Welch (2013) critiques recent work in dynamic corporate finance. We offer the contrasting view that there is no logical reason to dismiss entire research methodologies, and that many methods can be useful. We explain why dynamic models and structural estimation are useful research tools, as well...

We estimate a dynamic investment model in which firms finance with equity, cash, or debt. Misvaluation affects equity values, and firms optimally issue and repurchase overvalued and undervalued shares. The funds flowing to and from these activities come from investment, dividends, or net cash....

We derive and test q-theory implications for cross-sectional stock returns. Under constant returns to scale, stock returns equal levered investment returns, which are tied directly to firm characteristics. When we use GMM to match average levered investment returns to average observed stock...

The neoclassical q-theory is a good start to understand the cross section of returns. Under constant return to scale, stock returns equal levered investment returns that are tied directly with characteristics. This equation generates the relations of average returns with book-to-market,...

We examine whether spin-offs or divestitures cause improvements in conglomerate investment efficiency. At issue are endogeneity of these restructuring decisions and correct measurement of investment efficiency. Endogeneity is a problem because the factors that induce firms to spin off or divest...

This paper examines the relative magnitude of financial versus real frictions by looking at how firms react to cash shortfalls. We use a regression discontinuity design in which the discontinuity is the point of violation of underfunding of corporate defined benefit pension plans. We reexamine...

We develop a theoretical model in which disagreement between management and shareholders creates a link between investment and the stock market. We show that the stock price decreases in the level of disagreement. Because management uses the stock price to infer the level of disagreement, the...
