Structural change, convergence and networks: theoretical and empirical analysesDutta, Aparna 08 April 2016 (has links)
The dissertation consists of three chapters that study topics related to structural change, spatial and network data.
The first chapter considers the problem of testing for a structural change in the spatial lag parameter in a panel model. We propose a likelihood ratio test of the null hypothesis of no change against the alternative hypothesis of a single change. The limiting distribution of the test is derived under the null hypothesis when the number of time periods is large. We also propose a break-date estimator to determine the location of the change point following evidence against the null hypothesis. We present Monte Carlo evidence to show that the proposed procedure performs well in finite samples. We use US state budget data to investigate changes in budget spillovers and the interdependence of fiscal policy within US states.
The second chapter proposes a theory of cross-country migration in the form of labor mobility based on regional and sectoral productivity shocks in a multi-country, multi-sector setting. The productivity model when applied to US state data explains both the nominal and relative flow of workers across the U.S. well, which is taken as the frictionless benchmark. On the other hand, when applied to Europe the model explains the relative flow network well, but predicts a higher nominal flow. This missing mass of migrants is explained by socio-cultural-political barriers. We use dyadic regressions to assess the effects of institutional and cultural "distance" between countries in explaining the "European immobility puzzle".
The third chapter shows that the "iron-law" of convergence (2\%) still holds for the world. We document a structural break in Africa's convergence rate and argue that Africa was not converging before 2000. The world convergence rate before 2000 was driven by Asian and Latin American countries. We show that recent institutional and infrastructural developments have led the African countries on the path of "catching up". We use Least-Absolute-Shrinkage-and-Selection-Operator (LASSO) to select the variables and a double selection method to estimate the treatment effect in a partially linear model. We compare LASSO variable selections with those obtained using Gradient-Boosting-Method (GBM) and Random Forest.

Public procurements in Africa : - the way to Swedish successRamebäck, Anna January 2007 (has links)
<p>Africa is a poor continent with many of the worlds least developed countries. The latest years the Swedish export to Africa has diminished, at the same time Sweden continues to be a big contributor of aid funds to the continent. However, trade in all its form contribute to prosperity in the trading countries which indicates that the trade with Sweden could help Africa to develop into a bigger and more important economy. Also, since trade increases a country’s welfare, both the Swedish and African societies could benefit from an increased trade between the countries.</p><p>By getting involved in public procurements in Africa the Swedish companies would get an economic security in the otherwise quite risky market. The public procurements could also mean a way to enter the market or to increase the market shares in Africa. This Thesis is focused on public procurements from the African Development Bank, mostly since Sweden is a big contributor in the bank but only a few Swedish companies has won contracts from the bank and also because many studies has not been made regarding their procurement process.</p><p>By using theories mainly from project marketing and networking, the market of public procurements in the African Development Bank, the process and the ways to succeed on this market has been studied.</p><p>It has been showed that the competition for the procurements from the bank is hard, and that the Swedish companies have not been successful. There are many underlying reasons for this, one of the most important being the fact that the Swedish companies have not even been interested in participating in the procurements since they find the market, the process and the bank to complicated. New possibilities are emerging on the market with the African Development Bank improving the efficiency of the procurement process, more lobbying being performed from the Swedish Foreign Ministry and also the growing African market, which makes this market more interesting and could mean new opportunities for the Swedish companies.</p><p>To improve the Swedish statistics in winning contracts from the bank the Swedish companies need to improve their networking to a great extent. Personal contacts and relationships are extremely important in making business in Africa and also when making bids on procurements from the bank. From the relationships in Africa, the Swedish companies can receive early information about upcoming projects in order to prepare the bid and market the company early. The Swedish companies must be more proactive in their marketing and visit Africa more often, as well as matching the needs with their offer to a better extent than today. It is important for the companies to have a long-term strategy when entering the African procurement market and not to resist too easily. Hard work and many resources will be spent before being awarded with the first contract and thereafter one success will lead to others.</p>

The Southern African Development Community : - A successful regional organisation?Sundkvist, Daniel January 2009 (has links)
<p>This essay deals with the topic of regional integration in Africa. Using the Southern African Development Community (SADC) as an example, it seeks to answer the question what constitutes a successful region organisation. To do this a number of criteria defining success were developed and subsequently applied to the SADC, the main one beeing the organisations ability to adapt to change. In order to be able to show whether and how the SADC has reacted to and accommodated changes, the analysis was built around a description of the historical evolution of the SADC(C). The changes made by the SADC (political structure, membership, goals) have been summarised and assessed. Special attention was paid to the (potential) problems identified by Winfried Lang (1982).</p><p>Guided by the thoughts of Winfried Lang and the criteria used in this essay defining what constitutes a successful regional organisation, we find that the Southern African Development Community is rather successful. The SADCC seems to have created a good basis for integration, and the organisation has proven ist ability to adapt to changes, even if they are as all-embracing as the end of the apartheid regime in the RSA and the subsequent membership of the former opponent. One can thus suppose that the SADC could, if necessary, accomodate changed circumstances again, and is thus unlikely to become one of the many failed regional organisations in Africa.</p><p> </p>

Considerations for the creation of a SADC Reserve Bank : a Namibian perspective.Krohne, Maryke Veretta Caroline. January 2006 (has links)
This study is concerned with the feasibility and problems associated with the timely establishment of the SADC monetary union and central bank. During this study an indepth literature review was done to analyse / establish the historical background for the establishment of the monetary union for SADC, to look at the reason for a central bank's existence and the functions performed by the central banks in the region. The study looks at the benchmark used for the establishment of this monetary union, this being the European Union. It looks at the establishment of the monetary union from a political, central banking, commercial banking and business perspective and also how these entities will be affected by the establishment. The study aims at looking at the problems that might prevent the SADC region from reaching the expected implementation date of 2016 and to make some recommendations to assist the different parties to best prepare for the successful implementation of this monetary union for SADC. / Thesis (MBA)-University of KwaZulu-Natal, Westville, 2006.

Trade patterns and foreign direct investment in the Southern African development community / Henri BezuidenhoutBezuidenhout, Henri January 2007 (has links)
This thesis focuses on the relationship between trade and FDI in the SADC. While FDI is
seen as a stimulus for growth and development, Africa is lagging behind other regions
in attracting FDI. Whilst a number of reasons have been explored in the literature, the
potential link between trade and FDI has not been explored in the African context. This
may be potentially important, since African governments have been engaging in trade
liberalisation and trade promotion over the past two decades. In this thesis, gravity
modelling is used to investigate the trade-FDI relationship. Two single equation
regression models are used in a preliminary investigation to evaluate aggregate trade
and FDI. The third model consists of six panel regressions that evaluate the different
relationships between the individual SADC countries and their individual major trading
partners. A causality test is also carried out to confirm the relevance of trade as a
determinant of FDI in the SADC. Overall results indicate that, in the specific case of the
SADC, SADC exports significantly cause FDI. Distance from home countries and
political instability are the most significant negative forces that affect FDI inflows. Home
country exports deliver mixed results and these results suggest that the United States
and the United Kingdom have a different FDI-trade relationship with the SADC than
continental Europe, whereas Japan's exports prove insignificant. The policy implications
are that the SADC will need to focus on attracting investment from countries that
provide for complementary FDI and trade as this is optimal for poverty alleviation and
job creation. Further research should focus on these policy areas and take into account
the relevance of trade as a determinant of FDI. / Thesis (Ph.D. (Economics))--North-West University, Potchefstroom Campus, 2007.
