Essays in health economics
(2023) Meng, Fan; Sousa-Poza, Alfonso
As the global economy and healthcare evolve, subjective well-being is increasingly becoming a topic of interest in the field of health economics. In this dissertation, we try to investigate subjective well-being from two related aspects: obesity and marriage. Obesity is a global health crisis that has reached alarming proportions in recent years. Defined as an excessive accumulation of body fat, obesity has far-reaching implications for both individ- ual health and society as a whole. Its prevalence has steadily risen, with over 650 million adults worldwide classified as obese, according to data from the World Health Organization (WHO). This epidemic has led to a surge in obesity-related health problems, including diabetes, cardio- vascular disease, and certain types of cancer, making it a pressing concern for healthcare systems and policymakers. Estimates of the cost of obesity are an important basis for the development and evaluation of obesity-related policies. Previous studies have estimated the direct and indirect costs of obesity, but in addition to these, the intangible costs of obesity are also noteworthy. The intangi- ble costs of obesity are associated with a loss of well-being. In addition, obesity-related inequality may also combine with peer effects to lead to lower well-being in obese individuals. So, ignoring the intangible costs of obesity may lead to underestimating the benefits of obesity control policies. Marriage, without a doubt, is a major event in life. People from almost any socio-cultural back- ground consider marriage-related decisions such as whether to get married, when to get married, and with whom to get married. But nowadays, in increasingly countries around the world, mar- riage rates continue to decline and the age of first marriage continues to be delayed, so we sought to analyze whether these trends are related to marriage-related well-being. The contributions of each chapter are shown below: Chapter 2 uses SOEP 2002-2018 data and a life satisfaction-based compensation approach to quantify the intangible costs of overweight and obesity. Previous literature documents the direct and indirect economic costs of obesity, yet none has attempted to quantify the intangible costs of obesity. This study focuses on quantifying the intangible costs of one unit body mass index (BMI) increase and being overweight and obese in Germany. Our results underscore how existing research into obesity’s economic toll may underestimate its true costs, and they strongly imply that if obesity interventions took the intangible costs of obesity into account, the economic benefits would be considerably larger. Chapter 3 uses data from the German Socio-Economic Panel (GSOEP), investigates the changes in the BMI distribution and obesity inequality among German adults aged 18+ between 2002-2018 and estimates the relationship between obesity inequality and subjective well-being. The results show that the rise in obesity prevalence is mainly due to an overall rightward shift of the BMI distribution, accompanied by an increase in left skewness. Over the entire 16-year period, obe- sity inequality increased significantly, especially among females, those with low education levels, and low-income groups. The results also document a significant association between different measures of obesity inequality and subjective well-being, especially among women. Chapter 4 explores the trends in the subjective well-being (SWB) of never-married people (referenced with the married) and the factors that account for the gaps in SWB between never- married and married people. By employing a harmonized data from surveys conducted in six distinct countries, namely Australia (HILDA), South Korea (KLIPS), Russia (RLMS), Switzerland (SHP), Germany (SOEP), and the United Kingdom (BHPS and UKHLS), our analysis discerns a consistent and statistically significant association between never-married status and lower levels of life satisfaction, a relationship that has exhibited no substantial alteration over time. Particularly noteworthy is the discernible reduction in life satisfaction among never-married individuals in South Korea in comparison to their married counterparts. The thesis concludes with a short summary in chapter five.
