The natural sciences have established a general scaling law that relates metabolism and body size of animals. Recently this association - known as Kleiber's law - has received deep theoretical foundation by network theory and has been fruitfully applied to explain various biological phenomena,...

This paper develops a bioeconomic Malthusian growth model. By integrating recent research on allometric scaling, energy consumption and ontogenetic growth, we provide a model where subsistence consumption is endogenously linked to body size and fertility. The theory admits a unique Malthusian...

We hypothesize that the timing of the fertility transition is an important determinant of comparative physiological development. In support, we provide a model of long-run growth, which elucidates the links between population size, average body size and income during development....

Drawing on recent research on allometric scaling and energy consumption, the present paper develops a nutrition-based efficiency wage model from first principles. The biologically micro-founded model allows us to address empirical criticism of the original nutrition-based efficiency wage model....

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 check":...

Unified growth theory predicts that the timing of the fertility transition is a key determinant of contemporary comparative development, as it marks the onset of the take-off to sustained growth. Neoclassical growth theory presupposes a take-off, and explains comparative development by...

A neoclassical growth model is augmented by a corporate sector, financial intermediation, and a set of tax rates. In this setting, capital structure is determined by the interplay between an advantage of debt finance resulting from the tax system and a disadvantage resulting from asymmetric...

Macroeconomic studies of tax policy in dynamic general equilibrium usually assume that reforms hit the economy unexpectedly and last forever. Here, we explore how previous results change when we allow policy changes to be pre-announced and of finite duration and when these facts are anticipated...

This article shows within a simple growth model how the make up of society affects economic performance when property rights are unenforceable. It investigates behavior of non-cooperative social groups that consume, produce, and appropriate resources either peacefully or through contest. For the...

We develop a simple model of labor market participation, human capital degradation, and re-training. We focus on how non-participation, as a distinct state from unemployment and employment, is determined by the welfare system in interaction with labor market conditions and personal...
