ABSTRACT:

The share ownership reform of state-owned commercial banks in China represents a significant milestone in the country’s financial development, playing a significant role in enhancing the efficiency of its financial system and fostering remarkable economic growth in the early 21st century. Based on spatial relationships between bank branches and firms, this study utilizes data from the Annual Survey of Industrial Firms to examine the effects of the share ownership reform on manufacturing firms’ productivity. Our findings indicate a significant improvement in the total factor productivity of firms situated in areas with a higher density of reformed bank branches following the reform, particularly those heavily depend on external financing. Furthermore, this impact is more pronounced among non-state-owned enterprises. The primary mechanism appears to be the increased accessibility of bank credit from state-owned commercial banks, which stimulates firms’ research and development investment as well as patent applications.

Why the Rush? Understanding PCT National Entry from a Real Options Perspective /tongji/smu_sem/semen/26172.html /tongji/smu_sem/semen/26172.html#respond Fri, 09 May 2025 02:58:57 +0000 http://sem.tongji.edu.cn/semen/?p=26172 SPEAKER: 赵敏渊,华盛顿大学圣路易斯分校奥林商学院 副教授

ABSTRACT

The Patent Cooperation Treaty (PCT) offers multinational enterprises (MNEs) a streamlined process for securing global patent protection. By taking the PCT route, MNEs have up to 30 months before deciding whether, when, and where to apply for national patents while preserving the priority rights of their initial filing. In theory, the optimal strategy is to delay this decision until just before the deadline, allowing firms to better assess the technological and market potential of the invention. Surprisingly, however, some firms choose to enter the national phase earlier. Drawing on real options theory (ROT), we propose that this behavior reflects the tension between the intrinsic and time value of the option. Since national patent application outcomes are uncertain and vary by country, early entry may serve as a signal of invention quality, mitigating the uncertainty discount on intrinsic value—but at the expense of time value. Analyzing a dataset of PCT families filed in the global automotive industry between 2010 and 2018, we find supportive evidence that MNEs are more likely to apply national patents early for initial filings in lenient patent offices, for technologies in nascent sectors, or for firms lacking track record in the host country. These findings shed new light on our understanding of global patenting strategies. They also contribute to the ROT literature by highlighting the tradeoff between signaling strength in the present and waiting for clarity in the future.

Beyond Monetization: Heterogeneous Effects of Open Access as a Freemium Strategy for Public Good /tongji/smu_sem/semen/26168.html /tongji/smu_sem/semen/26168.html#respond Fri, 09 May 2025 02:44:39 +0000 http://sem.tongji.edu.cn/semen/?p=26168 SPEAKER: 顾宪博士 美国印第安纳大学布卢明顿分校市场营销学助理教授

ABSTRACT

Open access (OA) provides free digital access to scholarly content without copyright restrictions, aiming to enhance knowledge visibility and accessibility. While increasingly adopted by OA platforms and publishers to broaden consumer reach, open access raises concern about potential revenue loss and fairness, as its impacts on book downloads and sales may differ across authors and consumer groups in ways that are not yet fully understood. This research addresses these issues through a randomized field experiment with a leading digital platform for academic content. Approximately 1,400 book titles were randomly assigned to a control group (no OA) or a treatment group (OA). Despite concerns, we show that open access significantly increases book downloads without reducing book sales on average. However, open access disproportionately reduces sales for books by female authors and has divergent effects across consumers — decreasing sales in lower GDP areas while increasing them in wealthier, more educated regions. Analysis of individual treatment effects reveals substantial heterogeneity: about half of the books experience increased sales, while the other half see declines. Further investigation reveals that open access tends to increase sales for older or less popular books, suggesting that its impact varies based on a book’s existing market presence. Our findings suggest that open access can expand readership without reducing average revenue, offering platforms and publishers a sustainable model to broaden impact. To maximize benefits, platforms and publishers should adopt differentiated release strategies based on a book’s age and popularity and address equity concerns arising from heterogeneous effects across author and consumer socioeconomic backgrounds.

Platform-Generated Quality Ratings: Theory, Empirics and Welfare Implications /tongji/smu_sem/semen/26160.html /tongji/smu_sem/semen/26160.html#respond Wed, 07 May 2025 01:36:59 +0000 http://sem.tongji.edu.cn/semen/?p=26160 SPEAKER:袁哲(浙江大学)

ABSTRACT:

Our study develops and estimates a structural model to analyze the role of platform-generated ratings (PGRs) in shaping consumer choices and seller quality investments. Unlike user-generated ratings, PGRs leverage platform-collected data on product quality, customer service, and logistics, providing consumers with more reliable signals of seller quality. Our model explicitly incorporates consumer consideration set formation, seller quality investment decisions, and the interaction between platform-generated and user-generated ratings. Using novel data that include not only transactional details but also consumer views and clicks, we identify the determinants of consumer consideration set formation. Additionally, unique quality metrics, observable only to the platform, enable us to recover the cost distribution of seller quality investment. Empirically, we employ a regression-discontinuity design to examine consumer responses to high PGR sellers. Our results indicate that customers are more likely to purchase from sellers with high PGRs, confirming their role as effective quality signals. Furthermore, our structural estimation reveals that the presence of PGRs significantly influences sellers’ quality incentives and the equilibrium distribution of quality. A counterfactual analysis suggests that while PGR adoption enhances overall welfare, the relationship between the rating threshold and consumer surplus is non-monotonic—stricter thresholds initially encourage investment but may later deter some sellers from improving quality. Overall, our findings highlight the potential of PGRs to improve market efficiency and consumer welfare by addressing asymmetric information and fostering quality competition among sellers.

