Endogenous Growth and Demographic Transition in a model of Cultural Transmission
نویسنده
چکیده
Demographic transition theory is developed highlighting cultural transmission pattern as key driver. Individuals maximize cultural fitness, i.e. rate of own cultural type absorbtion by future generations. With low population density, one’s culture can be picked up only by own children, thus cultural fitness equals genetic fitness, individuals allocate all energy surplus to reproduction, and Malthusian regime occurs. With rising population density, cultural transmission between non-relatives accelerates; knowledge production by an individual makes her culture more attractive. Individuals reallocate some of energy surplus from reproduction to knowledge production, causing technological growth. The model fits observed demographic transition patterns.

متن کاملInvestigating the Relationship between Money Growth and Inflation in Turkey: A Nonlinear Causality Approach
Theories on the relationship between money and inflation had largely been shaped around the positive relationship and money causality for inflation before the Post-Keynesians. Since the 1980s, this idea emerged that there might be no correlation between money growth and inflation. In the case of existence, the causality is reversed, so money is endogenous somehow. However, practically there is ...
