Economic analysis of intra-industry trade : the case of South Africa’s automotive industryDamoense-Azevedo, Maylene Yvette 13 October 2011 (has links)
Over recent years, international trade flows of automotive products have experienced rising trends. Thus, the need to gain a better understanding of trade theories that could explain such trade flows. Until recently, the theoretical and empirical distinction of intra-industry trade (IIT) into patterns of horizontally differentiated (by variety) intra-industry trade (HIIT) and vertically differentiated (by quality) intra-industry trade (VIIT) has become crucial because each IIT pattern may potentially be influenced in different manners by country and industry factors (Greenaway, Hine&Milner, 1995). The objective of this thesis is twofold. Firstly, to measure the empirical significance of IIT in the automobile industry between South Africa and its bilateral trading partners and to decompose total IIT (TIIT) into VIIT and HIIT patterns. Secondly, to develop empirical models to investigate potential country- and industry-specific determinants of IIT patterns in the South African automobile industry. The empirical strategy adopted in this thesis is a gravity model spanning the period 2000 to 2007. The automobile industry is a principal industrial sector in the South African economy contributing notably to trade, investment, employment and national output. The structure and conduct of the industry is aligned with several elements of IIT theories and thus represents an important and fascinating case of IIT patterns to investigate. Therefore, the findings of this thesis will be valuable to trade policy analysts and manufacturers in the local and global automotive industries. According to the objectives, the significance of IIT is estimated using the trade overlap index and the empirical separation of total intra-industry trade (TIIT) into VIIT and HIIT is conducted using the threshold method. The empirical results reveal the presence of significant levels of IIT in automotive trade flows between South Africa and its bilateral trading partners. In accordance with theoretical expectations, the empirical investigation signifies the existence of high shares of VIIT dominating TIIT in the South African automobile industry. Moreover, the empirical analysis postulates that, within VIIT, the domestic automobile industry potentially produces and exports high quality automotive products proposing that such VIIT can be partly explained by fragmentation and international production processes. Next, gravity models are estimated to investigate the determinants of IIT patterns in the automobile industry. The econometric results of the gravity models of VIIT, HIIT and TIIT are statistically and economically significant in the context of the fixed effects method of estimation and in accordance with new trade theories. The empirical results reveal that relative difference in economic size, trade openness, foreign direct investment (FDI) and tariffs stimulates VIIT, whilst distance, economies of scale and automotive assistance negatively affect it. Conversely, relative difference in economic size, FDI and automotive assistance negatively affects HIIT, whereas trade openness and depreciation of the exchange rate positively influences it. Thus, the findings of the thesis assert that IIT patterns of VIIT and HIIT in the automobile industry are influenced differently by country and industry determinants, revealing that the theoretical and empirical distinction of TIIT is important. The thesis proposes advancing trade liberalisation and deregulation of the South African automobile industry that could attract greater efficiency-seeking FDI complementary to trade and as a consequence enhance IIT levels. / Thesis (PhD)--University of Pretoria, 2011. / Economics / unrestricted

Bilateral shipping and trade : Swedish-Finnish experiences in the post-war period / Bilateral handel och sjöfart : Svensk-finska erfarenheter under efterkrigstidenAndersson, Lars Fredrik January 2005 (has links)
This thesis explores the bilateral shipping and trade between Finland and Sweden during the post-war period. It comprises five articles and one introductory chapter for which the common point of departure is the growth and transformation of bilateral trade and shipping. The first two articles analyse the structural change of bilateral trade from a national and regional perspective. The three following articles provide an overview and analysis of the ferry shipping. By integrating the perspective in these articles in the introductory chapter and by providing a long historical record, the change of economic relations between Finland and Sweden in the post-war period is discerned. This thesis applies an economic historical approach and is founded on various fields of social science. The issue of trade is analysed within the framework of conventional and new trade theory, and the analysis of ferry shipping is governed by economic and geographic theories. The studies on trade shows that the transformation of production seen in Finland and Sweden meant that the trade increasingly became dependent on an exchange of products arising from matching industries. In turn the foreign trade arising from the Northern part of Finland and Sweden was still dominated by so called inter-industry trade. In addition to these results, the studies of ferry services shows that the growth of vehicles and passengers conveyance, together with the expanded onboard services, also intensified the commercial exchange. Due of the multi-output structure, the ferry service efficiently met the growing demand of travel and trade. The main conclusion of this thesis is that the convergence of incomes and economic structure had a significant impact on bilateral trade and ferry shipping. In addition the process of economic integration, technological advances together with specific policies issued on shipping also contributed to strengthen the economic ties between Finland and Sweden.
