We study a dynamic stopping game between a principal and an agent. The agent is privately informed about his type. The principal learns about the agent’s type from a noisy performance measure, which can be manipulated by the agent via a costly and hidden action. We fully characterize the unique Markov equilibrium of this game. We find that terminations/ market crashes are often preceded by a spike in (expected) performance. Our model also predicts that, due to endogenous signal manipulation, too much transparency can inhibit learning. As the players get arbitrarily patient, the principal elicits no useful information from the …

International Asset Pricing With Strategic Business Groups, Massimo Massa, Hong Zhang, Hong Zhang
International Asset Pricing With Strategic Business Groups, Massimo Massa, Hong Zhang, Hong Zhang
Research Collection Lee Kong Chian School Of Business
Firms in global markets often belong to business groups. We argue that this feature can have a profound influence on international asset pricing. In bad times, business groups may strategically reallocate risk across affiliated firms to protect core “central firms.” This strategic behavior induces co-movement among central firms, creating a new intertemporal risk factor. Based on a novel data set of worldwide ownership for 2002–2012, we find that central firms are better protected in bad times and that they earn relatively lower expected returns. Moreover, a centrality factor augments traditional models in explaining the cross section of international stock returns.

We show that ongoing zero portfolio weights in cryptocurrency are surprisingly difficult to generate in a standard Bayesian portfolio theory framework. With ten years of prior data, equity market investors would need very pessimistic priors on mean returns to justify never having bought cryptocurrency: -10.6% per month for Bitcoin, and -19.6% per month for a diversified portfolio of cryptocurrencies. Moreover, most priors that involve never purchasing cryptocurrency imply that investors should short cryptocurrency. Optimal absolute weights are generally small but non-trivial (1-5%), frequently positive, and fairly smooth despite returns being volatile. Under a wide range of priors, the certainty equivalent …
Customer Concentration And Corporate Carbon Emissions, Saiying Deng, Tinghua Duan, Frank Weikai Li, Xiaoling Pu
Customer Concentration And Corporate Carbon Emissions, Saiying Deng, Tinghua Duan, Frank Weikai Li, Xiaoling Pu
Research Collection Lee Kong Chian School Of Business
This paper examines whether economic links with major corporate customers curb corporate carbon emissions. We show that supplier firms with a concentrated customer base have significantly lower carbon emissions. The baseline results are robust to alternative measures of carbon emissions and customer concentration, and various approaches that mitigate endogeneity concerns due to omitted variables and reverse causality. Moreover, the curbing effect of customer concentration on supplier carbon emissions is more pronounced in firms facing lower customer switching costs, with less (more) supplier (customer) bargaining power, fewer redeployable assets, operating in more carbon-intensive industries, and after the Paris Agreement of 2015. …
Inflation Expectations Can Be A Self-Fulfilling Prophecy, Aurobindo Ghosh, Khyati Chauhan, Muskan Bagrodia
Inflation Expectations Can Be A Self-Fulfilling Prophecy, Aurobindo Ghosh, Khyati Chauhan, Muskan Bagrodia
Research Collection Lee Kong Chian School Of Business
In a commentary, SMU Assistant Professor of Finance (Education) Aurobindo Ghosh, SMU postgraduate student and Research Assistant for the SInDEx Project Muskan Bagrodia and International Monetary Fund Economic Research Assistant Khyati Chauhan weighed in on why inflation expectations matter as much as economic data. They discussed how inflation expectations can be a self-fulfilling prophecy, and shared the key takeaways of the quarterly DBS-Sim Kee Boon Institute’s Singapore Index of Inflation Expectations (DBS-SKBI SInDEx) survey. They concluded that effective communication on inflation control measures, in addition to credible policy decisions, will help consumers feel assured and refrain from basing purchasing decisions …
Oil Price Shocks And Stock Market Anomalies, Zhaobo Zhu, Licheng Sun, Jun Tu, Qiang Ji
Oil Price Shocks And Stock Market Anomalies, Zhaobo Zhu, Licheng Sun, Jun Tu, Qiang Ji
Research Collection Lee Kong Chian School Of Business
This paper provides a novel perspective to the nexus of oil prices and stock markets by examining the impact of oil price shocks on stock market anomalies. After decomposing oil price shocks into three types , we find that aggregate demand shocks have the strongest influence on stock market anomalies. In contrast, oil supply shocks and oil-specific demand shocks have little impact. Similar results are also found in the industry analysis. Interestingly, the link between aggregate demand shocks and anomalies is the strongest among firms with either small size or high idiosyncratic risks. The documented effects are robust after controlling …

