    This paper decomposes the sources of the peace dividend into global, regional, and country-specific factors, and analyzes their relative importance. It finds that the easing of international and regional tensions and the existence of IMF-supported adjustment programs are systematically related to lower military spending and a higher share of nonmilitary spending in total government outlays. The easing of international tensions and of regional tensions since the end of the Cold War and the existence of IMF-supported adjustment programs account for 66 percent, 26 percent, and 11 percent of the decline in military spending, respectively. Furthermore, fiscal adjustment has implied a larger cut in military spending of countries with IMF-supported programs. Copyright 2001, International Monetary Fund

    Postconflict Countries: Strategy for Rebuilding Fiscal Institutions

    Get PDF
    This paper reviews the challenges and experiences in rebuilding fiscal institutions in postconflict environments, based on advice from the IMF's Fiscal Affairs Department to selected countries. The recommended strategy involved a three-step process of (i) creating a proper legal framework for fiscal management, (ii) establishing a central fiscal authority and a mechanism for co-ordinating foreign assistance, and (iii) designing appropriate tax policies while simultaneously creating simple tax administration and expenditure management arrangements. The advice was tailored to the circumstances of postconflict countries, and in some cases involved transitional measures that were not first best from an efficiency standpoint. In a similar vein, recommendations on revenue administration and expenditure management focused on the most basic tasks and procedures. In providing advice, care was taken to ensure that these measures were consistent with the eventual transformation to a modern fiscal management system.fiscal policy, tax, institutions, conflict

    This paper reviews the key challenges in rebuilding fiscal institutions in post-conflict countries. Based on IMF technical assistance advice, it proposes a three-step framework for the creation or re-establishment of well-functioning public finance institutions: (i) creating a proper legal framework for fiscal management, (ii) establishing a central fiscal authority, and (iii) designing appropriate tax policies while simultaneously creating simple tax administration and expenditure management arrangements.post-conflict, fiscal instutions, public expenditure management, tax administration

    Climate change and government borrowing costs : a triple whammy for emerging market economies

    Climate change is a systemic risk to the global economy. While there is a large body of literature documenting the potential economic consequences of climate change, there is relatively little research on the link between vulnerabilities to climate change, the buildup of climate debt by countries with historically large carbon dioxide emissions, and how well financial markets incorporate (or not) these risks to sovereign governments. This paper investigates the impact of both climate debt and climate vulnerabiities/resiliency on sovereign bond yields and spreads in advanced and emerging market economies, using a novel dataset. We find that changes in climate debt are an important determinant of spreads, but only in emerging market economies. Countries with high vulnerabilities and low resilency to climate change also pay higher spreads. This implies a triple whammy of challenges for emerging market economies as they confront the economic damages of climate change, the high fiscal costs of climate adaptation, and high borrowing costs.info:eu-repo/semantics/publishedVersio

    Terror and its fiscal consequences

    Get PDF
    We explore the impact of major terrorism shocks on macroeconomic and fiscal variables´ dynamics using an unbalanced panel of 191 heterogeneous countries from 1970 to 2018. By means of the local projection method, we find that a terrorist shock lowers a country’s real GDP as well as government tax revenues and raises debt-to-GDP ratio. The composition of government spending shifts in favor of military spending. Low-income countries are affected more than both emerging market and advanced economies. Our results are robust to a battery of sensitivity and robustness tests.info:eu-repo/semantics/publishedVersio

    Laboratory selection for an accelerated mosquito sexual development rate

    <p>Abstract</p> <p>Background</p> <p>Separating males and females at the early adult stage did not ensure the virginity of females of <it>Anopheles arabiensis </it>(Dongola laboratory strain), whereas two years earlier this method had been successful. In most mosquito species, newly emerged males and females are not able to mate successfully. For anopheline species, a period of 24 h post-emergence is generally required for the completion of sexual maturation, which in males includes a 180° rotation of the genitalia. In this study, the possibility of an unusually shortened sexual maturity period in the laboratory-reared colony was investigated.</p> <p>Methods</p> <p>The effect of two different sex-separation methods on the virginity of females was tested: females separated as pupae or less than 16 h post-emergence were mated with males subjected to various doses of radiation. T-tests were performed to compare the two sex-separation methods. The rate of genitalia rotation was compared for laboratory-reared and wild males collected as pupae in Dongola, Sudan, and analysed by Z-tests. Spermatheca dissections were performed on females mated with laboratory-reared males to determine their insemination status.</p> <p>Results</p> <p>When the sex-separation was performed when adults were less than 16 h post-emergence, expected sterility was never reached for females mated with radio-sterilized males. Expected sterility was accomplished only when sexes were separated at the pupal stage. Observation of genitalia rotation showed that some males from the laboratory strain Dongola were able to successfully mate only 11 h after emergence and 42% of the males had already completed rotation. A small proportion of the same age females were inseminated. Wild males showed a much slower genitalia rotation rate. At 17 h post-emergence, 96% of the laboratory-reared males had completed genitalia rotation whereas none of the wild males had.</p> <p>Conclusion</p> <p>This colony has been cultured in the laboratory for over one hundred generations, and now has accelerated sexual maturation when compared with the wild strain. This outcome demonstrates the kinds of selection that can be expected during insect colonization and maintenance, particularly when generations are non-overlapping and similar-age males must compete for mates.</p

    The emerging role of Nrf2 in mitochondrial function

    The transcription factor NF-E2 p45-related factor 2 (Nrf2; gene name NFE2L2) allows adaptation and survival under conditions of stress by regulating the gene expression of diverse networks of cytoprotective proteins, including antioxidant, anti-inflammatory, and detoxification enzymes as well as proteins that assist in the repair or removal of damaged macromolecules. Nrf2 has a crucial role in the maintenance of cellular redox homeostasis by regulating the biosynthesis, utilization, and regeneration of glutathione, thioredoxin, and NADPH and by controlling the production of reactive oxygen species by mitochondria and NADPH oxidase. Under homeostatic conditions, Nrf2 affects the mitochondrial membrane potential, fatty acid oxidation, availability of substrates (NADH and FADH2/succinate) for respiration, and ATP synthesis. Under conditions of stress or growth factor stimulation, activation of Nrf2 counteracts the increased reactive oxygen species production in mitochondria via transcriptional upregulation of uncoupling protein 3 and influences mitochondrial biogenesis by maintaining the levels of nuclear respiratory factor 1 and peroxisome proliferator-activated receptor Îł coactivator 1Îą, as well as by promoting purine nucleotide biosynthesis. Pharmacological Nrf2 activators, such as the naturally occurring isothiocyanate sulforaphane, inhibit oxidant-mediated opening of the mitochondrial permeability transition pore and mitochondrial swelling. Curiously, a synthetic 1,4-diphenyl-1,2,3-triazole compound, originally designed as an Nrf2 activator, was found to promote mitophagy, thereby contributing to the overall mitochondrial homeostasis. Thus, Nrf2 is a prominent player in supporting the structural and functional integrity of the mitochondria, and this role is particularly crucial under conditions of stress

    Standalone vertex nding in the ATLAS muon spectrometer

    A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spectrometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to bbar b final states, and pp collision data at √s = 7 TeV collected with the ATLAS detector at the LHC during 2011
