High unemployment, the Gulf oil spill, and mounting fiscal worries clouded our July 4th celebrations. Yet, one patriotic highlight in President Obama's first year was bipartisan support of the Serve America Act, which expanded opportunities for Americans of all ages to meet urgent domestic challenges through community and national service. In the process, Americans who otherwise would have been unemployed are engaging in productive work, at low cost to taxpayers, to meet problems like the high school dropout epidemic. Similar efforts can expand volunteer service abroad.

As President Obama made clear in his first major policy speech to the international community in Cairo, Egypt, the world must unleash its collective imagination through social innovators, entrepreneurs and citizen diplomats to contribute to global development, respond to natural disasters, and initiate interfaith action to tackle preventable diseases like malaria. The moment is now.

Fifty years after John F. Kennedy's call for a Peace Corps, we might reconsider our obligations to meet needs around the world. President Kennedy said that the Peace Corps would be serious when 100,000 Americans were serving abroad each year. Although the Peace Corps is America's flagship international service program, today less than 8,000 volunteers are spread across 77 countries. Since 1961, America has sent and returned nearly 200,000 volunteers, a number significantly less than the millions Kennedy envisioned by his Peace Corps' 50th year. Had the Peace Corps grown at the rate Kennedy envisioned, the course of our country's foreign policy, diplomatic strategy and global awareness over the past 50 years would be very different.

Last week, ServiceWorld, an international service coalition of more than 300 non-profits, colleges, corporations and faith-based institutions, released a bold plan to meet President Kennedy's goal of mobilizing 100,000 Americans every year - and one million over a decade - to serve abroad. The proposed Sargent Shriver International Service Act calls for doubling Peace Corps to 15,000 by 2015, lowering costs per volunteer, and forging partnerships with the hundreds of non-profits that have emerged since its creation. Doubling of the Peace Corps is a goal that both Presidents George W. Bush and Barack Obama have embraced.

Volunteers for Prosperity will tap 75,000 skilled Americans for flexible term assignments to work on international challenges Congress and many Presidents have made priorities, such as HIV/AIDS, malaria, and clean water. Global Service Fellows will enable Members of Congress to nominate top talent from their districts and states, as they do for the military academies today, to serve for up to one year abroad. Together with the Peace Corps, these efforts will meet John Kennedy's goal of mobilizing 100,000 Americans to serve abroad each year.

The Service World plan focuses on multi-lateral partnerships and exchanges so Americans serve side-by-side with people from other countries, including in the United States. Under the plan, both skilled and non-skilled volunteers of all classes and ages will serve abroad for both long- and short-term assignments and veterans have specific opportunities to utilize their many skills in a civilian capacity. We believe an inclusive and mobile model of volunteering will contribute to the development of a new generation of global leaders, provide skills for U.S. citizens to compete in a global economy, increase international awareness, strengthen development, and improve the image of America abroad.

Volunteer service by people of all nations should become a common strategy in meeting pressing challenges in education, health, the environment, agriculture and more. By having national policies that engage more Americans in international service at every stage of life, we will be sharing our most valuable assets - the skills, talents and perspectives of our people - to make a significant difference in communities and nations throughout the world.

Editors’ Note: How do states manage their armed forces, domestic politics, and foreign affairs? Stephen Cohen, senior fellow with the India Project at Brookings, has studied this and a range of other issues in Southeast Asia since the 1960s. In a new book, titled “The South Asia Papers: A Critical Anthology of Writings,” Cohen reflects on more than a half-century of scholarship on India, describing the dramatic changes he has personally witnessed in the field of research. The following is an excerpt from the book’s preface.

[In the 1960s, questions about how states manage their armed forces] were not only unasked in the South Asian context by scholars; they were also frowned on by the Indian government. This made preparation both interesting and difficult. It was interesting because a burgeoning literature on civil–military relations in non-Western states could be applied to India. Most of it dealt with two themes: the “man on horseback,” or how the military came to power in a large number of new states, and how the military could assist in the developmental process. No one had asked these questions of India, although the first was relevant to Pakistan, then still governed by the Pakistani army in the form of Field Marshal Ayub Khan.

