Three Essays in Economics of Gender

During recent decades, economists' interest in gender-related issues has risen. Researchers aim to show how economic theory can be applied to gender related topics such as peer effect, labor market outcomes, and education. This dissertation aims to contribute to our understandings of the interaction, inequality and sources of differences across genders, and it consists of three empirical papers in the research area of gender economics. The aim of the first paper ("Separating gender composition effect from peer effects in education") is to demonstrate the importance of considering endogenous peer effects in order to identify gender composition effect. This fact is analytically illustrated by employing Manski's (1993) linear-in-means model. The paper derives an innovative solution to the simultaneous identification of endogenous and exogenous peer effects: gender composition effect of interest is estimated from auxiliary reduced-form estimates after identifying the endogenous peer effect by using Graham (2008) variance restriction method. The paper applies this methodology to two different data sets from American and Italian schools. The motivation of the second paper ("Gender differences in vulnerability to an economic crisis") is to analyze the different effect of recent economic crisis on the labor market outcome of men and women. Using triple differences method (before-after crisis, harder-milder hit sectors, men-women) the paper used British data at the occupation level and shows that men suffer more than women in terms of probability of losing their job. Several explanations for the findings are proposed. The third paper ("Gender gap in educational outcome") is concerned with a controversial academic debate on the existence, degree and origin of the gender gap in test scores. The existence of a gap both in mean scores and the variability around the mean is documented and analyzed. The origins of the gap are investigated by looking at wide range of possible explanations.

Role of gender in transthyretin-related amyloidosis: an international perspective based on the Transthyretin Amyloid Outcomes Survey (THAOS)

Background. Transthyretin amyloidosis (ATTR) is an underdiagnosed disease caused by destabilization of transthyretin (TTR) due to pathogenic mutations (ATTRm) or aging (ATTRwt). We explored the role of gender in determining clinical picture using the largest available database on ATTR, the ongoing Transthyretin Amyloid Outcomes Survey (THAOS) international registry. Methods. Data through 1st April 2019 were explored. Symptomatic ATTRm (n=3737), asymptomatic ATTRm (n=644) and ATTRwt (n=874) patients were studied. Results. Male prevalence was 61% in the entire registry, 53% in ATTRm and 95% in ATTRwt. In the overall cohort, cardiac phenotype was more frequent in males (30.7% vs 10.5%, p<0.001). Among ATTRm, 72.3% of patients with amyloidotic cardiomyopathy (ATTR-CM) were males (p<0.001) but echocardiographic features showed no substantial gender differences. Sensory abnormalities (70.1% vs 64.1%, p<0.001), autonomic abnormalities (60% vs 48.5%, p<0.001) and walking disabilities were more frequent among ATTRm males. Carpal tunnel syndrome was more frequent in ATTRm males (18.6% vs 15.5%, p=0.014). In ATTRwt cohort, females had a more pronounced (but anyhow mild) walking disability. Male-to-female ratio varied within genotype, from 0.61 in Val30Met to 11.11 in ATTRwt; furthermore, males’ imbalance was more evident among symptomatic patients rather than in asymptomatic ones. Male gender, age at presentation and specific genotype were independently associated with the presence of ATTR-CM. Conclusions. In ATTR, cardiac involvement is more frequent in men, supporting the hypothesis that some biologic characteristics may “protect” from myocardial amyloid infiltration in women. Further investigations are needed to identify possible underlying protective mechanism and orient the research for innovative, gender-tailored therapeutic approaches.

"Ancestry, gender and language - The role of culture in economic development"

