a flow-duration curve (fdc) illustrates the relationship between the frequency and magnitude of streamflow. applications of fdc are of interest for many hydrological problems related to hydropower generation, river and reservoir sedimentation, water quality assessment, water-use assessment, water allocation and habitat suitability. this study was carried out in 11 selected watersheds with commo...

Electricity is indispensable for socio-economic developments. Its demand dramatically increasing in the domestic sector at an incredible pace despite distressing electricity deficiency most of world's developing economies like Pakistan.

Bir enerji kaynağı olarak fosil yakıt, Sanayi Devriminden itibaren üretimin en önemli unsurlarından biri olmuştur. Ancak yakıtların dünyanın her yerinde eşit bir şekilde dağılım göstermediği görülmektedir. Bu durum bazı ülkeleri ihracatçısı durumuna getirirken yakıt bulunmayan ise ithalatçı konuma getirmiştir. Yeterli kaynağına sahip olmayan ülkeler üretim miktarını ve toplumsal refah düzeyini ...

This paper studies how changes in energy input costs for U.S. manufacturers affect the relative welfare of manufacturing producers and consumers (i.e. incidence). In doing so, we develop a partial equilibrium methodology to estimate the incidence of input taxes that can simultaneously account for three determinants of incidence that are typically studied in isolation: incomplete pass-through of...

This paper studies how increases in energy input costs for production are split between consumers and producers via changes in product prices (i.e., pass-through). We show that in markets characterized by imperfect competition, marginal cost pass-through, a demand elasticity, and a price-cost markup are sufficient to characterize the relative change in welfare between producers and consumers du...

Journal: :Frontiers in sustainable cities 2021

Behavioral Economics has in recent years played a key role informing the design of non-price interventions aimed at promoting energy conservation behaviors residential housing. Some most influential contributions discipline an applied setting have centered around development norm-based interventions. The success that these had specific contexts presents opportunity to exploit them as tools for ...

مطالعه عوامل تأثیرگذار بر شدت انرژی در کشورهای منتخب عضو سازمان همکاری اقتصادی و توسعه (OECD)، علاوه بر ارائه راهکارهای استفاده بهینه­ از انرژی و تأمین امنیت بیشتر انرژی در این کشورها، به تدوین سیاست­گذاری­ها در جهت کاهش مصرف انرژی در کشورهای در حال توسعه نیز کمک شایان توجهی می­نماید. از این­رو، مطالعه حاضر، به بررسی تأثیر اندازه و کیفیت دولت به‌عنوان عامل­های موثر بر شدت انرژی در کشورهای منتخب...

نفت به‎عنوان بزرگ‎ترین منبع تأمین انرژی در جهان و به‎دلیل نقش آن در اقتصاد کشورهای تولید کننده، حائز اهمیت بسیار است. لذا شناخت پارامترهای مختلف تأثیر‎گذار بر بازار نفت برای این کشورها، ضروری به نظر می رسد. در این راستا، این تحقیق به پیش بینی قیمت به‎عنوان یک متغیر مهم از بازار جهانی نفت، با استفاده از روش شبکه های عصبی مصنوعی و نیز روش اقتصادسنجی ARIMA می پردازد. لازم به ذکر است که این پیش‎...

This paper studies how changes in energy input costs for U.S. manufacturers affect the relative welfare of manufacturing producers and consumers (i.e., incidence). In doing so, we develop a novel partial equilibrium methodology designed to estimate the incidence of input taxes. This method simultaneously accounts for three determinants of incidence that are typically studied in isolation: incom...
