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.
