Increasing returns, monopolistic competition, and international trade: Revisiting gains from trade
Journal of International Economics. 2022. Vol. 137. Article 103595.
We study the canonical Krugman (1979) trade model with non-CES preferences that yield autarky at finite trade costs. We prove a non-monotone impact of gradual trade liberalization. At first, near autarky, emerging trade reduces world welfare, while at free trade it becomes large enough to be beneficial (Krugman's result). This non-monotonicity persists under heterogenous firms. The harmful small-scale trade is explained by variable markups and underpriced
imports, which become socially excessive. Unlike protectionists, we argue that “liberalization should go far”. On the other hand, we show that anti-dumping measures can be viewed as a remedy for the aforementioned imports distortion. ©

Стремительно растущее население планеты и рост объемов индивидуального потребления при низкой включенности населения в экологические практики признается ключевым
препятствием на пути к экономике замкнутого цикла. В статье анализируется использование
огромного рекламно-коммуникационного потенциала крупных торговых сетей для вовлечения
населения в экономику замкнутого цикла через повышение экологической сознательности и популяризацию ответственного потребления. Эмпирической основой исследования стала база данных коммуникации шести ...

The study examined the properties of the normal distribution of the values of shipments of stocks of various categories from warehouses of large industrial companies. As a result, it was revealed that the use of the classical normal distribution, in some cases, may give incorrect results, since the values of stock shipments are positive values, ...

Innovative financing tools and models have proved their efficiency in supporting the adoption and scale-up of emerging technologies. They have been instrumental in different regions, including the Asia-Pacific region, which stands at the forefront of technological innovation. Studies point to several persistent emerging technological constraints that include high upfront capital costs, perceived risks, and limited ...

This paper studies a social-norm model in which agents choose effort in response to their own productivity and the efforts of their neighbours. We analyse how links between groups with different productivity levels affect equilibrium effort and derive the intergroup linking intensity that maximises aggregate effort. We work in a stylised two-group stochastic block setting ...

We revisit Krugman’s (J Int Econ 9(4):469–479, 1979.) classical trade model in its general form with several asymmetric countries and unspecified additive utility functions. We present the weakest known conditions on utilities sufficient for the existence of equilibrium. These conditions are also necessary under symmetric preferences. Using the same method for Bertoletti and Etro’s (Econ ...

This paper develops a modeling technique of “attainable profit” functions, applying it to two models of monopolistic competition. First, it revisits the Krugman's classical trade model in the most general form: several asymmetric countries and non-specified additive utility functions. We establish the weakest conditions on utilities, sufficient for the existence of equilibria. These conditions are ...

События последних лет указывают на развивающиеся в мире автаркические тенденции в научно-технологической сфере. В статье на основе нескольких кейсов рассматривается, как эти процессы протекают в российской науке. Изучаются параметры циркуляции исследователей, международное научное сотрудничество и его регулирование, инициированные государством изменения в грантовом финансировании исследований и подходы к строительству установок класса «мегасайенс». Циркуляция кадров в науке пока слабо выражена, причем приток происходит в основном из СНГ, а отток – в страны с развитой наукой. ...

Our novel approach enriches the general additive monopolistic competition model with a space of product characteristics: consumers’ “ideal varieties”. This paper bridges two traditions in modelling markets with horizontal product differentiation: the Hotelling’s (Econ J 39(153):41–57, 1929) “address economy” and Chamberlinian Dixit–Stiglitz monopolistic competition. Unlike Hotelling, our partially localised competition involves intersecting zones of service among producers. ...

We consider a general equilibrium model in a multisector economy with 𝑛 high-tech sectors where singleproduct firms compete monopolistically producing a differentiated good. Homogeneous sector is characterized by perfect competition. Workers attempt to find a job in high-tech sectors because of higher wages. However, it is possible for them to remain unemployed. Wages of employees ...
