Mehr Sicherheit im Umgang mit Trachealkanülen - Pflegende, die Patienten mit einer Trachealkanüle betreuen, müssen den Kanülenwechsel sicher beherrschen. Denn bei Komplikationen kann das Warten auf den Arzt katastrophale Folgen haben. Daher muss der Umgang mit den Kanülen zur Routine werden.     

Problems in the creation of an optimal currency zone in the Commonwealth of Independent States

The paper evaluates the features of the Commonwealth of Independent States as a regional economic union of states on the territory of the former Soviet Union. It examines the most noticeable conceptual approaches to the definition of strategy, the directions of CIS development, and the monetary and credit mechanisms of interactions among member states, as well as the feasibility of CIS transformation into an efficient economic union of states.     

Role of large companies in Russia’s oil and gas complex

The purpose of this article is to reconsider the interaction between major oil and gas companies and the state, which is especially important for modern Russia given its current conditions. General theoretical approaches are presented, as well as calculations of price and financial indicators reflecting the performance of these companies.     

Not all trade restrictions are created equally

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers. However, it is typical in many of these models to use iceberg transport costs as a general form of trade barriers that can be interchangeable with ad valorem tariffs. I show that this is not always an appropriate conclusion. Specifically, I illustrate that profit for an exporter is more elastic in response to tariffs than iceberg transport costs, which affects the entry/exit decision of firms. This has implications for welfare analysis and empirical specifications.     

Should multivariate early warning systems for banking crises pool across regions?

Most extant work on prediction of banking crises has utilised global samples, which are in turn dominated by observations from middle-income countries, and rely on a single estimator. However, economic and financial structures as well as the pattern of shocks may differ substantially across regions, while a range of specifications is desirable to check robustness. Accordingly, in this paper we test the implicit pooling assumption in earlier multivariate work on Early Warning Systems using both logit and binary recursive tree specifications separately for crises in Asia and Latin America, as well as the pooled sample. Results suggest markedly different crisis determinants across regions, implying global samples are inappropriate.
