The 2009 Conference of the Ensuring Economic and Employment Stability (EES) network is jointly organized by CREI and the Kiel Institute for the World Economy, and will take place in Barcelona from October 30th to October 31st. The topics covered at the Conference are (i) micro-foundation of wage rigidity, (ii) new evidence on fluctuations of worker flows and wages, (iii) alternative mechanisms to the matching concept and the role of heterogeneity, and (iv) driving forces of business cycle fluctuations. The first conference of the EES network, held on October 30-31, 2009, at the campus of the Universitat Pompeu Fabra in Barcelona, concluded successfully. The conference was co-organized by CREI and Kiel Institute for the World Economy. Held under the theme “macroeconomic fluctuations and the labor market,” the conference brought together leading researchers in the field to present and discuss cutting edge research on the workings of the labor market and how it propagates macroeconomic shocks. The conference was split into three sessions: (i) heterogeneity and alternatives to the search and matching theory (chaired by Per Krusell), (ii) the role of job separations (chaired by Jordi Galí), and (iii) wage rigidity (chaired by Chris Pissarides).
