The African Capacity for Immediate Response to Crisis: conceptual breakthrough or anti-imperialist phantom?

The creation of an African Capacity for Immediate Response to Crisis (ACIRC) is a sign of Africa's willingness to take its destiny into its own hands. Presented as a reaction to the slowness of the development of the African Standby Force (ASF), it is also a response to some of the ASF's conceptual weaknesses. This decision reflects a wish to establish an instrument better equipped to deal with the challenges Africa is facing. Departing from the (sub)regional logic of the ASF results from a desire to take into account the transnational nature of threats, while its enlarged mandate is meant to offer Africa the capacity to intervene in all kinds of conflicts, including by undertaking peace enforcement activities. But the obstacles on the road towards the actual creation and mobilisation of this capacity should not be underestimated. These include material difficulties, but also political tensions, between ‘small’ and ‘big’ states as well as between the African Union and subregional organisations. The risk then is high that the ACIRC, whose announcement came as a reaction to France's intervention in Mali, ends up joining the ranks of the many ‘anti-imperialist’ phantoms haunting the history of the Organization of African Unity/African Union (OAU/AU). Confronted by events considered ‘neocolonial’ initiatives, African actors have indeed traditionally reacted by launching grand projects that never got off the ground. However, by actually establishing this new instrument, they may also demonstrate that times have definitively changed.     

The African Peace and Security Architecture and its partners

This article presents survey data on the African Peace and Security Architecture (APSA). It focuses explicitly on two aspects: the internal constitution and achievements of the APSA; and coordination and cooperation with external actors, such as Regional Economic Communities, the United Nations and the European Union. The survey, conducted between October 2011 and December 2012, targeted 198 security experts in international organisations, think tanks, academia and non-governmental organisations. It reveals the APSA's current stage of development, achievements and challenges.

Does Military Spending Really Matter for Economic Growth in China and G7 Countries: The Roles of Dependency and Heterogeneity

This study revisits the causal linkages between military spending and economic growth in China and G7 countries (i.e. Canada, France, Germany, Italy, Japan, the UK, and the USA) by focusing country-specific analysis for the period 1988–2010. The panel causality analysis, which accounts for both cross-country dependency and heterogeneity across countries, is employed in this study. Our results find evidence of the neutrality hypothesis for Italy, France, and Germany, the military spending–growth detriment hypothesis for both Canada and the UK, and one-way Granger causality running from economic growth to military spending for China. Furthermore, we find a feedback between military spending and economic growth in both Japan and the USA. Thus, our results do not support that one size fits all.

AFRICA'S TRIPLE TRANSITION

Sub-Saharan Africa has witnessed the end of foreign colonial rule, the rise and fall of autocratic political regimes, and the disappearance of statist command economies. The challenges were to turn populations into coherent nations owing allegiance to the state; to democratise the state structures that govern these populations; and to liberalise the rules that regulate economic transactions. An important source to assess these prospects are the views and attitudes of ordinary Africans. This essay reflects on the original data derived from a crossnational research project. Nine African states were surveyed between 1999 and 2000. An attempt is made to gather some propositions from the analysis of the data. Many present serious challenges to common wisdom about African politics. It appears that the process of nationbuilding has created coherent political communities with high levels of national identity; that democratising the state in Africa builds on existing indigenous demands from ordinary Africans; and that economic liberalisation proceeds in the face of a mixed set of values about market and state.     

A rent‐seeking model of international competition and alliances∗

This paper presents an alternative approach for analyzing international competition and alliances as rent‐seeking contests that are able to capture the impure public good nature of defense spending. Two‐country Cournot and Stackelberg games are considered and comparative static results derived. A three‐country model is investigated, and alliance behavior is explored in the context of this rent‐seeking model. The conjecture that an alliance may become less effective if the allies’ interests become more closely aligned is verified. Finally, the model is generalized, and a Nash‐Cournot equilibrium is computed.     

How should modeling and simulation be used to support defense acquisition?

This paper investigates the potential for modeling and simulation to contribute to new defense system development, by increasing the productivity of traditional R&D in developing system‐specific technology. Building on a previous optimal control model of defense system R&D, it shows that (1) the optimal use of modeling is related in a natural way to that of traditional R&D, and (2) both have similar optimal profiles over time. Simulated results based on limited historical data suggest that optimal use of modeling could increase the rate of growth in system‐specific technology significantly.     

ON THE CHOICE OF MULTI-TASK R&D DEFENSE PROJECTS: A CASE STUDY OF The ISRAELI MISSILE DEFENSE SYSTEM

Investments in R&D constitute a major share of the expenditures of the hi-tech industry since, generally, they enable firms to successfully compete in the rapidly and constantly changing markets for hi-tech products and services. The role of R&D projects is particularly important in the areas of defense and homeland security due to the nature of warfare and the continuous threats posed by arms races and by terror organizations. This study analyzes the choice of the R&D projects designed to counter multiple related military threats. It develops the methodology required to assess whether it is preferable to develop one project to thwart several related threats, or several distinct projects, each of which provides an answer to one specific threat or a partial set of the threats. An analytic solution is provided and assessed for two simple models with two related threats. A solution of the model is then provided for any number of related threats, using a dynamic programming methodology. Finally, we demonstrate the usefulness of our model and methodology to Israel’s missile defense problem; that is, we show how to optimally develop systems aimed at thwarting the multiple threats of short-, medium-, and long-range missiles.     

Resourcing for defense: Solving the roles and missions puzzle

One of the most important issues facing the post‐Cold War U.S. defense establishment concerns the future allocation of combat tasks and responsibilities among different branches of the armed forces. The challenge is to reduce unnecessary redundancy across roles and missions when resources are highly constrained, without compromising military effectiveness. Defining the policy problem as one of resource allocation rather than operational effectiveness, we develop a methodology for allocating roles and missions. Our methodology focuses at the highest level of force aggregation and uses a mathematical programming model to produce cross‐service cross‐mission trade‐offs that will yield the best total force combat and non‐combat potential within resource consumption constraints.
