for better guiding a system, senior managers should have accurate information. using data envelopment analysis (dea) help managers in this objective. thus, many investigations have been made in order to find the most productive scale size (mpss) for the evaluating decision making units (dmus). in this paper we consider this case where there exist subsets of input and output variables to be inte...

real exchange rate is one of the most important macroeconomic variables which affects various economic sectors. as the effect of real exchange rate variation is not equal in different sectors and due to importance of industrial development in economic development of country, this paper have investigated the effect of real exchange rate changes on  8 manufacturing subsectors over the period 1353...

The central purpose of the present research is to examine the ability of social value orientation (i.e., prosocial, individualistic, and competitive orientation), as measured with methods rooted in game theory (i.e., decomposed games), to predict real-life prosocial behavior. Consistent with hypotheses, results revealed that individual differences in social value orientation are predictive of v...

The sequential auction problem is commonplace in open, electronic marketplaces such as eBay. This problem occurs when a buyer faces a complex strategic problem in bidding across multiple auctions, each selling similar or essentially identical items and when the buyer would have a simple, truth-revealing strategy if there was but a single auction event. Our model allows for multiple, distinct go...

If we know the probabilities p1; : : : ; pn of diierent situations s1; : : : ; sn, then we can choose a decision Ai for which the expected beneet Ci = p1 ci1 + : : : + pn cin takes the largest possible value, where cij denotes the beneet of decision Ai in situation sj. In many real life situations, however, we do not know the exact values of the probabilities pj; we only know the intervals pj =...
