Measuring the Cost of Living in Mexico and the United States
利用美国和墨西哥条形码级消费品价格和支出数据，测算墨西哥相对于美国的价格指数，发现比国际比较项目指数低23%，并分解为插补、抽样、质量和品种偏差。
We use a dataset with prices and spending on consumer packaged goods matched at the bar code level across the United States and Mexico to measure the price index in Mexico relative to the United States. Mexican prices relative to the United States are 23 percent lower compared to the International Comparisons Project’s (ICP) price index. We decompose the 23 percent gap into the biases from imputation, sampling, quality, and variety. Quality bias increases Mexican prices by 48 percent. Imputation, sampling, and variety bias lowers Mexican prices by 11 percent, 13 percent, and 33 percent, respectively.