This thesis is a combination of research questions in development economics and economics of culture, with an emphasis on the role of ancestry, gender and language policies in shaping inequality of opportunities and socio-economic outcomes across different segments of a society. The first chapter shows both theoretically and empirically that heterogeneity in risk attitudes can be traced to the ethnic origins and ancestral way of living. In particular, I construct a measure of historical nomadism at the ethnicity level and link it to contemporary individual-level data on various proxies of risk attitudes. I exploit exogenous variation in biodiversity to build a novel instrument for nomadism: distance to domestication points. I find that descendants of ethnic groups that historically practiced nomadism (i) are more willing to take risks, (ii) value security less, and (iii) have riskier health behavior. The second chapter evaluates the nature of a trade-off between the advantages of female labor participation and the positive effects of female education. This work exploits a triple difference identification strategy relying on exogenous spike in cotton price and spatial variation in suitability for cotton, and split sample analyses based on the exogenous allocation of land contracts. Results show that gender differences in parental investments in patriarchal societies can be reinforced by the type of agricultural activity, while positive economic shocks may further exacerbate this bias, additionally crowding out higher possibilities to invest in female education. The third chapter brings novel evidence of the role of the language policy in building national sentiments, affecting educational and occupational choices. Here I focus on the case of Uzbekistan and estimate the effects of exposure to the Latin alphabet on informational literacy, education and career choices. I show that alphabet change affects people's informational literacy and the formation of certain educational and labour market trends.

Well-being, distress and health status in a population of adolescent students

The present work explores the psychosocial issues emerging from a large cross-sectional study aimed to assess the prevalence, clinical manifestations, and psychosocial correlates of hyperandrogenism in a population of Italian high school students. Participants were 1804 adolescents, aged between 15 and 19 years, who volunteered to fill in a package of self-report questionnaires (including the Psychosocial Index, the Symptom Questionnaire and Ryff’s Psychological Well-Being scales for the assessment of psychological aspects) and undergo a comprehensive physical examination. Significant gender differences were found with regard to psychological distress, with females reporting higher scores compared with males, but not on well-being dimensions. The relationships of well-being to distress were found to be complex. Although inversely associated, well-being and ill-being appeared to be distinct domains of mental functioning. The evaluation of the moderating effects of well-being in the association between stress and psychological distress indicated that well-being may act as a protective factor, contributing to less pronounced psychological distress as stress levels increased. Higher rates of somatic complaints were found among current smokers. However, substance use (i.e., smoking and drug use) was also found to be positively associated with some well-being dimensions. A considerable number of participants were found to present with disordered eating symptoms, particularly females, and associated higher stress levels and lower quality of life. Sport activities were found to favourably affect psychological health. As to clinical signs of hyperandrogenism, a significant impairment in psychosocial functioning was found among females, whereas no effects on psychological measures could be detected among males. Subgroups of adolescents with distinct clinical and psychological characteristics could be identified by means of cluster analysis. The present study provides new insights into better understanding of the complex relationships between well-being, distress and health status in the adolescent population, with important clinical implications.

L'intelligenza emotiva in età evolutiva

Emotional Intelligence (EI) has increasingly gained widespread popularity amongst both lay people and scientists in a wide range of contexts and across several research areas. In spite of rigorous inquiry into its applications in educational, social, health and clinical settings, substantial disagreement exists regarding the definition of EI, with respect to both terminology and operationalizations. Actually, there is a consensus about a conceptual distinction between Trait EI, or trait emotional self-efficacy (Petrides & Furnham, 2001), and Ability EI, or cognitive-emotional ability (Mayer & Salovey, 1997). Trait EI is measured via self-report questionnaires, whereas Ability EI is assessed via maximum performance tests. Moreover, EI is the broadest of the emotional constructs, and it subsumes various constructs, as Emotional Awareness (Lane & Schwartz, 1987). To date, EI research has focused primarily on adults, with fewer studies conducted with child samples. The aim of the present study is to investigate the role of different models of EI in childhood and early adolescence (N = 670; 353 females; Mage= 10.25 years ; SD = 1.57). In addition, a further goal is to evaluate the relationship of each construct with personality, non verbal cognitive intelligence, school performance, peer relationships, and affective disorders (anxiety and depression). Results shows significant correlations between Trait EI and Emotional Awareness, whereas Trait and Ability EI appear as independent constructs. We also found significant positive associations between age and Ablity EI and Emotional Awareness (although with add of verbal productivity), while gender differences emerged in favour of females in all EI-related measures. The results provide evidence that Trait EI is partially determined by all of the Big Five personality dimensions, but independent of cognitive ability. Finally, the present study highlights the role of EI on social interactions, school performance and, especially, a negative relationship between Trait EI and psychopathology.

