Regulatory Protection And The Role Of International Cooperation, Yuan Mei Nov 2023

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 Nov 2023

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, Tang Yang May 2023

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 inequality led …


R&D Subsidies In Permissive And Restrictive Environment: Evidence From Korea, Yumi Koh, Gea M. Lee Jan 2023

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 …


Retail Pharmacies And Drug Diversion During The Opioid Epidemic, Aljoscha Janssen, Xuan Zhang Jan 2023

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.


Intra-Firm Hierarchies And Gender Gaps, Nicolo Dalvit, Aseem Patel, Joanne Tan Aug 2022

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 Jul 2022

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 Jul 2021

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 …


Public Health Insurance And Pharmaceutical Innovation: Evidence From China, Xuan Zhang, Huihua Nie Jan 2021

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% …


Density Of Demand And The Consumer Benefit From Uber, Matthew H. Shapiro Dec 2020

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 Dec 2020

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 …


Firm Productivity And The Variety Of Inputs And Outputs: Evidence From Chinese Trade Data, Ken Onishi, Jianhuan Xu, Guang Yang Dec 2020

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 …


The Optimal Degree Of Reciprocity In Tariff Reduction, Pao-Li Chang Sep 2020

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 Sep 2020

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 Jul 2020

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 Jun 2020

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.


Foreign Direct Investment And Industrial Agglomeration: Evidence From China, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu Apr 2020

Foreign Direct Investment And Industrial Agglomeration: Evidence From China, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu

Research Collection School Of Economics

This paper studies the effect of foreign direct investment (FDI) on industrial ag-glomeration. Using the differential effects of FDI deregulation in 2002 in China on different industries, we find that FDI actually affects industrial agglomeration neg-atively. As FDI brings technological spillovers and various agglomeration benefits, other forces must be at work to drive our empirical finding. We propose a simple theory that FDI may discourage industrial agglomeration due to fiercer competition pressure. We find various evidence on this competition mechanism. We also examine an alternative theory based on spatial political competition, but find no evidence sup-porting it. On industrial growth, …


Why Do Businesses Grow Faster In Urban Areas Than In Rural Areas?, Lee, Jungho, Jianhuan Xu Mar 2020

Why Do Businesses Grow Faster In Urban Areas Than In Rural Areas?, Lee, Jungho, Jianhuan Xu

Research Collection School Of Economics

We document that growth of business earnings is mostly observed among young firmsin metro areas. Three explanations are considered: metro areas attract more-productiveentrepreneurs, and reaching the optimal size takes time due to borrowing constraints;metro areas provide better learning opportunities; and high operating costs in metroareas allow only the productive firms to survive. We use a firm-dynamics model with alocation choice to quantify the extent to which the three theories explain the data. Wefind the first two theories largely explain the high growth among metro, young firms. Ourmodel also suggests the distortion in entrepreneurs’ location choice can induce substantialwelfare loss.


Common Power Laws For Cities And Spatial Fractal Structures, Tomoya Mori, Tony E. Smith, Wen-Tai Hsu Mar 2020

Common Power Laws For Cities And Spatial Fractal Structures, Tomoya Mori, Tony E. Smith, Wen-Tai Hsu

Research Collection School Of Economics

City-size distributions are known to be well approximated by power laws across a wide range of countries. But such distributions are also meaningful at other spatial scales, such as within certain regions of a country. Using data from China, France, Germany, India, Japan, and the United States, we first document that large cities are significantly more spaced out than would be expected by chance alone. We next construct spatial hierarchies for countries by first partitioning geographic space using a given number of their largest cities as cell centers and then continuing this partitioning procedure within each cell recursively. We find …


Uncertainty, Depreciation And Industry Growth, Roberto Samaiego, Juliana Yu Sun Nov 2019

Uncertainty, Depreciation And Industry Growth, Roberto Samaiego, Juliana Yu Sun

Research Collection School Of Economics

When investment is irreversible, firms invest only when the mismatch between their productivity and their capital stock is large. This suggests that two factors should be related to the frequency of mismatch: volatility and capital depreciation. A canonical model of industry dynamics with investment irreversibility displays slow growth in times of high uncertainty, and decline is particularly pronounced in industries where capital depreciation is rapid. A differences-in-differences regression using industry growth data from a large sample of countries supports this result.


Tax Uncertainty And Business Activity, Jungho Lee, Jianhuan Xu Jun 2019

Tax Uncertainty And Business Activity, Jungho Lee, Jianhuan Xu

Research Collection School Of Economics

We investigate the extent to which uncertainties about tax policies affect business activities. We develop a statewide tax-uncertainty measure (TU measure) and show that it captures state corporate tax uncertainty. By comparing adjacent counties across state borders, we show that increasing tax uncertainty by one standard deviation (a 30% increase in the TU measure) leads to a 0.17% point per-year decrease in the growth rate of establishments over two years. The result holds after conducting a variety of robustness checks and is not likely to be driven by general state-policy uncertainties.


