Knowledge that Transforms

In earlier work we identified a robust negative association between religiosity and patents per capita, holding across countries as well as US states. In this paper we relate 11 indicators of individual openness to innovation (e.g., attitudes toward science and technology, new versus old ideas, change, risk taking, agency, imagination, and independence in children) to 5 measures of religiosity, including beliefs and attendance. We use five waves of the World Values Survey and control for sociodemographics, country and year fixed effects. Across the 52 regressions, greater religiosity is almost uniformly associated to less favorable views of innovation, with high significance.

I examine the effects that the 1986 Immigration Reform and Control Act (IRCA), which legalized almost 3 million immigrants, had on crime in the United States. I exploit the IRCA's quasi-random timing as well as geographic variation in the intensity of treatment to isolate causal impacts. I find decreases in crime of 3-5 percent, primarily due to decline in property crimes, equivalent to 120,000-180,000 fewer violent and property crimes committed each year due to legalization. I calibrate a labor market model of crime, finding that much of the drop in crime can be explained by greater labor market opportunities among applicants.

We estimate a model of importers in Hungarian microdata and conduct counterfactual analysis to investigate the effect of imported inputs on productivity. We find that importing all input varieties would increase a firm’s revenue productivity by 22 percent, about one-half of which is due to imperfect substitution between foreign and domestic inputs. Foreign firms use imports more effectively and pay lower fixed import costs. We attribute one-quarter of Hungarian productivity growth during the 1993–2002 period to imported inputs. Simulations show that the productivity gain from a tariff cut is larger when the economy has many importers and many foreign firms.

Individuals must often choose among discrete actions with imperfect information about their payoffs. Before choosing, they have an opportunity to study the payoffs, but doing so is costly. This creates new choices such as the number of and types of questions to ask. We model these situations using the rational inattention approach to information frictions. We find that the decision maker's optimal strategy results in choosing probabilistically in line with a generalized multinomial logit model, which depends both on the actions' true payoffs as well as on prior beliefs.

Previous work demonstrates that low-income higher achievers fail to apply to selective colleges despite their being admitted at high rates and receiving financial aid so generous that they pay less than at non-selective schools. The Expanding College Opportunities project, a randomized controlled trial, provides individualized information about colleges' net prices, resources, curricula, students, and outcomes. Our prior study shows that the intervention raises students' applications to, admissions at, enrollment, and progress at selective colleges. Here we use survey data to show that it actually changes students' knowledge and decision-making. We highlight topics on which they are misinformed.

We use microdata to show that young households with children are underinsured against the risk that an adult member of the household dies. This empirical finding can be explained by a macroeconomic model with human capital risk, age-dependent returns to human capital investment, and endogenous borrowing constraints due to limited contract enforcement. When calibrated, the model quantitatively accounts for the observed life-cycle variation in life insurance holdings, financial wealth, earnings, and consumption inequality. The model also predicts that reforms making consumer bankruptcy more costly will substantially increase the volume of both credit and insurance.

Using data from an anti-vote-buying field experiment we conducted in the Philippines, we report and validate a proxy measure for vote-selling. We demonstrate that our proxy measure, vote-switching, changes as expected with voter preferences and monetary offers from candidates. Voters are less likely to vote for someone different than their initial preference the larger the favorability rating difference between the preferred and alternative candidates. Similarly, vote-switching increases the more money the alternative candidate offers compared to the preferred candidates. We also describe the effects of the promise-based interventions on vote-switching, reported in full in a companion paper.

Countercyclical risk aversion can explain major puzzles such as the high volatility of asset prices. Evidence for its existence is, however, scarce because of the host of factors that simultaneously change during financial cycles. We circumvent these problems by priming financial professionals with either a boom or a bust scenario. Subjects primed with a financial bust were substantially more fearful and risk averse than those primed with a boom, suggesting that fear may play an important role in countercyclical risk aversion. The mechanism described here is relevant for theory and may explain self-reinforcing processes that amplify market dynamics.

This paper examines frictions in contract renegotiation and its implications for allocative efficiency of contracts. Using a novel audit study methodology, we find that contracting parties in general are reluctant to engage in hold up. However, many efficient renegotiations of contracts also do not happen for the fear of being seen as extracting surplus. We also find that ex ante contracts are structured to mitigate losses arising from breach risk rather than hold up. The results also highlight that role of norms of fairness and reputation concerns in sustaining transactions in settings where contracts are primarily incomplete.

Andreoni and Sprenger (2012a, b) report evidence that distinct utility functions govern choices under certainty and risk. I investigate the robustness of this result to the experimental design. I find that the effect disappears completely when a multiple price list instrument is used instead of a convex time budget design. Alternatively, the effect is reduced by half when sooner and later payment risks are realized using a single lottery instead of two independent lotteries. The result is thus at least partially driven by intertemporal diversification, supporting an explanation in terms of concavity of the intertemporal, and not only atemporal, utility function.
