We examine the asset pricing implications of a neoclassical model of repeated investment and disinvestment. Prior research has emphasized a negative relation between productivity and equity risk that results from operating leverage when capital adjustment is costly. In general, however,...

Investment-based asset pricing research highlights the role of irreversibility as a determinant of firms' risk and expected return. In a neoclassical model of a firm with costly scale adjustment options, we show that the effect of scale flexibility (i.e., contraction and expansion options) is to...

A large body of literature demonstrates that acquisitions are on average value-destroying for the acquirer. We investigate whether the change in the acquirer's information uncertainty contributes to acquirer wealth losses. Information uncertainty affects the discount rate (the cost of capital),...

Especially with the evaluation of non-listed (medium-sized) companies, the following problems and significant restrictions pertaining to the applicability of the CAPM must be taken into account when determining cost of capital. 1. Homogeneity of expectations and planning consistency. Given the...

This paper examines the effects of liquidity on stock and portfolio risk measures by analyzing Value at Risk (VaR). Using daily stock returns and firm market capitalization, empirical calculations confirmed that VaR has not yet succeeded to prove patterns of relation between risk and liquidity,...

While discussing risk issues someone told me as a joke that she wished the world were riskless and the fact that risk were present in any instance in our lives was a rather unfortunate circumstance. But would we be really better off in a riskless world?Although it may appear to be a trivial...

The properties of information, including "information uncertainty", can be understood only Bayesianly. Common formulations that define information uncertainty in terms of just statistical "precision" (i.e. sampling variance), or any one estimator characteristic (e.g. bias), are inadequate for...

The real options tradition originally predicted a decreasing relationship between uncertainty and investment, through the positive effect of higher uncertainty on the trigger level for revenue relative to costs. An opposing effect on the probability of reaching the level has been identified,...

This paper presents a tractable model of a firm that chooses both the scale and timing of its investment. The value-maximizing investment policy is lumpy, and sensitivity analysis shows that greater demand volatility is associated with the firm choosing to invest in larger increments, less...

Many economic variables of interest exhibit a tendency to revert to predictable long-run levels. However, mean reverting processes are rarely used in investment models in the literature. In most models, geometric Brownian motion processes are used for tractability. In this paper, a firm's entry...
