Market For Manipulable Information, Hui Chen, Jian Sun

Research Collection Lee Kong Chian School Of Business

We study how investors, firms, and information sellers interact in a market with manipulable information. To better predict the firm characteristics they care about, investors can buy a score from a monopolistic information seller, which aggregates signals that are subject to firm manipulation. The average degree of signal manipulability has no effect on the equilibrium, while the uncertainty about manipulability becomes a new source of noise. Its contribution depends on firms' incentive to manipulate the signals, which in turn depends on the equilibrium price sensitivity to the score. The optimal design of the score weighs signal precision against the endogenous …

A Conditional Linear Combination Test With Many Weak Instruments, Dennis Lim, Wenjie Wang, Yichong Zhang

Research Collection School Of Economics

We consider a linear combination of jackknife Anderson-Rubin (AR) and orthogonalized Lagrangian multiplier (LM) tests for inference in IV regressions with many weak instruments and heteroskedasticity. We choose the weight in the linear combination based on a decision-theoretic rule that is adaptive to the identification strength. Under both weak and strong identifications, the proposed linear combination test controls asymptotic size and is admissible. Under strong identification, we further show that our linear combination test is the uniformly most powerful test against local alternatives among all tests that are constructed based on the jackknife AR and LM tests only and invariant …

Modelling Sentiment And Trader Aggressiveness In Cryptocurrency Markets: An Empirical Analysis Of The Bitcoin Limit Order Book., Angelique Nicole Huei Yin Thang

Dissertations and Theses Collection (Open Access)

Cryptocurrency assets are inherently susceptible to social sentiment. Due to emotional contagion, extreme emotions influence and drive traders’ order execution behaviour. This study aims to empirically model the relationship between sentiment and trader aggressiveness for two types of traders: Whales and Retails. Additionally, I uncover the mediating roles of momentum, mean reversion, and market timing underpinning the dynamics of the off-chain Bitcoin market. Time series data collected from the Coinbase level 3 Bitcoin limit order book is first reconstructed to access its core structure. Next, sentiment data from Reddit is extracted and processed using an internal Natural Language Processing pipeline. …

The Relationship Between Reits Industry Characteristics And Project Performance: The Moderating Role Of Macroeconomic Fluctuations, Ying Cai

Dissertations and Theses Collection (Open Access)

As a distinct investment vehicle, Publicly Listed Real Estate Investment Trusts (REITs) projects enable real estate projects to be listed on the stock market. This study begins with the industry attributes of the underlying assets of Publicly Listed REITs projects. Using econometric methods, it analyzes the variances in market performance between growth and defensive REITs, based on annual data from 1,674 REITs products in the United States from 2005 to 2022 and 27 listed REITs in China from Q3 2021 to Q1 2023. The study also leverages the data from China to explore the moderating effects of macroeconomic factors such …

Becoming A Father, Staying A Father: An Examination Of The Cumulative Fatherhood Wage Premium To U.S. Residential Fathers, Ohjae Gowen

Research Collection School of Social Sciences

The instability of fathers’ co-residence with children has become an increasingly prevalent experience for U.S. families. Despite long-standing scholarship examining the relationship between fatherhood and wage advantages, few studies have investigated how variation in fathers’ stable co-residence with a child may produce temporal changes in the wage premium over the life course. Building on prior explanations of the fatherhood wage premium, I test if the wage premium grows with time since the birth of a resident child and if the premium depends on fathers’ co-residence with a child. I use marginal structural models with repeated outcome measures and data from …

The Depth Of Preferential Trade Agreements, Pao-Li Chang, Wei Jin, Kefang Yao

Research Collection School Of Economics

Preferential trade agreements (PTAs) have increased rapidly in number since the 1990s, and have extended their traditional focus on tariff reduction to include deeper integration in policy areas such as competition policy, intellectual property rights, investments, and movement of capital. This paper uses a comprehensive dataset on the content of PTAs to quantify the impacts of the depth of trade agreements on bilateral trade flows and national welfare across the world for the period 1980–2015. The results indicate that agreements that are deeper (by different definitions) contribute to larger trade growth and welfare gains. Furthermore, the results imply that the …

Monetary Transmission And Government Investment In China, Qian Han, Zhaogang Song, Yufei Yuan, Yuanhang Zhao

Research Collection Lee Kong Chian School Of Business

The quantity measure of money supply—the M2 growth, in particular—has been used as the intermediate target of monetary policy in China since 2000. We document three findings on the transmission of money supply shocks to firm investment and financing over the period from 1998 to 2016. First, positive money supply shocks have significant negative effects on firm investment and do not have consistent impacts on firm financing, contradicting the standard monetary transmission mechanism. Second, using short-term global capital flows as an exogenous money supply factor, we recover the standard positive effect of money supply shocks on firm investment and financing, …

