In recent decades, there has been an increase in the share of males struggling in the labor market and education. We show in a set of large-scale experimental studies involving more than 35,000 Americans that people are more accepting of males falling behind than they are of females falling behind, and less in agreement with government policies sup...

This paper leverages nationally representative surveys across 60 countries and 64,000 respondents to present novel stylized facts about the relationship-specific nature of altruism. Across individuals, universalist preferences systematically vary with demographics such as age and religiosity and are predictive of many left-wing political views, alb...

Background Adolescent pregnancies pose a risk to young mothers and their babies. In Zambia, one third of 18-year-old girls have given birth. Poverty, low secondary school enrolment, misinformation, and community norms contribute to early childbearing. We assessed the effectiveness of economic support alone and combined with comprehensive sexuality...

In a novel large-scale experiment, we study how adults in two societies, Shanghai (China) and Norway, make real distributive decisions involving children. We find that acceptance of inequality between children increases with the age of the children, is affected by the source of inequality and the cost of redistribution, and is lower than acceptance...

Consumers can sometimes be exploited because they make mistakes in their valuation of products. We present the results from a large-scale experimental study that examines whether third-party spectators from the general population in the United States cancel a voluntary deal where a buyer has made a mistake in the valuation of a product and agreed t...

To understand attitudes to inequality, we need to study people’s fairness preferences and beliefs about the sources of inequality. This article reviews the existing experimental literature on fairness, including our new study ‘Fairness Across the World’ that collected novel data on attitudes to inequality in 60 countries. We establish that people i...

A main focus in economics is how to design optimal policies in second-best situations, which often requires a trade-off between giving some individuals more than they deserve, false positives, and others less than they deserve, false negatives. This paper provides novel evidence on people’s second-best fairness preferences from large-scale experime...

Village savings and loans associations (VSLAs) are promoted as an important tool for economic and social empowerment, primarily targeting women. However, there is relatively limited evidence on the impact of VSLAs, and no evidence on whether such programs work better for some groups than for others. Using a large-scale field experiment on a VSLA ta...

A long history in economics going back to Adam Smith has argued that people give primacy to merit – rather than luck – in distributive choices. We provide a theoretical framework formalizing the merit primacy effect, and study it in a novel experiment where third-party spectators redistribute from high-earners to low-earners in situations where bot...

We report from a study of how uncertainty about whether a given inequality reflects performance or luck shapes distributive behaviour. We show theoretically that the reaction to uncertainty depends on how people trade off the probability of making a mistake when redistributing, and the size of this mistake. We show experimentally that uncertainty c...

Human behaviour is complex and multifaceted, and is studied by a broad range of disciplines across the social and natural sciences. To mark our 5th anniversary, we asked leading scientists in some of the key disciplines that we cover to share their vision of the future of research in their disciplines. Our contributors underscore how important it i...

Significance People’s beliefs about why the rich are richer than the poor have the potential to affect both policy attitudes and economic development. We provide global evidence showing that where the fortunes of the rich are perceived to be the result of selfish behavior, inequality is viewed as unfair, and there is stronger support for income red...

We conduct an intercultural experiment in three locations on three different continents to elicit competitiveness and study whether individual differences in competitiveness are related to handedness. Being a “lefty” (i.e., having either a dominant left hand or a dominant left foot) is associated with neurological differences which are determined p...

In a large-scale pre-registered survey experiment with a representative sample of more than 8000 Americans, we examine how a reminder of the COVID-19 pandemic causally affects people’s views on solidarity and fairness. We randomly manipulate whether respondents are asked general questions about the crisis before answering moral questions. By making...

Elections affect the division of resources in society and are occasions for political elites to make appeals rooted in voters' self-interest. Hence, elections may erode altruistic norms and cause people to behave more selfishly. We test this intuition using Dictator Games in a lab-in-the-field experiment involving a sample of more than 1000 individ...

