    From SHIW to IT-SILC: construction and representativeness of the new CAPP_DYN first-year population

    This paper describes the construction of the initial population in CAPP_DYN and illustrates the degree of representativeness of the Italian population in 2006. While the previous version of the model was constructed using the Bank of Italy Survey on Household Income and Wealth, the current version is based on the new ISTAT Survey on Income and Living Conditions. The first part of the paper discusses the reasons that led us to this switch. It also provides full details on the operations carried out on the original dataset in order to obtain a sample that can be used as the first year population of the Dynamic Simulation Model. In the second part of the paper, the demographic and socio-economic characteristics of the initial population sample are compared with information coming from other sources, such as administrative archives, national accounts and Labour Force Surveys. This exercise is crucial in assessing the capability of CAPP_DYN to represent the population's characteristics at the starting point.Dynamic micro-simulation, model validation, income distribution, pensions and social security

    Estimation and Simulation of Earnings in IT-SILC

    This paper describes income distribution among workers in Italy using both the cross-sectional and panel component of IT-SILC. We highlight advantages and drawbacks of different econometric approaches, comparing standard OLS estimates with those obtained from Random Effects and Poisson Maximum Likelihood and assessing whether the results are sensitive to the different specification. Finally, we present the procedure in use in simulating future earnings in CAPP_DYN, the dynamic population-based microsimulation model of the CAPPMicrosimulation; Earnings; Lifetime; Inequality; IT-SILC

    Getting stable: an evaluation of the incentives for permanent contracts in Italy

    Get PDF
    There is little evidence as to the effectiveness of incentives for the conversion of fixed-term contracts into permanent jobs. We aim at filling this gap by studying a recent Italian program which provides benefits for employers who convert contracts for workers in specific demographic groups (females, younger men). Due to funding constraints, the incentives were available only for a few days, allowing us to employ a difference-in-differences strategy between similar short periods. Using administrative microdata for the Veneto region, we show that the subsidy increased conversions by 83% on average, with no substitution effects over time or across groups of workers.

    Lentil Fortification and Non-Conventional Yeasts as Strategy to Enhance Functionality and Aroma Profile of Craft Beer

    During the last few years, consumer demand has been increasingly oriented to fermented foods with functional properties. This work proposed to use selected non-conventional yeasts (NCY) Lachancea thermotolerans and Kazachstania unispora in pure and mixed fermentation to produce craft beer fortified with hydrolyzed red lentils (HRL). For this, fermentation trials using pils wort (PW) and pils wort added with HRL (PWL) were carried out. HRL in pils wort improved the fermentation kinetics both in mixed and pure fermentations without negatively affecting the main analytical characters. The addition of HRL determined a generalized increase in amino acids concentration in PW. L. thermotolerans and K. unispora affected the amino acid profile of beers (with and without adding HRL). The analysis of by-products and volatile compounds in PW trials revealed a significant increase of some higher alcohols with L. thermotolerans and ethyl butyrate with K. unispora. In PWL, the two NCY showed a different behavior: an increment of ethyl acetate (K. unispora) and beta-phenyl ethanol (L. thermotolerans). Sensory analysis showed that the presence of HRL characterized all beers, increasing the perception of the fruity aroma in both pure and mixed fermentation

    A First Search for coincident Gravitational Waves and High Energy Neutrinos using LIGO, Virgo and ANTARES data from 2007

    Get PDF
    We present the results of the first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are not observed by conventional photon astronomy, particularly at high energy. Our search uses neutrinos detected by the underwater neutrino telescope ANTARES in its 5 line configuration during the period January - September 2007, which coincided with the fifth and first science runs of LIGO and Virgo, respectively. The LIGO-Virgo data were analysed for candidate gravitational-wave signals coincident in time and direction with the neutrino events. No significant coincident events were observed. We place limits on the density of joint high energy neutrino - gravitational wave emission events in the local universe, and compare them with densities of merger and core-collapse events.Comment: 19 pages, 8 figures, science summary page at http://www.ligo.org/science/Publication-S5LV_ANTARES/index.php.

    Essays in family and labour economics

    In the first chapter I estimate the effect of providing unpaid care to adults on caregivers' employment; with data from the European Community Household Panel. Using the presence of disabled individuals inside the household as an' instrument for caregiving, I found that the negative effect on employment is magnified with respect to OL8. However, when individual time constant heterogeneity is accounted for using within group regressions, the estimated negative effect is smaller and the use of instruments does not make a difference. In the second I discuss a theoretical model for the distance at which adult children decide to live with respect to their parents. The main result from previous research (Konrad et al, 2002) was that siblings tend to live at different locations, with the first born moving far away in order to leave to the youngest the burden of elderly care. I added a stage in which adult children may need help from their parents with their own young offspring. I found that symmetric equilibria may arise, where siblings locate at the same distance in order to share elderly care and benefit jointly from (grand)child care. In the third I estimate the causal effect of retirement on house work, using the 2007 Italian Survey of Income and Living Conditions. At any age, ret irees and workers may have different preferences on leisure and home production. Therefore a simple comparison of them would not give us the quantity of interest. Differently, I exploited the fact that a large fraction of individuals go into retirement as soon as eligible for a pension. In a Fuzzy Regression Discontinuity Design, I compared individuals close to eligibility to those who just met the requirements. I found an increase for women by 430 minutes/week, while there is no evidence of such an effect for men.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    No free lunch, buddy: past housing transfers and informal care later in life

    No full text
    Previous empirical literature on the relation between intergenerational transfer of assets and services has mostly focused on contemporary exchanges. By contrast, we provide novel evidence showing that parents who helped their adult children in the past are rewarded by higher chances of receiving informal care later in life. To this end we use Italian data containing precise retrospective information about the help with housing that couples received from their parents when they got married, such as a real estate donation or down payment. Our estimates show that this type of past help is positively associated with the current provision of informal care to the parents. This result is robust to controlling for a large set of individual and family characteristics and is only partially due to increased geographical proximity. We suggest that this finding can be explained by mixed self-interest motives, related to theories based on either bilateral exchange or the presence of a third generation (grandchildren), such as the demonstration effect model or the family constitution model
