Somali pirates have been much in the news recently with their high profile captures of oil tankers and other ships. The impact on shipping in the area is clear and this has disrupted trade in the region, but an unforeseen impact has been on the total worldwide catch of tuna. The Indian Ocean is one of the richest sources of tuna in the world and the pirate activity has led to a fall of around 30% in the total tuna catch.

An ongoing debate in economics for many years has been the extent to which governments should intervene in the economy. The debate has re-emerged in recent months with the global financial crisis as many commentators have arged that had a tighter regulatory system been in place, it could have helped to prevent some of the poorer lending practices of banks internationally. Even the recent G20 meeting (dubbed Bretton Woods II by some analysts) discussed regulatory reform of the international financial system. The two articles below look at this debate about the extent of government intervention from two very different angles. The first is from the perspective of Victorian England and Little Dorritt, while the second (by Peter Mandelson) looks at how globalisation and the financial crisis have informed the debate about state intervention.

Times of economic uncertainty often lead to people seeking what they consider as ‘safe havens’ for their money. Traditionally gold has been one of these safe havens. This financial crisis has been no exception and the price of gold has risen, but there has also been a rapid growth in demand for gold bullion and gold coins and dealers have found themselves besieged by people looking to protect their savings. ATS Bullion, a London gold bullion dealer, has even seen queues: something quite unprecedented for them.
