“Megadeal” Subsidies, Local Spillovers And Corporate Innovation, Yoojin Lee, Shaphan Ng, Aruhn Venkat

Research Collection School Of Accountancy

We examine whether the largest place-based, firm-specific corporate subsidies (“Megadeals”) awarded by state and local governments affect local firms’ innovation. First, we document that 1) subsidy firms innovate in the subsidized county and 2) subsidy firms bring inventors from other counties into the subsidized county, consistent with subsidy firms generating new knowledge locally. In our main test, we use a stacked cohort design with stringent fixed effects to document that local firms increase patenting following a Megadeal. Cross-sectionally, effects are increasing 1) in subsidy firm innovativeness, 2) in the technological closeness of subsidy firms and local firms, 3) when subsidy …

Using Satellite-Observed Geospatial Inundation Data To Identify The Impacts Of Floods On Firm-Level Performance: The Case Of China During 2000–2009, Pao-Li Chang, Fan Zheng

Research Collection School Of Economics

This paper compiles high-resolution geospatial inundation areas of China for the period 2000–2009 based on satellite imagery repositories filtered by the Global Flood Database (GFD). In parallel, we geocode a comprehensive firm-level dataset of China and combine these two sets of geospatial data to identify the set of inundated firms in each year of flood events, as well as the distances of all non-inundated firms from the inundated areas. Given the high-resolution inundation data, we adopt a generalized dynamic-panel specification to estimate dynamic and spatial spillover effects of floods on firm-level production activities (including outputs, capital and labor inputs, and …

Financial Valuation Of Retirement Village Via Stochastic Modelling Of Disability Prevalence Rates, Jackie Li, Mingke Wang, Jia Liu, Jessica Wai Yin Leung

Research Collection School Of Economics

Global mortality rates continue to decline, and life expectancy continues its upward trend. Besides mortality levels, policymakers and providers of financial and health services would also be interested in disability prevalence and its potential future trajectories. The length of time in good health versus the duration with major disabilities or long-term illnesses has significant financial implications for both individuals and society. In this paper, we develop Bayesian common factor models to analyse Australian age- and sex-specific disability prevalence rates. In particular, there are one or more common factors shared by both sexes, as well as specific factors for each sex. …

Removed: When Taxi Drivers Meet Dynamic Pricing: A Lesson From Singapore's Justgrab Program, Shih-Fen Cheng, Wen-Tai Hsu, Jing Li

Research Collection School Of Economics

This paper studies how dynamic pricing influences taxi drivers’ behaviors using a unique event, the inception of the JustGrab program in Singapore in 2017, which introduces dynamic pricing to some, but not all, taxi drivers. This is the first time in history that traditional taxi drivers have access to dynamic pricing. Using data covering the universe of taxi trips before and after the inception of JustGrab, we find that there is spatial reallocation that directs more taxi drivers to the previously less-served areas, that there is also a temporal reallocation that directs more taxi drivers to rush hours, as well …

Product Technology Adoption And Aggregate Innovation, Qiugu He, Xuan Luo, Fan Zheng

Research Collection School Of Economics

We document that a firm's research and development (R&D) expenditure depends on its product diversity. Combining with the fact that Chinese manufacturers often enter new product markets via technology adoption, we develop a quantitative framework of innovation and technology adoption, allowing firms to expand their product scopes. Firms adopt technologies across multiple fields to expand their knowledge base, which in turn serves as an input for subsequent innovation or adoption. Counterfactual analysis from the 2000s reveals that two-thirds of knowledge privately held by all firms is generated through adoption, accounting for one-third of aggregate innovation.

