“…They showed that the difference between results with the constant and variable capital-to-output ratio were not significant. Other studies estimated output gap for the Czech republic with different methods, for example Dybzcak, Flek, Hájková a Hurník (2006), Beneš and N´Diaye (2004), who used multivariate unobserved component model, or Plašil (2011), who analysed univariate HP filter. From newer studies we can mentioned e. g. Kloudová (2013a) who analysed ability of output gap for the Czech republic (methods of estimation were HP filter, SVAR model and multivariate unobserved component model) to indicate inflation.…”
