We present a rational theory of SEOs that explains a pre-issuance price run-up, a negative announcement effect, and long-run post-issuance underperformance. When SEOs finance investment in a real options framework, expected returns decrease endogenously because growth options are converted into...

Empirical methods in corporate finance for some time focused on the short-term market reaction to corporate announcements. The associated theories rely heavily on market imperfections such as taxes, transaction costs, information issues and contracting problems to obtain short-term market...

We show that corporate investment decisions can explain the conditional dynamics in expected asset returns. Our approach is similar in spirit to <link rid="b2">Berk, Green, and Naik (1999)</link>, but we introduce to the investment problem operating leverage, reversible real options, fixed adjustment costs, and...

We theoretically and empirically investigate firm-level risk dynamics around seasoned equity offerings (SEOs). Empirically, beta increases before SEOs and decreases gradually thereafter. Using real options theory, commitment-to-invest generates a gradual post-issuance beta decline whereas...

Unconditional alphas are biased when conditional beta covaries with the market risk premium (market timing) or volatility (volatility timing). We demonstrate an additional bias (overconditioning) that can occur any time an empiricist estimates risk using information, such as a realized beta,...

Here we survey the theory and applications of a family of methods (correlated electron-ion dynamics, or CEID) that can be applied to a diverse range of problems involving the non-adiabatic exchange of energy between electrons and nuclei. The simplest method, which is a paradigm for the others,...

We propose a discrete-time stochastic volatility model in which regime switching serves three purposes. First, changes in regimes capture low frequency variations, which is their traditional role. Second, they specify intermediate frequency dynamics that are usually assigned to smooth...

Recent research documents that aggregate stock prices are driven by shocks with persistence levels ranging from daily intervals to several decades. Building on these insights, we introduce a parsimonious equilibrium model in which regime-shifts of heterogeneous durations affect the volatility of...

This paper proposes that equilibrium valuation is a powerful method to generate endogenous jumps in asset prices, which provides a structural alternative to traditional reduced-form specifications with exogenous discontinuities. We specify an economy with continuous consumption and dividend...
