This note shows that there are monetary equilibria in the model of overlapping generations that are in the core. Some equilibria have positive stocks of outside money in every generation. These equilibria are thus self-enforcing, and introducing money into an economy need not be tantamount to...

Equilibrium paths in economies of overlapping generations depend on the frequency of trade. In a standard example, determinacy obtains as the frequency of trades tends to infinity or trade occurs in continuous time. If time extends infinitely into the infinite past as well as into the infinite...

This paper presents sufficient conditions for the existence of a unique and globally stable steady state equilibrium for OLG economies with production. The conditions impose separate requirements on the utility and production functions. Moreover, the conditions do not require assumptions...

This paper explores how market power of agents on the capital market affects economic growth and output fluctuations in an overlapping-generations model with endogenous capital accumulation. Agents interact strategically by anticipating how their savings affect the return on savings in...

This article demonstrates that in the standard two-period lived overlapping-generations model with rational expectations, price-taking behavior of agents on the capital market is implausible. We show that market power reduces agents' savings relative to the price-taker benchmark such that less...

We take into account that envy (relative consumption concerns) is more pronounced in the present than in the future. We consider a Ramsey-type model in which agents differ only in their initial capital endowments but are identical in their exogenous parameters. Agents' preferences exhibit...

For an overlapping generations economy with varying life-cycle productivity, non-stationary endowments, continuous time starting at −∞(hence allowing for full anticipation), constant-returns-to-scale production and CES utility we fully characterise equilibria where output is higher than...

The paper reexamines the ethics of intergenerational risk. When risk re-solves gradually, earlier decisions cannot depend on the realization of later shocks and, consequently, some inequalities across generations are inevitable. To account for these inequalities, risky intergenerational...

We analyze the role of "the" utility discount rate and its implications to generation-specific and societal altruism and egoism, respectively, in a neoclassical framework. It is worked out clearly, that two different utility discount rates have to be distinguished: An (inverse)...

Decisions with long-term consequences require comparing utility derived from present consumption to future welfare. But can we infer socially relevant intertemporal preferences from saving behavior? I allow for a decomposition of the present generation's preference for the next generation into...
