Foreign Exchange Rationing and Wheat Markets in Ethiopia
In spite of remarkable growth in Ethiopia’s agricultural production and overall real incomes (GDP/capita) from 2004/05 to 2008/09, prices of major cereals (teff, maize, wheat and sorghum) have fluctuated sharply in both nominal and real terms. International prices of cereals also fluctuated widely, particularly between 2006 and 2008. However, the links between Ethiopia’s domestic cereal markets and the international market are by no means straightforward. Among the major staples, only wheat is imported or exported on a significant scale. And frequent changes in trade and macro-economic policies, movements in international prices and fluctuations in domestic production have at times eliminated incentives for private sector imports of wheat.From July 2005 to March 2007, private sector wheat imports were profitable and domestic wheat prices closely tracked import parity prices. Then, from April 2007 to May 2008, good domestic harvests coincided with increase international wheat prices, so private sector wheat imports were no longer profitable. Most recently, rationing of foreign exchange for imports effectively stopped private sector wheat imports beginning in about April 2008. Partial equilibrium analysis shows, however, that government imports and sales in 2008-09 effectively increased domestic supply and lowered market wheat prices. These sales at the low official price also implied that recipient households, traders and flour mills enjoyed a significant subsidy. Allowing the private sector access to foreign exchange for wheat imports or auctioning government wheat imports in domestic markets would eliminate these rents and generate additional government revenue, while having the same effect on market prices as government subsidized sales.Keywords: Exchange Rate Policy, Agricultural Trade, Price Stabilization, Food Polic

Rice markets in Madagascar in disarray : Policy options for increased efficiency and price stabilization. Washington, World Bank.
Faced with a production shortfall in early 2004 and a sharp rise in the price of imported rice due to a depreciation of the Malagasy franc and a spike in international rice prices, Madagascar attempted to stabilize domestic rice prices through public tenders for rice imports and subsidized sales at official prices. This paper discusses the 2004 rice crisis, chronicling the events that triggered the crisis and the subsequent interventions by the government, and analyzes the impacts of the policies adopted and steps taken to spur development of the domestic rice market. Using a partial equilibrium model, the paper also quantifies the overall costs and benefits of a change in import duties for various household groups, and compares this intervention to a policy of targeted food transfers or security stocks. as well as other options for price stabilization, including a reduction in import duties and a security stock policy

Страхування туристичної діяльності в Україні
At present, tourism insurance is in high demand in Ukraine, as there has been a big tendency in recent years to increase the number of people traveling abroad. The reason for such growth in the tourism sector is primarily due to a change in the way of life of Ukrainian citizens, the adoption of a visa-free regime, adequate prices for rest and quality of service provision in comparison with domestic ones. The modern insurance market offers a large assortment of insurance products, which enables it to integrate with other sectors of the economy. Tourist activity in its economic nature is characterized by a high degree of riskiness, and therefore its effective functioning is impossible without insurance. All developed countries have long introduced insurance in the tourist market for the successful functioning of this industry and the state economy as a whole. The issue of insurance in tourism in the Ukrainian market is problematic, as it is characterized by low awareness and trust in the population, insufficient attention from the state authorities. Insurance and tourism are of great importance for the development of the economy. The growth of the dynamics of international tourist flows requires the strengthening of the quality requirements of tourist services and the existence of the insurance market. Insurance of tourism industry is a new type of insurance in Ukraine, the study and analysis of the problems of this type of insurance is not perfect and little studied by domestic scientists, in contrast to foreign ones. The tourism industry always has a certain danger to the life of both tourists and its employees. Natural disasters, accidents and other unforeseen events can affect the balanced activities of the tourist complex. After all, with the development of scientific and technological progress, the natural and industrial-economic cataclysms are not decreasing, but on the contrary increasing. In order to ensure the stable operation of travel companies and to ensure quality recreation for tourists in various areas of high risk, there are various risk management tools, one of which is insurance. Insurance as a component of the security system in the tourism industry helps to stabilize the activity of tourism enterprises and tour operator companies, as well as safety of tourist trips both in Ukraine and abroad.