The research area of the new economics of personnel has a short but important and insightful history. Theory ahead of measurement asks for testing newly developed human resource concepts. These tests often need detailed firm-specific data. Repetition and comparison of results is key in finding...

This paper develops a theoretical model of a worker?s decision problem under uncertainty about the optimal separation time, when holding a representative outside offer but facing fixed costs of quitting. Implications of the model?s closed form solution are consistent with the quit behavior of...

This paper investigates differences in worker turnover characteristics between periods of workforce expansion and contraction in a firm. We derive a Cox proportional hazard model from a simple model of job separation based on the expected surpluses from the firm and its workers. We account for...

We study the self-employed decision and its relation to human and social capital. Human capital is necessary to acquire skills. Social capital dampens the effects of uncertainty about future income. Our data set consists of 1339 respondents from the same age group, who were interviewed three...

Optimal layoff rules in closed form are derived for all workers in a firm that downsizes under uncertainty and faces heterogeneous firing costs. The theoretical model predicts that the firm displaces workers with low firing costs, low expected future productivity growth, and low layoff option...

This paper measures the value of functional capacity improvement from electronic pain treatment among a sample of Dutch workers with peripheral nerve injuries. Randomized clinical trial data and individual medical records from injured workers are compared with administrative data of healthy...

We construct a general dynamic structural model of two-sided learning between a firm and its workers. We estimate an empirical version of the model using personnel data from Fokker Aircraft that cover the path of layoffs and quits through its bankruptcy. We find that the firm learns about its...

A structural model of entry and fiscal policy is presented. It shows that taxation of variable production costs can increase product prices, lower competition, and reduce the availability of new products in small markets. The model?s test is based on a unique nationwide fiscal experiment. We...

This paper analyzes whether part-time employment is beneficial for firm productivity in the service sector. Using a unique dataset on the Dutch pharmacy sector that includes the work hours of all employees and a hard physical measure of firm productivity, we estimate a production function...

Several studies document the fact that low-educated workers participate less often in further training than high-educated workers. The economic literature suggests that there is no significant difference in employer willingness to train low-educated workers, which leaves the question of why the...
