Black becomes white in Sweden

Two years after being elected, the Swedish coalition government is planning a raft of tax reforms. There are to be reductions all round and “black” work is to become legal. Sweden spends a lot on public services, over 50% of GNP being in the public sector. If it is going to improve its defences as well, it is going to have to spend a lot more. So how is this going to work?

Presumably somebody has been reading Laffer, who devised the famous Laffer curve which shows that tax yields reach a maximum at a certain rate of tax and decline if tax rates are higher. There is some truth in the argument; it would be expected on theoretical grounds, as most taxes give rise to a deadweight loss, consisting of production that would take place were it not for the tax. The effect takes place at the margin, in that taxation at locations close to the margin has the effect of knocking enterprises at those sites out of production by rendering them unprofitable. For this reason there should be a further benefit from tax cuts in that unemployment ought to come down and with it the costs of paying out benefits. The trouble with Laffer is that the theory is simplistic. It ignores the simple and obvious fact that the effects of taxes depend on what is taxed. Taxes on windows lead to bricked-up windows. Taxes on alcohol and tobacco lead to less smoking and drinking. Taxes on work lead to idleness. A tax on the rental value of land leads to – what?

It may be that lower rates of taxes in Sweden will increase the yield but time will tell. But what will certainly fail is the plan to make “black” work “white”. Of course it is wrong to tax people’s labour. But the tax system can be compared to a net. If holes are cut in it, for instance, by making concessions, this gives people opportunities for legal tax avoidance, and they will take advantage of them.

The only way round this is to phase out taxes on labour, goods and services altogether, and to replace these with a tax on the rental value of land. The yield from such a tax is buoyant and avoidance and evasion are impossible. As long as the timetable for the change is realistic and the land value tax is not an additional tax, the flow of revenue is sustained and business flourishes.

Importing people to sustain demand

I got involved in a discussion with a Youtuber called “Philosophy all along”. This was in connection with criticism of Trump’s policy of deporting illegal migrants, which he argued would be bad for the economy as it would reduce demand. This implies that there is a need to import people to sustain demand. There is no obvious reason why a population should not be able to consume everything that the same population produces. If it can not, then something else is going on. It is a basic principle that wages are the least that workers will accept to do a job. Wages are a share of the value added by workers through their wages. The remainder is distributed as economic rent, after government has taken its cut in taxes. Monopoly profit is a temporary surplus that after a delay gets absorbed into economic rent. Land values in Silicon Valley are an example of this; it's like a gold rush. The miners get little out of it. Rent and tax syphon purchasing power away from those who produce the g...

The Zombie Train that refuses to die

The Guardian has published a couple more articles against HS2, one by specialist rail commentator Christian Wolmar, and another today by journalist Simon Jenkins. The main arguments in favour will doubtless be wheeled out by the commentators: the need for capacity and the disruption caused by upgrading existing routes. HST itself will severely disrupt services to Euston during the construction period. Capacity can be increased at a fraction of the cost by a variety of measures, provided that it is accepted that the additional traffic will run at existing speeds. It is not generally known that the Midland main line is, or was, four track all the way from London to Trent Junction, between Nottingham and Derby. This is because the additional tracks are separate, having been added for coal trains which trundled down to Brent sidings, on the edge of London, from a collection point at Toton in Nottinghamshire, where the Midland Railway build a huge marshalling yard. Beyond Derby, the main l...

How much more will the British tolerate?

The British are phlegmatic, tolerant and slow to rouse. Thus there was no great reaction after the terrorist attack in July 2005. The murder of Lee Rigby created a sense of outrage, but nothing more, since it appeared to be an isolated incident. Two serious incidents within a fortnight are another matter. Since the first major terrorist incident in 2001, authority has tried to persuade the public that Islam is a religion of peace, that these were isolated events, or the actions of deranged "lone wolves", having nothing to do with Islam, or to reassure that the chances of being killed in a terrorist attack were infinitesimally small. These assurances are are beginning to wear thin. They no longer convince. If government does not act effectively, people will take the law into their own hands. What, however, would effective action look like? What sort of effective action would not amount to rough justice for a lot of innocent people? Given the difficulties of keeping large n...