China’S Changing Perspective On The Wto: From Aspiration, Assimilation To Alienation, Henry S. Gao

Research Collection Yong Pung How School Of Law

Since its accession to the WTO twenty years ago, China’s image has shifted from a good student aspiring to assimilate itself into the multilateral trading system to one that is increasingly alienated from key WTO principles. How has China’s perspective on WTO been evolving? What are the reasons behind China’s changing perspective? This chapter addresses these questions from the Chinese perspective with a comprehensive analysis of the key moments in China’s first two decades in the WTO, followed by practical suggestions on how to engage China more constructively in the WTO and beyond.

Dynamic Factor Copula Models With Estimated Cluster Assignments, Dong Hwan Oh, Andrew John Patton

Research Collection School Of Economics

This paper proposes a dynamic multi-factor copula for use in high-dimensional time series applications. A novel feature of our model is that the assignment of individual variables to groups is estimated from the data, rather than being pre-assigned using SIC industry codes, market capitalization ranks, or other ad hoc methods. We adapt the k-means clustering algorithm for use in our application and show that it has excellent finite-sample properties. Applying the new model to returns on 110 US equities, we find around 20 clusters to be optimal. In out-of-sample forecasts, we find that a model with as few as five …

Market For Patents, Monopoly, And Misallocation, Shang-Jin Wei, Jianhuan Xu, Ge Yin, Xiaobo Zhang

Research Collection School Of Economics

The paper studies a possible “dark side” of patent trade in enhancing the market power of monopolists. We explore the different effects of China’s 2008 tax reform on patent innovations and sales across industries. In particular, although easier patent trade leads to more patent creation, the new patents are disproportionately connected to existing monopolists and are more likely to be acquired by them. Using an endogenous growth model with patent trade, we show that subsidizing patent trade could skew investors’ research to appeal to the monopolists, increase the latter’s monopoly power, and reduce social welfare. An optimal subsidy policy for …

Are Bond Returns Predictable With Real-Time Macro Data?, Dashan Huang, Fuwei Jiang, Kunpeng Li, Guoshi Tong, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

We investigate the predictability of bond returns using real-time macro variables and consider the possibility of a nonlinear predictive relationship and the presence of weak factors. To address these issues, we propose a scaled sufficient forecasting (sSUFF) method and analyze its asymptotic properties. Using both the existing and the new method, we find empirically that real-time macro variables have significant forecasting power both in-sample and out-of-sample. Moreover, they generate sizable economic values, and their predictability is not spanned by the yield curve. We also observe that the forecasted bond returns are countercyclical, and the magnitude of predictability is stronger during …

How Commonality Persists? (Through Investors' Sentiment And Attention), Chyng Wen Tee, Raja Velu, Zhaoque Zhou

Research Collection Lee Kong Chian School Of Business

Studies on commonality generally attribute the variation in asset returns to the variation in order flows. In this research study, we show that order flows do not predict asset returns, rather their relationship have been static over time. Thus we model both returns and the order flows as endogenous variables, and use investors' sentiment and attention as exogenous factors via a reduced-rank regression. We provide empirical evidence to demonstrate that cross-sectional commonality in attention (sentiment) is linearly (nonlinearly) associated with both returns and order flows at the intraday level, while the sentiment and attention measures themselvesexhibit a nonlinear mutual relationship, …

In Search Of Cryptocurrency Failure, Donglian Ma, Jun Tu, Zhaobo Zhu

Research Collection Lee Kong Chian School Of Business

This paper explores the determinants of cryptocurrency failure and the pricing of crypto failure risk. We document different significant market- and characteristic-based predictors for coin and token failures. The introduction of Bitcoin futures and the outbreak of COVID19 affect the importance of many predictors. Investors require extra return for bearing high failure risk of crypto assets. The return difference across high and low failure risk crypto assets is not explained by the market, size and momentum factors in the cryptocurrency market. Finally, investors benefit from diversifying into high failure risk crypto assets that is little correlated with the stock market.

