Nowadays one of the most important issues in our economy, both from economic and political view is the link between monetary policy and business cycle fluctuations. Amongst the shocks related to the supply side, the shock of oil price is the important factor that has affected the world economy since the 1970s. This paper examines the effects of monetary policy and oil price shocks on the busine...

In general, earthquake disasters in urban areas can hardly be handled by the operable disaster response teams of the affected region. An efficient and integrated disaster management could support their activities and help to limit human losses. Based on EQSIM, a damage estimation tool developed within the German Collaborative Research Centre 461: “Strong Earthquakes, a Challenge for Geosciences...

In a wireless storage system, having to communicate over a fading channel makes repair transmissions prone to physical layer errors. The first approach to combat fading is to utilize the existing optimal space-time codes. However, it was recently pointed out that such codes are in general too complex to decode when the number of helper nodes is bigger than the number of antennas at the newcomer...

The diversity-multiplexing tradeoff (DMT) for interference networks, such as the interference channel, the X channel, the Z interference channel and the Z channel, is analyzed. In particular, we investigate the impact of rate-splitting and channel knowledge at the transmitters. We also use the DMT of the Z channel and the Z interference channel to distill insights into the “loud neighbor” probl...

Search-based theories of the exchange process provide economists with a way of formalizing the microfoundations of monetary economics and to discuss a variety of issues in monetary theory and policy in a new light. Many questions that cannot even be formulated in more traditional monetary models can be profitably analyzed in these new models. In this essay, we propose to review recent developme...

The Economic and Monetary Union (EMU) implies a considerable change in monetary and fiscal policy design in the European Union. With the aid of a two-country version of the Alesina and Tabellini (1987) model, this paper provides a stylized analysis of monetary and fiscal policy interaction in the EMU. It is shown how macroeconomic outcomes are affected by common monetary and fiscal policies, an...

© 2013 ETRI Journal, Volume 35, Number 6, December 2013 http://dx.doi.org/10.4218/etrij.13.0213.0404 Dual-mode terminals (DMTs) equipped with cellular and WLAN interfaces have become popular in recent years. Users of DMTs can enjoy high-speed WLAN Internet access and wide area Internet access to cellular networks. However, a DMT may consume power inefficiently when discovering a WLAN with inher...
