Machine Replacement, Network Externalities, and Investment Cycles
This paper presents a model where agents decide on the timing of replacement of ageing machines. The optimal replacement policy for an agent is influenced by other agents’ decisions because the productivity of a particular vintage displays network externalities that set in with a lag. In equilibrium, agents follow innovation cycles with a frequency that is lower than optimal, so there is too mu...
متن کاملOn Sen and Aristotle
In this paper I maintain that Amartya Sen’s Capability Approach (CA) implies a recuperation of practical science in Economics. Sen’s proposal has some problems closely related to this practical character: the heterogeneity and incommensurability of capabilities, its ambiguity concerning the use of the term “capability”, and the consequent lack of operative character of the CA. Sen recognizes th...

We analyze M-theory compactified on (K3 × S)/Z2 where the Z2 changes the sign of the three form gauge field, acts on S as a parity transformation and on K3 as an involution with eight fixed points preserving SU(2) holonomy. At a generic point in the moduli space the resulting theory has as its low energy limit N = 1 supergravity theory in six dimensions with eight vector, nine tensor and twenty...
متن کاملAmartya Sen and the media
Amartya Sen has correctly sought to correct some shortcomings within neoclassical economic theory. Nonetheless, there still exists a tension in his work. His overall frame of analysis is still congruent with much of the neoclassical tradition. However, his critiques seem to imply that a sharp break with neoclassical theory is necessary. This conflict is examined in light of the connections betw...
متن کاملSen - R 9708 1997
We study equational axiomatizations of bisimulation equivalence for the language obtained by extending Milner's basic CCS with string iteration. String iteration is a variation on the original binary version of the Kleene star operation p q obtained by restricting the rst argument to be a non-empty sequence of atomic actions. We show that, for every positive integer k, bisimulation equivalence ...
