Does Forced Solidarity Hamper Investment in Small and Micro Enterprises?
Grimm, Michael; Hartwig, Renate; Lay, Jann - Institute for the Study of Labor (IZA) - 2013
Sharing is a norm in many societies. We present a theoretical model on the trade-off between sharing and investment which we test on data from tailors in Burkina Faso. The empirical results support the idea that there are two behavioural patterns: entrepreneurs following an 'insurance regime'...

International Integration, Risk and the Welfare State
Andersen, Torben M. - Institute for the Study of Labor (IZA) - 2002
How does international integration affect the welfare state? Does it call for a leaner or an expanded welfare state? International integration may affect the distortions caused by welfare state activities but also the risks motivating social insurance mechanisms. This paper addresses these...

Determinants and Policy Simulation of Firms Cooperation in Innovation
Heshmati, Almas; Lenz-Cesar, Flávio - Institute for the Study of Labor (IZA) - 2013
This research introduces an agent-based simulation model representing the dynamic processes of cooperative R&D in the manufacturing sector of South Korea. Firms' behavior is defined according to empirical findings on the Korean Innovation Survey 2005 and captured in a multivariate probit...

Identification of Peer Effects through Social Networks
Bramoullé, Yann; Djebbari, Habiba; Fortin, Bernard - Institute for the Study of Labor (IZA) - 2007
-in-means model where each individual has his own specific reference group. Interactions are thus structured through a social network … exogenous effects are generally identified under network interaction, although identification may fail for some particular … structures. Monte Carlo simulations provide an analysis of the effects of some crucial characteristics of a network (i …

Simultaneous Search and Network Efficiency
Gautier, Pieter; Holzner, Christian - Institute for the Study of Labor (IZA) - 2011
When workers send applications to vacancies they create a network. Frictions arise because workers typically do not … friction affects network formation, while the second coordination friction affects network clearing. We show that those … that can arise and the number of matches on a given network. Equilibria that exhibit wage dispersion are inefficient in …

Efficient Coordination in Weakest-Link Games
Riedl, Arno; Rohde, Ingrid M.T.; Strobel, Martin - Institute for the Study of Labor (IZA) - 2011
Existing experimental research on behavior in weakest-link games shows overwhelmingly the inability of people to coordinate on the efficient equilibrium, especially in larger groups. We hypothesize that people are able to coordinate on efficient outcomes, provided they have sufficient freedom to...
