Agricultural trade liberalization under Doha: the risks facing African countries
African countries tend to be affected by global agricultural policies in the same way as other economies but with much more severe economy-wide repercussions... The present discussion paper 1) examines the vulnerability of Africa economies with respect to global agricultural trading policies and their induced changes in world agricultural markets, based on the above characteristics; 2) analyzes the efficiency effects within Africa's agricultural sector of world market distortions resulting from agricultural trading policies; 3) illustrates the impact of global protectionism on poverty levels and distribution among rural households in Africa and the implication for the objective of poverty reduction; 4) reviews the options and risks facing African countries in their pursuit of opportunities for greater participation in the global trading system, in particular in connection with the Doha trade agenda; and 5) discusses options for global trade liberalization that would best benefit African economies. The paper argues that the insistence on the part of African countries on Special and Differential Treatment entails much more risks than benefits for their economies. It also indicates that trade preferences have been less beneficial to African economies than usually assumed and at any rate have not been significant enough to compensate African countries for the negative impact of global protectionism. Finally, the paper also disagrees with the widely accepted conclusion that African countries would suffer from liberalization of global agricultural policies because they tend to be net food importers. That conclusion does not sufficiently take into consideration the dynamic long term effects of global policy changes on production and trading patterns among African countries and the potential efficiency effects that would emanate there from.Agricultural policies, International trade, agricultural sector, Protectionism, Doha agreement, trade liberalization, Poverty reduction, Rural households,
Sustaining and accelerating Africa's agricultural growth recovery in the context of changing global food prices:
"Starting in the mid-1990s, Africa embarked upon its longest period of sustained, positive per capita income growth since the 1960s. This growth recovery has made a dent in poverty and holds out hope that a number of African countries may reach the Millennium Development Goal targets for poverty and food security (MDG 1), if not by 2015, then within the following few years. Agricultural growth has been, and will remain, key to reducing poverty and hunger in Africa. To significantly reduce poverty, Africa needs to sustain, broaden, and accelerate its recent growth performance and boost its investments in agriculture. The recent spike in global food prices represents an opportunity that could support further agricultural sector growth in Africa. The unfolding financial crisis, on the other hand, could have the reverse effect, especially if it leads to lower investments in the sector." from author's abstractFood prices, Agricultural growth, economic recovery, Development assistance,
The growth-poverty convergence agenda: Optimizing social expenditures to maximize their impact on agricultural labor productivity, growth, and poverty reduction in Africa
The need to achieve the Millennium Development Goals (MDGs) has raised the profile of social sector investments in Africa and other developing countries. As a result, many African countries are pressured to emphasize short-term concerns related to the symptoms of poverty at the expense of the longer-term needs to raise productivity and incomes, and thereby tackle the real roots of poverty. Because of scarce budget resources, there is a major challenge for African governments in terms of ensuring the necessary consistency of policies and strategies to promote long-term economic growth, raise smallholder productivity, achieve food security, and reduce poverty, while providing the social services that respond to immediate welfare requirements. The main objective of the convergence agenda exposed in this paper is to identify strategies that would allow developing countries to improve the management of public expenditures so as to raise the chances of meeting the income growth and social needs of their populations under tight budget constraints. In this paper we have (1) discussed the terminology used in describing the problem being studied and formulated the assumptions and hypotheses underlying the research; (2) defined a typology of growth–poverty pathways; (3) developed metrics to measure the strength of the relationship between growth and poverty reduction; (4) laid out the theory for the measurement of the degree of convergence of public expenditures on social services, that is, the extent to which they are optimized with respect to their impact on labor productivity and growth; and (5) outlined models for (a) the quantification of social services availability at the local level using a single-score concept, (b) the evaluation of the quality and efficiency of public expenditures in social services sectors in rural areas, and (c) the optimization of public expenditures allocation to maximize the impact on growth and poverty reduction; as well as (6) provided initial evidence proving the validity of the theory of convergence.Poverty, Expenditure, Social services, Convergence, Agriculture, Poverty overhang, Growth deficit, Public investment,
Non-equilibrium Josephson effect through helical edge states
We study Josephson junctions between superconductors connected through the
helical edge states of a two-dimensional topological insulator in the presence
of a magnetic barrier. As the equilibrium Andreev bound states of the junction
are 4Pi-periodic in the superconducting phase difference, it was speculated
that, at finite dc bias voltage, the junction exhibits a fractional Josephson
effect with half the Josephson frequency. Using the scattering matrix
formalism, we show that signatures of this effect can be seen in the
finite-frequency current noise. Furthermore, we discuss other manifestations of
the Majorana bound states forming at the edges of the superconductors.Comment: 4+ pages, 3 figure
Emerging policies and partnerships under CAADP: Implications for long-term growth, food security, and poverty reduction
