    • Examines changes in energy intensity by states in the previous two decades
    • Attributed changes to measurable factors and identified portion potentially due to unobserved factors--including state policies
    • Looks at residential, commercial, industrial, and transportation sectors from 1977-1999
    • Factors examined to explain changes in energy intensity include: energy prices, composition of state output, capacity utilization, capital investment and new construction, population and demographics, climate, technological innovation, energy policies
    • RAND regression model includes state fixed effects and an aggregate time trend
    • Energy intensity defined as energy use per dollar of GSP
    • Theoretical models use log of energy intensity as the dependent variable and include both state and year fixed effects
    • Study addresses sectors separately and in aggregate
    • Considered the periods 1977-1988 and 1988-1999 separately because of the much greater energy price stability seen in the latter
    • In the residential sector, the authors found the effects of the following variables to be statistically significant (p<0.05): heating-degree days; cooling-degree days; electricity prices; natural gas prices; disposable income per capita; employment per capita; household size
    • In the commercial sector, the authors found the effects of the following variables to be statistically significant (p<0.05): heating-degree days, cooling-degree days; energy prices; employment per GSP from Services; Commercial GSP from Retail Trade; Commercial GSP from F.I.R.E. and Legal; Commercial GSP from Health
    • In the industrial sector, the authors found the effects of the following variables to be statistically significant (p<0.05): energy prices; percent of industrial GSP from Petroleum, Paper, and Metallurgy; Percent of Industrial GASP from Food, Textile, and Lumber; Percent of Industrial GSP from Mining; Percent of Industrial GSP from Agriculture; Deviation from Equilibrium GSP

      • effects on air emissions
      • effects on households, especially low-income households
    • ceteris paribus, authors find that improvements in energy efficiency are associated with increases in GSP
    • energy efficiency improvements may offer more significant benefits to low-income households since energy expenditures are a higher fraction of their income and since such households tend to be the least energy efficient to begin with

    • Authors propose the chain weighted Fisher Ideal Index as a formula for decomposing aggregate trends in energy intensity into its component changes in economic activity and energy efficiency
    • it does not matter whether the underlying measures of activity can be summed to equal an aggregate measure of activity (e.g. GSP components vs. floor space or passenger miles). Rather, what matters is that intensity, which is analogous to prices in the index number theory, is well defined, i.e. is a "good" measure of the sector level energy intensity
    • Authors apply their Fischer Ideal index approach to the manufacturing sector and found that for 1983-1998, the rate of aggregate electricity intensity change was -0.3%, about half of which was sectoral shift and half was real intensity
    • Authors find that for electricity there was little net change in the eighties, but both structure and intensity factors lead to a decline in electricity intensity in the nineties. The authors suggest that is might indicate a reversal of a historical shift toward electrification [Note: a shift away from electricity would lead to a lower electricity intensity/efficiency without actually requiring improvements in energy intensity/efficiency]
  • Brennan, Timothy J. 1998. "Demand-Side Management Programs Under Retail Electricity Competition." Resources for the Future (RFF) Discussion Paper 99-02.
    • Brennan explains why deregulation and the introduction of competition to electricity markets threatens the viability of DSM programs but also weakens the rationale for having DSM at all
    • Reviews arguments for DSM programs: consumers cannot tell how much energy they will save from certain investments and agency problems (e.g. landlords/tenants, home builders/home buyers)
    • Brennan supposes that competitive electricity markets might lead to creative marketing by firms who will bundle DSM with electricity provision
    • Competition will not eliminate the discrepancy between market prices and true marginal costs of electricity. As such, DSM could still be warranted as a means of getting consumers to choose the level of energy efficiency that they would have selected had they faced the true social marginal cost of electricity
    • Brennan points out that as a "second-best" tool compared to energy taxes, DSM leads to an overconsumption of the services produced with electricity

    • DeCanio performs regression analyses using EPA data from its Green Lights program--a voluntary effort by firms to report on savings from efficient lighting investments
    • Finds that paybacks and IRRs are neither uniform across firms nor close to the risk-adjusted discount rate that would constitute the appropriate "hurdle rate" for investments under conventional investment analysis
    • Data suggest that Green Lights projects are far more profitable than any plausible risk-adjusted cost of capital for comparable projects
    • DeCanio concludes from his regression results that transaction costs cannot explain "energy paradox"

