Crisis, Credit Risk, And Productivity: Lessons From The Vietnamese Banking Sector During Covid-19, Van Nguyen, Phuong Thanh Le, Reza Kiani Mavi, Amir Arjomandi

Research outputs 2022 to 2026

This study investigates how an unprecedented systemic shock, the COVID-19 pandemic, reshaped bank productivity and intermediation efficiency in Vietnam, one of the fastest-growing emerging economies. We develop a novel risk-adjusted total factor productivity (TFP) measure based on the by-production Luenberger–Hicks–Moorsteen (LHM) indicator, which incorporates non-performing loans as undesirable outputs to better capture credit-risk dynamics. Using a balanced panel covering both the pre-pandemic and pandemic periods (2016–2022), our results show that Vietnamese banks experienced a general decline in productivity before and during COVID-19, driven largely by reductions in technical and scale efficiency. However, foreign and state-owned banks recorded stronger technological progress …

Algorithm Envelopment In Platform Markets, Liang Chen, Zhou Zhou, Lester Chan

Research Collection Lee Kong Chian School Of Business

The theory of platform envelopment rests on network effects as the key mechanism for value creation, which nonetheless receives mixed support for its efficacy in determining competitive outcomes. We argue that the value of network effects depends on matching quality, which is a function of platform-specific algorithm technology and market-level data-driven learning. In formalizing these conceptualizations, we analyze a model that demonstrates how an entrant with a superior algorithm technology may outcompete an incumbent possessing a user base advantage, a strategy we call “algorithm envelopment.” By considering specific characteristics of data-driven learning, our analysis leads to propositions regarding the entry …

Fraudulent Transfers And Sovereign Immunity, David G. Carlson

Articles

The article argues that the Supreme Court's decision in United States v. Miller was wrongly decided because it failed to recognize that sovereign immunity is waivable and does not protect the government when it trespasses upon preexisting property rights. The analysis contends that fraudulent transfer claims are quasi in rem actions, meaning the sovereign is subject to the incidental procedures of bankruptcy once enmeshed in such proceedings.

How The U.S. Constitution Shapes International Tax Law: Instrument Choice In Tax Agreements, Noam Noked, Young Ran (Christine) Kim, Reuven S. Avi-Yonah

Articles

The U.S. Constitution’s Treaty Clause, which requires Senate approval by a two-thirds vote for treaties, has significantly influenced the development of international tax law. This Article examines the implications of Senate supermajority requirements on bilateral and multilateral tax treaties and agreements, alternative instruments, relevant international tax standards, and global tax governance.

Historically, tax treaties have been approved exclusively as Article II treaties requiring Senate approval. The difficulty of entering into treaties with the United States has influenced the instrument choice and design of U.S. and international tax standards. To address this challenge, several U.S. and international tax reforms have employed …

Who Decides Who Gets Deported?, Peter L. Markowitz, Mauricio Noroña

Articles

As President Donald Trump began his second term in office, he promised to implement the largest mass deportation program in the history of the United States. With unprecedented increases in immigration enforcement funding secured by his Administration, the infrastructure to carry out these plans is being rapidly expanded. While there are good reasons to be skeptical of President Trump’s grandiose promises, and even better reasons to be concerned about the devastation flowing from such a program, one thing is certain: over the last three decades, we have seen a dramatic expansion of the categories of immigrants who can be subject …

Standard Textualism, James A. Macleod

Articles

For as long as legal scholars have been writing about the rules-versus-standards distinction, textualism has been understood to produce characteristically rule-like law. This Article argues for the opposite view. Far from generating the “law of rules” that Scalia famously envisioned, the rule of modern textualism produces a law of standards—much more so than anybody, proponent of textualism or critic, appears to have recognized.

Two aspects of today’s textualism produce this result. The first is its emphasis on ordinary language and communication. Modern textualism typically produces standards because ordinary language and communication are typically standard-like. The second is modern textualism’s drive …

Trophy Assets, Aneil Kovvali

Articles

Rich people like to own things that make them look cool. When the thing in question is a car, house, or boat, the implications are limited. But sometimes very rich people own assets that are more important. Within media, Elon Musk acquired Twitter, Jeff Bezos ac-quired the Washington Post, and Patrick Soon-Shiong acquired the Los Angeles Times. There has also been a craze for aerospace: Musk with Space X, Bezos with Blue Origin, Richard Branson with Virgin Galactic, and going back further, Howard Hughes with Hughes Aircraft Company. It is often difficult to understand the behavior in purely finan-cial terms, …

The Enduring Case For Bankruptcy Exceptionalism, Jared Mayer

Articles

Nearly fifty years after Congress enacted the Bankruptcy Code, a debate has emerged over the existence and desirability of “bankruptcy exceptionalism”: the idea that bankruptcy law should utilize “flexibility, creativity, and pragmatism over technicalities of process and form” to “prioritize fidelity” to “the purposes for which it was created.”  This question is especially salient in the world of corporate reorganizations, where distressed companies and their investors retain counsel precisely for the purpose of hammering out deals in complex commercial settings. In this Essay, I defend bankruptcy exceptionalism in corporate reorganizations.  I show that bankruptcy exceptionalism is a necessary and desirable …

The Effects Of Financing Green And Brown Sectors: What Do Theories And Evidence Say?, Hao Liang, Maria Teresa Punzi

Research Collection Lee Kong Chian School Of Business

This paper critically examines the economic and welfare implications of financing green and brown sectors. Drawing on a comprehensive review of recent theoretical and empirical literature, we highlight that while conventional green finance—allocating capital toward environmentally friendly (“green”) sectors and away from carbon-intensive (“brown”) sectors—can promote decarbonization, it may also produce unintended externalities. In particular, it can inadvertently incentivize higher emissions from brown firms and contribute to economic disruption. Using a dynamic stochastic general equilibrium (DSGE) model, we demonstrate that lowering the cost of capital for green sectors leads to only modest reductions in emissions, whereas raising it for brown …

Elli’S Liquid Flow In A Wavy Channel With Slip Effect, Wall Properties, And Heat Transfer, P. Devaki, Yatin Sood

Mansoura Engineering Journal

The dual behavior of Elli’s fluid motivated us to work on it. The fluid behaves as both Newtonian/ non-Newtonian based on the low and high shear rates, respectively. The paper focused on the flow of Ellis fluid in a peristaltic channel with wall properties and heat transfer. The channel is symmetric in nature, and slip conditions are considered near the elastic walls. The governing equations of the flow are solved analytically using suitable boundary conditions, which yield velocity and temperature functions. The novelty of the paper is to analyze the nature of Newtonian/non-Newtonian fluids under the same conditions so that …

Underwater Image Identification Using Fuzzy Soft Planar Graph, Bhuvaneswari Natarajan Jayakar, Karthick Palanisamy

Mansoura Engineering Journal

High-attribute underwater image segmentation is fundamental to autonomous marine exploration, biodiversity monitoring, and subsea infrastructure inspection. However, underwater environments are inherently stochastic, exhibiting severe light attenuation, chromatic distortion, scattering effects, and noise, all of which significantly degrade image quality and challenge conventional computer vision techniques. Hence, Fuzzy logic which handles uncertainty and imprecision in data and Soft sets which manage parameterized information, are widely applied to underwater image analysis. Fuzzy Soft Planar Graphs (FSPGs) constitute a mathematical framework that integrates fuzzy set theory, soft set theory and planar graph structures for preserving spatial topology. The proposed methodology adopts a hybrid …
