Open research questions in Economic theories and models

50 unresolved questions extracted from the limitations and future-work sections of 2,061 Economic theories and models papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • The paper suggests that future research could focus on empirical applications of the theoretical model. The paper implies that further analysis of the dynamics of real savings per capita could be fruitful. The paper does not provide explicit suggestions for future research directions.

    Existence and calculation of optimal monetary equilibria on overlapping generations economies · 2026 · DOI

  • The paper identifies a gap in the literature regarding the existence of optimal monetary equilibria. The paper notes that prior work has focused on the efficiency of equilibria, but not their existence. The paper aims to fill this gap by providing sufficient conditions for the existence of optimal monetary equilibria.

    Existence and calculation of optimal monetary equilibria on overlapping generations economies · 2026 · DOI

  • Future research should continue to develop the theory of general equilibrium. It should explore the implications of fixed-price equilibria. The paper suggests that further study of temporary equilibrium models is needed.

    Developments in the theory of general equilibrium · 1983 · DOI

  • The paper identifies a gap in the understanding of general equilibrium theory. It notes that the theory is not yet fully developed. The paper seeks to contribute to the development of general equilibrium theory.

    Developments in the theory of general equilibrium · 1983 · DOI

  • Further exploration of the conditions of existence of a two-class economy. Investigation of the implications of the results for growth and income distribution. Development of more realistic and plausible saving functions.

    Conditions of Existence of a Two Class Economy in the Kaldor and More General Models of Growth and Income Distribution · 1983 · DOI

  • The lack of clarity on the analytical issues surrounding the savings function. The need for a general savings function that reduces to prior models under certain conditions.

    Conditions of Existence of a Two Class Economy in the Kaldor and More General Models of Growth and Income Distribution · 1983 · DOI

  • Future research could examine the impact of changes in student grants on the supply decision. Future research could examine the effects of allowing for differences in hours worked and fringe benefits.

    RATES OF RETURN: SOME FURTHER RESULTS* · 1983 · DOI

  • The gap in the literature is the lack of examination of movements over time in observed rates of return. The gap in the literature is the lack of guidance on whether further investment in this type of human capital is worthwhile.

    RATES OF RETURN: SOME FURTHER RESULTS* · 1983 · DOI

  • The paper identifies a gap in the understanding of the labor market. The paper critiques the notion that the marginal product curve is the demand curve for labor.

    The Marginal Product Curve Is Not the Demand Curve for Labor and Lucas’s Labor Supply Function Is Not the Supply Curve for Labor in the Real World · 1983 · DOI

  • The paper identifies a gap in the existing literature regarding the demand for money and liquidity preference. The paper argues that the traditional view of the demand for money is too narrow and fails to account for the use of money in financing the exchange of existing assets.

    A Post Keynesian View of Liquidity Preference and the Demand for Money · 1983 · DOI

  • The gap between Allyn Young's insights and the dominant neoclassical economics. The lack of consideration of growth and change in traditional economic models.

    Allyn Young on Increasing Returns · 1983 · DOI

  • The challenge of predicting the future course of economic events using econometric models. The challenge of understanding the behavior of economies undergoing endogenous trade cycles.

    Economic Policy and Endogenous Cycles · 1983 · DOI

  • The econometric models have a poor track record in predicting the future course of economic events. The model used is highly simplified and may not accurately represent real-world economies.

    Economic Policy and Endogenous Cycles · 1983 · DOI

  • The paper identifies a gap in the existing literature, highlighting the need for a more nuanced understanding of the relationship between finance, investment, and saving. The authors highlight the importance of considering the liquidity position of the banking system when making investment decisions.

    Kalečki and Keynes on finance, investment and saving · 1983 · DOI

  • Future research could consider other types of shocks or models. It could analyze the implications of different information structures for macroeconomic models.

    SOME IMPLICATIONS OF PARTIAL CURRENT INFORMATION SETS IN MACROECONOMIC MODELS EMBODYING RATIONAL EXPECTATIONS * · 1983 · DOI

  • The paper identifies a gap in the literature regarding the effectiveness of monetary policy in models with rational expectations. It notes that prior work has not considered the implications of partial current information sets.

    SOME IMPLICATIONS OF PARTIAL CURRENT INFORMATION SETS IN MACROECONOMIC MODELS EMBODYING RATIONAL EXPECTATIONS * · 1983 · DOI

  • The paper identifies a gap in the understanding of Kalecki's Degree of Monopoly theory. The theory has been often misrepresented or ignored.

    Kalecki’s Degree of Monopoly · 1983 · DOI

  • The paper suggests that future research should focus on developing new models that can address the challenges posed by a depressed natural real interest rate. The paper also suggests that future research should focus on analyzing the potential practical implications of the model.

    The trilemma for low interest rate macroeconomics · 2026 · DOI

  • The paper identifies a gap in the literature on the challenges of macroeconomic policy when the natural real interest rate is persistently depressed. The paper argues that the traditional response to this challenge is not sufficient to address the challenge.

    The trilemma for low interest rate macroeconomics · 2026 · DOI

  • The lack of tools that combine quantitative risk analysis with classical economic assumptions. The lack of tools that account for the strength of market fluctuations.

    Modeling the impact of demand, supply, and budget constraints on consumer preferences · 2026 · DOI

  • The lack of conditions for finite inference in the equilibrium setting. The lack of a learning algorithm to infer individual choices and equilibrium prices.

    Exact inference from finite market data · 2026 · DOI

  • Future research can apply the Symboken Theory to real-world scenarios. It can explore the implications of symbolic inflation for the economy. The theory can be used to analyze the impact of artificial intelligence on the economy.

    The Symboken Theory · 2026 · DOI

  • The increasingly difficult to defend assumptions of modern quantitative finance, - The lack of a deeper theoretical framework for modern quantitative finance

    Resource Holonomy: Market Stability and the Critical Line of Economic Coherence · 2026 · DOI

  • Students accept the First Law/Energy Conservation Principle but have difficulty learning and understanding the Second Law, entropy, entropy generation, and their consequences.

    Analogy to help learn and understand the second law of thermodynamics, entropy, entropy generation, irreversibility, and power cycles · 2024 · DOI

  • We show that in this setting (a) the economy may get stuck in a high-unemployment steady state, (b) the Taylor principle is insufficient to eliminate the local indeterminacy of the intended steady state, and (c) nominal rigidities and inincomplete markets are complementary in terms of amplifying the impact of shocks on the macroeconomy.
