The research problem undertaken by the authors of this article concerns the optimization of the size of the distribution network (the number of warehouses). The authors developed regression models, which are an alternative to the classical “Square Root law” optimization formula. The models were built for the two distributions of demand most commonly used in the literature: Gaussian and Gamma distribution. They allow the calculation of the level of inventory with a given number of warehouses and the level of stock availability as a measure of logistic customer service. The aim was to create a useful tool for decision-makers in companies. The models were elaborated on the base of the simulations carried out for various products (loading parameters, value), sales volumes, number of warehouses, and different standard deviations. Both regression models were statistically significant; the coefficients of determination are relevant. A slightly better value was obtained in the case of Gaussian distribution. The results obtained with the use of the classic “Square Root law” were in some cases quite similar. However, the type of distribution and the variability of demand, measured by standard deviation, have a significant influence here. Thus, the authors believe that the models developed may give more accurate results and that the “Square Root law” formula should be modified taking into account the characteristics of the demand. After completing the regression models with cost components, the total costs were calculated for selected cases of product groups (food, electronics, garments), different levels of the availability of stocks, and different number of warehouses. As it turned out, centralization may not necessarily be the optimal strategy for the most expensive goods. Loading parameters are also important, as they have a significant impact on the costs of storage and, above all, transport.

The passage through the Panama Canal has become the usual waterway for all the ships that can navigate through the Canal. The traffic through the canal is limited by the size of a ship. The need for the expansion of the Canal has emerged due to the development of the global trade and the shipping industry. The new dimensions of the lock‐chambers determine the size of the ships as well. The new generation of ships built to the largest specifications possible to transit the current locks of the canal are called the Post‐Panamax vessels. The maximum dimensions of these ships are 366 meters in length, 49 meters in beam and 15.2 metres in draught. The paper analyses savings in the operational costs on three types of the Post‐Panamax vessels after the Canal expansion.

This survey reviews the current state of the economic literature, assessing the impact of transport policies on growth, inclusion, and sustainability in a developing country context. The findings are summarized and methodologies are critically assessed, especially those dealing with endogeneity issues in empirical studies. The specific implementation challenges of transport policies in developing countries are discussed.

The authors use different data sets to investigate the dependence of transport costs on geography and infrastructure. Infrastructure is an important determinant of transport costs, especially for landlocked countries. Analysis of bilateral trade data confirms the importance of infrastructure and gives an estimate of the elasticity of trade flows with respect to the trade cost factor of around-3. A deterioration of infrastructure from the median to the 75th percentile raises transport costs by 12 percentage points and reduces trade volumes by 28 percent. Analysis of African trade flows indicates that their relatively low level is largely due to poor infrastructure.

In considering the prospects for expanding non-commodities exports, the SACU region faces a global environment that has changed markedly over the past two decades. First, trade is increasingly shifting away from high income countries and toward developing countries. Second and perhaps most importantly, is the increasing importance of or ‘global production networks’ or ‘global value chains’ (GVCs). With wages rising rapidly in China and other places where GVC-oriented trade is concentrated, parts of these value chains are migrating to new global locations. Some estimates indicate that over the next generation 85 million manufacturing jobs will migrate from coastal China, and Sub-Saharan Africa is expected to be a major beneficiary. The SACU region, with its abundance of natural capital and surplus labor, along with a relatively high quality infrastructure and institutional environment, should be in a good position to attract investment and create a ‘factory Southern Africa’. Beyond assembly manufacturing that is typical of GVCs (e.g. apparel, electronics, automotive), the region should also be well-placed to compete as a location for value-addition to agricultural and mineral commodities (‘beneficiation’). Both types of investment would not only drive exports and have the potential to create significant employment, but also support upgrading by accessing global technologies and knowledge. And with growing markets across Africa, a ‘factory Southern Africa’ might increasingly be sustainable in the regional context.

