The Contribution of Proportional Taxes and Tax-Free Cash Benefits to Income Redistribution over the Period 2005-2018: Evidence from Italy
Over the last two decades a growing interest in understanding what determines the redistributive role of tax-benefit systems has emerged worldwide. In the case of Italy, previous analyses were mainly focused on quantifying the contribution of marginal tax rates, deductions and tax credits to the redistributive capacity of personal income tax (PIT), while neglecting the effect on income redistribution of proportional taxes and income sources exempt from taxation such as tax-free cash benefits. This paper aims to fill this gap by applying two alternative Gini-based decomposition methodologies (Onrubia et al., 2014; Urban, 2014) to the redistributive effects of the Italian taxbenefit system over the period 2005-2018. The contribution of each tax-benefit instrument is quantified for several scenarios which diverge from each other in that they are representative of different degrees of extension of the tax-benefit system under examination
Using Simple Neural Networks to Correct Errors in Optical Data Transmission.
We have demonstrated the applicability of
neural-network-based systems to the problem
of reducing the effects of signal distortion,
and shown that such a system has the potential
to reduce the bit-error-rate in the digitized
version of the analogue electrical signal
derived from an optical data stream by a
substantial margin over existing techniques
The Struggle of Being Poor and Claimant: Evidence on the Non-Take-Up of Social Policies in Italy
Social policies aim to alleviate poverty and income inequality, providing cash benefits and services to households facing economic difficulties. Nonetheless, it is well known that a relevant portion of eligible households do not claim such policies. Through an original methodology based on ISEE (Indicatore della Situazione Economica Equivalente) administrative records, this paper offers the first empirical evidence on the non-take-up of social policies in Italy. We show that roughly 1.1 million of poor households did not file the ISEE declaration in 2018, a necessary step to claim most means-tested cash benefits and services. Based on multinomial logit regressions, results show that younger and larger households are more inclined to claim social policies. In contrast, households headed by a female or migrant tend to report severe levels of non-take-up, as do those living in the islands
A 6 kV–150 A, 8 ns rise time pulse generator for excitation of ferroelectric cathodes
A pulse generator with the following characteristics is presented: the voltage ranges in the interval 0.1–6 kV, the maximum delivered current is 150 A, the pulse length ranges within the interval 100–300 ns, the rise time and the decay times are, respectively, 10 and 25 ns on 50 Ω resistive load and the repetition rate is higher than 1 MHz. The circuit has a source capacitor of 10 nF charged at the needed voltage, the capacitor feeds the load through a parallel of two fast and high voltage solid state switches. The nanosecond rise time and the square fashion of the pulse have been accomplished arranging all the components in cylindrical symmetry. A bipolar pulse is obtained coupling two circuits with opposite polarity
Optimisation of micro-structured waveguides in lithium niobate (z-cut)
We present an optimization procedure to improve the propagation properties of the depressed cladding, buried micro-structured waveguides formed in a z-cut lithium niobate (LN) crystal by high repetition rate femtosecond (fs) laser writing. It is shown that the propagation wavelength for which the confinement losses of ordinary (O) and extraordinary ordinary (E) polarizations are below 1 dB/cm can be optimized beyond 3 micro meter for hexagonal WG structures with seven rings of tracks
Report 1 PHIN-CARE-JRA2-WP3 Second Task: Pulse Shaping
This report presents the activity developed on laser pulse shaping argument in years 2004-2005 by Milano-INFN within the framework of CARE /JRA2 \Charge production with Photoinjectors"
second task \Pulse Shaping". A dedicated laser system with the relative diagnostic
tools have been developed. A liquid crystal programmable spatial light modulator(LCP-SLM)
shaper have been studied and set for the generation of di®erent waveforms. The shaper is
integrated in the laser system for an automatic generation of the target waveforms via the
insetion of a computer which drives the system through the developed software. The system
can be programmed to generate any target waveform compatible with the spectral bandwidth
of the laser system and some exemples are presented. The following issues are treated: (i)
the operation stability as function of perturbations of the set-up parameters, (ii) the design
of the shaper for the SPARC project, (iii) a new shaper concept for the generation of long
target waveforms and (iiii) the rectangular pulse generation at the second harmonic
