- Description:
- Minimal mathematical models are used to understand complex phenomena in the physical, biological, and social sciences. This modeling philosophy never claims, nor even attempts, to fully capture the mechanisms underlying the phenomena, and instead offers insights and predictions not otherwise possible. Here, we build and explore minimal dynamical systems models...

- This dissertation investigates how public disclosure of quality information affects the behavior of firms. The first chapter uses a quality disclosure policy, the Nursing Home Quality Initiative (NHQI), to examine how quality "report cards" affect firms' choices of multidimensional product quality. I show that after the introduction of NHQI: (1)...

- Subsolidus phase relationships within the ZnO-In<sub>2</sub>O<sub>3</sub>-SnO<sub>2</sub> system at 1275 <sup>o</sup>C were established by conventional solid state reaction methods. No new compounds or structures were observed within the ternary diagram. Equilibrium in the ZnO-corner, between the homologous compounds and the spinel phase, was found difficult to achieve. This problem was overcome...
