Setting macroeconomic policy is especially difficult in fragile states. Political legitimacy concerns are heightened, raising issues such as who the policymakers are, what incentives they face, and how the process of policymaking is likely to work under limited legitimacy and high uncertainty both about the macroeconomic environment as well as policy effectiveness. In addition, fragility expands the range of policy objectives in ways that may constrain the attainment of standard macroeconomic objectives. Specifically, in the context of fragility policymakers also need to focus on measures to mitigate fragility itself - i.e., they need to address issues such as regional and ethnic economic disparities, youth unemployment, and food price inflation. Socio-political developments around the world have thus pushed policymakers to broaden their toolkit to improve the effectiveness of macroeconomic management in the face of these constraints. The chapters in Macroeconomic Policy in Fragile States address these issues, both by giving an analytical context from which policymakers can build to answer the questions they face in fragile situations as well as by providing lessons drawn from empirical analyses and case studies. The first section of the volume discusses the interactions between political economy considerations and macroeconomic policymaking. The second section covers the private sector environment in fragile states. The third section focuses on macroeconomic policy, especially fiscal policy, monetary policy, exchange rate policy, external flows, and aid effectiveness. The last section explains the role of the IMF in fragile states and concludes by presenting case studies from the Middle East and from Sub-Saharan Africa. The contributors to the volume are economists and political scientists from academia as well as policymakers from international organizations and from countries affected by fragility.

The global financial crisis triggered severe shocks for developing countries, whose embrace of greater commercial and financial openness has increased their exposure to external shocks, both real and financial. This new edition of Development Macroeconomics has been fully revised to address the more open and less stable environment in which developing countries operate today. Describing the latest advances in this rapidly changing field, the book features expanded coverage of public debt and the management of capital inflows as well as new material on fiscal discipline, monetary policy regimes, currency, banking and sovereign debt crises, currency unions, and the choice of an exchange-rate regime. A new chapter on dynamic stochastic general equilibrium (DSGE) models with financial frictions has been added to reflect how the financial crisis has reshaped our thinking on the role of such frictions in generating and propagating real and financial shocks. The book also discusses the role of macroprudential regulation, both independently and through its interactions with monetary policy, in preserving financial and macroeconomic stability. Now in its fourth edition, Development Macroeconomics remains the definitive textbook on the macroeconomics of developing countries. * The most authoritative book on the subject--now fully revised and expanded* Features new material on fiscal discipline, monetary policy regimes, currency, banking and sovereign debt crises, and much more* Comes with online supplements on informal financial markets, stabilization programs, the solution of DSGE models with financial frictions, and exchange rate crises

The macroeconomic experience of emerging and developing economies has tended to be quite different from that of industrial countries. Compared to industrial countries, emerging and developing economies have tended to be much more unstable, with more severe boom/bust cycles, episodes of high inflation, and a variety of financial crises. This textbook describes how the standard macroeconomic models that are used in industrial countries can be modified to help understand this experience, and how institutional and policy reforms in emerging and developing economies may affect their future macroeconomic performance. This second edition differs from the first in offering - extensive new material on themes such as fiscal institutions, inflation targeting, emergent market crises, and the Great Recession - numerous application boxes - end-of-chapter questions - references for each chapter - more diagrams, less taxonomy, and a more reader-friendly narrative - enhanced integration of all parts of the work.

There is little doubt that the vertebrate brain is the most complex structure we know. As with any complex structure, there is the immediate question about its origins. How could such a complex design develop from the simplest multicellular animals? This problem has pervaded the study of evolutionary biology since its beginnings. Although Darwin (1859, 1871) proposed an impecable mechanism (natural selection) for the gradual transformation of species including human origins, even he sometimes expressed certain doubts about the origin of highly complex structures. This issue has been highly debated both within science and outside it.

The authors follow an approach that has been termed "developmental evolutionary genetics," which seeks to establish a correspondence between embryological processes and the phylogenetic history of an organism. Modern understanding of these hypotheses acknowledges that in fact, early embryos are readily distinguishable among them, and that human embryos are human embryos during all development; they do not pass from a jellyfish stage to a fish stage and so on (Garstang 1922; Gould 1977; Richardson et al. 1997). However, it is also recognized that embryos pass through successive stages in which they acquire the characters proper to each of the nested phylogenetic categories to which they belong. Thus, there is a general concordance between embryonic stages and the phylogenetic history.
