Bubbly Booms And Welfare, Feng Dong, Yang Jiao, Haoning Sun

Research Collection School Of Economics

We show the competing effects of a housing bubble on the real economy by developing a multi-sector dynamic model with housing production. On the one hand, firms can sell or collateralize their housing, so a housing bubble helps firms obtain credit to finance their investment and expand production. On the other hand, a boom in the housing sector crowds out labor in the non-housing sector. We show that housing booms can reduce social welfare both in the steady state and in the transitional dynamics only when the production externalities in the non-housing sector are sufficiently large. We quantitatively evaluate our …

Robust Testing For Explosive Behavior With Strongly Dependent Errors, Yui Lim Lui, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

A heteroskedasticity-autocorrelation robust (HAR) test statistic is proposed to test for the presence of explosive roots in financial or real asset prices when the equation errors are strongly dependent. Limit theory for the test statistic is developed and extended to heteroskedastic models. The new test has stable size properties unlike conventional test statistics that typically lead to size distortion and inconsistency in the presence of strongly dependent equation errors. The new procedure can be used to consistently time-stamp the origination and termination of an explosive episode under similar conditions of long memory errors. Simulations are conducted to assess the finite …

Optimal Nonparametric Range-Based Volatility Estimation, Tim Bollerslev, Jia Li, Qiyuan Li

Research Collection School Of Economics

We present a general framework for optimal nonparametric spot volatility estimation based on intraday range data, comprised of the first, highest, lowest, and last price over a given time-interval. We rely on a decision-theoretic approach together with a coupling-type argument to directly tailor the form of the nonparametric estimator to the specific volatility measure of interest and relevant loss function. The resulting new optimal estimators offer substantial efficiency gains compared to existing commonly used range-based procedures.

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 …

Cross-Border Technology Investments In Recession, Juliana Yu Sun, Huanhuan Zheng

Research Collection School Of Economics

Utilizing industry-level foreign direct investment (FDI) from 72 source markets to 122 destination markets between 2003 to 2018, we evaluate how cross-border technology investments respond to economic recessions. We find that FDI embedded with intensive research and development (R&D) drops when the destination market is in a recession and the source market is in a normal state and recovers to the pre-recession levels when both destination and source markets are in recession. However, there is little evidence that recessions affect cross-border investments in other aspects of technology measured by the penetration of robots, intellectual property products and information and communications …

Housing Fever In Australia 2020-23: Insights From An Econometric Thermometer, Shuping Shi, Peter C. B. Phillips

Research Collection School Of Economics

Australian housing markets experienced widespread and, in some cases, extraordinary growth in prices between 2020 and 2023. Using recently developed methodology that accounts for fundamental economic drivers, we assess the existence and degree of speculative behaviour, as well as the timing of exuberance and downturns in these markets. Our findings indicate that speculative behaviour was indeed present in six of the eight capital cities at some time over the period studied. The sequence of events in this nation-wide housing bubble began in the Brisbane market and concluded in Melbourne, Canberra, and Hobart following the interest rate rise implemented by the …

Disagreement In Market Index Options, Guilherme Salome, George Tauchen, Jia Li

Research Collection School Of Economics

We generate new evidence on disagreement among traders in the S&P 500 options market from high-frequency intraday price and volume data. Inference on disagreement is based on a model where investors observe public information but agree to disagree on its interpretation; disagreement among investors is captured by the volume–volatility elasticity. For options, there are two natural variables related to disagreement: moneyness and tenor, which we relate to disagreement about the distribution of the market index at different quantiles and times. The estimated volume–volatility elasticity equals unity for options near the money and close to expiration, which is consistent with the …

Bubble Testing Under Polynomial Trends, Xiaohu Wang, Jun Yu

Research Collection School Of Economics

This paper develops the asymptotic theory of the least squares estimator of the autoregressive (AR) coefficient in an AR(1) regression with intercept when data is generated from a polynomial trend model in different forms. It is shown that the commonly used right-tailed unit root tests tend to favor the explosive alternative. A new procedure, which implements the right-tailed unit root tests in an AR(2) regression, is proposed. It is shown that when the data generating process has a polynomial trend, the test statistics based on the new procedure cannot find evidence of explosiveness. Whereas, when the data generating process is …

Political Connections, Informational Asymmetry, And The Efficient Resolution Of Financial Distress, Madhav S. Aney, Sanjay Banerji

Research Collection School Of Economics

We show that securities issued by a distressed firm, often through exchange offers, providethe most efficient resolution of financial restructuring. Information asymmetry between thefirm-bank coalition and small bondholders gives rise to other forms of distress resolutionsuch as refinancing, public workout, and the inefficiency of liquidation. We find that politicallobbying by the firm-bank amplifies these inefficiencies and inhibits the development of privatemarket for distressed securities. Cross-country evidence is consistent with this and indicatesthat improved creditor rights, and information facilitating credit bureaus interact in reducingthe likelihood of inefficient distress resolution.

