  1. Fiscal contraction is linked to lower NPLs in the long run
    Study shows fiscal consolidation reduces non-performing loans long-term but increases them temporarily, using bank data from Guyana. Oil prices and efficiency matter most.
  2. Lack of allocative efficiency improvement explains much of the slowdown
    Analysis shows allocative efficiency deterioration, driven partly by sectoral volatility, explains most US productivity slowdown in the 1970s and 2000s.
  3. Airfare variation in South Africa is shaped more by distance and airline type
    Analyze airfare volatility across South Africa's domestic airline market. Study reveals low-cost carriers charge less per km than full-service carriers; route distance matters more than booking.
  4. Inflation volatility in Tunisia depends on fiscal coordination and transparency
    Explore how central bank independence and transparency affect inflation volatility in small open economies like Tunisia through game theory and empirical analysis.
  5. Dynamic price monitoring improved affordability forecasting in Lusaka
    Study on Dynamic Price Monitoring forecasting household affordability of essential commodities in Lusaka, Zambia, using household survey and price data analysis.
  6. China coal prices show stable long-term links across market variables
    Analysis of China's steam coal price formation reveals that port inventory, shipping costs, and oil prices drive pricing dynamics more than production alone, with implications for energy policy.
  7. SOI spillovers were strongest for SAFEX maize
    Time-frequency analysis of Southern Oscillation Index spillovers to grain futures reveals regional asymmetries in climate vulnerability, with SAFEX maize showing significant SOI predictive capacity.
  8. TV-SCVARMA outperforms classical VARMA in Nigeria
    Time-varying VARMA framework for macroeconomic forecasting in Nigeria addresses parameter instability from external shocks using state-space estimation with Kalman filtering.
  9. Spline-based score-driven models allow flexible time-varying parameters
    Score-driven time-varying parameter model using spline-based densities without parametric assumptions, with applications to inflation and volatility filtering.
  10. Destination structures and export stability varied across major wheat suppliers
    Analyzing how destination diversification and competitiveness shape wheat export resilience among major suppliers during pandemic, climate, and geopolitical shocks from 2020-2024.
