Deep Roots of Fiscal Behavior by Serhan Cevik, Katerina Teksoz

“…In addition, the paper finds that macro-financial factors (such as real exchange rate, financial development, interest rates, asset prices, and natural resource rents) and demographic and institutional factors (such as the old-age dependency ratio, the quality of institutions, and policy anchors such as fiscal rules and IMF-supported stabilization programs) tend to have a significant effect on fiscal policy behavior. …”

Belize’s 2016–17 Sovereign Debt Restructuring – Third Time Lucky? by Tamon Asonuma, Michael G. Papaioannou, Eriko Togo, Bert van Selm

“…As was the case in the earlier two restructurings, in 2006–07 and in 2012–13, the 2016–17 debt restructuring was executed through collaborative engagement with creditors outside an IMF-supported program. While providing liquidity relief and partially addressing long-term debt sustainability concerns, the restructuring will need to be underpinned by ambitious fiscal consolidation and growth-enhancing structural reforms to secure durable gains and avoid future debt distress situations.…”