What, Why And How Financial Development Matters: Evidence Of Asean-5, Asia-5 And Oecd-7 Economies, Swee Liang Tan

Research Collection School Of Economics

This paper analyzed the association between bank and capital markets financial development with income per capita in three regions; ASEAN-5 economies (Singapore, Malaysia, Thailand, Philippines, Indonesia), Asia-5 (Japan, China, Hong Kong SAR, South Korea, and India), and OECD-7 (Australia, Canada, Denmark, Norway, Sweden, UK, and US) from 2000 to 2017 using panel data regressions. A key lesson ASEAN-5 can learn from Asia-5 and OECD-7 experience is that bank size does matter despite digital disruptions to their banking system; yet large financial structure that favors banks is negatively associated with Asia-5, and importantly, efficient banking system (not bank size alone) is …

Bank, Stock Market Efficiency And Economic Growth: Panel Data Evidence From Asean-5, Asia-5 And Oecd-7 Countries, Swee Liang Tan

Research Collection School Of Economics

This paper estimates bank and stock market efficiency associations with real per capita GDP growth by examining panel-data across three different regions using Beck-Katz Panel-Corrected Standard Errors (PCSE) regression. It allows heteroskedastic and/or contemporaneously correlated disturbances across panels, with to specify a common first-order autocorrelation within the panel. The results suggest efficiency effects on growth is not unambiguous. The results suggest a threshold beyond which increase in bank overhead cost hurts economic growth, for developing countries. Likewise, there is a threshold beyond which increase in stock market turnover ratio hurts economic growth, for developed countries. One policy implication of the …

A Panel Clustering Approach To Analyzing Bubble Behavior, Yanbo Liu, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This study provides new mechanisms for identifying and estimating explosive bubbles in mixed-root panel autoregressions with a latent group structure. A post-clustering approach is employed that combines a recursive k-means clustering al-gorithm with panel-data test statistics for testing the presence of explosive roots in time series trajectories. Uniform consistency of the k-means clustering algorithm is established, showing that the post-clustering estimate is asymptotically equivalent to the oracle counterpart that uses the true group identities. Based on the estimated group membership, right-tailed self-normalized t-tests and coefficient-based J-tests, each with pivotal limit distributions, are introduced to detect the explosive roots. The usual …

Vat Treatment Of The Financial Services: Implications For The Real Economy, Ismail Baydur, Fatih Yilmaz

Research Collection School Of Economics

Financial institutions are exempt from the value-added tax (VAT) in most countries. We develop a general equilibrium model with endogenous firm entry and a banking sector to accommodate three key distortions related to exempt treatment: (i) self-supply bias in the banking sector, (ii) under-taxation of payment services, and (iii) input distortions in the business sector and tax cascading. We calibrate our model to the average of Germany, France, and the UK data. Our results show that repealing exempt treatment always increases tax revenues. However, welfare gains occur only at low VAT rates due to the hump-shaped VAT Laffer curve.

Achieving Price Stability, Hwee Kwan Chow, Taojun Xie

Research Collection School Of Economics

The aim of delivering medium-term price stability is the stated objective of the Monetary Authority of Singapore. To this end, the central bank adopted an unusual exchange rate–based monetary policy framework that has served the economy well over the past decades. However, the shift from the phase of catch-up growth to a mature economy raises the question of whether the current monetary policy framework needs reformulation. Moreover, as global financial integration deepens, surges in cross-border capital flows impact Singapore’s exchange rate and asset prices, which has implications for economic dynamism and inclusion. Since a large and persistent deviation of the …

Financing Singapore’S Smes And The Crowdfunding Industry In Singapore, Swee Liang Tan, Yoke Wang Tok, Chansriniyom Thitipat

Research Collection School Of Economics

As new digital technologies emerge that make the provision of financial services more efficient, they hold the potential to address barriers that SMEs face in accessing credit. This paper finds empirical evidence that crowdfunding for SMEs improved SMEs’ timeliness to pay debt in Singapore. Anecdotal evidence from growing SMEs suggests that getting crowdfunding loans also induced financing from banks, leading to more efficient allocation of credit. In just four years, Singapore’s crowdfunding volume has grown rapidly making it one of the top crowdfunding hubs in Southeast Asia in 2018. The rapid development of Singapore’s crowdfunding industry can be attributed to …

Connectedness Of Asia Pacific Forex Markets: China's Growing Influence, Hwee Kwan Chow

Research Collection School Of Economics

This paper investigates the degree of connectedness of Asia Pacific forex markets post global financial crisis and relates it to developments in the renminbi markets. The connectedness measure developed by Diebold and Yilmaz (2014) reveal the strength of linkages across the US dollar currency pairs of twelve currencies, namely offshore renminbi, onshore renminbi, euro, yen, Australian dollar, Indian rupee, Korean won, Malaysian ringgit, New Zealand dollar, Singapore dollar, Thai baht and Taiwan dollar. With the gradual liberalization of China’s exchange rate system, shocks from the renminbi markets contribute more to fluctuations in almost all individual Asia Pacific currency markets vis-a-vis …

A Hybrid Equity Release Plan For Retirement Financing, Koon Shing Kwong, Yiu Kuen Tse, Junxing Chay

Research Collection School Of Economics

There are two main equity release plans for retirement financing: reverse mortgage plan and home reversion plan. Both plans entitle the homeowners not only to release cash from their properties but also to allow them living there for life. In the lease buyback scheme (LBS) recently introduced in Singapore, the home owner sells the tail-end of the property lease to the government in exchange for a cash payment upfront. Unlike the two main equity release plans, the LBS only allows the owner to stay in the property for the front part of the lease but not for life.

