This paper proposes a general framework for analysing commodity tax competition under destination and origin principles, based on three possible tax spillovers: the consumer price spillover, the producer price/terms of trade spillover, and rent spillovers. A model is presented which can be extended to accommodate all three spillovers. Using this model, many of the results in the existing literature can be derived, compared, and extended.
