The Impact of Microfinance Services on the Living Conditions of Households with Low Income Earning: The Case of Addis Ababa
Creators: name: Gebremedhin, Bereket
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2008

description: Ethiopia is one of the least developed countries with high incidence of poverty. Poverty reduction has been the center of development strategy in the country. Microfinance program on the other hand have been accepted as instruments in fighting against poverty through out the world. Since 1996, Microfinance institutions (MFIs) in Ethiopia have been developed both in size and program out reaches. Currently there are 27 MFIs in the country. Despite of its expansion, little is known about the impact of the program in changing the life of the low income households. The study therefore, tries to fill some of this gap by taking Addis Ababa as a case study. To meet the objective of the study, both primary and secondary data were used. For the primary data, two kebeles from Addis Kifle Ketema were selected. 200 households were interviewed using random sampling. For data analysis, descriptive statistical and econometric model were adopted both for the entire sample and for various income groups. The study indicates that microfinance improves low income earning households' economic status. Households' income, expenditure and asset are improved as a result of program participation. But the result is not uniform for various income groups. For relatively better-off households the impact is comparatively high in expenditure, whereas for low income households the impact is highly explained in terms of increase in household asset this would imply that the relative success of the program depends on the amount of the loan and its utilization. Moreover, in this study there is evidence that microfinance improves the non economic dimension of poverty. It improves social acceptance and decision making of women. But, the result also indicates that credit alone does not improve the status of the poor if it is not substantiated by other technical supports that help the low income households to cope up with short term problems and enabling them better competitive in the long run.
Construction and stability of blowup solutions for a non-variational semilinear parabolic system

description: We consider the following parabolic system whose nonlinearity has no gradient structure: $$\left\{\begin{array}{ll} \partial_t u = Δu + |v|^{p-1}v, \quad & \partial_t v = μΔv + |u|^{q - 1}u,\\ u(\cdot, 0) = u_0, \quad & v(\cdot, 0) = v_0, \end{array}\right. $$ in the whole space $\mathbb{R}^N$, where $p, q > 1$ and $μ> 0$. We show the existence of initial data such that the corresponding solution to this system blows up in finite time $T(u_0, v_0)$ simultaneously in $u$ and $v$ only at one blowup point $a$, according to the following asymptotic dynamics: $$\left\{\begin{array}{c} u(x,t)\sim Γ\left[(T-t) \left(1 + \dfrac{b|x-a|^2}{(T-t)|\log (T-t)|}\right)\right]^{-\frac{(p + 1)}{pq - 1}},\\ v(x,t)\sim γ\left[(T-t) \left(1 + \dfrac{b|x-a|^2}{(T-t)|\log (T-t)|}\right)\right]^{-\frac{(q + 1)}{pq - 1}}, \end{array}\right.$$ with $b = b(p,q,μ) > 0$ and $(Γ, γ) = (Γ(p,q), γ(p,q))$. The construction relies on the reduction of the problem to a finite dimensional one and a topological argument based on the index theory to conclude. Two major difficulties arise in the proof: the linearized operator around the profile is not self-adjoint even in the case $μ= 1$; and the fact that the case $μ\ne 1$ breaks any symmetry in the problem. In the last section, through a geometrical interpretation of quantities of blowup parameters whose dimension is equal to the dimension of the finite dimensional problem, we are able to show the stability of these blowup behaviors with respect to perturbations in initial data.

The Impact of Real Effective Exchange Rate on Trade Balance in Ethiopia
Creators: name: Tesema, Temesgen
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: In the era of globalization, global macroeconomic crises and the changes in the international trade pattern have accentuated the need for clearer understanding of the factors underlying a country's balance of trade position. In this onset, this paper examines the short run and long run effect of real effective exchange rate on trade balance of Ethiopia together with other variables that assumed to have effect on trade balance such as real GDP, government consumption, money supply and trade openness. The Autoregressive Distributed Lag (ARDL) Approach is used for analysis time serious annual data of period 1979/80 to 2013/34. Different diagnostic tests are under taken to check this time series data consistency and stability of selected model. As econometrics result reveals that these macro economic variables have short run as well as long run positive and significant effect on trade balance of the country except money supply, which has negative effect in the short run. That is in the short run real GDP , real exchange rate, government expenditure and trade openness have positive effect on trade balance of the country, while money supply has negative effects. Where as in the long run: real GDP, real effective exchange rate, money supply, government consumption and trade openness have significant and positive effect on trade balance. Based on the result I conclude that real effective exchange rate has short as well as long run effect on trade balance. To handle this series effect and reduce this continual deficit on trade balance government have to formulate strong controlling mechanism on monitory policy and trade structure of the country.

