A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we present a complex networks perspective on interfirm organizational networks by mapping, analyzing and...

This paper studies the market for monopolistically supplied sweepstakes. We derive equilibrium demands for fixed-prize and variable-prize sweepstakes and determine the profit maximizing prize level and payout ratio respectively. It can be profitable to offer each type of sweepstake when there...

This paper examines how information provided by online reviews influences firms’ pricing strategy for repeat purchase products. It is commonly understood that online reviews can reduce consumer uncertainty about product characteristics and, therefore, have the potential to increase product...

This paper concerns the operation of competition in the presence of a high rate of innovation and increasing returns. Given free competition there is likely to exist, in this case, a tendency towards what may be called "dynamic equilibrium", a tendency, that is to say, for the rate of investment...

One of the most basic principles in economics is that competitive pressure promotes efficiency. However, this pressure can also have a dark side because it makes firms reluctant to act on private information that is unpopular with consumers. As a result, firms that possess superior information...

We provide a survey of the main mechanisms of market selection used in economics. We gather them in three theoretical paradigms (rational equilibrium, Simonesque and evolutionary), that we try to reconcile in terms of underlying laws of selection. We show that the three paradigms have been...

This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

This paper centres around the question of ownership of firms and managerial competition and how these affect manager and employees' incentives to invest in human capital. We argue that employee's incentives in human capital investment are affected by both ownership and competition since both...

Does greater product market competition improve external competitiveness and growth? This paper examines this question by using country-and firm-level data for a sample of 39 sub-Saharan African countries over 2000-17, as well as other emerging market economies and developing countries, and...