How Industrial Clusters Affect Technological Innovation: Evidence From Vanyang Small & Micro Industrial Park, Jianming Wu

Dissertations and Theses Collection (Open Access)

This study focuses on the mechanism through which industrial clusters enhance technological innovation among micro and small enterprises. Using the VanYang Micro-Enterprise Park in Zhejiang Province as a representative case, the research integrates perspectives from industrial cluster theory, innovation theory, and spatial economics to explore how clustered environments influence enterprise innovation performance through resource integration, knowledge spillovers, and organizational collaboration. Departing from traditional static comparative methods, this study adopts an event study approach to dynamically capture the impact trajectory and temporal structure of enterprise innovation performance, with "entry into the park" serving as the key event.

Based on panel data …

Digital Twin Dynamics: Employee’S Willingness To Adopt Ai Digital-Twin In A Craftsmanship Environment, Seow Hoon Tee

Dissertations and Theses Collection (Open Access)

Singapore’s manufacturing sector, contributing 22% to the nation’s GDP, is undergoing a strategic transformation under the Manufacturing 2030 vision, which aims to increase sector value by 50%. However, a critical challenge emerges in the widening age gap among craftsmen, particularly between 30 and 50 years old, misaligning with succession planning efforts. As senior craftsmen approach retirement, the urgency to transfer specialized expertise significantly increases. In response, initiatives such as the National AI Strategy (NAIS) 2.0 and Industry 5.0 efforts by the Singapore Manufacturing Federation (SMF) and Advanced Remanufacturing and Technology Centre (ARTC) emphasize AI-driven solutions to enhance knowledge retention and …

How Do Insurance Companies Manage Reserves? Evidence From Reserve Errors Across Lines Of Business And Accident Years, Jing Rong Goh, Shinichi Kamiya, Pingyi Lou

Research Collection School Of Economics

We study the question of how insurance companies manage reserves. Specifically, we investigate how managerial incentives affect insurers’ reserving practice across lines of business (LOBs) and accident years (AYs). Because the tax discount factor the tax authority assigns varies across LOBs and AYs, insurers with stronger tax-saving incentives will be inclined to manage reserves across both LOBs and AYs. In contrast, since the Risk Based Capital (RBC) regime specifies different industry worst-case factors across LOBs, insurers with stronger incentives to increase their RBC ratio will be inclined to manage reserves across LOBs. Regarding income-smoothing incentives, only the overall level (and …

The Scale Question As An Urban Question: The Making Of Homo Urbanicus Amid State Entrepreneurialism, Yong Zhang

Research Collection College of Integrative Studies

This research bridges two influential strands of literature on urban China—state entrepreneurialism and homo urbanicus (城市人). By revisiting how China’s post-reform urban transformation has unfolded and connecting it to current development strategies, this research provides a fresh perspective on the country’s urbanization processes and their implications for future governance. The analysis proposes an alternative periodization of three phases: anti-migration urbanism, anti-settlement urbanism, and anti-civitas urbanism. Beyond understanding urbanization as a crisis-driven, state-rescaling phenomenon pivoting around the blending of state and market forces, this research repositions the concept of homo urbanicus, or the urban citizen, as central to understanding the urban …

Regulatory Protection And The Role Of International Cooperation, Yuan Mei

Research Collection School Of Economics

I develop a general equilibrium framework to analyze the welfare consequences of product regulations and their international harmonization. In my model, raising product standards reduces a negative consumption externality, but also increases the marginal and fixed costs of production. When product standards are set noncooperatively, the effects of standards on other countries' wages and number of firms are not internalized, giving rise to an international inefficiency. The World Trade Organization's nondiscrimination principle of national treatment only partly addresses this inefficiency. Welfare losses from abandoning national treatment average 2.8%, whereas the maximum welfare gains from efficient cooperation average 11.8%.

Obfuscation And Rational Inattention, Aljoscha Janssen, Johannes Kasinger

Research Collection School Of Economics

We study the behavior of duopolistic firms that can obfuscate their prices before competing on price. Obfuscation affects the rational inattentive consumers' optimal information strategy, which determines the probabilistic demand. Our model advances related models by allowing consumers to update their unrestricted prior beliefs with an informative signal of any form. We show that the game may result in an obfuscation equilibrium with high prices or a transparency equilibrium with low prices and no obfuscation, providing an argument for market regulation. Obfuscation equilibria cease to exist for low information costs and if one firm seems a priori considerably more attractive.