title: Bugs Buy Steady Releases from Hydropower Producers to Encourage More Synergistic Reservoir Management
Creators: name: Rind, Moazzam Ali
Publisher: name: Utah State University
Year: 2022

description: Hydropower generated from dams has significant economic value, however, that value is achieved at the cost of native ecosystem devastation. Here, we have estimated loss in hydropower revenue due to inclusion of the steady low flow days –Bug Flow Experiments. We developed a linear optimization model and constraint method that restrict the number of steady low flow days while maximizes the hydropower revenue generation. The results suggested that increase in release volume will benefit both the objectives (win-win scenario), energy price differential between on-and off-peak periods controls the position and shape of tradeoff curves, and offset release does not have impact on the tradeoffs. Monthly results of the model helped us devise a program where hydropower producers are compensated for the steady low flow days. The program allocates funds and provides opportunities for ecosystem managers to pay hydropower producers revenue loss from the steady low flow days (escape from the win-lose scenario). In other words, the ecosystem managers are empowered to make decision about when and how many steady low flows days to buy against compensating the hydropower producers. This study is an initial effort and next steps would include a) improve results by adding information from the GTMax SL model used by the Western Area Power Authority and b) engagement with more organizations: National Park Service, Bureau of Reclamation, and Glen Canyon Dam Adaptive Management program.
title: Extensions to the Syrjala Test with Eye-Tracking Data Analysis Applications in R
Creators: name: McKinney, Eric D.
Publisher: name: Utah State University
Year: 2022

description: Eye tracking is a process for measuring the movement of an individual’s eye(s) when that individual is looking at something. Many eye-tracking technologies exist to aid in calculating and recording data associated with what a person focuses their visual attention on. For example, eye-tracking technology can record points on an image that a person is looking at. Often the question arises as to whether two people, or groups of people, are looking at the same thing(s). This dissertation presents a new way (or test) to quantify those differences while taking into consideration the randomness associated with such data. Hence, the test can help to determine if the differences between what the two people, or groups of people, are looking at are caused by chance or not. However, the test is also useful to many other kinds of data similar to but outside of eye-tracking research. While this test takes longer for standard household computers to run than other alternative tests currently available, it is shown to be better in many cases at correctly identifying differences when those differences were not caused by randomness. The test is also better at identifying when the differences are caused by chance, and not necessarily by the people. The test is applied to eye-tracking data from a study held at Utah State University (USU), called the USU Posture Study, where many differences are found. The test is available online, and comes with a user manual and some examples of how to use it.
title: Parent Work-Family Balance and Adolescent Psychosocial Well-Being During the COVID-19 Shutdown
Creators: name: Woodward, Shailey
Publisher: name: Utah State University
Year: 2022

description: Parents who work have many responsibilities to fulfill. They may encounter frustration and exhaustion, which can impact how well they parent. Experiences such as financial strain and the COVID-19 shutdown may further impact parenting. At the same time, adolescents are establishing identities and need attentive parents to help them develop healthy psychosocial well-being. Using Erikson’s (1968) psychosocial theory of development as a backdrop, the purpose of this study was to observe the relationships between parent work-family balance, parenting satisfaction, and adolescent psychosocial well-being within the context of financial stress and the COVID-19 shutdown. I found that parent and adolescent perceptions about the parent’s work-family balance and parenting satisfaction are moderately to strongly correlated. I also found parents’ positive perceptions about their work-family balance and parenting satisfaction related to higher reported adolescent cognitive autonomy and self-esteem. However, when parents’ work interrupted home life, adolescents reported lower emotional autonomy. Parents experiencing financial strain reported more negative perceptions of their ability to balance work and family. And parents who had a worse experience balancing work and family during the COVID-19 shutdown were less satisfied with their parenting. It is important that parents attend to their own needs to better meet the needs of their child.
title: Evaluating Microbial Safety of Food Products and Processes in Small Scale Food Services, Processors and Manufacturers
Creators: name: Acharya, Sujan
Publisher: name: Utah State University
Year: 2022

