Stabilization effects of social spending: Empirical evidence from a panel of OECD countries
2010
Abstract The aim of this paper is to assess the ability of social spending to smooth output shocks and to provide stabilization. The results show that overall social spending is able to smooth about 15 percent of a shock to GDP. Among its sub-categories, social spending devoted to Old Age, Health and Unemployment are those that contribute more to provide smoothing. Moreover, the stabilization effects of social spending are significantly larger in those countries where the size of social spending is higher, and in countries in which social spending is less volatile. The empirical results are economically and statistically significant, and robust.
Global imbalances and the intertemporal external budget constraint: A multicointegration approach
2013
Abstract This paper analyzes the external solvency of a group of 23 OECD countries for the period 1970–2012. The empirical strategy adopted underlines the increasing importance of the financial channel for the external adjustment as proposed in Gourinchas and Rey (2007) . We unify the traditional approaches to testing for external sustainability considering the stock-flow system created by the variables representing the external relationships of an open economy. External sustainability is tested using several types of cointegration and multicointegration tests. The results obtained point to weak sustainability in the flows analysis, whereas some degree of strong sustainability is found for …
New evidence on international R&D spillovers, human capital and productivity in the OECD
2002
Abstract In this article we show how the use of more reliable data on average years of schooling can change the conclusions about the magnitude of international R&D spillovers based on previous evidence, while pointing to a superior role of human capital.
Fiscal Convergence, Business Cycle Volatility and Growth
2009
This paper analyzes the effects of fiscal convergence on business cycle volatility and growth. Using a panel 21 OECD countries (including 11 EMU countries) and 40 years of data, we find that countries with similar government budget positions tend to have smoother business cycles. That is, fiscal convergence (in the form of persistently similar ratios of government surplus/deficit to GDP) is systematically associated with smoother business cycles. We also find evidence that reduced business cycle volatility through higher fiscal convergence stimulates growth. Our empirical results are economically and statistically significant and robust.
The effects of budget deficit on national saving in the OECD
2000
Abstract In this paper, we estimate a structural VAR using a panel of OECD countries, which includes national saving and budget deficit, both as the ratio to GDP, to test the Ricardian Equivalence hypothesis. In this framework, we separate saving and deficit movements into two types of shocks, associated with structural parameters of these economies. Our results suggest that Ricardian Equivalence did not work in our sample of OECD countries, since private saving compensated only a small fraction budget deficit. This supports the interpretation that the large budget deficits have been a very important factor behind the significant increase in real interest rates in the eighties and early nin…
Synthesis and evaluation of 2-tosylamino and 2-tosyliminopyrimidine derivatives as inhibitors of some leukocyte functions
2003
Abstract We have studied the potential anti-inflammatory effects of 20 2-tosylamino and 2-tosyliminopyrimidine new derivatives in human neutrophils. We have evaluated their interference with some leukocyte functions and 5-lipoxygenase activity. All the compounds reduced neutrophil degranulation process at concentrations in the μM range. Besides, compounds with a phenolic substitution inhibited leukotriene B 4 biosynthesis in neutrophils and decreased the cell-free 5-lipoxygenase activity. This study demonstrates that 2-tosylamino and 2-tosyliminopyrimidine derivatives can reduce the activation of neutrophil cells which may have relevance for the modulation of the inflammatory response.
Anti-Inflammatory Triterpenes from Pistacia terebinthus Galls
2002
From the galls of Pistacia terebinthus we obtained an extract that proved to be effective against chronic and acute inflammation. Now we report on the isolation and identification of three triterpenes: two tirucallane-type lanostanoids and one oleanane, which we have identified as masticadienonic acid (1), masticadienolic acid (2), and morolic acid (3), respectively. All of them showed effectiveness on the mouse ear inflammation induced by repeated applications of 12-O-tetradecanoylphorbol 13-acetate and on the phospholipase A2-induced foot paw edema. The pharmacological activity of the compounds was ratified by a histological study of the ear samples. In addition, they inhibited leukotrien…
MHD simulations of the in situ generation of kink and sausage waves in the solar corona by collision of dense plasma clumps
2019
Funding: This research has received funding from the UK Science and Technology Facilities Council (Consolidated Grant ST/K000950/1) and the European Union Horizon 2020 research and innovation programme (grant agreement No. 647214). P.A. acknowledges funding from his STFC Ernest Rutherford Fellowship (No. ST/R004285/1). This research was supported by the Research Council of Norway through its Centres of Excellence scheme, project number 262622. Context. Magnetohydrodynamic (MHD) waves are ubiquitous in the solar corona where the highly structured magnetic fields provide efficient wave guides for their propagation. While MHD waves have been observed originating from lower layers of the solar …
The impact of the Eurofever criteria and the new Infevers MEFV classification in real life: results from a large international FMF cohort
2022
INTRODUCTION: New Eurofever/PRINTO classification criteria (EPCC) for Familial Mediterranean Fever (FMF) and other recurrent fevers have been recently developed, together with the classification of the pathogenicity of MEFV variants. OBJECTIVES: To evaluate the impact in real life of both the EPCC and INSAID pathogenicity classification of MEFV variants in the large international Eurofever FMF cohort. METHODS: Baseline demographic, genetic and clinical data of FMF patients included in the Eurofever registry were evaluated. The EPCC and the 2018 INSAID classification for MEFV variants were applied in all eligible FMF patients. RESULTS: Since November 2009, clinical information was available …
Depression comorbid with tuberculosis and its impact on health status: cross-sectional analysis of community-based data from 48 low- and middle-incom…
2017
Background Depression in tuberculosis increases the risk for adverse health outcomes. However, little is known about comorbid depression and tuberculosis in the general population. Thus, we assessed the association between depression and tuberculosis, and the decrements in health status associated with this comorbidity in 48 low- and middle-income countries. Methods Cross-sectional, community-based data from the World Health Survey on 242,952 individuals aged ≥ 18 years were analyzed. Based on the World Mental Health Survey version of the Composite International Diagnostic Interview, past 12-month depression was categorized into depressive episode, brief depressive episode, subsyndromal dep…
