In this article, the innovative twostage procedure of Simar and Wilson (2007) is used to estimate the efficiency determinants of Portuguese hotel groups from 1998 to 2005. In the first stage, the hotels' technical efficiency is estimated with Data Envelopment Analysis (DEA), in order to...

We employ the Luenberger productivity indicator to estimate productivity growth and its decomposition into technical change and efficiency change components for savings banks sectors in 10 EU countries between 1996 and 2003. The Luenberger indicator requires less restrictive assumptions than...

This paper evaluates the operational activities of African airports using a finite mixture model that allows us to control for unobserved heterogeneity. In doing so, a stochastic frontier latent class model, which allows for the existence of different technologies, is adopted to estimate cost...

In the housing market, new properties sometimes experience delays before they are sold. Such delays reflect the preferences of buyers in respect of the homes’ characteristics. Therefore, it is important for managerial purposes to identify the causes of housing sales delays. After analyzing the...

The rise of oil prices is a main issue in contemporary economics. This study examines the monthly, weekly and daily structure in several oil prices series using a modeling approach based on fractional integration and long range dependence. The results indicate that oil prices series are highly...

This paper evaluates the operational activities of Chinese hydroelectric power companies over the period 2000–2010 using a finite mixture model that controls for unobserved heterogeneity. In so doing, a stochastic frontier latent class model, which allows for the existence of different...

This study examines the degree of persistence, potential breaks and outliers of oil production for OPEC member countries within a fractional integration modelling framework using monthly data from January 1973 to October 2008. The results indicate there is mean reverting persistence in oil...

This study examines the long-memory properties of German energy price indices (specifically, import and export prices, as well as producer and consumer prices) for hard coal, lignite, mineral oil and natural gas adopting a fractional integration modelling framework. The analysis is undertaken...

This study investigates the relationship between U.S. state housing prices and overall U.S. housing prices as well as the relationship among state housing prices using fractional integration and cointegration techniques. The results based on parametric and semiparametric estimators reveal that...
