Hang up on stereotypes: Domestic violence and an anti‐abuse helpline campaign

We estimate the effectiveness of a government-led anti-domestic-abuse campaign launched in the midst of the covid-19 pandemic on the number of calls to the Italian domestic violence helpline. In the week after the start of the campaign, we document a sharp increase in the number of calls. By exploiting geographical variation in the exposure to the campaign ads aired on public TV networks, we find that greater exposure is associated with an increase in the number of calls after the launch of the campaign. However, the effectiveness of the media campaign is hindered in areas where gender stereotypes are stronger

Does democracy cause growth? A meta-analysis perspective

The relationship between democracy and economic growth has long been investigated both in the political science and in the economic literature with inconclusive outcomes. By adopting a multi-level meta-analysis framework, we tried to shed lights on this conundrum. Our hierarchical sample includes 103 studies containing 942 point-estimates. Our random effects model suggests that the sign of this relationship, albeit positive, is statistically weak. We then address the high between-studies heterogeneity by adopting meta-regression analysis models. Results are striking: the effect sizes\u2019 variance is largely driven by spatial and temporal differences in the samples, indicating that the democracy and growth nexus is not homogeneous across world regions and time periods. Conversely, the large number of control variables included in the papers, do not impact the reported results. At the same time, models estimated by means of the within estimator have a significant, albeit negative, impact on economic growth. This seems to suggest that scholars have not yet found the appropriate control variables - or their suitable proxies - to explain such widely debated relationship

Does democracy cause growth? A meta-analysis (of 2000 regressions)

The relationship between democracy and economic growth has been widely debated in the social sciences with contrasting results. We apply a meta-analytical framework surveying 188 studies (2047 models) covering 36 years of research in the field. We also compare the effect of democracy on growth with the effect of human capital on growth in a sub-sample of 111 studies (875 models). Our findings suggest that democracy has a positive and direct effect on economic growth beyond the reach of publication bias, albeit weaker (about one third) of that of human capital. Further, the growth effect of democracy appears to be stronger in more recent papers not surveyed in Doucouliagos and Uluba\u15fo\u11flu (2008). Finally, we show that the heterogeneity in the reported results is mainly driven by spatial and temporal differences in the samples, indicating that the democracy and growth nexus is not homogeneous across world regions and decades

An increase in the levels of middle surface antigen characterizes patients developing HBV-driven liver cancer despite prolonged virological suppression

: Hepatitis B virus (HBV) contains three surface glycoproteins-Large-HBs (L-HBs), Middle-HBs (M-HBs), and Small-HBs (S-HBs), known to contribute to HBV-driven pro-oncogenic properties. Here, we examined the kinetics of HBs-isoforms in virologically-suppressed patients who developed or did not develop hepatocellular carcinoma (HCC). This study enrolled 30 chronically HBV-infected cirrhotic patients under fully-suppressive anti-HBV treatment. Among them, 13 patients developed HCC. Serum samples were collected at enrolment (T0) and at HCC diagnosis or at the last control for non-HCC patients (median (range) follow-up: 38 (12-48) months). Ad-hoc ELISAs were designed to quantify L-HBs, M-HBs and S-HBs (Beacle). At T0, median (IQR) levels of S-HBs, M-HBs and L-HBs were 3140 (457-6995), 220 (31-433) and 0.2 (0-1.7) ng/mL. No significant differences in the fraction of the three HBs-isoforms were noticed between patients who developed or did not develop HCC at T0. On treatment, S-HBs showed a >25% decline or remained stable in a similar proportion of HCC and non-HCC patients (58.3% of HCC- vs. 47.1% of non-HCC patients, p = 0.6; 25% of HCC vs. 29.4% of non-HCC, p = 0.8, respectively). Conversely, M-HBs showed a >25% increase in a higher proportion of HCC compared to non-HCC patients (50% vs. 11.8%, p = 0.02), in line with M-HBs pro-oncogenic role reported in in vitro studies. No difference in L-HBs kinetics was observed in HCC and non-HCC patients. In conclusion, an increase in M-HBs levels characterizes a significant fraction of HCC-patients while under prolonged HBV suppression and stable/reduced total-HBs. The role of M-HBs kinetics in identifying patients at higher HCC risk deserves further investigation

Localisation of gamma-ray bursts from the combined SpIRIT+HERMES-TP/SP nano-satellite constellation

Multi-messenger observations of the transient sky to detect cosmic explosions and counterparts of gravitational wave mergers critically rely on orbiting wide-FoV telescopes to cover the wide range of wavelengths where atmospheric absorption and emission limit the use of ground facilities. Thanks to continuing technological improvements, miniaturised space instruments operating as distributed-aperture constellations are offering new capabilities for the study of high energy transients to complement ageing existing satellites. In this paper we characterise the performance of the upcoming joint SpIRIT + HERMES-TP/SP nano-satellite constellation for the localisation of high-energy transients through triangulation of signal arrival times. SpIRIT is an Australian technology and science demonstrator satellite designed to operate in a low-Earth Sun-synchronous Polar orbit that will augment the science operations for the equatorial HERMES-TP/SP. In this work we simulate the improvement to the localisation capabilities of the HERMES-TP/SP when SpIRIT is included in an orbital plane nearly perpendicular (inclination = 97.6$^\circ$) to the HERMES orbits. For the fraction of GRBs detected by three of the HERMES satellites plus SpIRIT, the combined constellation is capable of localising 60% of long GRBs to within ~ 30 deg$^2$ on the sky, and 60% of short GRBs within ~ 1850 deg$^2$. Based purely on statistical GRB localisation capabilities (i.e., excluding systematic uncertainties and sky coverage), these figures for long GRBs are comparable to those reported by the Fermi GBM. Further improvements by a factor of 2 (or 4) can be achieved by launching an additional 4 (or 6) SpIRIT-like satellites into a Polar orbit, which would both increase the fraction of sky covered by multiple satellite elements, and enable $\geq$ 60% of long GRBs to be localised within a radius of ~ 1.5$^\circ$ on the sky.Comment: 17 pages, 10 figures, 1 table.

