Semiparametric estimation in perturbed long memory series
(2005-05)
The estimation of the memory parameter in perturbed long memory series has recently attracted attention motivated especially by the strong persistence of the volatility in many financial and economic time series and the ...
Bayesian learning in mis-specified models
(2000-02)
A central unanswered question in economic theory is that of price formation in disequilibrium. This paper lays down the methodological groundwork for a model that has been suggested as an answer to this question (Arrow, ...
La Educación Ocupacional y la Salida del Paro en España
(1999-10)
[EN] This paper considers the estimation of the effect of vocational education on the probability of employment using Spanish data from the linked Active Population Survey (EPA) since 1992 to 1997. After allowing for ...
Gaussian Semiparametric Estimation in Long Memory in Stochastic Volatility and Signal Plus Noise Models
(2002-04)
This paper considers the persistence found in the volatility of many financial time series by means of a local Long Memory in Stochastic Volatility model and analyzes the performance of the Gaussian semiparametric or local ...
Semiparametric inference in correlated long memory signal plus noise models
(2010-04)
This paper proposes an extension of the log periodogram regression in perturbed long memory series that accounts for the added noise, also allowing for correlation between signal and noise, which represents a common situation ...
Doubly fractional models for dynamic heteroskedastic cycles
(2011-02)
Strong persistence is a common phenomenon that has been documented not only in the levels but also in the volatility of many time series. The class of doubly fractional models is extended to include the possibility of long ...
A note on Lopez-Hernandez procedure: New non-hierarchical algorithms in classification of data
(2000-03)
[EN] In this short note, we make a critique about the procedure developed in the Inductive Algorithm in the Objects of Lopez-Hernandez (1997). It is well known that the determination of maximal cliques in a graph is an ...
Fractional Integration Analysis and its Implications on Profitability: the Case of the Mackerel Market in the Basque Country
(2010)
This paper analyses weekly prices for mackerel landed by the inshore fleet at the ports of the Basque Country in 1995-2008, using new econometric techniques never before applied to the fishing market. The idea is to learn ...
Estacionalidad determinista y estocástica en series temporales macroeconómicas
(2004-12)
Basándose en la literatura existente, en este trabajo se propone una metodología para el estudio gráfico y analítico del componente estacional en una serie temporal. El objetivo del análisis es determinar si el componente ...
Consumption-Leisure Trade-offs and Persistency in Business Cycles
(2007)
This paper studies whether nonseparabilities between consumption and leisure may help to explain the observed persistence in GNP growth. We consider an extended version of Lucas' (1988) human capital investment model that ...