      • energy efficiency resource standards (EERS)
      • combined heat and power (CHP)
      • building energy codes
      • transportation policy
      • appliance and equipment efficiency standards
      • tax incentives
      • state lead by examples and R&D
    • authors claim that data on energy efficiency spending rather than savings have been more accurately tracked now that more programs are run by non-utilities
    • utility spending on energy efficiency declined rapidly as states restructured their electricity markets since utilities were worried about cost recovery
    • ACEEE claims that, after reaching a low point in the late 1990s, energy efficiency spending increased as states realized that restructured markets did not contribute to energy efficiency and under-investment in infrastructure had led to reliability concerns (e.g. 2003 Northeast blackout)
    • in the 1980s and 1990s, utilities ran almost all energy efficiency programs. Following restructuring, many states enacted PBFs and created new organizations or contracted third parties to administer energy efficiency programs. In many states with PBFs, however, the funding is still directed to utilities to administer energy efficiency programs
    • Note on the energy efficiency spending data used for the ACEEE report: looks like they used EIA-861 plus supplemental data from individual states as needed where those states had non-utility energy efficiency programs
    • spot check of ACEEE data showed that their state ee spending does not match my first-cut at the EIA data (off by 100% in some cases)
    • Twelve states have EERS or similar policies: TX, HI, NV, CT, CA, VT, CO, PA, WA, MN, IL, NJ. Some of these states (HI, PA, NV) have Sustainable Energy Portfolio Standards that allow for both renewable and energy efficiency

        • Information-cost barriers
      • DOE has never used its authority to add new products to the federal efficiency standard list, so states have had to take the initiative
      • Between 2002 and 2005, 11 states adopted product energy efficiency standards; although, many of these standards have been pre-empted by the Energy Policy Act (EPAct) of 2005
    • State tax incentives
      • Tax incentives include: direct income tax credits, reduced sales tax on qualified products, and income tax deductions
      • Tax incentives first offered at the state and federal level in the 1970s
      • Rationales for tax incentives:
        • first cost issues
        • risk aversion
        • low visibility in the market (due to low market share)
        • Low importance of energy expenditures for many consumers and firms

    • Author provides a history of US DSM programs

    • Total resource cost of saved energy includes:
      • Measure costs (cost of purchasing and installing energy-efficient product, borne by either utility, customer, or both)
      • Non-measure costs (costs associated with operating a program--e.g. advertising, evaluation, administrative overhead--borne by utility)
      • Eto et al include shareholder incentives (i.e. bonuses, rate-return adjustments, shared-savings, combinations of these) as a non-measure cost
    • Authors found inconsistent reporting of consumer-borne measure costs by utilities
    • Excluding shareholder incentives decreases the simple average for total resource cost of saved energy by about 7%
    • Authors review methodologies employed by utilities to calculate energy savings (tracking database methods, billing analyses, end-use metering)
    • In contrast to free-rider effect, authors discuss participant spillover (energy savings actions taken by participants in addition to those supported by the DSM program) and non-participant spillover (energy savings actions taken by non-participants as a result of the DSM program)
    • Authors found that total resource costs were 3.2 cents/kWh (44% utility-borne measure costs, 31% customer-borne measure costs, and 25% non-measure costs)
    • Least expensive programs were those that were: very large (energy savings or # of customers), older, targeted to normal (not early) replacement of equipment
    • Most expensive programs were: small (in terms of energy savings), newer programs, direct-install programs
    • Authors defend utilities' estimates of energy savings
      • all energy savings estimates included some degree of post-program savings verification

      • direct rebound effects
      • secondary fuel use effects
      • market-clearing price and quantity adjustments or economy-wide effects
      • transformational effects
    • wrt direct rebound effects, authors' review of literature leads them to conclude that increases in efficiency will be partially offset by increases in consumption but will nonetheless result in a net reduction in energy consumption
    • Authors review empirical studies of residential space heating, space cooling, and transportation
      • Space heating take-back of between 10 and 30% of energy savings
      • Space cooling take-back of between 0-50% of energy savings
    • More limited results for residential refrigeration, lighting, and water heating
      • Water heating: 10-40% take-back