The trade facilitation facility (TFF) was launched to help low-income countries improve their competitiveness by reducing the costs of engaging in international trade, thus supporting their efforts to reduce poverty and achieve the millennium development goals. This report summarizes the outcomes of the TFF between its establishment in 2009 and its end in 2015. The report highlights and reviews the accomplishments and lessons learned of TFF; it also discusses and reflects the perspective of task team leaders and relevant World Bank Group officials on the Bank Group’s continuing work in the trade facilitation sphere. The report presents results of TFF-funded activities and programs managed by staff from a large cross section of Bank Group sectors, including transport, agriculture, governance (customs), international trade, and private sector development. The report is organized as follows: chapter one give introduction. Chapter two provides an overview of the TFF portfolio. Chapter three looks at TFF as enabler of deepening regional integration, highlighting some of the facility’s accomplishments from a geographic and thematic perspective, particularly the extent to which TFF complemented Bank infrastructure operations and nurtured progress on trade facilitation instruments that countries and regional economic communities (RECs) have adopted but failed to implement. Chapter four, expanding thematic insights, addresses conceptual themes in trade facilitation. Chapter five, conclusions and contributions, sums up the areas in which TFF has contributed to moving the regional and multilateral trade facilitation agenda.

The petroleum sector contributes substantially to the Nigerian economy; however, the potential benefits are diminished because of the existence of significant subsidies on imports of petroleum products. Subsidies on imported petroleum products are considered to be an important instrument for keeping fuel prices, and hence the cost of living, low. The costs of these subsidies, however, have risen dramatically in recent years along with increased volatility in world petroleum and petroleum product prices and increased illegal exportation of subsidized petroleum products into neighboring countries. Removing the subsidy on fuel is one of the most contentious socioeconomic policy issues in Nigeria today. In this paper, an economy-wide framework is used to identify the impact of removing the fuel subsidy on the Nigerian economy and investigate how alternative policies might be used to meet socioeconomic objectives related to fuel subsidies. The results show that although a reduction in the subsidy generally results in an increase in Nigeria’s gross domestic product, it can have a detrimental impact on household income, and in particular on poor households. Accompanying the subsidy reduction with income transfers aimed at poor households or domestic production of petroleum products can alleviate the negative impacts on household income.

In Zimbabwe trade has been a driver of economic growth, rising incomes, and progressive empowerment of Zimbabweans through rising standards of living and the promise of better jobs. Since 1980, through good years and bad years, increases in exports have been positively associated with increases in national income. Zimbabwe's location and resource base, together with a low-cost but relatively well educated labor force, have endowed it with a naturally high trade ratio built on a diversified base that facilitates using trade as an engine of growth. While trade volumes have rebounded smartly from the deep recession of 2007-2008, these do not offset other worrisome longer-term trends: 1) export growth during the last decade has been lackluster and failed to drive high growth; 2) agricultural exports, other than tobacco, have lost their once dominant role in the region, and are no longer a source of diversification; 3) manufacturing has withered in a continuing secular decline; and 4) Zimbabwe's export basket has become less diversified and more dependent on a narrow range of mineral and, to a lesser extent, agricultural products. In short, exports have become less diversified, less-technologically sophisticated, and less labor-intensive, and ever more dependent on a few large mining activities to provide foreign exchange and employment. This report traces the roots of this poor performance to several policy issues: poor predictability of macroeconomic policy and economic governance has created an unfavorable climate for private investment and trade; a tariff structure that dampens export profitability; industrial policies (indigenization policy in particular) that undermine investor confidence and inhibits private investment; and finally, competition-limiting policies toward services that limit connectivity of Zimbabweans and raise trade costs. The good news arising from the study is that the remedies for these policy shortcomings lie in Zimbabwean hands. If the government were to adopt reforms that reconfigure economy-wide incentives and trade and industrial policies, it could promote sustained growth, economic diversification and empowerment of poor people.