Eradicating Malaria: Innovation Diffusion In The Face Of Grand Challenges, Han Jiang, Hao Liang, Dongning Yang
Research Collection Lee Kong Chian School Of Business
What is the role of organizational innovation—beyond technological innovation—in an era of grand challenges concerning health, poverty, and economic development around the world? How is organizational innovation developed and diffused to influence resource allocation in the field? We conduct a qualitative case study by analyzing a Chinese pharmaceutical firm’s efforts to combat malaria in Africa over 10 years. Through documentation and extensive interviews, we study the role of innovation diffusion and resource allocation to address grand challenges in emerging markets with significant institutional voids. Our conceptual model delineates the different stages of innovation diffusion to show how organizations can draw …

Capital expenditures of U.S. public firms, relative to total assets, decrease by more than half from 1980 to 2020. The decline is pervasive across industries and firms of different characteristics and cannot be explained by the usual determinants of investment and many other seemingly plausible reasons. The decline is consistent with the transformation in production technology — firms rely more on intangible capital and less on fixed assets in production. Industry-level analyses yield supporting evidence. We observe similar declining trend in capital expenditure in other developed countries but not in most emerging markets.
Internal Capital Markets And Predictability In Complex Ownership Firms, Ran Chang, Angelica Gonzalez, Sergei Sarkissian, Jun Tu
Internal Capital Markets And Predictability In Complex Ownership Firms, Ran Chang, Angelica Gonzalez, Sergei Sarkissian, Jun Tu
Research Collection Lee Kong Chian School Of Business
Using global cross-firm ownership data, we find that both stock returns and cash-flow news of ownership-linked firms predict focal firm's returns for all types of ownership structures: subsidiary-parent, parent-subsidiary, subsidiary-subsidiary, and parent-parent. This effect, observed only after the establishment of cross-firm ownership, is not subsumed by focal firm or industry momentum, or alternative inter-firm relations, including customer-supplier links and shared analyst coverage. Our findings are explained by mispricing due to internal capital markets - a mechanism unique to complex ownership firms. Higher internal capital market activity among ownership-linked firms also induces larger investments and lower external financing of the focal …

To cope with the negative oil futures price caused by the COVID-19 recession, global commodity futures exchanges switched the option model from Black-Scholes to Bachelier in April 2020. This study reviews the literature on Bachelier's pioneering option pricing model and summarizes the practical results on volatility conversion, risk management, stochastic volatility, and barrier options pricing to facilitate the model transition. In particular, using the displaced Black-Scholes model as a model family with the Black-Scholes and Bachelier models as special cases, we not only connect the two models but also present a continuous spectrum of model choices.

Inflation And Ukraine War Make It Challenging For Our Beloved Value Stores To Survive, Aurobindo Ghosh, Taimur Baig
Research Collection Lee Kong Chian School Of Business
In a joint commentary, SMU Assistant Professor of Finance (Education) and Principal Investigator of DBS-SKBI Singapore Index of Inflation Expectations Project Aurobindo Ghosh and Chief Economist and Managing Director at DBS Bank Dr Taimur Baig discussed how global inflationary pressures and rising commodity prices due to war in Ukraine and sanctions against Russia are culminating into a perfect storm and making it challenging for value stores to survive. They also gave advice on what value stores can do to survive this perfect storm.

Do Underwriters Short-Change Corporations Issuing Bonds?, Choo Yong, Jeremy Goh, Lisa Yang
Research Collection Lee Kong Chian School Of Business
We confirm prior evidence that bonds on average are offered at prices below their immediate post-offer secondary market prices. However, in cases where banks lead-manage their own bond offerings the underpricing is significantly less as compared to other non-self-marketed offerings. These findings are robust across various matched samples and selection models. Our results suggest that the bond offering process is characterized by substantive agency conflicts between shareholders of corporations (issuers) and underwriters.