description: This study evaluated microbial safety of relatively new and modified food products prepared especially by small-scale foodservice establishments and home producers. In the first part, microbial safety during fermentation at room temperature was evaluated. Chapter 3 monitored Listeria monocytogenes and Escherichia coli O157 survival during Sauerkraut’s natural fermentation. Chapter 4 evaluated the survival of acid-adapted E.coli O157 during kombucha fermentation and in kombucha-fruit blend during refrigeration. During both fermentations, the pathogens were inactivated before the recommended duration of fermentation. However, E.coli O157 introduced after fermentation survived in kombucha-fruit blends during refrigerated storage. The second part (Chapter 5) evaluated the safety of commercial and lab-prepared fry sauce by monitoring the survival of acid-adapted E. coli O157, L. monocytogenes, and Salmonella at room temperature and refrigerated storage. The pathogens survived longer under refrigeration in the treatments in comparison to storage at room temperature. Inverse relationship of pH and pathogen reduction were observed more prominently at refrigerated storage. The third part (Chapter 6) assessed the survival of L. monocytogenes in commercial cold-brewed coffee under refrigeration. 18 ready-to-drink and concentrate samples were monitored for the survival of inoculated L. monocytogenes for 60d. The pathogen was undetectable within 60 d in 10 samples, whereas the pathogen survived in the remaining 8 samples. The last part of the study (Chapter 7) assessed the survival of E. coli O157, L. monocytogenes, and Salmonella in 10, 20, 30, 40, and 50% ethanol and juice mixtures at ambient temperature for 48 h. The pathogens did not survive in the mixture of juice and ethanol at 40 or 50% after 48 hours. In the mixtures prepared with 10-30% ethanol and juice, the decrease in pathogen was variable between the pathogen itself and the juice evaluated, with some demonstrating survival after 48 h. The study's finding does not imply that the products evaluated in this study and other similar products can be made without individual product evaluation.

description: Various theories that aim at unifying gravity with quantum mechanics suggest modifications of the Heisenberg algebra for position and momentum. From the perspective of quantum mechanics, such modifications lead to new uncertainty relations which are thought (but not proven) to imply the existence of a minimal observable length. Here we prove this statement in a framework of sufficient physical and structural assumptions. Moreover, we present a general method that allows to formulate optimal and state-independent variance-based uncertainty relations. In addition, instead of variances, we make use of entropies as a measure of uncertainty and provide uncertainty relations in terms of min- and Shannon entropies. We compute the corresponding entropic minimal lengths and find that the minimal length in terms of min-entropy is exactly one bit.

description: Non-anticommutative deformations have been studied in the context of supersymmetry (SUSY) in three and four space-time dimensions, and the general picture is that highly nontrivial to deform supersymmetry in a way that still preserves some of its important properties, both at the formal algebraic level (e.g., preserving the associativity of the deformed theory) as well as at the physical level (e.g., maintaining renormalizability). The Hopf algebra formalism allows the definition of algebraically consistent deformations of SUSY, but this algebraic consistency does not guarantee that physical models build upon these structures will be consistent from the physical point of view. We will investigate a deformation induced by a Drinfel'd twist of the ${\cal N}=1$ SUSY algebra in three space-time dimensions. The use of the Hopf algebra formalism allows the construction of deformed ${\cal N}=1$ SUSY algebras that should still preserve a deformed version of supersymmetry. We will construct the simplest deformed version of the Wess-Zumino model in this context, but we will show that despite the consistent algebraic structure, the model in question is not invariant under SUSY transformation and is not renormalizable. We will comment on the relation of these results with previous ones discussed in the literature regarding similar four-dimensional constructions.

