Income Gap and Marginal Tax Rate 1917-2006

Catherine — Mon, 14 Jul 2008 02:18:09 +0000

From the Nation. The top graph shows the average income of the top o.o1% compared to the bottom 90%. The higher the peak the bigger the gap between the two groups. In 2006 you would need an income of over $10 million to make it into the top 0.01% while your income would have to be less than $100,000 to be in the bottom 90. The second graph shows the marginal tax rate over the same time period. Here is graph I created plotting similar data.

Average Income: PreTax vs AfterTax 2005

Catherine — Mon, 17 Mar 2008 00:46:15 +0000

I created this graph showing the average income for different household percentiles, comparing pretax income and aftertax income. The minimum income threshold for each percentile is noted in the graph.

Gross Domestic Product by Industry: Winners & Losers

Catherine — Mon, 02 Jul 2007 20:28:33 +0000

Looking at the Industry Sectors of the US economy can help illuminate why, over the last 30 years, someone working in a growing industry (like Finance) may have done better than someone working in a shrinking industry (like Manufacture). Note: the data measures value-added; for example the services provided by a doctor is counted under Heath Care but the production of medical equipment would be found in Manufacture.

All Sources of Income for Top 0.01 Percent

Catherine — Mon, 04 Jun 2007 00:08:51 +0000

In my earlier post on Sources of Income of the super rich I plotted the percentage of income that comes from wages, entrepreneurial income, dividend income, interest income, rental income, and capital gains for the Top 0.01 percent. Here I am posting the same data but this time all income sources are on the same graph.

A few items that caught my attention: the decline (starting in the 1930s) of the importance of Dividend income which was replaced in part by “Entrepreneurial” income then Capitals Gains and finally in the 60s by Wages. Also in the 70s and 80s Interest income becomes more important no doubt due to the high interest rates during those decades.

Sources of Income for Top 0.01 Percent

Catherine — Sun, 06 May 2007 23:41:27 +0000

In my earlier post on Sources of Income of the super rich I plotted the percentage of income that comes from wages, entrepreneurial income, dividend income, interest income, and rental income for the Top 0.01 percent; but this did not include capital gains. In 2005 capital gains was 18% of the income of the super rich (if you exclude capital gains when determining the Top 0.01 percent).

In the graphs below, I have plotted the all 6 income sources for Top 0.01% (this time including capital gains as one of the income sources).

Sources of Income for Top 0.01 Percent (excluding capital gains)

Catherine — Tue, 17 Apr 2007 01:53:36 +0000

In my earlier post I plotted the percentage of income that comes from capital gains for the Top 0.01 percent. (In 2005 it was 18% if you exclude capital gains when determining the Top 0.01 percent and 51% if you include capital gains when determining the Top 0.01 percent).

In the graphs below, I have plotted the other income sources for Top 0.01% (excluding capital gains when you rank the families). The question I am trying to answer: since most of the income was not from capital gains in the original graph, what are the sources of the unaccounted for income?

Capital Gains and the Top 0.01 Percent

Catherine — Wed, 11 Apr 2007 02:19:25 +0000

The following two graphs look at the capital gains of high income earners but they need a little explanation. Capital gains are a volatile component of personnel income. For example, depending on what is happening in the stock market capital gains can make up a relatively large or small part of the total income. Also capital gain tend to be realized in a lumpy way. Every year there are families who have a one-time jump in income due to the sale of a house, a business or some other assets like stocks. In these cases the income for those families might qualify them for the Top 1%, Top 0.1%, or Top 0.01% but only for a single year.

When you are choosing which families are members of the high-income “super rich” you have to make a decision whether to include capital gains when you rank the families by personnel income before calculating the share of income that is capital gains. The blue graph excludes capital gains when determining the top 0.01%, the purple graph includes capital gains when determining the top 0.01%

NYTimes: Income Gap Is Widening, Data Shows

Catherine — Thu, 05 Apr 2007 02:12:19 +0000

The New York Times had an income graph in a Mar 29th article that reminded me of the Income/GDP post I made last October. The difference is that I was looking at the share of GDP going to the top 10% as compared to the bottom 90% rather than the share of individual income going to the top 1% and bottom 90%. However, both graphs rely on the IRS data collected by Saez and Piketty. One critique I had about their graphic: by using a different scale for the second graph (the average income for the early 2001-05) it was difficult to compare it to the larger graph. This means the relationship between the two graphs was not very clear.

US Income of Top 0.1 Percent vs Marginal Tax Rate

Catherine — Sun, 25 Mar 2007 01:04:08 +0000

While the graph in my previous post compared the Top 0.1 percent in different countries, here I made a direct comparison between the US Top Marginal Tax Rate and the Top 0.1 percent income share since 1913. This time just focusing on the United States.

{Click on the graph to take a closer look}

Again the effect by the two World Wars is there but what I wanted to emphasize is the relationship between the share of income going to the very wealthy and the change in the top marginal income tax rate.

The income data can be found on Emmanuel Saez’s web site. I found the marginal tax rate for the United States in the SOI Bulletin Historical Table A at the IRS site via truthandpolitics.org

Comparing Income of Top 0.1 Percent in Five Countries

Catherine — Thu, 15 Mar 2007 03:13:12 +0000

I created these graphs to show the change in the share of income going to the top 0.1%, comparing the United States to Canada, United Kingdom, France, and Japan from 1913-2004.

{Click on the graph to take a closer look}

The effect by the two World Wars is clear but what is more subtle is the effect on the share of income going to the very wealthy due to the change in the top income tax rate. This could be due to attempts by the very wealthy to hide their income from the IRS or else having a higher tax rate will impact the distribution of income or both. I didn’t have the marginal rates for the other countries but it would be interesting to see if they have a similar relationship between the share of total income captured by the Top 0.1 percent and income tax rates.