Analisi della relazione tra temperamento, stati psicobiosociali e variabili psicofisiche rispetto ai diversi compiti e strategie metodologiche

L’attività fisica produce effetti benefici a livello mentale (Biddle et al.,2004) e sembra agire sull’emozione modificando attitudini e motivazioni verso la pratica motoria (Digelidis et al., 2003) a partire da sensazioni come il piacere o la noia del fare (Spray et al., 1999). Da questi presupposti il progetto che comprendeva l’analisi di due studi volti a verificare gli effetti dell’attività motoria e sportiva in ambito scolastico, sui comportamenti di adattamento sociale e self efficacy dei bambini. Un terzo studio, di analisi qualitativa, in ambito calcistico, per verificare correlazioni tra orientamento motivazionale genitoriale e comportamenti di adattamento sociale dei figli. Gli strumenti di rilevazione dei livelli di adattamento sociale (Caprara et al, 1992) e self efficacy (Colella, 2008), sono stati somministrati prima e dopo il trattamento delle relative attività motorie mentre, l’orientamento motivazionale dei genitori (Borgogni et al, 2004) è stato rilevato una volta e confrontato con l’adattamento sociale dei figli. Il modulatore del primo studio, l’attività ad alto contenuto emotivo o aggressivo, ha mostrato variazioni significative (p<.05) nei livelli di aggressività fisica-verbale e di comportamento pro sociale tra i 2 gruppi, confermando la letteratura sull’argomento (Pellegrini, in Storch e Roth, 2005; Vaughn, 2005; Tappern e Boulton, 2005). Il modulatore del secondo studio, rappresentato dal giocosport rugby, sempre realizzato nelle ore curricolari di educazione fisica, ha evidenziato differenze significative (p<.05) nell’aumentata self efficacy da parte del gruppo sperimentale, con effetto preponderante sulle femmine rispetto ai maschi. Il terzo studio, descrittivo, ha evidenziato la correlazione tra orientamento motivazionale dei genitori e instabilità emotiva dei figli in risposta a profili genitoriali tendenti alla leadership o al successo nell’ambito lavorativo. I risultati evidenziati mostrano effetti significativi (p<.05), successivi al trattamento, sui comportamenti di adattamento sociale, aggressivo e sulla self efficacy a conferma, della letteratura, sull’importanza di determinate esperienze motorie in età scolare.

Valutazione affettiva del setting odontoiatrico in età evolutiva

Lo studio si pone l'obiettivo di approfondire il tema della valutazione affettiva del setting odontoiatrico in età evolutiva indagando se possa essere modulata da fattori quali: differenze di genere, specifici quadri patologici (Displasia Ectodermica e Patologie Sistemiche Croniche) responsabili di pregresse esperienze odontoiatriche e/o ospedalizzazioni; stato affettivo del bambino, stato affettivo del genitore. Materiali e metodi Studio 1. 85 soggetti [39 (19 maschi e 20 femmine) affetti da PSC e 46 (26 maschi e 20 femmine) soggetti sani] (range di età: 5-14 anni). Sono stati somministrati: un compito di valutazione immagini con 36 immagini (12 a contenuto piacevole, 12 neutro e 12 spiacevole) dallo IAPS e 12 immagini a contenuto odontoiatrico e dei questionari (MCDASf, CFSS-DS, TAD). Studio 2. 45 soggetti (19 maschi affetti da EDs e 26 maschi sani) (range di età: 5-14 anni). Sono stati somministrati: il compito di valutazione immagini precedentemente descritto e i questionari (MCDASf, CFSS-DS, TAD). Studio 3. 104 bambini (64 maschi and 40 femmine) (range di età: 5-14 anni) e uno dei genitori (19 padri and 69 madri). Sono stati somministrati i questionari MCDASf, CFSS-DS, TAD ai bambini e FDPQ, STAI-Y1, Y2-BDI-II ai genitori. Risultati: il contesto odontoiatrico ha una caratterizzazione affettiva distinta rispetto a contesti piacevoli, spiacevoli o neutri; specifici quadri patologici (EDs e PSC) non sembrano modulare il tipo di valutazione affettiva del contesto odontoiatrico; le femmine, attribuiscono al contesto odontoiatrico una valenza significativamente più spiacevole e una maggiore attivazione emotiva rispetto ai maschi; la paura del dolore odontoiatrico del genitore ha una correlazione con l’ansia dei bambini. Conclusione: è importante che l’odontoiatra consideri che la risposta emotiva delle bambine può essere caratterizzata da vissuti di paura con tendenza a comportamenti di allontanamento e valuti se la figura genitoriale rappresenta una risorsa o un elemento disturbante nella corso della seduta stessa.

