Design of a virtual combine harvester
Maertens, K; De Baerdemaeker, J - In: Mathematics and Computers in Simulation (MATCOM) 65 (2004) 1, pp. 49-57
Separation processes in agricultural machinery are typically non-linear, complex and uncertain. On-line measurements of input and output data are not available. Therefore, black-box modelling is not applicable and other techniques to describe the system must be used. In this paper, a dynamic...

Bilateral Information Sharing in Oligopoly
Currarini, Sergio; Feri, Francesco - Dipartimento di Economia, Università Ca' Foscari Venezia - 2007
We study the problem of information sharing in oligopoly, when sharing decisions are taken before the realization of private signals. Using the general model developed by Raith (1996), we show that if firms are allowed to make bilateral exclusive sharing agreements, then some degree of...

Business networks, production chains, and productivity: A theory of input-output architecture
Oberfield, Ezra - 2011
This paper studies an analytically tractable model of the formation and evolution of chains of production. Over time, entrepreneurs accumulate techniques to produce their good using goods produced by other entrepreneurs and labor as inputs. The value of a technique depends on both the...

Games on networks: Direct complements and indirect substitutes
Currarini, Sergio; Fumagalli, Elena; Panebianco, Fabrizio - 2013
Many types of economic and social activities involve significant behavioral complementarities (peer effects) with neighbors in the social network. The same activities often exert externalities that cumulate in stocks affecting agents' welfare and incentives. For instance, smoking is subject to...

From Tradition to Modernity: Economic Growth in a Small World
Lindner, Ines; Strulik, Holger - 2011
This paper introduces the Small World model (Watts and Strogatz, Nature, 1998) into the theory of economic growth and investigates how increasing economic integration affects firm size and effciency, norm enforcement, and aggregate economic performance. When economic integration is low and local...

Coordination in Evolving Networks with Endogenous Decay
Feri, Francesco; Meléndez-Jiménez, Miguel A. - 2009
This paper studies an evolutionary model of network formation with endogenous decay, in which agents benefit both from direct and indirect connections. In addition to forming (costly) links, agents choose actions for a coordination game that determines the level of decay of each link. We address...
