Unraveling firms : demand, productivity and markups heterogeneity
Forlani, Emanuele; Martin, Ralf; Mion, Giordano; Muls, … - 2016 - First draft: 16th June 2015. This draft: January 15, 2016
We develop a new econometric framework that simultaneously allows recovering heterogeneity in demand, TFP and markups across firms while leaving the correlation among the three unrestricted. We do this by systematically exploiting assumptions that are implicit in previous firm-level productivity...

Firm size and diversification : asymmetric multiproduct firms under Cournot competition
Grossmann, Volker - 2003
A positive relationship between firm size and product diversification is a long-standing stylized fact. However, so far there is no appropriate theoretical model to explain the underlying forces of this observation. This paper analyzes an oligopoly model with asymmetric multiproduct frms, which...

Efficient firm dynamics in a frictional labor market
Kaas, Leo; Kircher, Philipp - 2011
The introduction of firm size into labor search models raises the question how wages are set when average and marginal product differ. We develop and analyze an alternative to the existing bargaining framework: Firms compete for labor by publicly posting long-term contracts. In such a...

What are the pro-competitive consequences of trade in frictional labor markets? This paper develops and estimates a dynamic general equilibrium trade model to show that the interplay between endogenously variable markups in product markets and frictions in labor markets has important...

Competition and relationship lending : friends or foes?
Presbitero, Andrea; Zazzaro, Alberto - 2010
Recent empirical findings by Elsas (2005) and Degryse and Ongena (2007) document a U-shaped effect of market concentration on relationship lending which cannot be easily accommodated by the investment and strategic theories of relationship lending. In this paper, we suggest that this...

Job mobility and the gender wage gap in Italy
Del Bono, Emilia (contributor); Vuri, Daniela (contributor) - 2008
This paper investigates the way in which job mobility contributes to the emergence of a gender wage gap in the Italian labour market. We show that men experience higher wage growth than women during the first 10 years of their career, and that this difference is particularly large when workers...

Absenteeism, unemployment and employment protection legislation : evidence from Italy
Scoppa, Vincenzo; Vuri, Daniela - 2013
Efficiency wages theories argue that the threat of firing, coupled with a high unemployment rate, is a mechanism that discourages employee shirking in asymmetric information contexts. Our empirical analysis aims to verify the role of unemployment as a worker discipline device, considering the...

Preponderance of evidence
Demougin, Dominique; Fluet, Claude - 2002
This paper analyzes the incentive properties of the standard and burden of proof for a finding of negligence, when evidence is imperfect and rests with the parties. We show that the preponderance of evidence' standard provides maximal incentives to exert care. This holds even though litigants...
