In search of stars : network formation among heterogeneous agents
Goeree, Jacob K. (contributor); Riedl, Arnold (contributor);  … - 2005
This paper reports the results of a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the basic Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by … network has a "star" structure. We find that with homogeneous agents, equilibrium predictions fail completely. In contrast …

Simultaneous search and network efficiency
Gautier, Pieter; Holzner, Christian - 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 …

Matching through search channels
Carrillo-Tudela, Carlos; Kaas, Leo; Lochner, Benjamin - 2023
Firms and workers predominately match via job postings, networks of personal contacts or the public employment agency, all of which help to ameliorate labor market frictions. In this paper we investigate the extent to which these search channels have differential effects on labor market...

When is high turnover cheaper? : a simple model of cost tradeoffs in a long‐ distance truckload motor carrier, with empirical evidence and policy implications
Burks, Stephen V.; Kildegaard, Arne; Miller, Jason; … - 2023
The U.S. trucking industry has been calling out a shortage of truck drivers for nearly forty years, since soon after its economic deregulation in 1980. Burks and Monaco (2019) provided evidence that the overall truck driver labor market works about as well as any blue collar labor market, and...

Key links in network interactions: assessing route-specific travel restrictions in China during the COVID-19 pandemic
Chen, Xi; Qiu, Yun; Shi, Wei; Yu, Pei - 2022
We consider a model of network interactions where the outcome of a unit depends on the outcomes of the connected units …. We determine the key network link, i.e., the network link whose removal results in the largest reduction in the aggregate … outcomes, and provide a measure that quantifies the contribution of a network link to the aggregate outcomes, which complements …

Key players in economic development
Amarasinghe, Ashani; Hodler, Roland; Raschky, Paul A.; … - 2020
This paper analyzes the role of networks in the spatial diffusion of local economic shocks in Africa. We show that road and ethnic connectivity are particularly important factors for diffusing economic spillovers over longer distances. We then determine the key players, i.e., which districts are...
