Lead Research Organisation:
University of Birmingham
Department Name: Economics
Abstract
In 2019, the UK ranks as Taiwan's 3rd largest trading partner in Europe, while Taiwan is the UK's 7th largest trading partner in Asia (Taiwan's Ministry of Foreign Affairs). As the Brexit transition period ends and the UK will be able to develop its own independent trade policies, Taiwan and the UK have sought to boost trade and strengthen the economic partnership between the two countries in recent rounds of bilateral trade talks.
As both countries are small open economies trading next to a large neighbouring economy that is also their main trading partner, namely China and the EU, respectively, Taiwan and the UK stand to benefit from having a joint academic network that can share best practice and facilitate knowledge exchange between two trade teams that already have access to highly disaggregate transactional-level customs trade data and firm-level financial data for Taiwan and the UK.
This project aims to establish a close working partnership through the development of three work packages. The first package is to initiate closer networking by establishing a close working relationship between the two trade teams for (i) sharing experience in working with confidential customs data and discussing scope for data sharing through a launch event, (ii) training early career researchers who will be working with big data through a workshop, and (iii) engaging with wider research communities and policy audience through a closing conference to disseminate our research output.
Our second work package will initiate joint research activities with a research project on how different traders respond differently in terms of international pricing in response to external shocks such as exchange rate movements. In particular, we will focus on two aspects of trader characteristics in both countries (i) firms' financial constraints and (ii) firms' dependence on the largest trading partners (China for Taiwanese firms and the EU for UK firms), in explaining firms' pricing strategies. We will take an innovative approach to identify these characteristics for both countries in the context of Taiwan-UK bilateral trade, and our findings will have strong policy implications for small open economies when making inflation forecasts or predicting the effectiveness of monetary policy.
Finally, our third forward-looking package will develop a 3-year plan as Areas of Interest for Taiwan-UK trade 2023-2026, to be advertised with a designated social media account. We will also seek to develop policy impact, for instance, by promoting potential bilateral trade facilitating policies such as a mutual recognition agreement for each other's trusted traders between Taiwan and the UK.

| Description | 1. Most Significant Achievements from the Award 1.1 High-Level Policy Engagement with Taiwan's Central Bank A major milestone was the invitation to give a seminar talk on exchange rate pass-through at the Central Bank of the Republic of China (Taiwan). This high-level event was hosted directly by the Governor of the Central Bank, Mr. Chin-long Yang, and attended by monetary policymakers, researchers, and postgraduate students from National Taiwan University. • The talk led to an extended Q&A session, where discussions focused on Taiwan's currency invoicing patterns and their implications for exchange rate pass-through into import prices. • Given that the Central Bank lacks access to firm-level currency invoicing data, this engagement significantly enhanced their understanding of these mechanisms. • Future collaboration was requested, particularly in exploring how firm-level pricing data can inform monetary policy decisions. • During the visit, additional discussions were held with Deputy Governor Dr. Chen Nan-kuang and other senior officials to explore potential avenues for strengthening research collaboration between the Central Bank and the international academic community. 1.2 Strengthened UK-Taiwan Academic Collaboration Through Researcher Exchanges • Bilateral Research Visits and Research Presentations: o Researchers from both Taiwan and the UK engaged in mutual visits, fostering deeper academic exchange and policy discussions. o The PI and co-PI presented at multiple institutions in Taiwan, including Academia Sinica, National Taiwan University, Chung-Hua Institute for Economic Research (CIER), and National Tsing Hua University, while team members from Taiwan also visited the UK for research engagement. o Presentations covered key trade and policy topics, including the US-China trade war, green wage premiums, and exchange rate pass-through, sparking discussions with scholars, policymakers, and think tank researchers. • Postgraduate and Early Career Researcher (ECR) Training: o A research engagement event at National Taiwan University facilitated discussions on: ? Big data methodologies for trade analysis ? Linking administrative trade datasets for empirical research ? Refining research questions for policy relevance 1.3 Advancing Joint Research on Exchange Rates and Trade Policy The award facilitated significant research collaboration, culminating in a joint study titled "Dominant Currency Pricing: Do Competitors' Exchange Rates Affect Export Prices?" This research builds on the PI's previous UK-based work on currency of invoicing, extending the analysis to examine how competitors' exchange rates influence export pricing decisions under dominant currency pricing (DCP). • Leveraging Taiwanese customs data from 2010 to 2019, the study investigates how the Korean won (KRW) exchange rate affects the pricing behavior of Taiwanese exporters, given that over 90% of Taiwan's exports are invoiced in USD. • Findings confirm that under DCP, competitors' exchange rates-rather than bilateral exchange rates-play