Understanding the Dynamics of Global Capital Allocation: A Deep Dive into the Recent NBER Research

Print This Post

In a world where financial boundaries are constantly blurring, understanding the nuances of global capital allocation has never been more critical.

The recent NBER research report by Sergio Florez-Orrego, Matteo Maggiori, Jesse Schreger, Ziwen Sun, and Serdil Tinda sheds light on this intricate landscape, offering a road map for future research and policy implications. Let’s delve into the key takeaways from this comprehensive study.

The Surge in Cross-Border Investments

Over the past few decades, the world has witnessed a substantial increase in cross-border financial positions, with the total value of global cross-border positions soaring from a mere 20% of the world GDP in 1980 to over double the world GDP today. This surge has necessitated a deeper understanding of global asset ownership to navigate the complexities of international macroeconomics and finance.

The Shift Towards Portfolio Investment

The research highlights a significant shift towards portfolio investment, characterized by stocks and bonds, and a decline in “Other” investments, primarily bank lending and cross-border deposits. This trend underscores the growing importance of non-bank financial intermediation in the global financial landscape.

The Role of Currency in International Portfolios

A noteworthy observation in the report is the pivotal role of currency denomination in international portfolios. The study points out a strong asymmetry in lending patterns to firms in large developed countries, with the U.S. dollar emerging as a significant exception, facilitating a higher willingness among foreign investors to invest in dollar-denominated corporate bonds issued by U.S. firms.

Tax Havens and Offshore Financial Centers: The Intermediaries of Global Capital

Tax havens and offshore financial centers play a crucial role in intermediating global capital. The research sheds light on the massive amount of global cross-border investment flowing through these channels, emphasizing the need to look beyond official residency-based statistics to understand the true exposure of investors to large emerging markets, notably China.

The Mystery of “Missing Wealth”

The report brings attention to the discrepancy in international investment statistics, where the world appears as a net debtor by approximately $8 trillion, a phenomenon termed as “missing wealth.” This discrepancy, largely attributed to hidden wealth in tax havens, presents a fertile ground for future research, aiming to unveil the true owners of this concealed wealth.

Looking Ahead: Future Research Directions

As we steer into an era of increasing geopolitical competition, understanding the dynamics of global capital allocation becomes pivotal. The report suggests that future research in this area can unravel the intricacies of investment heterogeneity, international financial market segmentation, and the real effects of tax havens, offering a richer understanding of the global financial system.


The “Global Capital Allocation” report guides researchers, policymakers, and stakeholders through the complex world of international finance. As we stand at the cusp of financial globalization, this research not only offers a deep understanding of the current landscape but also opens avenues for future exploration and is especially relevant to the insurance and asset management industry as a whole.
