  1. Methodologies for the Assessment of Socio-Economic Benefits ofWeather, Climate and Water ServicesJeffrey K. LazoSocietal Impacts Program/Research Applications Lab National Center for Atmospheric Research Meeting of the WMO Forum: Social and Economic Applications and Benefits of Weather, Climate and Water ServicesGeneva, CH - April 8, 2013

  2. Overview - Assessment of Socio-Economic Benefits Who What Where When Why How I believe these are necessary conditions for identifying the appropriate “How”

  3. Assessment of Socio-Economic Benefits Why Who What How “… a joint WMO-World Bank authoritative document on methodologies for the assessment of socio-economic benefits of weather, climate and water services.” authoritative document methodologies socio-economic benefits weather, climate and water services

  4. Assessment of Socio-Economic Benefits - Why? • Why? • Sound Bites • Program Justification / Budget Justification • Required for Benefit-Cost Analysis • Decision Making for Program Prioritization • Showing Benefits to Actual or Potential End Users • Understanding Human Behavior • Improving Products and Services to Meet NMHS Objectives of Protecting Lives and Property No economics needed Solid social sciences critical Solid economics needed

  5. Assessment of Socio-Economic Benefits – Who? • Who? • This is directly related to “Why” • National Hydro-Met Services • Private Sector Weather Information Providers • Academic Analysts – Consultants • External Funding Agencies • Who needs to pay for this work? • Option 1: National Hydro-Met Services • Option 2: External Funding Agencies • Option 3: …

  6. Assessment of Socio-Economic Benefits – What? Socio-Economic Values of Weather Services Dissemination and Communication Modeling and Forecasting Perceptions and Interpretation Monitoring and Observation Socio-Economic Outcomes Weather Information Value Chain Weather Decision Making Socio-Economic Impacts of Weather Nat’l Hydro-Met Svcs

  7. Assessment of Socio-Economic Benefits – What? • What? • Economic impacts of weather • Economic impacts of weather enterprise • Socio-economic values of weather information • Socio-economic values of improved weather information

  8. What? Option 1: Economic Impact Analysis “Economic impact” of weather enterprise: • Public Sector Operations and Research $3 B/yr. • Private Sector Weather Industry $3 B/yr. Weather Enterprise $6 B/yr. The “Economic Impact” Argument • $ 9B economic impacts - direct and indirect multipliers • ~20,000 Employees • $ 1B tax revenues Tell this to Congressman Skeptical!!! • Boulder, CO • Norman, OK • State College, PA • Silver Spring / College Park, MD We’ve now interested 4 of the 435 Congressmen!!! http://murphy.house.gov/latest-news/e-news-from-congressman-murphy120/

  9. What? Option 1: Economic Impact Analysis • The Weather Enterprise has: • $ 9B direct and indirect economic impacts • ~20,000 employees • $ 1B tax revenues In Comparison: Wedding Industry (http://weddingindustrystatistics.com/) • 2,500,000 weddings/yr. x ~$25,000/wedding = $62.5B industry Recreational Fishing Industry (http://asafishing.org/facts-figures/studies-and-surveys/sportfishing-in-america/) • $ 48B/yr. retail sales • $115B/yr. economic impacts • 828,000 employment impacts National Park Service (http://home.nps.gov/applications/digest/headline.cfm?type=Announcements&id=13481) • FY 2011(request) $3.14 billon • 21,501 direct employees • 2011 – “National Park Service received 279 million recreation visits and visitors spent $13 billion in local gateway regions. Park visitor spending supported 252,000 mostly local jobs. That spending had a $30 billion benefit to the nation’s economy…” http://www.flyfishinsalt.com/news/recreational-fishing-returns-most-nj-waterways http://county10.com/2013/03/06/yellowstone-national-park-spring-opening-delayed-due-to-sequestration-cuts-to-nps-budgets/ http://www.anenchantedevening.com/dj-services/ http://www.crh.noaa.gov/mpx/?n=dualpol

