Markups in a two‑country monopolistic competition model of trade with heterogeneous consumers
The paper develops a two-country monopolistic competition model of trade featuring country-specifc consumer tastes. The accounting for heterogeneity in tastes is achieved by assuming diferent elasticities of substitution in the CES utility function for diferent country consumers. The proposed framework extends the canonical Krugman’s approach by revealing new efects regarding markups response to consumer heterogeneity and trade liberalization. Specifcally, the model predicts that, depending on the preference structure, trade liberalization may lead either to decrease or increase in the level of markups, charged by monopolistically competitive frms across destination countries.
We present qqmbr, novel publishing system aimed at preparation of high-quality mathematical publications. One source can be converted to a single interactive webpage, multi-page website or PDF (via LaTeX). The markup language behind qqmbr entitled indentml is designed to be both human-readable and machine-readable (easily parsable). It is possible to extend basic qqmbr markup with custom tags that enrich its semantics and build plugins and applications that query qqmbr documents, extract information from them and process it in an arbitrary way without much effort.
The paper explores the evolution of trade and economic relations between Russia and Myanmar in 1948-2018. The author compares the quantitative and qualitative characteristics of Myanmar cooperation with China, India and Russia, highlighting their features and prospects. Summarizing the results, the author states that, despite the currently modest volumes of trade and investment, the potential for developing foreign economic relations between Russia and Myanmar is very high. However, Myanmar is an important link in the regional strategies of China and India, which also belong to the BRICS and the SCO. Therefore, it is impossible for Russia to build its political and economic ties with Myanmar without taking these aspects of regional relations into account.
The paper considers a model of monopolistic competition for the case of heterogeneous consumers, who differ from other with respect to product quality. To do this, a model of consumers, which in addition to the love of variety included a love of quality products. The industrial sector, in turn, consists of firms that produce a variety of differentiated products of different quality, focused on a certain type of buyer, i.e. the case of multi-product firms is considered. The function of supply and demand for the quality of goods is obtained, the equilibrium states in the long and short term are considered for two different situations when firms have market power in determining the quality of products and when they do not possess it.
The key issues of the theory and practice of modern trade policy and multilateral regulation of international trade in goods and services within the framework of the GATT/WTO system, including the use of trade regulation instruments, as well as the institutional framework of national and international trade regulation mechanisms are considered.
This collection includes scientific reports presented for participation in the International Conference: "The Evolution of the Global Trade System: problems and prospects" which took place on October 20-22, 2016 in St.Petersburg
Many industries are made of a few big firms, which are able to manipulate the market outcome, and of a host of small businesses, each of which has a negligible impact on the market. We provide a general equilibrium framework that encapsulates both market structures. Due to the higher toughness of competition, the entry of big firms leads them to sell more through a market expansion effect generated by the shrinking of the monopolistically competitive fringe. Furthermore, social welfare increases with the number of big firms because the pro-competitive effect associated with entry dominates the resulting decrease in product diversity.
This book contains a unique collection of studies on key economic and social policy challenges faced by countries of the Southern and Eastern Mediterranean region in a short- and long-term perspective. Prepared within the EU funded FP7 project on „Prospective Analysis for the Mediterranean Region (MEDPRO)” conducted in 2010-2013 it takes account on recent political developments in the region (Arab Spring) and their potential consequences. It covers a broad spectrum of topics such as factors of economic growth, macroeconomic and fiscal stability, trade and investment, Euro-Mediterranean and intra-regional economic integration, private sector development and privatizations, infrastructure, tourism, agriculture, financial sector development, poverty and inequality, education, labor market and gender issues.
The protracted nature of the current global financial crisis has led to reduced forecasts of economic and energy consumption growth accompanied by an obvious accelerated increase in the share taken by developing countries. • In the long term, fossil fuels will remain dominant, against the background of a slower growth in the share of non-hydrocarbon energy resources than was estimated in the previous Outlook. The ‘shale breakthrough’ has postponed for two or three decades the threat of running out of economically viable oil and gas reserves – which had seemed so close just five to seven years ago – and has secured the predominantly hydrocarbon character of the world’s energy sector. The share of oil and gas in world primary energy consumption will remain practically unchanged (53.6 per cent in 2010 and 51.4 per cent by 2040). • The study of oil and gas price dynamics in different scenarios did not show fundamental cause for alarmist forecasts predicting either too high, or extremely low, prices within the period under review. In all cases – ranging from future success to possible failure of shale technologies – oil prices in 2040 will not move out of the range $100–130/bbl. Gas prices will be closely correlated with oil prices, but also strongly differentiated by region (which does not exclude large short-term fluctuations in prices under the influence of political and speculative factors). • Despite the integration of oil and gas markets, as international trade in oil and liquefied natural gas (LNG) expands, the trend towards regionalization of prices, resulting in considerable differences in price levels, will gain momentum. • Natural gas will account for the most substantial increase in absolute volumes of consumption, and the share taken by gas in primary energy consumption will increase more than that of any other fuel. The next 30 years could, quite reasonably, be considered as ‘the era of gas’. But Russia runs the risk of missing the resulting opportunities. • The consequences of the expected transformation of world energy and, especially, hydrocarbon markets will not significantly change the fuel markets themselves, but the positions of the leading market participants will clearly be rebalanced, while some global players will be able to gain influence. The results of our research clearly show that Russia will be more susceptible to adverse changes in market conditions during the forecast period. In the Baseline Scenario, Russian oil and gas exports to foreign markets appear to be significantly lower than the official national projections. • High costs and the current taxation system both limit the competitiveness of Russian energy resources in global markets. The Russian fuel and energy complex could face severe restrictions on external demand for energy resources at prices acceptable to Russia, resulting in additional risks for Russia’s energy sector and economy. This research provides preliminary estimates of the consequences of this impact on the country’s economic growth (one percentage point slowdown per year) and possible measures to compensate for it.
We propose a model of monopolistic competition with additive preferences and variable marginal costs. Using the concept of "relative love for variety," we provide a full characterization of the free-entry equilibrium. When the relative love for variety increases with individual consumption, the market generates pro-competitive effects. When it decreases, the market mimics anti-competitive behavior. The constant elasticity of substitution is the only case in which all competitive effects are washed out. We also show that our results hold true when the economy involves several sectors, firms are heterogeneous, and preferences are given by the quadratic utility and the translog.
The paper examines the structure, governance, and balance sheets of state-controlled banks in Russia, which accounted for over 55 percent of the total assets in the country's banking system in early 2012. The author offers a credible estimate of the size of the country's state banking sector by including banks that are indirectly owned by public organizations. Contrary to some predictions based on the theoretical literature on economic transition, he explains the relatively high profitability and efficiency of Russian state-controlled banks by pointing to their competitive position in such functions as acquisition and disposal of assets on behalf of the government. Also suggested in the paper is a different way of looking at market concentration in Russia (by consolidating the market shares of core state-controlled banks), which produces a picture of a more concentrated market than officially reported. Lastly, one of the author's interesting conclusions is that China provides a better benchmark than the formerly centrally planned economies of Central and Eastern Europe by which to assess the viability of state ownership of banks in Russia and to evaluate the country's banking sector.
