The paper deals with rent-seeking behaviour among agents competing for future shares of a common renewable natural resource. Rent-seeking might become profitable when the agents expect that the distribution of the natural resource in future periods will be dependent on the agents’ extraction of the resource in the past, even though high exploitation might reduce the stock that future individual...

there are many approaches in economic literature for investigation of firm performance. in general, those theories very useful for investigation the nature and role of competitive advantage. resource based view, dynamic capability, entrepreneurial theory, neoclassic theory, industrial organization approach are some of those theories. todays, banks try to attract customers through various new me...

In this paper, we propose a cross-lingual convolutional neural network (CNN) model that is based on word and phrase embeddings learned from unlabeled data in two languages and dependency grammar. Compared to traditional machine translation (MT) based methods for cross lingual sentence modeling, our model is much simpler and does not need parallel corpora or language specific features. We only u...

on one hand, oil is the greatest energy resource in the world and, on the other hand, because of the role of oil revenue in the economic of oil producer countries, such as iran,it is vital for these countries. so it is necessary to recognize different affective parameters on oil market for these countries. in this research, we try to forecast oil price as an important variable in world wide oil...

ion: services and quality of service. In the simplest case, a Dependency Description simply lists the other resources a resource depends on. This means that the dependencies refer to specific software or hardware components. For greater flexibility, it is possible to specify the abstract service types a resource provides. For example, the Dependency Description of an application that displays i...

Modern forms of energy are an important vehicle towards poverty alleviation in rural areas of developing countries. Most developing countries’ households heavily rely on wood fuel which impact their health and social–economic status. To ease such a dependency, other modern forms of energy, namely electricity, need to be provided. However, the quality of the electricity service, namely reliabili...

Robust portfolio optimization has been developed to resolve the high sensitivity to inputs of the Markowitz mean-variance model. Although much effort has been put into forming robust portfolios, there have not been many attempts to analyze the characteristics of portfolios formed from robust optimization. We investigate the behavior of robust portfolios by analytically describing how robustness...

 Given that improvement in efficiency is a major resource to economic development, this can be applied to each domestic sector of an economy. The objective of this paper is to measure technical efficiency of the Iranian Post Company across the country’s provinces using data envelopment analysis (DEA). The ranking of technical efficiency has been calculated by using collected data on post offi...
