We propose a stochastic control model to study corporate investment with generalized investment frictions, including investment lags and various of adjustment costs. We find that the dominance of the ``good news principle'' or ``bad news principle'' is determined by the joint effect of...

This paper analyzes the effects of changes in government expenditures on both a domestically produced and an imported good in an open economy based on intertemporal optimizing behavior. The dynamic adjustment is characterized in detail and the critical role played by the accumulating capital...

In this paper, I propose a method to disentangle the informational content of the average Tobin’s q by decomposing it into tangible q and intangible q. I argue that this decomposition increases the explanatory power of the q theory of investment by considering the different nature of corporate...

Investment is often irreversible, in that installed capital has little or no value unless used in production. In the presence of ongoing uncertainty, an individual firm's irreversible investment policy optimally alternates short bursts of positive gross investment to periods of inaction, when...

In this study, we investigate an optimal consumption and investment problem of an economic agent who faces a welfare constraint; the agent does not accept her expected utility (continuation value) falls below a certain fixed level regardless of the time and state. This optimization problem...

This paper proposes a model of diversifiable uncertainty, irreversible investment decisions, and endogenous growth. The detailed microeconomic structure of the model makes it possible to study the general equilibrium effects of obstacles to labor mobility. Labor mobility costs reduce private...
