Based on 58,256 news articles published in the Financial Times during a 15-year period that cover companies in the DJIA, we find that a trading strategy that longs stocks with the most negative news and shorts stocks with the least negative news is not profitable. Consistent with this result, we...

The purpose of this paper is to show how the stability properties of non-linear dynamic models may be characterized and studied, where the degree of stability is defined by the effects of exogenous shocks on the evolution of the observed stochastic system. This type of stability concept is...

It is shown in this letter that the magnitude of exchange rate overshooting is larger than in Dornbusch (1976) when chartists are introduced into the model. Also, the extent of overshooting depends inversely on the planning horizon. The latter follows from explicitly modelling the empirical...

We show that the Matthew effect, or Matthew mechanism, was present in the artificial cultural market Music Lab when social influence between individuals was allowed, whereas this was not the case when social influence was not allowed. We also sketch on a class of social network models, derived...

The aim of this article is to demonstrate how the change in actual and potential market risks in the Dow Jones Industrial Average (DJIA) during the 2-year period 2007 to 2008 can be analysed with the help of (<italic>λ</italic>, <italic>σ</italic> -super-2)-analysis. In the empirical analysis, the average of the Lyapunov...

We show that the Matthew effect, or Matthew mechanism, was present in the artificial cultural market Music Lab in one-fourth of the “worlds” when social influence between individuals was allowed, whereas this effect was not present in the “world” that disallowed social influence between...

ABSTRACT We argue that it is not necessary for the central bank to react to the exchange rate to have a desirable outcome in the economy. Indeed, when the Taylor rule includes contemporaneous data on the variables in the rule, the central bank can disregard from the exchange rate as long as...
