西切尔使用国家经济研究局的商业周期年表估计了威布尔风险模型,并发现只有战前扩张和战后收缩存在持续时间依赖的证据。本文更新了战后样本,直到最近一次扩展结束,并使用了一个广义的威布尔模型,该模型以一个额外的参数为代价提供了更大的灵活性。该模型为所有样本找到了持续时间依赖的证据,并且在统计上优于传统的威布尔模型,对除战后宫缩以外的所有样本。
Sichel estimated a Weibull hazard model using the National Bureau of Economic Research business cycle chronology and found evidence of duration dependence only for prewar expansions and postwar contractions. The article updates the postwar sample through the end of the most recent expansion and uses a generalized Weibull model that provides much greater flexibility at the expense of one additional parameter. This model finds evidence of duration dependence for all samples and is statistically superior to the conventional Weibull model for all samples except postwar contractions.