  10. What? Option 2: Economic Impact of Weather • Dutton (2002) - U.S. GDP 1/3rd sensitive to weather • Lazo et al. (2011*) - U.S. GDP ±1.7% owing to weather variability ($485B/yr.) • Hurricane Sandy (2012) – $62B (http://www.huffingtonpost.com/2012/11/29/sandy-economic-impact-damage_n_2214060.html) • US Drought 2012 - $50B? (http://www.bloomberg.com/news/2012-07-16/worst-in-generation-drought-dims-u-s-farm-economy-hopes.html) • So what does this tell us about the value of the Weather Enterprise? • Indication of economic importance of weather • Suggestion of potential value of weather forecasts Does this answer “the question” and get Congressman Skeptical’s attention? * Lazo, J.K., M. Lawson, P.H. Larsen, and D.M. Waldman. June 2011 “United States Economic Sensitivity to Weather Variability.” Bulletin of the American Meteorological Society. 92.

  11. Option 2: Economic Impact of Weather Lazo et al. 2011- U.S. GDP ±1.7% ($485B/yr.) So What? - Suggestion of potential value of weather forecasts * Lazo, J.K., M. Lawson, P.H. Larsen, and D.M. Waldman. June 2011 “United States Economic Sensitivity to Weather Variability.” Bulletin of the American Meteorological Society. 92.

  12. What? Option 3: “Economic” Analysis – Value of Forecasts Starting to get at societal values created by the weather enterprise Value of current forecasts November 2006 Survey • Sample - 1,465 US Households • Median value = $246/HH/yr. • 114,384,000 HH (U.S. Census Bureau 2008) • Total value of $31.5 billion / year to U.S. HH for all weather forecast services • Net benefit of $26.4B / year • Benefit-cost ratio of 6.2 to 1.0 of all U.S. weather forecast services Lazo, J.K., R.E. Morss, and J.L. Demuth. 2009. “300 Billion Served: Sources, Perceptions, Uses, and Values of Weather Forecasts.” Bulletin of the American Meteorological Society. 90(6):785-798

  13. What? Option 4: Economic Analysis – Value of Improved Forecasts • Objective • evaluate households’ values for improved hurricane forecasts and warnings • Hurricane Forecast Improvement Project (HFIP) • Methods • non-market valuation – conjoint analysis • survey-based valuation • requires qualitative aspects • Modeling and analysis • theory-based • empirical • Results • significant marginal values for improved forecast accuracy - landfall, timing, specificity, etc. • total WTP for from baseline to maximum levels on all attributes was $19.52 per household per year • multiplied times 9,857,371 households = $192,421,599 total annual benefit? • Compared to total program cost of about $200,000,000 over ten years

  14. Assessment of Socio-Economic Benefits – How? • For Whatever Why and for Whomever … • Explanation of methodologies should include “standards” • For instance … possible standards for scientific analysis • Validity • Reliability • Peer reviewable • Theory based • Transparent • Replicable • and need to be replicated - validated

  15. Assessment of Socio-Economic Benefits – How? 3 4 2 1 1. Economic impacts of weather 2. Economic impacts of weather enterprise 3. Socio-economic values of weather information 4. Socio-economic values of improved weather information

  16. Assessment of Socio-Economic Benefits – How? • Is this all about the Value of Information (VOI)? • Only for value of “services” • Even there … not really “valuing” the information itself … • Valuing the changes in outcomes

  17. State of the art in estimating VOI (how much, how good) -- some combination of: • Price- and cost-based derivation • Probabilistic approaches • Bayesian belief networks (Cooke and Kousky, forthcoming) • Expert elicitation • Econometric modeling and estimation • Productivity (for example, agriculture, utility load management, transportation) • Simulation modeling and estimation • Enterprise “innovation” and scenario testing Note – this slide “borrowed” as is from Molly Macauley (RFF) Also - Macauley, M.K. and R. Laxminaryan. 2012. The Value of Information: Methodological Frontiers and New Applications for Realizing Social Benefit (Springer).