    • Direct measurements of take-back effect for industrial and commercial firms are extremely limited
      • 2% for process fuels in industrial facilities
      • 30%+ for lighting
    • Authors summarize: "for the energy sectors of the US economy for which studies are available, we can conclude that estimates of the rebound are very low to moderate. The upper estimates, however, indicate a rebound effect that is not insignificant. Even these upper bound estimates, though, indicate that most or all of any reductions in energy use or carbon emissions are not lost to changes in behavior."
  • Hassett, Kevin and Gilbert Metcalf. 1995. "Energy Tax Credits and Residential Conservation Investment: Evidence from Panel Data." Journal of Public Economics 57: 201-17.
    • Authors seek to explain the "energy paradox" by modeling households' decision to make residential energy efficiency investments as an irreversible investment in the face of uncertainty
    • Authors find that the option value of postponing an energy efficiency investment helps explain low-rate of uptake of such investments even in the face of tax credits for energy efficiency investments
    • Empirical investigation (tax return panel data) shows that tax credits do have a statistically significant effect on energy efficiency decisions
    • Nonetheless, uncertainty and its effect are such that investment in energy efficiency is so low that the effect of tax credits is negligible

    • Horowitz notes that with public energy efficiency programs consumers do not appear to be paying higher energy prices as they would under a system of energy taxes, but they are in fact at some point paying higher prices or taxes in order to fund the energy efficiency programs
  • Horowitz, Marvin. 2004. "Electricity Intensity in the Commercial Sector: Market and Public Program Effects." The Energy Journal 25 (2): 115-137.
    • Horowitz tries to separate the effects of DSM and market transformation public programs on energy intensity in the commercial sector
    • DSM said to include: energy audits, technical training, financial incentives or some combination thereof to those utility customers who purchase or install approved energy efficiency products and services
    • Market transformation said to begin in 1991 with EPA Green Lights program and its successor Energy Star program; author also includes some of DOE's R&D spending on energy efficiency
    • In addition to federal market transformation programs, state public benefits charges fund market transformation programs including those of regional organizations--Northeast Energy Efficiency Partnership (NEEP); the Midwest Energy Efficiency Alliance (MEAA); Southwest Energy Efficiency Project (SWEEP); and the Northwest Energy Efficiency Alliance (NEEA)--and state agencies in CA, NJ, NY, TX, VT, and WI.
    • Horowitz pays attention to specification bias and measurement error in econometric analysis of energy efficiency trends (p. 119)
    • Author uses DSM program data from Form EIA-861 noting that between 1989 and 1997 only utilities with retail sales or resales of more than 120,000 MWh were asked to report DSM data where this limit was raised to 150,000 MWh from 1998 on
    • Overcoming shortcomings in Form EIA-861 data:
      • Author apportioned DSM values to states based on proportion of utilities sales that were in each state
      • Pre-1992 figures were disaggregated based on proportions in 1992
      • Horowitz found an apparent underreporting of DSM savings in later years and used IVs to correct for measurement error
    • Author uses amount of electronic ballast shipments (for high efficiency commercial lighting) he attributes to market transformation programs as a proxy variable for market transformation program activity

    • Author tests for endogeneity of electricity price variable and uses price in final model (not instrument)
    • Horowitz includes as independent variables (among others):
      • natural gas price since it is the closest substitute for commercial sector energy
      • absolute level of GSP since one might presume some economies of scale
    • Horowitz finds 54% realization rate of reported DSM energy savings--i.e. utilities were overstating their actual net energy savings from DSM programs by almost double

    • Authors examined data reported by 10 utilities on their conservation programs to calculate the life-cycle cost of a unit of energy savings
    • Authors estimate that utilities underestimate the life-cycle cost of a "negawatt" by at least a factor of two
      • more accurate measurement of actual energy savings likely to increase cost estimate by 50%
      • fully including all utility admin costs likely to increase cost estimate by 10% to 20%
      • including customer costs and accounting for free riders expected to increase costs by 25% to 50%
    • Authors found that utilities actually faced a much higher cost per "negawatt" than that alleged by proponents of energy efficiency such as Lovins (of the Rocky Mountain Institute) and EPRI because of:
      • overly optimistic assumptions in technical assessments of energy efficiency cost and savings
      • administrative costs for programs
      • diversity of customers' energy use patterns
      • imperfect information and the attraction of customers for whom energy efficiency investments are not cost effective
    • 80% of energy savings came from industrial and commercial customers
    • Authors identified sources of bias in utilities' cost estimates
      • Utilities do not report all relevant costs
        • many types of administrative costs, including measurement and evaluation and overhead are not uniformly tracked or reported
      • Utilities rely on engineering estimates of energy savings rather than ex post audits
        • most utilities in authors' sample report energy savings based upon ex ante engineering estimates
        • energy savings estimates can differ from actual savings because of diversity in customer utilization patterns, changes in these patterns over time, the limited information a utility has about baseline electricity usage and subsequent changes, differences between participants and the "typical customer," and changes in behavior induced by conservation
        • CA required ex post evaluation beginning in 1994
      • Utilities fail to adequately adjust for free riders
        • many utilities simply ignore free riders
        • utilities fail to recognize that free riders may have utilization characteristics different from the customer population as whole such. In fact, free riders are likely to be those customers for whom energy efficiency is most beneficial. This would exacerbate the error introduced by not controlling estimates for free riders
      • Utilities assume excessive life times for energy efficiency investments
        • utilities use a wide range of assumptions for the investment lifetimes of what would appear to be nearly identical efficiency investments
    • customer transaction costs are real costs

