    Parallel Title: Al-Batuly, Abdulmajeed Achieving the MDGs in Yemen
    Abstract: Once the current political crisis in Yemen has been resolved, it will be ever more urgent to speed up progress, including Millennium Development Goal (MDG) achievements. Drawing on simulations with the Maquette for MDG Simulations (MAMS), a model for strategy analysis, and a linked microsimulation model, this paper addresses Yemen's MDG challenges. A first simulation set considers scaled-up government actions with the aim of fully achieving the 2015 international MDG targets with required additional financing from foreign or domestic sources. The main finding is sobering but not surprising: given the required expansion of MDG-related services, on-time achievement of key MDG targets does not appear to have been a realistic objective even if the government, hypothetically, would have expanded services with grant aid financing starting from 2005; macroeconomic stability, government efficiency, and the production of tradables would all have suffered due to the size of spending and aid increases as well as the resulting real exchange rate appreciation. The results suggest that countries, instead of relying on international targets, should set MDG targets grounded in their own reality. In light of these results, the authors designed a second simulation set that is focused on the remaining period up to 2015, and on what may be feasible once the current conflict has been settled. The simulations introduce moderate increases in foreign aid or government allocative efficiency. The government uses the resulting fiscal space for spending and service expansion in infrastructure and human development without losses in productive efficiency. The results suggest that, under these conditions, substantial improvements could still be achieved

    Parallel Title: Erscheint auch als Lofgren, Hans A Proximity-Based Approach to Labor Mobility in CGE Models with an Application to Sub-Saharan Africa
    Abstract: The ease with which workers can move between sectors has a strong impact on the effects on labor markets of shocks such as changes in world prices or migration flows. This paper introduces an approach to labor mobility with frictions under which worker capabilities (their efficiencies in different sectors) depend on their sector affiliation. If workers in sector a move to sector a', their efficiency shortfall due to a capability misfit compared to what is needed in a' (and possessed by workers already in a') is measured by a proximity parameter, 0 ? proxa,a' ? 1. If proxa, a' 〈 1, the efficient quantity reaching a' is below the physical quantity. In this setting, profit-maximizing producers are willing to pay the same wage per efficiency unit irrespective of worker origin and thus pay less efficient workers a lower wage per physical unit. This approach to labor mobility is tested in a static CGE model that is applied to an illustrative sub-Saharan African dataset with sector proximities defined using the approach of the product-space literature. Simulations of positive export price shocks show that, the higher the proximities, the stronger the labor reallocation and the welfare gains

    Abstract: Over nine years of violence and conflict have profoundly altered the Republic of Yemen's economy. The war has shattered the country's already fragile socioeconomic equilibria, affecting nearly every facet of life. Since the onset of the conflict, economic diagnostics have focused on descriptions of the deteriorating macro-fiscal and poverty conditions, lack of food security, and loss of capital accumulation. However, relatively little attention has gone toward the development of a forward-looking vision for the country, rooted in Yemen's current economic structure. This paper helps to fill this gap by presenting and analyzing a set of scenarios for Yemen's economy up to 2030. The analysis is based on a new version of the Sustainable Development Goal Simulation model, a dynamic computable general equilibrium (CGE) model, which is applied to a new social accounting matrix (SAM) for Yemen. The new social accounting matrix has the virtue of consolidating sparce and often inconsistent Yemeni data from multiple sources (the World Bank, the International Monetary Fund, and the United Nations system) into a coherent framework that reflects the basic structure of the economy, both at the macro and sectoral levels. The simulation analysis is built around three broad scenarios spanning 2022 through 2030. The results suggest that if the conflict subsides, governance is strengthened, and the donor community provides crucial aid, considerable progress, including reduced poverty rates and improved living conditions, can be achieved by 2030. Given Yemen's low levels of infrastructure and human development, the potential payoffs from investments in these areas are great
