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...

This paper develops a four-sector equilibrium search and matching model with informal sector employment opportunities and educational choice. We show that underground activities reduce educational attainments if informal employment opportunities mainly are available for low-educated workers. A...

While examining the macroeconomic effects of increased government control of the informal sector, this paper develops a two-sector general equilibrium model featuring matching frictions, and heterogeneous workers in terms of moral. This facilitates an analysis of how wage setting and...

Some authors argue that informality is associated with distorted firm decisions and inefficiency. In this paper, I assess the quantitative effect of incomplete tax enforcement on aggregate output and productivity using a dynamic general equilibrium framework. I calibrate the model using data for...

We build a general equilibrium model in which both illegal immigration and the size of the informal sector are endogenously determined. In this framework, we show that indirect policy measures such as tax reduction and detection of informal activities can be used as substitutes for border...

The purpose of this paper is to explore the notion of economic informality and its application in the rural context of developing and transitional economies, applying Keith Hart's (1987) notion of informality as a 'remedial concept'. Some remedy is needed to make sense of the many 'palpable...

We consider an economy with two groups of individuals, rich and poor. A central authority can either directly redistribute income to the poor, or allow for some degree of informality in economic activities by not enforcing property rights. The optimal degree of informality depends upon the...

In recent years, it has been increasingly recognised that governments seeking to tackle undeclared work effectively should adopt a holistic approach. This seeks to coordinate strategy across the fields of labour, tax and social security law, and to use the full range of policy measures...
