DOWNLOAD EBOOKNew insights - from new data - on the relationship between population growth, factor accumulation, and productivity.In research on how population growth affects economic performance, some researchers stress that population growth reduces the natural resources and capital (physical and human) per worker while other researchers stress how greater population size and density affect productivity. Despite these differing theoretical predictions, the empirical literature has focused mainly on the relationship between population growth and output per person (or crude proxies for factor accumulation). It has not decomposed the effect of population through factor accumulation and the effect through productivity.Pritchett uses newly created cross-country, time-series data on physical capital stocks and the educational stock of the labor force to establish six findings:There is no correlation between the growth of capital per worker and population growth.The common practice of using investment rates as a proxy for capital stock growth rates is completely unjustified, as the two are uncorrelated across countries.There is either no correlation, or a weak positive correlation, between the growth of years of schooling per worker and the population growth rate.Enrollment rates are even worse as a crude proxy for the expansion of the educational capital stock, as the two are negatively correlated.There is no correlation, or a weak negative correlation, between measures of total factor productivity growth and population growth.Nearly all of the weak correlation between the growth of output per person and population growth is the result of shifts in participation in the labor force, not of changes in output per worker.This paper is a product of the Poverty and Human Resources Division, Policy Research Department.

DOWNLOAD EBOOKThis paper analyzes the conditions under which, within a two-sector endogenous growth model with human and physical capital accumulation but without R&D-driven disembodied technological progress, we can observe an ambiguous effect of population growth on economic growth, as empirical evidence suggests. We present, in turn, three models. In each of them skill acquisition represents the engine of long-run economic growth. Population growth exerts ambiguous effects on economic growth only when human and physical capital investments are complementary for each other. This result is explained in terms of the interplay between the “dilution” and “accumulation” effects. In accordance with the growth literature exhibiting endogenous human capital accumulation and R&D activity, we also find that income growth can be positive even with stable population, that both the growth rate and the level of per-capita income are independent of population size and, finally, that the level of per-capita income is proportional to the level of per-capita human capital. We conclude that, even without explicitly assuming purposeful investment in research activity by firms, it is possible to reach the same results.

DOWNLOAD EBOOKThe model developed here postulates that learning through experience plays a critical role in raising labor productivity over time, with three major consequences. First, the steady-state growth rate (of output) becomes endogenous and is influenced by government policies. Second, the speed of adjustment to steady-state growth is faster, and enhanced learning further reduces adjustment time. Third, both steady-state growth and the optimal net rate of return to capital are higher than the sum of exogenous rates of technical change and population growth. Simulation results confirm the model’s faster speed of adjustment, while regression analysis explains a large part of divergent growth patterns across countries in terms of the extent of openness and human development and of the quality of fiscal policies.
