Undominated Mechanisms, Tilman Borgers, Jiangtao Li, Kexin Wang

Research Collection School Of Economics

We study the design of mechanisms when the designer faces multiple plausible scenarios and is uncertain about the true scenario. A mechanism is dominated by another if the latter performs at least as well in all plausible scenarios and strictly better in at least one. A mechanism is undominated if no other feasible mechanism dominates it. We show how analyzing undominated mechanisms could be useful and illustrate the tractability of characterizing such mechanisms. This approach provides an alternative criterion for mechanism design under non-Bayesian uncertainty, complementing existing methods.

Do Search Costs Explain Persistent Investment In Active Mutual Funds?, Aljoscha Janssen, Jurre Thiel

Research Collection School Of Economics

Active funds, though losing market share since the 1990s, make up nearly half of all mutual funds but charge more without better performance. We analyze fund data and a search model, highlighting the impact of search costs and active fund preferences. From 1993 to 2018, reduced search costs expanded the market and heightened competition, while a preference shift from active to passive funds increased the latter's market share. However, investors who choose active funds, facing higher search costs, and continue to show a strong preference for them, allow these funds to keep charging higher fees.

Technifying Ventures, Yoshiki Ando, Emin Dinlersoz, Jeremy Greenwood, Ruben Piazzesi

Research Collection School Of Economics

How do advanced technology adoption and venture capital (VC) funding impact employment and growth? An analysis of data from the US Census Bureau suggests that while both advanced technology use and VC funding matter on their own for firm outcomes, their joint presence is most strongly correlated with higher employment levels. VC presence is linked with a high increase in employment, though primarily among a limited subset of firms. In contrast, technology adoption is associated with a smaller rise in employment, yet it influences a considerably larger number of firms. A model of startups is created, focusing on decisions to …

The Rising Returns To R&D: Ideas Are Not Getting Harder To Find, Yoshiki Ando, James Bessen, Xiupeng Wang

Research Collection School Of Economics

R&D has grown robustly, yet aggregate productivity growth has stagnated. Is this because “ideas are getting harder to find”? Using microdata from the US Census Bureau this paper estimates R&D effectiveness in the manufacturing sector from 1976 to 2018. We find that the marginal effect of R&D on output and the gross marginal returns to R&D have risen sharply. But rivals’ R&D has also gotten more effective, raising expected obsolescence. But firm productivity growth rises with growth in the R&D stock. Higher obsolescence slows the accumulation of R&D capital, reducing the contribution to productivity growth and shortening innovation lives.

The Aggregate Welfare And Trade Implications Of Contracting Frictions In Global Sourcing, Davin Chor, Lin Ma

Research Collection School Of Economics

How much do contracting frictions between global firms and their suppliers impact country welfare and trade? We answer this by developing a model of global sourcing under partial contractibility, where firm-supplier relationships are exposed to a bilateral holdup problem. Sourcing decisions aggregate into a gravity equation for trade flows by organizational mode (intrafirm vs. arm’s length), which we take to structural estimation. We can then evaluate welfare changes with an extended Arkolakis, Costinot and Rodriguez-Clare (2012) formula that incorporates these contracting frictions. Our counterfactual analysis reveals a sizeable average country welfare gain of 9.2% from eliminating contracting frictions in global …

High Frequency Factor Analysis With Partially Observable Factors, Dachuan Chen, Wenqi Lu, Siyu Xie

Research Collection School Of Economics

This paper considers a novel factor structure – Partially Observable Factor Model – where both observable factors and latent factors exist in the model simultaneously. Such factor structure can make sure both interpretability and goodness-of-fit at the same time. Necessary estimation methodologies for this partially observable factor model are developed in this paper for the high frequency data. The proposed estimation methodology is robust to jumps, microstructure noise and asynchronous observation times simultaneously.When the observable factors are exogenous, we provide the estimation theory for the integrated eigenvalues of the residual covariance matrix, which including the bias-corrected estimator, central limit theorem …

Hyflex Delivery For Year-Long 10 Credit Evening Module, Cathal Curran

Case studies: Digital Education

I trialled the HyFlex delivery for the LAW4021 Jurisprudence module over the full academic year. This module is a 10-credit module and is particularly relevant for those part-time LLB (TU115) students who have progressed from the undergrad BA Ord (TU112) programme, given it is a ‘core’ module. Those who may want to progress to train at the King’s Inns must take Jurisprudence, so the uptake on the module tends to be strong year-upon-year. For this reason, I thought it would be an apt choice to trial HyFlex as there is usually a critical mass in the face-to-face context, and I …

There are many new stories to embrace but also quiet distances between us that we must bridge.