Value added tax (VAT) is one of the main modes of raising tax revenue worldwide but has significantly underperformed as a revenue collection tool in Africa. Non-compliance by taxpayers is a major challenge. This Misum Academic Insight explores the extent to which Tanzanian businesses are VAT compliant and the factors explaining compliance. Practic...

The principle that people should be held personally responsible for the consequences of their choices is a fundamental moral ideal in Western societies. We report from a large-scale experimental study of how far-reaching this principle is for inequality acceptance. We show that third-party spectators violate minimal conditions for a morally relevan...

Can television be used to teach and foster entrepreneurship among youth in developing countries? We report from a randomized control field experiment of an edutainment show on entrepreneurship broadcasted over almost three months on national television in Tanzania. The field experiment involved more than 2,000 secondary school students, where the t...

Humans are social beings, and acts of prosocial behavior may be influenced by social comparisons. To study the development of prosociality and the impact of social comparisons on sharing, we conducted experiments with nearly 2500 children aged 3-12 years across 12 countries across five continents. Children participated in a dictator game where they...

We report from a large-scale randomized field experiment conducted on a unique sample of more than 15,000 taxpayers in Norway who were likely to have misreported their foreign income. By randomly manipulating a letter from the tax authorities, we cleanly identify that moral suasion and the perceived detection probability play a crucial role in shap...

We present results from the first study to examine the causal impact of early childhood education on the social preferences of children. We compare children who, at 3-4 years old, were randomized into either a full-time preschool, a parenting program, or a control group. We returned to the children when they reached 6-8 years of age and conducted a...

There are striking differences in inequality and redistribution between the United States and Scandinavia. To study whether there are corresponding differences in social preferences, we conducted a large-scale international social preference experiment where Americans and Norwegians make distributive choices in identical environments. Combining the...

Ethnicity has been shown to shape political, social, and economic behavior in Africa, but the underlying mechanisms remain contested. We utilize lab experiments to isolate one mechanism—an individual's bias in favor of coethnics and against non-coethnics—that has been central in both theory and in the conventional wisdom about the impact of ethnici...

As a result of widespread mistreatment and overt discrimination in all dimensions of their lives, women lack significant autonomy. The central preoccupation of this book is to explore key sources of female empowerment and discuss the current challenges and opportunities for the future. Schematically, three main domains are distinguished. The first...

The pari passu principle of awarding claimants proportionally to their pre-insolvency claims is the most prominent principle in the law of insolvency. We report from a lab experiment designed to study whether people find this principle a fair solution to the bankruptcy problem. The experimental design generates situations where participants work an...

Chapter 6 discusses the implications of a liberal egalitarian approach to tax policy and argues that such an approach avoids two fundamental challenges faced by the standard welfarist approach: the “exploitation of the hard-working” and the “exploitation of the talented.” It is also argued that the liberal egalitarian approach is able to capture th...

The paper reports the first experimental study on people’s fairness views on extreme income inequalities arising from winner-take-all reward structures. We find that the majority of participants consider extreme income inequality generated in winner-take-all situations as fair, independent of the winning margin. Spectators appear to endorse a “fact...

In recent years, many countries have faced pressure to cut the costs of the welfare state, and different strategies have been utilized to achieve this, including stricter eligibility requirements, reduced level of benefits, and reduced maximum duration of benefits. This contribution reports the results from a Norwegian survey designed to measure wh...

Corruption appears to be an important driver of the resource curse in developing countries. We report from a large-scale field experiment in Tanzania that provides causal evidence on how expectations about future natural resource revenues shape expectations about corruption and the willingness to engage in corrupt behavior. We find robust evidence...

How should income be distributed in a way that respects both the egalitarian ideal that inequalities due to differences in opportunities should be eliminated and the liberal ideal that people should be free to pursue their own idea of the good life without interference from society? We show that reasonable interpretations of the egalitarian and the...

We study the relative importance of intrinsic moral motivation and extrinsic social motivation in explaining moral behavior. The key feature of our experiment is that we introduce a dictator game design that manipulates these two sources of motivation. In one set of treatments, we manipulate the moral argument for sharing, in another we manipulate...

