Tax Evasion, Investment Shocks, and the Consumption Puzzle: A DSGE Analysis with Financial Frictions

Recent studies identify Marginal Efficiency of Investment (MEI) shocks as important drivers of the business cycle. However, Dynamic Stochastic General Equilibrium (DSGE) models struggle to explain macroeconomic comovements between consumption and the key real variables after a MEI shock. Moreover, engaging in tax evasion practices is often an answer to financial constraints, which have been recognized as important determinants of cyclical fluctuations as well. We use a medium-scale New Keynesian DSGE model, that combines tax evasion with financial frictions, to simulate a MEI shock. We show that entrepreneurial tax evasion can solve the comovement problem to a fair extent.
