Previous papers on time-inconsistent procrastination assume projects are completed once begun. We develop a model in which a person chooses whether and when to complete each stage of a long-term project. In addition to procrastination in starting a project, a naive person might undertake costly...

Within the expected-utility framework, the only explanation for risk aversion is that the utility function for wealth is concave: A person has lower marginal utility for additional wealth when she is wealthy than when she is poor. This paper provides a theorem showing that expected-utility...

In this paper, we generalize the parametric Delta-VaR method from portfolios with normally distributed risk factors to portfolios with elliptically distributed ones. We treat both expected shortfall and the Value-at-Risk of such portfolios. Special attention is given to the particular case of a...

This paper looks at markets characterized by the fact that the demand side is insured. In these markets a consumer purchases a good to compensate consequences of unfavorable events, such as an accident or an illness. Insurance policies in most lines of insurance base indemnity on the insured’s...

Many observers have expressed concerns about the impact of a rise in interest rates upon banks in India. In this paper, we measure the interest rate risk of a sample of major banks in India, using two methodologies. The first consists of estimating the impact upon equity capital of certain...

We consider optimization problems involving convex risk functions. By employing techniques of convex analysis and optimization theory in vector spaces of measurable functions we develop new representation theorems for risk models, and optimality and duality theory for problems involving risk...

This paper develops an unified framework for analyzing the influence of both direct and indirect instruments of monetary control on the money supply process. The resulting formal model is then applied in the empirical evaluation of the effectiveness of credit ceilings in limiting the growth of...

The bank as "general store" is slowly being replaced by the bank as conglomerate. This is because improvements in information technology and market efficiency are changing the way the activities of financial intermediaries are performed. The imperatives of cost minimization and competition have...

Investment decision-making is modeled by means of a Kohonen neural net, where neurons represent firms. This is done in order to model investments in novel fields of economic activity, that according to this model are carried out when firms recognize the emergence of a new technological pattern....