В теперішній час в Україні користується великим попитом туристичне страхування, адже за останні роки спостерігається велика тенденція збільшення кількості осіб, які подорожують за кордон. Причина такого росту у сфері туризму в першу чергу пов’язана із зміною способу життя українських громадян, прийняттям безвізового режиму, адекватними цінами на відпочинок та якістю надання послуг в порівнянні з вітчизняними. Сучасний ринок страхування пропонує великий асортимент страхових продуктів, завдяки яким він має можливість інтегруватися з іншими галузями економіки. Туристична діяльність за своєю економічною природою характеризується високим ступенем ризиковості, а тому її ефективне функціонування неможливе без страхування. Усі розвинуті країни вже давно запроваджують страхування на туристичному ринку для успішного функціонування даної галузі та державної економіки в цілому. Питання страхування в туризмі на українському ринку є проблемним, оскільки відрізняється низькою проінформованістю та довірою населення, недостатньою увагою з боку державних органів. Страхування і сфера туризму мають велике значення для розвитку економіки. Зростання динаміки міжнародних туристичних потоків вимагає посилення вимог якості туристичних послуг та існування страхового ринку. Cтрахування туристичної галузі – це новий вид страхування в Україні, то вивчення і аналіз проблематики такого виду страхування не є досконалим і мало вивчений вітчизняними науковцями, на відміну від зарубіжних. Туристична галузь завжди несе в собі певну небезпеку для життєдіяльності як самих туристів, так і її працівників. Стихійні лиха, нещасні випадки та інші непередбачені події можуть порушити збалансовану діяльність туристичного комплексу. Адже з розвитком науково-технічного прогресу природні і виробничо-господарські катаклізми не зменшуються а навпаки збільшуються. Для забезпечення стабільної діяльності туристичних компаній та гарантування якісного відпочинку туристам, у різних сферах підвищеного ризику, існують різні інструменти управління ризиком, одним з яких є страхування. Страхування як складова системи безпеки в туристичній індустрії сприяє стабілізації діяльності туристичних підприємств та туроператорських фірм, а також безпеці туристичних подорожей як в Україні, так і за її межами
Digital Transformation and Innovation in Business: the Impact of Strategic Alliances and Their Success Factors
The purpose of the article is to reveal the scientific approach that substantiates the impact of the creation of strategic alliances (SA) on the digital transformation of business and the development of their innovative power based on identified success factors. The aim was achieved using the following methods: abstract logic and typification (for classification of SA's success factors), generalization (to determine the peculiarities of SA's influence on their innovation development), analytical and ranking method (to determine the relationship between the dynamics creating of SA and the degree of acceleration of digital transformation), expert evaluation (to determine the degree of influence of SA success factors by business areas). Implementing a business-integrated approach to understanding digital transformation will accelerate implementation of innovation and organizational change, identifies future prospects for market, customer and business relationships, highlighting the importance of researching the factors that ensure their success. An alternative vision of SA’s success factors is suggested, which are determined by the possibilities the organization of partnerships and organizational culture, integration of business sectors, compatibility of management goals, external relevance, obtaining synergies. Innovation is considered by the authors as an integration factor that reconciles all groups of SA success factors, giving them the necessary focus to solve business problems. The results of the study show that the creation of SA has a significant impact on accelerating and changes priority of digital transformation of business areas involved in strategic partnerships, and the impact of SA on the development of their innovation power is crucial
Theoretical description of adiabatic laser alignment and mixed-field orientation: the need for a non-adiabatic model
We present a theoretical study of recent laser-alignment and
mixed-field-orientation experiments of asymmetric top molecules. In these
experiments, pendular states were created using linearly polarized strong ac
electric fields from pulsed lasers in combination with weak electrostatic
fields. We compare the outcome of our calculations with experimental results
obtained for the prototypical large molecule benzonitrile (CHN) [J.L.
Hansen et al, Phys. Rev. A, 83, 023406 (2011)] and explore the directional
properties of the molecular ensemble for several field configurations, i.e.,
for various field strengths and angles between ac and dc fields. For
perpendicular fields one obtains pure alignment, which is well reproduced by
the simulations. For tilted fields, we show that a fully adiabatic description
of the process does not reproduce the experimentally observed orientation, and
it is mandatory to use a diabatic model for population transfer between
rotational states. We develop such a model and compare its outcome to the
experimental data confirming the importance of non-adiabatic processes in the
field-dressed molecular dynamics.Comment: 11 pages, 9 figure
Factors that transformed maize productivity in Ethiopia
Published online: 26 July 2015Maize became increasingly important in the food
security of Ethiopia following the major drought and famine
that occurred in 1984. More than 9 million smallholder house-
holds, more than for any other crop in the country, grow maize
in Ethiopia at present. Ethiopia has doubled its maize produc-
tivity and production in less than two decades. The yield,
currently estimated at >3 metric tons/ha, is the second highest
in Sub-Saharan Africa, after South Africa; yield gains for
Ethiopia grew at an annual rate of 68 kg/ha between 1990
and 2013, only second to South Africa and greater than
Mexico, China, or India. The maize area covered by improved
varieties in Ethiopia grew from 14 % in 2004 to 40 % in 2013,
and the application rate of mineral fertilizers from 16 to 34 kg/
ha during the same period. Ethiopia
’
s extension worker to
farmer ratio is 1:476, compared to 1:1000 for Kenya, 1:1603
for Malawi and 1:2500 for Tanzania. Increased use of im-
proved maize varieties and mineral fertilizers, coupled with
increased extension services and the absence of devastating
droughts are the key factors promoting the accelerated growth
in maize productivity in Ethiopia. Ethiopia took a homegrown
solutions approach to the research and development of its
maize and other commodities. The lesson from Ethiopia
’
s
experience with maize is that sustained investment in agricul-
tural research and development and policy support by the
national government are crucial for continued growth of
