In the context of the second demographic transition many countries consider natalistic policies as a hopefully viable solution to the fiscal pressure stemming from longevity and declining fertility. However, an increased number of births implies immediate economic costs and delayed economic gains, whereas a quantification of the net effects remains a challenge. We propose a method to quantify the effects of increased birth rates, by the means of an overlapping generations model with a rich family structure. We analyze the overall macroeconomic and welfare effects as well as distribution of these effects across cohorts and study the sensitivity of the final effects to the assumed target value and path of increased fertility. We find that fiscal effects are positive, but even in the case of relatively large fertility increase they are small. The sign and the size of both welfare and fiscal effects depend substantially on the patterns of increased fertility: if increased fertility occurs via lower childlessness, the fiscal effects are smaller and welfare effects are more likely to be negative than in the case of the intensive margin adjustments.

1. The document evaluates the welfare and economic effects of raising fertility through natalist policies.
2. It finds small, positive fiscal effects from increased fertility but negative welfare effects, as higher fertility lowers wages and raises pension benefits slightly.
3. The effects of intensive versus extensive fertility increases on outcomes are mixed but small, explaining mixed empirical findings on previous policy interventions.

In the context of the second demographic transition, many countries consider rising fertility through pro-family polices as a potentially viable solution to the fiscal pressure stemming from longevity. However, an increased number of births implies private and immediate costs, whereas the gains are not likely to surface until later and appear via internalizing the public benefits of younger and larger population. Hence, quantification of the net effects remains a challenge. We propose using an overlapping generations model with a rich family structure to quantify the effects of increased birth rates.

Statistical gender discrimination: evidence from young workers across four de...GRAPE
Statistical discrimination at young age due to fertility expectations may decrease as the average age of first birth increases. The authors analyze data from 56 countries over four decades to test whether changes in the timing of fertility are linked to changes in adjusted gender wage gaps for labor market entrants aged 20-30. They estimate adjusted gender wage gaps and instrument for fertility timing using reforms to compulsory education, military conscription policies, and the authorization of contraceptive pills across countries over time.
This document summarizes research on mapping the demand and supply of social work placements in New Zealand. It discusses conducting a survey of institutions providing social work education and analyzing data from the Social Workers Registration Board. The research aims to quantify placement demand, clarify quality issues, and innovate new placement models. So far, the survey found that over half of placements are with non-government agencies, and government placements are more likely to have on-site and registered social work supervision. The research faces challenges in analyzing the Registration Board's data and suggests an alternative data collection format. Open questions consider how to improve the balance and quality of placement opportunities.

This document summarizes efforts to improve the Women's Empowerment in Agriculture Index (WEAI) by discussing various studies and initiatives. It provides an overview of the different versions of the WEAI (original, abbreviated, project-specific, and value chain-specific) and how the index is constructed. It also shares key findings from applying the WEAI in multiple countries, such as workload and access to credit being common constraints. Additionally, it discusses preliminary results from a Philippines pilot that identify workload and group membership as top disempowerment factors. The document demonstrates how the WEAI can inform programming to empower women, using Bangladesh's ANGeL project as an example.

