regulatory agents. I present a case study in the context of market entry regulation in Germany. Qualitative and quantitative evidence suggests that bureaucratic discretion exists, that is, administrative actions can be found on different ends of a decision space, and that its effects are potentially large. Administrators do not apply legislation in a uniform manner and we observe a systematically different application of rules across subnational jurisdictions.

To what extent do imposed institutions shape preferences? We consider this issue by comparing the market-versus-state attitudes of respondents from a capitalist country, Finland, and from an ex-communist group of Baltic countries, and by arguing that the period of communist rule can be viewed as an ‘experiment’ in institutional imposition. We find that, consistent with some earlier related work, citizens from ex-communist countries tend to be more supportive of state ownership than respondents from capitalist economies. However, they also favour increasing inequality and competition as the means to enhance incentives. We conclude that, in some important relevant dimensions, institutional imposition (which lasted for about 50 years) had a limited effect on preferences.

Micro-econometric intra-cohort profitability analyses of pay-as-you-go (PAYG) pension contributions are rare. We use representative employment histories of German PAYG pension insurants retiring in year 2005 to examine the determinants of the profitability of contributions using nominal internal rates of return (IRR) as measure. When future nominal pension entitlements are frozen at today's level, average IRR is about three percent. It increases in beneficiaries' remaining life expectancies at retirement and in the length of non-contribution periods resulting, for example, from child care. Interestingly, IRR is decreasing in insurants' earnings capacity, indicating that the system entails an intra-cohort progressive element.
