This paper discusses and illustrates identification problems in personality psychology. The measures used by psychologists to infer traits are based on behaviors, broadly defined. These behaviors are produced from multiple traits interacting with incentives in situations. In general, measures...

Research on the causes of delinquency has a long research history, often with an undue focus on how cognitive ability serves as the main predictor of delinquent activity. The current review examines interventions that focus on psychological factors other than cognitive ability, and discusses how...

We construct a structural model of entry into self-employment to evaluate the impact of policies supporting entrepreneurship. Previous work has recognized that workers may opt for self-employment due to the non-pecuniary benefits of running a business and not necessarily because they are good at...

We disaggregate the self-employed into incorporated and unincorporated to distinguish between "entrepreneurs" and other business owners. We show that the incorporated self-employed and their businesses engage in activities that demand comparatively strong nonroutine cognitive abilities, while...

This paper describes measurement of a self-employment rate and the important role the agricultural sector plays in any analysis of the determinants of self-employment. The determinants of the self-employment rate are modeled using a panel of 23 countries for the period 1966-1996. A similar...

This paper tests a central implication of the theory of equalizing differences, that workers sort into jobs with different attributes based on their preferences for those attributes. We present evidence from four new time-use data sets for the United States and France on whether workers who are...

Nearly a quarter of Mexico's workforce is self employed. But in the U.S. rates of self employment among Mexican Americans are only 6 percent, about half the rate among non-Latino whites. Using data from the Mexican and U.S. population census, we show that neither industrial composition nor...

This paper examines the pattern of self-employment in Australia and the United States. We particularly focus on the movement of young people in and out of self-employment using comparable longitudinal data from the two countries. We find that the forces that influence whether a person becomes...

n this paper I examine changes in self-employment that have occurred since the early 1980s in the United States. It is a companion paper to a recent equivalent paper that related to the UK. Data on random samples of approximately twenty million US workers are examined taken from the Basic...

This paper examines how the level and dispersion of self-reported happiness has evolved over the period 1972-2006. While there has been no increase in aggregate happiness, inequality in happiness has fallen substantially since the 1970s. There have been large changes in the level of happiness...