The Distributional Impacts Of Transportation Networks In China, Lin Ma, Yang Tang

Research Collection School Of Economics

We document that the quality of roads and railroads vary substantially over time and space in China, and neglecting these variations biases the distributional impacts of transportation networks. To account for quality differences, we construct a new panel dataset and approximate quality using the design speed of roads and railroads that varies by vintage, class, and terrain at the pixel level. We then build a dynamic spatial general equilibrium model for multiple modes, transportation routes, and forward-looking migration decisions. Our findings demonstrate that disregarding quality differences leads to a median bias of approximately 31% in estimating real wage growth rates …

How Tiktok “Locks In” Its Users With Reference To What Happened In The Homeland Version Douyin Application, Yang Yang, Li Zi'ang, Zhigen Zhao, Sabrina (Zi Tong) Peng, Liyu Dou, Changyu Li, Yinqi Wang

Research Collection School Of Economics

In October 2022, Douyin, the homeland version of TikTok, introduced a new rule requiring all its users to promote only Douyin-approved products during their live-streaming events and in their non-live short-videos. This requirement essentially restricts its users to monetize their content strictly through Douyin-approved products, as promoting products has become the most important source of income for Douyin users. This requirement essentially creates a lock-in effect.

Financial Crisis And Female Entrepreneurship: Evidence From South Korea, Jungho Lee, Sunha Myong

Research Collection School Of Economics

We document a drastic increase in female-owned manufacturing firms in South Korea after the 1997 financial crisis. During the crisis, a major banking sector reform was conducted, and many underperforming bank branches were forced to close down. Using a geographical variation of bank branch closures during the reform, we show that the banking sector reform resulted in a rise in female entrepreneurship. We present evidence that male-owned firms were preferred by the closeddown bank branches, despite female-owned firms exhibiting lower risks and higher returns. The banking sector reform, although not explicitly aimed at addressing gender disparities, substantially benefited female entrepreneurs …

The Distributional Impacts Of Transportation Networks In China, Lin Ma, Tang Yang

Research Collection School Of Economics

This paper evaluates the distributional impacts of transportation networks in China. We show that the quality of roads and railroads vary substantially over time and space, and ignoring these variations biases the estimates of travel time. To account for quality differences, we construct a new panel dataset and approximate quality using the design speed of roads and railroads that varies by vintage, class, and terrain at the pixel level. We then build a dynamic spatial general equilibrium model that allows for multiple modes and routes of transportation and forward-looking migration decision. We find aggregate welfare gain and less spatial income …

Retail Pharmacies And Drug Diversion During The Opioid Epidemic, Aljoscha Janssen, Xuan Zhang

Research Collection School Of Economics

This study investigates the role of retail pharmacy ownership in the opioid epidemic. Using data of prescription opioid orders, we show that compared with chain pharmacies, independent pharmacies dispense 39.1% more opioids and 60.5% more OxyContin. After an independent pharmacy becomes a chain pharmacy, opioid dispensing decreases. Using the OxyContin reformulation, which reduced non-medical demand but not the legitimate medical demand, we show that at least a third of the difference in the amount of OxyContin dispensed can be attributed to non-medical demand. We show that differences in competitive pressure and whether pharmacists own the pharmacy drive our estimates.

