The role that investment-specific technological change played in generating postwar US growth is investigated here. The premise is that the introduction of new, more efficient capital goods is an important source of productivity change, and an attempt is made to disentangle its effects from the...

We discuss climate change and resource scarcity from the perspective of macroeconomic modeling and quantitative evaluation. Our focus is on climate change: we build a very simple “integrated assessment model,” ie, a model that integrates the global economy and the climate in a unified...

We document that, across households, the money consumption ratio increases with age and decreases with consumption, and that there has been a large increase in the money consumption ratio during the recent era of very low interest rates. We construct an overlapping generations (OLG) model of...

This paper proposes a new equilibrium concept organizational equilibrium for models with state variables that have a time inconsistency problem. The key elements of this equilibrium concept are: (1) agents are allowed to ignore the history and restart the equilibrium; (2) agents can wait for...

Since the work of Doepke and Schneider (2006a) and Meh and Terajima (2008), we know that inflation causes major redistribution of wealth between households and the government, between nationals and foreigners, and between households within the same country. Two types of monetary policy,...

Abstract In this paper I explore the quantitative implications for savings of population aging. In doing so, I pay particular attention to some features that have been partially over-looked in the literature. These features include the details of the population aging process, the initial...

Necessary conditions for equilibrium are that beliefs about the behavior of other agents are rational and individuals maximize. We argue that in stationary OLG environments this implies that any future generation in the same situation as the initial generation must do as well as the initial...