Background: Adolescent pregnancies pose a risk to the young mothers and their babies. In Zambia, 35% of young girls in rural areas have given birth by the age of 18 years. Pregnancy rates are particularly high among out-of-school girls. Poverty, low enrolment in secondary school, myths and community norms all contribute to early childbearing. This...

In this paper we provide new evidence showing that fair behavior is intuitive to most people. We find a strong association between a short response time and fair behavior in the dictator game. This association is robust to controls that take account of the fact that response time might be affected by the decision-maker’s cognitive ability and swift...

This paper studies the role of family background in explaining differences in the willingness to compete in a cognitive task. By combining data from a lab experiment conducted with a fairly representative sample of adolescents in Norway and high-quality register data on family background, we show that family background is fundamental in two importa...

We study how leader compensation affects public goods provision. We report from a lab experiment with four treatments, where the base treatment was a standard public goods game with simultaneous contribution decisions, and the three other treatments allowed participants to volunteer to be the leader in their group and make their contribution before...

We exploit a unique data set, combining rich experimental data with high-quality administrative data, to study dropout from the college track in Norway, and why boys are more likely to drop out. The paper provides three main findings. First, we show that family background and personal characteristics contribute to explain dropout. Second, we show t...

Huge reservoirs of natural gas have been discovered offshore the southern coast of Tanzania. There are high expectations that exploitation of natural resources will substantially increase Tanzania’s national income. This brief presents results from a recent survey experiment of 3000 respondents in Dar es Salaam, Mtwara and Lindi regions. We find th...

Fairness preferences fundamentally affect individual behavior and play an important role in shaping social and political institutions. However, people differ both with respect to what they view as fair and with respect to how much weight they attach to fairness considerations. In this article, we study the role of family background in explaining th...

What ethical criterion for intergenerational justice should be adopted, e.g., when faced with the task of managing the global environment? Koopmans ’ axiomatization of discounted utilitarianism is based on seemingly compelling conditions, yet this criterion leads to hard-to-justify outcomes. The present analysis considers a class of sustainable rec...

Hvilke ulikheter oppfattes som rettferdige? Vi presenterer resultatet fra en surveyundersøkelse med et nasjonalt representativt utvalg av den norske befolkningen. Hovedfunnet er at nordmenn synes ulikheter kan være både rettferdige og urettferdige avhengig av hvilke forhold ulikhetene skyldes: Mens nordmenn er kritiske til ulikheter som skyldes fla...

When forming their preferences about the distribution of income, rational people may be caught between two opposite forms of “tyranny.” Giving absolute priority to the worst-off imposes a sort of tyranny on the rest of the population, but giving less than absolute priority imposes a reverse form of tyranny where the worst-off may be sacrificed for...

More than one billion people in the world have some kind of disability. Apart from the obvious physical challenges facing disabled people, there may also be psychological barriers that make it difficult for them to integrate in society and prosper. These challenges may be particularly difficult in developing countries, where disabled individuals ar...

We report from a lab experiment designed to study whether People find this principle a fair solution to the bankruptcy problem. The experimental design generates situations where participants work and accumulate claims in firms, some of which subsequently go bankrupt...

Significance People’s preferences for income distribution fundamentally affect their behavior and contribute to shaping important social and political institutions. The study of such preferences has become a major topic in behavioral research in social psychology and economics. Despite the large literature studying preferences for income distributi...

Hjernen har lenge vært en sort boks for økonomer, men i økende grad har økonomer begynt å studere hvilke mentale prosesser som ligger bak folks valg. Ikke minst forsøker man å forstå hvorfor folk noen ganger velger å gjøre det de oppfatter som rettferdig, selv om det går på bekostning av deres økonomiske egeninteresse. Er vi predisponert for å oppt...

We report an experimental test of the four touchstones of rationality in choice under risk – utility maximization, stochastic dominance, expected-utility maximization and small-stakes risk neutrality – with students from one of the best universities in the United States and one of the best universities in Africa, the University of Dar es Salaam. Al...
