There are industries that tend to remain monopolized, with successive generations of a good being introduced by an incumbent monopolist. This paper investigates the tendency of persistent leadership in durable goods industry. In particular it explores the implications of the durability of a good...

This paper examines the irreversible adoption of a technology whose returns are uncertain, when there is an advantage to being the first adopter, but a network advantage to adopting when others also do so. Two patterns of adoption emerge: sequential, in which the leader aggressively preempts its...

This paper presents non-parametric microeconomic evidence on stores’ price setting behavior and evaluates the findings in light of theories of nominal price rigidity. The main issues include the durability of price quotations, the size, the frequency and the across-store and within-store...

This paper provides a characterisation of the set of dynamic models in which symmetric duopolists have incentives to raise their common cost. The dynamic analysis has two advantages over existing static models. First, it avoids conceptual weaknesses, allowing conjectures to be derived...

The age structure of its population affects an economy in two ways. On the one hand the accumulation of human capital, that is education, implies the sacrifice of current labour which size depends on that of the cohorts in education. Further, since ageing affects the abilities to work and...

This paper develops a generalised model of network competition when consumers vary in their preferences for network size and location, and networks are vertically and horizontally differentiated. The effect of compatibility on the degree of competition between the networks is analysed. Two...

We identify the inefficiencies that arise when negotiation between two parties takes place in the presence of transaction costs. First, for some values of these costs it is efficient to reach an agreement but the unique equilibrium outcome is one in which agreement is never reached. Secondly,...

This survey is part of a project on The Financial Implications of Environmental Legislation. The purpose of it is to see how the problem of credit rationing, according to borrowers' characteristics, has been empirically estimated in some literature. The survey considers first allocation of...

The empirical evidence suggests that there is a significant, negative relationship between inflation and economic growth. Conventional monetary growth models, however, predict a significantly smaller growth effect. This paper proposes a monetary growth model with an explicit credit service...

We explore sequential voting in symmetric two-option environments. We show that the (informative) symmetric equilibria of the simultaneous voting game are also equilibria in any sequential voting structure. In unanimity games, (essentially) the whole set of equilibria is the same in all...
