What the study found
Public debt was found to have a detrimental impact on economic growth in Türkiye. The authors also report that their nonlinear model shows a U-shaped relationship between public debt and economic growth, with a 61-63% threshold.
Why the authors say this matters
The authors conclude that increasing public debt to stimulate growth is not a viable policy. They suggest borrowing should be used for productive investments that raise output and employment rather than for financing budget deficits.
What the researchers tested
The study examined the public debt and economic growth relationship in Türkiye from 1968 to 2019. The researchers used the Fourier-Augmented ARDL methodology, which is a time-series approach that can account for possible structural changes and nonlinear patterns.
What worked and what didn't
The analysis showed that public debt had a negative effect on economic growth in both linear and nonlinear models. These findings remained consistent after robustness checks. The nonlinear model differed from most prior findings by indicating a U-shaped relationship and a 61-63% threshold.
What to keep in mind
The abstract does not describe detailed limitations beyond the country and period studied. The results are specific to Türkiye over 1968-2019, so the abstract does not claim they apply everywhere.