In a National Day op-ed published in The Straits Times, SMU President Professor Lily Kong reflects on what ‘home’ means as Singapore marks its 60th year of independence — and how that meaning continues to evolve across generations. Prompted by a walk through a familiar playground now transformed, Prof Kong considers how Singapore’s changing physical and social landscape mirrors shifts in national identity. While progress and policy evolution signal a society in transition, she also notes the emergence of quieter divides – between …

Diaspora By Another Name: The Making Of Refugees In Cold War China, Jiaqi M. Liu, Clare Xiaoqian Wan

Research Collection School of Social Sciences

By examining China’s refugee policies from 1949 to 1982, this article demonstrates how the Chinese state redefined “return” and “refugee” to serve shifting political objectives. While China is often perceived as a source, rather than a host, of asylum seekers, it hosted over 320,000 displaced migrants—primarily ethnic Chinese from Southeast Asia—during the Cold War. Through a systematic discourse analysis of 382 People’s Daily articles, we identify four state narratives—diaspora, diplomatic tool, ideological sanctuary, and legal duty—that structured how China labeled displaced migrants, interpreted their sentiments, and determined their settlement. These models evolved dynamically: from the 1950s to the late 1970s, …

Governing Migration, Producing Skills: Emigration And Education In The Philippines, Yasmin Y. Ortiga, Roderick. Galam

Research Collection School of Social Sciences

This article examines skill as an integral yet understudied aspect of emigration governance. To date, migration studies have mainly focused on how the demand for migrant skills drive people's movements across borders, shaping the conditions for entry into popular destinations in the West. In contrast, less is known as to how skills also shape the way governments manage emigration, pushing would-be migrants to acquire certain capacities well before they leave their countries of origin. Drawing from the case of the Philippines, this article discusses how state agencies have used skills training to dominate specific markets for migrant professionals and demand …

Stockpiling, Forecasting And Protecting Skills: Skilling As Technique Of Preparedness In Times Of Crises, Rebecca Ye, Yasmin Y. Ortiga

Research Collection School of Social Sciences

In this comparative and situational analysis, we examine how nation-states use skilling as a technique of preparedness during crisis moments. By analysing two strategically selected country cases, Singapore and Sweden, during a critical phase of a global pandemic, we identify three techniques: stockpiling, forecasting, and protecting skills, and how these were enacted as a means to perform preparedness. Stockpiling skills was observed to take place as a rapid response; forecasting skills was a technique enacted with a view on the longer-term horizon and protecting skills was mobilised as a short-term future technique, where boundaries were assembled around skilling. While there …

Language Brokering Conditions The Indirect Association Between Mexican‐Origin Adolescents' Academic Discrimination And Educational Expectations, Su Yeong Kim, Yayu Du, Chantal Alvarado, Wei Xiang Sim, Wen Wen, Tianlu Zhang, Jingyi Shen

Research Collection School of Social Sciences

Mexican-origin adolescents, a significant portion of the US Latino population, often experience a decline in educational expectations from early to late adolescence. Contextual factors such as academic discrimination and language brokering for parents may contribute to this decline. This study investigates the indirect effect of academic discrimination experienced in middle school on educational expectations in young adulthood through high school grades and engagement, and the moderating role of language brokering experiences in these relations. Data were collected from 604 Mexican-origin adolescents across four waves from 2012 to 2023. Academic discrimination experiences in middle school were negatively associated with school grades …

Religious Beliefs, Cooperation, And Evolutionary Mechanisms, Nicole Fellice Ko, Norman P. Li

Research Collection School of Social Sciences

Religion is an organized system of spiritual beliefs, practices, and rituals that often involve a sense of the divine (Schilbrack, 2022). An evolutionary mechanism is an evolved set of traits that interpret environmental inputs and generate behavioral responses that enhance survival or reproductive success (Li et al., 2018). Cooperation refers to the act of individuals or groups working together to achieve a shared goal or mutual benefit (Alós-Ferrer & Garagnani, 2020).

