The second edition of this acclaimed graduate text provides a unified treatment of two methods used in contemporary econometric research, cross section and data panel methods. By focusing on assumptions that can be given behavioral content, the book maintains an appropriate level of rigor while emphasizing intuitive thinking. The analysis covers both linear and nonlinear models, including models with dynamics and/or individual heterogeneity. In addition to general estimation frameworks (particular methods of moments and maximum likelihood), specific linear and nonlinear methods are covered in detail, including probit and logit models and their multivariate, Tobit models, models for count data, censored and missing data schemes, causal (or treatment) effects, and duration analysis. Econometric Analysis of Cross Section and Panel Data was the first graduate econometrics text to focus on microeconomic data structures, allowing assumptions to be separated into population and sampling assumptions. This second edition has been substantially updated and revised. Improvements include a broader class of models for missing data problems; more detailed treatment of cluster problems, an important topic for empirical researchers; expanded discussion of "generalized instrumental variables" (GIV) estimation; new coverage (based on the author's own recent research) of inverse probability weighting; a more complete framework for estimating treatment effects with panel data, and a firmly established link between econometric approaches to nonlinear panel data and the "generalized estimating equation" literature popular in statistics and other fields. New attention is given to explaining when particular econometric methods can be applied; the goal is not only to tell readers what does work, but why certain "obvious" procedures do not. The numerous included exercises, both theoretical and computer-based, allow the reader to extend methods covered in the text and discover new insights.

Econometric Analysis of Cross Section and Panel Data

This paper comprehensively examined the linkages between systems of High Performance Work Practices and firm performance. Results based on a national sample of nearly one thousand firms indicate that these practices have an economically and statistically significant impact on both intermediate outcomes (turnover and productivity) and short- and long-term measures of corporate financial performance. Support for the predictions that the impact of High Performance Work Practices is in part contingent on their interrelationships and links with competitive strategy was limited.

The Impact of Human Resource Management Practices on Turnover, Productivity, and Corporate Financial Performance

This study comprehensively evaluated the links between systems of High Performance Work Practices and firm performance. Results based on a national sample of nearly one thousand firms indicate that these practices have an economically and statistically significant impact on both intermediate employee outcomes (turnover and productivity) and short- and long-term measures of corporate financial performance. Support for predictions that the impact of High Performance Work Practices on firm performance is in part contingent on their interrelationships and links with competitive strategy was limited.

The Impact Of Human Resource Management Practices On Turnover, Productivity, And Corporate Financial Performance

This paper considers causal inference and sample selection bias in nonexperimental settings in which (i) few units in the nonexperimental comparison group are comparable to the treatment units, and (ii) selecting a subset of comparison units similar to the treatment units is difficult because units must be compared across a high-dimensional set of pre-treatment characteristics. We discuss the use of propensity score-matching methods, and implement them using data from the National Supported Work experiment. Following LaLonde (1986), we pair the experimental treated units with nonexperimental comparison units from the CPS and PSID, and compare the estimates of the treatment effect obtained using our methods to the benchmark results from the experiment. For both comparison groups, we show that the methods succeed in focusing attention on the small subset of the comparison units comparable to the treated units and, hence, in alleviating the bias due to systematic differences between the treated and compariso...

Equilibrium Unemployment Theory

What are the prospects for improving the lot of US workers in the 21st century? This introduction to the topic examines the most important US labor market trends of the late 20th and early 21st centuries, considers their causes and likely future trends; and then explores policies that might improve these outcomes. The most important broad labor market trends in recent decades have been: 1) Modest real wage growth; 2) Rising earnings inequality; and 3) Declining labor force participation, recently among both men and women, but especially among less-educated or African-American men and low-income youth over several decades. Key causes of these trends include labor demand and supply factors (such as automation, immigration, and limited college attainment); changing labor market institutions (such as declining unionism and stagnant federal wage/hours laws); rising alternative staffing arrangements, informal work and "fissuring"; and uneven labor market progress and policies affecting women, African-Americans and the young. After that review, we summarize what the papers in our volume tell us about the public policies that could help improve outcomes for US workers. The main message is that further deterioration in many US workers' lives in the 21st century likely requires public and employer policy changes to help to translate the forces at work into better outcomes for them.

Improving Employment and Earnings in 21st Century Labor Markets: An Introduction

This paper uses data from a nationwide sample of firms on employee wages and characteristics to reexamine the determinants of employee productivity and earnings. The data include several measures of job experience, training, and both worker and firm characteristics as well as subjective employer productivity ratings and earnings of workers. Given observations on the same individual at different points in time, we can consider both levels and changes in earnings and productivity, with various firm- and job-specific effects eliminated from the latter. The results show that: 1) Both previous experience and tenure in the current job have significant, positive effects on wages and productivity. Previous experience effects are found primarily on levels of wages and productivity while tenure affects occur for both current levels and changes. 2) Hours of training are positively related to productivity and wage growth but generally not to levels of either. 3) Among demographic characteristics, we find productivity growth and current productivity levels to be slightly higher for females while their wages are significantly lower. Other determinants of earnings and productivity ratings (e.g., such as various types of incentive pay and the fraction unionized) are considered here as well.

The Determinants of Employee Productivity and Earnings: Some New Evidence

We describe trends in wages and labor force participation for the “working class”—whom we define as workers with high school or less education—compared to those with college or more. We compare cyclical peaks over the entire period 1979–2019, with particular focus on the Great Recession (2007–2010) and recovery (2010–2019). We also present results by gender and race. We find real wage growth in the latter period for all workers, but not enough to change the long-term trends of growing inequality and stagnant wages for the less-educated; and we also find that labor force participation continued to decline for the less-educated, even during the recovery. Gaps between whites and blacks also grew, while Hispanics and Asians made more progress. We consider various explanations of these findings and show that the early effects of the 2020‒2021 pandemic recession hurt less-educated workers and those of color more than anyone else.

Labor Market Trends and Outcomes: What Has Changed since the Great Recession?

This paper presents evidence that young unemployed job seekers choose higher levels of search effort (as measured by numbers of methods used and time spent per method) and lower relative reservation wages than do comparable employed seekers. The unemployed also have higher probabilities of gaining new employment, which reflect higher probabilities of receiving offers and especially higher probabilities of accepting them; as well as slightly lower wages.These differences in outcomes between the two groups are at least partly explained by differences in their respective search choices.The evidence thus suggests that unemployed job seekers have higher costs of search (from foregone earnings) than do the employed, causing the former to seek new jobs more eagerly.

Employed and Unemployed Job Search: A Comparison of Choices and Outcomes among Youth

In this paper we use micro data from the Employment Opportunity Pilot Project (EOPP) surveys of firms in 1980 and 1982 to test for labor market rigidities and asymmetries in response to demand shifts. We analyze wage and employment adjustments to positive and negative shifts, as measured by sales growth between 1979 and 1981. The analysis is done for both entire sample of firms and for selected subsamples based on firm size, unionization, industry and skill mix. The results show that wage adjustments appear to be fairly rigid, compared with employment adjustments. They also appear to be quite asymmetric, with significant adjustments in response to positive shifts but little adjustment in response to negative shifts. These asymmetries are not more pronounced in large firms, manufacturing, heavily-waged or highly-skilled industries than in other firms or industries. In contrast, employment adjustments show no consistent pattern of asymmetry.
