How does economic activity outside of government control-informality-affect the conduct of fiscal and monetary policy? I study this question in a New Keynesian, small open economy model. The model is assumed to feature informality in both goods and labor markets. A non-traded sector produces a...

Macroeconomic models that omit the shadow economy systematically mis-forecast and mis-measure the effect of fiscal –in particular tax– policy on economic activity and tax revenue. We add an informal sector to the Bank of Greece DSGE model and use the actual package of fiscal consolidation...

We discuss the implications of informality on growth and fiscal policy by considering an informal sector based on low tech firms, in an open economy model of endogenous growth, where labour supply is elastic and increasing returns arise from public spending. We allow for both labour and capital...

We show that, in many countries, tax compliance is volatile and markedly responds to fiscal policy. To explore the consequence of this novel stylized fact, we build a model of sovereign debt with limited commitment and imperfect tax enforcement. Fiscal policy persistently affects the size of the...

This paper investigates the role of informality in affecting the magnitude of the fiscal multiplier in a panel of 141 countries, using the local projections method. We find a strong negative relationship between the degree of informality and the size of the fiscal multiplier. This result holds...

This paper investigates the effects of fiscal impulses on macroeconomic variables within a New-Keynesian DSGE framework featuring an informal economy that allows for the examination of the effectiveness of automatic stabilizers in stimulating some selected sub-Saharan African (SSA) economies...

The government influences the equilibrium size of hidden activity. Higher taxes give an incentive to evade. The provision of public services, social transfers and public employment may have offsetting effects on the underground economy. The budget constraint makes the relation between the shadow...

In this paper, I argue that international policy coordination requires to include both monetary as well as fiscal policy because both sides include policy instruments that allow the strategic manipulation of the country's terms of trade. Hence, the coordination of one part of national...

Should the government run fiscal deficits in response to an adverse external shock that warrants transfer of resources from production of non-traded to traded goods? This paper considers normative fiscal policy implications of sectoral adjustment costs in a two-sector model with overlapping...
