This paper builds a two-country (North, South), two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good is produced with a clean and a dirty input. A temporary Northern policy combining clean research subsidies and a trade tax can ensure sustainable growth but Northern ...
This paper builds a two-country, two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good generates more or less emissions depending on its relative use of a clean and a dirty input. I show that a unilateral policy combining clean research subsidies and a trade tax can e...
This paper uses both theory and empirical work to examine the effect of environmental regulations on trade flows. We develop a simple economic model to demonstrate how unobserved heterogeneity, endogeneity and aggregation issues bias measurements of the relationship between regulatory costs and trade. We estimate a reduced-form of the model using data on U.S. regulations and net trade flows amo...
Insulin receptor substrate 1 (IRS-1) is a major substrate of insulin, insulin-like growth factors, and cytokine signaling and plays an important role in mediating apoptosis, cell differentiation, and cell transformation. We found that IRS-1 is constitutively activated in a variety of solid tumors, including breast cancers, leiomyomas, Wilms' tumors, rhabdomyosarcomas, liposarcomas, leiomyosarco...
چکیده: موضوع توزیع درآمد عواملی و تاثیر آن بر نابرابری، در ادبیات کلاسیک اقتصادی از ارکان اصلی مطالعات بوده است. اما با تکیه اقتصاددانان قرن بیستم اعم از کینزی ها و نئوکلاسیک ها بر ثبات سهم عوامل این بحث از رونق می افتد. در نهایت پساکینزی ها ضمن قبول امکان تغییر در سهم عوامل، ارتباط توزیع درآمد شخصی و عواملی را رد می کنند. نوشته ی حاضر با احتساب کارگران غیر ماهر در معادلات بازار کار، با رد نظ...
در ادبیات مدرن تجارت بین الملل، کارکرد نهادی و اتخاذ قوانین و مقررات مناسب و کارا از منظر تجارت از علل اساسی توسعه اقتصادی کشورها محسوب می گردد. مؤلفه های انباشت سرمایهگذاری مستقیم خارجی و صادرات را میتوان از مؤلفه های کلیدی عرصه تجارت برشمرد که بسیاری از کشورها توانستهاند با بهرهمندی از آنها به رشد و توسعه اقتصادی دست یابند. در این مطالعه، اثرات بهبود فضای کسب وکار و متغیرهای کنترل بر انبا...
In this paper, we empirically investigate the relationship between oil price changes and output in a group of oil exporting countries. The dynamics of business cycles in Libya, Saudi Arabia, Nigeria, Kuwait, Venezuela and Qatar are modeled by alternative regime switching models. We show that the extension of uni-variate Markov Switching model in order to include oil revenue improves dating busi...
Extramedullary plasmacytoma is rare in patients with diagnosed multiple myeloma. Soft tissue plasmacytoma of the gallbladder is particularly uncommon and has been described in only a handful of cases. Diagnosis of gallbladder plasmacytoma with fluorine 18-fluorodeoxyglucose (F18-FDG) positron emission tomography/computed tomography (PET/CT) has not previously been reported. We present a 65-year...
abstract the purpose of this paper is to test the hypothesis first proposed by romer (1993); suggesting that inflation is lower in more open economies. according to this hypothesis, central banks have a lower incentive to engineer surprise inflations in more-open economies because the phillips curve is steeper. furthermore, comparing with other empirical studies, this paper has used the new kof...