The Comprehensive Africa Agriculture Development Programme (CAADP) is one of the main components of the New Partnership for Africa's Development (NEPAD). CAADP is an initiative launched by the African Union Commission (AUC) in 2002 to serve as a continent-wide framework to facilitate faster agricultural growth and progress toward poverty reduction and food and nutrition security in Africa. CAADP seeks to promote policies and partnerships and raise investments in Africa's agricultural sector and achieve better development outcomes. It is an unprecedented, comprehensive effort to rally governments and other stakeholders around a set of key values and principles; create partnership mechanisms at continental, regional, and country levels; promote evidence-based and outcome-driven policy design and implementation; and establish inclusive dialogue and review processes to increase the effectiveness of the development process among African countries. This paper examines the new policy and investment planning and the review, dialogue, and partnership modalities and evaluates their likely impact on future growth and poverty-reduction outcomes.Agriculture, CAADP, Growth, NEPAD, Nutrition, partnership, Poverty,
Spatial price transmission and market integration in Senegal’s groundnut market
The groundnut sector is the largest of Senegal’s agricultural sectors. It has been subject to various degrees of intervention since the country’s independence. Some, including the determination of farm prices by the government have survived the wave of reforms of the 1980s. Groundnut pricing policies have been the source of major transfers from farmers to the groundnut milling industry, which until 2007, was dominated by SONACOS, a publicly owned parastatal. The state was thus a major beneficiary of the transfers. In 2007, the company was privatized and is now privately owned, raising even greater concerns about the distribution of implications of pricing policies for groundnuts. The paper examines the potential ramifications of liberalizing groundnut prices in terms of its impact on prices received by producers and paid by the milling industry. One fundamental question in the analysis is the extent to which local markets would respond to such a move. To answer this question, the paper presents a dynamic model of price formation that uses estimates of spatial integration across local markets to measure the response of local agricultural prices to policy changes. We then apply this model to simulate the impact of liberalizing groundnut prices to allow domestic prices to reflect their international levels. We find that doing so would change prices in the border city of Dakar, which happens to be the central market that determines prices in the local markets of the producing regions of Kaolack and Fatick. We also find that if markets had been fully liberalized when SONACOS was privatized in January 2007, then groundnut prices would have been higher and that the increase in prices would have been passed on almost entirely to producers in Kaolack and, to a lesser extent, to producers in Fatick. Such reforms would have reversed the longstanding discrimination of groundnut farmers. Prices received by farmers in Kaolack over a period of one year would have increased from 352 FCFA/kg to 494 FCFA/kg of shelled groundnuts. For farmers in the Fatick region, prices would increase from 389 FCFA/kg to 474 FCFA/kg.groundnuts, Liberalization, marketing integration, pricing policies, Privatization,
Ac Josephson Effect in Topological Josephson Junctions
Topological superconductors admit zero-energy Majorana bound states at their
boundaries. In this review article, we discuss how to probe these Majorana
bound states in Josephson junctions between two topological superconductors. In
the absence of an applied bias, the presence of these states gives rise to an
Andreev bound state whose energy varies -periodically in the
superconducting phase difference. An applied voltage bias leads to a
dynamically varying phase according to the Josephson relation. Furthermore, it
leads to dynamics of the occupation of the bound state via its non-adiabatic
coupling to the continuum. While the Josephson relation suggests a fractional
Josephson effect due to the -periodicity of the bound state, its
observability relies on the conservation of the occupation of the bound state
on the experimentally probed time scale. We study the lifetime of the bound
state and identify the time scales it has to be compared to. In particular, we
are interested in signatures of the fractional Josephson effect in the Shapiro
steps and in current noise measurements. We also discuss manifestations of the
zero-energy Majorana states on the dissipative subgap current.Comment: 19 pages, 12 figure
Beyond Myth and Ceremony?: An Examination of Corporate Responses to Climate Change.
The focus of this dissertation is on corporate responses to climate change. Using three empirical studies, I examine the gap in corporate words and actions when it comes to addressing climate change through three empirical studies. The first study uses critical theory to analyze how firms decouple climate change discourse and actions through an examination of Environmental Protection Agency Climate Leaders participants. The second study uses textual analysis of sustainability reports to examine the underlying logics of corporations addressing climate change. Finally, I present an ethnographic and historical case study of Ford Motor Company and their journey from symbolic to substantive climate change response to better understand the mechanisms and tensions underlying such change. Throughout the three chapters, the themes of opportunity and belief in the science of climate change stand out as important motivating factors driving substantive corporate response to the issue.PHDNatural Resources and EnvironmentUniversity of Michigan, Horace H.

Building capacities for evidence and outcome-based food policy planning and implementation
The Comprehensive Africa Agriculture Development Programme (CAADP) is an Africawide framework for revitalizing agriculture and rural development in order to accelerate economic growth and progress toward poverty reduction and food and nutrition security. This study reviews CAADP and its strategic objectives, key players, implementation modalities, and approach to ensuring evidence and outcome-based policy planning and implementation. The study also lays out CAADP’s common analytical framework at the country level and shares economic modeling results from member countries of the Economic Community of West African States (ECOWAS) in which analysis was conducted to examine agricultural growth and investment options for meeting CAADP growth and expenditure targets and the Millennium Development Goal target of halving poverty. Finally, the paper discusses CAADP’s review and dialogue mechanisms and knowledge support systems that have been put in place to facilitate benchmarking, mutual learning, and capacity strengthening that will improve agricultural policy, program design, and implementation.CAADP, ECOWAS, growth options, MDG 1, Poverty reduction, public expenditure,