The affect-creativity link /tongji/smu_sem/semen/26154.html /tongji/smu_sem/semen/26154.html#respond Mon, 28 Apr 2025 05:55:31 +0000 http://sem.tongji.edu.cn/semen/?p=26154 SPEAKER:胡肖然 助理教授 (英国伦敦政治经济学院)

ABSTRACT

The rapid advancement of artificial intelligence (AI), particularly its growing cognitive prowess, has presented humanity with a profound and unsettling question: What does it truly mean to be human? We contend that two essential qualities continue to define our human identity—our capacity to feel (affect) and our ability to create (creativity). These two dimensions are not only foundational but also deeply intertwined. While creativity (and innovation) is often understood as a cognitive process—where we “create by thinking”—this view overlooks its equally vital emotional dimension. Based on an integration of research spanning over multiple disciplines, we argue that creativity is also a profoundly affective experience: we “create by feeling.”

The Value of Ratings Inflation /tongji/smu_sem/semen/26121.html /tongji/smu_sem/semen/26121.html#respond Fri, 25 Apr 2025 01:43:32 +0000 http://sem.tongji.edu.cn/semen/?p=26121 SPEAKER:高小奕 助理教授,新西兰奥克兰大学

DESCRIPTION

Does ratings inflation help or hurt consumers? Managers? To answer these questions, we build a dynamic pricing model, wherein consumers’ utility depends on product features including the consumer rating that evolves over time. Applying control theory, we compare the pricing strategies with and without ratings inflation. In addition, we empirically validate the model using market data on 10,263 Airbnb properties over four years from Austin, Texas. We find a counter-intuitive result that ratings inflation helps both managers and consumers. Under the dynamic pricing context, ratings inflation helps managers because they earn a higher long-term profit although consumer surplus decreases. However, the ratio of consumer surplus in dynamic pricing relative to that from static pricing increases as ratings increase. Furthermore, the price premium over the static pricing decreases as ratings increase. Consequently, consumers are least worse off when the rating approaches its ceiling value. Hence, ratings inflation helps consumers as well.

Investors’ Risk-taking Behaviors after “Escaping from Death” /tongji/smu_sem/semen/26117.html /tongji/smu_sem/semen/26117.html#respond Mon, 21 Apr 2025 07:56:19 +0000 http://sem.tongji.edu.cn/semen/?p=26117 SPEAKER:张叶青(中央财经大学,副教授)

ABSTRACT

We examine risk-taking behaviors among investors who experienced paper gains during China’s 2007-08 bubble-crash episode, deemed as investors “escaping from death.” Using investor account data from a national brokerage in China, we find that investors who “escaped from death” reduce risk-taking behaviors over the next five years. We exploit plausibly unexpected shocks to investors’ performance during the bubble crash to address the endogeneity inherent in baseline effects analysis. The evidence shows that the change in risk taking is likely attributable to the reference-dependent preferences. However, the effect diminishes over time and investors “escaping from death” do not exhibit a diminished tendency toward risk-taking when confronted with a stock market bubble crash again.

ABSTRACT: 

The rapid advancement of the low-altitude economy (LAE) and urban air mobility (UAM) is reshaping urban development, logistics, and transportation systems. This presentation examines the opportunities, challenges, and policy frameworks driving the future of LAE, integrating cutting-edge research with practical applications.

First, I will introduce the LAE concept, emphasizing its vast potential in global markets, with a special focus on developments in Mainland China and Hong Kong. The discussion will outline key UAM principles and analyze the technical challenges that must be addressed to enable scalable LAE expansion.

Next, I will present our research contributions, including the design and optimization of UAV services for urban inspection, monitoring, and delivery. These case studies demonstrate how UAV technology can enhance operational efficiency and support smart city initiatives.

Finally, I will share insights from the Strategic Public Policy Research Funding (SPPRF) Project, which explores development strategies for an advanced air mobility (AAM) network in the Guangdong–Hong Kong–Macao Greater Bay Area. While interest in AAM is growing, a cohesive policy framework for the region remains underdeveloped. Our research addresses this critical gap by systematically evaluating existing approaches and introducing survey-based insights combined with simulation-driven strategies to establish a robust methodology for accelerating AAM development.

By bridging research, industry applications, and policy development, this presentation offers actionable insights for stakeholders navigating the evolving LAE landscape.

Cross-border M&A, international knowledge flow and global value chain upgrading /tongji/smu_sem/semen/26072.html /tongji/smu_sem/semen/26072.html#respond Fri, 11 Apr 2025 02:29:00 +0000 http://sem.tongji.edu.cn/semen/?p=26072 SPEAKER:葛璐澜(上海立信会计金融学院)

ABSTRACT:

China and countries along the Belt and Road Initiative (BRI) route increasingly undertake cross-border mergers and acquisitions (M&As) and integrating into global value chains (GVCs). While extant research investigates the relationship between cross-border M&As and GVC position, the conclusions remain elusive. Using industry-level panel data covering 38 BRI countries, we demonstrate that cross-border M&As contribute to GVC upgrading, with international knowledge flow playing a positive role. We further show that the positive impact of cross-border M&As on GVC position is stronger in low-tech industries, low R&D strength, financially-developing and low digitalization countries. Moreover, the positive impact is augmented by BRI cooperation. Our research highlights the significance of participating in international investment and acquiring knowledge for BRI countries.
