Does culture have a causal effect on economic development? The data on European regions suggest that it does. Culture is measured by indicators of individual values and beliefs, such as trust and respect for others, and confidence in individual selfdetermination. To isolate the exogenous variation in culture, I rely on two historical variables used as(More)

We develop and estimate a medium scale macroeconomic model that allows for unemployment and staggered nominal wage contracting. In contrast to most existing quantitative models, employment adjustment is on the extensive margain and the employment of existing workers is efficient. Wage rigidity, however, affects the hiring of new workers. The former is(More)
This paper uses a structural, large dimensional factor model to evaluate the role of ‘news’ shocks (shocks with a delayed effect on productivity) in generating the business cycle. We find that (i) existing small-scale VECM models are affected by ‘non-fundamentalness’ and therefore fail to recover the correct shock and impulse response functions; (ii) news(More)

We studied the effects of cardiac rehabilitation on the sympathovagal control of heart rate variability in 30 patients after a first, uncomplicated myocardial infarction. Twenty-two patients completed 8 weeks of endurance training (trained), while eight decided not to engage in the rehabilitation programme for logistical reasons, and were taken as untrained(More)
OBJECTIVES The aim of this multicenter randomized study was to investigate whether long-term physical training would influence left ventricular remodeling after anterior myocardial infarction. BACKGROUND Exercise is currently recommended for patients after myocardial infarction; however, the effects of long-term physical training on ventricular size and(More)
Congestive heart failure (CHF) is associated with an impaired flow-mediated vasodilation that reflects an impaired endothelial function. Limited information is available, however, on whether and to what extent this impairment is improved by pharmacological or nonpharmacological treatment. We measured radial artery diameter and blood flow by an echo-tracking(More)
AIMS Pulmonary arterial hypertension (PAH) reflects abnormal pulmonary vascular resistance and causes right ventricular (RV) hypertrophy. Enhancement of the late sodium current (INaL) may result from hypertrophic remodelling. The study tests whether: (i) constitutive INaL enhancement may occur as part of PAH-induced myocardial remodelling; (ii) ranolazine(More)
Long-QT syndrome (LQTS) is an arrhythmogenic disorder characterised by prolongation of the QT interval in the electrocardiogram, which can lead to sudden cardiac death. Pharmacological treatments are far from optimal for congenital forms of LQTS, while the acquired form, often triggered by drugs that (sometimes inadvertently) target the cardiac hERG(More)