R&D Subsidies In Permissive And Restrictive Environment: Evidence From Korea, Yumi Koh, Gea M. Lee

Research Collection School Of Economics

This paper investigates the extent to which a regulatory environment for R&D subsidies shapes the magnitude and direction of R&D subsidies set by a government and consequent innovation paths. When the WTO adopted a permissive regulatory environment, we find that the Korean government increased R&D subsidies significantly (89.21%) and selectively so for firms and industries with higher returns. Recipient firms conducted less basic research and more development research. Improvements in innovations were mostly incremental and minor. However, such changes did not persist once the WTO switched to a restrictive regulatory environment. Our findings show that the regulatory environment imposed by …

Price Dynamics Of Swedish Pharmaceuticals, Aljoscha Janssen

Research Collection School Of Economics

This paper investigates price patterns of off-patent pharmaceuticals in Sweden. I show that price dynamics are dependent on the number of competitors in the market. The price patterns follow predictions from a model of dynamic price competition in which the demand for pharmaceuticals incorporates the known biases of consumers: habit persistence and brand preferences. Using the regulated market of Swedish pharmaceuticals, I show that price dynamics may help in identifying possible tacit collusion by manufacturers in markets where consumers experience behavioral frictions.

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 …

Attenuation Of Agglomeration Economies: Evidence From The Universe Of Chinese Manufacturing Firms, Li Jing, Liyao Li, Shimeng Liu

Research Collection School Of Economics

This paper quantifies industry-specific spatial attenuation of agglomeration economies by taking advantage of unique geocoded administrative data on the universe of Chinese manufacturing firms. The estimates of industry-level attenuation speed further allow us to systematically assess the goodness of fit of various spatial decay functional forms and to evaluate the micro-foundations that govern the decay patterns across industries. We obtain three main findings. First, agglomeration spillovers attenuate by about 90 percent on average from 0-1 km to 1-5 km in China, with large heterogeneity in the extent of attenuation ranging from 73 percent to 116 percent across industries. Second, the …

Government Support For Smes In Response To Covid-19: Theoretical Model Using Wang Transform, Shaun Shuxun Wang, Jing Rong Goh, Didier Sornette, He Wang, Esther Yang

Research Collection School Of Economics

Purpose: Many governments are taking measures in support of small and medium-sized enterprises (SMEs) to mitigate the economic impact of the COVID-19 outbreak. This paper presents a theoretical model for evaluating various government measures, including insurance for bank loans, interest rate subsidy, bridge loans and relief of tax burdens. Design/methodology/approach: This paper distinguishes a firm's intrinsic value and book value, where a firm can lose its intrinsic value when it encounters cash-flow crunch. Wang transform is applied to (1) calculating the appropriate level of interest rate subsidy payable to incentivize banks to issue more loans to SMEs and to extend …

Learning By Supplying And Competition Threat, Yi-Fan Chen, Alireza Naghavi, Shin-Kun Peng

Research Collection School Of Economics

This study proposes a model of learning by supplying in an international outsourcing framework, where the supplier of a relationship-specific input can reverse engineer and become a competitor to its partner in the final goods market. Transmitting knowledge to a more capable supplier therefore creates competitive threat despite the benefits it brings within an outsourcing relationship. In particular, in markets with less differentiated products and for standard inputs that require less knowledge to be shared, choosing an intermediate capability level supplier prompts a strategic expansion of output to deter supplier entry in the final goods market, resulting in higher profits …

Public Health Insurance And Pharmaceutical Innovation: Evidence From China, Xuan Zhang, Huihua Nie

Research Collection School Of Economics

Developing countries are characterized by low levels of pharmaceutical innovation. A likely reason is their small market size, which is not because of the population size but because of low levels of income and lack of health insurance coverage. This study exploits a natural experiment from the implementation of a public health insurance program for rural residents in China (New Cooperative Medical Scheme [NCMS]) to examine whether the pharmaceutical industry increases innovation regarding diseases covered by the NCMS that are prevalent in rural areas. We examine the 1993–2009 patent data to gauge pharmaceutical innovation in China. Diseases with a 10% …

Firm Productivity And The Variety Of Inputs And Outputs: Evidence From Chinese Trade Data, Ken Onishi, Jianhuan Xu, Guang Yang

