Corporate diversification, investment efficiency and the business cycle
Abstract
I document the time-varying investment efficiency of conglomerates compared with singlesegment firms. I find that, during recessions, conglomerates have higher Q-sensitivity of investment than do stand-alone firms, in contrast to the relationship during expansion periods. I also find that conglomerates, with the benefits from internal capital markets, exhibit increased dependence of investment on internal capital during recessionary periods, while stand-alone firms significantly increase cash retention and deviate their investment from its optimal level more severely. I examine the effect of the degree of diversification and find consistent evidence on investment efficiency and deployment of internal capital. I also provide evidence that conglomerates with stronger governance do not improve investment efficiency during recession, which suggests that agency costs cannot fully explain the changes in investment of conglomerates.
