What the literature leaves open

  • The existing literature does not provide a timely and detailed estimate of GDP. The delay in GDP releases makes it difficult to observe the present state of the economy. The paper identifies a need for a methodology that can generate model-consistent estimates for missing observations in the flow of data.

    Masked macroeconomic nowcasting · 2026 · DOI

  • The NARDL results indicate that, during this period, INFR− (declining inflation) had a mildly positive point estimate but was insufficient to offset the external shock.

    Inflation Threshold for Vietnam: Evidence from Threshold Regression and NARDL with Quarterly Data · 2026 · DOI

  • Future research could explore similar analyses using other globally traded homogeneous goods to further validate these findings. As such, we have constructed a new dataset, consisting of APPs, as well as their associated transaction or input costs, to evaluate what relationships and dynamics (that have not been explored in existing publications) can be revealed.

  • Future research could address these limitations through dynamic or causal modelling and rolling or expanding forecast evaluations over multiple economic regimes.

  • Future research should examine institutional-digital complementarities through interaction and nonlinear models and assess whether the observed pattern extends to other energy-rich emerging economies.

    Institutional and Digital Predictors of Private Sector Credit in Azerbaijan: An Elastic Net Approach · 2026 · DOI

  • Although the Gaussian forecasting framework provides a practical and stable approach in the present small-sample setting, several alternative modeling strategies could be explored in future research.

  • The study does not address the potential limitations of the Regularized Vector Autoregressive models. The study does not provide a detailed analysis of the robustness of the results.

    Regularized Vector Autoregressive Model for the Assessment of Macroeconomic Variables Associated with Inflation in Nigeria · 2026 · DOI

  • There is a gap in literature on the application of regularized methods to study inflation in Nigeria. Most studies on inflation in Nigeria rely on the traditional VAR model and do not adequately address multicollinearity.

    Regularized Vector Autoregressive Model for the Assessment of Macroeconomic Variables Associated with Inflation in Nigeria · 2026 · DOI

  • The relationship between trade deficits and public debt is complex and not well understood. There is a need for effective fiscal and monetary policymaking to support long-term debt sustainability.

    Assessing the impact of trade deficits on public debt in Asian economies under inflation volatility · 2026 · DOI

  • The lack of empirical evidence on the relationship between parallel market exchange rate premiums and retail pricing strategies in South Sudan. The need to understand the impact of exchange rate dynamics on retail business performance.

    Parallel market premiums as retail pricing determinants: Empirical evidence from South Sudan's dual exchange rate economy · 2026 · DOI

  • There is a lack of studies examining the impact of monetary policy announcements on exchange rate volatility in emerging markets. The paper identifies a gap in the literature regarding the comparison of the impacts of advanced and emerging market economies' monetary policies on exchange rate volatility.

    Monetary Policy and Exchange Rate Volatility of the Mexican Peso Against the US Dollar · 2026 · DOI

  • Future research can apply the proposed model to other financial datasets. Future research can explore the use of other estimation methods. Future research can investigate the use of the model in other fields.

    Large‐Dimensional Cointegrated Threshold Factor Models: The Global Term Structure of Interest Rates · 2026 · DOI

  • The paper identifies a need for a model that can account for cointegration between group-specific factors.

    Large‐Dimensional Cointegrated Threshold Factor Models: The Global Term Structure of Interest Rates · 2026 · DOI

  • The study highlights the need for a comprehensive meta-analysis of the interest rate pass-through.

  • Further research could investigate the economic impact of public expenditures in other sectors. Further research could use different methodologies to estimate the economic impact of arms procurement.

    Sectoral Investment in Input-Output Frameworks, a Reply · 2026 · DOI

  • The paper notes that households do not perfectly observe current realizations of wages and inflation. The paper assumes that households receive noisy signals of wages and inflation. The paper models the subjective expectations of households and firm managers under limited attention.

    The Inflation Attention Threshold and Inflation Surges · 2026 · DOI

  • The empirical literature on monetary policy transmission to output and inflation remains inconclusive, with varying results stemming from differences in the choice of policy variables and methodologies.

    Monetary policy transmission in India – a coefficient-restricted VAR approach · 2025 · DOI

  • Annual macroeconomic data often contain relatively few observations and limited short-term fluctuations. The true shape of the Phillips curve is not a universal constant but a country-specific attribute. The paper identifies frequent shifts in economies such as France and Italy, likely reflecting a history of localized structural breaks and policy regime changes.

    Mathematical Computation of Piecewise Linear Regression with Endogenous Segmentation for Accurate Data-Based Model Building: An Example of the Phillips Curve · 2026 · DOI

  • The current approaches do not capture gradual shifts in macroeconomic relationships and account for heteroskedasticity across parameters.

    The Phillips Curve and Inflation Expectations: A Machine Learning Perspective · 2026 · DOI

  • The authors note that prior work has focused on the inter-temporal channel that affects the consumption and savings plans of households, but has neglected the intratemporal allocation between consumption and leisure.