        • cost recovery allowed through base rates or a separate charge
      • Request for Proposal (RFP) Model
        • utility or independent system operator (ISO) issues competitive solicitation to acquire energy efficiency from a third party provider to meed demand--typically used to save energy at peak demand
        • recently approved settlement at FERC allows energy efficiency along with load response and distributed generation to participate in the Independent System Operator New England (ISO-NE) Forward Capacity Market (2005, 2006)--so likely too late a development to include in my study

    • Several categories of hidden costs may affect purchase decisions related to energy efficiency:
      • reduced level of energy service
      • irreducible private costs (inconvenience of installing efficient equipment)
      • time and effort needed to learn about, search for, or develop confidence in the performance of new technologies
    • Authors discuss case studies of failures to adopt cost-effective energy-efficiency measures as prima facie evidence of market failures
    •  until the mid- to late-1980s, utility DSM was advocated by environmentalists and energy efficiency proponents. Starting in 1989, several PUCs changed rate-of-return rules to allow utilities to profit from DSM thus making some utilities into DSM advocates. The main opposition to DSM came from industry groups (especially in the Northeast) who were concerned about price increases and cross-subsidization
    • Authors claim that utility DSM programs are good public policy because they open up large markets for better energy technology. DSM programs are sort of like large-scale demonstration programs for energy-efficient technology (this is the market transformation argument)

    • Finds significantly smaller effects on electricity demand from DSM programs (and thus a higher price per "negawatt") than reported by the utilities themselves
    • Reviews DSM evaluation literature and highlights potential reasons for bias in utilities' estimates of DSM energy efficiency gains

  • Lovins, Amory. 1996. "Negawatts: Twelve Transitions, Eight Improvements and One Distraction." Energy Policy 24 (4): 331-343.
    • Lovins argues for why there is an enormous efficiency gap--one that he thinks is largely due to perverse incentives in building design and a lack of integrated system engineering/design
    • Lovins claims that whole-system engineering can yield large energy efficiency gains but also even larger savings from right-sized equipment (in light of improved efficiency) and other benefits (e.g. improved worker productivity from optimized office building lighting and heating/cooling)
    • Perverse incentives - e.g. building designers are rewarded for spending money rather than saving on equipment and energy costs
  • Lovins, Amory. 2005. "More Profit with Less Carbon." Scientific American 293 (3): 74-83.
    • Lovins claims that energy efficiency offers the cheapest way to reduce carbon emissions
    • Lovins reviews barriers to energy efficiency that include the way that energy efficiency opportunities exist in many small areas rather than a few large ones so that people have trouble recognizing and taking advantage of them
    • Discusses importance of whole system optimization in design--e.g. optimizing the combination of insulation and heating/cooling equipment rather than adding the cost-effective insulation given the heating/cooling equipment
    • Notes importance of rewarding desired outcomes in the case of paying architects and builders for saving money on energy consumption rather than rewarding expenditures on materials

    • Attempts to decompose the changes in energy intensity due to energy efficiency (defined as energy per unit of sector-specific economic activity) and changes in the composition of economic activity using a Fisher ideal index number methodology
    • Metcalf claims his paper is the only analysis of energy intensity changes at the state-level that uses a perfect decomposition method
    • Attributes between 2/3 and 3/4 of decline in energy intensity since 1970 to improvements in energy efficiency
    • Describes the arguments for and against various energy efficiency policies--e.g. the efficiency losses from applying Procrustean standards to heterogeneous consumers/firms and the behavioral responses (e.g. free-riding, rebound effect) that diminish energy efficiency policies' impact
    • Highlights that energy intensity has been declining consistently since 1960 but that the rate was higher in the 1970's and 1980's following the oil crises. In addition, the energy intensity of states has taken on a greater variance over the years with some states reducing intensity greatly and others not at all

