The growth effects of intellectual property right (IPR) protection are examined in a quality-ladder model of endogenous growth. Stronger IPR protection, which reduces the probability of imitation, raises the reward for innovation. However, stronger protection reduces the number of competitive...

This paper examines the economic growth effects of limited availability of higher education in a simple endogenous growth model with overlapping generations. With limited availability, the scarcity of human capital keeps its price high and distributes a larger share of the aggregate output to...

This paper presents an overlapping generations model with technology choice and credit market imperfections, in order to investigate a possible source of underdevelopment. The model shows that a better financial infrastructure that provides stronger enforcement of contracts facilitates the...

This paper examines a mechanism of liquidity-preference fluctuations caused by people's learning behavior. % about the frequency of a liquidity shock. When observing a financial shock, they rationally update their belief so that the subjective probability of encountering it again is higher,...

We study structural change in a simple, two-sector endogenous growth model and show that the presence of commodity-specific consumption externalities can be a source of structural change. When the degrees of consumption externalities are different between different goods, the two sectors grow at...

This paper explores optimal environmental tax policy under which duopoly firms strategically choose the location of their plants in a simple three-stage game. We examine how the relationship between the optimal emission tax and the choice of location of duopoly firms affects the welfare of the...

We specify a stochastic economy-climate model, adapting Nordhaus' deterministic economy-climate model by allowing for Weitzman-type stochasticity. We show that, under expected power utility, the model is fragile to heavy-tailed distributional assumptions and we derive necessary and sufficient...

This paper studies the interplay between climate, health, and the economy in a stylized world with four heterogeneous regions, labeled 'West' (cold and rich), 'China' (cold and poor), 'India' (warm and poor), and 'Africa' (warm and very poor). We introduce health impacts into a simple integrated...

This paper explores the roles of internal and external habit formation in a simple model of endogenous growth with overlapping generations. Unlike the representative agent settings in which the distinction between internal and external habits may not yield significant qualitative differences in...
