Canadian Megatrends: Top 1% income share and median age

Statistics Canada just came up with a study on the top income share of the top 1% in Canada. As I have explained elsewhere, my view of inequality is that: a) it has increased; b) not as much as we think; c) a lot of the increase is from desirable factors (personal utility maximization differing from income maximization or international immigration) or neutral factors (demography, marriage); d) that the inequality that is worrisome stems either from birth or government manipulations of the market and; e) that those stemming from government manipulations, direct (like subsidizing firms) or indirect (like the war on drugs which means that a large number of individuals are jailed and then released with a “prison earnings penalty” which stymies their income levels and growth), are the easiest to fight.

The recent Statistics Canada study allows me to make my point again with regards to element C of my answer. As I looked at their series, all I could think was “median age”. A lot of the variations seem to be related to the median age of the population. I went back to the census data I had collected for my book and plotted it against the data. This is what it looks like.

medianage

Why would there be a relation? Well, each year you measure the income distribution, the demographic structure of that population changes. As it grows older, you have more people at the top of their earnings curve relative to those at the bottom. Not only that, but earnings curve seem elongated in recent times – we live longer and so some people work older as witnessed by increased labor force participation rates above a certain age closer to retirement. And the heights of the earnings curve are now higher than ever before while we also enter later into the labor market.

Now, I am not sure how much aging would “explain away” rising inequality in Canada, but there is no point denying that it does explain some of it away. But, I would not be surprised that a large part is explained away. Why am I saying that? Because of this paper on Norway’s age structure. 

In Norway, the median age in 1950 was much higher than it was in Canada back then and today, it is roughly the same as Canada (although Canada has had a steeper increase in inequality). And according to the paper on Norway, adjusting for composition bias in inequality measures caused by aging, eliminates entirely the upward trend in that country. In fact, it may even reverse the trend whereby inequality adjusted for age has actually declined over time. This is a powerful observation. Given that Canada has had a steeper increase in median age, this suggests that the increase in inequality might be simply the cause of a statistical artifice.

Power and Happiness (President Obama in India)

There is widespread confusion around between two ideas that should be easy to separate from each other. I keep bumping into it. I had several lengthy discussions of it with strangers on Facebook. Some were of the left, some of the right. I found it in my morning paper under the pen of no less than columnist David Brooks of the New York Times (“Midwest at Dusk”11/7/1)).

I refer to the confusion between the happiness of a country’s citizens and the country’s standing in the world. David Brooks wrote:

“If America can figure out how to build a decent future for the working-class people in this (mid-Atlantic) region, then the US will remain a predominant power. If it can’t, it won’t.”

Like this.

President Obama’s post- “shellacking” visit to India is a good time to clear the confusion.

It may be that there is some sort of connection between the happiness of a country’s citizens (or some) and being a “predominant power.” It may be but it’s far from obvious. You would have to demonstrate it. It would be hard; casual evidence does not support the idea. Deeper research does not either. Continue reading