    • Describes "energy paradox" claim--i.e. that consumers require excessive rates of return before making energy efficiency investments
    • Lists tax provisions related to energy efficiency
  • Metcalf, Gilbert. 2008. "An Empirical Analysis of Energy Intensity and Its Determinants at the State Level." The Energy Journal 29 (3). Forthcoming.
    • Efficiency refers to the reduced energy use per unit of economic activity within a particular sector (e.g. industrial sector) while activity refers to the changing mix of economic activity (shift from energy intensive economic activity towards non-energy intensive economic activity) holding efficiency constant
    • To carry out this analysis, I analyze a data set on energy consumption at the state-level data between 1970 and 2001. I undertake an econometric analysis of the drivers of changes in energy intensity, efficiency, and activity at the state level. I find that rising per capita income and higher energy prices contribute to declines in energy intensity, primarily through improvements in energy efficiency.
    • Boyd and Roop (2004) first used a Fisher Ideal index as the basis for an exact decomposition of changes in energy intensity
      into changes in energy efficiency and economic activity
    • Because of the lagged dependent variable, standard fixed effect regression procedures will produce biased estimates. I report estimates for the intensity index regression using the Arellano and Bond (1991) estimator

    • utilities face economic incentives to overestimate the impact of their conservation efforts; nonetheless, the authors found no evidence of this in their econometric analysis
    • specifically, regulated utilities that can recover costs of DSM have an incentive to invest in programs with high ex ante conservation impacts but low ex post effects
    • factors that make it difficult to trust utilities reported DSM energy savings:
      • the difficulty of separating utilities' impacts from other forces (e.g. free-ridership, market transformation, take-back and price responses)
      • Overestimation:
        • utilities' incentive to overestimate conservation impacts
        • technical phenomena: improper installation or operation of equipment, inaccurate equipment operating profiles, mistreatment of equipment interactions
        • free-ridership
        • take-back
      • Underestimation
        • market transformation - indirect effects of conservation programs in changing the market availability of efficient equipment and affecting public attitudes toward conservation
    • study looked at reported conservation savings from a sample of 39 utilities in the Northeast and CA for the commercial and industrial sectors from program inception through 1993
      • unit of observation was utility service area
      • model used first differences approach to predict changes in electricity demand rather than absolute level
      • variables included beyond mine were fuel oil and coal prices
      • authors calculate electricity price the same way that I do, and they note that it is an imprecise proxy for actual electricity pricing since it includes miscellaneous charges not directly related to electricity consumption (i.e. it's not the true marginal price)
      • authors multiplied cooling degree days by a linear time variable to reflect the long-term increase in AC equipment penetration
      • reported conservation savings were an independent variable so the coefficient on this term is the % of reported savings actually realized, and the estimated coefficient for all utilities is -0.994
      • authors conclude that there is no systematic bias in utilities' reporting of DSM impacts
      • limitations: small sample, commercial and industrial only, no data on expenditures
      • authors did not trust the EIA-861 data after spot checking it and so went directly to the utilities and PUCs
    • authors report that utilities have improved their estimates of net conservation by using customer surveys, market studies, statistical analyses of billing records, and other techniques

    • Authors look at 19 subsectors in the German commercial and services sectors and conduct Logit regressions to identify factors that affect the likelihood of adopting energy efficiency measures
    • Data for regressions come from a survey of ~2800 companies and public institutions
    • Authors review barriers to energy efficiency as found in the literature:
      • information and other transaction costs
      • bounded rationality (use of routine or rules of thumb)
      • capital constraints (particularly in public sector where entities cannot borrow)
      • uncertainty and risk (stochastic energy prices and option value of postponing ee investments)
      • investor/user dilemma
        • bias towards projects with short-payback despite inferior NPV because of short tenure of agents
        • lack of department accountability for energy costs
        • separate, nonfungible budets for capital and operating costs
    • Survey involved asking interviewees if they had adopted any of a range of energy saving measures, and interviewees were asked to rate the importance of potential barriers to energy efficiency
    • Logit models based on dichotomous dependent variable equal to one for entities that had implemented at least 50% of the feasible energy saving measures based on the survey data
    • Authors found that barriers varied considerably across subsectors with two or three variables usually statistically significant but without any clear pattern
    • Rented independent variable was significant in more than half of the models which the authors take to be support for the investor/user dilemma

