In this paper we extend the Lucas (1988) endogenous growth model to include sector-specific external effects and depreciation in both sectors. We derive analytically, the restrictions on the parameter space that are necessary and sufficient for the existence of balanced growth paths and equilibria. We demonstrate that in contrast to the original model, with the addition of an external effect an...

This paper examines the relationship between two types of preference: preference of intertemporal choices and preference towards risk. In the simplest form of the constant relative risk aversion utility function, the intertemporal elasticity of substitution (IES) and risk aversion has an inverse relationship. However, there is no empirical evidence that suggests this inverse relationship holds....

In this paper we study the effects of the intertemporal elasticity of substitution in consumption (IES) on Balanced Growth Path fertility choice in a dynastic model. We find that both the qualitative and quantitative properties of the model are highly sensitive to this key parameter. We give analytic comparative statics results that show why this is true. In versions of the model in which the I...

Do Workers Work More When Wages Are High? Evidence from a Randomized Field Experiment Most previous studies on intertemporal labor supply found very small or insignificant substitution effects. It is not clear, however, whether these results are due to institutional constraints on workers’ labor supply choices or whether the behavioral assumptions of the standard life cycle model with time sepa...

This paper examines intertemporal risk–taking in a stochastically growing economy with externalities in human capital accumulation where agents have preferences for social status. In order to isolate the effects of status concerns on long–run expected growth, the analysis is embedded in a nonexpected utility setting, which disentangles the effects from risk aversion and intertemporal substituti...

To justify substantial emission reductions, recent literature on cost-benefit analysis of climate change suggests discounting environment consumption with an environmental discount rate instead of a consumption discount rate that is usually used in cost-benefit analysis. The present study clarifies that whether or not this dual-rate discounting approach succeeds in justifying substantial emissi...
