This paper introduces the concept of Conjectural Link for Complex Networks, in particular, social networks. Conjectural Link we understand as an implicit link, not available in the network, but supposed to be present, based on the characteristics of its topology. It is possible, for example, when in the formal description of the network some connections are skipped due to errors, deliberately h...

Abstract. The aim of this paper is to present evidence for a simple conjectural relation between eigenvalues and invariant factors of incidence matrices associated with adjacent ranks in differential posets. The conjectural relation yields the Smith invariants immediately, as the eigenvalues are completely understood [3, 15]. Furthermore, we consider more general structures: dual graded graphs ...

This paper analyzes the influence of the East Asian crisis and the subsequent reforms on the oligopolistic nature of the Thai banking industry. Since the crisis, there have been substantial changes in competitive environment, including a decline in the family ownership of banks as well as the arrival of new entrants. How did these changes affect a banking industry in which the six largest local...

This paper presents a conjectural-variation-based equilibrium model of a single-price electricity market. The main characteristic of the model is that the market equilibrium equations incorporate the effect of the voltage constraints on the companies’ strategic behavior. A two-stage optimization model is used to solve the market equilibrium. In the first stage, an equivalent optimization proble...

This paper develops and estimates a structural model of imperfect competition in international markets. The model incorporates a flexible non-linear demand framework with structural price equations, and a general Conjectural Variation approach is developed to characterize strategic interaction. The model is used to evaluate the effects of the signature by a small open economy, Lebanon, of a Pre...

Suppose that in symmetric aggregative games, in which payoffs depend only on a player’s strategy and on an aggregate of all players’ strategies, players have conjectures about the reaction of the aggregate to marginal changes in their strategy. The players play a conjectural variation equilibrium, which determines their fitness payoffs. The paper shows that only consistent conjectures can be ev...
