English Abstract: The Brexit referendum, which took place on 23 June, 2016, revealed the British people's willingness for their country to leave the EU. The year 2017 will witness the beginning of Brexit negotiations between the UK and the EU taking place in a time full of uncertainties arising from the possibility of the negotiations extending beyond the originally planned duration of two years, ambiguity in EU’s competency areas leading to a complicated decision-making process in the Council, whether or not British MEPs should be given voting rights in the European Parliament, and so forth. One of the key issues in the relation between the UK and the EU in the post-Brexit era is whether or not the UK maintains full access to the Single Market, which is directly related to the issue of if the principle of free movement of the four factors of people, capital, goods and services still holds after Brexit. It will be a key factor to evaluate accessibility to the Single Market if British sovereignty on commercial policy and immigration is restored, and the principle of homogeneity does hold. Thinking carefully over several cases of the models of Single Market, half Single Market, or non-Single Market would lead to a pessimistic reasoning that the UK would hardly be able to maintain Single Market accessibility, and be inclined to take the non-Single Market model.","PeriodicalId":341166,"journal":{"name":"PSN: Trade Relationships (Topic)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126528757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If large differences in economic and living standards continue to exist between the two countries after unification it will be difficult to restrict migration from North to South. In that case, South Korea will have to bear an enormous social cost for accepting and assimilating those immigrants from North. Such social costs include the cost for job training, unemployment insurance, and to deal with social conflicts. To control the cost of migration from North to South Korea it will be necessary to vitalize the North Korean economy by reforming the very inefficient economic system that exists in the country. \u0000Trade liberalization is a very powerful driver when it comes to improving economic efficiency. The knowledge spillover effect realized through procurement of intermediate products from advanced countries is expected to contribute to upgrading North Korea’s production technology. Furthermore, the increased competition from imported goods should lead to the improvement of misallocation of production resources in the economy. \u0000When we analyze the effects of trade liberalization on economic development in the current economy, we should take into account not only the effects of the international trade of final goods but also those from the trade of parts and components. Multinational firms in advanced economies relocate their labor-intensive work to developing countries and have established global value chains (GVC). Hence, the trade relationship between countries has become more complicated and sophisticated in the current global economy. In addition, the establishment of GVCs has changed the nature of international trade and foreign direct investment. For example, an increase or decrease in automobile exports from China to the USA does not influence only the two countries' economies but also influences the Japanese economy, as Japanese manufacturers export intermediate products to Chinese automobile manufacturers.","PeriodicalId":341166,"journal":{"name":"PSN: Trade Relationships (Topic)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124089002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But that is far from the whole story because trade multilateralism today is about third-generation big tent trade agreements embodying the invasive presence of global neoliberalism to reach behind borders of states and challenge the sovereignty of governments. For European and Canadian citizens these megadeals are in the crosshairs of threatened citizens worried about their employment prospects, food security, the environment, intellectual property rights, the costs of generic drugs and most importantly the growing specter of investment protectionism. Investor protectionism has been around for a long time but the state investor dispute mechanism in both these trade agreements – to a degree that did not exist previously under the GATT System – now gives global corporations the legal right to sue governments on narrow commercial grounds. Governments increasingly are unable to control the trade governance agenda and the election of Trump has created new instability and uncertainty about the future of trade multilateralism, particularly with regards to NAFTA and other agreements.","PeriodicalId":341166,"journal":{"name":"PSN: Trade Relationships (Topic)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116421731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need to secure resources to meet the development aspiration of her country made China to increasingly forged formidable trade ties with almost all African countries, especially Nigeria, in the area of manufacturing products. While these realities have proved to be beneficial to the trading partners, there is still skepticism about the benefits of such trade relations to Nigeria. There is a perceived dis-proportionality in the quantum of bilateral inflow of manufacturing products between Nigeria and China. This study therefore addressed these concerns by applying gravity model to analyze the determinants of bilateral trade relation in manufacturing products between Nigeria and China for the period of 1995 to 2012. Thus, from the stylized facts, we find evidence of increasing influx of China manufactured products into Nigeria while that