1/8/19: Wages vs GDP growth: when economic growth stops benefiting workers

I have posted earlier some data on the gap between real GDP and real disposable income per capita in the U.S. (see here: https://trueeconomics.blogspot.com/2019/08/1819-debasement-of-real-disposable.html) that evidences the longer-term nature of the ongoing debasement of real incomes in the repeated cycles of financialisation of the U.S. economy. Here is another view of the same subject matter:

Per chart above, consistent with my arguments in the case of disposable income, U.S. labor incomes have been sustaining ongoing deterioration relative to overall economic growth since at least the 1970s. In fact, the current expansionary cycle (yellow line) shows relatively benign speed of deterioration in real wages or labor income share of total real GDP, although the length of the cycle means that the total end-of-recession-to-present decline of ca 54 percent is deeper than that in the expansion of the 2000s (decline of 50 percent).

A different view of the same data is presented below, plotting historical gap between wages and GDP over longer horizon and showing expansion-periods' averages, contrasted against Trump Administration tenure average:

Once again, all evidence points to the decreasing, not increasing rate of wages fall relative to GDP over the years.

Of course, the effects are cumulative, which means that our perceptions of labor share collapse and the amplifying pressure on labor income earners in the economy is warranted.

1/8/19: Debasement of Real Disposable Income share of GDP: Historical Trends

I have been crunching some data recently on the historical gap between real GDP growth and wages/income of households. Some of this work will be forthcoming in an article due later this month, so keep an eye out for it. Some of it is post-dating the article submission. Here is an example of the latter. The following chart plots index of real GDP from 1Q 1959 through 1Q 2019 against the index of real disposable income per capita. Both indices are set at 100 at 1959 average.

There are 5 distinct periods over which growth in real GDP moved further and further away from growth in real disposable income. All are associated with monetary accommodation periods post-recessions, and all are associated with increasing post-recession financialization of the U.S. economy and financial or real estate asset booms.

Interestingly, the current rate of acceleration in the gap between economic growth and disposable income growth is... underwhelming. It pales in comparison to what was witnessed in the 1980s, 1990s and 2000s. To see this, consider the chart showing this gap by itself:

Despite our commonly-expressed public, media and analysts' perceptions of the declining share of economic growth going to disposable personal incomes being a new (current) phenomena, the reality of historical data paints a different picture. Most of declines in the share of economic activity accruing to wages, bonuses and investment and retirement incomes have taken place in previous decades, with the ratio of real GDP to real disposable income being relatively stable from the start of 2013 on. Prior to that rate of the decline in the relative share of disposable income has been less sharp from 1999 through 2012, when compared against all other decades.

The debasement of real incomes has been a steady and historical continuous process over the last 60 years.

2/4/2012: Impact of the middle class on economic, social and political institutions

A fascinatingly interesting study of the effects the middle class has on economic, social and political institutions.

The World Bank Policy Research Working Paper 6015: "Do Middle Classes Bring Institutional Reforms?" by Norman Loayza Jamele Rigolini Gonzalo Llorente (link here - emphasis mine) "examines the link between poverty, the middle class and institutional outcomes using a new cross-country panel dataset on the distribution of income and expenditure." The data "spans 672 yearly observations across 128 countries" allowing the authors "...to gauge whether a larger middle class has a causal effect on policy and institutional outcomes in three areas:

• social policy in health and education 
• market- oriented economic structure and 
• quality of governance." 

The study finds that "when the middle class becomes larger (measured as the proportion of people earning more than US$10 a day),

• social policy on health and education becomes more progressive [expansion of share of these expenditures to GDP], and 
• the quality of governance (democratic participation and official corruption) also improves. 
• This trend does not occur at the expense of economic freedom, as a larger middle class also leads to more market-oriented economic policy on trade and finance." 

From data (econometrics) perspective: "These beneficial effects of a larger middle class appear to be more robust than the impact of lower poverty, lower inequality or higher gross domestic product per capita."

The causality of the latter effect is itself an interesting point: "That may be linked to the evolution of the middle class: they are more enlightened, more likely to take political actions and have a stronger voice. They also share preferences and values for policy and institutional reforms, as well as higher stakes in property rights and wealth accumulation."

The authors note that their results show that "the indicators of poverty and inequality are also relevant determinants for social policies, economic structure, and governance quality, but not always in the expected way or with the consistency shown by the middle class measure. For instance, a decrease in income inequality seems to produce a decline in official corruption (as possibly expected) but also a reduction in democratic participation (which may be harder to explain). Similarly, a decrease in the poverty headcount appears to induce a liberalization of international trade but also, surprisingly, a constriction of credit markets."

Fascinating stuff, in my view.
