Submission of content to a digital object repository using a configurable workflow system
The prototype of a workflow system for the submission of content to a digital
object repository is here presented. It is based entirely on open-source
standard components and features a service-oriented architecture. The front-end
consists of Java Business Process Management (jBPM), Java Server Faces (JSF),
and Java Server Pages (JSP). A Fedora Repository and a mySQL data base
management system serve as a back-end. The communication between front-end and
back-end uses a SOAP minimal binding stub. We describe the design principles
and the construction of the prototype and discuss the possibilities and
limitations of work ow creation by administrators. The code of the prototype is
open-source and can be retrieved in the project escipub at

Asymmetric Labor Market Institutions in the EMU: Positive and Normative Implications
How do asymmetric labor market institutions affect the volatility of inflation and unemployment differentials in a currency union? What are the implications for monetary policy? To answer these questions, this paper sets up a DSGE currency union model with unemployment, hiring frictions and real wage rigidities. The model provides a rigorous but tractable framework for the analysis of the functioning of a currency union characterized by asymmetric labor market institutions. Positively, we find that inflation and unemployment differentials strongly depend on the underlying labor market structures. Moreover, asymmetries in labor market structures increase the volatility of both inflation and unemployment differentials. Normatively, we find that the optimal inflation target should give a higher weight to regions with more sclerotic labor markets but with more flexible real wages.Currency Union, labor market frictions, real wage rigidities, unemployment, sticky prices, inflation differentials, optimal monetary policy.
Asymmetric Labor Market Institutions in the EMU: positive and normative implications
How do labor market institutions affect the volatility and persistence of inflation and unemployment in a monetary union? What are the implications for monetary policy? This paper sets up a DSGE currency union model with unemployment, hiring frictions and real wage rigidities. The model provides a rigorous but tractable framework for the analysis of the functioning of a currency union characterized by asymmetric labor market institutions. Positively, we find that inflation and unemployment differentials depend strongly on the underlying labor market structure: the hiring friction lowers the persistence and increases the volatility of the inflation differential whereas real wage rigidities imply more persistence and variability in output and unemployment differentials. Normatively, we find that macroeconomic stabilization is easier when labor market frictions are high and real wage rigidities are low. This has important implications for optimal monetary policy: The optimal inflation target should give a higher weight to regions with more sclerotic labor markets and more flexible real wages.
