Key signs point to a pickup in private equity (PE) activity in 2014 and optimism is running strong, according to a survey of 100 PE firms and 1,600 corporations by EY and the Economist Intelligence Unit. Some reasons for the optimism: The world economy is forecast to grow faster — by about a half of a percentage point over 2013, many economic forecasters say; there is plenty of cash available for deals; and the number of mergers and acquisitions – which often stoke PE activity — is expected to rise. What’s more, investor interest in BRICS countries and emerging markets also is increasing.
