The Importance of Investment

“Someone is sitting under a tree today because


someone planted a seed a long time ago.”

Warren Buffett


To increase the productive capacity of the economy and allow us more choices, requires that we refrain from consuming all resources now and invest for the future.

Resources- land, labour, capital and enterprise – are dedicated to future production. Turning iron ore into machinery rather than cars, educating the innovators of tomorrow, and incentivising the use of new technology, are some examples of ways as a nation we invest in the future.

Some decisions or allocation of budget resources may pay dividends quickly; others take time, such as grants to research facilities or revising the school curriculum to include coding in the kindergarten school curriculum!

The funds available to increase the productive capacity of the economy (via investment) primarily come from the pool of national savings contributed by both by the private sector (households) and the public sector (government) via the financial sector.

Remember, to have more options and less scarcity; we need to make the economic ‘pie’ grow or, shift the production possibility curve out to the right.

Likewise for us households!

Another way of thinking about the size of the economy is via the simple circular flow of income model that looks at injections into the economy vs the leakages.

Think of it as a large above ground swimming pool. The more water that is pumped in (injections), the higher the level of water in the pool and more people can get in and get wet. Spring a leak and the water level falls meaning some swimmers need to get out. (= unemployment)

Injections are consumption expenditure (C), investment expenditure (I), government expenditure (G) and the sale of exports (X).

Leakages are saving (S), tax (T) and imports (M)

If injections are > leakages, the economy will grow.

If leakages are > injections, the economy will contract.



Consumption is the most significant contributor to demand in the economy. Maintaining consistent consumption is vital to keep people employed.

Regulating the level of consumption in the economy is one of the primary responsibilities and targets of economic management. Variations in consumption, both increases (in times of prosperity and strong business and consumer confidence) and decreases when the opposite conditions prevail, has significant impacts on the level of income, output, and employment in the economy.

Via the multiplier effect, any change in consumption has a ripple effect throughout the economy.

For example, currently, the federal government is providing a stimulus package to support consumption and businesses in the wake of the exogenous shock to our economy that has necessitated social distancing to combat COVID-19.

One of the cash injections will be in the form of two payments to Pensioners. Why? Because most pensioners are living on minimum incomes and so they are extremely likely to need to spend, rather than save the bonus payment.

Their marginal propensity to consume (MPC) is high.

The MPC is a measure of how likely a recipient of funds is to spend an extra (or marginal) dollar they receive.

If the MPC = 0.8 recipients will  spend 80 cents and save 20 cents

A $10 million injection into the economy, in this case, will result in a much more substantial $50 million stimulus to the economy.

Of course, this simple example assumes the recipients of their spending will have the same MPC. It may be higher or lower; nonetheless, the concept is evident. A carefully targeted injection into the economy will have a reasonably predictable compounded effect on consumption, incomes and employment.

provide incentives

to invest in bricks and mortar and are

very unlikely to ever remove those incentives





“Home Building Packs a Punch in Job Creation Stakes”

A new report from the  National Housing Finance and Investment Corporation reinforces the view that  “the residential construction sector punches well above its weight as an economic multiplier” and “understanding how residential construction activity may affect jobs and flow through to the broader economy is increasingly important… The Urban Developer June 19, 2020



But what if in times of uncertainty households save instead of spending?

All is not lost, nor is the stimulus ineffective.

They provide funds via financial institutions for firms to invest and increase their productive capacity. Provided you don’t stash your savings under the bed, (a leakage from the system) you are making it possible for firms to borrow and invest and build the capacity of the economy.

That constitutes a passive investment in the economy and our future collective welfare,


you can also do the same,

individually and proactively!


We can invest in our own and our family’s future by devoting some of our resources (time, income, assets, efforts and skill) to education and training to improve our earning capacity or saving to directly and deliberately invest in creating future wealth.