The Government of Benin has requested an update of the 2005 Diagnostic Trade Integration Study and has asked the World Bank to take the leading role in this exercise. The update’s objectives are to (a) take stock of progress in the mainstreaming of trade in the government’s national development strategy and of implementation of the Action Matrix recommendations; (b) complement and deepen the analysis in selected areas; and (c) revise and update the Action Matrix to take account of the evolving context since 2006. The aim of the analysis is to assist the Government of Benin in defining an overall competitiveness strategy for inclusive, job-creating export-led growth in accordance with the key priorities identified in the 2013 Plan Stratégique de Développement du Commerce (PSDC), and to further mainstream trade into the general policy orientation defined by Benin’s key policy documents, including the Growth and Poverty Reduction Strategy Paper (GPRSP) update. The DTIS Update (DTISU) offers a diagnosis, analytical framework and action plan, giving trade expansion a key role in the reduction of poverty and vulnerability. As mandated by the Paris Principles, the DTISU’s approach is strongly aligned with the MICPME’s PSDC (Trade Development Strategy Plan, henceforth TDSP) and draws also from the diagnosis in the Government of Benin’s recent poverty assessment (INSAE 2014) as well as the 2011 update of the GPRSP. It emphasizes the linkages between poverty, jobs, and trade with two key objectives: (i) reducing poverty through trade-led growth, and (ii) reducing vulnerability.

It is widely accepted that the costs of underpricing energy are large, whether in advanced or developing countries. This paper explores how large these costs can be by focussing on the size of the external effects that energy subsidies in particular generate in two important sectors—transport and agriculture—in two countries in the Middle East and North Africa, the Arab Republic of Egypt (transport) and the Republic of Yemen (agriculture). The focus is mainly on the costs associated with congestion and pollution, as well as the impact of underpriced energy for depletion of scarce water resources, including through crop selection. Quantifying the size of external effects in developing countries has received relatively little analytical attention, although there is a significant body of literature for developed countries. By building on earlier research, as well as employing the United Nations ForFITS model, the paper provides indicative estimates of the external costs of energy subsidies, as manifested in congestion and pollution. The estimates using simulations indicate that these costs could be materially reduced by elimination or reduction of energy subsidies. The paper also describes the impact of energy subsidies on water consumption in a region where water resources are particularly limited. The findings provide further evidence of the adverse and significant consequences of subsidizing energy.

This report focuses on areas with highest potential efficiency gains to increase the value for money from investments in core public goods and services such as extension, irrigation and rural roads. This is a first attempt to carry out such an analysis in Cambodia, and even in the Greater Mekong sub-region. Based on extensive data gathering and surveys, this chapter analyzes the efficiency and effectiveness of agricultural sector expenditures in Cambodia and assesses various options for increasing the impact of government expenditures on agricultural growth. Other challenges include an excessive focus on rehabilitating primary irrigation infrastructure and a neglect of secondary and tertiary systems, a lack of maintenance of irrigation and rural roads, and the slow pace of developing or adopting new technologies to reduce future maintenance costs. There is also a need to better prioritize agricultural and related infrastructure expenditures, both by type and by geographic location, to maximize their impact on growth. The rest of the report is organized as follows. Chapter two presents recent developments in the agriculture sector of Cambodia. Chapter three gives an overview of sectoral expenditure trends over the last decade. The budget process and its relationship to sectoral development strategies is discussed in chapter three. Chapter four discusses the novel contribution of the AgPER in analyzing the efficiency and effectiveness of government spending using benefit-cost analysis to examine select public investments. Chapter five discusses how likely climate change trends may affect future agriculture expenditures and suggests some priority areas for public spending. The conclusion section summarizes the major findings and policy recommendations of the report.

