Inflation Uncertainty and Contract Duration
利用美国工会合同的纵向数据，研究发现通胀不确定性会缩短合同期限，而签约成本（以罢工变量和前期合同期限衡量）则会延长合同期限。
This study examines the determinants of the duration of U.S. union contracts using a longitudinal contract data base. Support is found for the hypotheses that (1) inflation uncertainty reduces contract length and that (2) greater contracting costs, as proxied by a strike variable and by previous duration, increase contract length. In addition, contract duration is found to be greater for indexed contracts, to be procyclical, and to have increased over the sample period. Copyright 1989 by MIT Press.