Why Commonality Persists?, Chyng Wen Tee, Raja Velu, Zhaoque Zhou

We show that order flows do not exhibit predictive power on asset returns, and their relationships have been static over time. We use a reduced-rank regression formulation to model both returns and the order flows as endogenous variables, and use investors' sentiment and attention as exogenous factors. We provide empiricalevidence 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 attentionmeasures themselves exhibit a nonlinear mutual relationship, thus revealing the multi-dimensional aspect of the commonality relationship.

This study investigates the impact of investor sentiment on excess equity return forecasting. A high (low) investor sentiment may weaken the connection between fundamental economic (behavioral-based non-fundamental) predictors and market returns. We find that although fundamental variables can be strong predictors when sentiment is low, they tend to lose their predictive power when investor sentiment is high. Non-fundamental predictors perform well during high-sentiment periods while their predictive ability deteriorates when investor sentiment is low. These paradigm shifts in equity return forecasting provide a key to understanding and resolving the lack of predictive power for both fundamental and non-fundamental variables debated …

Capital constraints of financial intermediaries can affect liquidity provision. We investigate whether these constraints spillover and consequently cause contagion in the degree of market efficiency across assets managed by a common intermediary. Specifically, we provide evidence of strong comovement in pricing gaps between ETFs and their constituents for ETFs served by the same lead market maker (LMM). The effects are stronger for ETFs that are more illiquid and volatile, when the underlying constituents of the ETFs are more costly to arbitrage, and for LMMs with more constrained capital. Using extreme disruptions in debt markets during COVID-19 as an experiment, we …
How Do Firms Respond To Reduced Private Equity Buyout Activity?, Yi-Hsin Lo
How Do Firms Respond To Reduced Private Equity Buyout Activity?, Yi-Hsin Lo
Research Collection Lee Kong Chian School Of Business
This paper presents new evidence on the economic role of private equity buyouts by exploiting the staggered adoption of the constructive fraud provision by U.S. state courts. The law unintentionally shifts the credit default risk borne by existing unsecured creditors of the buyout target to the selling shareholders and lenders in the form of ex-post litigation risk, thereby discouraging buyout activity. Using a difference-in-differences framework, I find that firms raise less capital, reduce payouts and investments, and form alliances with employees. Firms also avoid positive NPV projects that carry too much risk. These findings are consistent with managers enjoying a …

We hypothesize that social trust, in mitigating contracting incompleteness, may have an important effect on the activeness and effectiveness of delegated portfolio management. Using a complete sample of worldwide open-end mutual funds, we find that trust is positively associated with the activeness of funds and that trust-related active share delivers superior performance (e.g., approximately 2% per year for cross-border investments). Moreover, "trust in the market" and "trust in managers" play important yet different roles for different types of cross-border delegated portfolio management. Our results suggest that trust acts as a fundamental building block for delegated portfolio management.

We provide novel evidence that arbitrageurs use exchange-traded funds (ETFs) as an avenue to circumvent short-sale constraints at the stock level. Using a large sample of U.S. equity ETF holdings, we document that shorting activity on ETFs rises with the difficulty of shorting underlying stocks. Stocks heavily shorted via their holding ETFs underperform those that are lightly shorted. The return predictability of ETF shorting is distinct from stock-level shorting measures and is concentrated among stocks that face severe arbitrage constraints. These findings suggest that ETFs allow arbitrageurs to target overpriced stocks that are otherwise difficult to short.

Climate Change And Sustainability In Asean Countries, David K. Ding, Sarah E. Beh
Research Collection Lee Kong Chian School Of Business
The ASEAN region is one of the most susceptible regions to climate change, with three of its countries—Myanmar, the Philippines, and Thailand—among those that have suffered the greatest fatalities and economic losses because of climate-related disasters. This paper reveals that the ASEAN’s environmental performance is sorely lagging other regions despite evidence of its cohesive and comprehensive efforts to mitigate emissions and build up adaptive capacity to climate-related disasters. Within the ASEAN, there exist gaps in environmental performance between each country. This suggests that increased cooperation between individual ASEAN countries is pertinent for the region to collectively combat climate change. In …
