What the study found
The study found that price level, interest rate spread, and regulatory quality were related to foreign direct investment (FDI) in the BRICS and GCC country groups, but the patterns differed across groups and between the short run and the long run. The authors report positive and negative associations in different cases, depending on the estimator and region.
Why the authors say this matters
The authors conclude that the findings improve understanding of how large interest rate spreads and high price levels can shift foreign investment amounts, which they describe as important for balanced economic growth. They also say countries should address institutional conditions and regulatory frameworks before trying to stimulate FDI.
What the researchers tested
The researchers carried out a comparative panel-data analysis of four BRICS countries and four GCC countries over 2005 to 2023, using 76 observations in each group. They examined the effects of interest rate spread, regulatory quality, and price level on FDI, and used second-generation panel methods because of cross-sectional dependence, including the CIPS unit root test, Westerlund cointegration with bootstrap, and long-run estimators such as PMG and CCEMG.
What worked and what didn't
In BRICS, the PMG estimator showed a significantly positive short-run relationship between price level and FDI. In the GCC, the PMG estimator showed a significantly positive long-run relationship between interest rate spread and FDI, and significantly negative long-run relationships between price level and FDI and between regulatory quality and FDI. As a robustness check, CCEMG also showed a significantly positive long-run relationship between price level and FDI and a significantly negative long-run relationship between regulatory quality and FDI in BRICS, while the GCC CCEMG results were consistent with PMG for regulatory quality, interest rate spread, and price level.
What to keep in mind
The abstract does not provide the full country list beyond noting that India, the UAE, and Saudi Arabia were excluded because of unavailable data. It also does not describe the size or direction of effects in numerical detail, only whether relationships were statistically significant and positive or negative.
- The study examined FDI in four BRICS countries and four GCC countries from 2005 to 2023.
- Price level was significantly positively related to FDI in the BRICS short run in the PMG results.
- In the GCC, interest rate spread was significantly positively related to FDI in the long run, while price level and regulatory quality were significantly negatively related to FDI in the PMG results.
- Robustness checks with CCEMG showed a positive long-run price level–FDI link and a negative long-run regulatory quality–FDI link in BRICS.
- The authors say countries should address institutional conditions and regulatory frameworks before trying to stimulate FDI.
