This title was first published in 2002: Why do endogenous cycles persist in Spain? Manuel Roman demonstrates a highly novel approach to the study of finance and the persistence of endogenous growth cycles, providing a balanced account of the Post Keynesian, Classical and Neo-classical political economy approaches. Finding key propositions from a representative set of heterodox cycles' models, he rigorously tests their chief claims, grounding his research in empirical data. The endogenous forces behind persistent fluctuations in the Spanish economy are also identified and explored in this theoretically rich text, the first of its kind to examine the Spanish economy in such great detail.
