Pages 100 – 104 discuss ‘A fair go for working mothers’. Those Liberals MPs criticising Abbott for ‘not consulting’ haven’t read his book.

We should remember that Australia already had a paid scheme – the baby bonus – that got means tested by the current government, so Rudd and friends only have themselves to blame. Similarly big business haven’t been paying the Coalition enough attention and, while I’m sympathetic to their position, they too have themselves to blame. This is especially the case for AIG and BCA.

One of the sillier arguments was published this morning in the Australian – either by Michael Stutchbury or David Uren. The basic argument is that a parental levy will raise Australia’s corporate tax rate to the fifth highest in the OECD. The Uren article has a nice graphic showing this.

This argument is misleading. It is true that another levy will add to the overall tax burden. But this analysis makes two assumptions that are incorrect. First it assumes that businesses only pay corporate tax and no other taxes or levies. But that isn’t true, comparing the Australian headline corporate tax rate plus parental levy to OECD headline corporate tax rates is not comparing like with like. Second, it ignores all the other taxes and levies that business already pays. A couple of years ago I worked on the IPA State Business Tax Calculator (the 2009 version online here). This project consisted of analysing the taxes paid by a standardised business in different Australian States. The bottom line is that the business tax burden is greater than the headline rate suggests.

This represents about 18 per cent of the amount of Commonwealth corporate income tax (CIT) paid (i.e. in addition to the reference business paying company tax levied by the federal government, the business pays the state government tax imposed upon it which equals approximately 18 per cent of what is paid to the federal government).

There is an excellent argument for lowering taxes on business – they are far too high. But the argument that the parental levy will push us far up the tax ladder is not correct – we are already high up on the ladder. The parental levy will add to an already high tax burden, not create that tax burden.

It is understandable that the current government wants to differentiate itself from its predecessor. It is not clear that it should do so by out-spending the Howard government. Ironically Howard has a reputation of being somewhat hard-hearted; yet the empirical record is very different. Andrew Norton of the Centre for Independent Studies has shown that Howard government spending on issues such as Health and Education rose faster than under the previous Keating government. He has labelled Howard a conservative social democrat.

All governments like to think that increasing the amount of money thrown at problems will solve that problem. But, as we now know from the Rudd government stimulus package, the quality of spend can be more important than the quantity of spending. So too with health – my IPA colleague Julie Novak has shown that the number of back-office bureaucrats has been increasing, while the number of hospital beds per 1000 population has declined. In the spending we have had over the past fifteen years, the bang for buck has declined.

A German aristocrat of my acquaintance has figured out that the price he will be paid for the output of a solar panel is so high compared with the price he will pay for his input of normal electricity, that he is thinking of rigging up powerful arc lamps to shine on solar panels on his extensive roof.

Today Paul Sheehan has this comment.

The big lie, repeated again and again, is that the Howard government stripped a billion dollars out of the health system. This claim cannot withstand scrutiny. Any government minister who repeats this mantra is lying.

Them’s fighting words. So I had a look at some ABS data I collected last year on government spending and pulled out the Health spend data.

Overall the Commonwealth spent more on Health than did the States. What about acute care institutions (I assume these are hospitals)?

It looks like the States massively increased spending on hospitals after the GST came in – the same GST that the Commonwealth now proposes to cut.

(I haven’t updated my spreadsheet to take into account the latest year of data to become available (2007-08). It is very unlikely that the result would change if I did include that year. In any event most of that year would be the first year of the Rudd government.)

Update: I was wondering where Uhlmann got his stats from. It looks like he was quoting from the Australian Institute of Health and Welfare.

if you can’t get basic stats right, you can’t get economics right either

I’d like to think that’s right, but I know it isn’t. First specialisation and the division of labour suggests that it would/should be possible to get economics right and not stats. Second, Deirdre McCloskey and Stephen Ziliak have tested that hypothesis. From the introduction of their 2003 Journal of Socio-Economics article.

Eight years ago, in “The Standard Error of Regressions,” we showed how significance testing was used during the 1980s in the leading general interest journal of the economics profession, the American Economic Review (McCloskey and Ziliak, 1996). The paper reported results from a 19-item “questionnaire” applied to all of the full-length papers using regression analysis. Of the 182 papers 70% did not distinguish statistical significance from policy or scientific significance—that is, from what we call “economic significance” (Question 16, Table 1, p. 105). And fully 96% misused a statistical test in some (shall we say) significant way or another. Of the 70% that flatly mistook statistical significance for economic significance, further, again about 70% failed to report even the magnitudes of influence between the economic variables they investigated (1996, p. 106). In other words, during the 1980s about one-half of the empirical papers published in the AER did not establish their claims as economically significant.
…
We are very willing to believe that our colleagues have since the 1980s stopped making an elementary error. But like them we are empirical scientists. And so we applied the same 19-item questionnaire of our 1996 paper to all the full-length empirical papers of the next decade of the AER, just finished, the 1990s. Significance testing violating the common sense of first-year statistics and the refined common sense of advanced decision theory, we find here, is not in fact getting better.
…
It is getting worse. Of the 137 relevant papers in the 1990s, 82% mistook statistically significant coefficients for economically significant coefficients (as against70%in the earlier decade). In the 1980s, 53% had relied exclusively on statistical significance as a criterion of importance at its first use; in the 1990s 64% did.

In their conclusion, this sentence sums it up.

The situation is strange: economic scientists, for example those who submit to and publish papers in the AER, or serve on hiring committees, routinely violate elementary standards of statistical cogency.

Does this make the AER authors bad economists? Not according to McCloskey and Ziliak.

The American Economic Review is filled with examples of superb economic science (in our opinion most of the papers can be described this way—even though most them, we have seen, make elementary mistakes in the use of statistical significance; in other words, we do not accept the opinion of one eminent econometrician we consulted, who dismissed our case by remarking cynically that after all such idiocy is to be expected in the AER).

Ziliak and McCloskey discuss this issue in book length too.

A higher minimum wage has the biggest impact on those with the least experience or the fewest skills. That means in particular those looking for entry-level jobs, especially teenagers. And sure enough, as nearly all economic models predict, the higher minimum has wreaked havoc with teenage job seekers, well beyond what you would expect even in a recession.

They provide a graph to illustrate their argument, but this graph from MJ Perry is even better.
