Existing literature on optimal patent policy and growth has been focused on the infinite horizon economy models. The lack of analogous analysis for an economy of finitelyliving consumers motivates the present study. We develop a simple quality ladder model of an overlapping-generations economy in the spirit of the canonical model by Grossman and Helpman (1991). Then we analyze the effect of cha...

Traditionally, the primary function of oligodendrocytes (OLGs) in the CNS has been considered to be myelination. Here, we investigated whether OLGs may play a trophic role, particularly during development. Neurotrophin expression was assessed in postnatal day 7 basal forebrain (BF) OLGs, using in situ hybridization and detection of myelin basic protein. Nerve growth factor, brain-derived neurot...

Dynamic Efficiency and Pareto Optimality in a Stochastic OLG Model with Production and Social Security We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium i...

This paper studies the efficiency of equilibria in a productive OLG economy where the process of financial intermediation is characterized by costly state verification. Both competitive equilibria and Constrained Pareto Optimal allocations are characterized. It is shown that market outcomes can be socially inefficient, even when a weaker notion than Pareto optimality is considered.

This paper builds on Cremer’s [3] seminal analysis which shows that (almost) complete cooperation can be achieved as an equilibrium in a game played by overlapping generations of players if the institution in which players cooperate is infinitely lived. We analyze a similar model in which the costs of cooperation are subject to random shocks. Even if these random shocks are very small, the rang...