Does Foreign Direct Investment Lead To Industrial Agglomeration?, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu Mar 2019

Does Foreign Direct Investment Lead To Industrial Agglomeration?, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu

Research Collection School Of Economics

This paper studies the effect of foreign direct investment (FDI) on industrial agglomeration.Using the differential effects of FDI deregulation in 2002 in China on different industries, we find that FDI actually affects industrial agglomeration negatively. This result is somewhat counter-intuitive, as the conventional wisdom tends to suggest that FDI attracts domestic firms to cluster for various agglomeration benefits, in particular technology spillovers. To reconcile our empirical findings and the conventional wisdom, we develop a theory of FDI and agglomeration based on two counter-veiling forces. Technology diffusion from FDI attracts domestic firms to cluster, but fiercer competition drives firms away. Which …


Competition, Markups, And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu Jan 2019

Competition, Markups, And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu

Research Collection School Of Economics

This paper provides a quantitative analysis of gains from trade in a model with head-to-head competition using Chinese firm-level data from Economic Censuses in 1995 and 2004. We find a significant reduction in trade cost during this period, and total gains from such improved openness during this period is 7:1%. The gains are decomposed into a Ricardian component and two pro-competitive ones. The procompetitive effects account for 20% of the total gains. Moreover, the total gains from trade are 13 31% larger than what would result from the formula provided by ACR (Arkolakis, Costinot, and Rodríguez-Clare 2012), which nests a …

When Does Limited Commitment Matter In A Production Economy?, Kyoung Jin Choi, Jungho Lee May 2018

When Does Limited Commitment Matter In A Production Economy?, Kyoung Jin Choi, Jungho Lee

Research Collection School Of Economics

We investigate the conditions under which the first-best allocation without commitment is sustainable in a production economy. While it is widely known in the literature that allowing capital accumulation creates a distortion, we find that it can help to sustain the first-best allocation. We also find that for a certain set of endowment economiesin which the efficient allocation is not sustainable, the efficient allocation becomes sustainable once we introduce a production technology with very small returns to scale orany returns to scale higher than that of the minimum value. In some cases, gains fromefficient resource allocation between agents can be …


Research Note: Investor Perceptions Of Comparable-To-Industry Versus Higher-Than-Industry Pay Ratio Disclosures, Khim Kelly, Jean Lin Seow Mar 2018

Research Note: Investor Perceptions Of Comparable-To-Industry Versus Higher-Than-Industry Pay Ratio Disclosures, Khim Kelly, Jean Lin Seow

Research Collection School Of Accountancy

The usefulness of the CEO-to-employee pay ratio disclosure to investors is subject to significant debate. Our experiment examines participant responses to higher-than-industry and comparable-to-industry pay ratio disclosures in a company. A prior experiment by Kelly and Seow (2016) (hereafter KS) found that incrementally disclosing a higher-than-industry pay ratio on top of higher-than-industry CEO pay had indirect negative effects on the company’s perceived investment potential, via negative perceptions about the fairness of the CEO pay and workplace climate. We find that the negative indirect effects of pay ratio disclosures on perceived investment potential in KS are replicable in our study, and …


Resource Scarcity, Effort, And Performance In Physically Demanding Jobs: An Evolutionary Explanation, Marko Pitesa, Stefan Thau Mar 2018

Resource Scarcity, Effort, And Performance In Physically Demanding Jobs: An Evolutionary Explanation, Marko Pitesa, Stefan Thau

Research Collection Lee Kong Chian School Of Business

Based on evolutionary theory, we predicted that cues of resource scarcity in the environment (e.g., news of droughts or food shortages) lead people to reduce their effort and performance in physically demanding work. We tested this prediction in a 2-wave field survey among employees and replicated it experimentally in the lab. In Study 1, employees who perceived resources in the environment to be scarce reported exerting less effort when their jobs involved much (but not little) physical work. In Study 2, participants who read that resources in the environment were scarce performed worse on a task demanding more (carrying books) …


In Good Company: In The Future, Every Business Might Be Social, Christian Petroske Jan 2018

In Good Company: In The Future, Every Business Might Be Social, Christian Petroske

Social Space

It sounds like a riddle: why would Coca Cola, one of the biggest soft drinks companies in the world, be investing in a cause to empower fi ve million female entrepreneurs globally by 2020? It’s true:1 the Coca Cola Company’s initiative, called 5by20, is a forerunning example of a trend sweeping the corporate world. This trend is known by many names, the foremost of which are “shared value”, “inclusive business” or “sustainable business”. Their defi nitions can seem murky at fi rst, but these terms share a common thread. They sit at the intersection of economy and society, one that …


On The Relationship Between Household Wealth And Entrepreneurship, Jungho Lee Aug 2017

On The Relationship Between Household Wealth And Entrepreneurship, Jungho Lee

Research Collection School Of Economics

Motivated by a substantial number of startup owners with negative household net worth, I present a model that incorporates credit borrowing into Evans and Jovanovic [1989]. The estimated model generates no relationship between household wealth and the propensity for business entry. Ignoring credit borrowing for potential business owners substantially overstates the efficiency loss from financial constraints in business entry. However, the efficiency loss in investments by the entrants is large even if credit borrowing is allowed. Individuals who start a business once credit borrowing is available are those whose business ideas are of a high-enough quality to compensate high financing …


Does Wage-Inflation Targeting Complement Foreign Exchange Intervention? An Evaluation Of A Multi-Target, Two-Instrument Monetary Policy Framework, Taojun Xie, Jingting Liu, Joseph D. Alba, Wai-Mun Chia Apr 2017

Does Wage-Inflation Targeting Complement Foreign Exchange Intervention? An Evaluation Of A Multi-Target, Two-Instrument Monetary Policy Framework, Taojun Xie, Jingting Liu, Joseph D. Alba, Wai-Mun Chia

Research Collection Lee Kong Chian School Of Business

We assess the inclusion of wage inflation as an intermediate target of an emerging central bank using a dynamic stochastic general equilibrium model with sticky wages and prices calibrated for the South Korean economy. The model includes wage inflation as an additional target jointly with domestic price inflation and the output gap in a Taylor- type interest rate rule operating with a sterilized foreign exchange (FX) intervention rule. Our results show a complementary relationship between wage inflation targeting and price inflation targeting. That is, by supplementing price inflation targeting with wage inflation targeting, welfare improves for cases with and without …
