This paper examines the impact of labor and capital income taxes in a stochastic overlapping generations (OLG) economy where agents face borrowing constraints and their behavior is temptation driven. We quantitatively establish that the existence of temptation in preferences may function as an opposing mechanism to modeling choices, such as liquidity constraints, life-cycle structure, and idiosyncratic earnings risks, that are critical in delivering a positive capital income tax rate. We show that a sufficiently large measure of individuals having self-control preferences, or alternatively, a sufficiently high cost of exercising self-control, puts downward pressure on the optimal capital income tax rate. (JEL E21, E62, H55), I. INTRODUCTION A central research question in the dynamic fiscal policy literature during the last 30 years or so, is whether under fairly general modeling choices, the government should impose [...]

Thanopoulos (a) Abstract: We analyze the welfare effects of an unfunded social security system. We do so using an overlapping generations economy wherein agents have self-control preferences, face mortality risk, individual income risk, and borrowing constraints. Given our specification of preferences, unfunded social security helps reduce the agents' temptation to consume in every period; consequently, the welfare costs it otherwise entails are substantially mitigated. While both social security and self-control when considered separately reduce welfare, their combination renders this effect considerably less severe. Moreover, if the cost of resisting temptation is very high, the introduction of social security might even improve welfare.

Abstract. Perimembranous ventricular septal effects (PMVSDs) are the most common congenital cardiac defects of clinical importance. During the last decade, transcatheter closure of PMVSDs has been attempted using various occluders [...]

True muscular ventricular septal defects (MVSDs) account for approximately 10-15% of congenital VSDs and can be single or multiple, existing anywhere in the septum [1] The most common form of [...]

Thanopoulos (2) Keywords: Key words: Myocarditis -- Troponins -- Adenovirus -- Immunoglobulin Abstract: We report a successful outcome on an acute adenovirus myocarditis treated with a 24-hour high-dose intravenous immunoglobulin (24-HDIVIG) in a 4.5-year-old girl. A postviral etiology of acute myocarditis was assessed on the basis of the polymerase chain reaction technique. Among other early markers of cardiac injury, cardiac isoform of troponin-I (cTnI) was significantly correlated to the left ventricular ejection fraction (r=-0.86, p &lt 0.0001). Follow-up of cTnI, which might also be correlated to the short-term outcome, allows fast, easy, and noninvasive estimation of response to the aggressive treatment with 24-HDIVIG in acute adenovirus myocarditis in children.

Thanopoulos (1) Keywords: Key words: Anomalous pulmonary artery -- Right ventricular contractility -- Infant Abstract: Anomalous origin of the right pulmonary artery from the ascending aorta (AORPA) with severe right ventricular dysfunction in a neonate was completely diagnosed by echocardiography. Cardiac catheterization was performed to explore further right ventricular dysfunction, which is extremely rare at this age. Following cardiac catheterization, the patient died. We suggest that in critically ill infants with the aforementioned condition surgical repair guided by modern echocardiography must be the chosen management.

The aim of the study was to report initial human experience with transcatheter closure of PDA in 25 patients using the new Amplatzer duct occluder (ADO II) (AGA Medical, Golden Valley, MN).
