This paper is a first attempt to provide a quantitative evaluation of the welfare gains resulting from the introduction of flat income taxation in Bulgaria in 2008. Using a calibrated micro-founded endogenous growth model with physical and human capital accumulation to Bulgarian data, a...

This paper provides a quantitative evaluation of the welfare effect of the introduction of proportional taxation in Bulgaria in 2008, an effect that operates through the grey economy channel. Using a general-equilibrium model, augmented with informal sector, a computational experiment is...

Motivated by the highly-unionized public sectors, the high public shares in total employment, and the public-sector wage premia observed in Europe, this paper examines the importance of public-sector unions for macroeconomic theory. The model generates cyclical behavior in hours and wages that...

This paper shows a standard RBC model, when augmented with a VAT evasion channel, where evasion depends on the consumption tax rate, can produce a hump-shaped consumption Laffer curve. Furthermore, when the evasion channel is turned off , the hump in the Laff er curve disappears, resulting in a...

The purpose of this note is to explore the problem of non-convex labor supply decision in an economy with imperfect observability of work e ffort, and the need to use e fficiency wages to prevent shirking as in Shapiro and Stiglitz (1984). In addition, the paper and explicitly performs the...

In this paper we investigate the quantitative importance of e fficiency wages in explaining fluctuations in Bulgarian labor markets. This is done by augmenting an otherwise standard real business cycle model a la Long and Plosser (1983) with unobservable workers e ort by employers and wage...

This paper explores the problem of non-convex labor supply decisions in an economy with both private and public sector jobs. To this end, Hansen (1985) and Rogerson's (1988) indivisible-hours framework is extended to an environment featuring a double discrete labor choice. The novelty of the...
