Knowledge that Transforms

Government regulation of firms is associated with more negative externalities and unofficial activity across countries. I argue that this correlation mainly reflects causality going from concerns about market failures to demand for government intervention. Using trust in others as a proxy for such concerns, I show that differences in trust explain a great deal of variation in entry regulations. Then, controlling for trust in the regression of market failures on regulation, the latter is no longer associated with worse economic outcomes. The same result is confirmed when I exploit country population as an alternative source of variation in regulation.

Female entrepreneurs may be less networked than their male counterparts and so derive less benefit from agglomeration. They may also have greater domestic burdens and therefore have higher commuting costs. This paper develops a theoretical model showing that either of these forces can lead to the segregation of male- and female-owned businesses, with female entrepreneurs choosing locations farther from agglomerations and commuting shorter distances. Empirical analysis is consistent with these predictions. Female-owned businesses are segregated, often to a degree similar to black-white residential segregation. Female-owned enterprises are less exposed to agglomeration, with 10% to 20% less own-industry employment nearby.

We use data from a Brazilian social program to investigate the existence of gender bias in intrahousehold allocations of resources. The program makes cash transfers to mothers and pregnant women in poor households. Bureaucratic mistakes, beyond the control of the applicants, have inadvertently excluded many households that had applied and were accepted to the program. This unintentional natural experiment is used to identify the impact of an exogenous variation in female nonlabor income over household consumption. We find that program participation led to an increase in food expenditure, but this effect is not due to women being the benefit recipients.

Using cross-state variation in minimum wages, we observe a positive relationship between the minimum wage and the number of alcohol-related accidents involving teen drivers. A similar effect is not observed when examining accidents among adults. The results are consistent with a positive income elasticity for alcoholic beverages and driving activities among young people, in particular for consumption out of discretionary income accorded by higher minimum wages. Evidence of a sizable impact of beer taxes on alcohol-related accidents among youths suggests that beer taxes are one avenue for policymakers to consider in counteracting this unintended consequence of minimum wages.

Using a method-of-moments estimator, flexible three-parameter beta distributions are fitted to aggregate country-level income data to overcome an untenable assumption of previous studies that persons within each income group receive the same income. Regional and global income distributions are derived as weighted mixtures of country-specific distributions. Analytical expressions for Gini and Theil's measures of inequality at country, regional, and global levels are derived in terms of the parameters of the beta distributions. Application to data for 91 countries in 1993 and 2000 reveals a high degree of global inequality, with evidence of declining inequality, largely attributable to growth in China.

In 2007, the Consumer Product Safety Commission issued 212 recalls of toys and other children's products, a sizable increase from previous years. We investigate changes in toy sales following these recalls. We find that for manufacturers that had recalls, unit sales of the types of toys involved in the recall fell relative to their sales of toys in other categories. We do not find evidence of within-manufacturer spillovers to dissimilar toys. We do, however, find large industry-wide spillovers in the form of sales losses to manufacturers that did not experience any recalls. Our results shed light on how consumers may draw inferences from information about product safety.

This paper investigates whether patent applicants strategically withhold citations to material prior art. Citation data suggest that applicants withhold between 21% and 33% of relevant citations. Variation in withholdings is explained by patent portfolio size and indicators of patent value. These data also highlight important differences across technology classes. In particular, firms are significantly less likely to withhold a citation when applying for chemical and drug patents. Robustness checks confirm that these results are not explained by inventor and attorney familiarity with citations, patent examiner heterogeneity, or the nationality of the inventor.

We model the interrelations of equity market volatility in eight East Asian countries before, during, and after the Asian currency crisis. Using a new class of asymmetric volatility multiplicative error models based on the daily range, we find that dynamic propagation of volatility shocks occurs through a network of interdependencies, and shocks originating in Hong Kong may be amplified in their transmission throughout the system, posing greater risks to the region than shocks originating elsewhere. Although this partly explains the severity of the currency crisis, we also find evidence that parameters shifted, making the system more unstable during the crisis.

This paper analyzes how electoral incentives affected the performance of a major decentralized conditional cash transfer program intended on reducing school dropout rates among children of poor households in Brazil. We show that while this federal program successfully reduced school dropout by 8 percentage points, the program's impact was 36% larger in municipalities governed by mayors who faced reelection possibilities compared to those with lame-duck mayors. First-term mayors with good program performance were much more likely to be reelected. These mayors adopted program implementation practices that were not only more transparent but also associated with better program outcomes.

Using controlled experiments, we examine how individuals make choices when faced with multiple options. Choice tasks are designed to mimic the selection of health insurance, prescription drug, or retirement savings plans. In our experiment, available options can be objectively ranked allowing us to examine optimal decision making. First, the probability of a person selecting the optimal option declines as the number of options increases, with the decline being more pronounced for older subjects. Second, heuristics differ by age with older subjects relying more on suboptimal decision rules. In a heuristics validation experiment, older subjects make worse decisions than younger subjects.