description: We consider soft random geometric graphs, constructed by distributing points (nodes) randomly according to a Poisson Point Process, and forming links between pairs of nodes with a probability that depends on their mutual distance, the "connection function." Each node has a probability of being isolated depending on the locations of the other nodes; we give analytic expressions for the distribution of isolation probabilities. Keeping the node locations fixed, the links break and reform over time, making a dynamic network; this is a good model of a wireless ad-hoc network with communication channels undergoing rapid fading. We use the above isolation probabilities to investigate the distribution of the time to transmit information to all the nodes, finding good agreement with numerics.

Year: 2022

description: O presente trabalho trata de uma das etapas de desenvolvimento do jogo digital Tétrico – releitura do clássico Tetris, de Alexey Pajitnov. Tétrico é um jogo que traz peças tétrades formadas por fisionomias cartunizadas e, através de uma série de analogias, constitui uma metáfora que aborda o momento pandêmico a partir de uma concepção da gamearte. Na medida em que o Tétrico substitui as formas geométricas das peças do Tetris por fisionomias desenhadas que se acumulam, busca-se trazer à tona os efeitos e dinâmicas da aglomeração. No ano de 2021, dois protótipos do jogo foram desenvolvidos e ambos foram apresentados para um grupo focal de jogadores, sendo essa experiência registrada em um diário de bordo. Parte de uma pesquisa maior sobre processos de criação, o recorte proposto consiste em analisar o instrumento diário de bordo no processo de desenvolvimento do jogo, levando em conta as considerações dos jogadores, feitas durante essa fase de teste do protótipo. Buscamos apresentar, a partir dos registros produzidos, as limitações identificadas e as possibilidades estéticas e conceituais sugeridas. Assim, há o objetivo de destacar a importância do diário de bordo nos processos intermediários de desenvolvimento, entre o protótipo e a versão final do jogo Tétrico. Os autores que subsidiam a discussão aqui desenvolvida são: Ascott (2003), Brown (2020), McLuhan (2005), Mendonça (2014), Varella (2020), Brown (2020) e Saul & Stuckey (2007).

description: In the cosmological scenario in $f\left( T\right) $ gravity, we find analytical solutions for an isotropic and homogeneous universe containing a dust fluid and radiation and for an empty anisotropic Bianchi I universe. The method that we apply is that of movable singularities of differential equations. For the isotropic universe, the solutions are expressed in terms of a Laurent expansion, while for the anisotropic universe we find a family of exact Kasner-like solutions in vacuum. Finally, we discuss when a nonlinear $f\left( T\right) $-gravity theory provides solutions for the teleparallel equivalence of general relativity and derive conditions for exact solutions of general relativity to solve the field equations of an $f(T)$ theory.

Public Infrastructure Investment, Private Investment and Economic Growth in Ethiopia: Co-Integrated VAR Approach
Creators: name: Alemnew, Teklebirhan
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: This study investigates the relationship between private investment and public infrastructure investment, as well as their relative impact on economic growth in Ethiopia. Moreover, the study carried out through analyzing the impact of the two broad categories of public infrastructure investments: physical and social. In order to achieve the stated objective the private investment and the growth model were estimated separately using cointegrated VAR approach for the period 1974/75-2013/14. The study reveals that physical public infrastructure investment has a crowding-in effect on private investment both in the short run and long-run. On the other hand, social public infrastructure investment is found to deleteriously impacted private investment in the long run while in the short-run it has insignificant impact, implying that the crowding out impact of social public infrastructure investment have been large enough to offset any crowding-in effects in the long-run. Moreover, the study shows the significant and positive impact of output growth in stimulating private investment both in the short-run and long-run. The contribution of physical public infrastructure investment to the real GDP is positive and significant in the long-run while it has a significant negative impact in the short run. In the long run, social public infrastructure investment exerts negative and significant effect on economic growth while in the short run it has insignificant impact. Finally, as a policy implication, it will be natural to think of supplementary reforms so as to tackle the negative impact of social public infrastructure investment on private investment and economic growth.

