A Fiscal Stimulus and Jobless Recovery
We analyse the effects of a government spending expansion in a DSGE model with Mortensen-Pissarides labour market frictions, deep habits in private and public consumption, investment adjustment costs, a constant-elasticity-of-substitution (CES) production function, and adjustments in employment both at the intensive as well as the extensive margin. The combination of deep habits and CES technology is crucial. The presence of deep habits magnifies the responses of macroeconomic variables to a fiscal stimulus, while an elasticity of substitution between capital and labour in the range of available estimates allows the model to produce a scenario compatible with the observed jobless recovery.
Optimal Fiscal and Monetary Policy, Debt Crisis and Management
The initial government debt-to-GDP ratio and the government’s commitment play a pivotal role in determining the welfare-optimal speed of fiscal consolidation in the management of a debt crisis. Under commitment, for low or moderate initial government debt-to-GPD ratios, the optimal consolidation is very slow. A faster pace is optimal when the economy starts from a high level of public debt implying high sovereign risk premia, unless these are suppressed via a bailout by official creditors. Under discretion, the cost of not being able to commit is reflected into a quick consolidation of government debt. Simple monetary-fiscal rules with passive fiscal policy, designed for an environment with “normal shocks”, perform reasonably well in mimicking the Ramsey-optimal response to one-off government debt shocks. When the government can issue also long-term bonds–under commitment–the optimal debt consolidation pace is slower than in the case of short-term bonds only, and entails an increase in the ratio between long and short-term bonds.

Breaking the Barriers to Higher Economic Growth
The world's attention to the countries of the Middle East and North Africa (MENA) region has often been dominated by headline issues: conflict, sanctions, political turmoil, and rising oil prices. Little of this international attention has considered the broad range of development challenges facing this diverse group of countries. Breaking the Barriers reflects the collected thinking of the World Bank's Office of the Chief Economist for the MENA Region on the long-term development challenges facing the region and the reform priorities and strategies for effectively meeting these challenges. It.
PPP Strikes Back
We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time-series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When heterogeneity is properly taken into account, estimates of the real exchange rate half-life fall dramatically, to little more than one year, or significantly below Rogoff''s "consensus view" of three to five years. We show that corrected estimates are consistent with plausible nominal rigidities, thus, arguably, solving the PPP puzzle.
Dosso's Fate
Dosso Dossi has long been considered one of Renaissance Italy's most intriguing artists. Although a wealth of documents chronicles his life, he remains, in many ways, an enigma, and his art continues to be as elusive as it is compelling. In Dosso's Fate, leading scholars from a wide range of disciplines examine the social, intellectual, and historical contexts of his art, focusing on the development of new genres of painting, questions of style and chronology, the influence of courtly culture, and the work of his collaborators, as well as his visual and literary sources and his painting technique. The result is an important and original contribution not only to literature on Dosso Dossi but also to the study of cultural history in early modern Italy.
Advanced Macroeconomics
This is a newly revised second edition of a key macroeconomic textbook. After explaining the historical development of the subject, they show how rational expectations are handled in macro models. The importance of structural micro-founded models is explained, with key examples of such structural models examined in detail and with extensions to the open economy; policy implications are highlighted throughout. Methods for testing these models against macro data behaviour are explained, detailing the latest evidence on these models' success.
Inequality and the Labor Market
Exploring a new agenda to improve outcomes for American workers As the United States continues to struggle with the impact of the devastating COVID-19 recession, policymakers have an opportunity to redress the competition problems in our labor markets. Making the right policy choices, however, requires a deep understanding of long-term, multidimensional problems. That will be solved only by looking to the failures and unrealized opportunities in anti-trust and labor law. For decades, competition in the U.S. labor market has declined, with the result that American workers have experienced slow wage growth and diminishing job quality. While sluggish productivity growth, rising globalization, a...
