Hai-Ha Pham et al., « Effects of Wariness on Economic Growth in Overlapping Generations Models », HAL SHS (Sciences de l’Homme et de la Société), ID : 10670/1.1e8912...
We introduce the notion of wariness, defined as a concern for the lowestlifetime utility, in overlapping generations models and explore its effects oneconomic growth. In an exogenous growth model, under standard assumptions,we prove that the capital stock converges to a steady state. We then exploreconditions under which this steady state is increasing (or decreasing) in thewariness level. We also provide a necessary and sufficient condition for thedynamic efficiency of the intertemporal equilibrium. In endogenous growthmodels (à la Romer (1986) or à la Barro (1990)), we show that the growthrate of capital stock per capita in the economy with wariness is lower (higher,respectively) than that in the economy without wariness if and only if the capitalreturn is high (low, respectively).
