Cash Transfers and Socioeconomic Behavior among Older Adults:,Evidence from a Regression Discontinuity Design

By Anh Tuyet Nguyen & Hiroyuki Yamada The rapid aging of populations has prompted the introduction of social pension programs aimed at preserving the welfare of the elderly. However, adverse socioeconomic behaviors may dampen the intended policy effects. Using a fuzzy regression discontinuity design, this study examines the impact of social pension receipt on expenditure patterns and material hardship among older adults aged 80 year or older in Vietnam. We find that social pension increases the risk of material hardship...

When digital platforms enter informal sectors: work formalization and institutional change

By Isam Faik, Michelle Gwee, Felix Ter Chain Tan, Carmen Leong & Fithra Faisal Hastiadi Digital platforms are undermining long-standing formal institutions for the organization of work. However, when they enter informal sectors, they contribute to the opposite effect by increasing the formalization of work activities. In this study, we investigate this hitherto unexamined phenomenon by drawing on a case study of Gojek, one of the largest digital platforms in Southeast Asia. We identify three main mechanisms through which the...

Access to Pensions, Old-Age Support, and Child Investment in China

By Xiaoyue Shan & Albert Park This work studies how access to public pensions affects old-age support and child investment in traditional societies. Guided by predictions from an overlapping generations model, we analyze the influences of a new pension program in rural China, using a difference-in-differences approach. We find that the program crowds out transfers from working-age adults, especially men, to their elderly parents. Interestingly, the impact on child investment significantly differs by child gender. While adult parents increase educational investment...

The future of public pension provision in the UK: challenges and trade-offs

By Jonathan Cribb , Carl Emmerson & Heidi Karjalainen The UK state pension system faces significant challenges given the country’s ageing population, but at the same time it is crucial for retirement finances: state pensions make up on average almost half of income for recently retired households. Reforms coming into force in 2010 and 2016 have increased universality, and most future pensioners will receive a full (flat rate) state pension. Policy-makers seeking to limit the cost of the system have...

Heterogeneous Institutional Investor Response to Firm Environmental Regulatory Risk

By Chunxiao Lu, Yuyang Zhang & Linxiang Ma This paper investigates whether institutional investors incorporate firm-level environmental regulatory risk into their portfolio decisions. We document substantial heterogeneity across investor types in their responses to changes in firm-level environmental regulatory risk. Long-horizon investors, such as banks, insurance companies, and pension funds, tend to tilt their portfolios toward stocks with higher environmental regulatory risk. In contrast, short-horizon investors, including investment advisors and mutual funds, reduce their holdings of these firms. These opposing...

Social Security Reforms and Inequality among Older Workers in Spain

By Cristina Bellés-Obrero, Manuel Flores, Pilar Garcia-Gomez, Sergi Jimenez-Martin & Judit Vall Castelló This chapter studies social security reforms and trends in inequalities among older workers over the last decades in Spain. Its main goal is to analyze the redistributive impact of the various pension reforms on older income inequality. Compared to the rules in 1985, recent pension reforms have led to an average increase on Social Security Wealth of approximately 18,000€ for men and 15,000€ for women. This represents...

Public pensions and family dynamics: Eldercare, child investment, and son preference in rural China

By Naijia Guo, Wei Huang & Ruixin Wang Using variations in the timing of the New Rural Pension Scheme (NRPS) across rural Chinese counties, we examine its effects on eldercare mode, child investment, and son preference. Our findings are three-fold: (1) After the introduction of NRPS, married sons are less likely to live with and provide care for their parents, while married daughters show no significant change in their caregiving behavior; (2) Parents reduce the brideprice for their sons but not the dowry...

Lost Pensions, Lost Pensioners: Is a National Registry of Pension Plans the Answer?

By David P. Blake & John A. Turner In the United States and other countries, many retirees face great difficulties in tracing their former employers in order to apply for a pension to which they are entitled. At the same time, pension plans have trouble tracking down pensioners with whom they have lost contact. The problem of lost pensions and lost pensioners was also prevalent in the United Kingdom, but in 1991 the British government established a national registry of...

European Financial Ecosystems. Comparing France, Sweden, UK and Italy.

By Stefano Caselli & Marta Zava The study examines the structure, functioning, and strategic implications of financial ecosystems across four European countries-France, Sweden, the United Kingdom, and Italy-to identify institutional best practices relevant to the ongoing transformation of Italy's financial system. Building on a comparative analysis of legislation and regulation, taxation, investor bases, and financial intermediation, the report highlights how distinct historical and institutional trajectories have shaped divergent models: the French dirigiste system anchored by powerful state-backed institutions and deep...

Labor Supply and Savings Responses to Increasing the Pension Eligibility Age in South Korea

By Janghyeok An, Devon Gorry & Jonathan M. Leganza We study how South Koreans responded to an increase in the full pension eligibility age. Using a regression discontinuity design, we document the causal effects of the change on several potential margins of adjustment. We find clear evidence of delayed benefit claiming, consistent with studies in other settings. However, we find little to no statistical evidence of changes in labor supply, in contrast with previous literature. We also find no changes...
