Topic: Booms, Busts and Natural Resource Curses: Economic Effects of Energy Development in the West
Abstract: The recent boom in domestic energy development has cast renewed attention on western energy boomtowns, and questions about the short and long run economic impacts of oil and gas drilling on local communities have resurfaced. Bodies of literature suggest that these communities may be cursed with slower income growth in the long run, and that local labor will capture few economic gains. We study the oil drilling boom-and-bust cycle during the 1970s and 1980s to gain insights on these questions. Using county-level panel data of drilling and economic outcome variables from 1969 to 2000, we find evidence of positive labor market spillovers to non-energy sectors along with significant increases in earnings, employment, and income during the boom. After the bust, there is little evidence of positive long-term economic growth. Additionally, we find that unemployment compensation in the boom-and-bust counties spiked upward immediately with the mid-1980s bust and stayed high relative to non-boom counties through 2000.

Topic: U.S. State Fiscal Policy and Natural Resources
Abstract: An analytical framework predicts that, in response to an exogenous increase in resource-based government revenue, a benevolent government will partially substitute away from taxing income, increase spending and save. 43 years of U.S. state-level data are consistent with this theory. A fixed-effects model suggests that a 1% point increase in resource revenue results in a .25% point decrease in non-resource revenue, a .45% point increase in government expenditures and a .30% point increase in public savings. These results are largely robust to instrumentation, the omission of outliers and lagging explanatory variables. Interacting resource revenue with state political leanings indicates that democratic governments spend and save more resource revenue than do their republican counterparts. More generally, this paper illustrates the important role that natural resources play in shaping state fiscal policy.

Topic: Strategic Behavior in Smart Markets with Avoidable Fixed Costs
Abstract: Previous research of complex-offer auctions designed for deregulated electricity markets finds that offer complexity allows a great deal of strategic behavior, which consequently leads to anti-competitive and inefficient outcomes. In smart markets that employ complex-offer auctions, the sellers submit not only quantities and minimum prices at which they are willing to sell, but also start-up fees that are designed to reimburse the fixed costs of electric power generators. Using an experimental approach, he compares the performance of two complex-offer auctions against the performance of a simple-offer auction, in which the sellers have to recover all their generation costs – variable and fixed – through a uniform market-clearing price. He finds that the simple-offer auction significantly reduces consumer prices and lowers price volatility. It also mitigates anti-competitive effects that are present in complex-offer auctions and achieves allocative efficiency more quickly.

Topic: Overlapping Environmental Policies: When Does Renewable Electricity Reduce Pollution?
Abstract: Policies designed to expand renewable electricity generation (or reduce electricity demand) have become commonplace. Frequently, renewables and energy conservation are being supported in regions with overlapping environmental regulations such as cap-and-trade as well as Renewable Portfolio Standards. Previous studies demonstrate that once a cap has been placed on the aggregate emissions of a pollutant, a renewable subsidy results in higher abatement costs with no additional abatement. However, the literature exploring interactions between multiple policy instruments has largely abstracted from the fact that the electricity sector produces a wide variety of pollutants, many of which are not subject to a cap. In this paper, it is analytically demonstrated that once a binding cap has been placed on a subset of pollutants, increases in renewable electricity not only offset zero units of the capped pollutants, they can actually increase the aggregate emissions of the uncapped pollutants. Using data on the hourly generation and emissions of CO2 and NOx from the EPA’s NOx cap-and-trade program (CAIR), I provide evidence that increases in renewable electricity are in fact causing CO2 emissions to increase. In settings where regulators are unable to optimally regulate each pollutant, results suggest that efficiency gains can be achieved by combining subsidies for renewables (or energy conservation) with emissions taxes, as opposed to emissions caps.

