We develop easy-to-verify conditions assuring that comparative statics in a general equilibrium model where time is a real line is feasible, i.e., the implicit function theorem is applicable. Consider an equilibrium equation, Υ(k,E) = k of a model where an equilibrium variable (k) is a continuous bounded function of time, real line, and the policy parameter (E) is a locally integrable function ...

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...

A firm chooses a price and how much information to disclose about its product to a consumer whose tastes are unknown to the firm. Full disclosure of product information is always part of a sequential equilibrium when types are independent. In that case, a necessary and sufficient condition on equilibrium payoffs is that they are at least as high as those under full revelation for all product ty...

It is shown that (except for two well defined cases), the necessary and sufficient condition for any spherically symmetric distribution of fluid to leave the state of equilibrium (or quasi–equilibrium), is that the Weyl tensor changes with respect to its value in the state of equilibrium (or quasi–equilibrium). ∗Postal address: Apartado 80793, Caracas 1080A, Venezuela; E-mail address: laherrera...

Expansive soils can be found in many parts of the world particularly in arid and semi-arid regions. These soilspose a significant hazard to civil engineering structures due to its high swelling and shrinkage potential. This paperpresents the results of an experimental program developed to investigate the effect of cyclic drying and wetting on theswelling potential of expansive soils with variou...

The relationship between coalition-proof equilibria in a normal-form game and those in its subgame is examined. A subgame of a normal-form game is a game in which the strategy sets of all players in the subgame are subsets of those in the normal-form game. Ray (2001) proved that a Nash equilibrium of a subgame is a Nash equilibrium of the original game under the condition of no unilateral benef...
