Abstract for: Sovereign debt and export: endogenous and exogenous oscillations

This research examines the interconnected dynamics of the international trade (export) and public debt cycles within the economy of Ukraine using system dynamics approach. The main objective of the research is to investigate the relationship between foreign trade and the public debt cycle. It is presumed that Ukraine is experiencing a significant overshoot of its stable long-term public debt ratio. We use system dynamics approach to find the relationship between international trade(export) and public debt cycles. In the article we use the context of Ukraine as an emerging market. We'vebeen making an attempt to reveal the factos, which contribute to the challenges of sovereign debt limit capacity with the connection of export capacity of national economy. There are fluctuations, determined by domestic and international factors: economic capacity (export) and debt overhang We present an "overshoot and collapse" model and suggest that there may be substantial cycles of fluctuation in public debt and exports relative to GDP. Endogenus and exogenous reasons of fluctuations between export and sovereign debt are still insufficiently understood. By emphasizing the relationships between export capacity and sovereign debt, this research contributes to a further research of economic instability and the potential for default situations resolution. This study has scientific and applied value, as it allows specialists in the field of foreign economic activity and international finance to systematically analyze the dynamics of national external debt in its relationship with external debt and make appropriate decisions.
