Measuring Complexity in Financial Data

Complexity in Financial Markets

Should we regulate complex securities, subject them to an FDA-style approval process, or limit who can invest in them? To answer these questions, one first needs to establish why complexity matters, and what defines a complex security. Complexity is an important concept in financial markets with boundedly rational agents, but that finding a workable definition of complexity is difficult. For ex...

Measuring the Effectiveness of Financial Literacy Programs in Ghana

This paper explores the effectiveness of financial literacy programs. It further seeks to establish the relationship between financial literacy and certain demographic characteristics. This study adopted a correlational research design as the framework to examine the relationship between variables without determining cause and effect. Data were randomly collected from 235 petty traders in Kumas...

Efficiently Measuring Complexity on the Basis of Real-World Data

Permutation entropy, introduced by Bandt and Pompe, is a conceptually simple and well-interpretable measure of time series complexity. In this paper, we propose efficient methods for computing it and related ordinal-patterns-based characteristics. The methods are based on precomputing values of successive ordinal patterns of order d, considering the fact that they are “overlapped” in d points, ...
