Irreversible Capital and the Stock Market Response to Shocks in Profitability
构建了一个资本积累的年份模型，揭示投入或产出价格冲击与企业股票市场价值之间的结构性联系，并发现1973-74年石油危机对资本老旧的企业冲击最大。
This paper develops a vintage model of capital accumulation to identify the structural linkage between shocks to input or output prices and a firm's stock-market value. The model accounts for a substantial part of the sample variation in excess returns, thus providing evidence for a systematic link between the stock-market valuation of firms and the economic factors that affect their profitability. The 1973-74 oil shock is shown to have had a strong impact on excess returns; firms whose capital consisted of vintages built when energy was relatively cheap were hit the hardest in value.
