Integrating Retirement and Long-Term Care (LTC) Annuities Using a Notional Defined Contribution (NDC) Framework
2014
This paper examines the possibility of embedding public long-term care (LTC) insurance within the retirement pension system, i.e. introducing life care annuities (LCAs) into a notional defined contribution (NDC) framework. To do this we develop a multistate overlapping generations model (MOLG) that includes the so-called survivor dividend and give special attention to the assumptions made about mortality rates for dependent persons and LTC incidence rates, which largely determine the contribution rate assigned to LTC. The proposed model could be of interest to policymakers because it could be implemented without too much difficulty, it would universalize LTC coverage with a "fixed" cost, an…
An Integrated Notional Defined Contribution (NDC) Model with Retirement and Permanent Disability
2014
In this paper we develop a theoretical basis for integrating retirement and permanent disability using a generic NDC framework. The methodology used relies on a multistate overlapping generations model that includes the so-called survivor dividend. Currently this feature can only be found in the Swedish defined contribution (DC) scheme. The results achieved in the numerical example we present endorse the fact that the model works well. Special attention is given to the assumptions made about mortality rates for disabled people and disability incidence rates, which largely determine the contribution rate assigned to disability. The model could be of interest to policymakers because, after so…
Feasibility analysis and study of a grid-connected hybrid electric system: Application in the building sector
2016
This paper represents the feasibility study and analysis of a grid-connected hybrid (PV-Wind) system with battery, realized within the project DE.DU.ENER.T and installed in the research centre CRTEn located in the northern Tunisia in the city of Borj-Cedria. The main objective of this work is to exploit renewable sources of electrical energy production to electrify the desired building. So, to minimize electricity consumption costs, reduce the adverse effects of pollutants products from the diesel power systems and sometimes happen to sell the surplus of energy produced. The HOMER (Hybrid Optimization Model of Electric Renewable) software is used to estimate system size and its performance …
Influence of doped charge transport layers on efficient perovskite solar cells
2018
Planar vacuum deposited p–i–n methyl ammonium lead tri-iodide perovskite solar cells are prepared with different electron and hole transporting layers, either doped or undoped. The effect of these layers on the solar cells performance (efficiency and stability) is studied. The main benefit of using doped layers lies in the formation of barrier free charge extraction contacts to the electrodes. However, this comes at the cost of increased residual absorption (reducing the current density and efficiency of the cells) and a decreased stability. A generic solar cell structure using undoped charge extraction layers is presented, containing a thin layer of a strong electron acceptor in between th…

Notes on Using the Hidden Asset or the Contribution Asset to Compile the Actuarial Balance for Pay-as-You-Go Pension Systems
2010
The aim of this paper is twofold: to determine the connection between the “contribution asset” and the “hidden asset” and to discover whether using either of them to compile the actuarial balance in Swedish-type pay-as-you-go pension systems will provide a reliable solvency indicator. We develop an overlapping generations model and apply it to the defined benefit pay-as-you-go system, although it would be just as valid for NDC systems. On the theoretical side the main conclusion is that, despite their very different natures, in a simplified scenario the contribution asset and the hidden asset could coincide if r - the real rate of interest - is equal to the growth in the wage bill. On the a…
L’ESPERIENZA DEL PNRR: LE FONTI DEL DIRITTO DAL POLICENTRISMO ALLA NORMAZIONE EURO-GOVERNATIVA
2022
The A. gives an overview of the Euro-National normative framework under which the National Plan of Recovery and Resilience of the Italian State (NPRR) hase been developed and it is implemented. The core of the analysis is the impact of EU norms regulating Next generation EU and the Recovery and Resilience Facility on the Italian Constitutional "order" of sources of Law. It is dedicated particular attention to the "legislative measures" defined in the NPRR, the system of evaluation of compliance to the Plan concerning those measures and the normative "practice" of its implementation. The main target of the research is to evaluate if both the pandemic emergency and the legal responses, among …
Measurement technique for real-time and low-cost biosensing using photonic bandgap structures
2011
We present a sensing technique based on using photonic bandgap structures where only the output power is monitored, without the need of tunable sources or spectrum analyzers, thus providing a real-time and low-cost system.
Correcting for non-ignorable missingness in smoking trends
2015
Data missing not at random (MNAR) is a major challenge in survey sampling. We propose an approach based on registry data to deal with non-ignorable missingness in health examination surveys. The approach relies on follow-up data available from administrative registers several years after the survey. For illustration we use data on smoking prevalence in Finnish National FINRISK study conducted in 1972-1997. The data consist of measured survey information including missingness indicators, register-based background information and register-based time-to-disease survival data. The parameters of missingness mechanism are estimable with these data although the original survey data are MNAR. The u…
Spectrum emitted by a trapped electron
2007
We study the behaviour of a homonuclear molecule driven by an intense laser field. Newton's laws are used to describe the dynamics of nuclei while the quantal approach is reserved to the study of the electron. It is observed that the nuclei can oscillate or dissociate according to the degree of ionization of the molecule. In case of low ionization rate it is shown that great amount of information can be obtained by using the simplified approaches of fixed nuclei and of two-state approximation. Under suitable conditions the electron wave function spends a long time localized around one nucleus. The harmonic generation of the molecule is studied and seen to contain even harmonics.