The workshop closely focused on building National Adaptation Plans in the agricultural sector through multi-stakeholder collaboration, and increased knowledge and capacity on a number of topics including: prioritization of adaptation options, cost-benefit analysis, overview of the broad-based nature of climate change adaption impacts, analysis of challenges, and creation of an open discussion with key stakeholders on defining a road-map for the NAP process. The workshop was delivered using discussions and case studies to enhance interactive learning for participants, with supporting presentations by GiZ and SNV.
Introduction to Factor Analysis for and With Mixed Methods: British Academy ...Wendy Olsen
In this presentation, we set up the aims and mechanisms of the Workshop on Integrated Mixed Methods Research held at University of Manchester (Nov. 3, 2014); it specifically focuses on Factor Analysis, which creates a scale for a gender norm about labour markets. We show how a classical scale and a factor are similar, how they relate to regression and to labour supply, and how NVIVO can be used to follow up a mixed methods workshop or focus group. This creates a mixed-methods approach to gender norms in the labour market. Quite original and very promising. The workshop was a huge success running from 10 am to 3 pm following by an extra hour discussing how this leads to possible research opportunities.
This document discusses three "holy grails" of improving social impact: 1) defining outcomes, 2) measuring and transparently reporting outcomes to change resourcing decisions, and 3) collaborative and participative approaches. It argues that without clear outcomes, effective measurement, and collaboration across sectors, the social impact system will not be able to meet future challenges. Measurement is valuable for focusing organizations on outcomes and allowing funders to reallocate resources, but barriers include costs, timeframes, and lack of agreement on methods. The document advocates for defining shared outcomes, shared measurement, open data, long-term collaborative approaches, and a learning system oriented toward community outcomes rather than individual programs.
4 Flexible Strategies and the Credible Attribution Challenge in Complex Conte...The Impact Initiative
This document describes an action research case study that developed and piloted a qualitative impact assessment protocol (QuIP) to evaluate the impact of rural livelihood projects in complex contexts across Africa. The QuIP was designed to provide credible attribution by systematically collecting qualitative evidence on how project interventions contributed to outcomes, while also exploring other drivers of change. The case study projects focused on value chains, climate resilience, and diversification across Malawi and Ethiopia. Results showed some positive impacts on incomes and food security from training and inputs, but impacts varied between locations and were often constrained by weather and other contextual factors. The methodology combined quantitative monitoring with qualitative interviews to explore causal mechanisms and triangulate findings.
The document provides an overview and methodology for the evaluation of the Improving Futures programme, which aims to improve outcomes for children in families with multiple and complex needs. It discusses the evaluation framework, data collection methods including a secure online system to monitor outcomes, and analysis to identify typologies of families. Early findings show projects establishing partnerships and support for families, with some early positive outcomes observed. Key implications for future programmes are also summarized.
Women’s Empowerment in Agriculture and Nutritional Outcomes in Ethiopiaessp2
1) The study examines the impact of women's empowerment in agriculture on nutritional outcomes in Ethiopia using data from 5 regions.
2) It finds that women in Ethiopia have relatively low empowerment levels compared to other countries, with the largest contributions to disempowerment coming from leadership, time, and resource domains.
3) Regression analysis shows that women's empowerment, as measured by the WEAI index, has a positive impact on children's dietary diversity and stunting as well as women's dietary diversity. Having more say in credit decisions and income also leads to better nutritional outcomes.

Women’s Empowerment in Agriculture and Nutritional Outcomes in Ethiopiaessp2
Women's empowerment in agriculture is examined in relation to nutritional outcomes for women and children in rural Ethiopia. Using survey data, women are found to have low empowerment levels according to the Women's Empowerment in Agriculture Index (WEAI), with the largest constraints in leadership, time, and resources. Regression analysis indicates that greater women's empowerment, such as through group membership, work hours, and income control, is positively associated with reduced stunting and underweight in children as well as higher dietary diversity and BMI in women. Other factors like wealth, livestock ownership, and crop diversity also influence nutritional levels. The study concludes that empowering women in different domains can help improve nutrition.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.

