In this study, we trace the impact of corporate focus by estimating the relationships of focus with cash flow and firm value. In contrast to past studies that examine the effects of diversifying across SIC code defined industries, we show, using Tobin's q, that diversification even within a...

This paper studies expectations of capital appreciation in the housing market. We show that expectations impounded in the rent/price ratio at the beginning of the decade successfully predict appreciation rates, but only if we first control for cross-sectional differences in the quality of rental...
