Exploring theoretical frameworks for the analysis of fertility fluctuations

subject

description

The Easterlin theory, popular during the 1970s, explained population fluctuations in terms of maximization of choice, based on the evaluation of previously acquired information. Fluctuations in procreational patterns were seen as responses to conflict between 2 consecutive generations in which the propensity to procreate is inversely related to cohort size. However, the number of demographic trends not directly explainable by the hypothesis imply that either the model must be extended over a longer time frame or that there has been a drastic change of regime, i.e., a basic change in popular attitudes which determine decision making behavior. 4 strategic principles underlie reproductive decisions: primary adaptation, economic utility, norm internalization, and identity reinforcement. The decision-making process is determined by the relative importance of these 4 principles. Primary adaptation implies inertia, i.e., nondecision. Economic utility implies the use of rational choice to maximize economic gain. Norm internalization implies conforming to the behavior of one's sociocultural peers as if it were one's own choice. Identity reinforcement implies that one decides to reproduce because procreation is a way of extending one's identity forward in time. The 2 active decision-making attitudes, economic rationality and identity reinforcement, are strategically both antagonistic and complementary. This polarity of behavior lends itself to analysis in terms of the predator-prey model, in which population is seen as the predator and resources as the prey. However, in applying the model, one must keep in mind that the real demographic picture is not static and that it is subject to deformation by external forces.
