This paper formulates and estimates a household-level, billing-cycle water demand model under increasing block prices that accounts for the impact of monthly weather variation, the amount of vegetation on the household’s property, and customer-level heterogeneity in demand due to household demographics. The model utilizes US Census data on the distribution of household demographics in the utility’s service territory to recover the impact of these factors on water demand. An index of the amount of vegetation on the household’s property is obtained from NASA satellite data. The household-level demand models are used to compute the distribution of utility-level water demand and revenues for any possible price schedule. Knowledge of the structure of customer-level demand can be used by the utility to design nonlinear pricing plans that achieve competing revenue or water conservation goals, which is crucial for water utilities to manage increasingly uncertain water availability yet still remain financially viable. Knowledge of how these demands differ across customers based on observable household characteristics can allow the utility to reduce the utility-wide revenue or sales risk it faces for any pricing plan. Knowledge of how the structure of demand varies across customers can be used to design personalized (based on observable household demographic characteristics) increasing block price schedules to further reduce the risk the utility faces on a system-wide basis. For the utilities considered, knowledge of the customer-level demographics that predict demand differences across households reduces the uncertainty in the utility’s system-wide revenues from 70 to 96 percent. Further reductions in the uncertainty in the utility’s system-wide revenues in the, range of 5 to 15 percent, are possible by re-designing the utility’s nonlinear price schedules to minimize the revenue risk it faces given the distribution of household-level demand in its service territory.

Health risks from poor malaria control, unsafe water, and indoor air pollution are responsible for an important share of the global disease burden—and they can be addressed by efficacious household health technologies that have existed for decades. However, coverage rates of these products among populations at risk remain disappointingly low. We conducted a review of the medical and public health literatures and found that health considerations alone are rarely sufficient motivation for households to adopt and use these technologies. In light of these findings, we argue that health education and persuasion campaigns by themselves are unlikely to be adequate. Instead, health policymakers and professionals must understand what users value beyond health and possibly reengineer health technologies with these concerns in mind.

Executive summary:

Statoil was founded in 1972 as the national oil company (NOC) of Norway.  Along with Brazil's Petrobras, Statoil today is a leader in several technological areas including operations in deep water.  With its arm's length relationship to the Norwegian government and partially-private ownership, it is generally considered to be among the state-controlled oil companies most similar to an international oil company in governance, business strategy, and performance.

Statoil's development and performance have been intimately connected to its relationship with the Norwegian government over the years.  The "Norwegian Model" of distinguishing Statoil's commercial responsibilities in hydrocarbons from regulatory and policy functions granted to other government bodies has inspired admiration and imitation as the canonical model of good bureaucratic design for a hydrocarbons sector. 

However, the reality is that Norway's comparative success in hydrocarbons development, and that of Statoil, has been about much more than a formula for bureaucratic organization.  Belying the notion of a pristine "Norwegian Model" that unfolded inexorably from a well-designed template, the actual development of Norway's petroleum sector at times was, and often still is, a messy affair rife with conflict and uncertainty.  But Norway had the advantage of entering its oil era with a mature, open democracy as well as bureaucratic institutions with experience regulating other natural resource industries.  Thus far, the diverse political and regulatory institutions governing the petroleum sector-and governing the NOC-have collectively proven robust enough to handle the strains of petroleum development and correct the worst imbalances that have arisen. 

Mark Thurber and Benedicte Tangen Istad make the following six principal observations from their research.

First, Norway's policy orientation from the start was focused on maintaining control over the oil sector, as opposed to simply maximizing revenue.  As a result, the country was more concerned with understanding and mitigating the possible negative ramifications of oil wealth than with any special advantage that could be gained from it. 

Second, the principal means through which Norway was able to exert control over domestic petroleum activities was a skillful bureaucracy operating within a mature and open political system.  Civil servants gained knowledge of petroleum to regulate the sector through systematic efforts to build up their own independent competence, enabling them to productively steer the political discourse on petroleum management after the first commercial oil discovery was made.  Robust contestation between socialist and conservative political parties also helped contribute to a system of oil administration that supported competition (including between multiple Norwegian oil companies as well as international operators) and was able to evolve new checks and balances as needed.

Third, Statoil did play an important role in contributing to the development of Norwegian industry and technological capability, in large part because it had the freedom to take a long-term approach to technology development.  With a strong engineering orientation and few consequences for failure as a fully state-backed company, Statoil developed a culture valuing innovation over development of a lean, commercially-oriented organization.  These priorities may not have always contributed to maximization of government revenues in the short run-costs came to be perceived as high in Norway (for various reasons not all related to Statoil) and Statoil was on occasion responsible for significant overruns.  However, the focus on innovation contributed to significant technological breakthroughs and helped spur the development of a high-value-added domestic industry in oil services.

Fourth, the formal relationship between Statoil and the government has become more arm's-length as Norway's resources and oil expertise have matured.  Under its first CEO, experienced Labour politician Arve Johnsen, Statoil aggressively flexed its political muscles to gain special advantages in licensing and access to acreage.  As domestic resources began to mature, Statoil's leadership (starting with Harald Norvik in 1988, and continuing through the tenures of subsequent CEOs Olav Fjell and Helge Lund) focused more on forging an independent corporate identity and governance structure that would allow the company to compete effectively abroad. 

