This study examines the empirical relationship between tourism and the competitiveness of a destination. It uses the cointegration and error correction model (ECM) in a bivariate context as a precondition to apply the Granger causality test. This procedure was carried out in the case of Puerto Rico\u27s tourism industry during 1960–2004. The study found cointegration in the intertemporal rather than the contemporaneous effects, as well as a one-directional causality running from changes in tourism spending to changes in competitiveness. This result highlights the long-run equilibrium spending behaviour of tourists as a major concern of destination managers
