Identifying broad-scale evolutionary processes that maintain phenotypic polymorphisms has been a major goal of modern evolutionary biology. There are numerous mechanisms, such as negative frequency-dependent selection, that may maintain polymorphisms, although it is unknown which mechanisms are prominent in nature. Traits used for individual recognition are strikingly variable and have evolved independently in numerous lineages, providing an excellent model to investigate which factors maintain ecologically relevant phenotypic polymorphisms. Theoretical models suggest that individuals may benefit by advertising their identities with distinctive, recognizable phenotypes. Here, we test the benefits of advertising one's identity with a distinctive phenotype. We manipulated the appearance of Polistes fuscatus paper wasp groups so that three individuals had the same appearance and one individual had a unique, easily recognizable appearance. We found that individuals with distinctive appearances received less aggression than individuals with nondistinctive appearances. Therefore, individuals benefit by advertising their identity with a unique phenotype. Our results provide a potential mechanism through which negative frequency-dependent selection may maintain the polymorphic identity signals in P. fuscatus. Given that recognition is important for many social interactions, selection for distinctive identity signals may be an underappreciated and widespread mechanism underlying the evolution of phenotypic polymorphisms in social taxa.

This paper analyzes various reform options for Japan's public pension in light of large fiscal consolidation needs of the country. The most attractive option is to increase the pension eligibility age in line with high and rising life expectancy. This would have a positive effect on long-run economic growth and would be relatively fair in sharing the burden of fiscal adjustment between younger and older generations. Other attractive options include better targeting by \"clawing back\" a small portion of pension benefits from wealthy retirees, reducing preferential tax treatment of pension benefit incomes, and collecting contributions from dependent spouses of employees, who are currently eligible for pension benefits even though they make no contributions. These options, if implemented concurrently, could reduce the government annual subsidy and the government deficit by up to 1¼ percent of GDP by 2020.

China is at a critical juncture in its economic transition. A comprehensive reform of its pension and social security systems is an essential element of a strategy aimed toward achieving a harmonious society and sustainable development. Among policy makers, a widely held view is that the approach to pension provision and reform efforts piloted over the last 10-15 years is insufficient to enable China's economy and population to realize its development objectives in the years ahead. This volume suggests a national pension system that no longer distinguishes along urban and rural locational or hukou lines yet takes account of the diverse nature of employment relations and capacity of individuals to make contributions. This volume is organized as follows: the main text outlines this vision, focusing on summarizing the key features of a proposed long-term pension system. It first examines key trends motivating the need for reform then outlines the proposed three-pillar design and the rationale behind the design choices. It then moves on to examine financing options. The text continues by discussing institutional reform issues, and the final section concludes. The six appendixes provide additional analytical detail supporting the findings in the main text. The pension system design can play an important role in supporting or constraining such economic and demographic transitions: 1) fragmentation and lack of portability of rights hinder labor market efficiency and contribute to coverage gaps; 2) multiple schemes for salaried workers, civil servants, and, in some areas, migrants similarly impact labor markets; 3) legacy costs that are largely financed through current pension contributions weaken incentives for compliance and accurate wage reporting; 4) very limited risk pooling and interurban resource transfers limit the insurance function of the urban pension system and create spatial disparities in old-age income protection; 5) low retirement ages affect incentives and benefits and undermine fiscal sustainability; and 6) relatively low returns on individual accounts result in replacement rates significantly less than anticipated while at the macro level, are likely to inhibit wider efforts to stimulate higher domestic consumption.

