Expedient and Monotone Learning Rules
This paper considers learning rules for environments in which little prior and feedback information is available to the decision maker. Two properties of such learning rules are studied: absolute expediency and monotonicity. Both require that some aspect of the decision maker’s performance improves from the current period to the next. The paper provides some necessary, and some sufficient condi...
متن کاملA note on absolutely expedient learning rules
I provide a full characterization of the set of absolutely expedient learning rules introduced in Börgers, Morales, and Sarin (2004) [“Expedient and monotone learning rules,” Econometrica, 72, 383–405]. The expected change in the expected payoff can be written as a quadratic form on the vector of relative expected payoffs of the strategies. This permits use of standard linear algebra arguments ...
متن کاملCollective rationality and monotone path division rules
We impose the axiom Independence of Irrelevant Alternatives on division rules for the conflicting claims problem. With the addition of Consistency and Resource Monotonicity, this characterizes a family of rules which can be described in three different but intuitive ways. First, a rule is identified with a fixed monotone path in the space of awards, and for a given claims vector, the path of aw...
متن کاملDiscovering Rules That Govern Monotone Phenomena
Unlocking the mystery of natural phenomena is a universal objective in scientific research. The rules governing a phenomenon can most often be learned by observing it under a sufficiently large number of conditions that are sufficiently high in resolution. The general knowledge discovery process is not always easy or efficient, and even if knowledge is produced it may be hard to understand, int...
متن کاملInverted orders for monotone scoring rules
When each of n judges ranks a set A of m objects from best to worst, and s= (~1, . . . ,sm) is a decreasing sequence of real numbers, the collective ranking determined by s orders the objects in A according to their total scores. The total score of x equals sp times the number of judges w’ho rank x in pth place, summed over p. For normalization purposes, let S, denote the set of all decreasing ...
