Not All Regions Are Alike: Evaluating the Effect of Oil Price Shocks on Local and Aggregate Economies

June 6, 2018

Using a sample of 48 contiguous U.S. states for the period 1973-2013, we study how oil price shocks influence state-level economic growth. The analysis incorporates (1) a structural decomposition of the supply and demand factors that drive the real price of crude oil; (2) heterogeneity of states in terms of their production and consumption of […]

A Pocket Full of PIMs

May 15, 2018

By Michael Roberts In the arcane parlance of utility regulation, PIMs are “Performance Incentive Mechanisms.” This is where we’re headed because, slightly against my expectation, Governor Ige recently signed SB 2939, a bill unanimously passed by the legislature that requires that the Public Utilities Commission: “…establish performance incentives and penalty mechanisms that directly tie an […]

Variable Pricing and the Cost of Renewable Energy

May 14, 2018

On a levelized-cost basis, solar and wind power generation are now competitive with fossil fuels, and still falling. But supply of these renewable resources is variable and intermittent, unlike traditional power plants. As a result, the cost of using flat retail pricing instead of dynamic, marginal-cost pricing–long supported by economists–will grow. We evaluate the potential […]

Should regulators fear bond-rating agencies?

April 23, 2018

By Michael Roberts It seems that our political and administrative leaders worry about the bond rating agencies. Their fear is understandable. The cost of capital looms large in all manner of infrastructure projects, and the cost of that capital depends on how risky investors perceive repayment to be. The cost of capital also looms large […]

What a Difference a Rate Makes

May 3, 2016

By Michael Roberts UHERO’s Energy Planning and Policy Group has been writing about how variable pricing of electricity, both wholesale and retail, can lower the cost of intermittent renewables. Get the rates right, and facilitate easy open-access to the grid for both buyers and sellers, and amazing things can happen. The idea is that variable […]

Incentives for the Utility

February 26, 2016

By Michael Roberts *This post follows up on two previous installments in the Sustainable Energy Blog Series: Embrace Policy Experiments for Demand Response and Four Years to Improve Renewable Energy. Perhaps the greatest obstacle to a renewable-energy future is that our utility, Hawaiian Electric Industries (HEI), has little or no incentive to transform its operation into a […]

Embrace Policy Experiments for Demand Response

February 25, 2016

By Michael Roberts *This post follows up on the previous post in the Sustainable Energy Blog Series: Four Years to Improve Renewable Energy. HECO has recently proposed new time-of-use rates and is developing pricing for various kinds of demand response programs.  The proposed programs are a long ways from the open-access, marginal-cost pricing, but they […]

Four Years to Improve Renewable Energy

February 24, 2016

By Michael Roberts Without the debt-ceiling hijinks of earlier years, the federal budget bill passed at the end of last year with a lot less drama and press coverage. But little news turned out to be good news, at least for Hawai`i and renewable energy interests. The spending bill included an extension of the 30% […]
