In a recent report the OECD praised the government’s aim to "increase productivity" in the New Zealand economy.   Ever since National came into power, the catch phrase productivity has been thrown around with reckless abandon – treated as both our saviour in the current crisis and the destitute child that was abandoned by the previous Labour government.

However, all this talk of productivity is a bit ambiguous.   If we don’t try to understand the trade-offs that are involved, and whether New Zealand as a society is willing to pay those costs for greater production, the strict focus on productivity alone will lead to bad policy.

Productivity is a surprisingly vague term given its importance in economics.   The essence of productivity is as follows: when an industry or an economy is more "productive", it can make more output with the same amount of input.

This definition indicates that productivity isn’t a goal in itself.   The goal of policy should be to support domestic economic activity (efficiency), while ensuring that the other issues that society values (equality, fairness, justice, etc) are taken into account.   The purpose of an elected government is to balance the often competing goals on the basis of what it appears society wants.

An extreme example of how the single-minded focus on productivity is dangerous:   As a caring social planner, who believes that society only cares about productivity, I walk into each firm across the country and ask who the least productive employee is.   Then I shoot them.   From there our nation’s productivity increases.   I think we would all agree that such a situation is probably not in the social interest, but it would be supported by a single-mined focus on productivity.

The example does not have to be this extreme for the trade-off to make sense.   If we are focused on productivity we can achieve this goal by lowering employment, or forcing individuals to save at a higher level than they really wish to.   These aren’t satisfactory policy prescriptions, but they can be logically supported by blind support of productivity targets.

When the current government is discussing increasing national productivity there are three ways this could occur through policy:

The first case does not seem to explain the National governments push for productivity, as they aren’t picking up wasteful policies and throwing them away.   Although the push to streamline government activities is laudable and the marginal changes to the Resource Management Act may be worthwhile, neither policy will provide any noticeable boost to activity.  And more importantly both these changes will cost us something in return.

As the second potential reason is obviously false, this leaves us with only the final point:   that the government believes society is willing to accept a little less "redistribution and equality of outcomes" in order to increase the size of the economic pie.

If the government truly believes that society is willing to accept the potential costs associated with lower social spending, different laws, and a smaller government in order to reap the benefits of greater economic activity then why don’t they just say this directly?  

I fear that the government is not directly stating this trade-off because they have talked themselves into believing that it does not exist. In such a situation this is likely to lead to some of the costs of policy being unintentionally underweighted or ignored while the drive for productivity is underway.

Labour got themselves into the same tangle with their unfounded belief that increasing equality did not lead to are duction in economic activity.   We now know that much of the growth they watched over happened in spite of their egalitarian program – not because of it.

Both political parties are unwilling to face that, with respect to government policies, there is a fundamental trade-off between some social values (fairness, justice, etc) and the level of productive activity.   This trade-off is one of the primary reasons for the existence of government – and yet neither of the political parties seem willing or able to recognise it.

As a result, next time we hear the government discuss the importance of productivity, or we hear some international body talk about the goal of productivity growth, let’s try not to forget that there is a trade-off – and let’s ask exactly what this trade-off is.
