This paper analyses efficiency drivers of a representative sample of Japanese seaports by means of the two-stage procedure proposed by Simar and Wilson (2007). In the first stage, the technical efficiency of seaports is estimated using several models of data envelopment analysis (DEA) that might...

Data Envelopment Analysis (DEA) techniques are applied to a state-level data set to measure the total factor productivity in US agriculture over 1960-1996. Total factor productivity is decomposed into input and output biased technological change, efficiency change, and scale change, under both...

This paper considers how environmental problems affect economic growth. In order to explain the relationship between the economy and the environment, we impose the law of mass conservation and its corollary, the mass balance principle, and consider pollution from both production and consumption...

R&D policies play an important role for developing technologies. Alternative technology indexes are tested to provide an improved understanding of technology index in the offshore oil and gas industry. The analysis compares ten alternative technology indexes including technology diffusion...

This study evaluates efficiency of forest management in Japan. Our results show that efficiency of forest management decreases over 25 years period from 1975-2000 on average. The study indicates a substantial variation in efficiency across prefectures with a potential for output saving in the...

The creation of an artificial market through a tradable permit system as a remedy against market failure is gaining popularity among analysts and policymakers. We show that in an intertemporal competitive economy, a tradable permit system may not achieve efficiency without setting appropriate...

This paper investigates the effect of shadow price regarding weak sustainability indicators based on the genuine savings indicator. We analyse the forest resources considering positive externalities of natural capital, as the approximation from market rent alone would under-estimate the true...

This study examines the mechanisms of social cost of carbon (SCC) and marginal abatement cost (MAC) in climate change modeling. To examine these mechanisms, we observed the shifts in the marginal benefit (MB) and marginal cost (MC) curves of carbon dioxide (CO<Subscript>2</Subscript>) abatement when parameter values...</subscript>

This paper examines the time-varying levels of weak-form efficiency and the presence of structural breaks for two worldwide crude oil benchmarks over the period spanning from January 2, 1990, through September 18, 2012. We use two different econophysics approaches for comparison purposes. The...
