Many derivatives prices and their Greeks are closed-form expressions in the Black-Scholes model; when the terminal distribution is a mixed lognormal, prices and Greeks for these derivatives are then a weighted average of these closed-form) expressions. They can therefore be calculated easily and...

The attempt to match characteristics of asset pricing models such as the risk-free interest rate, equity premium and the Sharpe ratio for models with instantaneous consumption decisions in the context of stochastic growth models has not been very successful. Many recent versions of asset pricing...

The purpose of this paper is to analyze how heterogeneous behaviors of agents influence the exchange rates dynamic in the short and long terms. We examine how agents use the information and which kind of information, in order to take theirs decisions to form an expectation of the exchange rate....

Combining two or more items and selling them as one good, a practice called bundling, can be a very effective strategy for reducing the costs of producing, marketing, and selling goods. In this paper, we design a system for a shop, to negotiate both the contents and the price of bundles of goods...

Modularity has recently become an important concept in economics and management science alike (Ulrich 1995; Baldwin and Clark 2000). However, it is not always clear what is meant by modularity as formal treatments are rare. The aim of this paper is threefold. First, we want to provide a rigorous...

The paper analyses the role of capital structure of firm on industry dynamics. Empirical evidence shows that policy interventions can alter for some the frims�cost of the capital. As a result firms on average are overcapitalized with a low capital productivity. Moreover, the market in which...

The paper considers the application of Genetic Algorithms (GA) on coordination games with non-point pollution controlling systems including collective and random fines. During the GA simulations populations continually switch between the two symmetric Nash equilibria of the game. Coordination of...

Network economics holds the view that individual actions and, in turn aggregate outcomes, are mainly determined by the interaction structure between heterogeneous economic agents. In this paper we study the diffusion of an innovation over a social network. More specifically, we study whether...

On the one hand, recently a number of theoretical models have highlighted the role of credit market frictions in propagating and amplifying macroeconomic shocks. On the other hand, it still seems an open question whether this role is quantitatively significant. Our paper tries to fill this gap....

Qualitative properties of optimal investment strategies for a firm with quadratic costs and non-concave revenues are analysed. Organising information in a bifurcation diagram, it is found that the organising centre of the diagram is a so-called swallow-tail singularity. This implies the...
