the role of distance as border effects between trade partners has been created challengeable discussions in gravity model literature for international economists and lead to different theoretical aspects for measuring and modeling of it in recent years. moreover, the necessity of non-linear method for estimation of gravity model has been perfectly agreed. the importance of this study is the est...

in this paper, asymmetric effects of exchange rate fluctuation (according to positive and negative shocks) on real output were investigated. in the meantime, the study of behaviour of real output growth in iran’s economy over the period 1338-1386 was done. in specification of the output growth equation, in spite of considering positive and negative shocks of exchange rate, the effects of other ...

For the model of so-called coherent computing recently proposed by Yamamoto et al. [Y. Yamamoto et al., New Gen. Comput. 30 (2012) 327-355], a theoretical analysis of the success probability is given. Although it was claimed as their prospect that the Ising spin configuration problem would be efficiently solvable in the model, here it is shown that the probability of finding a desired spin conf...

Currently, the Thailand government is promoting biofuel, especially producer of biodiesel. Starting from 2015, Ministry Energy has determined that palm oil remaining domestic consumption 14 million liters per day in 2036. Forecasting biodiesel prices are most important since price volatility affects renewable energy future. This paper presents with time series decomposition method. The source d...

Acute internal carotid artery (ICA) occlusionmay result in severe disability or death. Revascularization by carotid artery stenting after treatment with intravenous (iv) recombinant tissue-type plasminogen activator (rt-PA) has been documented. However, there are few reports on emergency carotid endarterectomy (CEA) within 24 hours after the iv administration of rt-PA. We treated a 58-year-old ...

the economy's dependence on oil revenues and derivatives of these products make the country's economy heavily influenced by the volatility and instability of the pricing of these products. therefore, it seems necessary to develop non-oil exports. this paper examines the causality relation and the effect of foreign direct investment, economic openness and real exchange rate on non-oil ...

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...
