We develop a general equilibrium model of a production economy which has a risky production technology as well as a growth option to expand the scale of the productive sector of the economy. We show that when confronted with growth options, the representative consumer may sharply alter...

This paper introduces a new method of investment performance analysis, based on the recent approach of Average Internal Rate of Return (AIRR). We show that the approach generates rates of return suitable for assessing both a fund´s (portfolio´s) performance and a manager´s performance. The...

This teaching note shows the relationship between levered and unlevered betas and the general formulation for the cost of equity. It also shows, step by step, the procedure to estimate betas from data found in the stock market.It shows well known procedures for estimating betas: correlation...

In investment appraisal, uncertainty can be managed through intervals or fuzzy numbers because the arithmetical properties and the extension principle are well established and can be successfully applied in a rigorous way. We apply interval and fuzzy numbers to the Average Internal Rate of...

We introduce Indirect Robust Generalized Method of Moments (IRGMM), a new simulation-based estimation methodology, to model short-term interest rate processes. The primary advantage of IRGMM relative to classical estimators of the continuous-time short-rate diffusion processes is that it...

The classic Lucas asset pricing model with complete markets stresses aggregate risk and, hence, fails to investigate the impact of agents heterogeneity on the dynamics of the equilibrium quantities and measures of trading volume. In this paper, we investigate under what conditions...

This paper develops a continuous-time model of liquidity provision by banks, in which customers can deposit and withdraw their funds strategically. The strategic withdrawal option introduces an incentive-compatibility problem that turns the problem of designing deposit contracts into a...
