Danish household consumption increased by 58% over the period 1966]1992 while CO2 emissions only increased by 7%. Using decomposition analysis we investigated the global CO impact of Danish household consumption from 1966 to 1992. Our conclusion is that 2 overall growth in private consumption } but not changes in the composition of consumption } is the key to understanding the increase in CO em...
The aerobic bacterial flora in the gut of turbot larvae and their influence on larval survival was examined. Two turbot experiments were run with six replicates each time. Large variation, from 0% up to 44%, was observed in the survival percentage of turbot larvae. There was no correlation between the number of bacteria present in the gut of turbot larvae and the larval survival rate. During bo...
I examine the long-run behavior of oil, coal, and natural gas prices, using up to 127 years of data, and address the following questions: What does over a century of data tell us about the stochastic dynamics of price evolution, and how it should be modeled? Can models of reversion to stochastically fluctuating trend lines help us forecast prices over horizons of 20 years or more? And what do t...
I use daily futures price data to examine the behavior of natural gas and crude oil price volatility in the U.S. since 1990. I test whether there has been a significant trend in volatility, whether there was a short-term increase in volatility during the time of the Enron collapse, and whether natural gas and crude oil price volatilities are interrelated. I also measure the persistence of shock...
1. Neuronal responses to tones and transient stimuli were mapped with microelectrodes in the primary auditory cortex (AI) of barbiturate anesthetized cats. Most of the dorsoventral extent of AI was mapped with multiple-unit recordings in the high-frequency domain (between 5.8 and 26.3 kHz) of all six studied cases. The spatial distributions of 1) sharpness of tuning measured with pure tones and...
Using plant-level data for the Irish manufacturing sector over the period 1983-98, we study the coagglomeration of domestic plants and foreign multinationals in Ireland. To this end we make use of the index developed by Ellison and Glaeser (1997) and find coagglomeration to be important for a number of sectors. We further test for the impact of coagglomeration on domestic firms’ employment grow...
This article reports on a simulation and scenario analysis of Chinese passenger vehicle growth and resulting energy demand and CO2 emissions. The model includes provincial level logistic growth functions with saturation levels representative of neighboring Asian economies, income growth measured in international dollars, and both estimated and literature-based income elasticities. Scenarios exp...
We consider a model of cake-eating with private information. The model captures phenomena such as trust and “security of supply” in resource-use relationships. It also predicts supply shocks as an equilibrium phenomenon: privately informed sellers have incentives to reveal resource scarcity too late, through a supply disruption, after which they exploit the consumers’ inability to immediately a...
Over the past several decades, significant efforts have been made to regulate the use of resource and pollution in most industrialized countries, and the stringency of pollution regulations has continued to increase globally. At the same time, physical and social infrastructures are influenced by changes in the use of resources which contribute to the wealth of many regions. Technical progress ...
This paper contains a dynamic conduct parameter model to look at the pricing behavior of five power marketers in the California Power Exchange (CalPX) on daily data for 2000. Only our previous paper Hodge and Dahl (2012) specifically focused on just the electric power marketers. In this paper we compare a dynamic conduct parameter with that of our earlier static model to test whether the static...