description: We demonstrate that light is subject to anomalous (i.e., negative) diffraction when propagating in the presence of hyperbolic dispersion. We show that light propagation in hyperbolic media resembles the dynamics of a quantum particle of negative mass moving in a two-dimensional potential. The negative effective mass implies time reversal if the medium is homogeneous. Such property paves the way to diffraction compensation, spatial analogue of dispersion compensating fibers in the temporal domain. At variance with materials exhibiting standard elliptic dispersion, in inhomogeneous hyperbolic materials light waves are pulled towards regions with a lower refractive index. In the presence of a Kerr-like optical response, bright (dark) solitons are supported by a negative (positive) nonlinearity.

The Socio-Economic Impact of Intellectual Property Rights Regime of Ethiopia
Creators: name: Hailemariam, Teklay
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: Intellectual property rights are believed to have direct role in facilitating the development efforts of a particular country by encouraging investment in inventions and by establishing secured property system. The now advanced countries and the newly industrialized countries used to design their IPRs laws in tune with their technical and economic needs. They do so, by violating foreign rights, by using petty-patents and encouraging imitation, adaptation and reverse-engineering. However, means available during those times are blocked by harmonization of intellectual property rights through multilateral, regional and bilateral agreements. There are also ongoing harmonization efforts. The flexibilities for policy options are impoverished by these movements. Catching up efforts by technologically non-proficient or non-industrialized countries is becoming increasingly difficult. Their low technological capability demands them to tailor intellectual property system that helps technological knowledge develop within them by encouraging learning by doing and accumulation of knowledge. Compared to the historical, theoretical and empirical lessons, the current Ethiopian intellectual property laws, are aiming to encourage local inventive activities, build national technological capability and transfer and adaptation of foreign technologies by domestic enterprises. Ethiopia should, therefore, strongly implement its IPRs laws in a way that can contribute to its development efforts and enhance technical learning and accumulation of knowledge by domestic enterprises via increased exposure to foreign technologies. In brief Ethiopia should consider the intellectual property rights immense role of Innovation and Creativity in development • Key to development in today's knowledge economy prosperity & sustainability of a country & its development is no longer based on natural resources but on intangible assets such as innovations and creative works essential tool to enhance competitiveness and ensure market leadership v • Innovation and creative works are valuable assets. Significance of assets can be seen by looking at: the change in indicators of wealth share of intangibles in company's assets and The growth in international trade Contributing Factors for an effective Innovation System are: The amount of financial resources that companies and the government allocate to Research and Development activities • The financial system is a key feature of the general investment climate and is particularly important for the creation of new firms. • The availability of Microfinance and for financing of more risky but potentially innovative enterprises is key. The availability of Skilled man power in the country /Human Capital /Human Capital provides the perhaps most important pillar for a dynamic innovation system.

description: The importance of electron-hole interband interactions is widely acknowledged for iron-pnictide superconductors with high transition temperatures (Tc). However, high-Tc superconductivity without hole carriers has been suggested in FeSe single-layer films and intercalated iron-selenides, raising a fundamental question whether iron pnictides and chalcogenides have different pairing mechanisms. Here, we study the properties of electronic structure in the high-Tc phase induced by pressure in bulk FeSe from magneto-transport measurements and first-principles calculations. With increasing pressure, the low-Tc superconducting phase transforms into high-Tc phase, where we find the normal-state Hall resistivity changes sign from negative to positive, demonstrating dominant hole carriers in striking contrast to other FeSe-derived high-Tc systems. Moreover, the Hall coefficient is remarkably enlarged and the magnetoresistance exhibits anomalous scaling behaviors, evidencing strongly enhanced interband spin fluctuations in the high-Tc phase. These results in FeSe highlight similarities with high-Tc phases of iron pnictides, constituting a step toward a unified understanding of iron-based superconductivity.

