In-group bias can be detrimental for communities and economic development. We study the causal effect of financial constraints on in-group bias in prosocial behaviors – cooperation, norm enforcement, and sharing – among low-income rice farmers in rural Thailand, who cultivate and harvest rice once a year. We use a between-subjects design – randomly assigning participants to experiments either before harvest (more financially constrained) or after harvest. Farmers interacted with a partner either from their own village (in-group) or from another village (out-group).

Nearly all students experience stress as they pursue important academic goals. Because stress can be magnified for students from disadvantaged backgrounds, it becomes important to identify interventions that can help mitigate this stress, particularly for these populations as they enter academic environments. We examine the effects of stress mindset and stress management interventions administered to students from disadvantaged backgrounds (N = 140) before freshman year.

This paper shows that providing undocumented immigrants with an immigration pardon, or amnesty, increases their economic activity in the form of higher entrepreneurship. Using administrative census data linked to the complete formal business registry, we study a 2018 policy shift in Colombia that made nearly half a million Venezuelan undocumented migrants eligible for a pardon. Our identification uses quasi-random variation in the amount of time available to get the pardon, introducing a novel regression discontinuity approach to study this policy.

Despite the skyrocketing of sustainability-related research in the strategy and management fields, there has been no comprehensive systematic review of the field as a whole. In this paper, we present a comprehensive review of the field of corporate sustainability using a science mapping co-word bibliometric analysis. Through analysis of the co-occurrence of 25,701 keywords in 11,962 sustainability-related articles from 1994-2021, we identify and graphically illustrate the thematic and theoretical evolution of the field, in addition to emerging and waning research trends in the field.

The early stages of the COVID-19 pandemic revealed stark regional variation in the spread of the virus. While previous research has highlighted the impact of regional differences in sociodemographic and economic factors, we argue that regional differences in social and compliance behaviors-the very behaviors through which the virus is transmitted-are critical drivers of the spread of COVID-19, particularly in the early stages of the pandemic.

The financial crisis of 2007–2008 was the most serious since the Great Depression and severely impacted the global economy. Yet more than 10 years after the crisis, we still lack clear understanding of its cause. Accounts point to some elements of fact but tend to be fragmented and sometimes contradictory. More than ever, we need an account that can put the puzzle pieces together and help us understand how to prevent a crisis like this from happening again.

Performance expectations are revisited pertaining to particular corporate strategies that were highlighted by Rumelt (1974). In particular, suggestions regarding expectations about conglomerate enterprises, vertical integration, and mature- or declining-demand businesses are offered in light of additional information about research findings and observed industry phenomena that are at odds with information available when Rumelt's (1974) study of diversification was performed.
