Tall tales of taxing talent

Matt’s post on equity and efficiency reminds me of a paper by Greg Mankiw and Matthew Weinzierl on optimal taxation. The idea is as follows. Suppose that we think equity means a society where everyone has the opportunity to earn income proportional to the effort that they exert. The hardest workers are those who succeed in earning the most money, while others may choose a life of leisure and earn less. Well, to establish such a utopian place we’d have to do a lot more than eliminate racism, sexism and xenophobia from the human race. Read more

Labour market shortages and mobility

Kiwiblogblog raised the issue of labour shortages in New Zealand. As well as mentioning the labour shortages in New Zealand, they also stated that similar labour shortages exist overseas. Some of these shortages (eg doctors) have existed for a long time, all around the world. However, if this is the case why isn’t the wage rising to try and take care of these shortages?

High Wages and Productivity: Where are the emperor’s Clothes??

So there is a big debate raging in the New Zealand blogosphere about the exodus of labor to Australia. Matt
joined in on the debate and made the very valid point that it’s real wages we need to care about, not the nominal wage and that for this happen we basically need productivity increase so that output increases. The same people with more money buying the same set of goods will just push prices up leaving us where we started.

While I don’t want to wade heavily into the debate, I’m still undecided what the best course to take is as I’m not totally convinced by the arguments from the left or the right. The one thing that does bother me is that strengthening employee power to negotiate higher wages seams to be though of as a magic wand. In line with Matt’s argument, giving workers higher wages doesn’t really do much if there isn’t a corresponding increase in productivity. People seem to have the causality all wrong, in general increases in productivity increase wages not the other way round.

Migrant outflows to Australia, wages, and productivity: What is going on?

A rising outflow of New Zealander’s to Australia is causing concern amongst a bunch of people. People move away for a number of reasons, as the Department of Labour nicely points out. However, as economists we like to think at the margin. We are not interested in the general reasons that people are leaving New Zealand, in so much as we are interested in the ‘marginal’ factors that are driving people overseas. The non-policy factors mentioned by DOL are constant, the weather will stay warmer, the country will remain as close, and the culture will remain similar. However, the policy factors (e.g wages, taxes) can be changed, and as a result will have an impact on the ‘change’ in migration levels (beyond some sort of trend).

The Standard provides one piece of the puzzle we require in order to control migrant outflows – we need higher wages. However, the solutions they provide may not necessarily be the correct ones. A important marginal factor in the decision on whether to stay and work in NZ, or do so in Australia is the difference in ‘real disposable income’. Ignoring non-wage income for now leaves us with ‘real disposable salary’. Increasing nominal wages may not lead to an increase in real disposable salary if all it does is increase inflation. If we pay everyone more $$$ but don’t increase the number of goods avaliable to buy, then the price of goods will increase and peoples true living standard will not change.

Interest free student loans and compulsory schooling: Is there a better way?

Recently the two main political parties in New Zealand have announced schemes that aim to, in some ways, help up-skill 16 and 17 years olds. At the same time, National has come out stating that it will leave student loans interest free, but provide a reward for repayments (leading to much debate).

Although these may seem like separate issues, when I look at the economy the issues of youth employment/skills, education, and unemployment/employment are intensely linked. As a result any policy that the parties take up on one of these issues must take into account how it influences these other sections of society.

In this post my aim is to put forward my current belief of what an ideal policy would look like for these three sectors – that’s right, I said policy not policies. Personally I think that all three are so closely linked that we have to use the same or very similar instruments in order to provide the right sort of outcome. Now, this analysis will be unashamedly normative, I’m going to be packing it with value judgments. I will try to make these judgments clear so you can either i) attack me on them, ii) work out where my objective logic may have gone wrong, separate of the value judgments.

Rational repression

Perhaps it is apropos to start the new year’s blogging with a look back at history. A working paper reported at Vox examines Stalin’s gulags from an economic, rather than political, viewpoint. In Western capitalist economies it is the threat of losing one’s job that motivates effort in employment. If you shirk and are caught then you get fired. However, in a centrally planned economy there is no possibility of getting fired: everyone has a role to play and nobody is left out. How then is a dictator who’s done the hard yards planning out the lives of an entire country for five years to motivate his workforce? Miller and Smith suggest that Stalin used the gulags as a device to enforce discipline among workers. Read more
