The mobility of students in developed countries has dramatically increased over the last fifty years. Students do not necessarily remain in their countries of origin for higher education and work; they might be born in one country, attend university in a second, and find employment in a third.
The global financial crisis has prompted economists to rethink fundamental questions on how governments should intervene in the financial sector. Many countries have already begun to reform the taxation and regulation of the financial sector—in the United States, for example, the Dodd–Frank Act became law in 2010; in Europe, different countries have introduced additional taxes on the sector and made substantial progress toward a banking union for the eurozone. Only recently, however, has a new field in economics emerged to study the interplay between public finance and banking.
Portfolio management is a tough business. Each day, managers face the challenges of an ever-changing and unforgiving market, where strategies and processes that worked yesterday may not work today, or tomorrow. The usual advice for improving portfolio performance—refining your strategy, staying within your style, doing better research, trading more efficiently—is important, but doesn’t seem to affect outcomes sufficiently.
Auctions are highly structured market transactions primarily used in thin markets (markets with few participants and infrequent transactions). In auctions, unlike most other markets, offers and counteroffers are typically made within a structure defined by a set of rigid and comprehensive rules. Because auctions are essentially complex negotiations that occur within a fully defined and rigid set of rules, they can be analyzed by game theoretic models more accurately and completely than can most other types of market transactions.
The Dodd–Frank Wall Street Reform and Consumer Protection Act, passed by Congress in 2010 largely in response to the financial crisis, created the Financial Stability Oversight Council and the Consumer Financial Protection Bureau; among other provisions, it limits proprietary trading by banks, changes the way swaps are traded, and curtails the use of credit ratings. The effects of Dodd–Frank remain a matter for speculation; more than half of the regulatory rulemaking called for in the bill has yet to be completed.
This manual includes solutions to the odd-numbered exercises in Economic Dynamics in Discrete Time. Some exercises are purely analytical, while others require numerical methods. Computer codes are provided for most problems. Many exercises ask the reader to apply the methods learned in a chapter to solve related problems, but some exercises ask the reader to complete missing steps in the proof of a theorem or in the solution of an example in the book.
This book offers a unified, comprehensive, and up-to-date treatment of analytical and numerical tools for solving dynamic economic problems. The focus is on introducing recursive methods—an important part of every economist’s set of tools—and readers will learn to apply recursive methods to a variety of dynamic economic problems. The book is notable for its combination of theoretical foundations and numerical methods. Each topic is first described in theoretical terms, with explicit definitions and rigorous proofs; numerical methods and computer codes to implement these methods follow.
As the global economic crisis continues to cause damage, some policy makers have called for a more Keynesian approach to current economic problems. In this book, the economists Peter Temin and David Vines provide an accessible introduction to Keynesian ideas that connects Keynes’s insights to today’s global economy and offers readers a way to understand current policy debates.
Spreadsheets are used daily by millions of people for tasks that range from organizing a list of addresses to carrying out complex economic simulations. Spreadsheet programs are easy to learn and convenient to use because they have a clear visual model and a simple efficient underlying computational model. Yet although the basic spreadsheet model could be extended, improved, or otherwise experimented with in many ways, there is no coherently designed, reasonably efficient open source spreadsheet implementation that is a suitable platform for such experiments.
In 2011, the International Monetary Fund invited prominent economists and economic policymakers to consider the brave new world of the post-crisis global economy. The result is a book that captures the state of macroeconomic thinking at a transformational moment.
