We examine the role of tariffs levied on the imported production factor in a one-sector small open economy real business cycle model. We show that under perfect competition and constant returns-to-scale, the model may exhibit local indeterminacy and sunspots as tariff rates are endogenously determined by a balanced-budget rule with a constant level of government expenditures. Conversely, the economy in which the government finances endogenous public spending and transfers with fixed tariff rates is immune to indeterminacy.
