We use nonparametric methods to compute the environmental inefficiency of 100 countries over the period 1990-2017 on the macro-level. The inefficiency is expressed as the potential reduction of GHG emissions, holding economic output constant. Based on that, we estimate different trend functions...

This paper analyses the gold sector's environmentally-adjusted (carbon dioxide – CO 2 emissions) efficiency using cross-sectional global mine-level data from 2019. We use a meta-frontier approach to compute mine level efficiency under different technologies and environments (e.g., open pit vs....

In this paper we concern with the decomposition and aggregation of cost efficiencies when input prices vary across decision-making units. In this respect, we first examine the relations among the components of the existing decompositions as well as with other efficiency measures. We also derive...

To promote the benign development of China's power industry in terms of efficiency improvement and environmental protection, China's power industry needs to ameliorate the market and environmental technical efficiency urgently. Based on the internal mechanism of production-supply in power...

This study used descriptive statistics, budgetary analysis, and stochastic profit function to analyze data collected from 120 catfish fingerlings producers in Edo State, Nigeria to examine the profitability and profit efficiency of their production. Results from the study show that catfish...

The aim of the research was to evaluate wages of wage earners and farmers’ own labor payment based on farm income in terms of various types of farming in Poland. The paper also examines the impact of subsidies on the payment of farmers’ own labor inputs and production efficiency. The...

For most of the second half of the 20th century, modern neoclassical finance, and more generally much of social science, has been based on the von Neumann and Morgenstern (VM) (1944) game theory expected utility axioms as a prescription for rational decision making under uncertainty. Traditional...

Whether input suppliers charge customized (discriminatory) or industry-wide (uniform) prices affects downstream manufacturers' incentives to innovate. This paper investigates the implications of input price discrimination when an upstream monopolist commits to prices before downstream firms make...

As a result of liberalisation of the industrial policy, a number of multi-national companies are being established in the country. With the varying nature of these industries, they generate more wastes resulting in the lower overall productivity. Gradually lot of approaches have been adopted in...
