本文探讨了在资本的波动性调整期间，替代和创新在形成投资和生产率方面的作用。为此，我们使用了丰富的西班牙制造业数据，结合信息设备投资和公司的战略公司层面的面板。投资集中于高投资或投资高峰时期，但其性质取决于可观察到的异质性。我们发现的替代活动的证据，既不涉及工艺创新，也不涉及工厂扩张的公司。然后，我们探讨了在不同的创新战略下，大的投资事件如何传递到生产率的演变。我们发现，在创新企业的投资激增后，生产率提高。然而，长期的学习曲线似乎与创新投资有关。
This paper explores the role of replacement and innovation in shaping investment and productivity during episodes of lumpy adjustment in capital. To this purpose we use a rich firm-level panel of Spanish manufacturing data that combines information on equipment investment and firm's strategies. Investment concentrates on episodes of high investment, or investment spikes, but its nature depends upon observable heterogeneity. We find evidence of replacement activity for firms involved in neither process innovation nor plant expansion. Then, we explore how large investment episodes transmit into the evolution of productivity under different innovative strategies. We find that productivity increases after an investment spike in innovative firms. However, long learning curves seem to be associated with innovative investments.
