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

The purpose of this paper is to describe the lottery- and insurance-market equilibrium in an economy with non-convex labor supply decision, unobservable effort, and efficiency wages of the no-shirking type a la Shapiro and Stiglitz (1984). The presence of indivisible labor creates a market...

The purpose of this paper is to explore the problem of non-convex labor supply decision in an economy with both discrete and continuous labor decisions. In contrast to the setup in Vasilev (2016a), here each household faces a sequential labor market choice - an indivisible labor supply choice in...

The purpose of this note is to explore the problem of non-convex labor supply decision in an economy with reciprocity in labor relations ("gift exchange") a la Danthine and Kurmann (2010), and explicitly perform the aggregation presented in Vasilev (2017) without a formal proof, and thus provide...

This paper utilizes a simple general-equilibrium model to analyse the long-run effects of Bulgaria’s 2007-08 corporate-personal income tax reforms. In particular, we consider the effect working through the firm’s capital structure, and argue that the new reforms incentivize firms to increase...

In this paper we provide a theoretical basis for the so-called” Armey curve,” the inverted U-shape relationship between the level of government purchases and GDP growth, named after Armey (1995). We use an otherwise standard Keynesian model, augmented with a quadratic relationship between...

The purpose of this paper is to explore the problem of non-convex labor supply decision in an economy where households feature consumption habits. We show how lotteries as in Rogerson (1988) can again be used to convexify consumption sets, and aggregate over individual preferences. The presence...

We utilize a standard endogenous-growth model with knowledge spillovers (the “k-K” model). We characterize the optimal Balanced Growth Path (BGP), and compare it to the path under market competition. In the presence of externalities, markets fail. One way to restore efficiency is to...

We utilize a relatively standard endogenous growth model with intermediaries and research and development (R&D). We augment the setup with government regulations to study the effect of regulations on aggregate allocations. The novelty is that we endogeneize the problem of the regulator, so the...

This note explores the problem of aggregation with non-convex labor supply decisions in an economy with both straight time and overtime. In contrast to Hansen and Sargent (1988), the paper models this as a sequential decision. Instead of changing from one to infinity, with a sequential...
