How Destructive Is Creative Destruction? The Costs of Worker Displacement We analyze short and long-term effects of worker displacement. Our focus is on prime-age male workers displaced from Norwegian manufacturing plants. We find that displacement increases the probability of exiting the labor force by about 5 percentage points. This indicates that studies using data that do not incorporate wo...

The Moving to Opportunity (MTO) experiment offered randomly selected families housing vouchers to move from high-poverty housing projects to lower-poverty neighborhoods. We analyze MTO's impacts on children's long-term outcomes using tax data. We find that moving to a lower-poverty neighborhood when young (before age 13) increases college attendance and earnings and reduces single parenthood ra...

We investigate hysteretic behavior in two dynamic models for solid-solid phase transitions. An elastic bar with a nonconvex double-well elastic energy density is subjected to time-dependent displacement boundary conditions. Both models include inertia and a viscous stress term that provides energy dissipation. The first model involves a strain-gradient term that models interfacial energy. In th...

Near infrared tunable diode laser (NE-TDL) spectroscopy is used to quantify HF gas produced during fire suppressant testing of halon alternatives. Results of comparisons with other techniques for measuring HF gas concentrations are discussed. Measurements of HF gas produced in laboratory and real-scale fire suppression testing are presented. The necessity for time-resolved measurements during t...
