Abstract:
Background: Government borrowings could play an important role
in maintaining economic stability; however, it is essential to keep the
indebtedness manageable to ensure that debts continue contributing to
economic growth. This concern is particularly relevant for the Philippine
economy, which has faced recurring economic shocks, policy transitions, and
fluctuating debt trajectories over the past decades.
Methods: This study analyzed the relationship between the debt-to-GDP ratio
and GDP growth in the Philippines from 1986 to 2020, employing regression
and correlation analyses to determine the optimal debt ratio. A quadratic
regression model, demonstrating the highest adjusted R2
and lowest MSE,
revealed a U-shaped non-linear relationship. It suggests an optimal debtto-GDP ratio of 57.64% when including extraordinary events and 60.23%
excluding them.
Results: Spearman's correlation indicated a significant negative correlation
between debt and growth at lower debt levels. In comparison, the relationship
at higher debt levels was inconclusive, highlighting the influence of external
shocks and domestic policies. The study identified periods characterized by
varying debt and growth dynamics, illustrating the complex interplay of natural
disasters, financial crises, fiscal policies, and global economic conditions.
Conclusion: Ultimately, the findings emphasize the context-dependent
nature of the debt-growth nexus, advocating for nuanced policy responses
tailored to the Philippines' specific economic environment. These insights
inform more adaptive fiscal policymaking in the Philippine context and
offer implications for other emerging economies dealing with similar debt
sustainability challenges.
