Many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty. Motivated by experimental evidence such ast he Ellsberg Paradox, we follow Knight (1921) and distinguish risk from uncertainty. To capture this distinction, we adopt the multiple-priors...

This paper embeds an oligopolistic industry structure in a real options framework in which synergy gains of horizontal mergers a rise endogenouslya nd vary stochastically over time. We find that(i) mergers are more likely in more concentrated industries; (ii) mergers are more likely inindustries...

Entrepreneurs often face undiversi¯able idiosyncratic risks from their business invest- ments. Motivated by this observation, we extend the standard real options approach to investment to an incomplete markets environment and analyze the joint decisions of busi- ness investments,...

Entrepreneurs face significant non-diversifiable business risks. We build a dynamic incompletemarkets model of entrepreneurial firms to demonstrate the important implications of nondiversifiable risks for entrepreneurs’ interdependent consumption, portfolio allocation, financing, investment,...

We develop a dynamic general equilibrium model to study the impact of the 2003 dividend and capital gains tax cuts. Firms are heterogeneous in productivity and make investment and financing decisions subject to capital adjustment costs, equity issuance costs, and collateral constraints. Our...

This paper studies the interaction between product market competition and takeover activity. We develop a dynamic model in which profit-maximizing production decisions of all firms in an industry as well as the timing and terms of a merger between two firms are jointly determined. We show that...

Many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty. Motivated by experimental evidence such as the Ellsberg Paradox, we follow Knight (1921) and distinguish risk from uncertainty. To afford this distinction, we adopt the multiple-priors...

This paper develops a continuous time real options model to study the interaction between industry structure and takeover activity. In an asymmetric industry equilibrium, firms have an endogenous incentive to merge when restructuring decisions are motivated by operating and strategic benefits....

Entrepreneurs face significant non-diversifiable business risks. We build a dynamic incompletemarkets model of entrepreneurial finance to demonstrate the important implications of nondiversifiable risks for entrepreneurs’ interdependent consumption, portfolio allocation, financing, investment,...

To study the long-run effect of dividend taxation on aggregate capital accumulation, we build a dynamic general equilibrium model in which there is a continuum of firms subject to idiosyncratic productivity shocks. We find that a dividend tax cut raises aggregate productivity by reducing the...
