This paper develops a two-sector dynamic general equilibrium model of a small open economy in which production activities are accompanied by pollution emissions that have a negative effect on welfare. It is shown that the dynamic equilibrium may display indeterminacy (i.e., continuum of dynamic...

This study considers endogenous determination of domestic standards on products that cause negative consumption externalities in the presence of a preferential trade agreement (PTA) in a three-country world. In particular, we examine how a PTA affects the optimal levels of external tariffs and...

This note examines strategic import policies in a three-country model with vertical production and trade relationship. Reflecting horizontal and vertical effects of the import policy, each country's optimal policy can be either tariff or subsidy, depending on the relative numbers of upstream and...

This paper examines a differential game model of voluntary provision of a public good in which private agents' contributions accumulate over time and derives subsidy rules that achieve the socially efficient steady state. It is shown that the optimal subsidy rule is a simple one when agents use...

This paper examines an equilibrium growth model in which production activities generate environmental pollution that has a negative welfare effect and in which individual households' subjective discount rate is a function of individual consumption, which is internal to each household, and of...