Beyond averages - Fairness in an economy that works for people

Growing disparities on multiple socio-economic dimensions have contributed to a sense of unfairness and discontent in Europe. Fairness is a subjective phenomenon, but the far-reaching consequences of perceptions of unfairness warrant a closer look at its drivers and underlying dynamics. The report, written before the outbreak of the COVID-19 pandemic, analyses some of the most pertinent dimensions of fairness in relation to the agenda for a fair, inclusive and social European Union. Income inequality, educational inequality and the challenges facing existing welfare state arrangements are discussed from a pre-crisis perspective. Thus, the report gives a snapshot of the state of fairness in Europe before the COVID-19 outbreak and provides a benchmark against which some of the consequences of the current situation can be evaluated.JRC.I.1-Monitoring, Indicators & Impact Evaluatio

META-ANALYSIS AND META-REGRESSION ANALYSIS IN ECONOMICS: METHODOLOGY AND APPLICATIONS

A partire dagli anni ’80, la diffusione dei metodi statistici, abbinata ai progressi nelle capacità computazionali dei personal computers, ha progressivamente facilitato i ricercatori nel testare empiricamente le proprie teorie. Gli economisti sono diventati in grado di eseguire milioni di regressioni prima di pranzo senza abbandonare le proprie scrivanie. Purtroppo, ciò ha portato ad un accumulo di evidenze spesso eterogenee, quando non contradditorie se non esplicitamente in conflitto. Per affrontare il problema, questa tesi fornirà una panoramica dei metodi meta-analitici disponibili in economia. Nella prima parte verranno introdotte le intuizioni alla base dei modelli gerarchici a fattori fissi e casuali capaci di risolvere le problematicità derivanti dalla presenza di osservazioni non indipendenti. Verrà inoltre affrontato il tema dell’errore sistematico di pubblicazione in presenza di elevata eterogeneità tra gli studi. La metodologia verrà successivamente applicata, nella seconda e terza parte, a due diverse aree della letteratura economica: l’impatto del rapporto banca-impresa sulle prestazioni aziendali e il dibattito sulla relazione fra democrazia e crescita. Mentre nel primo caso la correlazione negativa non è influenzata da fattori specifici ai singoli paesi, il contrario è vero per spiegare l’impatto (statisticamente non significativo) delle istituzioni democratiche sullo sviluppo economico. Quali siano questi fattori è però meno chiaro; gli studiosi non hanno ancora individuato le co-variate – o la corretta misurazione di esse – capaci di spiegare questa discussa relazione.Starting in the late 1980s, improved computing performances and spread knowledge of statistical methods allowed researchers to put their theories to test. Formerly constrained economists became able [to] run millions of regressions before lunch without leaving their desks. Unfortunately, this led to an accumulation of often conflicting evidences. To address such issue, this thesis will provide an overview of the meta-analysis methods available in economics. The first paper will explain the intuitions behind fixed and random effects models in such a framework. It will then detail how multilevel modelling can help overcome hierarchical dependence issues. Finally, it will address the problem of publication bias in presence of high between-studies heterogeneity. Such methods will be then applied, in the second and third papers, to two different areas of the economics literature: the effect of relationship banking on firm performances and the democracy and growth conundrum. Results are far-reaching. While in the first case the documented negative relation is not driven by country-specific characteristics the opposite is true for the (statistically insignificant) impact of democratic institutions on economic growth. What these characteristics are is, however, less clear. Scholars have not yet found the covariates - or their suitable proxies - that matter to explain such much-debated relationship

Intergenerational mobility in the Netherlands: models, outcomes and trends

We reconstruct the genealogical tree of all individuals ever appearing in Dutch municipalities records starting in 1995. Combining microdata from tax authorities with education records we compute a measure of permanent income as well as education. We estimate the degree of intergenerational persistence in education and income in the population and across time, showing that it is higher than what previous estimates would suggest, albeit it appears to be decreasing. Finally, exploiting information on the education of grandparents, we estimate a model of intergenerational mobility in which endowments are transmitted through a latent factor. Estimates suggest an even higher persistence

The Median Voter Takes it All: Preferences for Redistribution and Income Inequality in the EU-28

The relation between income inequality and support for redistributive policies has long being debated by social scientists, albeit with mostly contrasting findings. We shed light on this puzzle by exploiting a novel EU-28 wide survey (Eurobarometer 471) and matching it with an array of regional and national inequality measures. Using binary choice models, we show that support for redistribution is positively linked with the level of income inequality. The same association is found for perceptions of inequality being too high. In addition, we exploit alternative proxies of socio-economic status as well as subjective beliefs about fairness in the society. We document that individuals believing to be at the top of the social ladder, as well as people considering equal opportunities to be in place, are less supportive of government intervention to reduce inequalities. Our results are robust to different measures of inequalities, additional controls as well as a cross-validation with a widely recognized survey (ESS). We conclude that for the planning of policies based on social preferences, inequality matters.JRC.B.1-Finance and Econom