A multifaceted analysis of Myanmar’s rice sector: gender perspectives, international competitiveness, and farmers’ emotional well-being
(2025) Chan, Nandar Aye; Zeller, Manfred
The agricultural sector is vital to Myanmar’s economic development, food security, and poverty reduction. However, recent global shifts in commodity markets, combined with local crises such as climate change, the COVID-19 pandemic, conflicts, economic instability, and rising fertilizer prices and operational costs, have significantly affected Myanmar’s agri-food sector. These challenges threaten the performance of the agricultural sector, particularly the rice sector, which is essential for many livelihoods, rural employment, and export earnings. The sector faces declining productivity, reduced incomes, rising debt burdens, and increased vulnerability, especially among smallholder farmers, including women. Therefore, the Ministry of Agriculture, Livestock, and Irrigation (MOALI) is dedicated to strengthening the rice sector through promoting inclusive gender roles, enhancing competitiveness in the domestic and international rice markets, and safeguarding the socio-economic well-being of all farmers. Addressing Myanmar’s key agricultural challenges and aligning with the objectives of MOALI, this dissertation investigates three critical areas (Chapters 2 to 4) to make a modest knowledge contribution to the sustainability and long-term development of the country’s rice sector. Despite government initiatives and extensive research on Myanmar’s rice sector, three important aspects remain underexplored: the gender gap in productivity, cost competitiveness, and the role of productivity in mediating shocks to farmers’ well-being. Specifically, this dissertation has three main objectives: 1) to estimate the magnitude of the gender gap in rice productivity and identify the factors contributing to this gap; 2) to analyze the cost competitiveness of rice production by examining production costs, cost efficiency, and the potential effect of improving cost efficiency on the country’s global competitiveness; and 3) to examine the effects of shocks on farmers’ well-being and explore how rice productivity mediates this relationship. Understanding these issues is crucial for designing policies that improve the performance of Myanmar’s rice sector and strengthen farmers’ resilience. The dissertation employs a quantitative approach, using household survey data and other secondary data sources. Particularly, data for Chapters 2 and 3 originate from the 2014 Area-Based Farm Household Survey in the Ayeyarwady Delta Region, administered by the International Rice Research Institute (IRRI) under the Metrics and Indicators for Tracking in the Global Rice Science Partnership project. Chapter 3 also incorporates nationwide phone survey datasets, including the Myanmar Household Welfare Survey (MHWS) and the Myanmar Agricultural Performance Survey (MAPS), conducted by the International Food Policy Research Institute (IFPRI) during 2021-2022. This cumulative dissertation consists of five chapters. Chapter 1 presents the introduction. Chapter 2 examines the gender gap. Chapter 3 focuses on the cost competitiveness of Myanmar’s rice sector. Then, Chapter 4 investigates the mediating role of rice productivity in the shocks-happiness relationship, and Chapter 5 concludes the dissertation and provides policy recommendations. Chapter 2 presents an analysis of the gender productivity gap in Myanmar’s rice sector. The analysis focuses on the Ayeyarwady Delta region, one of the three major agroecological zones for rice cultivation in Myanmar, using IRRI regional plot-level data. The study addresses seasonal variation and assesses jointly managed plots. The Oaxaca-Blinder mean decomposition approach is used to identify the causes of gender differences in monsoon and summer paddy productivity. The empirical findings show that women managers are 7 percent less productive than men in monsoon paddy production, with 95 percent of this gap explained by structural effects. Plots jointly managed by women and men outperform those managed by either women or men alone in summer paddy production. The results show that seasonality affects the disparity in gender productivity. Divorced women account for a large portion of the productivity differential among non-married women managers. Initiatives to eliminate the gender yield gap in Myanmar should pay attention to the unique requirements and obstacles that women encounter throughout different seasons and tailor their interventions accordingly. Chapter 3 conducts a comparative analysis of production costs among major rice-producing countries and estimates the cost efficiency of rice farming in Myanmar using a stochastic frontier cost function model. Moreover, this study examines the link between cost efficiency and domestic resource costs (DRC), a key indicator of global competitiveness in rice production. The study also considers the seasonal variations in Myanmar during both the dry and wet seasons. The findings show that Myanmar ranks as the second least expensive rice-producing country among selected Asian countries. The mean cost efficiencies are 89% and 86% for the dry and wet seasons, respectively. Both dry and wet seasons of rice production demonstrate a comparative advantage. The results also show that cost efficiency positively contributes to global competitiveness in both