This paper combines information from two sources of U.S. private payroll employment to increase the accuracy of real-time measurement of the labor market. The sources are the Current Employment Statistics (CES) from BLS and microdata from the payroll processing firm ADP. We briefly describe the...

Since 1979, the Bureau of Labor Statistics (BLS) has nearly quadrupled the size of the sample used to estimate monthly employment changes. Although first-reported employment estimates are still noisy, the magnitude of sampling variability has declined in proportion to the increase in the sample...

This essay sets out a framework for evaluating empirical work in terms of the ability of the data to provide adequate parameter estimates and hypothesis tests about the true underlying structure. Problems of aggregation, representativeness and structural change are discussed in detail. These...

When the US Bureau of Labor Statistics releases new numbers, in theory it should make no difference whether the press release emphasizes the most recent 1-month number, which is what it always does, or the 12-month number, as many other countries' statistical agencies do. This paper offers the...

This paper documents that rotation group bias -- the tendency for labor force statistics to vary systematically by month in sample in labor force surveys -- in the Current Population Survey (CPS) has worsened considerably over time. The estimated unemployment rate for earlier rotation groups has...

In a famous paper, Kenneth Sokoloff argued that the labor input of entrepreneurs was generally not included in the count of workers in manufacturing establishments in the early censuses of manufacturing. According to Sokoloff, this biased downward econometric estimates of economies of scale if...

Good data on the size and composition of the independent contractor workforce are elusive, with household survey and administrative tax data often disagreeing on levels and trends. We carried out a series of focus groups to learn how self-employed independent contractors speak about their work....

"A long-standing question in social science is to what extent differences in management cause differences in firm performance. To investigate this we ran a management field experiment on large Indian textile firms. We provided free consulting on modern management practices to a randomly chosen...

"Empirical studies of the relationship between school inputs and test scores typically do not account for the fact that households will respond to changes in school inputs. We present a dynamic household optimization model relating test scores to school and household inputs, and test its...

Since the late 1980s the global intellectual property rights (IPR) system has been strengthening dramatically as much of the developing world introduces patent protection for new drug products. This may lead to more research on drugs to address developing country needs. As there are identifiable...
