Knowledge that Transforms

This paper examines whether giving large cash transfers to financially distressed people causes them to avoid bankruptcy. A comparison of Florida Lottery winners who randomly received $50, 000 to $150, 000 to small winners indicates that such transfers only postpone bankruptcy rather than prevent it, a result inconsistent with the negative shock model of bankruptcy. Furthermore, the large winners who subsequently filed for bankruptcy had similar net assets and unsecured debt as small winners. Thus, our findings suggest that skepticism regarding the long-term impact of cash transfers may be warranted.

This paper shows that, consistent with a signaling-by-consuming model à la Veblen, income elasticities can be predicted from the visibility of consumer expenditures. We outline a stylized conspicuous consumption model where income elasticity is endogenously predicted to be higher if a good is visible and lower if it is not. We then develop a survey-based measure of expenditure visibility, ranking different expenditures by how noticeable they are to others. Finally, we show that our visibility measure predicts up to one-third of the observed variation in elasticities across consumption categories in U.S. data.

This paper investigates the sources of the substantial decrease in output growth volatility in the mid-1980s by identifying which of the structural parameters in a representative New Keynesian and structural VAR models changed. Overturning conventional wisdom, we show that the Great Moderation was due not only to changes in shock volatilities but also to changes in monetary policy parameters, as well as in the private sector's parameters. The Great Moderation was previously attributed to good luck because the alternative sources of instabilities appear to have offsetting effects on output volatility and therefore were impossible to detect using existing techniques.

Using California ballot proposition returns and exogenous shifts to labor demand, we provide the first large-scale causal evidence of the impact of economic conditions on policy preferences. Consistent with economic theory, we find that positive economic shocks decrease support for redistributive policies. More notably, we find evidence of a need for cognitive consistency in voting behavior as economic shocks have a smaller significant impact on voting on noneconomic ballot issues. While we also demonstrate that positive shocks decrease turnout, we present evidence that our results reflect changes in the electorate's preferences and not simply to its composition.

I use a long panel with broad grade coverage to establish whether charter schools affect cognitive and noncognitive skill formation. Schools that begin as charters generate large improvements in discipline and attendance but not test scores, with the exception of math in middle schools. This suggests improvements in noncognitive but not cognitive skills, although these improvements do not persist if students return to regular public schools. Charters that convert from regular public schools have little impact on either skill type. These results are robust to potential biases from selection off of precharter trends, attrition, and persistence.

This paper uses Behavioral Risk Factor Surveillance System data to study life satisfaction and mental health across the geography of the United States. The analysis draws on a sample of 1.3 million citizens. Initially we control for people's personal characteristics (though not income). There is no correlation between states' regression-adjusted well-being and their GDP per capita. States like Louisiana, plus Washington, D.C., have high psychological well-being levels; California and West Virginia have low well-being. When we control for incomes, satisfaction with life is lower in richer states, just as compensating-differentials theory would predict. Nevertheless, some puzzles remain.

Current research on antidumping suggests a number of channels through which antidumping affects the volume of world trade. This paper uses a structural approach to the gravity model framework to evaluate these hypotheses using data on trade volume over the period 1948 to 2001. We conclude that the volume and welfare effects have been negative but quite modest.

Are price and consumption independent in flat-rate price service contexts? A field experiment at an all-you-can-eat pizza restaurant shows that a 50% discount on the price of the meal led customers to consume 27.9% less pizza (2.95 versus 4.09 pieces). A second analysis indicated that individual taste ratings of this pizza tended to be inversely related to how much is consumed. One possible interpretation of these two findings is that individuals in a flat-rate (or fixed-price) context may consume the amount that enables them to get their money's worth rather than consuming until their marginal utility of consumption is 0.

We explore the link between short-run cycles and long-run growth by examining the cyclicality of R&D. Existing theories propose that R&D is concentrated when output is low, but aggregate data repeatedly show that R&D appears procyclical. We estimate the relationship between R&D and output using an annual panel of twenty U.S. manufacturing industries from 1958 to 1998. The results indicate that R&D is in fact procyclical, but, interestingly, estimates using demand-shift instruments suggest that it responds asymmetrically to demand shocks. We propose that liquidity constraint is an important cause for the observed procyclicality of R&D.

Defined contribution pensions in many postsecondary institutions are funded by a combination of an employer premium and a mandatory employee premium. Individuals can also contribute to a supplemental savings account. Holding constant total compensation, standard reasoning suggests that supplemental savings should depend negatively on the sum of the employer and employee pension contributions. Contrarily, we find that the supplementary savings of professors are significantly more sensitive to employee contributions than to employer contributions. This asymmetry is consistent with different marginal propensities to save out of the salary and pension components of compensation. Nevertheless, impacts on lifetime utility are relatively modest.
