Drawing on a large database of publicly announced RD alliances.we track the evolution of RD networks in a large number of economic sectors over a long time period 1986 2009.Our main goal is to evaluate temporal and sectoral robustness of the main statistical properties of empirical RD networks....

We build an agent-based model to study how scal multipliers can change over the business cycle. Our approach considers the economy as a complex evolving system.In that,scal state-dependent multipliers are emergent disequilibrium phenomenon stemming from the interaction among an ecology of...
