Book Description
This paper performs a welfare analysis of economies with private information when public information is endogenously generated and agents can condition on noisy public statistics in the rational expectations tradition. We find that equilibrium is not (restricted) efficient even when feasible allocations share similar properties to the market context (e.g., linear in information). The reason is that the market in general does not internalize the informational externality when public statistics (e.g., prices) convey information. Under strategic substitutability, equilibrium prices will tend to convey too little information when the “informational” role of prices prevails over its index of “scarcity” role and too much information in the opposite case. Under strategic complementarity, prices always convey too little information. These results extend to the internal efficiency benchmark (accounting only for the collective welfare of the active players). However, received results -- on the relative weights placed by agents on private and public information, when the latter is exogenous -- may be overturned.

Book Description
Handbook of Macroeconomics Volumes 2A and 2B surveys major advances in macroeconomic scholarship since the publication of Volume 1 (1999), carefully distinguishing between empirical, theoretical, methodological, and policy issues, including fiscal, monetary, and regulatory policies to deal with crises, unemployment, and economic growth. As this volume shows, macroeconomics has undergone a profound change since the publication of the last volume, due in no small part to the questions thrust into the spotlight by the worldwide financial crisis of 2008. With contributions from the world’s leading macroeconomists, its reevaluation of macroeconomic scholarship and assessment of its future constitute an investment worth making. Serves a double role as a textbook for macroeconomics courses and as a gateway for students to the latest research Acts as a one-of-a-kind resource as no major collections of macroeconomic essays have been published in the last decade Builds upon Volume 1 by using its section headings to illustrate just how far macroeconomic thought has evolved

Book Description
The ramifications of the Global Financial Crisis, which erupted in 2007, continue to surprise not only the general public but also finance professionals, economists, and journalists. Faced with this challenge, Preparing for the Next Financial Crisis goes back to basics. The authors ask: what do theory and empirical observations tell us about the causes and the consequences of financial crisis and instability? In what has become an increasingly complex financial world, what lessons can we learn from economic policies, which have been implemented, and research, which has developed extremely rapidly in recent years, so as not to repeat past mistakes? In this comprehensive review of the literature, which is both complete and balanced, the authors highlight the points of consensus among economists and policymakers. They assess the capacity of economic policies and institutions in limiting the cost of financial instability. In conclusion, they ask if the financial system has become safer, in the light especially of the Covid-19 Global Crisis. Ten years after the GFC crisis, this is a timely review of the reform agenda, the progress made, and the areas where further changes need to be made to address new risks and challenges.

Book Description
The ways financial analysts, traders, and other specialists use information and learn from each other are of fundamental importance to understanding how markets work and prices are set. This graduate-level textbook analyzes how markets aggregate information and examines the impacts of specific market arrangements--or microstructure--on the aggregation process and overall performance of financial markets. Xavier Vives bridges the gap between the two primary views of markets--informational efficiency and herding--and uses a coherent game-theoretic framework to bring together the latest results from the rational expectations and herding literatures. Vives emphasizes the consequences of market interaction and social learning for informational and economic efficiency. He looks closely at information aggregation mechanisms, progressing from simple to complex environments: from static to dynamic models; from competitive to strategic agents; and from simple market strategies such as noncontingent orders or quantities to complex ones like price contingent orders or demand schedules. Vives finds that contending theories like informational efficiency and herding build on the same principles of Bayesian decision making and that "irrational" agents are not needed to explain herding behavior, booms, and crashes. As this book shows, the microstructure of a market is the crucial factor in the informational efficiency of prices. Provides the most complete analysis of the ways markets aggregate information Bridges the gap between the rational expectations and herding literatures Includes exercises with solutions Serves both as a graduate textbook and a resource for researchers, including financial analysts

Book Description
Gossip and reputation are core processes in societies and have substantial consequences for individuals, groups, communities, organizations, and markets.. Academic studies have found that gossip and reputation have the power to enforce social norms, facilitate cooperation, and act as a means of social control. The key mechanism for the creation, maintenance, and destruction of reputations in everyday life is gossip - evaluative talk about absent third parties. Reputation and gossip are inseparably intertwined, but up until now have been mostly studied in isolation. The Oxford Handbook of Gossip and Reputation fills this intellectual gap, providing an integrated understanding of the foundations of gossip and reputation, as well as outlining a potential framework for future research. Volume editors Francesca Giardini and Rafael Wittek bring together a diverse group of researchers to analyze gossip and reputation from different disciplines, social domains, and levels of analysis. Being the first integrated and comprehensive collection of studies on both phenomena, each of the 25 chapters explores the current research on the antecedents, processes, and outcomes of the gossip-reputation link in contexts as diverse as online markets, non-industrial societies, organizations, social networks, or schools. International in scope, the volume is organized into seven sections devoted to the exploration of a different facet of gossip and reputation. Contributions from eminent experts on gossip and reputation not only help us better understand the complex interplay between two delicate social mechanisms, but also sketch the contours of a long term research agenda by pointing to new problems and newly emerging cross-disciplinary solutions.

Book Description
A leading economist develops a supply-side approach to fighting climate change that encourages resource owners to leave more of their fossil carbon underground. The Earth is getting warmer. Yet, as Hans-Werner Sinn points out in this provocative book, the dominant policy approach—which aims to curb consumption of fossil energy—has been ineffective. Despite policy makers' efforts to promote alternative energy, impose emission controls on cars, and enforce tough energy-efficiency standards for buildings, the relentlessly rising curve of CO2 output does not show the slightest downward turn. Some proposed solutions are downright harmful: cultivating crops to make biofuels not only contributes to global warming but also uses resources that should be devoted to feeding the world's hungry. In The Green Paradox, Sinn proposes a new, more pragmatic approach based not on regulating the demand for fossil fuels but on controlling the supply. The owners of carbon resources, Sinn explains, are pre-empting future regulation by accelerating the production of fossil energy while they can. This is the “Green Paradox”: expected future reduction in carbon consumption has the effect of accelerating climate change. Sinn suggests a supply-side solution: inducing the owners of carbon resources to leave more of their wealth underground. He proposes the swift introduction of a “Super-Kyoto” system—gathering all consumer countries into a cartel by means of a worldwide, coordinated cap-and-trade system supported by the levying of source taxes on capital income—to spoil the resource owners' appetite for financial assets. Only if we can shift our focus from local demand to worldwide supply policies for reducing carbon emissions, Sinn argues, will we have a chance of staving off climate disaster.
