Only a few months ago, the Chair of the NZ Green Investment Fund (NZGIF) and Chancellor of the University of Auckland, Cecilia Tarrant, visited my "Law and Economics" class. Why? She's a lawyer who worked in "structured products" and "real estate finance" at Morgan Stanley in New York - and knows a Kiwi friend of mine who's at Google there. She presented some slides on the NZGIF. The first slide below is very green. The second features "NZGIF Solar Finance". The third shows how NZGIF has created a structure, via its Solar Finance vehicle, that "provides a simple and repeatable financing solution for solar energy". Its "cornerstone partner" is a company called Solar Zero, which provides an "investment grade" asset. Chancellor Tarrant is the nicest, friendliest person in the world - though I'd like to meekly comment that Solar Zero was put into liquidation two weeks ago and may end up costing the taxpayer, who is funding NZGIF, $100 million dollars. Turns out the structure that the Green Investment Fund provided was not "simple" nor "repeatable". Turns out its "cornerstone partner" was not made of stone, but subject to liquefaction. The power point slides are great and colorful, although I do wonder maybe in need of a little revising for next year's class. The NZ Green Investment Fund should itself be liquidated. NZ already prices carbon via our Emissions Trading Scheme. We can't afford "picking winner" subsidies when our economy has stagnated. Have the Greens thought about how scarce resources should be allocated between solar panels & helping the poor? Do they think this $100 million was better spent on panels - or on taking 100 families out of poverty? My preference is the latter.

The Productivity Commission told us that NZ has a productivity problem; how Kiwis are so dim & lacking in skills we don't know how to add value to products. It never made sense. Kiwi workers are greatly valued all over the world. Fly a Kiwi to Australia or the US and hand them capital to work with (machines, equipment, super computers, infrastructure) and they will be as productive, more so, than others. We split the atom. NZ runs a space program - the largest private one in the world - after Space X. The UK can't - Richard Branson's Virgin Galactic is a bankrupt joke. Dr Shane Legg from Rotorua founded the world's first, most influential Artificial General Intelligence company. Elon Musk and Kiwi citizen Peter Thiel were desperate to buy it ahead of Google, since it changed the future. When it comes to education, we're told NZ is bad at Maths, but international scores like PISA rank our average above the US. Our literacy rates are in the top part of the world's distribution.
So what's wrong in NZ and how do we fix it? To answer, we must first define Total Factor Productivity (TFP). As this is a Blog, let's take liberties with Maths, and not discuss influential American economist Robert Solow, who invented the ideas behind it. Here's a definition of TFP: Output = TFP * Labour * Capital. In words, Output (measured by GDP) is produced by Labour and Capital (multiplied together here). Say 1 person uses 1 unit of capital to produce 3 units of output. TFP measures the technology behind the production. In this case, it equals 3 (i.e., 3 = Output = 3 * 1 * 1) and GDP per capita is 3 (=3/1). Below is a graph of Total Factor Productivity in NZ & Australia over the past 50 years:
How has NZ done? Before the early 1980s our Total Factor Productivity was higher than Australia's. It began turning down due to an external factor - our declining Terms of Trade during the oil shocks. After1988, NZ's TFP has grown at the same rate as Australia's. Technology is rising here just like the best of them. But our GDP per worker is languishing:
Whereas we had similar per capita incomes as Australians 50 years ago, now they're nearly 40% better off than us. How can you reconcile the above two graphs? Whereas Australians (Americans also) invested and have built up capital, Kiwis did not. We have less capital to work with compared to them. Our roads are harder to drive, our transport & technical equipment suffers under-investment & buildings have become run-down, by comparison. Here's proof:
Although in 1974 Kiwis had more capital per worker than Aussies, now they have 50% more. Using our example above, assume capital rose from 1 to 2 units in NZ over the past 50 years, but rose from 1 to 3 units in Australia (with Total Factor Productivity remaining the same & labour staying at 1 unit). Then GDP per capita in NZ would've risen from 3 to 6 (= TFP * Labour * Capital = 3 * 1 * 2) but in Australia from 3 to 9 to (= 3 * 1 * 3). So their incomes would now be 50% higher than ours. Its an example, but (roughly) what's happened.
The implications of these graphs are astonishing. The PM said in his Parliamentary Maiden Speech how NZ suffers a 'productivity disease'. It does not. Our Total Factor Productivity, which measures technology & innovations, has been rising for 40 years at the same pace as Australia's. But NZ has suffered weak levels of investment, leading to a low capital base. The PM says National's "plan is to focus on the 5 levers of prosperity & productivity: education & skills, infrastructure, technology, business environment & connections with the world". He should sell his shot gun and buy a silver bullet. NZ must fund more investment using overseas & domestic savings. We must tear down walls stopping foreign savers investing money here (& curtailing returns even if they do). We must cut red-tape that hampers all investors, domestic & foreign. We must ramp up domestic savings with mandatory accounts (that's why folks like me promote Singaporean or Australian-style systems). America doesn't need them - the US dollar is the world's Reserve Currency - everyone wants to invest there.
The PM has one job to do to return NZ to being a rich nation - up investment and the savings that support it.