Gender Divergence In Premarket Skill Acquisition And Wage Inequality, Sunha Myong

Research Collection School Of Economics

I study the changes in premarket skills and the evolution of the wage distribution across two cohorts using the NLSY79 and NLSY97. To estimate the relative importance of changes in premarket skills and changes in skill prices in explaining the evolution of the wage distribution, I apply the DiNardo, Fortin, and Lemieux decomposition method (DiNardo et al. 1996). I find a substantial gender divergence in premarket skill acquisition and wage gain across the two cohorts. Women's wage gain associated with changes in premarket skills is greater than that of men's at all levels of the wage distribution. Changes in premarket …

Yes, it can make or break a society. Elites are an inevitability in society. In recent years, emerging populist movements across different countries have highlighted stark problems with growing.

Decomposability And Strategy-Proofness In Multidimensional Models, Shurojit Chatterji, Huaxia Zeng

Research Collection School Of Economics

We introduce the notion of a multidimensional hybrid preference domain on a (finite) set of alternatives that is a Cartesian product of finitely many components. We demonstrate that in a model of public goods provision, multidimensional hybrid preferences arise naturally through assembling marginal preferences under the condition of semi-separability - a weakening of separability. The main result shows that under a suitable “richness” condition, every strategy-proof rule on this domain can be decomposed into component-wise strategy-proof rules, and more importantly every domain of preferences that reconciles decomposability of rules with strategy-proofness must be a multidimensional hybrid domain.

Information Loss In Volatility Measurement With Flat Price Trading, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

A model of financial asset price determination is proposed that incorporates flat trading features into an efficient price process. The model involves the superposition of a Brownian semimartingale process for the effcient price and a Bernoulli process that determines the extent of price trading. The approach is related to sticky price modeling and the Calvo pricing mechanism in macroeconomic dynamics. A limit theory for the conventional realized volatility (RV) measure of integrated volatility is developed. The results show that RV is still consistent but has an inflated asymptotic variance that depends on the probability of flat trading. Estimated quarticity is …

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 …

Legal Protection Of Property Rights: A Dynamic Evolution Model, Fali Huang

Research Collection School Of Economics

This paper presents an analysis of a dynamic evolution model of institutions, focusing on the factors affecting the security of property rights such as coercive capacity, political power, legal quality, and private protection. These factors are endogenously determined in equilibrium, allowing legal quality to serve as a summary indicator of property security. The primary finding of the study indicates that the legal protection of property rights tends to increase over time, driven by a decline in the economy's vulnerability to expropriation, particularly due to the growing importance of commercial and industrial activities relative to agriculture. Furthermore, the coexistence of the …

Estimating And Applying Autoregression Models Via Their Eigensystem Representation, Leo Krippner

Sim Kee Boon Institute for Financial Economics

This article introduces the eigensystem autoregression (EAR) framework, which allows an AR model to be specified, estimated, and applied directly in terms of its eigenvalues and eigenvectors. An EAR estimation can therefore impose various constraints on AR dynamics that would not be possible within standard linear estimation. Examples are restricting eigenvalue magnitudes to control the rate of mean reversion, additionally imposing that eigenvalues be real and positive to avoid pronounced oscillatory behavior, and eliminating the possibility of explosive episodes in a time-varying AR. The EAR framework also produces closed-form AR forecasts and associated variances, and forecasts and data may be …

Do Government Subsidies Promote Green R&D Efficiency? Empirical Evidence From China, Huimin Wu

Dissertations and Theses Collection (Open Access)

How to evaluate the effects of government policy on encouraging innovations? Existing studies strongly argue to reduce subsidies compared to indirect policy tools, such as tax rebate. However, direct government grants are popular and keep gaining momentum in China. Such a discrepancy between academic research and common practice is interesting and calls for further investigations. In the meantime, is there any difference for this issue if considering green attributes? In this article, we use data from Chinese A-share listed companies to study the effect of government subsidies on R&D activities, with a special focus on comparing green and non-green inventions. …

Limit Theory For Locally Flat Functional Coefficient Regression, Peter C. B. Phillips, Ying Wang

Research Collection School Of Economics

Functional coefficient (FC) regressions allow for systematic flexibility in the responsiveness of a dependent variable to movements in the regressors, making them attractive in applications where marginal effects may depend on covariates. Such models are commonly estimated by local kernel regression methods. This paper explores situations where responsiveness to covariates is locally flat or fixed. The paper develops new asymptotics that take account of shape characteristics of the function in the locality of the point of estimation. Both stationary and integrated regressor cases are examined. The limit theory of FC kernel regression is shown to depend intimately on functional shape …

Does The Federal Reserve Obtain Competitive And Appropriate Prices In Monetary Policy Implementation?, Yu An, Zhaogang Song

Research Collection Lee Kong Chian School Of Business

Many of the Federal Reserve’s (the Fed’s) monetary policy operations involve trading with primary dealers. We find that, for agency MBS, dealers charge 2.5 cents (per $100 face value) higher selling to the Fed than to non-Fed customers. Controlling for the same dealer, same security, and same trading time, this discriminatory pricing likely arises from dealers’ market power rather than inventory costs. Further, matching trade size reduces the price differential by more than half, implying that dealers’ market power greatly relates to the Fed’s purchases in large amounts, whereas the Fed’s limited breadth of counterparty choice also plays some role.