Topic: Optimal Carbon Taxes with Non-Constant Time preference
Abstract: The paper derives an explicit formula for the near-term carbon price in a dynamic stochastic general equilibrium climate model in which agents employ arbitrary non-constant time preference rates. The paper uses a simplified version of the model in Golosov et al. (2011), though we argue that the added assumptions are unlikely to matter for our conclusions. The formula is derived first under the assumption that the initial decision-maker has a commitment device, then solving for the unique subgame perfect equilibrium. Somewhat remarkably, the near-term carbon price is the same in both cases. We further show that the near-term carbon price remains unchanged for all potential beliefs about the time preference structure of future generations. It follows that concerns about time inconsistency can be safely ignored when applying the derived formula. The carbon price is the same as the Pigouvian tax in the equilibrium with commitment, and it is bigger than the Pigouvian tax in the equilibrium without commitment provided damages are sufficiently persistent. The formula reduces to the carbon price formula in Golosov et al. (2011) when discounting is constant, and it reduces to the carbon price formula in Gerlagh and Liski (2012) when discounting is quasi-hyperbolic.

Topic: Power to Choose? An Analysis of Choice Frictions in the Residential Electricity Market
Abstract: This paper studies the size and consequence of consumer inertia in a setting where retail choice is first permitted. Retail choice has been an important feature of the deregulation of many formerly regulated markets such as long-distance telecom, electricity, and natural gas. The expansion of con- sumer choice has been touted as a means to allow consumers to pay more competitive prices and enjoy more value-added services. However, choice frictions can diminish the benefits of retail choice. We use household-level data for the first four years of residential electric choice in Texas to study the choices of consumers. We find that the majority of customers continued to purchase from the in- cumbent despite large potential monetary savings from switching. We develop an econometric model that allows us to distinguish between three different sources of this observed inertial behavior – (1) inattention due to status quo bias, (2) an incumbent brand advantage, and (3) switching costs. We find that the incumbent enjoys a “brand” effect that provides it with a market share advantage even when lower-priced newcomers enter the market. However, the incumbent’s brand advantage appears to diminish over time. We also find that search and switching costs are important; only a fraction of households actively consider their options each month, and those who do consider other options are face switching costs. We use our choice parameter estimates to conduct a policy counterfactual experiment that informs consumers about the ability to choose and the nature of their options, and we find that such an information treatment could yield notable consumer surplus gains. Our findings have implications for the design of new markets when consumers are provided with choice.

Topic: Measuring the Effects of Natural Gas Pipeline Constraints on Regional Pricing and Market Integration
Abstract: Natural gas markets in the United States depend on an extensive net- work of pipelines to transport gas from production fields to consumers. While these pipelines are essential for the operation of natural gas markets, their capacity sets a physical limit on the quantity of gas that can be moved between regions. Taking advantage of a rich data set of daily pipeline capacities and flows, this paper directly examines the effects of binding pipeline constraints. Constraints significantly increase realized citygate prices in both the Florida and Southern California markets. Cointegration between hub and distant market holds when pipeline flows are not constrained, and break down during constrained periods. Cointegration techniques may not identify bottlenecks between regions when bottlenecks are mild, or when they only occur for limited periods of time. Contrary to earlier results, Southern California and Rockies markets are found to be integrated with the national market. Cointegration tests using data from 14 market points support the notion that wholesale natural gas markets in the United States are generally integrated into a national market.

Topic: Could Subsidy Labeling be Counter productive: Winter Fuel Payment and Energy Decisions
Abstract: The Winter Fuel Payment (WFP) is the main policy of the UK governments attempt to reduce winter morbidity and mortality in older UK households. Previous research, Beatty et.al. (2011) has shown that older households spend a much high percentage of the WFP on heating and electricity than other transfers that do not have the word “fuel” in the title. This labeling effect, generally explained with behavioral economics principles, could be counter productive to energy policy if the labeling discourages households from investing in household insulation or renewable energy. Utilizing the sharp eligibility criteria for the WFP, this analysis shows that households in receipt of the WFP are statistically more likely to install renewable energy technologies but statistically less likely to improve the energy efficiency of their homes.

