We present a structural model and employ discrete time survival analysis to examine the impact of weather conditions on firms' exit decisions within the New England ski industry. Our results suggest that weather conditions can have significant direct and indirect effects on the closure of ski areas. The results also indicate that larger ski areas are more likely to engage in investment activities...
In this survey, we give a friendly introduction from a graph theory perspective to the q-state Potts model. The Potts model is an important statistical mechanics tool for analyzing complex systems in which nearest neighbor interactions determine the aggregate behavior of the system. We present the surprising equivalence of the Potts model partition function and one of the most renowned graph invariants,...