    • Author contrasts mainstream economic cost-benefit analyses of energy efficiency investments with the "free lunch" arguments proposed by adherents to the "energy conservation paradigm"
    • Sutherland criticizes energy efficiency proponents for failing to differentiate between actual market failures and other impediments to investments in energy efficiency
    • Some market barriers touted by energy efficiency proponents are really just the costs of market adjustments, which do not represent actual economic inefficiencies
    • Sutherland criticizes the use of below-market discount rates when estimating the benefits from energy saved
    • Author notes that empirical evidence shows that higher income households demonstrate lower discount rates
    • Author argues that "high discount rates do not reflect irrational decisions and market inefficiencies. Instead, high discount rates are efficient and rational when investments are risky, require sunk costs and can be delayed and considered at a later date"
    • A rebate provides a larger benefit to free riders than to new adopters. Rebates to free riders are merely a redistribution of wealth.
    • Tax credits to promote energy efficiency may have adverse equity effects since most participants in residential energy conservation programs are from higher income classes. However, the cost of such programs is paid for by all classes, and energy costs are a larger share of the incomes of lower income classes.

  • Vine, Edward et al. 2003. "Public Policy Analysis of Energy Efficiency and Load Management in Changing Electricity Businesses." Energy Policy 31: 405-430.
    • Examines impacts of generic electric industry models (e.g. vertically integrated monopoly, unbundled monopoly, unbundled full competition) on energy efficiency and load management
      • Commercialization - utilities have an incentive to improve energy efficiency only up until the customer's meter
      • Privatization - when ownership of a utility shifts from the public to private sector, the utility will likely use a higher discount rate when assessing projects thus rejecting some energy efficiency investments that a public utility would not
      • The "wires" businesses may have incentives to promote energy efficiency to avoid bottlenecks, but they may lack customer relationships
      • Competition - if end-users see only short-term generations costs, they are less likely to engage in energy efficiency investments since short-term costs are uncertain. Moreover, electricity providers have little incentive to invest in energy efficiency if doing so means raising rates for non-captive customers
    • Includes extensive lists of policy and program barriers as well as how they are addressed by various mechanisms (i.e. control, funding, support, and market mechanisms)
      • Control mechanisms include: mandatory sourcing of energy efficiency, integrated resource planning (IRP)
      • Funding mechanisms include: PBFs
      • Support mechanisms include: developing the ESCO industry, voluntary agreements
      • Market mechanisms include: taxes on energy, tax credits for energy efficiency investments, demand-side bidding in wholesale markets
    • Interesting factors to consider for thesis: wholesale markets' allowance of demand-side resource bidding
  • Wing, Ian Sue. 2007. "Explaining the Declining Energy Intensity of the U.S. Economy." In Press. Resource and Energy Economics.
    • Econometric study of energy intensity from 1958-2000
    • Author finds that changes in the sectoral composition of the economy was the main driver behind energy intensity
    • Among the intra-industry forces, disembodied exogenous technical progress is the predominant energy-saving influence
    • Until 1973, most of the reduction in energy intensity was due to changes in the sectoral composition of the economy whereas industries were actually increasing their energy intensities.
    • After the first OPEC oil shock, the effects of structural changes diminished and instra-industry efficiency increased
    • The influence of technical change is very slightly energy-using prior to 1980 and energy-saving thereafter
    • Declining energy intensity within industries is largely due to energy demand from vehicle stocks

    • Wirl uses a theoretical, economic framework to explain why DSM programs will face significant challenges in delivering actual energy savings due to principal-agent slippage (driven by consumers' private information) and the regulatory incentives utilities face which lead them to select inefficient DSM programs
  • Wirl, Franz. 1999. "Conservation Incentives for Consumers." Journal of Regulatory Economics 15 (1): 23-40.
    • using theoretical approach, Wirl identifies the optimal design for energy conservation incentives in light of customers' strategic reactions and utilities' imperfect information
    • Wirl criticizes much of the literature on DSM for overlooking the strategic behavior on the part of consumers that private information induces
    • Wirl concludes that, given his assumptions, the optimal DSM program will actually subsidize the most efficient consumers--since it is costly to masquerade as high efficiency
    • Wirl assumes the existence of two market failures commonly used to justify DSM programs--namely, the observation of too short payback times (i.e. too high discount rates) and prices for electricity that are below the marginal cost of production
