Infinitesimal Perturbation Analysis (IPA) is a method for computing a sample path derivative with respect to an input parameter in a discrete event simulation. The IPA algorithm is based on the fact that for certain parameters and any realization of a simulation, the change in parameter can be...

The technique of perturbation analysis has recently been introduced as an efficient way to compute parameter sensitivities for discrete event systems. Thus far, the statistical properties of perturbation analysis have been validated mainly through experiments. This paper considers, for an M/G/1...

We present a model which enables efficient analysis of certain types of closed queueing networks with blocking due to limited buffer spaces. The networks analyzed are those in which the limited buffers occur in tandem subnetworks. A new model, with variable buffer-size, is introduced as a...

Muchos problemas del desarrollo van más allá de las fronteras nacionales y tienen un carácter regional e incluso global. El reconocimiento de estos retos, los cuales van de la transmisión de enfermedades entre fronteras hasta la dispersión de inestabilidad financiera global, ha llevado a...

Heightened uncertainty since the onset of the Great Recession has materially increased saving rates, contributing to lower consumption and GDP growth. Consistent with a model of precautionary savings in the face of uncertainty, the paper finds for a panel of advanced economies that greater labor...

From its early post-war catch-up phase, Germany's formidable export engine has been its consistent driver of growth. But Germany has almost equally consistently run current account surpluses. Exports have powered the dynamic phases and helped emerge from stagnation. Volatile external demand, in...

The euro areaâ??s political contract requires member nations to rely principally on their own resources when confronted with severe economic distress. Since monetary policy is the same for all, national fiscal austerity is the default response to counter national fiscal stress. Moreover, the...
