Abstract: | In contrast to conventional, disaggregative testing of the law of one price, this study adopts an aggregative approach. Using a tradable/nontradable level of aggregation, a model is developed to test equality of the prices of tradables and nontradables domestically and equality of the price of tradables internationally. The disaggregative approach exhibits biases that lead to rejection of the law of one price. In contrast, the results of the aggregative technique for the law of one price are strongly positive and the limitations of the approach are found not to overcome its findings. |