The Determinants of Economic Growth in Ethiopia: A Time Series Analysis
Creators: name: Gebru, Tewodros
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The main objective of this study is to investigate the determinants of economic growth in Ethiopia during the period 1974-2013. The Autoregressive Distributed Lag (ARDL) Approach to Co-integration and Error Correction Model are applied in order to investigate the long-run and short run relationship between the dependent variable (real GDP) and its determinants. The finding of the Bounds test shows that there is a stable long run relationship between real GDP, Physical capital, human capital, export, aid, external debt and inflation. The empirical results reveal that both physical capital and human capital are found to have positive impact on economic growth while debt affects economic growth negatively and statically significant at 1 percent. However, the study found out that export of goods and service, foreign aid and inflation have statistically insignificant impact on economic growth in the long run. This study has also an important policy implication. The findings of this study imply that economic growth can be improved significantly when the physical capital and human capital increases. Hence policy makers and /or the government should strive to increase capital formation (investment) which is believed as a back bone of growth and has allocate adequate finance for human capital, which will help to work on quality of education and providing basic health services to the society. In addition to its effort, there should be a close monitoring and consistent debt management strategies, which is used to avoid misallocation and mismanagement of external debt problem.

description: We report a detailed simulation and classical density functional theory study of the drying transition in a realistic model fluid at a smooth substrate. This transition (in which the contact angle $θ\to 180^\circ$) is shown to be critical for both short ranged and long-ranged substrate-fluid interaction potentials. In the latter case critical drying occurs at exactly zero attractive substrate strength. This observation permits the accurate elucidation of the character of the transition via a finite-size scaling analysis of the density probability function. We find that the critical exponent $ν_\parallel$ that controls the parallel correlation length, i.e. the extent of vapor bubbles at the wall, is over twice as large as predicted by mean field and renormalization group calculations. We suggest a reason for the discrepancy. Our findings shed new light on fluctuation phenomena in fluids near hydrophobic and solvophobic interfaces.

description: The nuclear reaction network is usually studied via precise calculation of differential equation sets, and much research interest has been focused on the characteristics of nuclides, such as half-life and size limit. In this paper, however, we adopt the methods from both multilayer and reaction networks, and obtain a distinctive view by mapping all the nuclear reactions in JINA REACLIB database into a directed network with 4 layers: neutron, proton, $^4$He and the remainder. The layer names correspond to reaction types decided by the currency particles consumed. This combined approach reveals that, in the remainder layer, the $β$-stability has high correlation with node degree difference and overlapping coefficient. Moreover, when reaction rates are considered as node strength, we find that, at lower temperatures, nuclide half-life scales reciprocally with its out-strength. The connection between physical properties and topological characteristics may help to explore the boundary of the nuclide chart.

description: We present a technique for separating nuclear double beta decay ($ββ$-decay) events from background neutrino interactions due to $^{8}$B decays in the sun. This background becomes dominant in a kiloton-scale liquid-scintillator detector deep underground and is usually considered as irreducible due to an overlap in deposited energy with the signal. However, electrons from 0$νββ$-decay often exceed the Cherenkov threshold in liquid scintillator, producing photons that are prompt and correlated in direction with the initial electron direction. The use of large-area fast photodetectors allows some separation of these prompt photons from delayed isotropic scintillation light and, thus, the possibility of reconstructing the event topology. Using a simulation of a 6.5~m radius liquid scintillator detector with 100~ps resolution photodetectors, we show that a spherical harmonics analysis of early-arrival light can discriminate between 0$νββ$-decay signal and $^{8}$B solar neutrino background events on a statistical basis. Good separation will require the development of a slow scintillator with a 5 nsec risetime.
Entropy of Reissner-Nordström-de Sitter black hole

description: Based on the consideration that the black hole horizon and the cosmological horizon of Reissner-Nordström black hole in de Sitter space are not independent each other, we conjecture the total entropy of the system should have an extra term contributed from the entanglement between the two horizons, except for the sum of the two horizon entropies. Making use of the globally effective first law and the effective thermodynamic quantities, we derive the total entropy and find that it will diverge as the two horizons tends to coincide.

