This study uses microeconomic data from the transportation systems of land cargo in Colombia: rail and trucking, to determine their degree of allocative efficiency through the non-parametric method Data Envelopment Analysis DEA. The average overall efficiency found was 74.4% for trains and...

These comments cover key aspects of Smith's paper. They focus on problems of awarding a central role to carbon taxes, and extend the discussion to harnessing the power of property rights via tradable permits.

Using a production frontier approach, this paper examines the sources of total factor productivity growth in burkinabe cotton farms. The outcomes show deterioration in total factor productivity growth of 0.40 % over the study period, which is mainly due to the decline of technical efficiency...

Most studies on measuring China's energy efficiency were conducted in the framework of the input-oriented Data Envelopment Analysis. This approach generally calculates the technical efficiency by shrinking all the input factors equally proportionally subject to the observed output still being...

Once tea was the major source of export earnings for India, but now India is trailing behind in the field of tea production and exports. Darjeeling tea is considered as India’s pride and almost entire production are exported. The depressed tea export of India actually caused the breakdown...

This study aims to assess the Cost Efficiency (CE) of the Greek cooperative banks over the period 2000–2005. We first use Data Envelopment Analysis (DEA) to estimate the technical, allocative and cost efficiency for each bank in sample. Then, we use a bootstrapping censored (Tobit)...

We develop a tractable dynamic general equilibrium model of oligopolistic competition with a continuum of heterogeneous industries. Industries are exposed to aggregate and industry-specific productivity shocks. Firms in each industry set value-maximizing state-contingent markups, taking as given...

The paper introduces a new dynamic frontier model that is used to analyze the impact of both ownership and regulation on airport technical and allocative efficiencies. We differentiate between the short and long-term effects. Based on a large sample of international airports, we find in the...

The concept of efficiency in groups postulates that a coalition of firms has to record a smaller distance toward the aggregate technology frontier compared with the sum of individual distances. Efficiency analysis (either allocative or technical) is defined with respect to cooperative firm game...