seasons. Focusing on education, farm size, seed procurement strategies, and training programs can increase cost efficiency, thereby further improving global competitiveness in rice production. Chapter 4 examines the effects of shocks on farmers’ happiness in Myanmar and explores the mediation role of rice productivity in this relationship. The study uses nationwide phone survey datasets from Myanmar, provided by the IFPRI, specifically focusing on the rice sector to assess productivity. The study applies the mediation analysis outlined by Acharya et al. (2016) and estimates the average controlled direct effect (ACDE) of shocks while accounting for rice productivity as a mediator. To ensure robustness, additional causal mediation analysis is employed. The results indicate that rice productivity partially mediates the shock-happiness relationship. This suggests that shocks influence happiness through additional pathways beyond productivity. Moreover, farmers’ happiness is more directly influenced by recent productivity than by past agricultural performance. However, past shocks continue to have a significant and lingering effect on their happiness. These findings highlight the need for policymakers to mitigate the impact of shocks on well-being not only by improving rice productivity but also by addressing other factors that influence farmers’ happiness. The findings of this dissertation contribute to the literature on the development of Myanmar’s rice sector. Firstly, providing the first empirical evidence of the gender gap in productivity can help inform targeted policy interventions to increase rice productivity while addressing the specific needs of men and women in rice production. Secondly, it provides scalable insights to promote the competitiveness, sustainability, and efficiency of rice production, which not only benefits Myanmar but also contributes to the broader global rice market. Finally, given the importance of understanding the relationship between shocks and well-being through rice productivity, this insight provides valuable guidance for designing interventions to strengthen productivity and improve well-being in vulnerable agrarian communities facing climate-related shocks. All these chapters contribute to the understanding of seasonality, which is vital for highlighting the importance of seasonal production dynamics in Myanmar’s rice sector. Overall, Myanmar’s rice sector can achieve greater sustainability and development by promoting gender equality, enhancing competitiveness, and supporting resilience-building measures for rice-farming communities, ultimately improving farmers’ well-being.
The economics of elderly care
(2015) Bauer, Jan Michael; Sousa-Poza, Alfonso
Longer life expectancy and low fertility rates increase the share of elderly among the population of most industrialized countries. This demographic change affects the economy and the society and is most likely to proceed in the future. Therefore, policy makers and families need to be aware of the implications associated with an aging population. One particularly great challenge comes with the rising number of fragile elderly people, for which most countries are currently unable to provide sufficient care solutions. Germany, for instance, is facing a constantly rising share of people in need that mostly receive informal care from friends and family. Public support promotes these informal care arrangements (§3 SGB XI) and endorses care receivers to remain in their domestic environment. Even though such informal care arrangements are preferred by most families, caregiving can have a large impact on the caregiver’s life. Policy makers need to measure and incorporate these outcomes in order to provide suitable aid for caring families and, thereby, ensuring sustainable and dignified population aging. This dissertation consists of three academic papers and contributes to the topic in several ways: the first paper reviews the recent literature on the effects of informal caregiving on the caregiver and, thereby, assesses the opportunity costs associated with informal care provision. Further, we evaluated the methodology that is commonly used and identify certain risk groups as well as arrangements that are particularly burdensome. The second paper takes a specific look at the subjective well-being of caregivers in Germany and analyzes effects associated with providing care. In contrast to most prior studies, the paper uses large population-based longitudinal data, accounts for unobserved heterogeneity, and estimates the relationship with different methodologies. The paper further values well-being losses monetarily, which allows a comparison to formal care alternatives. The third paper provides new insights on individual selection behavior in the market for supplemental health insurances. This is an increasingly popular way to insure against long-term care needs, a risk not fully covered despite a statutory long-term care insurance. Private insurance markets are fragile in the presences of asymmetric information and, therefore, might not be a sustainable solution to cover the increasing risks of an aging society. We developed an innovative approach to disentangle different selection behaviors in a heterogeneous sample and identify asymmetric information exemplarily for the market of supplemental dental insurance, despite no risk-coverage correlation for the aggregated sample.
