Knowledge that Transforms

Policymakers often assume that targeting observably poor households suffices in reaching nutritionally deprived individuals. We question that assumption. Our comprehensive assessment for sub-Saharan Africa reveals that undernourished women and children are spread widely across the household wealth and consumption distributions. Roughly three-quarters of underweight women and undernourished children are not found in the poorest 20% of households, and around half are not found in the poorest 40%. Countries with higher undernutrition tend to have higher shares of undernourished individuals in nonpoor households. Intrahousehold inequality accounts in part for our results, but other factors appear to be important, including common health risks.

This paper examines the long-term determinants of intimate partner violence (IPV) by analyzing its relationship with traditional family structures: stem families in which one child stays in the parental household and nuclear families in which all children leave the household upon marriage. My hypothesis is that coresidence with a mother-in-law increases a wife's contribution to nondomestic work, which may decrease the level of violence. I find that areas where stem families were socially predominant in the past currently have a lower IPV rate, and use differences in inheritance laws in medieval times as an instrument for the different family types.

Transfer programs have been shown to reduce intimate partner violence (IPV), but little evidence exists on how activities linked to transfers affect IPV or what happens when programs end. We assess postprogram impacts on IPV of randomly assigning women in Bangladesh to receive cash or food, with or without nutrition behavior change communication (BCC). Six to ten months postprogram, IPV did not differ between women receiving transfers and a control group; however, women receiving transfers with BCC experienced 26% less physical violence. Evidence on mechanisms suggests sustained effects of BCC on women's “threat points,” men's social costs of violence, and household well-being.

Whereas attitudes toward risk play an important role in many decisions over the life course, factors that affect those attitudes are not fully understood. Using longitudinal survey data collected in Mexico before and during the Mexican war on drugs, we investigate how risk attitudes change with variation in insecurity and uncertainty brought on by unprecedented changes in local-area violent crime. Exploiting the fact that the timing, virulence, and spatial distribution of changes in violent crime were unanticipated, we establish there is a rise in risk aversion spread across the entire local population as local-area violent crime increases.

This paper investigates whether attitudes are affected by politico-economic regimes. We exploit the efforts of state socialist regimes to promote women's economic inclusion. Using the German partition after World War II, we show that women from East-Germany are more likely to place importance on career success compared to women from West-Germany. Further, the population at large in East Germany is less likely to hold traditional gender role attitudes. Examining possible mechanisms, we find that the change in attitudes under the East German regime was larger in areas where the growth in female employment was larger. A comparison of Eastern versus Western Europe confirms these results.

We estimate the impact of Kenya's postelection crisis on individual risk preferences. The crisis interrupted a longitudinal survey of more than five thousand Kenyan youth, creating plausibly exogenous variation in exposure to civil conflict prior to the survey. Our results indicate that the postelection crisis sharply increased individual risk aversion. Immediately after the crisis, the fraction of subjects displaying extreme risk aversion increased by more than 80%. Findings remain robust when we use an IV estimation strategy that exploits random assignment of respondents to waves of surveying. The crisis also affected trust, social capital, and beliefs about the economy.

We attribute the recent quadrupling of heroin death rates to the August 2010 reformulation of an oft-abused prescription opioid, OxyContin. The new abuse-deterrent formulation led many consumers to substitute an inexpensive alternative, heroin. Using structural break techniques and variation in substitution risk, we find that opioid consumption stops rising in August 2010, heroin deaths begin climbing the following month, and growth in heroin deaths was greater in areas with greater prereformulation access to heroin and opioids. The reformulation did not generate a reduction in combined heroin and opioid mortality: each prevented opioid death was replaced with a heroin death.

We study how individuals repay their debt using linked data on multiple credit cards. Repayments are not allocated to the higher interest rate card, which would minimize the cost of borrowing. Moreover, the degree of misallocation is invariant to the economic stakes, which is inconsistent with optimization frictions. Instead, we show that repayments are consistent with a balance-matching heuristic under which the share of repayments on each card is matched to the share of balances on each card. Balance matching captures more than half of the predictable variation in repayments and is highly persistent within individuals over time. (JEL D14, D15, D91, G41)

Media censorship is a hallmark of authoritarian regimes. We conduct a field experiment in China to measure the effects of providing citizens with access to an uncensored internet. We track subjects’ media consumption, beliefs regarding the media, economic beliefs, political attitudes, and behaviors over 18 months. We find four main results: (i) free access alone does not induce subjects to acquire politically sensitive information; (ii) temporary encouragement leads to a persistent increase in acquisition, indicating that demand is not permanently low; (iii) acquisition brings broad, substantial, and persistent changes to knowledge, beliefs, attitudes, and intended behaviors; and (iv) social transmission of information is statistically significant but small in magnitude. We calibrate a simple model to show that the combination of low demand for uncensored information and the moderate social transmission means China’s censorship apparatus may remain robust to a large number of citizens receiving access to an uncensored internet.
