The paper examines the Porter and induced-innovation hypotheses in a firm model where: (i) the firmhas a vintage capital technology with two complementary factors, energy and capital ; (ii) scrappingis endogenous; (iii) technological progress is energy-saving and endogenous through purposive...

This paper extends the standard neoclassical model by considering a technology sector through which an economy with limited human capital attempts to catch up with a given "locomotive" pushing exogenously technical progress. In periods of technological stagnation, economies close enough to the...

This paper develops a theory of optimal fertility behavior under mortality shocks. In an OLG model, young adults determine their optimal fertility, labor supply and life-cycle consumption with both exogenous child and adult mortality risks. We show that a rise in adult mortality exerts an...