  18. Assessment of Socio-Economic Benefits – How? • Valuing the changes in outcomes • Requires identifying and quantifying the “value chain” • As virtually any type of change in outcome is feasible … any type of economic valuation method is potentially relevant! • Therefore is developing a single authoritative “methodology” not judicious?

  19. Assessment of Socio-Economic Benefits – How? • Developing a Taxonomy of Methods • Each method can be characterized by: • Theoretical basis • Strengths and weaknesses • Large body of literature in non-hydro-met applications • Do we need a “Taxonomy of Values” first? • Certain types of values can only be measured using certain methods • This depends on the “signal” those values send

  20. Assessment of Socio-Economic Benefits – How? • Taxonomy of Values • Not value of information but value of changes in outcomes • How relevant is this in value of weather services? Hawkins K (2003) Economic valuation of ecosystem services. University of Minnesota. (online) URL: http://www.frc.state.mn.us/documents/council/landscape/SE%20Landscape/MFRC_Economic_Valuation_EcosystemServices_SE_2003-10-01_Report.pdf

  21. Assessment of Socio-Economic Benefits – How? • Relating “Taxonomy of Values” to “Taxonomy of Methods” • Market versus Non-Market Valuation Methods • Revealed Preference versus Stated Preference Methods • Direct versus Indirect Valuation Methods Lazo, J.K. 2002. “Economic Valuation of Ecosystem Services: Discussion and Application.” Drug and Chemical Toxicology 25(4):349–374.

  22. Assessment of Socio-Economic Benefits – How? • Market versus Non-Market • Direct market: the value of the service/good is the market price the value of a particular service/good directly related to the thing in question • Indirect market valuation: when there are no explicit markets for services (de Groot et al. 2002) • Revealed versus Stated Preference • Revealed preference: measurements are based on observations of actual behavior (Freeman, 2003) • Stated preference: based on statements of preferences or choices indicating preferences

  23. Assessment of Socio-Economic Benefits – How? • Market approaches (all are revealed preference): • Production functions - e.g., crop simulations linked to market data/assumptions • Avoided Cost: services allow society to avoid costs that would have been incurred in the absence of those services • Averting behavior: observed voluntary behavior from individuals used e.g., for health protection or as a substitute for another good or service. • Replacement Cost: cost to replace services with human-made system • Modeling Approaches • Input-output modeling • Computable General Equilibrium (CGE) modeling • Econometric Modeling Lee et al. 2010; Mendelsohn and Olmstead. 2009

  24. Assessment of Socio-Economic Benefits – How? • Non-market approaches (Freeman 2003): • Revealed preference methods • Travel Cost: value measurable by price consumers WTP to travel there • Hedonic Pricing: service/good’s price varies with factors associated to that service or good (Pettler, 2008) • Stated preference methods relying on willingness to pay surveys, • contingent valuation method (CVM) • conjoint/stated choice method

  25. Assessment of Socio-Economic Benefits – How? • Benefits Transfer • Inferring value from studies in other sectors, countries. • Cheaper – but not necessarily good science • Requires a foundation of why these estimates might transfer. • Requires the primary studies for transferring!!!

  26. Assessment of Socio-Economic Benefits – How? • Expert Elicitation • Eliciting subjective estimates from individuals with expertise in area of interest • Developed from approaches for quantification of parameters under “uncertainty” • What is an expert? What constitutes expertise or knowledge? • Total system perspective • Value of communication / through across participants • Current research • World Bank – Mozambique • US – Department of Energy Solar Energy Weather Forecasts

  27. Assessment of Socio-Economic Benefits – How? • Benefit-Cost Analysis (BCA) • Policy tool for project assessment • Comparing stream of benefits and costs over project lifetime • Issues in BCA • Uncertainty in benefits or costs • Sensitivity Analysis • Monte Carlo Analysis • Equity and Distributional Issues • Inter-period Comparisons / Discounting • Choice of functional form and discount rates

  28. Conclusions • Who • What • Where • When • Why • How