Research Collection School Of Economics

This paper studies how the trade liberalization in China changes the firm productivity. We develop a framework to estimate revenue productivity (TFPR) and real productivity (TFPQ) with multi-product firms. We find that the aggregate TFPR increases 30\% from 2002-2007 and TFPQ increases 22\%, suggesting that the observed TFPR increase is mainly driven by real productivity change rather than the markup change. We further decompose the change of productivity into three channels: (1) access to foreign inputs; (2) technology upgrade; (3) resource re-allocation within the firm. We find the most significant channel is the last one, which explains half of the …

Density Of Demand And The Consumer Benefit From Uber, Matthew H. Shapiro

Research Collection School Of Economics

Uber has attracted the attention of economists and policy makers for its innovations in the taxicab market and its potential for significant consumer welfare gains. The size of this gain depends in part on whether these innovations permit transactions previously costly or infeasible. Using New York City — the largest taxi market in the country — as its context, this paper estimates the level of any technological advantage Uber has over hail taxis in matching to consumers. I combine publicly available transportation data with data scraped from Uber and traffic cameras to estimate a model of the demand for transportation …

The Convergence Of Water, Electricity And Gas Industries: Implications For Ppp Design And Regulation, Sock Yong Phang

Research Collection School Of Economics

In several countries that have privatised their utilities, power and water are separate industries regulated by sector-specific regulators. In a parallel development, desalination has become an important source of water supply in countries where there is a shortage of cheap and clean freshwater. Where the energy source is gas, the use of gas-fired power plants to supply electricity for desalination links the water, electricity and gas industries. We use the case of the financial collapse of an integrated water and power project to illustrate the problems that can arise from such convergence, and to draw lessons for firms, Public-Private Partnerships …

The Optimal Degree Of Reciprocity In Tariff Reduction, Pao-Li Chang

Research Collection School Of Economics

This paper characterizes the optimal reciprocal trade policy in the environment of Melitz (2003) with firm productivity heterogeneity. With all the conflicting effects of import tariffs on welfare considered, the optimal degree of reciprocity in multilateral tariff reduction is shown to be free trade.

The Optimal Degree Of Reciprocity In Tariff Reduction, Pao-Li Chang

Research Collection School Of Economics

This paper characterizes the optimal reciprocal trade policy in the environment of Melitz (2003) with firm productivity heterogeneity. In particular, without making parametric assumptions on firm productivity distribution, this paper derives the optimal degree of reciprocal tariff reductions that maximize the world welfare. A reciprocal import subsidy raises the industry productivity, lowering aggregate price; a reciprocal import tariff helps correct the markup distortion, increasing nominal income. With all the conflicting effects of import tariffs on welfare considered, the optimal degree of reciprocity in multilateral tariff reduction is shown to be free trade.

Individuals Responses To Economic Cycles: Organizational Relevance And A Multilevel Theoretical Integration, Nina Sirola

Research Collection Lee Kong Chian School Of Business

The state of the economy represents a concern for individuals and shapes their behavior in profound ways. The current review of studies on how individuals respond to economic cycles reveals that organizational relevance of such responses has often not been considered, and the literature is characterized by a variety of seemingly disconnected explanations for how and why individuals respond to the perceived state of the economy. I develop a theoretical framework that systematizes the literature and accounts for the seemingly disparate findings, highlighting the underlying functionality of such responses for individuals. I then integrate the literature on individual responses to …

Estimating The Benefits And Costs Of Forming Business Partnerships, Jungho Lee

Research Collection School Of Economics

I estimate a matching model of business‐partnership formation to quantify the relative importance of productivity gains, financing gains, and the coordination failure of effort provision (moral hazard) among partners. Productivity gains account for 61% of the gain from the observed partnerships. For partners in the first quartile of the wealth distribution, however, financing accounts for 93% of the gain. The cost of moral hazard corresponds to 42% of the entire gain from partnerships. A loan policy specifically targeting partnerships is less effective in improving welfare than a conventional loan policy that provides loans to individual entrepreneurs.