In this …

Informal Institutions And Comparative Advantage Of South-Based Mnes: Theory And Evidence, Pao-Li Chang, Yuting Chen

Research Collection School Of Economics

This paper builds a theory based on “informal institutions” to characterize the comparative advantage of South-based MNEs. MNEs headquartered in countries with poorer state institutions are shown to endogenously invest more in firm-specific institutional capital to compensate for the lack of state institutions, and as an optimal response, undertake FDI in countries with weaker institutions. We conduct an extensive test of the theory using worldwide firm-level greenfield FDI flows during 2009–2016, employing (among others) variations in the interaction of prevalence of informal institutions at home and state institutional qualities of host countries, as well as heterogeneity across sectors and firms …

Does Early Access To Pension Wealth Improve Health?, Seonghoon Kim, Kanghyock Koh

Research Collection School Of Economics

We examine the health impacts of early access to public pension wealth by exploiting a unique policy in Singapore allowing individuals to withdraw a proportion of their pension savings after their 55th birthday. For the identification, we employ a regression discontinuity design by comparing individuals before and after their 55th birthday. To address anticipated and lagged health impacts, we adopt the donut regression discontinuity approach. Using nationally representative monthly panel data, we find that early access to pension wealth improves self‐reported overall health.

Digital Payments And Consumption: Evidence From The 2016 Demonetization In India, Sumit Agarwal, Pulak Ghosh, Jing Li, Tianyue Ruan

Research Collection School Of Economics

We study how consumer spending responds to digital payments, using the differential switch to digital payments across consumers induced by the sudden 2016 Indian Demonetization for identification. Usage of digital payments rose by 3.38 percentage points and monthly spending increased by 3% for an additional 10 percentage points in prior cash dependence. Spending remained elevated even when cash availability recovered. Robustness analyses show that the spending response is not driven by income shocks, credit supply, price changes, or consumers' moving to the formal market. We provide evidence that digital payments increase consumer spending due to subdued salience.

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.

Cross-Border Technology Investments In Recessions, Juliana Yu Sun, Huanhuan Zheng

Research Collection School Of Economics

Utilizing industry-level foreign direct investment (FDI) from 72 source markets to 122 destination markets between 2003 to 2018, we apply a differences-in-differences approach to evaluate the response of technology FDI to recessions. We find that research and development (R&D) intensive FDI drops when the destination market is in recession and the source market is in a normal state, and recovers to the pre-recession levels when both destination and source markets are in recession. The result is particularly pronounced in deep and long recessions, during the propagation stage of recessions, and in destination markets with stronger intellectual property protection, looser FDI …

Geography, Trade And Power-Law Phenomena, Pao-Li Chang, Wen-Tai Hsu

Research Collection School Of Economics

This article reviews interrelated power-law phenomena in geography and trade. Given the empirical evidence on the gravity equation in trade flows across countries and regions, its theoretical underpinnings are reviewed. The gravity equation amounts to saying that trade flows follow a power law in distance (or geographic barriers). It is concluded that in the environment with firm heterogeneity, the power law in firm size is the key condition for the gravity equation to arise. A distribution is said to follow a power law if its tail probability follows a power function in the distribution’s right tail. The second part of …

Forecasting Realized Volatility Using A Nonnegative Semiparametric Model, Anders Eriksson, Daniel P. A. Preve, Jun Yu

Research Collection School Of Economics

This paper introduces a parsimonious and yet flexible semiparametric model to forecastfinancial volatility. The new model extends a related linear nonnegative autoregressive modelpreviously used in the volatility literature by way of a power transformation. It is semiparametric inthe sense that the distributional and functional form of its error component is partially unspecified.The statistical properties of the model are discussed and a novel estimation method is proposed.Simulation studies validate the new method and suggest that it works reasonably well in finitesamples. The out-of-sample forecasting performance of the proposed model is evaluated against anumber of standard models, using data on S&P 500 …

Marginal Cost Of Risk-Based Capital And Risk-Taking, Tao Chen, Jing Rong Goh, Shinichi Kamiya, Pingyi Lou

Research Collection School Of Economics

We explore the impact of capital adequacy requirements on financial institutions' risk-taking behavior from a novel perspective. Specifically, we show that an important feature of the risk-based capital (RBC) system a built-in diversification benefit in aggregating risk categories induces moral hazard. We find that insurers that face lower marginal RBC costs of fixed-income (FI) investment tend to purchase riskier Fl securities. This relationship holds even when lower marginal RBC costs result from increased risk in other risk categories, which is an unintended consequence of the RBC's square root rule. Using Hurricanes Katrina and Sandy as exogenous shocks to the RBC …

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 …
