This paper presents a price model of the Input-Output variety. This model computes the changes in the production costs and the prices of goods resulting from changes in the prices of primary factors and imports and changes in indirect taxes. It assumes that all such changes are transmitted in...

This paper uses the results of a poll held at Université Laval to illustrate the difficulty in aggregating individual preferences. In this poll, voters were asked to rank four candidates for a position of dean. The paper provides a brief survey of the literature on the theory of social choice,...

The author shows how, under certain conditions, results from the Quebec Input-Output model can be aggregated to obtain familiar components of the National Accounts and to derive income multipliers. These multipliers are also discussed and compared to other types of multipliers.

In this article, we study the convergence of a sequence of strategic equilibria in a model with a hierarchy of leaders and followers and where firms express their strategy in terms of both prices and quantity. In the duopoly case with an homogenous product, such a strategy set leads to...

In this article, we consider an ordered Stackelberg framework. In such a context, leadership is the preferred position. We show, using a linear model, with constant average costs, that the larger the number of a firm's followers is, the larger its profit. However, as the number of firms...

We show in this article the existence of endogenous rationing in a leader-follower duopoly with differentiated products. The duopolists compete in both prices and quantities and each may choose a price-quantity pair within the residual demand it faces in equilibrium. Therefore they are involved...
