This paper develops a model of pricing and advertising in a matching environment with capacity constrained sellers …. Sellers' expenditure on directly informative advertising attracts consumers only probabilistically. Consumers who happen to … maximizing advertising levels are derived and their properties analyzed, including the interplay of prices and advertising with …

A simple Ising spin model which can describe the mechanism of advertising in a duopoly market is proposed. In contrast … via standard Monte Carlo simulations that very simple rules and inclusion of an external field - an advertising campaign …

This paper presents a dynamic partial equilibrium model that endogenizes firms' investment decision on innovation: product innovation causes horizontal expansion growth, and process innovation causes vertical expansion growth. Market structure in different markets emerges as a consequence of...

Efforts to simulate turbulence in the financial markets include experiments with the logistic equation: x(t)=kappa x(t-1)[1-x(t-1)], with 0 x(t)1 and 0 = kappa 4. Visual investigation of the logistic equation show the various stability and instability regimes for the various value of the...

In this paper, I analyze recent findings by Coe and Helpman (1995) of trade-related international R&D spillovers. I show generally that randomly created bilateral trade shares also give rise to large estimated international R&D spillovers; often, in fact, to larger estimated spillover effects...

In this paper we investigate the so called foresight bias that may appear in the Monte-Carlo pricing of Bermudan and compound options if the exercise criteria is calculated by the same Monte-Carlo simulation as the exercise values. The standard approach to remove the foresight bias is to use two...

We propose a structural credit risk model for consumer lending using option theory and the concept of the value of the consumer’s reputation. Using Brazilian empirical data and a credit bureau score as proxy for creditworthiness we compare a number of alternative models before suggesting one...
