We posit a spatially explicit, county-level model of the hog production sector and estimate how numerous firm-specific, locality-specific, and spatial agglomeration factors affect the location, movement, and intensity of hog production within 15 key hog production states. Spatial agglomeration,...

This paper establishes a coupled human-ecological model where slow-varying migration is interacting with fast-varying nutrient dynamics in lake ecology. The nonlinearity and fast-slow dynamics built in the model can generate regime shifts (that is, shifts between different equilibrium states)...

We develop a coupled model of regional migration and lake ecology to study the influence of ecological-economic interactions and relative time scales on transient and asymptotic dynamics. Cross-scale interactions fundamentally change system dynamics by eliminating steady states that are present...
