Economic growth and environmental efficiency: Evidence from US regions
Halkos, G. E.; Tzeremes, N. G. (2013)This paper proposes a conditional directional distance function estimator in order to examine the link between regional environmental efficiency and GDP per capita levels. As an illustrative example we apply our model to ... -
THE EFFECT OF ACCESS TO IMPROVED WATER SOURCES AND SANITATION ON ECONOMIC EFFICIENCY: THE CASE OF SUB-SAHARAN AFRICAN COUNTRIES
Halkos, G. E.; Tzeremes, N. G. (2012)This paper evaluates the effect of access to improved water sources and sanitation on 41 sub-Saharan African (SSA) countries' economic efficiency and growth. For this reason data envelopment analysis (DEA), bootstrap ... -
The effect of electricity consumption from renewable sources on countries' economic growth levels: Evidence from advanced, emerging and developing economies
Halkos, G. E.; Tzeremes, N. G. (2014)This paper uses a sample of 36 countries for the time period 1990-2011 in order to examine the relationship between countries' electricity consumption from renewable sources and Gross Domestic Product (GDP) levels. Several ... -
The effect of foreign ownership on SMEs performance: An efficiency analysis perspective
Halkos, G. E.; Tzeremes, N. G. (2010)This paper uses both Data Envelopment Analysis (DEA) and Free Disposal Hull (FDH) models in order to determine different performance levels in a sample of 353 foreign equities operating in the Greek manufacturing sector. ... -
The effect of government expenditure on the environment: An empirical investigation
Halkos, G. E.; Paizanos, E. A. (2013)This paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980-2000. We estimate both the direct and indirect effects of government spending on pollution. ... -
Efficiency measurement of the Greek commercial banks with the use of financial ratios: A data development analysis approach
Halkos, G. E.; Salamouris, D. S. (2004)This study offers an application of a non-parametric analytic technique (data envelopment analysis, DEA) in measuring the performance of the Greek banking sector. It explores the efficiency of Greek banks with the use of ... -
Electricity Generation and Economic Efficiency: Panel Data Evidence from World and East Asian Countries
Halkos, G. E.; Tzeremes, N. G. (2009)Taking a commonly-used and commonly-available trade policy model as our starting point, we examine the long-run effects of large-scale structural change with and without international capital accumulation, mobility and ... -
Environmental Kuznets Curve for sulfur: evidence using GMM estimation and random coefficient panel data models
Halkos, G. E. (2003)The purpose of this study is to test empirically the hypothesis of the inverted U-shaped relationship between environmental damage from sulfur emissions and economic growth as expressed by GDP. Using a large database of ... -
Environmental Kuznets curves: Bayesian evidence from switching regime models
Halkos, G. E.; Tsionas, E. G. (2001)The purpose of the paper is to test empirically the existence of an environmental Kuznets curve (EKC), using switching regime models along with cross-sectional data and Bayesian Markov chain Monte Carlo methods to perform ... -
Estimating the degree of operating efficiency gains from a potential bank merger and acquisition: A DEA bootstrapped approach
Halkos, G. E.; Tzeremes, N. G. (2013)We propose a bootstrapped Data Envelopment Analysis (DEA)-based procedure to pre-calculate and pre-evaluate the short-run operating efficiency gains of a potential bank merger or acquisition (M&A). As an illustrative ... -
Evaluating alternative Frequentist inferential approaches for optimal order quantities in the newsvendor model under Exponential demand
Halkos, G. E.; Kevork, I. S. (2013)Three estimation policies for the optimal order quantity of the classical newsvendor model when the demand is Exponentially distributed are evaluated in this paper. The evaluation is performed analytically for different ... -
Exploring the economy - environment relationship in the case of sulphur emissions
Halkos, G. E. (2013)This paper explores the relationship between economic development and environmental pollution by using panel data for 97 countries for the period 19502003. Various econometric techniques are applied to a sample of European ... -
Exploring the existence of Kuznets curve in countries' environmental efficiency using DEA window analysis

Financial and real sector interactions: The case of Greece
Halkos, G. E.; Trigoni, M. K. (2010)In this study we try to detect the relationship between financial and real sector employing in the estimation procedure the recent time-series techniques of co-integration, vector error-correction modelling and Granger ... -
Forecasting the stationary AR(1) with an almost unit root
Halkos, G. E.; Kevork, I. S. (2006)Although unit root tests have made a great contribution in time series econometrics, their major disadvantage is the low powers they attain on certain occasions, as for the case of the stationary AR(1), when phi is close ... -
