We develop and analyze a model of a multi-stage investment project that captures many features of R\&D ventures and start-up companies. An important feature these problems share is that the firm learns about the potential profitability of the project t

As a consequence of optimal investment choices, a firm's assets and growth options change in predictable ways. Using a dynamic model, we show that this imparts predictability to changes in a firm's systematic risk, and its expected return. Simulations show that the model simultaneously...

I model strategic interaction among issuers, underwriters, retail investors, and institutional investors when the secondary market has limited price transparency. Search costs for retail investors lead to price dispersion in the secondary market, while the price for institutional investors is...

We develop a simple rational model of active portfolio management that provides a natural benchmark against which to evaluate observed relationship between returns and fund flows. Many effects widely regarded as anomalous are consistent with this simple explanation. In the model, investments...

Municipal bonds trade in opaque, decentralized broker-dealer markets in which price information is costly to gather. Whether dealers in such a market operate competitively is an empirical issue, but a difficult one to study. Data in such markets is generally not centrally recorded. We analyze a...

We develop and analyze a model of a multi-stage investment project that captures many features of R&D ventures and start-up companies. An important feature these problems share is that the firm learns about the potential profitability of the project throughout its life, but that research and...

As a consequence of optimal investment choices, firms' assets and growth options change in predictable ways. Using a dynamic model, we show that this imparts predictability to changes in a firm's systematic risk, and its expected return. Simulations show that the model simultaneously reproduces:...
