The analysis of gas emissions by an input-output subsystem approach provides detailed insights into pollution generation in an economy, by revealing the channels by which the environmental burdens are caused and transmitted throughout the production system. In this paper we propose a...

This paper applies the Ijiri–Simon test for systematic deviations from Gibrat's law to citation numbers of economists. It is found that often-cited researchers attract new citation numbers that are disproportionate to the quality of their work. It is also found that this Matthew effect is...

Quantile kernel regression is a flexible way to estimate the percentile of a scholar's quality stratified by a measurable characteristic, without imposing inappropriate assumption about functional form or population distribution. Quantile kernel regression is here applied to identifying the...

A rational, successive g-index is proposed, and applied to economics departments in Ireland. The successive g-index has greater discriminatory power than the successive h-index, and the rational index performs better still. The rational, successive g-index is also more robust to differences in...

A survey of the economic impact of climate change and the marginal damage costs shows that carbon dioxide emissions are a negative externality. The estimated Pigou tax and its growth rate are too low to justify the climate policy targets set by political leaders. A lower discount rate or greater...

The transition from autocracy to democracy may lead a country to break-up. The break-ups of the USSR and Yugoslavia led to sharp falls in emissions. If something similar would happen in China, projected emissions would fall by 50% or more. Break-up uncertainty dominates other scenario uncertainty.

We develop a climate-economy model with active learning. We consider three ways of active learning: improved observations, adding observations from the past and improved theory from climate research. From the model, we find that the decision maker invests a significant amount of money in climate...

Most functions of economic impact assume that climate change is smooth. We here propose impact functions that have stochastic climate change as an input. These functions are identical in shape and have similar parameters as do deterministic impact functions. The mean stochastic impacts are thus...

This paper analyses the medium-term effects of a carbon tax on growth and CO₂ emissions in Ireland, a small open economy. We find that a double dividend exists if the carbon tax revenue is recycled through reduced income taxes. If the revenue is recycled by giving a lump-sum transfer to...