The global textile and apparel sector is critically important as an early phase in industrialization for many developing countries and as a provider of employment opportunities to thousands of low-income workers, many of them women. The goal of this book is to explore how the lifting of the Multi-fibre Arrangement/ Agreement on Textiles and Clothing (MFA/ATC) quotas has affected nine countries Bangladesh, Cambodia, Honduras, India, Mexico, Morocco, Pakistan, Sri Lanka, and Vietnam with the broader aim of better understanding the links between globalization and poverty in the developing world. Analyzing how employment, wage premiums, and the structure of the apparel industry have changed after the MFA/ATC can generate important lessons for policy makers for economic development and poverty reduction. This book uses in-depth country case studies as the broad methodological approach. In-depth country studies are important because countries are idiosyncratic: differences in regulatory context, history, location, trade relationships, and policies shape both the apparel sector and how the apparel sector changed after the end of the MFA. In-depth country studies place broader empirical work in context and strengthen the conclusions. The countries in this book were chosen because they represent the diversity of global apparel production, including differences across regions, income levels, trade relationships, and policies. The countries occupy different places in the global value chain that now characterizes apparel production. Not surprisingly, the countries studied in this book represent the diversity of post-MFA experiences. This book highlights four key findings: The first is that employment and export patterns after the MFA/ATC did not necessarily match predictions. This book shows that only about a third of the variation in cross-country changes in exports is explained by wage differences. While wage differences explain some of the production shifts, domestic policies targeting the apparel sector, ownership type, and functional upgrading of the industry also played an important role. Second, changes in exports are usually, but not always, good indicators of what happens to wages and employment. While rising apparel exports correlated with rising wages and employment in the large Asian countries, rising exports coincided with falling employment in Sri Lanka. Third, this book identifies the specific ways that changes in the global apparel market affected worker earnings, thus helping to explain impacts on poverty. Fourth, in terms of policies, the countries that had larger increases in apparel exports were those that promoted apparel sector upgrading; those that did not promote upgrading had smaller increases or even falling exports.

As an important source of income for elderly people, pensions have a great impact on their wellbeing. There are three different pension systems in China (the Old-age Insurance System for Government Agencies and Institutions (OISGAI), the Basic Old-age Insurance System for Urban Employees (BOISUE) and the Social Insurance of the Old-age Pension for Urban and Rural Residents (SIOPURR)). This study empirically analyses the impact of various pension types on the happiness of elderly people in China and further explores the potential impact mechanism using the 2014 China Family Panel Studies data. The study suggests that first, receiving pensions from OISGAI, BOISUE and SIOPURR is positively correlated with the happiness level of elderly people. Second, the sense of happiness of elderly people who receive BOISUE is higher than that of those receiving SIOPURR, which is mainly caused by the difference in the level of pension benefits. When the level of benefits is controlled for, there is no significant difference between these two groups. Third, when they have the same level of pension benefits, the happiness of elderly people who receive OISGAI is significantly higher than that of those who receive pensions from the other two systems, which is possibly related to the hidden ‘special’ government guarantee and the difference of the growth rate of the benefit level.

The objective of the Nepal Investment Climate Assessment (ICA) is to evaluate the investment climate in Nepal in all its dimensions and promote policies to strengthen the private sector. The investment climate is made up of many dimensions that shape the opportunities for investments, employment creation, and growth of private firms. Such dimensions include factor markets, product markets, infrastructure services, and the macroeconomic, legal, regulatory, and institutional framework. The report's key finding is that while there are some niche sectors growing and expanding employment in Nepal (including tourism and certain educational and other services), there are many constraints to the investment climate in Nepal that are hindering the development and growth of the private sector. In particular, political instability, poor infrastructure, poor labor relations, poor access to finance, and declining exports plague Nepal's private sector. To overcome many of these issues and move forward, many reforms are needed. Given the extent of the challenge, effective public-private dialogue is required so that the government and the private sector can work in partnership to address these constraints. The pervasiveness and impact of political instability in Nepal makes the investment climate in the country comparable more to Afghanistan than other countries in the region or the comparator countries used in the analysis. While this comparison is unflattering, it is true. Political instability has stifled growth and limited Nepal's ability to exploit its hydropower and tourism potential. Interestingly, many firms do not perceive access to land and finance as major obstacles. This could be a reflection of lack of dynamism: Nepalese firms are simply not planning to invest, expand, and grow in their unstable and unpredictable environment. The peace dividend is not difficult to measure. As the surveys show, ending civil unrest alone would give back to enterprises 44 working days a year. The effects on economic activity, investment, growth, and job creation could be potentially huge.

