This paper studies a unique panel dataset of transactions with repeat customers of an insurer operating in a market in which insurers are not required by law or contract to share information about their customers' records. I use this dataset to test the asymmetric learning hypothesis that...

This paper models the supply of perishable goods within a randon framework. Perishability affects a large group of goods usually traded in the economy such as fruits and vegetables, newspapers, medicine drugs, a.s.o.. Surprisingly, one cannot find in the literature a decision model for suppliers...

Asymmetric kernels are quite useful for the estimation of density functions which have bounded support. Gamma kernels are designed to handle density functions whose supports are bounded from one end only, whereas beta kernels are particularly convenient for the estimation of density functions...

The Jordan Form of the VAR's Companion matrix is used for proving the equivalence between the statement that there are no jordan blocks of order two or higher in the Jordan matrix and the conditions of Granger's Representation Theorem for an I(1) series. Furthermore, a Diagonal polynomial matrix...

This article explains how changing many structural parameters by discrete amounts affect many variables of interest when we have no explicit expressions for the variables of interest in terms of the structural parameters. Although the matrix multiplying a vector of discrete changes in parameters...

A "dispersion" specifies the relative probability between any two elements of a finite domain. It thereby partitions the domain into equivalence classes separated by infinite relative probability. The paper's novelty is to numerically represent not only the order of the equivalence classes, but...

We provide two, new simple proofs of Afriat's celebrated theorem..

This paper proposes an expected utility framework for the treatment of theoretical and empirical issues in technical analysis. Circumstances are found in which a technical analysts' behaviour is 'rationalisable' and schemes for learning such rational behaviour are considered. The decision...

This paper discusses the intellectual origins of the so-called 'new economic geography' and provides its basic insights by means of a streamlined framework which stresses the generality of their implications.

In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...
