We investigate the potential occurrence of change points—commonly referred to as “momentum shifts”—in the dynamics of football matches. For that purpose, we model minute-by-minute in-game statistics of Bundesliga matches using hidden Markov models (HMMs). To allow for within-state...

Writing in Applied Economics Letters, Sumner (2004) advocates use of long lag lengths when conducting cointegration tests. Replication of Sumner’s consumption model suggests long lag lengths are a mis-specification: The true underlying model is periodic. We test for periodically distributed...

Assuming the existence of Hegel‟s consistent overall picture of the concept of entropy, the author transfers the physical term of entropy into economics and sociology and illuminates the relevance of second law of thermodynamics within both disciplines. Basis of translation is the present...

The rapidly growing literature on the relationship between energy consumption and economicgrowth has not univocally identi…ed the ‘real’causal relationship yet. We argue that bivariate mod-els, which analyze the causality at the level of the total economy, are not appropriate — especiallyin...

Inter-rm competition has received much attention in the theoreticalliterature, but recent empirical work suggests that the growth rates of ri-val rms are uncorrelated, and that rm growth can be taken as an essen-tially independent process. We begin by investigating the correlations of thegrowth...
