Knowledge that Transforms

This paper uses an assignment model to understand the cross section of house prices within a metro area. Movers’ demand for housing is derived from a life-cycle problem with credit market frictions. Equilibrium house prices adjust to assign houses that differ by quality to movers who differ by age, income, and wealth. To quantify the model, we measure distributions of house prices, house qualities, and mover characteristics from micro-data on San Diego County during the 2000s boom. The main result is that cheaper credit for poor households was a major driver of prices, especially at the low end of the market.

This paper presents Gary Becker's approach to conducting creative, empirically fruitful economic research. It describes the traits and methodology that made him such a productive and influential scholar.

A corrective tax or subsidy is “well-targeted” if it primarily affects choices that are more distorted by market failures. Energy efficiency subsidies are designed to correct multiple distortions: externalities, credit constraints, “landlord-tenant” information asymmetries, imperfect information, and inattention. We show that three important energy efficiency subsidies are primarily taken up by consumers who are wealthier, own their own homes, and are more informed about and attentive to energy costs. This suggests that these subsidies are poorly targeted at the market failures they were designed to address. However, we show that “tagging” can lead to large efficiency gains.

This paper uses a unique and rich administrative data set to analyze the impact of the introduction of a new grading policy on graduations rates at Benedict College, a Historically Black College in Columbia, South Carolina. According to the new grading policy, grades for underclassmen are determined in part by performance on tests and in part by measures of “effort” such as attendance and class participation. This paper finds that while graduates graduate at a faster rate under the policy, there is no significant difference between graduation rates before and after the policy was implemented.

We provide evidence that unemployment insurance affects equilibrium conditions in the labor market, which creates significant “market externalities.” We provide a framework for identification of such equilibrium effects and implement it using the Regional Extension Benefit Program (REBP) in Austria which extended the duration of UI benefits for a large group of eligible workers in selected regions of Austria. We show that non-eligible workers in REBP regions have higher job finding rates, lower unemployment durations, and a lower risk of long-term unemployment. We discuss the implications of our results for optimal UI policy.

High rates of customer default on utility bills present a barrier to the expansion of electricity access in the developing world. Pre-paid electricity metering offers a technological solution to ensuring timely payment. Using an eleven-year panel of pre-paid electricity customers in Cape Town, South Africa, we describe patterns of purchase behavior across property values, our measure of socioeconomic status. Poorer households buy electricity more often, in smaller increments, and are most likely to buy on payday. These patterns suggest difficulties smoothing income, and reveal a preference for small, frequent purchases that is incompatible with a standard monthly electricity billing cycle.

This paper describes a growth model with the property that human capital accumulation can account for all observed growth. The model is shown to be consistent with evidence on individual productivities as measured by census earnings data. The central hypothesis is that we learn more when we interact with more productive people.

We pose good markets frictions on top of an otherwise standard two-country international real business cycle (IRBC) model. Shopping for goods takes effort, which prevents perfect matching between customers and producers. An increase in search effort implies increased measured productivity. Demand shocks increase expenditures and search effort simultaneously increasing output, consumption, productivity, and the trade deficit and appreciating the real exchange rate. Thus we solve the Backus-Smith puzzle and we show that the cross country correlation of consumption is higher than that of output. Standard IRBC models cannot account for these puzzles along with movements in TFP.

This paper studies the impact of an R&D cost shock on R&D investments, imported inputs, and their joint impact on firm performance. We introduce imported inputs into a model of R&D and endogenous productivity, and show that R&D and international sourcing are complementary activities. Exploiting the introduction of an R&D tax credit in Norway in 2002, we find that cheaper R&D stimulated not only R&D investments but also imports of intermediates, quantitatively consistent with the model. An implication of our work is that improved access to imported inputs promotes R&D investments and, ultimately, technological change.

Two key questions in thinking about the size and growth of the disability insurance program are to what extent it discourages work, and how valuable the insurance is to individuals and families. These questions motivate our paper. We begin by describing the earnings, disposable income, and consumption of awarded and rejected DI applicants, before and after the disability onset and the allowance decision. Next, we discuss how these descriptive results can be interpreted through the lens of alternative empirical approaches. Our analysis uses a Norwegian population panel data set with detailed information about every individual and household.