Trait emotional intelligence: Evidence from italian adolescents and adults

Emotional intelligence (EI) represents an attribute of contemporary attractiveness for the scientific psychology community. Of particular interest for the present thesis are the conundrum related to the representation of this construct conceptualized as a trait (i.e., trait EI), which are in turn reflected in the current lack of agreement upon its constituent elements, posing significant challenges to research and clinical progress. Trait EI is defined as an umbrella personality-alike construct reflecting emotion-related dispositions and self-perceptions. The Trait Emotional Intelligence Questionnaire (TEIQue) was chosen as main measure, given its strong theoretical and psychometrical basis, including superior predictive validity when compared to other trait EI measures. Studies 1 and 2 aimed at validating the Italian 153-items forms of the TEIQue devoted to adolescents and adults. Analyses were done to investigate the structure of the questionnaire, its internal consistencies and gender differences at the facets, factor, and global level of both versions. Despite some low reliabilities, results from Studies 1 and 2 confirm the four-factor structure of the TEIQue. Study 3 investigated the utility of trait EI in a sample of adolescents over internalizing conditions (i.e., symptoms of anxiety and depression) and academic performance (grades at math and Italian language/literacy). Beyond trait EI, concurrent effects of demographic variables, higher order personality dimensions and non-verbal cognitive ability were controlled for. Study 4a and Study 4b addressed analogue research questions, through a meta-analysis and new data in on adults. In the latter case, effects of demographics, emotion regulation strategies, and the Big Five were controlled. Overall, these studies showed the incremental utility of the TEIQue in different domains beyond relevant predictors. Analyses performed at the level of the four-TEIQue factors consistently indicated that its predictive effects were mainly due to the factor Well-Being. Findings are discussed with reference to potential implication for theory and practice.

Influence of optic flow on postural control

The study of optic flow on postural control may explain how self-motion perception contributes to postural stability in young males and females and how such function changes in the old falls risk population. Study I: The aim was to examine the optic flow effect on postural control in young people (n=24), using stabilometry and surface-electromyography. Subjects viewed expansion and contraction optic flow stimuli which were presented full field, in the foveral or in the peripheral visual field. Results showed that optic flow stimulation causes an asymmetry in postural balance and a different lateralization of postural control in men and women. Gender differences evoked by optic flow were found both in the muscle activity and in the prevalent direction of oscillation. The COP spatial variability was reduced during the view of peripheral stimuli which evoked a clustered prevalent direction of oscillation, while foveal and random stimuli induced non-distributed directions. Study II was aimed at investigating the age-related mechanisms of postural stability during the view of optic flow stimuli in young (n=17) and old (n=19) people, using stabilometry and kinematic. Results showed that old people showed a greater effort to maintain posture during the view of optic flow stimuli than the young. Elderly seems to use the head stabilization on trunk strategy. Visual stimuli evoke an excitatory input on postural muscles, but the stimulus structure produces different postural effects. Peripheral optic flow stabilizes postural sway, while random and foveal stimuli provoke larger sway variability similar to those evoked in baseline. Postural control uses different mechanisms within each leg to produce the appropriate postural response to interact with extrapersonal environment. Ageing reduce the effortlessness to stabilize posture during optic flow, suggesting a neuronal processing decline associated with difficulty integrating multi-sensory information of self-motion perception and increasing risk of falls.

