The Price Elasticity Of African Elephant Poaching, Quy-Toan Do, Andrei A. Levchenko, Lin Ma, Julian Blanc, Holly Dublin, Tom Milliken

Research Collection School Of Economics

The objective of this paper is to provide an estimate of the elasticity of elephant poaching with respect to prices. Ivory being a storable commodity subjects its price to Hotelling’s no-arbitrage condition, hence allowing identification of the supply curve. The price of gold, one of many commodities used as stores of value, is thus used as an instrument for ivory prices. The supply of illegal ivory is found to be price inelastic with an elasticity of 0.4, with changes in consumer prices passing-through to prices faced by producers at a rate close to unity. Estimations based on a number of …

Social Norms And Fertility, Sunha Myong, Junghae Park, Junjian Yi

Research Collection School Of Economics

We document three stylized facts on marriage and fertility patterns in East Asian societies: (i) their marriage rates are among the highest in the world, but their total fertility is the lowest; (ii) although they have the lowest total fertility, almost all married women have at least one child; and (iii) almost no single women have any children. As these societies have been influenced by Confucianism over millennia, marriage and fertility decisions are potentially shaped by two social norms: the unequal gender division of childcare and the stigma attached to out-of-wedlock births. We present a model incorporating the two social …

Providing Childcare, Christine Ho, Sunha Myong

Research Collection School Of Economics

Women’s economic empowerment has been hailed as one of the most remarkable revolutions in the past 50 years. Yet, women still face the lion’s share of the burden of childcare despite major progress in their education and earnings capacity. This is particularly salient in many Asian countries. This chapter proposes a synthesis of the state of knowledge on childcare and discusses policy-relevant issues applicable to the Singapore context. Selected policies are documented and lessons from the international landscape are discussed. Raising children incurs both direct costs in the form of childcare and opportunity costs in the form of career costs. …

Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young

Faculty & Staff Research and Creative Activity

It well known that palatability and nutritional quality of foods and/or diets are viewed as being in tension with one another. While there exist multiple measures of healthiness, there are no such measures for tastiness. This gap limits the degree to which researchers can investigate this tension and its implications for dietary behavior and hence public health and nutrition policy. The scope of future work concerning the dietary behavior of Americans would expand greatly if researchers better understood consumers’ willingness to eat certain foods, which matters as much as recommending those foods for them to eat in the first place. …

The Effects Of Recent Minimum Wage Increases On Self-Reported Health In The United States, Liam Sigaud

Electronic Theses and Dissertations

A sharp income-health gradient exists in the United States. Lower levels of income are associated with higher rates of mortality, morbidity, and risky health behaviors, as well as decreased access to health care. Growing evidence of a causal link between income and health suggests that government income-support policies may be an effective strategy for improving health outcomes among poor Americans. One such policy – the minimum wage – has experienced a surge in popularity in recent years. In 2019, twenty-five states and the District of Columbia increased their minimum wage, up from only eight states in 2011. Yet the literature …

The Heterogeneous Impacts Of Natural Disasters On Risk Preferences In Indonesia, Helene Purcell

Population Center Working Papers (PSC/PARC)

Many economic decisions are influenced by individual risk preferences, and new evidence challenges the immutability of these preferences. This paper explores the impact of disasters on individual risk attitudes using longitudinal data from Indonesia, focusing on the heterogeneity of disasters by type, severity and timing. I find risk aversion increases for a decade following disasters, and high-mortality disasters, namely earthquakes, are more salient to individuals than higher frequency, lower-mortality disasters. These outcomes shed light on how survivors in a developing country respond to and internalize disaster shocks and are informative to policymakers in addressing the increasing threat of disasters.

“Why Am I The Only One Responsible For The Whole Family?”: Expressions Of Economic Filial Piety And Financial Anxiety Among Female Survivors Of Sex Trafficking In Cambodia, Julia M. Smith-Brake, Lim Vanntheary, Nhanh Channtha

Dignity: A Journal of Analysis of Exploitation and Violence

Filial piety has evolved and spread in different ways throughout Asia, with the common thread of deep respect and gratitude towards one’s parents remaining a very strong cultural value. In Khmer culture, filial piety includes the expectation that daughters and daughters-in-law provide daily assistance to parents and parents-in-law. Financial anxiety includes the worry and negative mental health outcomes associated with financial stressors. This article presents findings from the Butterfly Longitudinal Research Study on themes on filial piety and financial anxiety, combining survey results from across multiple years as well as a thematic analysis of themes from focus group discussions and …

