What the literature leaves open

  • The study identifies a gap in the literature on the relationship between R&D expenditure and nominal GDP growth in developing and transition economies. The paper recognizes that the growth effects of R&D are likely to depend on absorptive capacity, institutional conditions, and the structure of the national innovation system.

  • Giuliano Toshiro Yajima Levy Economics Institute https://orcid.org/0000-0002-7529-060X

    Reverse technological specialization, late resource curse and inequality: the US perspective · 2026 · DOI

  • There are mixed findings, ‘productivity paradox’ depends on the kind of knowledge factors and firm attributes.

  • The study identifies a gap in the existing literature by examining the impact of innovation on economic growth across country groups. The research investigates whether innovation affects economic growth and whether this effect varies according to country income groups.

  • The paper identifies a gap in the understanding of the relationships between savings, investment, capital accumulation, and productivity at the macroeconomic level. The study aims to fill this gap by providing a structured approach to understanding how savings influence labour productivity.

    Savings, Investment, Capital to Labour Ratio and Labour Productivity in the European Union over the Period 2000–2022 · 2026 · DOI

  • Future research could address these limitations by employing longer time se- ries, incorporating additional countries, or conducting disaggregated analyses at the sectoral or regional level. Additionally, the study does not account for potential structural breaks, policy changes, or external shocks that could influence the relationships under investigation.

  • The study does not receive any grant from a funding institution. The funding is covered by the authors' own expense. The study may have limitations due to the lack of external funding.

    ECONOMIC GROWTH DRIVERS: EMPIRICAL FINDINGS FOR DEVELOPING EUROPEAN COUNTRIES · 2026 · DOI

  • Traditional economic growth models do not fully capture the complexity of contemporary economic realities.

The study seeks to identify the key factors contributing to economic growth.

    ECONOMIC GROWTH DRIVERS: EMPIRICAL FINDINGS FOR DEVELOPING EUROPEAN COUNTRIES · 2026 · DOI

  • There has been an extensive amount of research devoted to innovative activity in universities, and not much research is done on the factors of higher education influencing the innovative activity of enterprises. The study aims to fill this gap by evaluating the effect of the major higher education institutional factors on the innovative activity of enterprises in the country.

    ASSESSING THE IMPACT OF HIGHER EDUCATION FACTORS ON INNOVATIVE ACTIVITY OF ENTERPRISES: AN ARDL APPROACH · 2026 · DOI

  • There is a lack of studies on the impact of innovation on firm productivity in the Middle East and North Africa region. Prior studies have found variable results on the relationship between innovation and firm productivity.

    THE IMPACT OF INNOVATION ON FIRM PRODUCTIVITY: NEW EVIDENCE FROM THE WORLD BANK ENTERPRISE SURVEY · 2026 · DOI

  • Future research should investigate the role of public policies in shaping innovation and economic growth. It should explore the relationship between creative destruction, innovation, and productivity growth.

    Spinning Jennies and Silicon: The Economics of Innovating or Evaporating – Creative Destruction and Public Policies · 2026 · DOI

  • The paper identifies a gap in our understanding of the relationship between innovation, economic growth, and public policies. It argues that the current literature does not fully explain the productivity slowdown in advanced OECD economies.

    Spinning Jennies and Silicon: The Economics of Innovating or Evaporating – Creative Destruction and Public Policies · 2026 · DOI

  • Future research should cover emerging economies and discuss the role of disruptive technologies. Future research should employ instrumental variable analysis or the GMM technique to address the limitation of endogeneity.

    THE IMPACT OF HIGH-TECH EXPORTS ON ECONOMIC GROWTH IN G-8 COUNTRIES: EXAMINING THE INNOVATION - GROWTH NEXUS · 2026 · DOI

  • The study identifies a gap in the understanding of the relationship between high-tech export and economic growth in G-8 countries. The study aims to fill this gap by investigating the factors that influence this relationship.

    THE IMPACT OF HIGH-TECH EXPORTS ON ECONOMIC GROWTH IN G-8 COUNTRIES: EXAMINING THE INNOVATION - GROWTH NEXUS · 2026 · DOI

  • There is little understanding of how the supply and demand sides of international financial integration work together in a world with heterogeneous firms and expenditure elasticities of demand. The study aims to fill this gap by assessing the effects of international financial flows on resource allocation.

    The Micro and Macro Dynamics of Capital Flows · 2026 · DOI

  • Achieving the 3% GDP target for R&D expenditure in the EU. Bridging the innovation gap between the EU27 and Slovakia. Enhancing technological upgrading and long-term competitiveness.

    Econometric analysis and forecasting of R&D intensity as a basis for a comparative study of Slovakia and the EU27 towards 2030 targets · 2026 · DOI

  • The EU27 and Slovakia have a significant innovation gap. The current linear trend indicates that neither will achieve their 2030 R&D intensity targets.

    Econometric analysis and forecasting of R&D intensity as a basis for a comparative study of Slovakia and the EU27 towards 2030 targets · 2026 · DOI

  • The study identifies a gap in the understanding of the relationship between digitalization and productivity growth in Indonesia. The study highlights the limitations of ordinary regression models in capturing the non-linear relationship between digitalization and productivity growth.

    An Application of the Quantile Regression Model to the Relationship Between Digitalization and Productivity Growth in Indonesia · 2026 · DOI

  • Future research should investigate the impact of digitalization on specific aspects of human capital development. The study suggests further analysis of the relationship between technological innovation and human capital development in different contexts.

    The Impact of Innovative Technologies on Increasing the Competitiveness of Human Capital in the Agricultural Economy · 2026 · DOI

  • The paper identifies a gap in the understanding of the impact of innovative technologies on human capital. The study highlights the need for further research on the relationship between digitalization and human capital development.

    The Impact of Innovative Technologies on Increasing the Competitiveness of Human Capital in the Agricultural Economy · 2026 · DOI

  • The study only analyzes data from 2018 to 2022. The study focuses on developed economies, with limited insights into emerging economies. The correlation analysis may not capture the complexities of the relationships between R&D investment, export performance, and GDP growth.

    R&D Investment and Export Performance as Drivers of Sustainable GDP Growth: Evidence from Developed Economies · 2026 · DOI

  • Future studies can examine the relationships between R&D investment, export performance, and GDP growth in emerging economies. Future studies can use more advanced methodologies to capture the complexities of the relationships. Future studies can explore the role of other factors, such as institutional frameworks and policy environments, in shaping the relationships.

    R&D Investment and Export Performance as Drivers of Sustainable GDP Growth: Evidence from Developed Economies · 2026 · DOI

  • The complexity of macroeconomic dynamics. The need for a comprehensive understanding of the relationships between macroeconomic variables. The challenge of designing resilient strategies for inclusive prosperity.

    Determinants of Gross Domestic Product: A Structural Equation Modeling · 2026 · DOI

  • The paper identifies a gap in the existing literature by working with a more general notion than endomorphism, namely endogenies. It shows that the action of two infinite commuting invariant rings of endomorphisms of a finite-dimensional virtually connected irreducible bi-module linearizes into a vector space over a definable field.
