This paper studies a dynamic equilibrium with small fixed transactions costs. We consider an overlapping generations economy with two assets of different liquidity. Trading the liquid asset does not involve transactions costs while trading the illiquid asset requires a fixed transaction fee....

Optimal forecasts are, under a squared error loss, conditional expectations of the unknown future values of interest. When stochastic demographic models are used in macroeconomic analyses, it becomes important to be able to handle updated forecasts. That is, when population development turns out...

We study the environmental and economic effects of public abatement in the presence of multiple stable steady-state ecological equilibria featuring reversible hysteresis. The isocline for the stock of pollution possesses two stable branches. Assuming that the ecology is initially located on the...

For worldwide fisheries production, two major trends emerge for the next decades: a significantly larger role for aquaculture and reduced output due to climate change impacts. While the former leads to an increase in cost, the latter affects natural regeneration. To address both impacts, we...

Computable general equilibrium (CGE) models and “convergence models” differ in their assessment of the extent to which demography influences economic growth. Here, I show that CGE models produce results similar to those of convergence models when more detailed demographic information is...

We develop a neoclassical growth model having a realistic demographic structure. We identify the critical channel of impact to be the intertemporal consumption allocation decision through the “generational turnover term”. Expressing the aggregate dynamics as a generalization of the...
