A monopolist is treated as a nexus of contracts with team production. It has one ownermanager. The owner-manager is the employer of two employees. A team production problem is present if the employer is a “managerial lemon”. If the team production problem is solved, the employer is a...

Innovation is an important topic in economics. This paper highlights duopoly innovation under the Hotelling model with game theory approaches. This paper argues that market power, as measured by the cost advantage of a dominant firm over its rival, serves to enhance the incentive to innovate in...

Firms' quality commitment can efficiently improve the demand. This paper addresses the quality commitment under the duopoly. By establishing a Cournot model, the effects of quality commitment are discussed. Firstly, under one-sided quality commitment, the higher efficiency firm committing in...

We describe the competitive environment of microcredit markets globally and we study the effects of competition on loan rates of microfinance institutions (MFIs). We use a new database from rating agencies, covering 379 for-profit and nonprofit MFIs in 67 countries over 2002-2008. First, we find...

Since the 1980s, important and progressive reforms have profoundly reshaped the structure of the Chinese banking system. Many empirical studies suggest that financial reform promoted bank competition in most mature and emerging economies. However, some earlier studies that adopted conventional...

We investigate the relation between a Cournot equilibrium and a Bertrand equilibrium in a duopoly with differentiated substitutable goods in which each firm maximizes its relative profit that is the difference between its profit and the profit of the rival firm. We show that when firms maximize...

After some decades of relative oblivion, the interest in the optimality properties of monopolistic competition has recently re-emerged due to the availability of an appropriate and parsimonious framework to deal with firm heterogeneity. Within this framework we show that non-separable utility,...

This paper aims at modeling Afore’s strategies which are addressed to retain the largest number of pensioners with different income levels in a cost competition setting. In doing so, we simulate a non-cooperative static two stages game to model competition between M = 1 leaders and N followers...

This paper compares the equilibrium outcomes under simultaneous and sequential price settings in a vertically differentiated market. When the timing of the price game is determined endogenously, it is shown that the sequential play with the high quality firm leading emerges, yielding the highest...
