Quote from listedguru: I'm glad his arguments are so weak and flawed (just like the tax itself)...
Yes, one has to admire this man's intellectual honesty (ironically, no irony there). But playing an objective scientist, hijacked by the populists is probably the most effective technique after all - it is the fair prosecutor that defense lawyers fear most...
So what Mr. Baker has just admitted here?
1) FTT taxes have not been designed to raise revenue, but for behavior modification purposes: "An FTT will raise transactions costs and therefore reduce the volume of trading. This is one of the main purposes of the tax."
2) Some short-term transactions are non-speculative and beneficial for market stability (i.e. taxing them would increase volatility): "Some of transactions that will be discouraged by an FTT will be stabilizing. For example, arbitragers trade to take advantage of small differences in prices between different markets."
3) There is no empirical evidence that the FTT taxes work, i.e. fulfill their primary purpose of reducing "long term overshooting" or "excessive volatility": "higher transactions costs are associated with higher volatility .. no significant effect on volatility". He even resisted from quoting the only empirical paper that shows that higher transaction costs can decrease statistical volatility (probably because the paper does so "contrary to previous studies..")
4) The custom definion of volatility in the Tobin tax theory ("long term overshooting") is non-falsifiable: "difficult to test, since unambiguous examples of speculative price movements are relatively rare."
5) Short-term liquidity-providing traders are beneficial for the investing public: "Trading costs have fallen sharply over the last three decades due to improvements in computer technology."
6) Tax rates proposed by the DeFazio bill would set us back 3 decades: "Therefore, even with FTTs in place, transaction costs would only be rising to their level of two decades ago in most markets [..] would only raise levels of volatility back to their 1980s level [..] already had vibrant capital markets in the 80s" (2010..1980 is 30 or even 31, not 20, but never mind the details
7) The largest investors (i.e. pension funds and other closet indexers) would lose most, because the most liquid stocks would be most affected: "This means that the greatest reduction in trading volume will occur in assets that have the most liquid markets, leaving them still quite liquid. The impact of the tax on trading volumes in markets that are already not very liquid will be considerably smaller."
8) Transaction taxes can create permanent inefficiencies and delay the process of price adjustment to new information even by several days: "lower trading volume could in fact lead to less efficiency [..] whether prices adjust in a single day or over a couple of days. It is difficult to imagine that this sort of delay in price adjustment would have any major repercussions for investment and real economic activity."
9) Middle class investors are not allowed to make a fortune on the stock market (they should lie back and think of England

: "Their goal is to save for specific purposes such as retirement or their childrenâs education, not make a fortune by constantly flipping stock or other assets"
10) There is a negative feedback loop linking FTT with its tax base, which will make it difficult to raise much revenue: "but they are likely to respond to the tax by cutting back substantially on the frequency of their trades."
11) Trading volumes would decline sharply: "the calculations of the revenue raised through a tax assume sharp reductions in trading volume [..] assuming that trading volume falls by 50 percent." Here's a novelty, because Baker (2000) clearly assumed only 1/3 volume reductions (and a tax rate for stocks of 0.5%). So where can we see the details of the new calculation? And why we cannot use the older one? Has anything changed in the models used?
Other of his arguments are a bit less intellectually honest though, but we have already discussed them ad nauseam, so let's not engage in too much Baker-bashing again - he did admit enough already. Some of the areas where he has been economical with the truth, already discussed by us earlier, are:
- "tax-sheltered accounts would be exempted from the tax as would trades by pension funds [..] unlikely that middle class investors will pay the tax." (how about wider bid/ask spreads - any exemptions there?)
- "large traders will pay the tax" (incl. market makers?)
- "the tax is constructed to cover the whole array of tradable assets" (incl. forex and bonds?)
- "the U.K. raises the equivalent (relative to its GDP) of more than $30 billion a year on a tax that is only applied to stock trades" (this may be true, but volume, not GDP differences have been used in the literature and the UK tax rate of 0.5% must not be assumed, so it is overestimated about 3 times),
- "While there will be some efforts to shift the location of trading to evade the tax, it is likely that the impact of such shifting on the revenue collected will be relatively limited" (only if you did it at the full G20 level - see Sweden)
- "There seems little doubt that if the United States pushed for such taxes at the G-20 or other international forums that it could count on considerable cooperation from other countries" (like the countries which abolished the tax: India, Australia, Sweden, Japan, Germany...)
- "effective enforcement of financial transactions taxes requires only the policing of a relatively small number of very large transactions." (trading volume is quite different: mostly composed of a large nubmer of relatively small transactions, due to the use of the anti-price-impact order-splitting algos by the funds).
There are plenty of valid criticisms Mr. Baker chose not to respond to, by which he probably meant: "I'll pass on that".
All in all, I'm impressed by Mr. Baker's honesty, but not as much as with that Austrian paper I once dissected for the Wiki page - that one was so self-accusatory that tax proponents' mercenary, Boyd Reimer had to put more than a dozen of "some" qualifiers just to distance himself from those views (see the "Tobin tax proponents view on volatility"):
"Unfortunately, all empirical studies on the relationship between transaction costs, trading volume and price volatility in general, and on the possible effects of an FTT on volatility in particular, deal with short-term statistical volatility only. Therefore, the results of these studies cannot help to answer the question whether or not an FTT will mitigate misalignments of asset prices over the medium and long run." (Schulmeister et al, 2008, p. 11)
Such a pity that these Austrian guys have been caught on the wrong side of the argument... because their blind followers / idea hijackers / free-riders such as the union-funded think-tanks, Halifax Initiative or the 'direct-debit charities' are nowhere near their levels of intellectual honesty...
