...Kenneth W. Wachter; Ronald D. Lee Abstract Lee’s (1974) formal demographic feedback models summarize the implications for births and age-structure of neo-Malthusian theories of baby booms such as those of Easterlin. For some parameter values, such models imply sustained cycles, so-called “limit...

... earnings. I Similarly, poor health may trigger the re- ceipt of means-tested government transfer income. The net result is that health enters into the model in two ways, producing possible two-way feedbacks between health and income. Good health is an outcome that people desire, and higher income enables...

If classic density dependence appears of little relevance to contemporary popula- tion dynamics, there is still scope for nonlinear models in which feedback operates in other ways.

Pollution levels, for example, may influence population growth by elevating mortality or by triggering growth-con- trol regulations or, more likely, by mediating rates of migra- tion. Pollution levels (I) may also trigger environmental regulatory efforts (T...

In geography, spatially explicit agent-based models have been developed to describe land use change in a variety of settings (e.g., Brown et al. 2005; Evans and Kelley 2004), although they do not elaborate key demographic compo- nents such as feedbacks...
