Five Myths

Five Myths
1. Long-run trends:– Myth #1: Rise in income inequality partly (or largely) driven by
rising within-firm inequality (e.g., CEO pay)
– Myth #2: Income risk has been trending up in the past 40 years.
2. Business cycle:
– Myth #3: Income risk over the business cycle is...
mostly about countercyclical variance of shocks
– Myth #4: Top 1% are largely immune to business cycle risk
3. Life-cycle:
– Myth #5: Idiosyncratic income shocks can be modeled fairly wellwith a lognormal distribution.

Our findings, cont’d
1. Result 1: Inequality rose across the entire wage distribution.Contradicts typical media accounts that rising inequality == risingtop income shares.
2. Result 2: Almost all of the rise in wage inequality happenedacross firms, i.e., by rising gap in the average pay across firms.
– Almost no change in pay inequality within employers, except inmega-firms.
– Q: What is driving the rise in between-firm inequality?
I Answer: 1/2 rising segregation, 1/2 increased sorting.
3. Next question: Is the CEO pay driving rising inequality?

Rise in Income Inequality
The primary reason for increased income inequality inrecent decades is the rise of the supermanager.
Piketty (2013, p. 315)
Wage inequalities increased rapidly in the United States andBritain because US and British corporations became muchmore tolerant of extremely generous pay packages after1970.
Piketty (2013, p. 332)
A key driver of wage inequality is the growth of chiefexecutive officer earnings and compensation.

How About in Europe? Robustness
I We find exactly the same patterns for Sweden, Germany, andFrance:
– flat shock variance, procyclical skewness (Busch, Domeij,Guvenen and Madera, 2016; and Busch, Fialho, Guvenen, 2016).
I Moving from individual to household income, as well asincorporating government policy has little effect oncountercyclical left-skewness in the US.
I Gov’t policy more effective in Germany and Sweden
I ) Procyclical skewness of income shocks is a commonfeature of modern business cycles.

Firm-level Data
I Salgado, Guvenen, Bloom (2016): examine firm level variables ina panel of firms covering 44 countries:
– growth rate of sales, profits, employment, inventories– stock prices
I Robust evidence of procyclical skewness for all variables in 90%of the countries.
I Kehrig (2016): estimates firm-level TFP for US firms and finds nocyclicality in variance, but procyclical skewness.

Final Thoughts
I Public funding for collecting micro panel data for researchpurposes is woefully inadequate.
I To provide perspective:– NASA’s annual budget: ~20 Billion dollars
– International Space Station total cost: ~150 Billion dollars.
– All worthy efforts. Now consider this:
– US gov’t transfer payments in 2014: ~1.9 trillion dollars.
I For micro research on distributional issues, PSID’s annual budget(only US panel with consumption data): ~3 million dollars!
I Increased public funding for good quality data is essential forgood quality economic research.

Final Thoughts, cont’d
I We have played the “blind men and the elephant” for too long.
I There is hope: fantastic new datasets becoming accessible:
– Earnings: from IRS, SSA, and LEHD through various calls forproposals.
– Administrative data for Europe is especially impressive.
I Challenges: Data on consumption.. still very limited.
– Still there is hope: Private companies (Mint.com, Credit agencies)and research products (Michigan-Berkeley project) are becomingmore useful for researchers.
I I hope these new facts will feed back into theory and policy work.
