This paper examines the joint determination of long-run income per worker and capital utilization. Comparatively low (optimal) rates of capital utilization may arise in poor economies in response to weak underlying structural characteristics. The quantitative implications of variable capital...

Summary Using a calibrated neoclassical growth model, we address three questions: (i) how much growth should aid flows have produced in Sub-Saharan Africa over the last three decades? (ii) how much aid would be needed to attain the First Millennium Development Goal (MDG#1) of cutting poverty in...

<Para ID="Par1">In the present paper we advance a theory of pre-industrial growth where body size and population size are endogenously determined. Despite the fact that parents invest in both child quantity and productivity enhancing child quality, a take-off does not occur due to a key “physiological...</para>

This paper estimates the total effect of power outages on economic growth in Sub-Saharan Africa over the period 1995–2007. We pay close attention both to potential errors of measurement of African economic growth and to the endogeneity of outages. As suggested by Henderson et al. (American...

Empirically, a higher frequency of lightning strikes is associated with slower growth in labor productivity across the 48 contiguous U.S. states after 1990; before 1990, there is no correlation between growth and lightning. Other climate variables (e.g., temperature, rainfall, and tornadoes) do not...

Does prosperity lead to greater longevity? If so, what is the strength of the income channel? To address these questions we develop a life cycle model in which households are subject to physiological aging. In modeling aging we draw on recent research in the fields of biology and medicine. The...

This research examines the physical constraints on the growth process. In order to run, maintain and build capital energy is required to be distributed to geographically dispersed sites where investments are deemed profitable. We capture this aspect of physical reality by a network theory of...

The present paper shows that the savings motive critically affects the size and sign of scale effects in standard endogenous growth models. If the bequest motive dominates, the scale effect is positive. If the life-cycle motive dominates, the scale effect is ambiguous and may even be negative.

This paper examines the joint determination of long-run income per worker and capital utilization. Comparatively low (optimal) rates of capital utilization may arise in poor economies in response to weak underlying structural characteristics. The quantitative implications of variable capital...
