Energy security is the ability of households, businesses, and government to accommodate disruptions in supply in energy markets. This survey considers the economic dimensions of energy security, political and other non-economic security concerns and discusses policy approaches that could enhance...

We examine the environmental impact of the post-2005 natural gas glut in the United States due to the shale gas boom. Our focus is on quantifying short-term coal-to-gas switching decisions by different types of electric power plants in response to changes in the relative price of the two fuels....

Restructuring electricity markets has enabled wholesalers to exercise market power. Using a common method of measuring competitive behavior in these markets, several studies have found substantial inefficiencies. This method overstates actual welfare loss by ignoring production constraints that...

In electricity markets, generators are rewarded both for providing energy and for enabling grid reliability. The two functions are compensated with two separate payments: energy market payments and ancillary services market payments. We provide evidence of changes in the generation mix in the...

Most US consumers are charged a near-constant retail price for electricity, despite substantial hourly variation in the wholesale market price. The Smart Grid is a set of emerging technologies that, among other effects, will facilitate "real-time pricing" for electricity and increase price...

Squaring hourly demand and wind-solar production data for Germany and a number of neighbouring countries with the results of the EU's ESTORAGE project, this paper studies the limits of Germany's energy revolution in view of the volatility of wind and solar power. In addition to pumped storage,...

We analyze optimal policy when consumers of energy-using durables undervalue energy costs relative to their private optima. First, there is an Internality Dividend from Externality Taxes: aside from reducing externalities, they also offset distortions from underinvestment in energy efficiency....

To reliably achieve deep decarbonization of the US power sector, a candidate policy must perform robustly across a range of possible future trajectories of demand, fossil fuel prices, and prices of new wind and solar capacity. Using a modified version of the NREL ReEDS model with scenarios that...

The transition of Hong Kong's main economic activities from manufacturing to services is accompanied by gradual changes in the regulatory regimes for monopolies. The local telecommunication services industry has been liberalized, deregulation of public transport is taking shape, and the schemes...

U.S. inflation data exhibit two notable spikes into the double-digit range in 1973-1974 and again in 1978-1980. The well-known quot;supply-shockquot; explanation attributes both spikes to large food and energy shocks plus, in the case of 1973-1974, the removal of price controls. Yet critics of...
