Intelligence does not arise only in individual brains; it also arises in groups of individuals. This is collective intelligence: groups of individuals acting collectively in ways that seem intelligent. In recent years, a new kind of collective intelligence has emerged: interconnected groups of people and computers, collectively doing intelligent things. Today these groups are engaged in tasks that range from writing software to predicting the results of presidential elections.

Solutions to odd-numbered problem set questions in Modern Macroeconomics.

The modern study and analysis of macroeconomics begins by considering how microeconomic units—consumers and firms—make decisions, and then investigates how these choices interact to yield economy-wide outcomes. This innovative textbook takes this “modern” approach, teaching macroeconomics through its microeconomic foundations. It does so by adopting the representative agent paradigm. By modeling the representative consumer and the representative firm, students will learn to describe macroeconomic outcomes and consider the effects of macroeconomic policies.

The Art of Policymaking in India

In December 2009, the economist Kaushik Basu left the rarefied world of academic research for the nuts and bolts of policymaking. Appointed by the then Prime Minister of India, Manmohan Singh, to be chief economic adviser (CEA) to the Government of India, Basu—a theorist, with special interest in development economics, and a professor of economics at Cornell University—discovered the complexity of applying economic models to the real world. Effective policymaking, Basu learned, integrates technical knowledge with political awareness.

A Nontechnical View

Macroeconomists have been caricatured either as credulous savants in love with the beauty of their mathematical models or as free-market fundamentalists who admit no doubt as to the market’s wisdom. In this book, Kartik Athreya draws a truer picture, offering a nontechnical description of prominent ideas and models in macroeconomics, and arguing for their value as interpretive tools as well as their policy relevance.

Leading Economists Predict the Future

This pithy and engaging volume shows that economists may be better equipped to predict the future than science fiction writers. Economists’ ideas, based on both theory and practice, reflect their knowledge of the laws of human interactions as well as years of experimentation and reflection. Although perhaps not as screenplay-ready as a work of fiction, these economists’ predictions are ready for their close-ups. In this book, ten prominent economists—including Nobel laureates and several likely laureates—offer their ideas about the world of the twenty-second century.

Economists argue that such market-based policy instruments as environmental taxes and emission trading systems are the best way to target the negative effects of pollution. Yet there is no agreement about whether the use of these instruments is sufficient, whether they are deployed efficiently, and which factors influence their effectiveness. Nor is it clear if such policies have had any significant effect on the urgent matter of climate change mitigation.

Evaluation and Prospects

Emissions trading schemes figure prominently among policy instruments used to tackle the problem of climate change, and the European Union Emissions Trading Scheme (EU ETS), begun in 2005, is the largest cap-and-trade market so far established. In the EU ETS, firms regulated by the scheme are provided with emissions allowances (each a one-time right to emit one ton of greenhouse gases) and can sell their unused allowances to firms that have higher rates of emissions.

The recent financial crisis has shattered all standard approaches to banking regulation. Regulators now recognize that banking regulation cannot be simply based on individual financial institutions’ risks. Instead, systemic risk and macroprudential regulation have come to the forefront of the new regulatory paradigm. Yet our knowledge of these two core aspects of regulation is still limited and fragmented. This book offers a framework for understanding the reasons for the regulatory shift from a microprudential to a macroprudential approach to financial regulation.

Pivotal Events in Valuing Work and Delivering Results

In 2009, the Ford Motor Company was the only one of the Big Three automakers not to take the federal bailout package. How did Ford remain standing when its competitors were brought to their knees? It was a gutsy decision, but it didn’t happen in isolation. The United Auto Workers joined with Ford to make this possible—not only in 2009, but in a series of more than fifty pivotal events during three decades that add up to a transformation that simultaneously values work and delivers results.
