Fernández Díaz, AndrésGrau Carles, Pilar2013-01-222013-01-222012http://hdl.handle.net/10115/11549Complexity is one of the most important characteristic properties of the economic behaviour. The new field of knowledge called Chaotic Dynamics Economics born precisely with the objective of understanding, structuring and explaining in the endogenous way such complexity. In this paper we begin with a reappraisal of the Efficient Market Hypothesis, the fundamental and chart analysis and the modelization of the capital markets and chaos. Principally, we analyze the capital market from the point of view of complexity and chaos, by making reference to the behaviour of the Madrid stock exchange, in the period of 1941-1998 for the General Index, and during the period transpired between 1987-1998 for the daily Ibex35 index. In the work we show the need of knowing with independence of the irregularity, if the time series is stochastic or deterministic with a hidden explanation. That is the key problem to take into account.enAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ComplejidadCaosMercado eficienteinfo:eu-repo/semantics/workingPaperinfo:eu-repo/semantics/openAccess5309.04 Estructura del Mercado5311.06 Estudio de Mercado