This thesis analyses position of the Czech transport system and its importance for Czech economy and society. Based on conducted analysis and derived findings, this thesis highlights current problems and imperfections that adversely affect our transport system. In particular, these three are found the most serious ones: a weak harmonization of terms of transport between rail and road transport, an insufficient modal share and a need of fast completion and modernization of motorways and dual carriageways. Author's recommendations for a swift remedy of current imperfections, which limit the Czech transport system in its development, are propounded in the last part of the thesis.

High volatility in the world prices of petroleum has been a characteristic feature of the global economy in the last decade. World petroleum prices increased four-fold between 2004 and 2008 and, and following a drop in prices in the second half of 2008, petroleum prices have been rising again, and they are several times higher than they were two decades ago. Since high and volatility of prices is likely to be a permanent feature of the global economy for the foreseeable future, they merit a reconsideration of the national transport and taxation policies that were put in place when fuel prices were not such a significant component of trade-related transactions costs in Sub-Saharan Africa (SSA) countries. Transport practices that were based on the assumption of low price of fuel are not sustainable, and policies neglect fuel efficiency considerations through lowering the fuel consumption of vehicles measures are no longer sustainable. Efficient and low transport cost is essential to achieve regional economic integration and strengthen Africa's competitiveness in external markets. Higher diesel prices also impact on the prices of all other goods which use diesel as an intermediate input. The most significant among them with implications for the poor in low-income developing countries is food, on which the poor spend a disproportionately high share of their total household expenditures. This report is in three parts in the first part, transport fuel prices in the countries of SSA are compared with those of other regions of the world. The comparison is not only in terms of the actual retail prices but also, but taking account of per capita incomes and truck revenues, also in terms of affordability. This Part also provides evidence of the make-up of transport fuel prices in SSA countries, as a first step in assessing how they can be dealt with. The second part provides new evidence of the impact of these high fuel prices on the export competiveness of a sample of six SSA countries. It also provides a shorter description of the results of a study of the impact of fuel prices on logistics costs in Central America, since so far there have not been any studies of the impact of high transport fuel prices on logistics and food costs in SSA countries. The third part deals with the ways in which the impact of high transport fuel prices can be addressed. Two main areas of action are described, those that would reduce the retail price of transport fuel and those that would increase fuel efficiency, so they impact of high prices would be reduced. This section focuses on diesel fuel, as this is by far the most used by the trucks that transport export products and are involved in domestic logistics. This section concludes with some ideas on what could be done next to make progress on implementing the most promising ideas for reducing the impact of high transport fuel prices.

V diplomski nalogi sem proučeval področje opravljanja transportnih storitev s pomočjo zunanjih izvajalcev ter ugotavljal smotrnost njihove vključitve v proces racionalizacije transporta na primeru podjetja Štore Steel d.o.o.. Omenjeno področje sem proučeval tako s teoretičnega, kot tudi s praktičnega vidika, kjer sem za podjetje Štore Steel d.o.o. predstavil analizo transportnih stroškov za obdobje od 01.01.2006 do 31.12.2008. Pri tem sem analiziral stroške, ki jih ima podjetje do zunanjih izvajalcev in stroške, ki bi jih podjetje imelo, če bi samo oziroma z lastnimi viri opravljalo transportne storitve. In my degree dissertation I studied the subject of provision of transport services, with some help from outside contractors and observed the functionality of their inclusion in the process of transport rationalization on the case of Štore Steel d.o.o., the best producer of flat spring steel in Europe and steel made to order for customers in market niches of automotive industry. The mentioned subject was studied from the theoretical as well as from the practical point of view, where I’ve presented an analysis of transport costs, which the company has to outside performers, and the costs, which the company would have, if they performed the transport service with their own sources.