The Asymmetric Effect Of Sentiment On Equity Returns, Mishal Ahmed

Dissertations

In the first chapter titled “The Asymmetric Effect of Sentiment on U.S. Equity Returns”, we test the asymmetric impact of investor sentiment, proxied by the Baker-Wurgler (2007) investor sentiment index, on expected stock returns in the U.S. We regress sentiment on market and economy-wide fundamentals, use the residuals as a measure of excess sentiment and estimate long-horizon return regressions using positive and negative components of excess sentiment as predictors. We hypothesize that excessive optimism leads investors to make significant portfolio changes whereas excessive pessimism makes investors more cautious about investing, due to loss aversion. Primary results confirm our hypothesis with …

The researcher reached to a mathematical model consisting …

Obstacles To Dieting Behavior, Shahram Heshmat

Journal of Food Law & Policy

Despite documented short term success, dieting has a very low success rates, most dieters regain their weight back within 3-5 years. The question is why do people fail to stick to their goal for eating a healthy diet in order to lose weight? One possible answer is that people have self-control problems in the form of a present-biased preference. From a prior perspective, they want to behave relatively patiently, but as the moment of action approaches, they want to behave relatively impatiently. The essay presents some insights from behavioral economics to explain why people fail to maintain healthy behavior.

Emotional Finance: The Impact Of Emotions On Investment Decisions, Leef H. Dierks, Sonja Tiggelbeck

Journal of New Finance

Emotions have a decisive influence on individual investment decisions and thus on market developments. Collective behavior, which often prevails in markets, can trigger the development of speculative bubbles as, more often than not, investors rely on trust in an attempt to reduce the uncertainty and complexity prevailing in markets. Based on the developments surrounding German financial services provider Wirecard in 2020, this contribution explains why retail and institutional investors decided to trust the company's narrative in an attempt to reduce uncertainty, despite increasingly obvious large-scale accounting inconsistencies.

All signs point to an uncertain path for inflation in the future. While inflation is set to stay prospectively higher in the US in the near-term, it's unlikely to remain so.

Information Avoidance And Medical Screening: A Field Experiment In China, Yufeng Li, Juanjuan Meng, Changcheng Song, Kai Zheng

Research Collection Lee Kong Chian School Of Business

Will individuals, especially high-risk individuals, avoid a disease test because of information avoidance? We conduct a field experiment to investigate this issue. We vary the price of a diabetes test (price experiment) and offer both a diabetes test and a cancer test (disease experiment) after eliciting participants’ subjective beliefs about their disease risk. We find evidence that, first, some people avoid the test even when there is neither a monetary nor a transaction cost, and second, both low- and high-risk individuals select out of the test as the price increases. We explain our findings using three classes of models of …

Intra-Firm Hierarchies And Gender Gaps, Nicolo Dalvit, Aseem Patel, Joanne Tan

Research Collection School Of Economics

We study how changes in female representation at the top of a firm’s organisation affect gender-specific outcomes across hierarchies within firms. We start by developing a theoretical model of a hierarchical firm, where gender representation in top organisational layers can affect gender-specific hiring and promotion probabilities at lower layers. We then exploit a recent French reform that imposed gender representation quotas in the boards of directors and test the model’s predictions in the data. Our empirical results show that the reform was successful in reducing gender wage and representation gaps at the upper layers of the firm, but not at …

Three Essays On Learning And Conflict Applied To Developing Countries, Amal Ahmad

Doctoral Dissertations

This dissertation uses microeconomics to study questions of learning and conflict in developing countries. The first essay studies how much rural producers in developing countries can learn from their own experience to redress important information gaps about their crop. It builds a theoretical model of learning from experience and applies it using a rich dataset on cotton farmers in Pakistan. I test whether farmers learn from cultivation experience about the pest resistance of their seeds and use this information to improve selection and productivity. I find no such learning effect and this conclusion is robust to several parameters that could …

Student Loans And Health-Related Financial Hardship, Sophia T. Anong, Robin Henager

Journal of Student Financial Aid

Research has shown that student loan borrowers in repayment exhibit physical and mental health problems. These can be exacerbated by and contribute to health-related financial hardship. We use the 2015 U.S. National Financial Capability Study to examine the likelihood of having past due medical bills and of avoiding health care services by not purchasing prescribed medication, skipping tests or follow-up with a doctor or not seeking care for a medical problem. Borrowers on income-driven repayment plans and those who made late payments are found to be more likely to have unpaid medical bills and to have avoided required medical attention. …

The Cost Of Subway Delays: A Counterfactual Welfare Analysis Of Boston’S T, Adam Dean

Dartmouth Undergraduate Journal of Politics, Economics and World Affairs

Boston’s subway system, the T, is an important artery for transportation in and around the city. However, it is the oldest subway system in the United States, and, as a result, is in dire need of upgrades. This paper employs a welfare analysis to calculate the economic cost of the T’s lack of reliability, while also comparing the T’s reliability rate to other transit systems around the world. With a counterfactual estimate of a 95 percent reliability rate versus the pre-pandemic 88.47 percent reliability rate, the difference in welfare is found to be between $54 million and $163 million annually. …