Fifth, notwithstanding changes in their formal relationship, it has remained impossible to sever the close ties between the Norwegian state and a company with the domestic significance of Statoil.  These residual ties can manifest in various ways, including: 1) the effect on policy decisions of direct personal connections between Statoil leaders and politicians; 2) persistent "Norway-centric" influences on Statoil's strategy even in the larger context of efforts to internationalize; and 3) public pressure from politicians who continue to see themselves as Statoil's masters.  Such pressures can affect large strategic companies, public or private, in any country, but their effect is magnified by Norway's small size and Statoil's importance within it as the largest petroleum developer.

Sixth, Statoil's experience thus far casts doubt upon the conventional wisdom that NOC-NOC connections provide material benefit in opening resource access around the world.  To the extent that such linkages are important, Statoil would seem to be among the best-positioned to benefit from them as both a highly competent producer and a company that might be sympathetic to the needs of resource-rich countries.  However, there are few instances so far where Statoil's status as an NOC has been an obviously decisive factor in unlocking resources that would otherwise be off-limits.

One effect of the new Obama administration's global charm is that America could be let out of the environmental doghouse. The Obama plan to restart the economy is stuffed full of green incentives, and the new president has earned global cheers for his promise to cut the gases that cause global warming. But hope and change are not easy to implement in Washington, and the first big disappointment is likely to come later this year when the world's governments gather in Copenhagen to replace the aging and ineffective Kyoto treaty.

On climate issues America is less a nation than 50 different states, moving wildly at different speeds.

Pundits have been talking down the Copenhagen summit on the theory that the current financial crisis makes 2009 a tough time for governments to focus on costly and distant global goals like protecting the planet. In reality, the greenish tinge on nearly every economic recovery plan, even China's, show that this crisis offers green opportunity. The real reason Copenhagen will be a disappointment is that the new Obama administration can't lead until it first learns what it can actually implement at home. And delivering greenery in the American political system is harder than it looks-even when the same left-leaning party controls both the White House and Congress.

On environmental issues, America is barely a nation. Under a single flag it uneasily accommodates a host of states pushing greenery at wildly different speeds. In the 1970s and 1980s, this multispeed environmentalism propelled America to a leadership position. The key was truly bipartisan legislation, which allowed Washington to craft a coherent national approach. In fact, most of the major U.S. environmental laws did not arise solely from the environmental left but were forged by centrist Republican administrations working closely with centrist and left-leaning Democrats. Republican President Nixon created America's pathbreaking clean air and water regulations; Republican George H.W. Bush updated the air rules to tackle acid rain and other pernicious long-distance pollutants. In his more moderate second term, Ronald Reagan was America's champion of the ozone layer and helped spearhead a treaty-probably the world's most effective international environmental agreement-that earned bipartisan support at home and also pushed reluctant Europeans to regulate the pollutants.

Ever since the middle 1990s-about the time that the U.S. government was shut down due to a partisan budget dispute-such broad coalitions supporting greenery have been rare. In the vacuum of any serious federal policy, for nearly a decade the greener coastal states devised their own rules to cut warming gases. The United States as a whole let its green leadership lapse. (At the same time, the project to create a single European economy has shifted authority in environmental matters from individual member states into the hands of central policymakers in Brussels, where a coterie of hyperrich and very green countries have set the agenda. Europe, long a laggard on environmental issues, is now the world leader.)

The normal multispeed script was playing out on global warming as the Obama administration took power. Industry, worried about the specter of a patchwork of regulations, has lobbied for a coherent national strategy. But the Obama administration's first major policy on global-warming policy went in precisely the opposite direction: he reversed the Bush administration's decision that blocked California from adopting its own strict rules on automobile efficiency.

Today's challenge, which won't be solved by Copenhagen, is for Obama to stitch these many state environmental efforts together. That's no easy task. Global-warming regulation will probably have a larger impact on the nation's economy than any other environmental program in history, and any plan will have to allow enough room for some states to move quickly while also satisfying industry's well-founded need for harmony. Obama's Democratic Party controls both the White House and Congress, but that does not guarantee success. It will be difficult to craft a national policy that earns broad and bipartisan support while also taking the big bite out of the emissions that the rest of the world is hoping Obama will promise to the Copenhagen treaty. The difficulties aren't just in dragging along wary conservative Republicans. In fact, the most important skepticism about an aggressive national strategy has been from a coalition of centrist Democrats who fear the impact on jobs and economic growth.

One key to success will be crafting a deal with China and other developing countries to show that they, too, are making an effort. But serious efforts on that front are still in their infancy.

The big challenge for Copenhagen will be to find a way to allow negotiations to stretch beyond the unrealistic 2009 deadline while still keeping momentum. America's slowness in getting serious about global warming should be welcome because it is a contrast to its rushed behavior in negotiating the Kyoto treaty. At Kyoto, Bill Clinton's administration promised deep cuts in emissions without any plan for selling them at home, which is why the Bush administration could so easily abandon the treaty. Repeating that mistake would be a lot worse than waiting a bit for America to craft real leadership. If that's why Copenhagen falls short of the mark, then that's good news-real greenery, rather than fakery.
