On Lipschitz continuity of policy functions in continuous-time optimal growth models

Gota, Maria Luisa; Montrucchio, Luigi - In: Economic Theory 14 (1999) 2, pp. 479-488

This paper proves the C1,1 differentiability of the value function for continuous time concave dynamic optimization problems, under the assumption that the instantaneous utility is C1,1 and the initial segment of optimal solutions is interior. From this result, the Lipschitz dependence of...

Notes on some inequalities in economics

Färe, Rolf; Grosskopf, Shawna - In: Economic Theory 15 (2000) 1, pp. 227-233

Inequalities created by relating gauge (distance) functions and their dual support functions have been used in … short paper we add to this literature by providing explicit relationships between distance functions and support functions … to form five different inequalities. These inequalities are derived from three support functions: the cost function, the …

A Theoretical Frameworkfor Abundance Distributions in Complex Systems

Halloy, Stephan R. P. - Santa Fe Institute - 1999

lead to diversification and to abundance distributions which are similar to power functions on a rank …-abundance representation and to lognormal functions on a frequency-abundance representation. The combined manifestation of power and lognormal … functions is a polo distribution, a situation toward which there seems to be a widespread tendency in complex systems (a polo …

Re-Employment Probabilities and Returns to Matching

Petrongolo, Barbara - C.E.P.R. Discussion Papers - 1999

The assumption of constant returns in the matching function, embodied in most bilateral search models, is crucial to ensure the uniqueness of the unemployment rate along a steady state growth path. This paper explores whether this is an acceptable assumption by estimating individual...

On the structure of choice under different external references

Gaertner, Wulf; Xu, Yongsheng - In: Economic Theory 14 (1999) 3, pp. 609-620

In this paper we fully characterize an individual's choice behaviour according to three different so-called external references. The first system which we describe axiomatically is standard utility maximization or preference optimization. The second approach characterizes the choice of the...
