Knowledge that Transforms

This paper identifies an exogenous variation in post–Civil War policy to examine the effect of land reform on racial inequality. The Cherokee Nation, located in what is now Oklahoma, permitted slavery and joined the Confederacy in 1861. During postwar negotiations, the Cherokee Nation agreed to provide free land for its former slaves. Using linked data that follow former slaves in the Cherokee Nation from 1880 to 1900, I find that racial inequality was lower in the Cherokee Nation in both 1880 and 1900. Land and the associated increase in incomes may have facilitated investment in both physical and human capital.

Abstract We estimate the causal effects of education on the intergenerational transmission of violence against children by exploiting an extension of compulsory schooling in Turkey. Using a regression-discontinuity design, we find that the reform increased maternal education by one year, with stronger effects for women raised in rural areas. The increase in education among rural women led to a reduction in the perpetration of child physical abuse but only by mothers who were physically abused by their own families during childhood. Exploring potential channels, we document that these women were also more likely to experience improved mental health outcomes.

Technology adoption often requires multiple stages of investment. As new information emerges, agents may abandon a technology that was profitable in expectation. We use a field experiment to vary the payoffs at two stages of investment in a new technology: a tree species that provides on-farm fertilizer benefits. Farmer decisions identify the information about profitability that arrives between the take-up and follow-through stages. Results show that this form of uncertainty increases take-up but lowers average tree survival, decreasing the cost-effectiveness of take-up subsidies. Thus, uncertainty offers another explanation for why even costly technologies may go unused or be abandoned.

We use novel quarterly data of U.S. states to examine the dynamics of relative spending multipliers in the decade surrounding the Great Recession. While multipliers were around 1 in expansions, they reached values above 4 when a state was in a recession. Also a high (low) degree of household indebtedness augmented (lowered) a state's multiplier by 0.5 in expansions and 2 in recessions. We further document modest positive spillover effects across states and show that a mere redistribution of spending across states also had a significant influence on the aggregate U.S. economy due to cross-state heterogeneity of the effects.

We estimate uncertainty measures for point forecasts obtained from survey data, pooling information embedded in observed forecast errors for different forecast horizons. To track time-varying uncertainty in the associated forecast errors, we derive a multiple-horizon specification of stochastic volatility. We apply our method to forecasts for various macroeconomic variables from the Survey of Professional Forecasters. Compared to simple variance approaches, our stochastic volatility model improves the accuracy of uncertainty measures for survey forecasts.

We evaluate the temporal stability of risk preferences using a remarkable data set that combines sociodemographic information from the Danish Civil Registry with information on risk attitudes from a longitudinal field experiment. Our econometric model accounts for endogenous sample selection and attrition processes that may confound inferences about temporal stability. Our experimental design builds in randomization on the incentives for participation that facilitates empirical identification of the model. In general, we find evidence consistent with temporal stability after correcting for the effects of selection and attrition. When neglected, these effects change our inferences in an economically and statistically significant manner.

Affirmative action raises the likelihood of getting into college or obtaining a government job for minority social groups in India. I find that minority group students are incentivized to stay in school longer in response to changes in future prospects. To identify causal relationships, I leverage variation in group eligibility, school age cohorts, and state-level intensity of implementation in difference-in-differences and regression discontinuity designs. These estimators consistently show that affirmative action incentivizes about 0.8 additional years of education for the average minority group student and 1.2 more years of education for a student from a marginal minority subgroup.

We estimate the impact of youth minimum wages on youth employment by exploiting a large discontinuity in Danish minimum wage rules at age 18, using monthly payroll records for the Danish population. The hourly wage jumps by 40% at the discontinuity. Employment falls by 33%, and total input of hours decreases by 45%, leaving the aggregate wage payment almost unchanged. We show theoretically how the discontinuity may be exploited to evaluate policy changes. The relevant elasticity for evaluating the effect on youth employment of changes in their minimum wage is in the range 0.6 to 1.1.

In this paper, we estimate the costs associated with an important suite of labor regulations in India by taking advantage of the fact that these regulations apply only to firms above a size threshold. Using distortions in the firm size distribution together with a structural model of firm size choice, we estimate that the regulations increase firms' unit labor costs by 35%. This estimate is robust to potential misreporting on the part of firms and enumerators. We also document a robust positive association between regulatory costs and exposure to corruption, which may explain why regulations appear to be so costly in developing countries.

Using survey data from a representative sample of Dutch households, we estimate the strength of precautionary saving by eliciting subjective expectations on future consumption. Expected consumption risk is positively correlated with self-employment and income risk and negatively with age. We insert these subjective expectations (rather than consumption realizations, as in the existing literature) in an Euler equation for consumption and estimate the degree of prudence by associating expected consumption risk with expected consumption growth. Robust OLS and IV estimates indicate a coefficient of relative prudence of around 2. We obtain similar results via partial identification methods using weak assumptions.
