Using Portugal's extensive matched employer-employee data set, this paper documents an unusual feature of the Portuguese economy. For decades, the entire Portuguese firm size distribution has been shifting to the left. We argue in this paper that Portugal's shrinking firms are linked to the...

This study examines the extent and influence of occupational licensing in the U.S. using a specially designed national labor force survey. Specifically, we provide new ways of measuring occupational licensing and consider what types of regulatory requirements and what level of government...

Promoting minimum age of employment regulation has been a centerpiece in child labor policy for the last 15 years. If enforced, minimum age regulation would change the age profile of paid child employment. Using micro-data from 59 mostly low-income countries, we observe that age can explain less...

The effect of shift structure on worker performance and productivity is an issue of increasing interest to firms and regulatory bodies. Using approximately 742,000 emergency medical incidents attended by 2,400 paramedics in the state of Mississippi, we evaluate the extent to which paramedics'...

A principal reason that losses from catastrophic risks have been increasing over time is that more individuals and firms are locating in harm's way while not taking appropriate protective measures. Several behavioural biases lead decision-makers not to invest in adaptation measures until after...

We model tipping as a game-theoretic phenomenon and investigate the connection between supermodular games, tipping of equilibria and cascading, and apply the results to issues that arise in the context of homeland security and computer security. We show that tipping and cascading can occur in...

Individuals' risk preferences are estimated and employed in a variety of settings, notably including choices in financial, labor, and product markets. Recent work, especially in financial economics, provides estimates of individuals' coefficients of relative risk aversion (CRRA's) in excess of...

This paper demonstrates gender differences in risk aversion and ambiguity aversion. It also contributes to a growing literature relating economic preference parameters to psychological measures by asking whether variations in preference parameters among persons, and in particular across genders,...

This paper argues that, since activities that provide political information are complementary with leisure, increased labor market activity should lower turnout, but should do so least in prominent elections where information is ubiquitous. Using official county-level voting data and a variety...

The crisis of 2007-09 has been characterized by a sudden freeze in the market for short-term, secured borrowing. We present a model that can explain a sudden collapse in the amount that can be borrowed against finitely-lived assets with little credit risk. The borrowing in this model takes the...
