Study title

The dataset provides the price indices computed for the academic paper "Price and Global Inequality", available at https://www.xavierjaravel.com/papers. The data has been created as part of the project addressing two questions: (1) What are the implications of prices changes for inequality and standards of living? (2) To what extent do the price effects induced by policies alter the cost-benefit analysis of these policies? Despite extensive research, we currently lack detailed data as well as various empirical and theoretical tools to appropriately answer these questions. These questions are fundamental because it is well-known that individuals across the income distribution purchase different baskets of goods and services. Therefore, changes in prices or product availability over time can potentially have an important impact on inequality.This project asks two questions: (1) What are the implications of prices changes for inequality and standards of living? (2) To what extent do the price effects induced by policies alter the cost-benefit analysis of these policies? Despite extensive research, we currently lack detailed data as well as various empirical and theoretical tools to appropriately answer these questions. These questions are fundamental because it is well-known that individuals across the income distribution purchase different baskets of goods and services. Therefore, changes in prices or product availability over time can potentially have an important impact on inequality. Likewise, differences in prices across countries can have a profound impact on standards of living across countries. The few studies that have investigated these questions have used "macro" data (at a high level of aggregation), but I have shown in previous work (Jaravel 2017) that it is crucial to use "micro" data (i.e. very disaggregated data, at the product level) to accurately answer these questions. We know that policies may have large price...
