While in less developed and in transition economies microlending has become an efficient instrument for providing small and micro businesses with the necessary financial means, in industrialized countries, with highly developed banking systems, the existence and size of an uncovered demand for...

We investigate if pluralistic consumption styles (like "frugality", or "indulgence in luxury") can be identified and are correlated with different terminal values and if values and consumption styles prove to be stable or can be changed by drastic events. The results of two polls (before and...

Die Europa-Universität Viadrina versteht sich als Brückenuniversität zwischen Polen und Deutschland; seit ihrer Gründung studieren dort polnische und deutsche Studierende gemeinsam. Wie gehen die Studierenden miteinander um, und welche Bedeutung hat die kulturelle Offenheit für die...

We analyze the incentive mechanism of individual micro-lending contracts and we compare its key factors with those of joint-liability loan contracts. Using our data set, we firstly show that in the individual contract there are three elements, the demand for non-conventional collateral, a...

In Dictator Game experiments where the information status of the recipient varies we find that a certain type of donator tends to reduce his offer when the recipient has incomplete information about the pie size. This result provides new evidence on those approaches on altruism, which assume...

How can a principal (an agent) ensure that an agent (a principal) will work (pay up), if payment (work) precedes work (payment)? When a banknote is torn in two, each part is by itself worthless. A principal can pre-commit to payment-on-delivery, by tearing a banknote and giving the agent the...

In Dictator Game experiments where the information status of the participants varies we find that a certain type of proposer tends to reduce his offers when the recipient has incomplete information about the pie size. We also find that a certain type of recipient tends to reject too small offers...

We empirically examine the efficacy of various incentives of microlending contracts such as joint-liability or group access to future loans. We find that joint liability induces a group formation of low risk borrowers. Furthermore, the incentive system leads to peer measures between the...

For many people "solidarity" has become a meaningless word used in slogans - too often used without leading to any economic consequences. We show in this paper conditions under which solidarity can be a powerful instrument. In a solidary action, an individual in a group contributes to a series...

Models to the issue of altruism which rely on externalities of well-being are rarely used explicitly. In this paper we compare such utility-based approaches with the standard approach on altruism which is based on externalities of income. Testable differences of both types of models are derived...
