In this paper we propose a bootstrap version of theWald test for cointegration in a single-equationconditional error correction model. The multivariatesieve bootstrap is used to deal with dependence inthe series. We show that the introduced bootstraptest is asymptotically valid. We also analyze thesmall sample properties of our test by simulationand compare it with the asymptotic test and severalalternative bootstrap tests. The bootstrap testoffers significant improvements in terms of sizeproperties over the asymptotic test, while havingsimilar power properties. The sensitivity of thebootstrap test to the allowance for deterministiccomponents is also investigated. Simulation resultsshow that the tests with sufficient deterministiccomponents included are insensitive to the truevalue of the trends in the model and retain correctsize.
