In this paper we investigate the e�ect of the absence of a secret ballot on electoral outcomes and resource allocation. Once voting behavior is observable, votes can be bought and sold in a `market for votes'. We distinguish between direct vote buying, where individuals sell their own votes to political parties, and indirect vote buying, where people also sell the votes of others and we characterized the circumstances in which vote buying changes the electoral outcome. We then provide a microfoundation for indirect vote buying, which usually takes the form of employers selling the votes of their employees. This can oc- cur when the employment relationship involves rents since employers can use the threat of withdrawal of these rents to control the political behavior of their work- ers. This increases the demand for labor and generates an added incentive to own land, increasing the price of land. We test the predictions of the model by examining in detail the eff�ects of the introduction of the secret ballot in Chile in 1958. We show that this change in political institutions had implications for voting behavior and land prices which are consistent with the predictions of our model.

The rapid decline of German emigration before World War I constitutes a puzzle that traditional explanations (decrease in the international wage gap, growing industrialization, fall in the fertility or international competition with other migrants) can only partly solve. It therefore seems necessary to go more deeply into the question, in particular by looking into the social legislation implemented by Bismarck during the 1880s. Actually, the German insurance system was one of the most developed in the pre-1914 world and it probably contributed to deterring labor outflows. The main explanation is that candidates for migration consider not only the gap between direct wages in sending and receiving countries, but also the differential in “indirect wages”, that is, social benefits. As a matter of fact, the existence of such benefits constitutes a form of social remuneration that partly offsets low levels of wage rates in sending countries. In that perspective, the econometric tests run in the paper show that the increase in German indirect wages after 1885 was accompanied by a significant decrease in emigration rates.

Previous research in economics shows that paying the agent based on performance induces the agent to exert more effort thereby enhancing productivity. On the other hand, research in psychology argues that performance-based financial incentives may inhibit creativity and innovation. In a controlled laboratory experiment, we provide evidence that the combination of tolerance for early failure and reward for long-term success is effective in motivating innovation. Subjects under such an incentive scheme explore more and are more likely to discover a novel business strategy than subjects under fixed-wage and standard pay-for-performance incentive schemes. We also find evidence that the threat of termination can undermine incentives for innovation, while golden parachutes can alleviate these innovation-reducing effects. Our results suggest that appropriately designed incentives are useful in motivating creativity and innovation.

Social norms have the potential to alter the functioning of economic markets. We test whether norms shape the aggregate labor supply curve by preventing workers from supplying labor at wage cuts—leading decentralized individuals to implicitly behave as a cartel to maintain wage floors in their local labor markets. We partner with 183 existing employers, who offer jobs to 502 workers in informal spot labor markets in India. Unemployed workers are privately willing to accept jobs below the prevailing wage, but rarely do so when this choice is observable to other workers. In contrast, social observability does not affect labor supply at the prevailing wage. Workers give up 49% of average weekly earnings to avoid being seen as breaking the social norm. In addition, workers pay to punish anonymous laborers who have accepted wage cuts—indicating that cartel behavior is reinforced through the threat of social sanctions. Punishment occurs for workers in one’s own labor market and for those in distant regions, suggesting the internalization of norms in moral terms. Finally, consistent with the idea that norms could have aggregate implications, measures of social cohesion correlate with downward wage rigidity and business cycle volatility across India.

The impact of ethnic diversity on the provision of local public goods and collective action in Africa remains largely unexplored. To address this gap, this paper explores the relationship between ethnic diversity and local primary school funding in rural western Kenya. The econometric identification strategy relies on the stable, historically determined patterns of ethnic land settlement in western Kenya. The main empirical result is that higher levels of local ethnic diversity is associated with sharply lower primary school funding and worse school facilities in western Kenya. The theory examines school choice and funding decisions when pupil mobility among schools is limited by land market imperfections and ethnic divisions, the relevant case for rural Africa, and predicts that local pupil transfers may lead to upward bias in OLS estimates of the impact of ethnic diversity. This theoretical prediction is confirmed in the data.

The COVID-19 pandemic has upended health and living standards around the world. This article provides an interim overview of these effects, with a particular focus on low- and middle-income countries (LMICs). Economists have explained how the pandemic is likely to have different consequences for LMICs and demands distinct policy responses compared to those of rich countries. We survey the rapidly expanding body of empirical research that documents the pandemic's many adverse economic and noneconomic effects in terms of living standards, education, health, and gender equality, which appear to be unprecedented in scope and scale. We also review research on successful and failed policy responses, including the failure to ensure widespread vaccine coverage in many LMICs, which is needed to end the pandemic. We close with a discussion of implications for public policy in LMICs and for the institutions of international governance, given the likelihood of future pandemics and other major shocks (e.g., climate).