Topic: Dynamic Salience and Intermittent Price Signals: Theory and Evidence from Smart Electricity Meters
Abstract: In neoclassical demand theory, the cost of consumption is known at the time choices are made. For many goods, however, expenditure is only “experienced” intermittently while choice occurs at greater frequency. Electricity and water consumption are important examples, but digital tracking has made intermittent billing more commonplace for goods such as toll road access, software downloads, apps and games. Yet we know surprisingly little about how these payment patterns affect decisions. This paper exploits hourly household electricity consumption data collected by “smart” electricity meters to examine consumer behavior under intermittent cost signals, and explores the implications for en- ergy pricing and conservation. We develop a simple dynamic model with time-varying price salience which predicts that households adjust consumption in periods soon after a price reminder but even- tually revert to habit as price salience fades. We find statistically significant but economically small daily responses to monthly bills. The responses are also asymmetric; lower bills (negative bill shocks) raise subsequent consumption by significantly more than higher bills (positive bill shocks) reduce consumption. These results confirm that price salience is important in consumption deci- sions, but raise questions about the long-term conservation impact of information-based interven- tions.

Topic: Automaker Responses to CAFE Standards
Abstract: With the latest round of 2017-2025 Corporate Average Fuel Economy standards, the United States is committed to using standards as the policy instrument to reduce oil consumption and emissions. Yet standards are controversial and their effects on automaker decision-making remain an open question. This paper examines the automaker response to changing CAFE standards and gasoline prices using detailed data on vehicle characteristics 1960-2010. We quantify the tradeoff posed by CAFE standards between fuel economy and desirable vehicle characteristics such as weight and horsepower. We find evidence of an automaker response on several margins: the fuel economy of existing models, the introduction of new models, the dropping of older models, and the pricing of vehicles. We also show that there are clear competitive effects of CAFE. These results clarify how CAFE standards actu- ally work to improve fuel economy and what the implicit tradeoffs from implementing such a policy are.

Topic: Market Failure or Reporting Failure? An Analysis of the Drivers of Variation in the Installed Cost of Residential Photovoltaic Systems
Abstract: The U.S. market for residential and commercial photovoltaic (PV) systems has expanded rapidly in recent years, growing from just over 300 MW of installed PV capacity in 2006 to over 2,800 MW in 2011. This rapid growth in the PV market has been fueled largely by a concurrent decline in the installed cost of PV systems. However, despite this rapid and consistent decline in the average reported cost of PV systems and components, variation in reported PV costs has remained quite large, and by some measures, has even increased, challenging the assumption that the U.S. market for PV has achieved maturity. This study uses an econometric approach to explore what factors are driving this continued variation in the reported costs of residential rooftop PV systems installed in California under the California Solar Initiative (CSI) from 2007 through June 2012. Our findings demonstrate that for majority of systems analyzed, costs were driven by the suite of expected drivers, namely system capacity, system efficiency, module price and labor rate. However, we also found preliminary evidence that installers are participating in non-marginal pricing potentially suggesting a market failure in the California residential PV market.

Topic: Algorithms for Incremental Facility Location Problems
Abstract: The study involves two algorithms for the facility location problem in an incremental setting. These are problems arising in the design and planning of optical access networks. We first study a 8-competitive algorithm for an uncapacitated facility location problem. The algorithm provides a sequence of facilities and customers along with their assignments, which is competitive at every point of the sequence. We then study a branch-and-cut algorithm for an incremental connected facility location problem. We study some valid inequalities, complexity of the separation problem, separation heuristics and methods to strengthen them using sequential lifting. We finally present some computational results.

Topic: Maximum Flow with Minimum Number of Labels (MF-ML)
Abstract: The Maximum Flow Problem is one of the most studied and well applied problems in the last decades. It is important both for its practical applications and since it arises as a subproblem for more complex optimization problems (e.g., min cost flow, matching, covering on bipartite graphs). We have introduced a new problem, namely Maximum Flow with Minimum Number of Labels (MF-ML). The problem consists in finding, on an edge labeled graphs, the maximum flow solution that minimizes the number of different labels. MF-ML belongs to the class of problems defined on labeled (colored) graphs, which has met a growing interest in the last decade. Labeled graphs are used to model situations where it is necessary to represent qualitative differences among different regions of the graph itself. Typically, each label represent a different property (or set of properties) to model. This variant finds its real application in telecommunication, transportation and computer networks among the others.
