Given that we expect a long phase in which growth is past its worst but well below trend, it is important to think more carefully about the likely sequencing of risk premia and asset returns, and whether it is the trough in growth or in the output gap (or the labour market parallels of a peak in initial jobless claims versus the peak in the unemployment rate) that matters most for different kinds of assets.

鉴于我们期望一个长期的阶段，经济增长是过去最差的，但远低于趋势，重要的是要想更仔细的可能测序的风险溢价和资产回报，以及它是否是谷底增长或在产出缺口（或劳动力市场平行的高峰，首次申请失业救济人数兑高峰期的失业率）最重要的不同种类的资产。
