Working Paper No. 958 | June 2020Macroeconomists and political officers need rigorous, albeit realistic, quantitative models to forecast the future paths and dynamics of some variables of interest while being able to evaluate the effects of alternative scenarios. At the heart of all these models lies a standard macroeconomic module that, depending on the degree of sophistication and the research questions to be answered, represents how the economy works. However, the complete absence of a realistic monetary framework, along with the abstraction of banks and more generally of real–financial interactions—not only in dynamic stochastic general equilibrium (DSGE) models but also in central banks’ structural econometric models—made it impossible to detect the rising financial fragility that led to the Great Recession.
In this paper, we show how to address the missing links between the real and financial sectors within a post-Keynesian framework, presenting a quarterly stock-flow consistent (SFC) structural model of the Italian economy. We set up the accounting structure of the sectoral transactions, describing our “transaction matrix” and “balance sheet matrix,” starting from the appropriate sectoral data sources. We then “close” all sectoral financial accounts, describe portfolio choices, and define the buffer stocks for each class of assets and sector in the model. We describe our estimation strategy, present the main stochastic equations, and, finally, discuss the main channels of transmissions in our model.Download:Associated Program:Author(s):
Working Paper No. 942 | January 2020This paper emphasizes the need for understanding the interdependencies between the real and financial sides of the economy in macroeconomic models. While the real side of the economy is generally well explained in macroeconomic models, the financial side and its interaction with the real economy remains poorly understood. This paper makes an attempt to model the interdependencies between the real and financial sides of the economy in Denmark while adopting a stock-flow consistent approach. The model is estimated using Danish data for the period 1995–2016. The model is simulated to create a baseline scenario for the period 2017–30, against which the effects of two standard shocks (fiscal shocks and interest rate shocks) are analyzed. Overall, our model is able to replicate the stylized facts, as will be discussed. While the model structure is fairly simple due to different constraints, the use of the stock-flow approach makes it possible to explain several transmission mechanisms through which real economic behavior can affect the balance sheets, and at the same time capture the feedback effects from the balance sheets to the real economy. Finally, we discuss certain limitations of our model.Download:Associated Programs:Author(s):Mikael Randrup Byrialsen Hamid Raza
Working Paper No. 919 | January 2019While the literature on theoretical macroeconomic models adopting the stock-flow-consistent (SFC) approach is flourishing, few contributions cover the methodology for building a SFC empirical model for a whole country. Most contributions simply try to feed national accounting data into a theoretical model inspired by Wynne Godley and Marc Lavoie (2007), albeit with different degrees of complexity.
In this paper we argue instead that the structure of an empirical SFC model should start from a careful analysis of the specificities of a country’s sectoral balance sheets and flow of funds data, given the relevant research question to be addressed. We illustrate our arguments with examples for Greece, Italy, and Ecuador.
We also provide some suggestions on how to consistently use the financial and nonfinancial accounts of institutional sectors, showing the link between SFC accounting structures and national accounting rules.Download:Associated Program:Author(s):
Working Paper No. 750 | January 2013
The relevant economic literature frequently focuses on the impact of credit shocks on housing prices. The doctrine of the “New Consensus Macroeconomics” completely ignores bank credit. The “Great Recession,” however, has highlighted the significance of bank credit. The purpose of this contribution is to revisit this important macroeconomic variable. We propose to endogenize the volume of bank credit by paying special attention to those variables that are related to the real estate market, which can be considered key to the evolution of bank credit. Our theoretical hypothesis is tested by means of a sample of 15 Organisation for Economic Co-operation and Development (OECD) economies from 1970 to 2011. We apply the cointegration technique for the latter purpose, which permits the modeling of the long-run equilibrium relationship and the dynamics of the short run, along with an error-correction term.Download:Associated Program:Author(s):Philip Arestis Ana Rosa González
