Per-capita real consumption for both the bottom and top income quintiles has been trending up. AEI economist argue that this is more important than income inequality.
I had another great conversation with Aparna Mathur of the American Enterprise Institute last week (we last talked about a worrying "labor mismatch" in the U.S.). AEI is generally regarded as a conservative think tank, but regardless of your politics, it's been putting out some interesting research lately, and Mathur is an excellent explainer when it comes to labor and tax issues.
With Kevin Hassett, also of AEI, she's authored a new paper, titled "A New Measure of Consumption Inequality." Here's a sample:
Economists have widely acknowledged that consumption is a better measure of economic welfare than income. In general, individuals are better able to smooth consumption rather than income over their lifetimes, making consumption a more informative indicator in the study of inequality. Unlike income, consumption remains relatively steady throughout life since individuals borrow during years with low income and save in high-income years. Using consumption as the relevant measure of inequality, most studies conclude that, contrary to popular belief,inequality has remained fairly steady over the past thirty years. Our study retains the focus on consumption inequality and arrives at a similar conclusion.