Customer Capital And Trade Intermediaries: Evidence From China, Jungho Lee, Jianhuan Xu

Research Collection School Of Economics

Using a unique dataset that links the production and sales of Chinese exporting firms, we document that the value of export goods a firm produces often differs from the value of export goods that the firm sells in foreign markets. We show that this empirical pattern reflects that some exporters act as trade intermediaries, which we refer to as producer intermediaries. We further show that firms with higher accumulated marketing expenditures are more likely to become producer intermediaries. To understand the implications of our empirical findings, we develop a theoretical framework in which firms can lend and borrow customer capital …

Connecting The (Dirty) Dots: Current Account Surplus And Polluting Production, Jungho Lee, Shang-Jin Wei, Jianhuan Xu

Research Collection School Of Economics

According to the existing open-economy macroeconomics literature, a current account surplus is associated with a welfare loss only when distortions exist in either savings or investment. We propose a new welfare effect even in the absence of such distortions. In our theory, a trade imbalance − the largest component of a current account imbalance − interacts with a country’s pollution control (“cleanness”) regime to generate welfare effects outside the standard channels. In particular, a trade surplus alters the shipping costs and composition of a country’s imports, producing a welfare loss associated with greater pollution.

Tackling Misperceptions About Immigrants With Fact-Checking Interventions: A Randomized Survey Experiment, Syngjoo Choi, Chung-Yoon Choi, Kim

Research Collection School Of Economics

We conduct a randomized online survey experiment to study the impact of fact-checking offers and financial incentives on misperceptions about immigrants. We find that natives overestimate the number of immigrants and the social and economic costs of immigration. Offering a free check of the factual information about immigrants reduces these misperceptions; it becomes more effective when combined with financial incentives. However, more than half of the participants never took up offers to check factual information. Using a model of information search with limited attention, we identify the presence of non-negligible costs of information search and processing, which limits the effectiveness …

The Cost Of Cheap Talk: How Campaign Promises And Default Contributions Affect Donation-Based Crowd Funding Success, Tianci Leon Qiu

Dissertations and Theses Collection (Open Access)

Non-profit organisations (NPOs) find it increasingly harder to engage donors and raise funds from the public. Post-pandemic: the emphasis on tactics to raise funds online through donation-based crowdfunding (DCF) platforms has surged in importance for both NPO survival and continued beneficiary aid. However, unlike equity-based crowdfunding platforms where campaign organisers are obligated to provide investors with tangible returns based on funding milestones, NPOs on DCF platforms do not have to adhere to any funding milestones or are beholden to any tangible obligations towards donors. Consequently, NPOs are greatly incentivised to deploy cheap talk – non-binding, unverifiable messages and claims to …

Do Hacker Groups Pose A Risk To Organizations? Study On Financial Institutions Targeted By Hacktivists, Mikko Samuli Niemelae

Dissertations and Theses Collection (Open Access)

Publication date: 5 September 2023

In the digital era, technological progress has been shadowed by an escalation in cybersecurity threats, notably impacting the financial sector. This research critically examines the influence of hacktivist campaigns—particularly those led by groups like Anonymous—on the cyber exposure of financial services firms listed on the NYSE. Employing Synthetic Controls and analyzing 22 treated firms, the study found that such campaigns significantly enhance the target institutions' deep and dark web exposure, with an average increase of 65% per annum in the subsequent two years from the campaign initiation. Crucially, smaller firms display a heightened susceptibility to …

The Need For Growth, Hian Teck Hoon, Edmund S. Phelps, Gylfi Zoega

Research Collection School Of Economics

The falling rate of productivity growth in the West has made equilibrium real rate of interest fall, causing sky-high stock prices and stagnated real wages. Eliminating or reducing impediments to growth—such as rules and regulations that protect vested interests—would lower the burden of debt, make it easier to reduce greenhouse gas emissions and increase political stability. There are also measures that strengthen institutions that encourage innovations; a healthy financial system, well-protected property rights and values that emphasize self-reliance, independence and good work ethics. While special interests are more entrenched in some developed countries than others, there is hope that current …
