Practitioners of development accounting assume that the private return on schooling equals its social marginal product. I show that this assumption is inconsistent with the mathematical structure of a multiplicative production function, which specifies that the private return is only a fraction...

We model an environment in which different vintages of capital with their different productivities coexist. A reduction in the cost of investment induces investment in new capital which raises both measured capital and measured productivity simultaneously. We calibrate this model to...

In this paper we analyze tax and transfer choices in an OLG economy with capital accumulation and endogenous growth coming from public investment, such as education. We solve for a Markov perfect equilibrium when electoral competition targets the votes of young and old households. We find that...

We analyze the sustainability of intergenerational transfers in politico-economic equilibrium. We argue that these transfers naturally arise in a Markov perfect equilibrium in the fundamental state variables. In contrast to earlier literature, our explanation does not resort to altruism,...
