The prospect of a double-dip recession is the biggest fear of executives, a new study has found. Almost one-third of the 680 executives questioned by the Economist Intelligence Unit, the research and analysis arm of the respected magazine, said that such a relapse was the biggest risk to the world economy in the second half of 2010. A further 20% said sovereign debt default was the biggest risk, while 10% cited weak governance. Iain Scott of the Economist Intelligence Unit said its own global forecast played down the risk of double-dip recession. He added: "We do, however, expect a sustained period of slow growth, exacerbated by the fiscal austerity measures being introduced in many major economies. But if all goes well, we expect that structural reforms, combined with some productive allocation of spending, will boost growth in the long term." Despite economic uncertainty, 86% of executives said they were confident their business could deal with the risks facing them during the second half of the year.