a crucial role in export pricing decisions. Specifically, a depreciation of the KRW against the USD leads to lower Taiwanese export prices, with a stronger effect for firms that export products similar to those of South Korea. • These findings complement the PI's earlier UK-based research, which explored the role of currency invoicing in exchange rate pass-through, further emphasizing how firms' pricing responses depend on both their own invoicing currency and competitive pressures from rival exporters. • This collaboration also led to a new research award of NT$2,172,000 (approx. £55,000) from the National Science and Technology Council, R.O.C. (Taiwan), funding the Taiwan team's project, "Dominant Currency Pricing, Export Price, and Import Price: An Empirical Analysis of Taiwanese Firms." The PI and co-PI are external contributors to this project, further strengthening UK-Taiwan research ties. 2. Extent to Which the Award Objectives Were Met The award successfully met its key objectives by establishing a strong UK-Taiwan academic trade network, advancing joint research, and fostering engagement with policymakers and early career researchers (ECRs). First, the project strengthened institutional ties between UK and Taiwan trade researchers and policymakers. High-level engagement with the Central Bank of Taiwan, think tanks, and academic institutions fostered meaningful discussions on exchange rate pass-through and dominant currency pricing. These interactions provided policymakers with insights that would not have been accessible otherwise, Second, the project made substantial contributions to knowledge sharing and researcher training. ECRs and postgraduate students participated in mentorship, research workshops, and discussions on big data methodologies, equipping them with skills for working with highly disaggregated trade and financial data. Finally, the joint research on competitors' exchange rates and dominant currency pricing delivered significant empirical findings. The study extended previous UK-based research on currency invoicing, offering new insights into how exporters adjust their prices in response to competitor exchange rate movements. The project's success also led to a new research award from the National Science and Technology Council, R.O.C. (Taiwan), supporting further investigation into export and import pricing behavior. 3. Future Steps and Key Stakeholders Collaboration with Taiwan's Central Bank and trade policymakers will continue, ensuring research insights inform monetary policy and trade strategies. Engagement with UK policymakers will also help integrate findings into discussions on dominant currency pricing and post-Brexit trade policies. UK-Taiwan researcher exchanges will deepen empirical work, while workshops and training sessions will further equip early career researchers with expertise in big data analysis and trade modeling. This partnership continues under a new research grant, with the PI and co-PI remaining involved as external contributors, ensuring sustained knowledge exchange and impact. |
| Exploitation Route | Our research outcomes will be taken forward through both academic and policy channels, ensuring impact across research, trade policy, and business decision-making. Academically, findings on dominant currency pricing and competitors' exchange rate effects will contribute to ongoing research in international trade and macroeconomics. Future studies, supported by our new research grant, will extend this work to import pricing behavior, strengthening the UK-Taiwan trade research network and informing scholars working on exchange rate pass-through and trade competitiveness. On the policy side, our engagement with Taiwan's Central Bank and trade policymakers has already enhanced their understanding of currency invoicing and pricing strategies. These insights will support monetary policy adjustments, inflation forecasting, and trade negotiations, particularly regarding exchange rate management and trade facilitation measures. In the UK, policymakers and trade bodies can use our findings to assess post-Brexit trade dynamics and inform bilateral agreements. Our work also has non-academic applications for businesses managing currency risk and export pricing strategies, helping firms adapt to competitor-driven exchange rate fluctuations. Continued collaboration through workshops, researcher training, and stakeholder engagement will ensure long-term impact across academic and non-academic sectors. |

| Results and Impact | I was invited to give a seminar talk on exchange rate pass-through at the Central Bank of the Republic of China (Taiwan). This was considered a high-level event with the talk hosted directly by the Governor of the Central Bank. The audience includes monetary policy makers, researchers, and postgraduate students from National Taiwan University. Following the talk there was a long Q&A session which sparked questions and discussions about Taiwan's currency of invoicing pattern and its implications for exchange rate pass-through into import prices. They reported significant knowledge enhancement (as data available to our team are strictly confidential and the CB has no access to firm-level currency of invoicing pattern, for example), and requested for further engagement in the future. During this visit, I also had the privilege to interact the Governor of the Central Bank of Taiwan, Mr Chin-long Yang, who is also a Birmingham PhD Alumni, for research discussions over lunch (joint by Dr. Jin-tan Liu, Professor of Economics at National Taiwan University). I also met the Deputy Governor, Dr. Chen Nan-kuang, who is also Professor of Economics at National Taiwan University for a discussion on his vision to boost collaborations between the Central Bank and the international research community. |
