The paper introduces a portfolio-based Keynesian dynamic stochastic general disequilibrium model. It is an endogenous phase-switching macroeconomic model of risky investment where the rational expectation is applied in the financial market with three financial instruments of stocks, credits, and...

This 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...

This paper considers a plan proposed by Warren Buffett, in which importers would be required to obtain certificates proportional to the amount of non-oil goods (and possibly also services) they brought into the country. These certificates would be granted to firms that exported goods. Exporting...

DSGE models have recently become one of the most frequently used tools in policy analysis. Nevertheless, their forecasting proprieties are still unexplored. In this article we address this problem by examining the quality of forecasts from a small size DSGE model, a trivariate VAR model and the...

Despite being arguably one of the most active areas of research in heterodox macroeconomics, the study of the dynamic properties of stock-flow consistent (SFC) growth models of financially sophisticated economies is still in its early stages. This paper attempts to offer a contribution to this...

This paper sets out a rigorous basis for the integration of Keynes-Kaleckian macroeconomics (with constant or increasing returns to labor, multipliers, mark-up pricing, etc.) with a model of the financial system (comprising banks, loans, credit money, equities, etc.), together with a model of...

We explore the effects of forward guidance at the zero lower bound when there is uncertainty over the lift-off date arising from: (i) the imperfect credibility of time-inconsistent forward-guidance promises; (ii) incomplete communication. We use a simple New Keynesian model to demonstrate that a...

Using Gretl, I apply ARMA, Vector ARMA, VAR, state-space model with a Kalman filter, transfer-function and intervention models, unit root tests, cointegration test, volatility models (ARCH, GARCH, ARCH-M, GARCH-M, Taylor-Schwert GARCH, GJR, TARCH, NARCH, APARCH, EGARCH) to analyze quarterly time...

This paper uses a multi-region, forward-looking, DSGE model to estimate the macroeconomic impact of a tax reform that replaces a corporate income tax (CIT) with a destination-based cash-flow tax (DBCFT). Two key channels are at play. The first channel is the shift from an income tax to a...

This paper presents a new solution method for dynamic equilibrium models. The proposed method approximates the solution by polynomials that zero the residual function and its derivatives at a given point x0. It is essentially a projection-type algorithm, but is significantly faster than standard...
