Germany's Short Time Compensation Program: macroeconom(etr)ic insight

Short Time Compensation [STC] was a key program in Germany to fight the crisis. However, STC is quite an old tool: in the past 100 years it has been used quite often and is very multifunctional. It stabilized employment in every kind of macroeconomic shock. After a brief look into the institutional and quantitative development of STC in Germany, this paper tries to answer the question whether STC prevents Schumpeterian creative destruction and structural change in economic downturns. With the help of a VAR-Model we can analyze interdependencies between the business cycle, STC and unemployment, finding evidence for a bridging function of STC. A closer look at the pro-cyclical average stoppage supports the thesis that most of the enterprises using STC are fundamentally economically healthy, that is, STC does not prevent structural change in downturns.Short Time Compensation, VAR, Paradox, structural change

Evaluating Connection Resilience for the Overlay Network Kademlia

Kademlia is a decentralized overlay network, up to now mainly used for highly scalable file sharing applications. Due to its distributed nature, it is free from single points of failure. Communication can happen over redundant network paths, which makes information distribution with Kademlia resilient against failing nodes and attacks. This makes it applicable to more scenarios than Internet file sharing. In this paper, we simulate Kademlia networks with varying parameters and analyze the number of node-disjoint paths in the network, and thereby the network connectivity. A high network connectivity is required for communication and system-wide adaptation even when some nodes or communication channels fail or get compromised by an attacker. With our results, we show the influence of these parameters on the connectivity and, therefore, the resilience against failing nodes and communication channels.Comment: 12 pages, 14 figures, accepted to ICDCS2017. arXiv admin note: substantial text overlap with arXiv:1605.0800
