This paper explores the effects of fiscal policy in the presence of a VAT evasion channel, and then compares and contrasts two regimes - the exogenous vs. optimal policy case. To this end, a dynamic general-equilibrium model, calibrated to Bulgarian data (1999-2014), is augmented with a...

This paper describes the lottery- and insurance-market equilibrium in an economy with non-convex market-sector employment and informal sector work. In contrast to Vasilev (2016a), the discrete-continuous labor supply decision in this paper is a sequential one, and instead of home production, we...

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...

In this paper we introduce reciprocity in labor relations and government sector to investigate how well the real wage rigidity that results out of that arrangement explains business cycle fluctuations in Bulgaria. The reciprocity mechanism described in this paper follows Danthine and Kurmann...

The purpose of this note is to explore the problem of a non-convex labor supply decision in an economy with unobservable e ort and incentive ("fair") wages a la Danthine and Kurmann (2004), and explicitly perform the aggregation presented there without a formal proof, and thus provide - starting...
