Ethiopia’s Investment Prospects: A Sectoral Overview*

Ethiopia is in the midst of a sustained growth surge that is becoming increasingly broadbased, building on major improvements in educational attainment, improved health outcomes, and infrastructure capacity in terms of access to power, transportation and telecommunications. The Government’s Growth and Transformation Plan sets ambitious targets for further improvements in these areas, together with significant reforms aiming to improve trade logistics, by rolling-out the authorized economic operator program across export-oriented industry parks and improving the main export corridor to Djibouti. This industrialization push coincides with global trends that provide Ethiopia an opportunity to integrate its economy into the modern “Made in the World” production system, including by attracting labor-intensive production, which is leaving China and other East Asian economies due to their rising wage rates. This paper considers Ethiopia’s prospects to succeed in this endeavor. It reviews overall economic management and performance indicators and provides a horizontal overview of the investment framework. It then summarizes the investment prospects in several major sectors of the economy, in light of Ethiopia’s emerging capacities and global developments: agriculture, mining, oil & gas, economic infrastructure, manufacturing, and selected services, including health and tourism. Keywords: Ethiopia, investment, growth and transformation pla

Estimation in a Competing Risks Proportional Hazards Model Under Length-biased Sampling With Censoring

International audienceWhat population does the sample represent? The answer to this question is of crucial importance when estimating a survivor function in duration studies. As is well-known, in a stationary population, survival data obtained from a cross-sectional sample taken from the population at time $t_0$ represents not the target density $f(t)$ but its length-biased version proportional to $tf(t)$, for $t>0$. The problem of estimating survivor function from such length-biased samples becomes more complex, and interesting, in presence of competing risks and censoring. This paper lays out a sampling scheme related to a mixed Poisson process and develops nonparametric estimators of the survivor function of the target population assuming that the two independent competing risks have proportional hazards. Two cases are considered: with and without independent consoring before length biased sampling. In each case, the weak convergence of the process generated by the proposed estimator is proved. A well-known study of the duration in power for political leaders is used to illustrate our results. Finally, a simulation study is carried out in order to assess the finite sample behaviour of our estimators

The F0F1-ATP Synthase Complex Contains Novel Subunits and Is Essential for Procyclic Trypanosoma brucei

The mitochondrial F0F1 ATP synthase is an essential multi-subunit protein complex in the vast majority of eukaryotes but little is known about its composition and role in Trypanosoma brucei, an early diverged eukaryotic pathogen. We purified the F0F1 ATP synthase by a combination of affinity purification, immunoprecipitation and blue-native gel electrophoresis and characterized its composition and function. We identified 22 proteins of which five are related to F1 subunits, three to F0 subunits, and 14 which have no obvious homology to proteins outside the kinetoplastids. RNAi silencing of expression of the F1 α subunit or either of the two novel proteins showed that they are each essential for the viability of procyclic (insect stage) cells and are important for the structural integrity of the F0F1-ATP synthase complex. We also observed a dramatic decrease in ATP production by oxidative phosphorylation after silencing expression of each of these proteins while substrate phosphorylation was not severely affected. Our procyclic T. brucei cells were sensitive to the ATP synthase inhibitor oligomycin even in the presence of glucose contrary to earlier reports. Hence, the two novel proteins appear essential for the structural organization of the functional complex and regulation of mitochondrial energy generation in these organisms is more complicated than previously thought

Is global democracy possible?

Scepticism about the possibility of a democratically governed global polity is often rooted in beliefs about ‘necessary conditions’. Some democracy scholars consider a transition to global democracy to be incompatible with necessary conditions for democratic governance, while some International Relations scholars consider it to be incompatible with necessary conditions for international structural change. This article assesses hypotheses and evidence about democratic transitions within states and transformations in the interaction among states and concludes that arguments based on necessary conditions are not compelling. This suggests that global democracy may be unlikely but it is not impossible

Penetrometer equipment and testing techniques for offshore design of foundations, anchors and pipelines

This paper attempts to categorise geotechnical field site characterisation tools in a hierarchical manner, as appropriate for the progression from initial surveys to detailed geotechnical design of specific infrastructure. In general, the hierarchy reflects more the sophistication, and hence cost, of the field tools, although small-scale tools developed to explore box core samples are something of an exception, with the potential for high quality data at low cost. These ideas are explored in the context of modern developments in equipment and methods of deployment, and in the manner in which the data may be used efficiently in design
