We numerically find unstable periodic solutions embedded in a chaotic attractor in a generalized Goodwin model with an interaction between two countries and focus on a class of simple periodic orbits extracted from them. We confirm that chaotic behaviour represented by the model is qualitatively...

Synchronization is a phenomenon in which a pair of fluctuations adjust their rhythms when interacting with each other. We measure the degree of synchronization between the U.S. dollar (USD) and euro exchange rates and between the USD and Japanese yen exchange rates based on purchasing power...
