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,...

From a CAPM-type model the cost of equity is derived for a firm operating under various foreign tax systems. The firm’s shares are traded in a market which is unaffected by these systems. The cost of capital depends on the foreign tax system, even for fully equity financed projects. This is...

We discuss the prevalence of pooling equilibria in a two-period model of an insurance market with asymmetric information. We solve the model numerically. In addition to reporting cases where a pooling equilibrium exists, we pay attention to why, in the case of non-existence of a pooling...

Lund (2002a) showed in a CAPM-type model how tax depreciation schedules affect required expected returns after taxes. Even without leverage higher tax rates implied lower betas when tax deductions were risk free. Here they are risky, and marginal investment is taxed together with inframarginal...

Even for fully equity-financed firms there may be substantial effects of taxation on the after-tax cost of capital. Among the few studies of these effects, even fewer identify all effects correctly. When marginal investment is taxed together with inframarginal, marginal beta differs from average...
