We study a simple model in which two vertically differentiated firms compete in prices and mass advertising on an initially uninformed market. Consumers differ in their preference for quality. There is an upper bound on prices since consumers cannot spend more on the good than a fixed amount...

The labor market is introduced into the standard vertical differentiation model, linking increasingly the quality of the product and the effort necessary for workers to produce it. Surprisingly, when two firms compete on the product market but are monopolies on the labor market, at equilibrium...

A theoretical model is considered in a monopoly setting, where the production cost of the firm depends on the efforts of employees who may receive a positive part of the capital if the shareholders find profitable to do so. We specify the condition under which at Nash equilibrium the firm...

We analyze the optimal contract between a risk-averse manager and the initial shareholders in a two-period model where the manager.s investment effort, carried out in period 1, and her current effort, carried out in period 2, both impact the second-period profit, so that it may be difficult to...

We propose to study the trade off between two incentive strategies (moni- toring and efficiency wage versus profit sharing), operated by one firm to induce more efforts among employees. We deal first with a normal context where shirkers bear the risk to be fired. We consider second a particular...

The outbreak of the COVID-19 pandemic led to a sharp decline in the market value of the global equity markets. The purpose of this paper is to answer the following question: Do Compliant firms outperform the Non-Compliant during the COVID-19 pandemic? A compliant firm must satisfy the...
