An Online Time Warping based Map Matching for Vulnerable Road Users’ Safety
2018
International audience; High penetration rate of Smartphones and their increased capabilities to sense, compute, store and communicate have made the devices vital components of intelligent transportation systems. However, their GPS positions accuracy remains insufficient for a lot of location-based applications especially traffic safety ones. In this paper, we developed a new algorithm which is able to improve smartphones GPS accuracy for vulnerable road users' traffic safety. It is a two-stage algorithm: in the first stage GPS readings obtained from smartphones are passed through Kalman filter to smooth deviated reading. Then an adaptive online time warping based map matching is applied to…
Households' Balance Sheets and the Effect of Fiscal Policy
2022
Using households' balance-sheet composition in the Panel Survey of Income Dynamics, we identify six household types. Since 1999, there has been a decline in the share of patient households and an increase in the share of impatient households with negative wealth. Using a six-agent New Keynesian model with search and matching frictions, we explore how changes in households' shares affect the transmission of government spending shocks. We show that the relative share of households in the left tail of the wealth distribution plays a key role in the aggregate marginal propensity to consume, the magnitude of fiscal multipliers, and the distributional consequences of government spending shocks.

Selection bias, incentivi alle imprese e sviluppo locale: Una valutazione ex-post
2015
Questo lavoro si concentra sulla valutazione di un programma di aiuti alle imprese facente parte di un piu vasto programma per lo sviluppo locale realizzato in Italia durante il ciclo di programmazione comunitaria 2000-2006. Esso costituisce un approfondimento di una precedente analisi (Cusimano, Mazzola, 2014) di valutazione ex-post degli effetti dei regimi di aiuto previsti nell’ambito dei progetti integrati territoriali (pit), e mira ad identificare l’eventuale presenza di distorsione da selezione (selection bias) nella quantificazione dell’efficacia della politica. Mediante un’analisi empirica effettuata per mezzo di diverse metodologie basate sul propensity score matching (psm) viene m…
Employment protection : its effects on different skill groups and on the incentive to become skilled
2005
Summary Employment protection affects labour market outcomes and hence the incentive to acquire skills. Using a matching model with two education levels in which workers decide ex-ante on their skill formation, it is shown that employment protection can raise the fraction of skilled workers. This will be the case if workers obtain a sufficiently large fraction of the rent created by skill formation. Furthermore, it will be shown that high-skilled workers face shorter unemployment duration and lower dismissal probabilities.
Schools opening and Covid-19 diffusion: Evidence from geolocalized microdata
2021
Are schools triggering the diffusion of the Covid-19? This question is at the core of an extensive debate about the social and long-run costs of stopping the economic activity and human capital accumulation from reducing the contagion. In principle, many confounding factors, such as climate, health system treatment, and other forms of restrictions, may impede disentangling the link between schooling and Covid-19 cases when focusing on a country or regional-level data. This work sheds light on the potential impact of school opening on the upsurge of contagion by combining a weekly panel of geocoded Covid-19 cases in Sicilian census areas with a unique set of school data. The identification o…
Re-examining the migration–trade link using province data: An application of the generalized propensity score
2013
Abstract The migration–trade link has been studied extensively since the mid nineties, finding a positive impact through different channels. Based on the generalized propensity score (GPS) methodology, we estimate a dose–response function, depicting a non-linear impact of immigration on exports using province data for Spain and Italy. For both countries the response of province exports to more immigrants from a given nationality is always positive, although varies with the level of immigrants. First we find neither minimum threshold nor exhaustion point in the effectiveness of the immigration networks on province exports. Second we find that the value of the potential bilateral exports reac…
Heterogeneidad en el impacto de la política de becas en la escolaridad secundaria postobligatoria en España: un análisis por subgrupos poblacionales
2013
El presente trabajo analiza el impacto de las becas sobre la probabilidad de finalizar con éxito el nivel secundario postobligatorio en España en el caso de diferentes subgrupos poblacionales. Se aplica un diseño cuasiexperimental (Propensity score matching) a partir de la Encuesta de Condiciones de Vida (ECV-2006). Los resultados confirman la existencia de efectos diferenciales positivos (con relación al impacto medio) de la política educativa en el caso de las mujeres y de los alumnos provenientes de hogares desfavorecidos, demostrando la existencia de heterogeneidad en el impacto de la política analizada.
Regional Matching Frictions and Aggregate Unemployment
2006
This study demonstrates that a stochastic frontier approach applied to regional level data offers a convenient and interesting method to examine how regional differences in matching efficiency and structural factors contribute to aggregate unemployment. The study reveals notable and temporally stable differences in matching efficiency across travel-to-work areas in Finland. If all areas were as efficient as the most efficient one, the number of hirings would increase by about 40 per cent. This would reduce the aggregate unemployment rate from the current 8.5 per cent level to 6.0 per cent. If all the areas shared the same structural characteristics as the most favourable area, the aggregate…
The Effect of Corrective Feedback on Performance in Basic Cognitive Tasks: An Analysis of RT Components
2016
[EN] The current work examines the effect of trial-by-trial feedback about correct and error responding on performance in two basic cognitive tasks: a classic Stroop task (n = 40) and a color-word matching task (n = 30). Standard measures of both RT and accuracy were examined in addition to measures obtained from fitting the ex-Gaussian distributional model to the correct RTs. For both tasks, RTs were faster in blocks of trials with feedback than in blocks without feedback, but this difference was not significant. On the other hand, with respect to the distributional analyses, providing feedback served to significantly reduce the size of the tails of the RT distributions. Such results sugge…
La conoscenza delle emozioni in età prescolare: un contributo alla validazione italiana dell’Emotion Matching Task (EMT)
2013
Lo studio presenta i dati relativi alla validità di criterio dell’EMT (Izard et al., 2003), una misura della conoscenza delle emozioni in età prescolare. La validità di criterio è esaminata in relazione alla regolazione emotiva dei bambini, alla loro competenza sociale e alla manifestazione di problemi comportamentali di natura internalizzata ed esternalizzata. I dati sono preliminarmente analizzati in funzione dell’età e delle abilità verbali. Hanno partecipato allo studio 120 bambini, divisi in tre gruppi: 3, 4 e 5 anni. Oltre all’EMT, sono stati somministrati il PPVT (Dunn e Dunn, 1997; Stella, Pizzoli e Tressoldi, 2000), l’ERC (Molina et al., 2014; Shields e Cicchetti, 1997) e l’SCBE (L…
