We use short interest as an investor-based measure of over/undervaluation that distinguishes between the misvaluation and Q-theories of mergers. Using this measure, we find that misvaluation is a strong determinant of merger decision making. Firms in the top quintile of short interest are 54%...

This paper studies the relation between firm value and a firm's growth options. We find strong empirical evidence that (average) Tobin's Q increases with firm-level volatility. The significance mainly comes from R&D firms, which have more growth options than non-R&D firms. By decomposing...

This paper distinguishes between value creation through redistribution of physical assets and that from intangible assets. We decompose the market-to-book ratio into fundamental value and unexplained components and find that mergers create wealth when high-value firms primarily acquire physical...

In this paper, we show that Tobin's q and firm diversification are negatively related. This negative relation holds for different diversification measures and when we control for other known determinants of q. We show further that diversified firms have lower q's than equivalent portfolios of...

For the last two decades, non-US firms have lower valuations than similar US firms. We study the evolution of this valuation gap to assess whether financial markets are less integrated after the 2008 global financial crisis (GFC). The valuation gap for firms from developed markets increases by...
