Trade-Offs
How economists analyze real-world issues from overeating to organ transplants: “A wonderful introduction to economics for the layperson.” —Choice When economists wrestle with issues such as unemployment, inflation, or budget deficits, they do so by incorporating an impersonal, detached mode of reasoning. But economists also analyze issues that, to others, typically do not fall within the realm of economic reasoning, such as organ transplants, cigarette addiction, overeating, and product safety. Trade-Offs is an introduction to the economic approach to analyzing these controversial public policy issues. Harold Winter provides readers with the analytical tools needed to identify and unde...
Drinking and Academic Performance in High School
We investigate the extent to which negative alcohol use coefficients in GPA regressions reflect unobserved heterogeneity rather than direct effects of drinking, using 2001 and 2003 Youth Risk Behavior Survey data on high school students. Results illustrate that omitted factors are quite important. Drinking coefficient magnitudes fall substantially in regressions that control for risk and time preference, mental health, self-esteem, and consumption of other substances. Moreover, the impact of binge drinking is negligible for students who are less risk averse, heavily discount the future, or use other drugs. However, effects that remain significant after accounting for unobserved heterogeneity and are relatively large for risk averse, future oriented and drug free students suggest that binge drinking might slightly worsen academic performance. Consistent with this, the relationship between grades and drinking without binging is small and insignificant on the extensive margin and positive on the intensive margin
21st Century Economics: A Reference Handbook
Interest in economics is at an all-time high. Among the challenges facing the nation is an economy with rapidly rising unemployment, failures of major businesses and industries, and continued dependence on oil with its wildly fluctuating price. Americans are debating the proper role of the government in company bailouts, the effectiveness of tax cuts versus increased government spending to stimulate the economy, and potential effects of deflation. Economists have dealt with such questions for generations, but they have taken on new meaning and significance. Tackling these questions and encompassing analysis of traditional economic theory and topics as well as those that economists have only ...

Paying the Tab
What drug provides Americans with the greatest pleasure and the greatest pain? The answer, hands down, is alcohol. The pain comes not only from drunk driving and lost lives but also addiction, family strife, crime, violence, poor health, and squandered human potential. Young and old, drinkers and abstainers alike, all are affected. Every American is paying for alcohol abuse. Paying the Tab, the first comprehensive analysis of this complex policy issue, calls for broadening our approach to curbing destructive drinking. Over the last few decades, efforts to reduce the societal costs--curbing youth drinking and cracking down on drunk driving--have been somewhat effective, but woefully incomplet...
Practical Volatility and Correlation Modeling for Financial Market Risk Management
"What do academics have to offer market risk management practitioners in financial institutions? Current industry practice largely follows one of two extremely restrictive approaches: historical simulation or RiskMetrics. In contrast, we favor flexible methods based on recent developments in financial econometrics, which are likely to produce more accurate assessments of market risk. Clearly, the demands of real-world risk management in financial institutions--in particular, real-time risk tracking in very high-dimensional situations--impose strict limits on model complexity. Hence we stress parsimonious models that are easily estimated, and we discuss a variety of practical approaches for high-dimensional covariance matrix modeling, along with what we see as some of the pitfalls and problems in current practice. In so doing we hope to encourage further dialog between the academic and practitioner communities, hopefully stimulating the development of improved market risk management technologies that draw on the best of both worlds"--National Bureau of Economic Research web site.
Does Food Aid Harm the Poor?
"This paper uses household-level data from Ethiopia to investigate the impact of food aid on the poor. We find that food aid in Ethiopia is "pro-poor." Our results indicate that (i) net buyers of wheat are poorer than net sellers of wheat, (ii) there are more buyers of wheat than sellers of wheat at all levels of income, (iii) the proportion of net sellers is increasing in living standards and (iv) net benefit ratios are higher for poorer households indicating that poorer households benefit proportionately more from a drop in the price of wheat. In light of this evidence, it appears that households at all levels of income benefit from food aid and that - somewhat surprisingly - the benefits go disproportionately to the poorest households"--NBER website
