This note extends the concept of a coherent risk measure to make it more consistent with a firm’s capital budgeting perspective. A coherent risk measure defines the risk of a portfolio to be that amount of cash that must be added to the portfolio such that it becomes acceptable to a regulator. As such, a coherent risk measure implicitly assumes that the firm has already made its capital budgeti...

The paper offers a straightforward method for estimating R&D portfolios that maximize shareholders’ utility. R&D portfolios are generally associated with high returns and high risks. As such, an impressive body of literature has highlighted the risks linked with R&D portfolio allocations. Nevertheless, the role of financing strategies in portfolio allocation has been neglected, and this provide...

Budget allocation is a common task carried in our daily life. As it seems to be necessary to perform this task in an ideal manner this paper mainly deals with budget allocation problem. The main key feature of this work is that it uses a mathematical programming technique Data Envelopment Analysis (DEA) for formulating a proper model for capital budget allocation. This formulation is based on t...

In an asset-pricing model calibrated to match the standard asset pricing empirical properties –in particular, the time-variation in the equity premium – we calculate the welfare (value) implications of sub-optimal capital budgeting decisions. Specifically, we calculate that an investment policy that ignores the timevariation in the equity premium, such as would occur with a cost of capital foll...

Equity marginal q is the change in market value of a company’s equity in conjunction with a oneunit unexpected change in its asset base. Hence, it is a profitability index that evaluates a firm’s capital budgeting decisions at the margin. In this paper, we estimate the equity marginal q for real estate-managing public corporations, namely, real estate investment trusts (REITs), in an attempt to...
