Impact of Fiscal Policy on Residential Investment in France.

The present paper assesses the impact of fiscal policy on residential investment in France. The analysis is conducted in the framework of a VECM, since this allows accounting for endogeneity between the variables. Our results imply that a long term relationship between investment and subsidies exists, making subsidies an adequate measure to influence residential investment and hence the business cycle. In addition, a disaggregated approach taking into account several different types of fiscal measures highlights that tax and interest rate subsidies are the most efficient fiscal tool for influencing residential investment. When accounting for financial factors by means of households' borrowing capacity, we find that the latter also impacts residential investment positively. Moreover, this alternative specification underlines the robustness of the above mentioned results, as it confirms subsidies as the most efficient measure to influence residential investment.Fiscal policy, residential investment, VECM.

The Impact of regulatory capital regulation on balance sheet structure, intermediation cost and growth

URL des Documents de travail : http://ces.univ-paris1.fr/cesdp/cesdp2016.htmlDocuments de travail du Centre d'Economie de la Sorbonne 2016.61 - ISSN : 1955-611XAs Europe is subject to a protracted recession, it should be asked whether the reform of the financial sector is not costly in terms of potential growth. Our analysis shows that the negative effect of the Basel III package excepted by the pre-QE studies are almost annihilated today. The recession must then have other causes: falling corporate lending volumes resulted from falling demand in the aftermath of the financial crisis, but this is longer the case. The EU is trying to incentivize corporate lending, via forward guidance as well as ‘supporting factor’ cutting down the Basel capital requirements. The macroeconomic theorists are trying to account for future success of monetary policy around zero nominal interest rate via the risk-taking channel. All these clever initiatives failed to deliver. As a consequence, we might infer that banks are simply not taking any risks: rather than appealing to risk aversion, we would like to argue that the banks seem especially embarrassed by future regulatory developments, which appear remote and uncertain. The binding constraint for corporate lending and growth in the EU is then plausibly a combination of banks' expectations of future regulation and strong uncertainty aversion. While we offer some mitigation prospects, we hope that the theoretical developments of the recent years will quickly yield both theoretical advances and practical results.Malgré les assouplissements récents de la règlementation bancaire afin de permettre une reprise des prêts aux entreprises, il semble que le paquet Bâle III ait un effet néfaste sur la croissance. Le texte s'interroge sur la contrainte active parmi l'ensemble des nouvelles règles. Il semblerait que les banques soient devenues très averses à l'incertitude, en particulier à l'incertitude sur l'évolution des règles qui leurs sont imposées. En conséquence nous proposons de modifier la nature des provisions en capital et le nombre de régulateurs ayant un pouvoir de décision sur le niveau des capitaux

Évolutions récentes de la productivité : accélération structurelle dans la zone euro et ralentissement structurel aux États-Unis ?

La croissance de la productivité dans la zone euro et aux États-Unis a connu sur la période récente des inflexions significatives, respectivement à la hausse et à la baisse, qui sembleraient relever en partie d’évolutions structurelles.Productivité, technologies de l’information et de la communication (TIC), dynamique sectorielle, évolutions structurelles.

Is prolonged infusion of piperacillin/tazobactam and meropenem in critically ill patients associated with improved pharmacokinetic/pharmacodynamic and patient outcomes? An observation from the Defining Antibiotic Levels in Intensive care unit patients (DALI) cohort

Objectives:We utilized the database of the Defining Antibiotic Levels in Intensive care unit patients (DALI) study to statistically compare the pharmacokinetic/pharmacodynamic and clinical outcomes between prolonged-infusion and intermittent-bolus dosing of piperacillin/tazobactam and meropenem in critically ill patients using inclusion criteria similar to those used in previous prospective studies.Methods: This was a post hoc analysis of a prospective, multicentre pharmacokinetic point-prevalence study (DALI), which recruited a large cohort of critically ill patients from 68 ICUs across 10 countries.Results: Of the 211 patients receiving piperacillin/tazobactam and meropenem in the DALI study, 182 met inclusion criteria. Overall, 89.0% (162/182) of patients achieved the most conservative target of 50% fT(> MIC) (time over which unbound or free drug concentration remains above the MIC). Decreasing creatinine clearance and the use of prolonged infusion significantly increased the PTA for most pharmacokinetic/pharmacodynamic targets. In the subgroup of patients who had respiratory infection, patients receiving beta-lactams via prolonged infusion demonstrated significantly better 30 day survival when compared with intermittent-bolus patients [86.2% (25/29) versus 56.7% (17/30); P=0.012]. Additionally, in patients with a SOFA score of >= 9, administration by prolonged infusion compared with intermittent-bolus dosing demonstrated significantly better clinical cure [73.3% (11/15) versus 35.0% (7/20); P=0.035] and survival rates [73.3% (11/15) versus 25.0% (5/20); P=0.025].Conclusions: Analysis of this large dataset has provided additional data on the niche benefits of administration of piperacillin/tazobactam and meropenem by prolonged infusion in critically ill patients, particularly for patients with respiratory infections

Lawson criterion for ignition exceeded in an inertial fusion experiment

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion
