the mechanism of public-private partnership (ppp) has been used in different countries. many countries have enacted special laws to regulate ppps. in iran, ppp as such has been briefly mentioned in the fifth five year development act and more details of ppps were provided in the yearly budget acts of 1391 and 1392 (2012 and 2013). in the budget act of 1393 (2014) the detailed provisions regardi...

The risk-sensitive foraging theory formulated in terms of the (daily) energy budget rule has been influential in behavioural ecology as well as other disciplines. Predicting risk-aversion on positive budgets and risk-proneness on negative budgets, however, the budget rule has recently been challenged both empirically and theoretically. In this paper, we critically review these challenges as wel...

In a combinatorial auction k different items are sold to n bidders, where the objective of the seller is to maximize the revenue. The main difficulty to find an optimal allocation is due to the fact that the valuation function of each bidder for bundles of items is not necessarily an additive function over the items. An auction with budget constraints is a common special case where bidders gene...

We study the problem of allocating items to two agents with arbitrary valuation functions. Instead of actual money, we use sequential auctions with “scrip money”, i.e. money that has no value outside the auction. By considering such scrip auctions as a special case of more general bidding games, we show that there exists a natural pure subgame perfect Nash equilibrium (PSPE) with the following ...

As for the East Asian countries, the total amount of government debt in Korea has risen sharply over the following several years in the wake of the Asian financial crisis. The purpose of this paper is to assess whether the current levels of government debt are sustainable for a severely attacked country, namely, Korea. Under the intertemporal budget constraint model, the study tests for fiscal ...
