We present a model of intuitive inference, called “local thinking,” in which an agent combines data received from the external world with information retrieved from memory to evaluate a hypothesis. In this model, selected and limited recall of information follows a version of the representativeness heuristic. The model can account for some of the evidence on judgment biases, including conjunction and disjunction fallacies, but also for several anomalies related to demand for insurance.

A central requirement in the design of a legal system is the protection of law enforcers from coercion by litigants through either violence or bribes. The higher the risk of coercion, the greater the need for protection and control of law enforcers by the state. Such control, however, also makes law enforcers beholden to the state, and politicizes justice. This perspective explains why, starting in the twelfth and thirteenth centuries, the relatively more peaceful England developed trials by independent juries, while the less peaceful France relied on state-employed judges to resolve disputes. It may also explain many differences between common and civil law traditions with respect to both the structure of legal systems and the observed social and economic outcomes.

We investigate cross-country determinants of private credit, using new data on legal creditor rights and private and public credit registries in 129 countries. Both creditor protection through the legal system and information-sharing institutions are associated with higher ratios of private credit to gross domestic product, but the former is relatively more important in the richer countries. An analysis of legal reforms shows that credit rises after improvements in creditor rights and in information sharing. Creditor rights are remarkably stable over time, contrary to the hypothesis that legal rules are converging. Finally, legal origins are an important determinant of both creditor rights and information-sharing institutions. The analysis suggests that public credit registries, which are primarily a feature of French civil law countries, benefit private credit markets in developing countries.

Countries differ significantly in the way in which they regulate the entry of new businesses. To meet government requirements for starting to operate a business in Austria, an entrepreneur must complete 12 procedures taking at least 154 business days and pay US$11,612 in government fees. To do the same, an entrepreneur in Bolivia needs to follow 20 different procedures, pay US$2,696 in fees to the government and wait at least 82 business days to acquire the necessary permits. In contrast, an entrepreneur in Canada can finish the process in roughly 2 days by paying US$280 in government fees and completing only 2 procedures.

When should a government provide a service in-house, and when should it contract out provision? We develop a model in which the provider can invest in improving the quality of service or reducing cost. If contracts are incomplete, the private provider has a stronger incentive to engage in both quality improvement and cost reduction than a government employee has. However, the private contractor's incentive to engage in cost reduction is typically too strong because he ignores the adverse effect on noncontractible quality. The model is applied to understanding the costs and benefits of prison privatization.

We investigate the regulation of labor markets through employment, collective relations, and social security laws in 85 countries. We find that the political power of the left is associated with more stringent labor regulations and more generous social security systems, and that socialist, French, and Scandinavian legal origin countries have sharply higher levels of labor regulation than do common law countries. However, the effects of legal origins are larger, and explain more of the variation in regulations, than those of politics. Heavier regulation of labor is associated with lower labor force participation and higher unemployment, especially of the young. These results are most naturally consistent with legal theories, according to which countries have pervasive regulatory styles inherited from the transplantation of legal systems.
