Effective sharing mechanisms of joint costs among beneficiaries of a project are a fundamental requirement for the sustainability of the project. Projects that are heterogeneous both in terms of the landscape of the area under development or the participants (users) lead to a more complicated set of allocation mechanisms than homogeneous projects. The analysis presented in this paper uses coope...

As the trend in electricity markets is strongly towards deregulation, new players, new rules and new behaviors will continue to emerge. Sellers will range from the traditional utility to the opportunistic broker, and endbuyers will have more possibilities to shop to get the best deal for their different energy needs. If a coalition of buyers can be worth, then it will be constituted. One of the...

We study optimal nonuniform pricing in a setting where a customer's demand at the start of a billing period contains a random variable whose realization becomes known by the end of the billing period. In this context, an optional calling plan is a tariff which the consumer must select based on his/her expectations about the random variable, whereas, under a tapered tariff, the consumer's choice...

Type two cuts, bad cuts and very bad cuts are introduced in [KL] for studying the relationship between Loeb measure and U-topology of a hyper nite time line in an !1-saturated nonstandard universe. The questions concerning the existence of those cuts are asked there. In this paper we answer, fully or partially, some of those questions by showing that: (1) type-two cuts exist, (2) the @1-isomorp...

This paper uses the gravity-model approach to deal with two issues related to economic integration. The first concern is to analyse the impact on FDI stocks of specific variables denoting the will to integrate, and their relative impact on exports. Variables considered include tariffs, non-tariff barriers and exchange rate variability. The results show that the widespread opinion – and theoreti...

This paper analyzes the relative significance of regional Economic Partnership Agreements (EPAs) in Asia-Pacific. The economy-wide impacts of tariff removals and reductions in non-tariff measures (NTMs) are estimated by using a Computable General Equilibrium (CGE) model of global trade. The Trans-Pacific Partnership (TPP) and the Regional Comprehensive Economic Partnership (RCEP) are shown to c...

The regulator of a natural monopoly that sets a two-part tariff and whose marginal cost is stochastic will generally want the price to vary less than marginal cost when the lump-sum charge in the tariff is fixed. A trade-off exists between efficient pricing and an optimal allocation of risk. Pricing at marginal cost is only optimal when the consumer’s marginal utility is independent of the pric...

In this paper we propose a layered framework for charging QoS-enhanced IP services with policy based configuration of its layers. As an example architecture we present our implementation Value Added IP Charging and Accounting Service (VIPCAS). We further concentrate on VIPCAS elements for policies and data exchange. As flexible data structure for exchange of accounting information, we propose t...
