Challet, Damien Solomon, Sorin Yaari, Gur 2008 We show that a simple model reproduces very closely the evolution of the GDP in constant dollars of many countries during the times of recession and recovery. A theoretical analysis illustrates how an optimal dynamical policy reduces both recession duration and severity, and increases the value of GDP at all times. We propose a criterion to distinguish a posteriori a dynamical policy from a static one. application/pdf https://folia.unifr.ch/global/documents/300607 https://folia.unifr.ch/documents/300607/files/challet_tst.pdf eng info:eu-repo/semantics/openAccess License undefined info:eu-repo/classification/udc/53 The therapy to shock therapy: optimal dynamical policies for transition economies http://purl.org/coar/resource_type/c_816b
