Levels of CO2 emissions from electricity generation in the U.S. have changed considerably in the last decade. This development can be attributed to two factors. First, the shale gas revolution has reduced gas prices significantly, leading to a crowding out of the more CO2-intensive coal for...

This paper measures environmental efficiency (EE) and environmental productivity (EP) and analyzes differences in these across countries. It explores the macro-economic factors that could explain these differences and whether these differences can be explained by income levels and by the degree...

We use the non-parametric Data Envelopment Analysis (DEA) and the parametric Stochastic Frontier Analysis (SFA) to workout efficiency and productivity of the ICT sector across 50 countries for the time period 2016 and 2020. By considering OECD -DSTRI index as bad output, the study intends to...

The standard indicators used to compare cross-country innovation are in the Global Competitiveness Report (GCR). But there are problems with aggregation and response bias with these largely self-reported measures (Hollanders and van Cruysen, 2008). We propose a theory-based metric using Data...

This paper uses a panel data set of microfinance institutions (MFI) across the world to compare several identification strategies of cost efficiency and economies of scale. Concretely, we contrast the non-parametric Data Envelopment Analysis (DEA) with the Stochastic Frontier Analysis (SFA) and...

This paper evaluates the efficiency of the twenty-one largest Syndicates of Lloyd's of London. Members of Lloyd's of London are grouped into Syndicates in order to undertake insurance liabilities. In this study, the Syndicate is regarded as the counterpart of an insurance company in a regular...

This paper explore the role of institutions to enhance the productivity growth across countries using a two stage Double Bootstrap Data Envelopment Analysis (DEA). The productivity growth is calculated on the basis of Malmquist productivity index. It also explores the sources of productivity...

The growing complexity and intertwining of different socio-economic issues both in individual countries and internationally mean that single-theme analyses do not consider all the relationships and thus have cognitive limitations. Therefore, studies that combine several research areas are...

We study the United Nations Organization's Kyoto Protocol nations to address two questions. First of all, what are the environmental production efficiency rankings of these nations? Secondly, is there a relationship between a nation's ratification status and its environmental production...
