  • “America First,” Fiscal Policy, and Financial Stability

    Strategic Analysis, April 2018 | April 2018
    The US economy has been expanding continuously for almost nine years, making the current recovery the second longest in postwar history. However, the current recovery is also the slowest recovery of the postwar period.

    This Strategic Analysis presents the medium-run prospects, challenges, and contradictions for the US economy using the Levy Institute’s stock-flow consistent macroeconometric model. By comparing a baseline projection for 2018–21 in which no budget or tax changes take place to three additional scenarios, the authors isolate the likely macroeconomic impacts of: (1) the recently passed tax bill; (2) a large-scale public infrastructure plan of the same “fiscal size” as the tax cuts; and (3) the spending increases entailed by the Bipartisan Budget Act and omnibus bill. Finally, Nikiforos and Zezza update their estimates of the likely outcome of a scenario in which there is a sharp drop in the stock market that induces another round of private-sector deleveraging.

    Although in the near term the US economy could see an acceleration of its GDP growth rate due to the recently approved increase in federal spending and the new tax law, it is increasingly likely that the recovery will be derailed by a crisis that will originate in the financial sector.

  • Quantitative Easing and Asset Bubbles in a Stock-flow Consistent Framework

    Working Paper No. 897 | September 2017
    Ever since the Great Recession, central banks have supplemented their traditional policy tool of setting the short-term interest rate with massive buyouts of assets to extend lines of credit and jolt flagging demand. As with many new policies, there have been a range of reactions from economists, with some extolling quantitative easing’s expansionary virtues and others fearing it might invariably lead to overvaluation of assets, instigating economic instability and bubble behavior. To investigate these theories, we combine elements of the models in chapters 5, 10, and 11 of Godley and Lavoie’s (2007) Monetary Economics with equations for quantitative easing and endogenous bubbles in a new model. By running the model under a variety of parameters, we study the causal links between quantitative easing, asset overvaluation, and macroeconomic performance. Preliminary results suggest that rather than being pro- or countercyclical, quantitative easing acts as a sort of phase shift with respect to time.

  • Stock-flow Consistent Macroeconomic Models

    Working Paper No. 891 | May 2017
    A Survey

    The stock-flow consistent (SFC) modeling approach, grounded in the pioneering work of Wynne Godley and James Tobin in the 1970s, has been adopted by a growing number of researchers in macroeconomics, especially after the publication of Godley and Lavoie (2007), which provided a general framework for the analysis of whole economic systems, and the recognition that macroeconomic models integrating real markets with flow-of-funds analysis had been particularly successful in predicting the Great Recession of 2007–9. We introduce the general features of the SFC approach for a closed economy, showing how the core model has been extended to address issues such as financialization and income distribution. We next discuss the implications of the approach for models of open economies and compare the methodologies adopted in developing SFC empirical models for whole countries. We review the contributions where the SFC approach is being adopted as the macroeconomic closure of microeconomic agent-based models, and how the SFC approach is at the core of new research in ecological macroeconomics. Finally, we discuss the appropriateness of the name “stock-flow consistent” for the class of models we survey.
