budget plays an important role in public sector management and administration .one of its components is revenues forecasting and without the necessary accuracy in predicting revenues, government deficit will occur and people are incapable of facing with losses of reducing of important and essential services like education and health care. in this study, the rational expectations hypothesis is a...

A necessary feature for equilibrium is that beliefs about the behavior of other agents are rational and individuals maximize. We argue that in stationary OLG environments this implies that any future generation in the same situation as the initial generation must do as well as the initial generation did in that situation. We conclude that the existing equilibrium concepts in the literature do n...

First order algebraic differential equations are considered. An necessary condition for a first order algebraic differential equation to have a rational general solution is given: the algebraic genus of the equation should be zero. Combining with Fuchs’ conditions for algebraic differential equations without movable critical point, an algorithm is given for the computation of rational general s...

Projectification is the phenomenon whereby activities traditionally carried out in a functional manner are approached as projects. It also includes transformation processes of organisations project management and non-functional structures. that has become important recent years. brought great benefits to public administration, it optimised use economic resources. On other hand, projectification...