***

During my first and second trips [in the 1960s] my research was as a historian, albeit one interested in the army’s social, cultural, and policy dimensions. I discovered, by accident, that this was part of the movement toward the “new military history.” Over the years I have thus interacted with those historians who were interested in Indian military history, including several of my own students. 

While the standard of historians in India was high in places like the University of Calcutta, military history was a minor field, just as it was in the West. Military historians are often dismissed as the “drums and trumpets” crowd, interested in battles, regiments, and hardware, but not much else. My own self-tutoring in military history uncovered something quite different: a number of scholars, especially sociologists, had written on the social and cultural impact of armed forces, a literature largely ignored by the historians. While none of this group was interested in India, the connection between one of the world’s most complicated and subtle societies, the state’s use of force, and the emergence of a democratic India was self-evident. 

***

A new generation of scholars and experts, many of them Indians (some trained in the United States) and Indian Americans who have done research in India, have it right: this is a complex civilizational-state with expanding power, and its rise is dependent on its domestic stability, its policies toward neighbors (notably Pakistan), the rise of China, and the policies of the United States. 

The literature that predicts a conflict between the rising powers (India and China), and between them and America the “hegemon,” is misguided: the existence of nuclear weapons by all three states, plus Pakistan, ensures that barring insanity, any rivalries between rising and established states will be channeled into “ordinary” diplomatic posturing, ruthless economic competition, and the clash of soft power. In this competition, India has some liabilities and many advantages, and the structure of the emerging world suggests a closer relationship between the United States and India, without ruling out much closer ties between China and India. 

There remain some questions: Can the present Indian leadership show magnanimity in dealing with Pakistan, and does it have the foresight to look ahead to new challenges, notably environmental and energy issues that require new skills and new international arrangements? Importantly, some of the best work on answering these questions is being done in India itself, and the work of Kanti Bajpai, Amitabh Mattoo, Harsh Pant, C. Raja Mohan, Rajesh Basrur, and others reveals the maturity of Indian thinking on strategic issues. It has not come too soon, as the challenges that India will face are growing, and those of Pakistan are even more daunting.

Key messages and Policy Pointers

• Given the stalemate in U.N. climate negotiations, the best arena to strike a workable deal is among the members the Major Economies Forum on Energy and Climate (MEF).

• The 13 MEF members—including the EU-27 (but not double-counting the four EU countries that are also individual members of the MEF)—account for 81.3 percent of all global emissions.

• This proposal devises a fair compromise to break the impasse to develop a science-based approach for fairly sharing the carbon budget in order to have a 75 percent chance of avoiding dangerous climate change.

• To increase the likelihood of a future climate agreement, carbon accounting must shift from pro­duction-based inventories to consumption-based ones.

• The shares of a carbon budget to stay below 2 °C through 2050 are calculated by cumulative emis­sions since 1990, i.e. according to a short-horizon polluter pays principle, and national capability (income), and allocated to MEF members through emission rights. This proposed fair compromise addresses key concerns of major emitters.

• According to this accounting, no countries have negative carbon budgets, there is substantial time for greening major developing economies, and some developed countries need to institute very rapid reductions in emissions.

• To provide a ‘green ladder’ to developing countries and to ensure a fair global deal, it will be crucial to agree how to extend sufficient and predictable financial support and the rapid transfer of technology.

The most urgent and complicated ethical issue in addressing climate change is how human society will share the work of reducing greenhouse gases (GHG) emissions. Looking ahead to 2015 when a new international treaty on climate change should be agreed upon, we fear we are headed towards a train wreck.

Key developed countries have made it clear they will not accept any regime excluding emerging economies such as China and Brazil, and the U.S. and other ‘umbrella’ countries are calling for only voluntary, bottom-up com­mitments. Yet the major developing countries have made equity the sine qua non for any kind of agreement: they will not take on mandatory emission reduction targets with perceived implications for their economic growth and social development, unless the wealthier countries commit to deep emissions cuts and act first.

These entrenched positions between the different blocs have led to the current impasse, but as Nobel laureate economist and philosopher, Amaryta Sen pointed out, the perfect agreement that never happens is more unjust than an imperfect one that is obtainable.

