The past thirty years have witnessed a transformation of government economic intervention in broad segments of industry throughout the world. Many industries historically subject to economic price and entry controls have been largely deregulated, including natural gas, trucking, airlines, and commercial banking. However, recent concerns about market power in restructured electricity markets, airline industry instability amid chronic financial stress, and the challenges created by the repeal of the Glass-Steagall Act, which allowed commercial banks to participate in investment banking, have led to calls for renewed market intervention.Economic Regulation and Its Reform collects research by a group of distinguished scholars who explore these and other issues surrounding government economic intervention. Determining the consequences of such intervention requires a careful assessment of the costs and benefits of imperfect regulation. Moreover, government interventions may take a variety of forms, from relatively nonintrusive performance-based regulations to more aggressive antitrust and competition policies and barriers to entry. This volume introduces the key issues surrounding economic regulation, provides an assessment of the economic effects of regulatory reforms over the past three decades, and examines how these insights bear on some of today's most significant concerns in regulatory policy.

The oldest members of the Baby-Boomer generation are now crossing the threshold of eligibility for Social Security and Medicare with extensive and significant implications for these programs' overall spending and fiscal sustainability. Yet the aging of the Baby Boomers is just one part of the rapidly changing landscape of aging in the United States and around the world.The latest volume in the NBER's Economics of Aging series, Discoveries in the Economics of Aging assembles incisive analyses of the most recent research in this expanding field of study. A substantive focus of the volume is the well-documented relationship between health and financial well-being, especially as people age. The contributors explore this issue from a variety of perspectives within the context of the changing demographic landscape. The first part of the volume explores recent trends in health measurement, including the use of alternative measurement indices. Later contributions explore, among other topics, alternate determinants of health, including retirement, marital status, and cohabitation with family, and the potential for innovations, interventions, and public policy to improve health and financial well-being.

Understanding the challenges of corporate governance is central to our comprehension of the economic dynamics driving corporations today. Among the most important institutions in capitalism today, corporations and joint-stock companies had their origins in Europe during the seventeenth and eighteenth centuries. And as they became more prevalent, the issue of internal governance became more pressing. At stake-and very much contested-was the allocation of rights and obligations among shareholders, directors, and managers.This comprehensive account of the development of corporate governance in Britain and Ireland during its earliest stages highlights the role of political factors in shaping the evolution of corporate governance as well as the important debates that arose about the division of authority and responsibility. Political and economic institutions confronted similar issues, including the need for transparency and accountability in decision making and the roles of electors and the elected, and this book emphasizes how political institutions-from election procedures to assemblies to annual reporting-therefore provided apt models upon which companies drew readily. Filling a gap in the literature on early corporate economy, this book provides insight into the origins of many ongoing modern debates.

On museum visits, we pass by beautiful, well-preserved vases from ancient Greece-but how often do we understand what the images on them depictIn Image and Myth, Luca Giuliani tells the stories behind the pictures, exploring how artists of antiquity had to determine which motifs or historical and mythic events to use to tell an underlying story while also keeping in mind the tastes and expectations of paying clients.?Covering the range of Greek style and its growth between the early Archaic and Hellenistic periods, Giuliani describes the intellectual, social, and artistic contexts in which the images were created. He reveals that developments in Greek vase painting were driven as much by the times as they were by tradition-the better-known the story, the less leeway the artists had in interpreting it. As literary culture transformed from an oral tradition, in which stories were always in flux, to the stability of written texts, the images produced by artists eventually became nothing more than illustrations of canonical works. At once a work of cultural and art history, Image and Myth builds a new way of understanding the visual culture of ancient Greece.

For Dante and Petrarch, posthumous love was a powerful conviction. Like many of their contemporaries, both poets envisioned their encounters with their beloved in heaven-Dante with Beatrice, Petrarch with Laura. But as Ramie Targoff reveals in this elegant study, English love poetry of the Renaissance brought a startling reversal of this tradition: human love became definitively mortal. Exploring the boundaries that Renaissance English poets drew between earthly and heavenly existence, Targoff seeks to understand this shift and its consequences for English poetry.?Targoff shows that medieval notions of the somewhat flexible boundaries between love in this world and in the next were hardened by Protestant reformers, who envisioned a total break between the two. Tracing the narrative of this rupture, she focuses on central episodes in poetic history in which poets developed rich and compelling compensations for the lack of posthumous love-from Thomas Wyatt's translations of Petrarch's love sonnets and the Elizabethan sonnet series of Shakespeare and Spencer to the?carpe diem?poems of the seventeenth century. Targoff's centerpiece is?Romeo and Juliet, where she considers how Shakespeare's reworking of the Italian story stripped away any expectation that the doomed teenagers would reunite in heaven. Casting new light on these familiar works of poetry and drama, this book ultimately demonstrates that the negation of posthumous love brought forth a new mode of poetics that derived its emotional and aesthetic power from its insistence upon love's mortal limits.

Work is changing. Speed and flexibility are more in demand than ever before thanks to an accelerating knowledge economy and sophisticated communication networks. These changes have forced a mass rethinking of the way we coordinate, collaborate, and communicate. Instead of projects coming to established teams, teams are increasingly converging around projects. These "e;all-edge adhocracies"e; are highly collaborative and mostly temporary, their edge coming from the ability to form links both inside and outside an organization. These nimble groups come together around a specific task, recruiting personnel, assigning roles, and establishing objectives. When the work is done they disband their members and take their skills to the next project.Spinuzzi offers for the first time a comprehensive framework for understanding how these new groups function and thrive. His rigorous analysis tackles both the pros and cons of this evolving workflow and is based in case studies of real all-edge adhocracies at work. His provocative results will challenge our long-held assumptions about how we should be doing work.
