Competition and Market Dynamics on the Russian Deposits Market
In the early transition era in Russia entry barriers for commercial banks were about absent. It resulted in the mushrooming of hundreds of small, poorly-endowed and inexperienced banks. In this paper we address the question whether the claimed benefits of low entry barriers - competition and market dynamics - have resulted. We use a sample of commercial saving banks for the 1994-97 period. We conclude that there were important mobility barriers and that the removal of entry barriers did not lead to intensified competition
Fuelling conditions at staging sites can mitigate Arctic warming effects in a migratory bird
Under climate warming, migratory birds should align reproduction dates with advancing plant and arthropod phenology. To arrive on the breeding grounds earlier, migrants may speed up spring migration by curtailing the time spent en route, possibly at the cost of decreased survival rates. Based on a decades-long series of observations along an entire flyway, we show that when refuelling time is limited, variation in food abundance in the spring staging area affects fitness. Bar-tailed godwits migrating from West Africa to the Siberian Arctic reduce refuelling time at their European staging site and thus maintain a close match between breeding and tundra phenology. Annual survival probability decreases with shorter refuelling times, but correlates positively with refuelling rate, which in turn is correlated with food abundance in the staging area. This chain of effects implies that conditions in the temperate zone determine the ability of godwits to cope with climate-related changes in the Arctic
