ences in bank fees. We are able to show that bank fees are positively related to the&lt;br /&gt;
level of loan applicants' misperception of their skills (`noise'). We argue that in&lt;br /&gt;
countries with a higher level of `noise' banks tend to charge higher fees in order to&lt;br /&gt;
defend their bottom lines against the lower implied average quality of borrowers.&lt;br /&gt;
We further show that banks tend to charge higher fees when their creditworthiness&lt;br /&gt;
testing technology is of a lesser quality. Finally, we also illustrate how the results&lt;br /&gt;
about fees depend on the wealth level and wealth inequality in a given country.&lt;/p&gt;

costless testing by introducing credit bureau services. Unlike Broecker, we show&lt;br /&gt;
that there exists a symmetrical pure strategy Nash equilibrium in which all banks&lt;br /&gt;
fully use the credit bureau services. We show that this pure strategy equilibrium&lt;br /&gt;
can be interpreted as a competition softening (tacit collusion) outcome because&lt;br /&gt;
credit bureaus allow banks to coordinate on loan rates independent on marginal&lt;br /&gt;
costs. Compared to the existing models, our results are not based on the existence&lt;br /&gt;
of informational rents and thus they hold even under transactional banking. The&lt;br /&gt;
higher is the number of banks the less likely is the competition softening outcome&lt;br /&gt;
(the conditions for the competition softening equilibrium are less likely to be sat-&lt;br /&gt;
is¯ed) and thus there exists the optimal number of banks in the market under the&lt;br /&gt;
conditions of free entry.&lt;/p&gt;

The test utilizes the relationship&lt;br&gt; between CVaR and dual second-order stochastic dominance, and contrary to tests in Post&lt;br&gt; [14] and Kuosmanen [7], our test detects a dominating portfolio which is SSD efficient. We&lt;br&gt; derive also a necessary condition for SSD efficiency using convexity property of CVaR to&lt;br&gt; speed up the computation. The efficiency measure represents a distance between the tested&lt;br&gt; portfolio and its least risky dominating SSD efficient portfolio. We show that this measure&lt;br&gt; is consistent with the second-order stochastic dominance relation. We find out that this&lt;br&gt; measure is convex and we use this result to describe the set of SSD efficient portfolios.&lt;br&gt; Finally, we illustrate our results on a numerical example.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Chovanec, P.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">New criteria for stochastic DEA</style></title><secondary-title><style face="normal" font="default" size="100%">Proceedings of the 23rd International Conference Mathematical Methods in Economics 2005</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2005</style></year></dates><publisher><style face="normal" font="default" size="100%">Gaudeamus</style></publisher><pub-location><style face="normal" font="default" size="100%">Hradec Kralove, Czech Republic</style></pub-location><pages><style face="normal" font="default" size="100%">164-170</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;By its nature, Data Envelopment Analysis (DEA) leaves no room for uncertainty in data such as measurement errors.

This institution has also to pay every month for subsidized workplaces otherwise it has to compensate the worker for releasing her/him. The model uses a &amp;quot;socially critical&amp;quot; rate of unemployment, the rate which should be reduced at all costs. This problem can be seen as the problem of multistage stochastic programming because the compensation of the worker can be cheaper than paying the subsidy every month. The model is demonstrated on the Most region (the Czech region facing the worst unemployment situation), and the four-stage model is solved using scenario-based method in the GAMS language on NEOS system.&lt;/p&gt;
