Google is a classic example of the new ‘Internet economics’. The main service it provides – search – is completely free and yet it is an enornmously profitable company and growing fast. Much of what they provide in addition to their search service is also free: Google Docs, Google Maps and Google Scholar. So how do they do it? The first link below is an article considering this issue and the second link gives access to an archived version of In Business giving further detail. The programme is well worth listening to. A key part of the explanation for this new phenomenon relates to the low and falling costs of providing these internet services.

Sir Alan Walters, one of Mrs Thatcher’s key economic advisers, has died at the age of 82. Though he always tried to shun media attention, Sir Alan attracted a considerable amount of it when he clashed publicly with the then Chancellor, Nigel Lawson, over the Exchange Rate Mechanism (ERM). When faced with the choice from Nigel Lawson that either Alan Walters went or he did, Mrs Thatcher famously chose her adviser over her Chancellor. This lent Sir Alan a degree of infamy in economic circles and he is perhaps known best as one of the most influential monetarists of the period. Sir Alan was an early advocate of money supply targeting and always argued that the money supply should not be manipulated for political reasons. His advice was also key in the budget of 1981 which raised taxes in the middle of a recession, something that in this current recession would appear to be unthinkable.

It is something of a media sport in these recessionary times to find ‘economic scapegoats’. One minute the recession is the fault of the banks and their poor lending practices; the next minute it is the fault of the media themselves, who are constantly reporting doom and gloom; the next minute it is the fault of the politicians, who have failed to react quickly enough to the economic uncertainties; the list goes on! However, the one group that is rarely blamed is ‘us’ – the consumers. Given that the state of the economy is the outcome of our collective decisions, it could be said that we have no real right to complain, as our collective lack of confidence could be what has caused much of the current situation. As James Meek puts it in the article below:

What makes the situation peculiar is that the crisis that threatens us also seems to be us; we are simultaneously menaced by the wave, and exist as elements of the wave. After all, that is what an economic crisis is: the sum of all the actions of billions of people around the world, deciding whether to lend or hoard, borrow or save, sell or buy, move or stay, hire or fire, study or look for work, be pessimistic or optimistic.

The Koruna (or crown) was the national currency of Slovakia. This may not be something you knew until you read it just now and you might as well forget the fact straight away. This is because the Koruna ceased to exist at midnight on December 31st 2008 when Slovakia became the 16th member of the eurozone. The official conversion rate between the Koruna and the euro has been advertised extensively in Slovakia and is 30.126. Slovakians now have to get used to a complete change in their notes and coins as euro notes and coins became legal tender on January 1st 2009. So what will be the impact for Slovakia of joining the eurozone?

The current financial crisis had led to Keynesian theory coming back into fashion. Governments all around the world have put in place a significant fiscal and monetary stimulus to try to mitigate the impact of the downturn. But is this really Keynesian policy at work? Keynes argued for permanent and tough controls on the financial sector to allow the government to pursue a policy of full employment. It would be difficult that current policies are therefore pure Keynesian policies, so is there an economic theory vacuum with market economics discredited, but Keynesian economics not really taking its place? The article below looks at how economic theory has changed in recent months and considers whether we need a ‘new’ Keynes.
