Incorporating Local Public Health Dynamics into The Rosen/Roback Spatial Equilibrium Model

Environmental and Urban Economics

Imagine if there is an infectious disease that spreads within cities but not across cities. Throughout the COVID crisis, the city specific infection rate has varied across cities at each point in time. In a city facing a rising infection rate, people can adapt by either engaging in costly self protection (self isolating) or through public health interventions such as vaccinating the local population. In this case, public health substitutes for private health protection investments.

Resources are all around us. But rarely do we think of water as a resource especially when considering wastewater. Yet for over 50 years, Veolia , a utility company has been converting wastewater into drinking water in Windhoek, Namibia. A tall order it would seem. However, come to think of it, water constitutes over 90% of wastewater. If that’s the case, why can’t we go the extra mile to reclaim it? WASTEWATER TREATMENT PLANTS.
