When data are censored, ordinary least squares regression can provide biased coefficient estimates. Maximum likelihood approaches to this problem are valid only if the error distribution is correctly specified, which can be problematic in practice. We review several semiparametric estimators for...

Most workers have one employment contract that is explicit and another one that is implicit. The explicit employment contract specifies working hours, compensation, and job tasks. The implicit contract involves expectations about the extent to which the employment relationship is likely to...

The inequality of earnings and of family incomes in the United States has increased since the late 1970s. The large rise in earnings inequality between the 1970s and the 1990s could reflect either a rise in disparity of permanent incomes, a rise in earnings instability, or some portion of both....

One explanation that has been proposed for rising inequality is that technical change allows highly talented individuals, or "superstars" to manage or perform on a larger scale, applying their talent to greater pools of resources and reaching larger numbers of people, thus becoming more...

The top 1 percent income share has more than doubled in the United States over the last 30 years, drawing much public attention in recent years. While other English-speaking countries have also experienced sharp increases in the top 1 percent income share, many high-income countries such as...

Over the past few decades of economic reform, China's labor markets have been transformed to an increasingly market-driven system. China has two segregated economies: the rural and urban. Understanding the shifting nature of this divide is probably the key to understanding the most important...

Are state and local government workers overcompensated? In this paper, we step back from the highly charged rhetoric and address this question with the two primary data sources for looking at compensation of state and local government workers: the Current Population Survey conducted by the...

This paper seeks to review how globalization might explain the recent trends in real and relative wages in the United States. We begin with an overview of what is new during the last 10-15 years in globalization, productivity, and patterns of U.S. earnings. To preview our results, we then work...

In recent decades, cheap labor has played a central role in the Chinese model, which has relied on expanded participation in world trade as a main driver of growth. At the beginning of China's economic reforms in 1978, the annual wage of a Chinese urban worker was only $1,004 in U.S. dollars....

Left- and right-handed individuals have different neurological wiring, particularly with regard to language processing. Multiple datasets from the United States and the United Kingdom show that lefties exhibit significant human capital deficits relative to righties. Lefties score 0.1 standard...
