That somewhat dry conclusion sums up what amounts to a tempest in econometric circles. The fund has been accused of intentionally underestimating the effects of austerity in Greece to make its programs palatable, at least on paper; fund officials have argued that it was its European partners, particularly Germany, who insisted on deeper, faster cuts. The evolving research on multipliers may have helped shift the tone of the debate in countries like Spain and Portugal, where a slower pace of deficit control has been advocated.