of Nigeria outflow to them is of low magnitude. This paper therefore recommended the diversification of economic base of Nigeria crucial for a more beneficial China-Nigeria bilateral trade in manufactures.","PeriodicalId":341166,"journal":{"name":"PSN: Trade Relationships (Topic)","volume":"456 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128444056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to achieve such a goal, problems of official and unofficial reports related to the subject are presented first. Then, original estimates are drawn by utilizing firm-level overseas direct investment data and proxy variables. The estimation process starts from aggregation of data appeared in all press releases and earlier studies. A basic analysis on collected items suggests that China's ODI on North Korea has continuously increased from 2004 to 2012, except for a brief period around Pyongyang's second nuclear test in 2009. Investments seem to enter a downturn after the third test in 2013. Such a trend matches the one suggested by China's Ministry of Commerce(MOFCOM) by and large; however, there was a big difference between the two in volume and trend of ODI from 2004 to 2005. Therefore, some revisions are needed to obtain reasonable time-series data. This paper suggested the first stage estimates by matching former data of Chinese firms to newly obtained lists. The number of samples is almost doubled even after filtering out flawed ones. Based on a more reliable set of data, estimated amount of China's investment on North Korea after 2000 is 759.98 million dollars total. This estimate is 1.74 times larger than figures reported in MOFCOM, implying that a significant portion of ODI turns out to be unrecorded especially during 2005-2007.

We argue that the usual specification leads to invalid out-of-sample predictions, biased coefficients and moreover it ignores heterogeneity. The proposed model is estimated for a sample of 188 countries over the period 1988-2013 using panel fixed effects and PPML techniques and the resulting trade elasticities with respect to aid are compared with those obtained from the traditional specification. The main results show that average effect of one additional US $ of aid is around 0.56$ of total imports according to our model, whereas with the alternative model an average effect of an implausible amount of 11$ of imports is obtained. In addition, a decomposed version of the model provides a new framework to disentangle the political effects of aid from the budget effects. While we consider the case of foreign aid, the modeling framework also applies to the study of other transfer, as for example remittances.","PeriodicalId":341166,"journal":{"name":"PSN: Trade Relationships (Topic)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121789187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This risks raising the overall level of regulation higher than is necessary and embedding systemic risks. If the UK votes to remain in the EU, Britain should focus on changing the overall institutional structure in a more free-market direction. This agenda should focus on institutional change, rather than the repeal or refinement of particular directives. Alternatively, it will probably take a long time for Britain to disentangle itself from the EU policy. Moving towards a more classical liberal Britain is therefore a long-term endeavour. It seems likely in the event of a Brexit that the government and civil service will push for the UK to join the European Economic Area. This brings with a repatriation of some powers, but does not fully restore control across a range of economic areas. To realise the true gains from Brexit, the EEA must, in these circumstances, be very much a transitional arrangement.","PeriodicalId":341166,"journal":{"name":"PSN: Trade Relationships (Topic)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129892824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These have been analyzed through use of Shift-Share and Constant Market Share analysis. The analysis of bilateral trade between the two countries indicates that the commodity mix changes from time to time. The constant market share (CMS) analysis shows that the world trade has little effect on India while the reverse is true for Canada. Thus the shift in trade between the countries can be attributed to world trade effect, competitiveness and market distribution effect. It further elaborates and reviews the research done in the field of trade and identifies the dimensions that govern the trade dynamics. It proposes a causal model that substantiates and explains the cause and effect of various dimensions ultimately impacting the trade between the two countries. The System Dynamics model takes into account the different perspectives of international trade namely, free trade, fair trade, conflict, national and global economy, endowments, trade-balance and externalities. The various policies that undergo change as a result of interplay of these dimensions include monetary and fiscal and trade policies (tariff and non-tariff barriers). The model reveals five loops. The properties of these loops have been explained identifying them as positive and negative loops. The paper concludes by proposing a framework that would enable the planners to frame, execute and review bilateral trade agreements such as the Comprehensive Economic Partnership (CEPA) under formulation between India and Canada, keeping in view the outcome of proposal to allow FDI in retail sector in India and failure of different trade treaties such as US-Korea trade treaty initiated in 2007.","PeriodicalId":341166,"journal":{"name":"PSN: Trade Relationships (Topic)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132111228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