What is a fair and feasible way to break the impasse, given that all efforts are faltering? The most difficult task is determining a country’s fair share of the required emissions reductions in a way that is politically feasible. After 20 years of negotiations and gridlock, it is clear that many conflicting principles of equity are brought to the table, so a solution will have to be based on some kind of ‘negotiated justice,’ or a ‘fair compromise,’ which will not be one preferred by just one group of countries.

A few basic requirements must be met. A feasible, fair and effective climate agreement must involve the largest emitters from both the developed and developing countries. Such an agreement must find a way to engage the latter without penalizing them or the former countries too much. In order to secure progress, above all it must be acceptable to the two world superpowers and top carbon emitters, China and the U.S.; with this leadership, in fact, other emitters will likely follow. This agreement could be forged in a ‘plurilateral’ setting where a limited number of countries come together first, and then be brought into the formal U.N. negotiations as the basis for a future deal, perhaps by 2015.

How can future negotiations on emissions reductions overcome such political inertia? We suggest that taking three manageable steps to a fair compromise will unlock progress.

First, negotiate a core agreement between the 13 members in the MEF (including the EU-27), which accounts for 81.3 percent of all global emissions. This makes the negotiations feasible, where deals can be struck that would be impossible in the vast U.N. forum.

Second, use consumption-based emissions accounting, which is much fairer than the cur­rent production/territorial-based accounting that all past agreements and negotiations have been based upon. These are relatively new numbers developed by the Norwegian research center CICERO, and have been vetted by the top scientific journals and increasingly utilized by policymakers.

Third, forge a fair compromise to allocate emissions rights. We propose a compromise based on a short-horizon ‘polluter pays principle’ and an indicator of national capability (income).

This third step in particular is a genuine compromise for both developed and developing countries, but it is re­quired to break the current gridlock. Each MEF member gives and takes something from this simple, workable framework and all gain a liveable planet in the future.

Throughout the paper we first explain why counting carbon emissions by consumption is far better and the im­plications of doing so, and we then introduce the MEF and why it is a promising arena for forging a bold compro­mise like the one so badly needed before 2015. We then calculate what the numbers actually mean for that group of countries and develop a proposal for a fair compromise that embodies a feasible but fair operationalization of the central equity principles of the U.N. climate treaty, i.e. action by countries according to their responsibility and capability. We conclude with a discussion of how a start in the MEF could lead to a new framework being brought into those broader negotiations.

Editor's Note: In an interview with La Repubblica's Rosalba Castelletti, Jonathan Laurence discussed the significance of the revelations that the United States has continued to spy on Germany, and what they mean for the future of the transatlantic relationship.

"È un momento delicato, ma non penso che la Germania abbia interesse ad esagerare le tensioni con gli Stati Uniti". A sostenerlo è Jonathan Laurence, professore di Scienze politiche al Boston College ed esperto di Relazioni transatlantiche presso il think tank Brookings Institution di Washington.

Professor Laurence, quest'episodio come inciderà sulle relazioni tra i due Paesi?

"La situazione è tesa. Berlino stavolta non ha espresso solo la consueta indignazione, ma ha compiuto un atto formale con l'espulsione del capo dei servizi segreti, perché è la terza volta che il popolo tedesco apprende di essere spiato dagli americani. La prima volta è successo con il Datagate, la seconda con l'intercettazione del cellulare della cancelliera e ora con due spie tedesche al soldo degli americani".

In cosa differisce quest'ultimo caso dai precedenti?

"Non si tratta di programmi d'alta tecnologia, ma di spionaggio più "vecchia maniera": documenti in cambio di soldi. Stavolta poi non c'è in ballo un problema di sicurezza internazionale. È un nuovo colpo per la reputazione Usa perché ancora una volta si dimostra indifferente alla sensibilità europea riguardo alla raccolta di dati".

E i tedeschi sono forse i più sensibili, visto che hanno sperimentato lo spionaggio della Gestapo e della Stasi...

"Di fatti. L'attuale cancelliera ha fatto il suo debutto in politica proprio dopo il crollo della Stasi. Ecco perché dobbiamo aspettarci che la Germania dichiari a gran voce la sua collera".

Cosa può fare l'amministrazione Usa per riparare?

