Industry performance evaluation with the use of financial ratios: An application of bootstrapped DEA
Halkos, G. E.; Tzeremes, N. G. (2012)In data envelopment analysis (DEA) context financial data/ratios have been used in order to produce a unified measure of performance metric. However, several scholars have indicated that the inclusion of financial ratios ... -

Measuring biodiversity performance: A conditional efficiency measurement approach
Halkos, G. E.; Tzeremes, N. G. (2010)This paper uses a methodological framework based on the new advances of Data Envelopment Analysis (DEA) and a sample of 71 developed, developing and under-developed countries to model and evaluate their biodiversity ... -
Measuring economic journals' citation efficiency: a data envelopment analysis approach
Halkos, G. E.; Tzeremes, N. G. (2011)This paper by using data envelopment analysis (DEA) and statistical inference evaluates the citation performance of 229 economic journals. The paper categorizes the journals into four main categories (A-D) based on their ... -
Measuring German regions' environmental efficiency: A directional distance function approach
Halkos, G. E.; Tzeremes, N. G. (2012)This paper by applying a directional distance function approach measures German regions' municipality waste performance. By applying the weak disposability assumption the paper constructs environmental performance indexes ... -
Measuring regional economic efficiency: the case of Greek prefectures
Halkos, G. E.; Tzeremes, N. G. (2010)This paper, using Data Envelopment Analysis (DEA), measures for the first time the economic growth policies of the Greek prefectures. Based on the neoclassical model of growth it uses private and public investments and ... -
Measuring Sustainability Efficiency Using a Two-Stage Data Envelopment Analysis Approach
Halkos, G. E.; Tzeremes, N. G.; Kourtzidis, S. A. (2015)In this article, we apply an additive two-stage data envelopment analysis estimator on a panel of 20 countries with advanced economies for the time period 1990-2011 in order to create a composite sustainability efficiency ... -
Measuring the effect of Kyoto protocol agreement on countries' environmental efficiency in CO2 emissions: an application of conditional full frontiers
Halkos, G. E.; Tzeremes, N. G. (2014)This paper applies the probabilistic approach developed by Daraio and Simar (J Prod Anal 24:93-121, 2005, Advanced robust and nonparametric methods in efficiency analysis. Springer Science, New York, 2007a, J Prod Anal ... -
Modelling Regional Welfare Efficiency Applying Conditional Full Frontiers
Halkos, G. E.; Tzeremes, N. G. (2011)This paper demonstrates an evaluation of welfare policies and regional allocation of public investment using the recent developments in efficiency analysis and statistical inference. Specifically, the efficiency of the ... -
Modelling the effect of national culture on countries' innovation performances: A conditional full frontier approach
Halkos, G. E.; Tzeremes, N. G. (2013)This paper provides empirical evidence of the link between countries' cultural factors and innovation performance. By defining innovation process in a knowledge production framework it uses conditional and unconditional ... -
Modelling the effect of national culture on multinational banks' performance: A conditional robust nonparametric frontier analysis
Halkos, G. E.; Tzeremes, N. G. (2011)Most of the efficiency studies of large multinational banks operating in different countries calculate banks' inefficiency levels without taking into account the environmental factors in which they are operating in. As a ... -
National culture and eco-efficiency: An application of conditional partial nonparametric frontiers
Halkos, G. E.; Tzeremes, N. G. (2013)Given that norms govern individual behaviour, which in turn are related to the environmental behaviour, this study provides empirical evidence of the link between human behaviour and the environment. Firstly with the use ... -
Oil consumption and economic efficiency: A comparative analysis of advanced, developing and emerging economies
Halkos, G. E.; Tzeremes, N. G. (2011)This paper investigates the economic efficiency-oil consumption relationship in 42 countries during the period 1986-2006. In a first stage by using DEA window analysis countries' economic efficiencies are obtained. In a ... -
Population, economic growth and regional environmental inefficiency: Evidence from U.S. states
Halkos, G. E.; Stern, D. I.; Tzeremes, N. G. (2015)We apply a conditional directional distance function allowing multiple exogenous factors to measure environmental performance. We evaluate the air pollution performance levels of U.S. states for the years 1998 and 2008. ... -
Pre-evaluating technical efficiency gains from possible mergers and acquisitions: evidence from Japanese regional banks
Halkos, G. E.; Matousek, R.; Tzeremes, N. G. (2014)This study focuses on bank mergers and acquisitions (M&As) and applies a DEA based procedure that allows us to pre-evaluate technical efficiency gains from possible M&As in the Japanese regional banking sector. This approach ... -
Productivity efficiency and firm size: An empirical analysis of foreign owned companies
Halkos, G. E.; Tzeremes, N. G. (2007)There are various arguments about the impact of firm size on productivity growth. On one hand, it is claimed that large firms could be more efficient in production because they could use more specialized inputs, better ... -
Public sector transparency and countries' environmental performance: A nonparametric analysis
Halkos, G. E.; Tzeremes, N. G. (2014)Based on the theoretical background of the link between countries' public sector transparency and environmental policy, our paper provides empirical evidence for a sample of 49 countries for the time period of 1995-2000. ... -
