The socially optimal allocation has been regarded to be unspecifiable because of utility’s interpersonal incomparability, Arrow’s general possibility theorem, and other factors. This paper examines this problem by focusing not on the social welfare function but instead on the utility...

This paper examines the socially optimal allocation by focusing not on the social welfare function but instead on the utility possibility frontier in exogenous growth models with a heterogeneous population. A unique balanced growth path was found on which all of the optimality conditions of all...

This paper studies social welfare in a heterogeneous population under the criteria of efficiency and sustainable heterogeneity. As is well known, heterogeneity in time preference results in substantial inequality. This paper shows that, even if households have heterogeneous preferences, there is...

This paper presents an endogenous growth model in which the economy grows without either scale effects or population growth. The key mechanism is substitution between investments in capital and technology when firms face increasing uncompensated knowledge spillovers. The model indicates that, as...

Many claim that fluctuations in US private savings help to create and to sustain global imbalances because of their influence on the current account deficit. To test this claim, this paper investigates the determinants of aggregate household savings using a panel of 18 developed countries for...

This paper shows that a Nash equilibrium consisting of strategies of choosing a Pareto inefficient transition path is selected by households even without frictions as a result of the revealed government failure in supervision of financial markets. The Pareto inefficiency causes the generation of...

This article investigates how wealth and capital gains affected household consumption in the USA in the period 1989-2004. The empirical evidence brought so far by a large literature that investigates the role of wealth shocks on consumption is mixed, due to the low quality of the data more...

This article investigates how wealth affected household consumption in the USA in the period 1989-2007. Previous empirical results are mixed, mostly because of the low quality of the data more readily available. We combine information from the Consumer Expenditure Survey and the Survey of...

How does household wealth influence consumption? The empirical evidence brought so far by the literature is unclear, mostly because of the low quality of the data more readily available: aggregate data, cross sections and panel datasets lacking important variables all present major shortcomings...
