Les effets de la politique de crédit sur le choix des investissements dans une industrie lourde

The macro-economic impacts of the credit policy on the decisions of the firms are \nown. Through a micro-economic model of linear programming the present study tries to throw some light on the relationship between the choice of investment and the range of loans offered by a bank. The originality of the model in addition to the fact that it covers several periods, is to include parameters depending on the financier's decisions. Thus the macro-economic impacts of a credit policy can be estimated for a region or for a branch. A simplified game model translating the experiences of the model of the firm takes the uncertainty of our knowledge into account and makes us choose a less risky solution. Finally, the problem of the optimal equilibrium between « heavy » and « light » investments can be approached in this model.
