Ongoing changes in the US electricity market include restructuring and increased competition. With this unfettering of the market, the fuel choice in generation is expected to become more flexible and responsive. To investigate this hypothesis, studies of US electricity fuel choices over the...

We present a simple mathematical model for the Twitter dynamics, and use the model to extract the information-sharing tendencies on two time scales, day and hour, about three contenders in the 2012 presidential election in South Korea. Comparison of the model results with actual data...

This survey of surveys contains an historical summary of what I knew about short- and long-run gasoline demand elasticities as of 2006. I discuss 13 surveys published from 1977-2004 along with a few additional studies. Although there is wide variation in price and income elasticities across the...

Today, a confluence of factors, such as growing concerns about associated consumption externalities and socioeconomic pressures, is building the momentum towards reducing fossil fuel consumption for road transport and rationalizing prices to reflect direct, indirect and externality costs. While...

Various studies have examined whether market power abuses by independent electricity generators contributed to the demise of the California Power Exchange (PX). However, the behavior of wholesale power marketers has generally been overlooked. To fill this gap, our paper focuses on the pricing...

Gasoline demand, which represents almost a quarter of world petroleum consumption, has been the focus of a considerable amount of econometric work since the 1973 oil embargo. However, researchers and policymakers when considering this work are confronted with a bewildering array of elasticities...

With NEMS, there has been increased interest in modeling energy markets and a resurgent interest in energy elasticities of demand. Since such elasticities are often a convenient way to summarize the responsiveness of demand to such things as own prices, cross prices, income, or other relevant...
