Beginning in 1997, the price of concert tickets took off and ticket sales declined. From 1996 to 2003, for example, the average concert price increased by 82%, while the CPI increased by 17%. Explanations for price growth include (1) the possible crowding out of the secondary ticket market, (2) rising superstar effects, (3) Baumols and Bowen's disease, (4) increased concentraion of promoters, and (5) the erosion of complementarities between concerts and album sales because of file sharing and CD copying. The article tentatively concludes that the decline in complementarities is the main cause of the recent surge in concert prices.

This article examines the impact of a workplace education program at two companies (one in the manufacturing sector, the other in the service sector). We examine a broad range of outcome variables, including earnings, turnover, performance awards, job attendance, and subjective performance measures. We estimate a small, positive impact of the program on earnings at the manufacturing company but an insignificant impact at the service company. Trainees were equally likely to exit the company as nontrainees. We also find that the training had a positive association with the incidence of job bids, upgrades, performance awards, and job attendance.

This article examines the properties and prevalence of measurement error in longitudinal earnings data. The analysis compares matched Current Population Survey data to administrative Social Security payroll tax records. In contrast to typically assumed properties of measurement error, the results indicate that errors are serially correlated over two years and negatively correlated with true earnings (i.e., mean reverting). In a cross section, the ratio of the variance of the signal to the total variance is 0.82 for men and 0.92 for women. These ratios fall to 0.65 and 0.81 when the data are specified in first differences. Longitudinal earnings data may be more reliable than previously believed.

In most cities, the taxi industry is highly regulated and has restricted entry. Ride sharing services, such as Uber and Lyft, which use mobile internet technology to connect passengers and drivers, have begun to compete with traditional taxis. This paper examines the efficiency of ride sharing services vis-a-vis taxis. In most cities with data available, UberX drivers spend a significantly higher fraction of their time, and drive a substantially higher share of miles, with a passenger in their car than do taxi drivers. Reasons for this efficiency advantage are explored.

This paper uses a new survey to contrast the wages of genetically identical twins with different schooling levels. Multiple measurements of schooling levels were also collected to assess the effect of reporting error on the estimated economic returns to schooling. The data indicate that omitted ability variables do not bias the estimated return to schooling upward but that measurement error does bias it downward. Adjustment for measurement error indicates that an additional year of schooling increases wages by 12 to 16 percent, a higher estimate of the economic returns to schooling than has been previously found.
