The value of corporate cash holdings has increased significantly in recent decades. On average, $1 of cash is valued at $0.61 in the 1980s, $1.04 in the 1990s, and $1.12 in the 2000s. This increase is predominantly driven by the investment opportunity set and cash-flow volatility, as well as secular trends in product market competition, credit market risk, and within-firm diversification. We document a secular decrease in the speed of adjustment (SOA) in cash holdings, particularly for financially constrained firms with cash deficits, suggesting that capital market frictions can account for the trend in the value of cash holdings.

This paper studies whether board connectedness affects corporate innovation. We find that well-connected boards have a positive effect on innovation activities and quality. The effect is stronger when firms have higher demand for advising or face more severe agency problems. Firms with greater needs for external finance benefit more from board connections with bankers. We show that the positive relation is causal and robust based on a battery of empirical tests including exogenous variation in board connectedness resulting from death and retirement of directors and from a regulatory shock under new exchange listing rules. Evidence indicates that types and relatedness of connections as well as director characteristics contribute to cross-sectional heterogeneity of the positive effect.
