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 The first link below is an article considering this issue and the second link gives access to an archived version of In Business giving further detail.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.

Reading the first article linked to below, you may be forgiven for thinking that farming has moved into the realms of science fiction. Dairy farming has moved determinedly into the era of technology and now benefits from extensive economies of scale with much higher productivity levels than even a decade ago. Yet 3000 dairy farmers are planning to leave the industry in the next two years and even the largest farms are struggling to make money. The processing sector has become significantly more concentrated and margins are being squeezed ever further by the power of the supermarkets, so has the market become unbalanced with too much power in the hands of supermarkets and processors?
