The purpose of this article is to analyze the macroeconomic impacts of fiscal policy in Iran using a new-Keynesian Dynamic Stochastic General Equilibrium (DSGE) model. The model takes into account distortionary taxations on wage, dividend, and consumption, while government expenditures are broken down into consumption of goods and services, and investment. The model is calibrated for Iran based...

We analyze infinite-horizon choice functions within the setting of a simple technology. Efficiency and time consistency are characterized by stationary consumption and inheritance functions, as well as a transversality condition. In addition, we consider the equity axioms Suppes-Sen, Pigou-Dalton, and resource monotonicity. We show that Suppes-Sen and Pigou-Dalton imply that the consumption and...

Abstract We consider a two-machine flow shop scheduling problem in which the processing time of each operation is inversely proportional to power amount resources consumed by it. The objective minimize sum makespan and total resource consumption cost. show that NP-hard, its constrained version remains so. Then, we develop 1.25- 2-approximation algorithms for version, respectively.

Abstract Given two probability distributions expressing returns on single risky assets of a portfolio, we innovatively define consumer’s demand functions connected with contingent consumption plans. This thing is possible whenever coherently summarize every distribution being chosen by the consumer. Since prevision choices are made consumer inside metric space, show that can be studied means st...

In this paper, the impacts of the uncertainty of fuel heating value as well as the burner efficiency on performance functions of a turbofan engine are studied. The mean value and variance curves for thrust, thrust specific fuel consumption as well as propulsive, thermal and overall efficiencies are drawn and analyzed, considering the aforementioned uncertainties based on various Mach numbers at...

Zeldes (1989), Carroll (1992; 1993), and others have shown that optimal consumption behavior for consumers facing income uncertainty can be remarkably di erent from the certainty-equivalent case. Carroll (1992; 1993) observes that many of the di erences can be attributed to the concavity of the consumption function under uncertainty, but he does not describe the conditions under which the consu...

In this research, the effect of shape parameters such as number of magnet wire turns, spools, thickness of the gap, and pole length in a Magneto-rheological (MR) fluid damper is analytically investigated and the optimization of these parameters is done with response surface method (RSM) which is combined Neuro-Fuzzy method and Particle Swarm Optimization (PSO) algorithm. Since the electro-magne...

S. Kuznets's study that the average propensity to consume is a constant value were nexpected because they denied one of the basic provisions of the Keynesian theory. This fact was called "the riddle of Kuznets".  F. Modigliani and M. Friedman, using the hypothesis of the life cycle and the concept of constant income, proposed two options that explain its solution. But models should not explain,...
