Demand-Led Growth – Government Spending and the Investment Share

In the long run, a higher rate of economic growth implies a higher share of investment in income. This will necessarily correspond to a lower combined share of other forms of spending. Knowledge of this point sometimes leads to unfortunate calls to cut back government spending as a means of boosting growth. Yet, if private investment can be said, in a long-run context, largely to be induced by income – which is consistent with the evidence (see, for instance, here, here and here) – then a sustained increase in the growth rate of government spending and other components of autonomous demand could be expected, through their direct impact on income, to induce higher investment. It is not at all obvious that the investment share in income would fall as a result of this process. To the contrary, there is reason to expect the investment share to rise and the share of other spending (and quite possibly government spending) to fall in consequence of demand-led growth of this nature. The purpose of the present post is to explain this possibility.

The Role of Government Spending in Fostering Global Growth

The neoliberal approach to economic growth of the past forty years has been to drive down real wages, deregulate the financial sector, privatize various government functions, cut social expenditures and reduce taxes on large corporations and the wealthy. The period has been characterized by sluggish growth and widening inequalities. In contrast, the markedly higher rates of growth achieved from the end of the Second World War until the early 1970s were sustained in a regime of steadily rising real wages, which were consciously linked through policy or collective bargaining to improvements in productivity. This approach to industrial relations was played out within a context of substantial direct public-sector involvement in the economy, tight financial regulation, high and steeply progressive taxation and a more equal distribution of income and wealth.

Institutions, Monetary Operations and a Demand-Led Global Economy

Macroeconomic controversies usually center on causation. Two questions of significance for policymaking concern output and growth:

  • Is output demand or supply determined?
  • Is economic growth demand or supply led?

If demand is the driver of output and growth, there will be considerable scope for government spending to influence the economy’s trajectory. If, instead, supply-side factors are determining, fiscal policy will be impotent other than possibly temporarily. Recent history suggests – much like the earlier history of the Great Depression and Second World War – that fiscal policy is important to the performance of the economy, and that demand matters. In my view, the causal significance of demand follows quite strikingly from Modern Monetary Theory’s institutional analysis of sovereign currencies together with the fully compatible Post Keynesian analysis of banking and endogenous money. Before getting into that, a brief summary of opposing positions on output and growth determination is perhaps warranted.

Is Public-Sector Labor ‘Productive’ in a State Money System?

An issue that troubles me in relating Marx to Modern Monetary Theory (MMT) is whether to apply the ‘productive/unproductive labor’ distinction to production that is monetized in a state money. Although I am not especially enamored of the distinction in general, it is particularly its application to public-sector activity in a state money system that strikes me as problematic. I ask the reader to countenance two propositions:

Proposition 1. All public-sector labor in a state money system is productive.

Proposition 2. Proposition 1, if true, would alter none of Marx’s central theoretical conclusions.

If the following argument is mistaken, maybe someone can set me straight, and it will then be clearer how to proceed in future.

Commander Keen

If you are of a certain age, you likely played Commander Keen. Cane’s run in the video embedded below was a world record at the time, but has since been beaten in a near flawless run by CapnClever. Even so, I like this video because of the amusing running commentary and chat that is conducted during game play. (There are some expletives, so any children watching might need to cover their parents’ ears.) The ‘death exit’ at the beginning of the second level is a glitch in which the player can allow Keen to die at the edge of the game’s map and then immediately save and reload to complete the level.

Heteconomist’s Not Especially Holy Christmas Message 2016

It’s that time of year again to try our hand at Holiday Time. It’s not easy, after fixating on economics, to switch our attention to something else. It seems advisable to do so only in stages. Accordingly, the first video installment below retains a distinctly economics flavor, perhaps leaning more toward the business end of the discipline. After that, though, things are likely to go somewhat haywire.

We’re Wealthier Now, We Can’t Afford That Anymore

Have you noticed how things we used to be able to do are beyond our capabilities now?

We finally reached a point where we were able to provide free university education. Then we grew wealthier, and some countries couldn’t afford it anymore.

Some of us still have universal public health care systems, but they’re increasingly a chronic burden. Maybe they made sense once, but it’s only a matter of time before they go. Sure, Cuba can do it, but they’re poorer than us.

Not Investing in Infrastructure, Culture and Knowledge IS the Burden We Place on Future Generations

If we were to believe most politicians, we’d be under the mistaken impression that government not investing today does future generations a favor. Leaving communications systems underdeveloped, road and transport networks crumbling, education and public health systems deteriorating, our cultural institutions eroding, developments in science and technology stagnating, and so on, will supposedly free future generations of any burden that might otherwise be imposed upon them.