Demographic transition and the rise of wealth inequalityGRAPE
We study the contribution of rising longevity to the rise of wealth inequality in the U.S. over the last seventy years. We construct an OLG model with multiple sources of inequality, closely calibrated to the data. Our main finding is that improvements in old-age longevity explain about 30% of the observed rise in wealth inequality. This magnitude is similar to previously emphasized channels associated with income inequality and the tax system. The contribution of demographics is bound to raise wealth inequality further in the decades to come.
(Gender) tone at the top: the effect of board diversity on gender inequalityGRAPE
The research explores to what extent the presence of women on board affects gender inequality downstream. We find that increasing presence reduces gender inequality. To avoid reverse causality, we propose a new instrument: the share of household consumption in total output. We extend the analysis to recover the effect of a single woman on board (tokenism(
Gender board diversity spillovers and the public eyeGRAPE
A range of policy recommendations mandating gender board quotas is based on the idea that "women help women". We analyze potential gender diversity spillovers from supervisory to top managerial positions over three decades in Europe. Contrary to previous studies which worked with stock listed firms or were region locked, we use a large data base of roughly 2 000 000 firms. We find evidence that women do not help women in corporate Europe, unless the firm is stock listed. Only within public firms, going from no woman to at least one woman on supervisory position is associated with a 10-15% higher probability of appointing at least one woman to the executive position. This pattern aligns with various managerial theories, suggesting that external visibility influences corporate gender diversity practices. The study implies that diversity policies, while impactful in public firms, have limited
effectiveness in promoting gender diversity in corporate Europe.
This document introduces a framework for analyzing contracts between a principal and multiple agents who have interdependent preferences. It begins with a simple example involving two agents who can choose between working and shirking, and whose outputs are either success or failure. The agents have interdependent utility that depends on both their own material payoff and their conjecture of the other agent's utility.
The document then outlines the research agenda, which is to characterize optimal contracts when agents have interdependent preferences and to provide recommendations for contract design based on whether preferences are positively or negatively interdependent. Finally, it presents some general results, finding that independent contracts are no longer optimal when preferences are interdependent, and that contracts should incorporate both individual performance bonuses and team
Tone at the top: the effects of gender board diversity on gender wage inequal...GRAPE
We address the gender wage gap in Europe, focusing on the impact of female representation in executive and non-executive boards. We use a novel dataset to identify gender board diversity across European firms, which covers a comprehensive sample of private firms in addition to publicly listed ones. Our study spans three waves of the Structure of Earnings Survey, covering 26 countries and multiple industries. Despite low prevalence of female representation and the complex nature of gender wage inequality, our findings reveal a robust causal link: increased gender diversity significantly decreases the adjusted gender wage gap. We also demonstrate that to meaningfully impact gender wage gaps, the presence of a single female representative in leadership is insufficient.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large New Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economies, we use this model to provide comparative statics across past and contemporaneous age structures of the working population. Thus, we quantify the extent to which the response of labor markets to adverse TFP shocks and monetary policy shocks becomes muted with the aging of the working population. Our findings have important policy implications for European labor markets and beyond. For example, the working population is expected to further age in Europe, whereas the share of young workers will remain robust in the US. Our results suggest a partial reversal of the European-US unemployment puzzle. Furthermore, with the aging population, lowering inflation volatility is less costly in terms of higher unemployment volatility. It suggests that optimal monetary policy should be more hawkish in the older society.
This document discusses how labor market inequality may push disadvantaged groups like women into entrepreneurship out of necessity. It presents a theoretical framework showing how greater gender employment gaps could increase the prevalence of female self-employment. The authors test this using data on gender wage and employment gaps matched with survey data on entrepreneurship. Their results show a robust positive effect of gender employment gaps on necessity-driven female entrepreneurship but little effect of wage gaps. This provides empirical support that labor market discrimination can push disadvantaged groups into self-employment when other employment options are limited.
Evidence concerning inequality in ability to realize aspirations is prevalent: overall, in specialized segments of the labor market, in self-employment and high-aspirations environments. Empirical literature and public debate are full of case studies and comprehensive empirical studies documenting the paramount gap between successful individuals (typically ethnic majority men) and those who are less likely to “make it” (typically ethnic minority and women). So far the drivers of these disparities and their consequences have been studied much less intensively, due to methodological constraints and shortage of appropriate data. This project proposes significant innovations to overcome both types of barriers and push the frontier of the research agenda on equality in reaching aspirations.
Overall, project is interdisciplinary, combining four fields: management, economics, quantitative methods and psychology. An important feature of this project is that it offers a diversified methodological perspective, combining applied microeconometrics, as well as experimental methods.
- The document discusses the optimal assignment of property rights when a social planner cannot commit to future trading mechanisms. This lack of commitment results in ex-post inefficiency and inefficient investment decisions due to hold-up problems.
- The social planner chooses property rights to alleviate these frictions. The paper proposes a framework to characterize the optimal property right using a mechanism design approach. The main result is that the optimal property right is simple but flexible, often featuring an option to own the property.
The document presents a framework for studying the optimal design of contractual property rights using mechanism design. It discusses how property rights determine agents' outside options in economic interactions and impact ex-post efficiency and investment incentives when the social planner cannot commit to future mechanisms. The authors analyze how to design property rights to alleviate these frictions in a setting with one-sided private information and bargaining power. A key result is that the optimal property right is often simple but flexible, featuring an option to own the resource.

"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.

In a tight labour market, job-seekers gain bargaining power and leverage it into greater job quality—at least, that’s the conventional wisdom.
Michael, LMIC Economist, presented findings that reveal a weakened relationship between labour market tightness and job quality indicators following the pandemic. Labour market tightness coincided with growth in real wages for only a portion of workers: those in low-wage jobs requiring little education. Several factors—including labour market composition, worker and employer behaviour, and labour market practices—have contributed to the absence of worker benefits. These will be investigated further in future work.
