  1. How Different Studies Measure Income Inequality in the US

You’ve probably heard claims about middle class American income stagnating over the past decades and most of the gains in productivity going to the top X%. The following table lists studies that looked at income trends in the US over time. Which of these methods of income analysis sounds like it’s closest to measuring something you’d actually be interested in knowing?

Analyses of American income from 1979—2014
Income concept Adjust for household size Unit of analysis, 2014
Gross income as reported on tax forms without government transfers No 165 million tax filers
Pretax, postcash transfers and no employer benefits No 123 million households
Pretax, postcash transfers and no employer benefits Yes 186 million independent adults
All national income including homeownership and government services No 234 million adults ago 20 and over
Posttax, posttransfer income with health benefits Yes 117 million households
Posttax and post- and noncash transfers and employer benefits Yes 310 million people

By presenting the analysis plans without the corresponding results, you can arrive at a judgment with a clean conscience—no need to fear that you’re simply approving the study with your favored result. When you’re ready to see what studies and results these descriptions correspond to, look at Table 1 in the linked PDF.

  1. Relationship between the Chinese housing and marriage markets

Housing prices in some cities in China have increased more than tenfold in the past decade. They appear to be rising too fast relative to the growth of income.

[…]

Due in part to the one-child policy, there were 120 Chinese men for every 100 Chinese women as of 2005—in some provinces this ratio is as high as 130 to 100. […] One of the most visible symbols of this status competition comes through housing. […] This places a lot of pressure on Chinese families with sons to demonstrate their value through homeownership.

[…]

We found that home prices are higher and home sizes are bigger in cities with more skewed sex ratios. Strikingly, the sex ratio imbalance explained between half and one-third of the increase in housing prices in 25 major cities between 2003 and 2009.