Negotiating Racial Subjection: Analysing Black And Indigenous Resistance From Within Colonial Orders, Owen R. Brown, Arturo Chang

Political Science Faculty Publications and Presentations

This article addresses recent work on empire and colonisation which calls for a reappraisal of how agency and resistance manifests among groups responding to structural marginalisation. We argue that approaching these questions from within the colonial order reveals important idiosyncrasies regarding how groups understood resistance, agency, and popular organising as possible responses that emerged from within imperial landscapes. Using the example of race as a central regulatory category and practice of colonial power, we analyse two cases which we suggest benefit from an account of agency and resistance within colonial order: the Black Loyalists in English America and the Indigenous …

One-Sided Limited Commitment And Aggregate Risk, Yoshiki Ando, Dirk Krueger, Harald Uhlig

Research Collection School Of Economics

In this paper we study the neoclassical growth model with idiosyncratic income risk and aggregate risk in which risk sharing is endogenously constrained by one sided limited commitment. Households can trade a full set of contingent claims that pay off depending on both idiosyncratic and aggregate risk, but limited commitment rules out that households sell these assets short. The model results, under suitable restrictions of the parameters of the model, in partial consumption insurance in equilibrium. With log-utility and idiosyncratic income shocks taking two values one of which is zero (e.g., employment and unemployment) we show that the equilibrium can …

Going Gray Too Early? Effects Of Color On Facial Identification, Roman M. Pardo

Masters Theses (Archived)

This study investigated a possible bias in face-matching and ID-screening decision making- color incongruity (i.e., one face image presented in color and one in grayscale). Expanding on previous research, the 2x2 mixed methods experiment incorporated eye tracking measures (i.e., fixations). Participants N= 25 were randomly assigned to compare color or grayscale IDs (between groups comparison) to a 10 s color video of a person moving their head side to side. The task consisted of 2 practice and 48 face-matching trials with medium prevalence (MP, 24 match, 24 mismatch) presented as one of four pseudo-random and counterbalanced orders. Signal detection …

Hydrogen Fuel Cell Application For Port Drayage Truck: Integrated Transportation And Energy Modeling, Shams Tanvir, Emu Ghosh

Mineta Transportation Institute

This report investigates the viability of hydrogen Fuel Cell Electric Vehicles (FCEVs) for port drayage applications, focusing on both energy modeling and economic feasibility. Port drayage—trucking operations that move goods a short distance to and from ports—is a key part of freight logistics and the critical movement of goods in American communities. This project developed a microscopic energy consumption model using second-by-second activity data from 38 Class 8 diesel drayage trucks operating in Southern California. The model emulated FCEV operations and determined an average hydrogen fuel consumption of 0.15 kg/mile across 749 trips. This data informed a levelized cost of …

Student Imaginaries: The Role Of Universities In Addressing The Polycrisis, Susana Maria Ruiz Sors

Theses and Dissertations

This thesis explores graduate student perceptions from the Public Affairs and Security Studies (PASS) program at the University of Texas Rio Grande Valley (UTRGV) regarding the role of universities in addressing interconnected environmental, economic, political, and social challenges, described here as a “polycrisis” (Lawrence et al., 2024). Using a mixed-methods approach, the study surveyed 42 students through Likert-scale questions and open-ended prompts. Results show students view economic inequality, political instability, and threats to democracy as the most pressing societal issues. While environmental issues were seen as important, they ranked lower in urgency. Students expect universities to address these challenges through …

Who Dominates The Coalition? Frame Salience And Public Support For Policy–Democracy Protest Coalitions Under Authoritarian Rule, Mai T. Truong

Political Science Faculty Research and Publications

How does the public support a coalition in which pro-democracy advocates and policy-based protesters join forces in street protests? When policy-based and pro-democracy groups protest together, they create a collective action frame that includes a policy component and a democracy component. In this article, I develop the frame salience theory, arguing that support for a policy–democracy protest coalition depends on which component of the joint frame is perceived to be more dominant. I argue that in authoritarian regimes, the policy component typically dominates the coalition because it is more accessible and available to the public. This perception shifts public support …

Wild Hogs In The Water: Contested Infrastructural Ecologies Of Reservoir Storage In Texas, Sayd Randle

Research Collection College of Integrative Studies

Reservoirs are developed to store water in reserve for future use. But once built, reservoir sites inevitably hold more than just water, often serving as a key habitat for a range of species. This paper examines how one such animal has transformed water storage facilities and nearby landscapes into contested ground in urbanising areas of Texas, USA. Living around the reservoirs, feral hogs complicate the process of urbanisation by degrading the stockpiled water and infrastructure at the storage sites themselves and by damaging private property throughout the surrounding landscape. Tracking local efforts to manage the hogs, the case study illustrates …

This Symposium sketches the contours of a framework we term political ecologies of storage. In doing so, we treat storage as both a potent imaginary and a concrete …