"Qualcosa di più che cercare infruttuosi colloqui bilaterali o accordi di non spionaggio reciproco. La Germania non è ingenua, sa che i servizi americani hanno bisogno di operare soprattutto dopo il 2001, ma vuole che si lavori insieme. Non credo però che cerchi il conflitto. Berlino e Washington hanno bisogno l'una dell'altra sia sulle sanzioni contro la Russia in merito alla crisi Ucraina sia sull'accordo di libero scambio".

Renewable energy is an important source to tackle against climate change, as the latest IPCC report has pointed out. However, due to the existence of multiple market failures such as negative externalities of fossil fuels and knowledge spillovers of new technology, government subsidies are still needed to develop renewable energy, such as solar photovoltaic (PV) cells. In the United States, there have been various forms of subsidies for PV, varying from the federal level to the state level, and from the city level to the utility level. California, as the pioneer of solar PV development, has put forward the biggest state-level subsidy program for PV, the California Solar Initiative (CSI). The CSI has planned to spend around $2.2 Billion in 2007–2016 to install roughly 2 GW PV capacity, with the average subsidy level as high as $1.1/W. How to evaluate the cost-effectiveness and incentive pass-through of this program are the two major research questions we are pursing.

Our cost-effectiveness analysis is based on a constrained optimization model that we developed, where the objective is to install as much PV capacity as possible under a fixed budget constraint. Both the analytical and computational results suggest that due to a strong peer effect and the learning-by-doing effect, one can shift subsides from later periods to early periods so that the final PV installed capacity can be increased by 8.1% (or 32 MW). However, if the decision-maker has other policy objectives or constraints in mind, such as maintaining the policy certainty, then, the optimally calculated subsidy policy would look like the CSI.

As to the incentive pass-through question, we took a structural approach and in addition used the method of regression discontinuity (RD). While in general, the incentive pass-through rate depends on the curvature of the demand and supply curve and the level of market competition, our two estimations indicate that the incentive pass-through for the CSI program is almost complete. In other words, almost all of the incentive has been enjoyed by the customer, and the PV installers did not retain much. Based on the RD design, we observe that PV installers tend to consider the CSI incentive as exogenous to their pricing decision.

The relative good performance of the CSI in terms of both the cost-effectiveness and the incentive pass-through aspect are tightly related to its policy design and program management. International speaking, the biggest challenge for the design of any PV subsidy program is the quick running out of the budget, and in the end, it looks like customers are rushing for the subsidy. Such rushing behavior is a clear indication of higher-than-needed incentive levels. Due to the policy rigidity and rapid PV technological change, the PV subsidy policy may lag behind the PV cost decline; and as a result, rational customers could rush for any unnecessarily high subsidy.

Due to the high uncertainty and unpredictability of future PV costs, the CSI put forward a new design that links the incentive level change and the installed capacity goal fulfillment. Specifically, the CSI has designed nine steps to achieve its policy goal; at each step, there is a PV capacity goal that corresponds to an incentive level. Once the capacity goal is finished, the incentive level will decrease to the next lower level. Furthermore, to maintain the policy certainty, the CSI regulated that every step-wise change in the incentive level should not be higher than $0.45/W, nor smaller than $0.05/W, together with other three constraints.

A good subsidy policy not only requires flexible policy design to respond to fast-changing environment, but also demands an efficient program management system, digitalized if possible. For the CSI, the authority has contracted out a third-party to maintain a good database system for the program. Specifically, the database has documented in detail every PV system that customers requested. Key data fields include 22 important dates during the PV installation process, customers’ zip code, city, utility and county information, and various characteristics of the PV system such as price, system size, incentive, PV module and installer. All information is publicly available, which to some extent fills in the information gap held by customers and fosters the market competition among PV installers. For customers to receive the incentive, their PV systems have to pass the inspection of the local government, and also to be interconnected to the grid. On the supply side, the CSI has also certified and created a list of PV installers that every customer can choose from.

Although the CSI has ended in 2014 due to fast PV cost reduction starting from 2009, its experience has been transferred to other areas in the United States and in Europe. It is highly possible that other similar new technologies and products (e.g. the electric car and the battery) can adopt the CSI policy design, too. In summary, a good and successful policy may need to be simply, clear, credible, foreseeable, flexible, end-able, and incentive-compatible. The PV subsidy policy in China still has a long way to go when compared to the CSI.