The key subject of my thesis was costs of transport in a company. My goal was to analyze the way how a company set their price of transport as provided service. I tried to find the right height of costs of transport which would include all car costs and employee´s costs per hour in a company I chose on my own. Then I compared the correct costs of transport to the Value of Time. There is a huge amount of Value of Time studies available. The European approaches are more in line with congestion measurement and better transferable from one country to another as they reflect willingness-to-pay values rather than unit costs derived form macro-economic indicators. Finally the values of travel time saving proposed by the HEATCO project by country, mode, travel purpose and trip length. For comparison I used value of time recommended by institute HEATCO for business purposes. The result of my analysis showed that the company I chose doesn´t calculate the costs of transport in the correct way and the right height.So I suggest to change the way of calculating the price for transport from fix amount per kilometer to fix amount per hour. My solution would reflect the real costs of car, employee and time spent by travelling.

This paper provides an overview of the major current debates on infrastructure policy. It reviews the evidence on the macroeconomic significance of the sector in terms of growth and poverty alleviation. It also discusses the major institutional debates, including the relative comparative advantage of the public and the private sector in the various stages of infrastructure service delivery as well as the main options for changes in the role of government (i.e. regulation and decentralization).

This report is concerned with the development of the infrastructure which is required in order to support proposed mines in Southern Mongolia. In order for the mines to be developed, it will be necessary to provide towns for the new inhabitants, road and rail links to provide supplies and to transport the mines' products to markets, and electricity for the mines' operations. Water resources need to be investigated and supplied to the mines and towns. And as all of the development advances, consideration needs to be given to mitigating any negative environmental and social impacts. The geographic focus of the report varies according to the particular topic. The mines are all located in a region which this report defines as 'Southern Mongolia', and which includes the images of Omnogovi, Dornogovi, Govisumber and Dundgovi. The majority of the important new mines are located in Omnogovi, and the analysis of housing and social impacts is concentrated in areas close to these mines. In terms of time, the report concentrates on the most important priorities for government action up to 2015. Nevertheless, consideration is given to a longer time-horizon when considering the potential environmental and water resource demands likely to arise as a result of the region's development. The report is not concerned with the longer-term actions required for broader economic development of the region, including the development of value-added industries associated with the mining industry. To get to long-term objectives, it is necessary to start with the short term. This report assumes that the Government will permit development of the mines in the near future.

Over the past four decades Africa has diverged from other developing regions and is now the poorest region in the world. This paper offers an explanation of Africa's slow growth in terms of its distinctive economic and human geography: its high dependence upon natural resource exports, the many landlocked countries, and the high ethnic diversity of the typical state. It discusses how key economic policy choices, especially trade and fiscal policy, and assistance from the international community, need to tailored specifically to these distinctive circumstances. Part one of this paper sets out an explanation for why this happened and whether it is likely to recur, using the building blocks of economic geography. Africa is distinctive both in its physical geography and its human geography and these have shaped its opportunities. Part one has three sections. Section two considers the implications of Africa's distinctive physical geography. It accounts for some of Africa's slow growth and suggests how strategies will need to differ radically among Africa's countries. In section three author turn to its distinctive human geography and the political problems that this has created. To a considerable extent these problems recently have been surmounted: Africa's human geography may explain delayed take-off rather than predict persistent stagnation. Finally, in section four, author consider three interactions between physical geography and human geography that generate intractable problems that are likely to require both regional action and international assistance in various forms. Part two uses the analysis of part one to consider policy options. Section five discusses options for African governments. Section six focuses on the supporting actions that can be taken by governments outside Africa and by international agencies. Section seven offers a brief conclusion.

The purpose of this article was to discuss cost parameters for the milk collection freight, based in the theoretical principles of scale economies and distance. Such study is justified for the difficulties to measure the parameters which might help in the management of the fleets, relating to the case of milk transportation. The costs related to different kinds of vehicle were estimated, through cost spreadsheets developed by the pattern support system and also the parameters of fleet efficiency related to Economies of scale, and distance for transportation. It was evidenced economy in favor of the vehicles with major transport capacity; such evidences could direct the table negotiations of freights, signaling for the preference for the use of this type of vehicle of greater capacity and better performance, according to evaluated parameters.