Import Substitution in the Construction Sector: The Case of Selected Building Materials
Creators: name: Bisrat, Martha
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: This study investigates the domestic production, import and demand of cement, steel products and aluminum products. It assesses the foreign exchange spent for these materials, their import share and whether or not import substitution exists. Finally it predicts the import and demand for the next ten years and gives recommendations. The major data source used for this study comes from Central Statistic Agency and Ethiopian Custom Authority. The study finds that the import share of all three categories of products is insignificant. Import substitution is only seen for steel products and almost all of the demand for cement and steel products of the country is fulfilled by domestic production, whereas all the demand of aluminum product is fulfilled using import. The foreign exchange spent for all three products is high, reaches 72 billion Dollars for the year 2001/02 Ethiopian Calendar. The conclusions drawn from this study is that, as almost all the demand for cement and steel are satisfied using domestic production, this will be advantageous for the country to shift, only with a little more extended effort, in exporting these materials. From other countries experience it is believed that import substitution with export promotion would result in successful development policy. The prediction shows that 121,406 billion Birr will be needed to import all three categories of products for the next ten years. Hence, it will be a great achievement to save this huge sum of money using import substitution.
Biotechnology under the WTO: balancing free trade and biosafety

description: Biotechnology is sometimes regarded as a panacea for modern-day challenges, such as feeding a growing world population. Trading biotech products can offer significant economic opportunities, while also presenting risks of significant harm to human health and the environment (ie, biosafety). These risks and benefits are characterised by a range of uncertainties. Trading biotech products magnifies these risks and benefits globally. The World Trade Organization (WTO) is responsible for trade rules covering much of the world and resolving trade disputes between its member states. To enhance free trade and, at the same time, ensure biosafety, it is critically important that WTO judicial bodies strike a reasoned balance between trade and non-trade values. This requires decision-makers to balance the interests in trading biotechnology with those of ensuring biosafety, under conditions of uncertainty. This thesis examines how WTO judicial bodies attempt to achieve such a balance. In so doing, it explores the extent to which proportionality analysis and the precautionary principle can assist in balancing biosafety and free trade in biotech products. This study identifies epistemic issues stemming from the uncertainties surrounding the international trade of biotech products. It also reveals normative lacunae in the existing regulation of biotechnology under the WTO framework, along with weaknesses in the judicial examination of biotechnology legal disputes. This thesis offers insights into how WTO law could better achieve a balance between trade interests and biosafety and effectively pursue the goal of sustainable development. It does so by providing suggestions to fill several gaps left by WTO law, and by demonstrating that proportionality analysis and the precautionary principle can be appropriate criteria for determining the justifiability and the justification of biosafety measures in trade contexts.
Access to Credit and the Impact of Credit constraints on Agricultural Productivity in Ethiopia: Evidence from Selected Zones of Rural Amhara

description: The economy of Ethiopia is characterized by its reliance on subsistence agriculture and the existence of underdeveloped financial institutions, especially in rural areas. In the literature, the role of credit as an instrument to boost productivity and welfare has long been justified. The main goal of this paper is to show the agricultural credit access landscape and investigate the impact of credit constraints on agricultural productivity in Ethiopia by using a household survey data from rural Amhara collected in 2013. After adjustments throughout the data cleaning process, the study relied on a survey of 1082 households which are found with valid information for all the variables considered in study. The study revealed that 66.17 percent of households are credit constrained which shows how the rural credit market landscape in Ethiopia is highly imperfect. By using an endogenous switching regression model, the study tried to show the effect of demographic and other socioeconomic variables on credit constraint status of households and simultaneously the impact of credit constraints on agricultural productivity. Finally, the paper uncovered the existence of a huge productivity loss due to various types of credit constraints. The cumulative impact is estimated to be 17.94 percent, i.e. an additional per hectare income of 1410.17 Ethiopian birr productivity gain if all types of credit constraints happen to be eliminated. This calls for a well-coordinated policy intervention compatible with the dynamics of rural institutions and other location bottlenecks.
