, These effects are provided by the linkage between the income distributed by firms and the demand they face (see 3.4.) 2. Both approaches (objectivist and subjectivist) are detailed in Bonanno, 1990.

, The fix-price IS=LM model

, For instance, leisure must not enter into the utility function

, The technology is standard when the production function fulfills Inada's conditions

, The explanations given in the literature are only 'technical' explanations such as: '... such a sufficient condition is satisfied if, for a given per capita endowment of the nonproduced good, the per capita endowment of labour time is large enough, pp.903-907, 1990.

, At a symmetric equilibrium, each firm produces the same amount of output. When cost functions are increasing, convex and identical among firms, the symmetry of the equilibrium is ensured

, These authors call this market structure 'Cournotian monopolistic competition

, In fact, past prices are still present in the expectation function. However they are omitted in the presentation we give because the key variable of our analysis is the current price elasticity of the expectation function
