Coping with Externalities in Tourism - A Dynamic Optimal Taxation Approach

The paper studies optimal taxation (subvention) when tourism is associated with „multiple externalities“, using a simple dynamic model of a small open economy, which is completely specialized in the production of tourism services and populated by a large number of intertemporally optimizing agents. Depending on the volume of tourism production, the externality can be either positive or negative. We show that the first best optimum, achieved by a central planner, recognizing the externality, can be replicated in a decentralized economy by using a time-varying tax rate. This ensures that (i) the steady state of the first best optimum is reached and that (ii) the speed of convergence to steady state is socially optimal.
