In this collection of essays, I explore three topics where space and distance plays a fundamental role in international economics. Not only do spatial considerations affect the pattern of trade, the frictions that arise from distance also determine where and how goods are produced and where people live. In Chapter 1, I show that human made locational characteristics can determine the spatial allocation of economic activity. I take the standard core-periphery model and add endogenous housing to its forward-looking dynamic adjustment process. By introducing a model of adjustment with an extra state variable, which I interpret as housing, I show that the distribution of housing allows the model to converge to a unique spatial equilibrium. This explains the observed persistence and robustness of economic agglomerations in the data. Chapter 2 is a theory of task assignment in the production of final goods and across countries. By allowing for tasks to differ in their suitability of being used in the production of multiple goods, my model endogenizes the allocation of tasks in the production of goods that use them. The resulting equilibrium task allocation defines the pattern of off-shoring. Tasks that are used in only one good concentrate in the country with a specialization in production of that good. Tasks used in many goods are allocated across countries, with the more substitutable tasks located in the country with the larger overall output. Gains from off-shoring are derived from a better mix of allocation of tasks into goods as well as larger scale of production. Finally in Chapter 3, I study how real exchange rate fluctuations determine the size and composition of the export sector. Using the methodology set out in Dixit and Pindyck (1994) in a heterogeneous firms model, I determine the set of trigger real exchange rates for entry and exit into exporting. My primary result of this chapter is that exchange rate uncertainty coupled with sunk cost of entry causes hysteresis in the number and productivity of exporting firms. I then extend the model to allow free entry of firms. This explains the stylized fact of the existence of non-exporting firms with higher productivity than some exporting firms.

The European Union-South Africa Trade, Development and Co-operation Agreement (EU/SA TDCA), signed in October 1999, is viewed by some in South Africa as not only one of the most important trade and development agreements entered into by the 'new' South African goverrunent, but also a significant agreement for setting precedents for other bi-lateral trade and development pacts between the EU and African, Caribbean and Pacific group of states. This thesis considers two major issues related to the EU/SA TDCA. First, it describes and evaluates the structures that supported the South African side of the TDCA decision-making process. Second, it discusses the potential economic impact of the agreement on South Africa and part of southern African. Prior to the election of the 'new' South African government in 1994, the majority of South Africa's population was excluded - both in terms of access to decision-making structures and from economic prosperity. By exploring the TDCA, the thesis provides a window through wl-dch to examine contemporary access to decision-making processes in South Africa and the likelihood of the TDCA promoting economic prosperity for sections of southern African society, particularly the 'traditionally excluded'. Interviews with key actors who helped formulate the TDCA provide information that enabled the evaluation of the TDCA decision-making process and highlighted potential economic 'winners' and 'losers'. Interviewing representatives of the South African wine and textile sectors provided an opportunity to examine in more detail the likely impact of the agreement and decision-making processes, associated to the TDCA, within South Africa. The results indicate that an overriding message of this thesis is one of complexity. The description of the structures that underpinned the EU/SA TDCA portrayed complex relationships between decision-making 'actors'. In evaluating the inclusivity of the policy formulation process, there was a lack of consensus over who had been included or excluded. Likewise, the identification of potential economic 'winners' and 'losers' proved to be somewhat problematic.

The objective of this thesis is to highlight the Egyptian experiment concerning its economic reform programme, and to determine whether this programme has affected Egypt's stock market performance. Using 18 years of data, which covered the period 1980/8 1 to 1997/98 and incorporates time periods prior to and after adopting the economic reform programme, the thesis empirically investigates three main issues. Firstly, there is an examination of whether the Egyptian government succeeded in implementing its economic reform programme by looking to the main economic indicators: nominal interest rates, real interest rates, the inflation rate, exchange rate stability, the real GDP growth rate, per capita income and the budget deficit in Egypt after 1991, and comparing them with the same indicators prior to this period. Secondly, the thesis considers the changes in Egypt's stock market after the introduction of the economic reform programme by measuring the changes in four main dimensions: market activity, market size, market liquidity and market concentration. Thirdly, and this is the main part of the thesis, the research concentrates on examining the impact of Egypt's economic reform programme on its stock market performance. For the first two issues, several logistic regressions are performed to determine whether the data prior to 1991 can be separated from the data relating to the period after 1991. The results from this analysis indicate clearly that both type of data series witnessed dramatic changes after 1991. As to the third issue, cointegration analysis is used to model the relationship between economic reform programme variables and the stock market performance variables within an error correction model form. Generally speaking, the results from this analysis demonstrate that economic variables have an impact upon various features of market activity, market size, market liquidity and market concentration. An important observation in this thesis is that Egypt still needs to accelerate its rate of growth, as it was the only independent variable, which did not show any significant change or significant impact upon the stock market performance variables.

This dissertation consists of four related, sole-authored chapters. It considers the microeconomic mechanisms for gains from trade in the presence of quality investments by firms. It shows within the framework of a quality-augmented heterogeneous firms model that the quality dimension matters for welfare gains from trade. It also provides novel empirical evidence on adjustment mechanisms of aggregate quality as a consequence of globalization. To the best of my knowledge, this is the first contribution to provide a comprehensive analysis of the role of endogenous product quality in the determination of gains from trade. I first offer an explanation for observed industry heterogeneity in trade-induced productivity gains and show that results depend on whether or not firms have the option to invest in quality. I then take a broader view of welfare gains from trade, looking beyond productivity improvements. I find that globalization can imply a quality-variety trade-off when consumer quality preference is strong - a finding which holds under firm heterogeneity and symmetry. Nevertheless, overall gains from trade are positive. With quality being itself an important channel for gains from trade, I also investigate the detailed mechanisms by which aggregate quality changes as a consequence of globalization. This is done within the same theoretical heterogeneous firms framework as well as empirically using firm-level export data matched with firm-level quality ratings. I argue that firm heterogeneity matters for gains from trade by giving rise to an additional welfare channel in the presence of variable elasticity of demand preferences: high quality firms expand sales disproportionately in a larger market, thereby raising aggregate quality. This theoretical prediction is confirmed by the data. Furthermore, I study the mechanisms for gains from trade in a symmetric firms version of the baseline model. This allows me to isolate the role of firm heterogeneity in driving earlier results. In addition, I analyse the efficiency properties of the market equilibrium for the symmetric firms case.

This thesis is focused on forestry economics and timber industry and present state of the Czech foreign commerce with raw food. Finally, there are determined critical factors, proposals and recommendations.
