    Wage stickiness and unemployment fluctuations: an alternative approach
    (2009) Casares Polo, Miguel; Moreno Pérez, Antonio; Vázquez, Jesús; Economía; Ekonomia
    Erceg, Henderson and Levin (2000, Journal of Monetary Economics) introduce sticky wages in a New-Keynesian general-equilibrium model. Alternatively, it is shown here how wage stickiness may bring unemployment fluctuations into a New-Keynesian model. Using Bayesian econometric techniques, both models are estimated with U.S. quarterly data of the Great Moderation. Estimation results are similar and provide a good empirical fit with the crucial difference that our proposal delivers unemployment fluctuations. Thus, second-moment statistics of U.S. unemployment are replicated reasonably well in our proposed New-Keynesian model with sticky wages. In the welfare analysis, the cost of cyclical fluctuations during the Great Moderation is estimated at 0.60% of steady-state consumption.

    An estimated new-Keynesian model with unemployment as excess supply of labor
    (2010) Casares Polo, Miguel; Moreno Pérez, Antonio; Vázquez, Jesús; Economía; Ekonomia
    As one alternative to search frictions, wage stickiness is introduced in a New-Keynesian model to generate endogenous unemployment fluctuations due to mismatches between labor supply and labor demand. The effects on an estimated New-Keynesian model for the U.S. economy are: i) the Calvo-type probability on wage stickiness rises, ii) the labor supply elasticity falls, iii) the implied second-moment statistics of the unemployment rate provide a reasonable match with those observed in the data, and iv) wage-push shocks, demand shifts and monetary policy shocks are the three major determinants of unemployment fluctuations.

    Learning fuzzy measures for aggregation in fuzzy rule-based models
    (Springer Verlag, 2018) Saleh, Emran; Valls, Aida; Moreno Pérez, Antonio; Romero-Aroca, Pedro; Torra, Vicenç; Bustince Sola, Humberto; Ingeniería; Ingeniaritza
    Fuzzy measures are used to express background knowledge of the information sources. In fuzzy rule-based models, the rule confidence gives an important information about the final classes and their relevance. This work proposes to use fuzzy measures and integrals to combine rules confidences when making a decision. A Sugeno $$\lambda $$ -measure and a distorted probability have been used in this process. A clinical decision support system (CDSS) has been built by applying this approach to a medical dataset. Then we use our system to estimate the risk of developing diabetic retinopathy. We show performance results comparing our system with others in the literature.

    Wage stickiness and unemployment fluctuations: an alternative approach
    (Springer, 2012) Casares Polo, Miguel; Moreno Pérez, Antonio; Vázquez, Jesús; Economía; Ekonomia
    Erceg et al. (J Monet Econ 46:281–313, 2000) introduce sticky wages in a New-Keynesian general-equilibrium model. Alternatively, it is shown here how wage stickiness may bring unemployment fluctuations into a New-Keynesian model. Using a Bayesian econometric approach, bothmodels are estimated with US quarterly data of the Great Moderation. Estimation results are similar in the two models and both provide a good empirical fit, with the crucial difference that our model delivers unemployment fluctuations. Thus, second-moment statistics of the US rate of unemployment are replicated reasonably well in our proposed New-Keynesian model with sticky wages. Demand-side shocks play a more important role than technology innovations or cost-push shock in explaining both output and unemployment fluctuations. In the welfare analysis, the cost of cyclical fluctuations during the Great Moderation is estimated at 0.60% of steady-state consumption.
