Summary: This study examines poor farmers' access to agricultural cooperatives and the impact of membership on farm and total household income. Factors such as family ethnicity, neighborhood, land size, proximity to a cooperative, distance to the local market, and access to a motorable road influence cooperative membership. The analysis suggests that cooperative membership may significantly affect family net crop income, but the overall effects on total family income are modest.

Summary: Community groups are adapting to climate change through collective action, utilizing positive reinforcement methods and few punishments. These organizations differ from businesses and governments, but still address common pool resource issues. This article examines how community groups solve collective action problems and discusses implications for collective action theory and climate change policymaking.

Summary: The diseconomies of scale in smallholders' agricultural production is a common problem in global agricultural development, particularly in regions such as Central and Eastern Europe, India, Brazil, and China. The scattered farmland, diverse soil conditions, different crop varieties, and various farming arrangements make it difficult for smallholders to cooperate on farmland scale management, resulting in a collective action dilemma. This study provides insights into the factors and effects of smallholders' utilization of socialized agricultural services and proposes a cooperative mechanism to solve the collective action dilemma in rural areas of China.

Summary: Worker cooperatives have a crucial role in alleviating the adverse effects of capitalism and are seen as potential spaces for social transformation. This article examines the process of political subjectivation within the framework of collective work, using concepts of subalternity, antagonism, and autonomy. The study of Uruguayan cooperatives reveals the characteristics and factors that contribute to the formation of different types of cooperatives.

Summary: This study highlights the challenges smallholders and farmworkers in the global South face in global agricultural value chains, where highly concentrated global wholesalers and retailers have significant leverage over them. Social upgrading opportunities are limited for producers, except for cooperatives. The article emphasizes the role of the state in promoting social upgrading.

Summary: This study proposes a test approach based on penalized phi-divergences to address the model selection problem for multinomial data. By deriving the null distribution and providing decision rules, it is possible to determine which model better explains the available data. The practical behavior of the approach is evaluated through simulation experiments and applied to a real data set related to social preference classification.

Summary: This paper examines the problem of testing for the equality of distributions of k independent samples with finite but arbitrary dimension, providing the asymptotic distribution of two test statistics under the null hypothesis and under alternatives. Both test statistics are shown to be asymptotically free distributed under the null hypothesis. The finite sample performance of the tests based on the asymptotic null distribution is studied through simulation, with an application to a real data set included.

Summary: The standard approach in Economics views nominal illusion as transient, but recent empirical studies suggest it may persist, distorting real prices. An experimental study shows a significant impact of nominal exchange rates on market prices, possibly due to players simplifying decision-making through discrete choices.

Summary: This study investigates rewards-based crowdfunding as an innovative financing form for startups and firms, testing hypotheses about the positive effects of funding target and number of rewards on market size. The research findings show that both funding target and number of rewards positively influence market size, with significant mediating roles of social networks and backers' preferences in explaining these relationships. Additionally, the orientation of a crowdfunding campaign, whether commercial or social, is relevant in determining the effectiveness of high funding targets and high numbers of rewards in different types of projects.

Summary: This study conducted an experiment with ex-combatants, victims, and non-victims of conflict in Colombia, examining their contributions to a public good. The results show that victims and non-victims discriminate more against ex-combatants compared to each other, and this discrimination is preference-based rather than belief-based.

Summary: This study analyzes the behavioral determinants of extreme punishment in intergroup conflict. The results suggest that political inequality is more likely to lead to extreme intergroup punishment compared to economic inequality. Additionally, individuals with higher skills are more likely to sacrifice themselves to harm the other group.

Summary: This study examines the impact of voter and platform polarization on political participation and the political inclusion of others in Colombia. Experimental results indicate that the polarization of platforms does not increase willingness to engage in politics or include others in the political process. However, the endogenous polarization of participants plays a significant role in shaping their preferences for political participation and inclusion.

Summary: A randomised field experiment was conducted at the University of Malaga in 2017 to examine the effects of personalised norm-based messages on response rates to the annual faculty satisfaction survey. The results showed that the informal-moral duty and informal-social norm treatments had the strongest positive effect.

Summary: This research experimentally examines how different contextual frames influence competitive behavior in a Bertrand duopoly game. The findings show that differences across frames eventually vanish at the end, and during the transition, a quicker decay in prices is observed in the Bertrand frame.

Summary: This paper investigates the impact of inter- and intragroup heterogeneity on intergroup coordination. The experimental results show that vertical heterogeneity, accompanied by intragroup homogeneity, does not hinder groups' ability to coordinate and maintain high performance. The findings suggest that group dynamics are influenced by the distributional preferences and cooperative behavior of initially less cooperative groups. These findings have implications for the design of incentives and governance in organizations and societies.

Summary: This article discusses a two-player sequential game where players first choose between engaging in a productive or unproductive activity, and then, if both players choose to enter the market, they compete in prices. The two economic activities are linked as the rents in the contest game are a fraction of the market profits. Experimental results reject the prediction based on backward induction but can be explained by forward induction arguments. The payoffs from the rent-seeking activity influence pricing behavior and prices do not converge to marginal costs. When the size of the rent-seeking activities is large, firms coordinate better and prices converge to full collusion in market competition.

Summary: Competition between groups that are not created equal intensifies conflict and increases volatility, leading to reduced earnings for contest participants and increased inequality. Heterogeneous groups share labor more equally than predicted by theory, and in asymmetric contests, group members change how they condition their efforts on those of their peers.
