Risk sharing in an economy is achieved by the contribution of different sectors. Government, households, and corporations sectors contribute to risk sharing, but the extent of their role on risk-sharing has not been so far quantified. We investigate risk sharing channels across economic sectors to quantify to what extent they contribute offsetting idiosyncratic shocks. We examine the two most relevant channels of smoothing among OECD and EU countries: the international investment income and the savings channels. We find that the households' share in net foreign asset income has a significant role in risk sharing. This surprising result is strictly related to the accumulation of households' foreign asset holdings. On the contrary, governments' cross-border holdings produce a dis-smoothing effect and this might be imputable to the holding of EU countries' assets. This outcome is reversed for the new EU countries in the post Global Financial Crisis (GFC) period. With regard to the savings channel, we find that governments significantly contribute to risk sharing, and more significantly after the inception of the GFC. Moreover, the dividend smoothing theory reconciles with the risk-sharing findings since corporations (in particular non financial) significantly smooth shocks through their savings, however their contribution to risk sharing is weak in the post-GFC era.

This book examines the application of risk-sharing finance as a national economic policy in history and how it stimulated economic recovery during a short period in Germany between 1933 and 1935. Economic history indicates that risk-sharing instruments have promoted socio-economic development in many parts of the world while risk-shifting methods have imposed huge socio-economic costs on many nations, leading to debt slavery on individual members. This book highlights lessons to be learned from history and argues that risk-sharing is a powerful tool for generating rapid economic recovery and resumption of growth.

"This white paper focusses on the policy interventions made to help people manage risk, uncertainty and the losses from events whose impacts are channeled primarily through the labor market. The objectives of the white paper are: to scrutinize the relevance and effects of prevailing risk-sharing policies in low- and middle-income countries; take account of how global drivers of disruption shape and diversify how people work; in light of this diversity, propose alternative risk-sharing policies, or ways to augment and improve current policies to be more relevant and responsive to peoples' needs; and map a reasonable transition path from the current to an alternative policy approach that substantially extends protection to a greater portion of working people and their families. This white paper is a contribution to the broader, global discussion of the changing nature of work and how policy can shape its implications for the wellbeing of people. We use the term risk-sharing policies broadly in reference to the set of institutions, regulations and interventions that societies put in place to help households manage shocks to their livelihoods. These policies include formal rules and structures that regulate market interactions (worker protections and other labor market institutions) that help people pool risks (social assistance and social insurance), to save and insure affordably and effectively (mandatory and incentivized individual savings and other financial instruments) and to recover from losses in the wake of livelihood shocks ('active' reemployment measures). Effective risk-sharing policies are foundational to building equity, resilience and opportunity, the strategic objectives of the World Bank's Social Protection and Jobs Global Practice. Given failures of factor markets and the market for risk in particular the rationale for policy intervention to augment the options that people have to manage shocks to their livelihoods is well-understood and accepted. By helping to prevent vulnerable people from falling into poverty --and people in the poorest households from falling deeper into poverty-- effective risk-sharing interventions dramatically reduce poverty. Households and communities with access to effective risk-sharing instruments can better maintain and continue to invest in these vital assets, first and foremost, their human capital, and in doing so can reduce the likelihood that poverty and vulnerability will be transmitted from one generation to the next. Risk-sharing policies foster enterprise and development by ensuring that people can take appropriate risks required to grasp opportunities and secure their stake in a growing economy."--

"Socially inclusive growth is the talk of the town in developing countries. But to go from talk to walk these countries face a critical task: reconstructing their welfare states given the failures of the standard Bismarckian model and the challenges posed by rapid technological change. This book—known to many as the White Paper—is indispensable for tackling this task. It develops a clear conceptual framework to help policy makers understand this complex issue, set clear objectives, evaluate trade-offs, and chart a coherent path of reform. A much-needed and very welcome contribution." --Santiago Levy, Senior Fellow—Global Economy and Development, Brookings Economic and Social Policy in Latin America Initiative, Brookings Institution "Most countries have failed to support people adequately as the combination of globalization and technology changes the structure of their economies and their jobs. This has fostered a backlash in which economic insecurity is widespread and support for populist policies is on the rise. We can do much better than this by sharing risks and providing a guaranteed minimum to everyone. This important book lays out a set of policies that strikes a new balance between economic flexibility and individual security that is relevant to both advanced and developing countries." --Minouche Shafik, Director, London School of Economics and Political Science "Economic insecurity confronts working people around the world today. To overcome this insecurity through suitable risk-sharing interventions is a policy challenge of the first order. This exceptionally thoughtful and clearly written book charts a course for replacing employment-based risk-sharing policies with social insurance†“based ones, financed by general revenues with the broadest possible base. The resultant Flexicurity model promises 'a more robust and resilient policy response to a diverse and fluid world of work.' " --Gary Fields, Professor of International and Comparative Labor and Professor of Economics, Cornell University "Protecting All presents thoughtful, thorough, and bold proposals to achieve universal social protection in a modern welfare state. This lucid document identifies implementable policies for poverty prevention, coping with livelihood shocks, and managing labor market risks that range from state-guaranteed publicly funded income floors to mandated consumption-smoothing mechanisms funded by individual contributions to privately financed incentivized and purely voluntary consumption-smoothing schemes. Clearly written, rich with ideas, and relevant for countries at all income levels, Protecting All is bound to become an essential reference for policy makers and policy analysts focused on (re)designing social protection systems that achieve key social goals in ways consistent with fast-changing labor markets, fiscal sustainability, and economic efficiency and growth." --Nora Lustig, Professor of Latin American Economics and Director of the Commitment to Equity Institute, Tulane University

Cochrane (1991 , Journal of Political Economy 99, 957--976) and Mace (1991 , Journal of Political Economy 99, 928--956) test if risk sharing across households is complete in the sense that household consumption moves one-for-one with aggregate consumption. In their studies the source of income risk is idiosyncratic, and agents can share risk across the entire economy. Using a sample of households from the Panel Study on Income Dynamics (PSID), we explore whether households share the risk associated with their industries and regions across households in other regions and industries. We find that a large fraction of risk faced by households is not shared across regions and industries. Keyword(s): Risk sharing; Quantity anomaly.

Monetary aggregates continue to play an important role in the ECB's policy strategy. This paper revisits the case for money, surveying the ongoing theoretical and empirical debate. The key conclusion is that an exclusive focus on non-monetary factors alone may leave the ECB with an incomplete picture of the economy. However, treating monetary factors as a separate matter is a second-best solution. Instead, a general-equilibrium inspired analytical framework that merges the economic and monetary "pillars" of the ECB's policy strategy appears the most promising way forward. The role played by monetary aggregates in such unified framework may be rather limited. However, an integrated framework would facilitate the presentation of policy decisions by providing a clearer narrative of the relative role of money in the interaction with other economic and financial sector variables, including asset prices, and their impact on consumer prices.