All countries in the former transition economies of Central, Eastern, and Southern Europe have undertaken public pension reforms of varying depth and orientation, often with the support of the World Bank. Although the reformed public pension schemes provide broad benefit adequacy, in most cases additional measures are needed to achieve fiscal sustainability in an aging society. 'Adequacy of Retirement Income after Pension Reforms in Central, Eastern, and Southern Europe: Eight Country Studies' assesses the benefit adequacy of the reformed pension systems for eight countries—Bulgaria, the Czech Republic, Croatia, Hungary, Poland, Romania, the Slovak Republic, and Slovenia—to identify policy gaps and options. The authors identify the motivations for reform against the backdrop of the trend toward multi-pillar arrangements, document key provisions, and compare them in the context of the World Bank's five-pillar paradigm for pension reform. They then evaluate the sustainability and adequacy of reformed pension systems and provide recommendations to address gaps and take advantage of opportunities for further reforms. The case studies and summary suggest the following broad policy conclusions: • Fiscal sustainability has improved in most study countries, but few are fully prepared for the inevitability of population aging. • The linkage between contributions and benefits has been strengthened, and pension system designs are better suited to market conditions • Levels of income replacement are generally adequate for all but some categories of workers (including those with intermittent formal sector employment or low lifetime wages), and addressing their needs requires initiatives that go beyond pension policy. • Further reforms should focus on extending labor force participation by the elderly to avoid benefit cuts that could undermine adequacy and very high contribution rates that could discourage formal sector employment. • More decisive financial market reforms are needed for funded provisions to deliver on the expectations of participants and keep funded pensions safe. This book will be of interest to policy makers, researchers, and everyone interested in the topic of pensions in the region, and beyond.

Slow progress in improving the coverage of Latin America and the Caribbean's (LAC's) traditional social protection (SP) programs, combined with the deepening of democracy, have led to calls for a new social contract to provide effective social protection to all citizens. This book highlights the main findings of a regional study by the World Bank, from right to reality: how Latin America and the Caribbean can achieve universal social protection by improving redistribution and adapting programs to labor markets. The report analyzes LAC's social insurance (SI) systems and highlights growing concerns about the incentives they may create and the behaviors they may incite on the part of workers, employers and service providers. It offers an economic analysis of the roots of these problems and suggests a way forward to achieve universal coverage in an equitable manner. The report argues that a coherent overall vision for the SP system should be established if such problems are to be understood and resolved. The goal is to turn the theoretical right to social protection, which is enshrined in many of the region's constitutions and laws, into a reality for all of LAC's population. A central message of the report is that SP systems need to respond to the realities of LAC's labor markets, especially the prevalence of informality and frequent changes of employment.

This study analyzes the performance of social assistance and family benefit programs in eight new member states of the European Union from the perspective of fiscal impact and effectiveness. It is based on household survey data for six of the countries, as well as budget data and information on program design collected at the national level. The paper finds that, although social assistance programs in the new member states are small in terms of coverage and expenditure levels (reaching 2 to 5 percent of the population), the programs are an important safety net for the poor. Programs are relatively well targeted, with between 30 and 60 percent of resources going to the poorest quintile of the population. For those who receive them, benefits can make up as much as 37 percent of average consumption of the poor.

Workers' compensation was arguably the first widespread social insurance program in the United States and the most successful form of labor legislation to emerge from the early Progressive Movement. Adopted in most states between 1910 and 1920, workers' compensation laws have been paving seen as the way for social security, Medicare, unemployment insurance, and eventually the broad network of social welfare programs we have today. In this highly original and persuasive work, Price V. Fishback and Shawn Everett Kantor challenge widespread historical perceptions, arguing that, rather than being an early progressive victory, workers' compensation succeeded because all relevant parties—labor and management, insurance companies, lawyers, and legislators—benefited from the legislation. Thorough, rigorous, and convincing, A Prelude to the Welfare State: The Origins of Workers' Compensation is a major reappraisal of the causes and consequences of a movement that ultimately transformed the nature of social insurance and the American workplace.
