Celles-ci empêchent la monétisation des revenus futurs et génèrent une incomplétude endogène des marchés financiers. En contraste avec la littérature récente sur les contraintes d'investissement, nos contraintes de liquidité émergent naturellement lorsque les agents peuvent déclarer faillite et ont un horizon fini. Un individu, dont la contrainte de liquidité sature, decide optimalement (i) de déférer sa consommation en période de jeunesse, mais (ii) de l'augmenter lorsque la contrainte est active. Le taux d'intérêt et les prix des actifs financiers d'équilibre sont caractérisés sous des conditions générales sur les préférences et les dotations. En présence de contraintes de liquidité le rendement de l'actif non risqué décroît. De plus le CAPM par rapport à la consommation est valide, même lorsque la structure de base du marché est incomplète. Lorsque l'aversion relative par rapport au risque est homogène et constante l'incomplétude du marché renforce l'effet des contraintes de liquidité et réduit encore davantage le rendement non risqué. Cependant, ni la contrainte d'incomplétude, ni celles de liquidité ne nous …

Liquidity Constraints and Precautionary Savings: A Quantitative Analysis

In this paper I quantify the effects of liquidity constraint and precautionary motive of savings in the framework of a stochastic dynamic general equilibrium model. I show that the Zeldes’s estimate [13] of the excess consumption growth for the low asset holders is consistent with the framework when the borrowing constraint point is three months’ worth of average wage income. A Monte Carlo test...

An efficient monetary and tax system plays an important role in the proper performance of the economic system, and can effect on motivation of labor, consumer, savings and investment behavior. A theory of monetary and tax reform is movement of the income tax system and inflation tax to the system of consumption tax, that can increase the tendency to savings, investment and capital accumulation....

Liquidity shocks and equilibrium liquidity premia

We study an equilibrium in which agents face surprise liquidity shocks and invest in liquid and illiquid riskless assets. The random holding horizon from liquidity shocks makes the return of the illiquid security risky. The equilibrium premium for such risk depends on the constraint that agents face when borrowing against future income; it is insignificant without borrowing constraint, but can ...

Evaluation of Monetary and Fiscal Policy Based on New Keynesian Dynamic General Equilibrium Model in Iran’s Economy

This paper examines monetary and fiscal policy through the estimation of a New-Keynesian dynamic general equilibrium model for Iran’s economy. In this New-Keynesian dynamic general equilibrium model, the consumers encounter the liquidity constraint and the firms face sticky prices, while they are changing them. In the model presented, a role is considered for both government spending and taxati...

The Comparison of Direct and Indirect Optimization Techniques in Equilibrium Analysis of Multibody Dynamic Systems

The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons are made between these techniques. A computer program is developed to evaluate the equality co...

Asset Pricing Implications of Short-sale Constraints in Imperfectly Competitive Markets

We propose an equilibrium model to study the impact of short-sale constraints on market prices and liquidity in imperfectly competitive markets where market makers have significant market power and are averse to inventory risk. We show that shortsale constraints decrease bid because of the market power and increase ask because of the risk aversion. Our model can therefore help explain why short...
