The ex-Ante non-optimality of the Dempster-Schafer updating rule for ambiguous beliefs
1992-02The most widely used updating rule for non-additive probalities is the Dempster-Schafer rule. Schmeidles and Gilboa have developed a model of decision making under uncertainty based on non-additive probabilities, and in ... -
Inada conditions imply that production function must be asymptotically Cobb-Douglas
2003-03-25We show that every twice-continuously differentiable and strictly concave function f : R+ → R+ can be bracketed between two C.E.S. functions at each open interval. In particular, for the Inada conditions to hold, a production ... -
Nash equilibrium under knightian uncertainty: breaking down backward induction (extensively revised version)
1993-04We define Nash equilibrium for two-person normal form games in the presence of uncertainty, in the sense of Knight(1921). We use the fonna1iution of uncertainty due to Schmeidler and Gilboa. We show tbat there exist Nash ... -
Nash equilibrium under knightian uncertainty: breaking-down backward induction
1992-02We present two alternative definitions of Nash equilibrium for two person games in the presence af uncertainty, in the sense of Knight. We use the formalization of uncertainty due to Schmeidler and Gilboa. We show that, ... -
On a uniform turnpike of the third kind in the Robinson-Solow-Srinivasan model
2007-01-01On using McKenzie’s taxonomy of optimal accumulation in the longrun, we report a 'uniform turnpike' theorem of the third kind in a model original to Robinson, Solow and Srinivasan (RSS), and further studied by Stiglitz. ... -
On choice of technique in the Robinson-Solow-Srinivasan model
2003-10-08We report results on the optimal \choice of technique' in a model originally formulated by Robinson, Solow and Srinivasan (henceforth, the RSS model) and further discussed by Okishio and Stiglitz. By viewing this vintage-capital ... -
Resultados uniformemente seguros e equilíbrio de Nash em jogos compactos
2006-09-01Nós introduzimos uma condição, resultados uniformemente seguros, para jogos compactos e resultados ('payoffs') limitados e mensur´aveis nas estrat´egias. Demonstramos que se um jogo compacto tem resultados uniformemente ... -
Solving the non-convexity problem in some shopping-time and human-capital models
2004-09-01Several works in the shopping-time and in the human-capital literature, due to the nonconcavity of the underlying Hamiltonian, use Örst-order conditions in dynamic optimization to characterize necessity, but not su¢ ciency, ...
