We derive an expression relating the change in instantaneous utility to the growth of net (genuine) saving in an economy with multiple stocks and externalities that maximizes welfare in the utilitarian sense. This result is then shown to hold for decentralized competitive efficient economies as well, to yield an extension of the Hartwick rule: instantaneous utility is non-declining along a deve...

As the load on distribution networks grows, system operators and planners are constantly challenged with issue of voltage regulation or enhancing quality supply to customers at end lengthy lines. This paper presents optimum determination series capacitor units in a maximize energy-saving enhance levels. Interestingly, capacitors can capability transmission lines, reduce line losses, performance...

We develop a tractable two-country overlapping-generations model and show that cross-country differences in financial development can explain three recent empirical patterns of international capital flows: Financial capital flows from relatively poor to relatively rich countries, while foreign direct investment flows in the opposite direction; net capital flows go from poor to rich countries; d...

Neutrophils, the most abundant human immune cells, are rapidly recruited to sites of infection, where they fulfill their life-saving antimicrobial functions. While traditionally regarded as short-lived phagocytes, recent findings on long-term survival, neutrophil extracellular trap (NET) formation, heterogeneity and plasticity, suppressive functions, and tissue injury have expanded our understa...

Porter hypothesis states that environmental regulation may lead to winwin opportunities, that is, improve the productivity and reduce the undesirable output simultaneously. Based on directional distance function, this paper proposes a novel dynamic activity analysis model to forecast the possibilities of win-win development in Chinese industry between 2011 and 2050. The consistent bootstrap est...

The presented work contains the comparison of a different photovoltaic system approach, in terms monthly energy production profiles, with detailed user needs profiles. Two types investors were taken into account—a company where yearly consumption exceeded 50 MWh and standard household was around 6 MWh. Moreover, two scenarios considered; first one focused on maximization during year by choosing...

Profit maximization (PM) is to select a subset of users as seeds for viral marketing in online social networks, which balances between the cost and profit from influence spread. We extend PM that under general strategy, form continuous (CPM-MS) problem, whose domain on integer lattices. The objective function our CPM-MS dr-submodular, but non-monotone. It typical case unconstrained dr-submodula...

Many studies have shown that the careful planning of construction logistics can result in significant saving. However, despite attempts to improve the logistics of construction materials, the purchase, delivery, storage and movement of materials are still conducted in a rather unstructured manner. In this paper, construction logistics are modeled and analyzed using Petri Net (PN) techniques. Th...

In this paper we present an analysis of investment incentives for network infrastructure owners under two different pricing strategies: congestion based negative externality pricing and the prevalent flat rate pricing. The challenge in a networked environment is to increase capacity of the different components of the network appropriately based on demand for these different components. We devel...

I distinguish the impacts of input spillovers and imperfect appropriability of the revenue generated by cost-saving innovation in a racing model. Comparativestatic relationships with respect to the level of spillovers depend on the levels of post-innovation payoffs; comparative-static relationships with respect to the degree of appropriability depend on changes in the levels of post-innovation ...
