We present a growth model whose novelty is to explicitly account for the direct, preference-related factors that reinforce the delay in the timing of childbearing. Given the strength of these factors, the model generates the empirically observed dynamics in completed cohort fertility. Furthermore, the quantitative analysis of our results verifies that our model provides a good fit for actual data of the rebound of the completed cohort fertility rates in Nordic countries. The fact that these countries are widely considered as the most progressive ones, in terms of their cultural norms and in terms of their family-oriented policies, offers credence to the hypothesis that our model advances. More generally, our framework provides a platform for research that can uncover empirically relevant, but yet unexplored, mechanisms in the joint analysis of demographic change and economic growth.

Previous research has shown that societies that historically focused on agricultural production demonstrate higher levels of long-term orientation. This suggests that the deep-rooted cultural origins of time preference may have a scarring impact on modern obesity rates through intergenerational transmission. We hypothesize that a historically long-term oriented culture could result in the behavioural choices of better diet and more exercise today, via the reinforced ability of individuals to delay gratification. Using a sample of 132 countries, we employ regression analysis to first estimate the historical determinants of time preference, and then examine the impact of long-term orientation on obesity. Controlling for other factors, we find that, on average, historically long-term oriented countries exhibit significantly lower obesity rates today. Results are robust to different methodological approaches and sensitivity analyses. Policies targeting obesity should consider those deep-rooted behavioural factors that can determine the differential response of individuals to policy instruments. • Can the cultural origins of time preference have an impact on modern obesity rates? • We test this hypothesis using a sample of 132 countries. • We estimate the determinants of time preference and the impact of long-term orientation on obesity. • Historically long-term oriented countries exhibit lower obesity rates today.