Precarious employment and social reproduction: the impact on health and well-being

This dissertation aims to make a theoretical and empirical contribution to the debate on precarious employment, social reproduction and the impact on health and well-being. In recent years, numerous studies have examined the effect of precarious employment as a social determinant on health and well-being, focusing on gender differences in this phenomenon. Within this framework, the research design is to investigate this topic quantitatively in the United Kingdom using longitudinal data to assess the long-term effects of precarious employment and informal care work on health. More specifically, the aim of this thesis is to investigate the impact of precarious employment on health and to analyze gender differences within this phenomenon, particularly in relation to the role of informal care work. The analysis shows that precarious employment is indeed associated to a detrimental effect on health and that this effect is stronger for women’s mental health. Additionally, the analysis shows that time spent on informal care work explains part of the gender gap in mental health, and that informal care and the number of hours spent on it are associated with worse mental health for women. Finally, during the first few months of Covid-19, for both men and women, performing more hours of care work on average is associated with worse mental health, showing that it is not so much the change from fewer to more hours that affects health, but rather those who do more hours on average, hence the long-term effect of being an intensive informal carer.

Differenze di genere tra le caratteristiche cliniche e outcome dei pazienti con cancro ospedalizzati per COVID-19.

Obiettivo: Lo scopo principale di questo studio è analizzare lo sviluppo di complicanze cardiovascolari (CV) nei pazienti con neoplasia e malattia moderata-severa da COVID-19 e valutare differenze di genere per il rischio di mortalità intraospedaliera o di complicanze CV. Materiali e Metodi. Popolazione oggetto di studio. Pazienti inclusi nel registro ISACS-COVID 19 (ClinicalTrials.gov: NCT05188612), dati raccolti a partire da Febbraio 2020 a Luglio 2022. I pazienti arruolati sono stati reclutati da centri ospedalieri di cinque paesi: Italia, Croazia, Macedonia, Serbia e Romania. Le caratteristiche d’inclusione comprendono: età >18 anni, essere ospedalizzati e avere diagnosi certa d’infezione da SARS-CoV2. Gli endpoint analizzati sono stati: mortalità intraospedaliera e lo sviluppo di scompenso cardiaco acuto (SCA) nei pazienti con neoplasia. Risultati. La popolazione finale oggetto dello studio era di 4,014 pazienti ospedalizzati per malattia da COVID-19. Di questi circa l’8% risultava affetto da neoplasia. I pazienti con neoplasia risultavano essere più frequentemente donne (49% vs 40%, p=0.004), con un’età media più alta (68.3±12.95 vs 65.2±15.6, p<0.001) ma con profilo di rischio CV simile ai pazienti liberi da neoplasia. A seguito di analisi logistica di regressione multivariata, le donne non risultavano avere un incremento del rischio di mortalità intraospedaliera (OR 0.83;95%CI 0.66-2.45), mentre la presenza di tumore era significativamente associata ad incremento di mortalità (OR 1.68;95%CI 1.16-2.45). Restringendo le analisi di regressione logistica ai pazienti oncologici, le donne presentavano un incremento del rischio di sviluppo di SC acuto (OR3.07;95%CI 1.14 – 8.30) così come lo era la presenza di tumore al seno (OR 2.26; 95%CI 1.38 – 12.1). Conclusioni. La presenza di neoplasia rappresenta una condizione che incrementa il rischio di mortalità intraospedaliera nei pazienti ricoverati con COVID-19, mentre il genere femminile no. Le donne sembrano avere un rischio aumentato di sviluppo di SC acuto soprattutto se presentano un tumore al seno

Gender equality and human development in Macedonia during transition (1991-2006)

The present thesis treats the issue of gender equality in Macedonia during the period of transition from the socialist system to the one of parliamentary democracy. The main aim is to mainstream the gender perspective in the analysis of the transitional policies through the examination of the basic citizenship rights to which citizens are entitled and by the means of the evaluation of their capabilities to exercise these rights. Gender equality, as one of the main strongholds of the concept of human development is measured through the application of nine gender relevant capabilities in a Case study conducted within selected municipalities in the country. Through the analysis of the Macedonian constitutional and legal framework and the assessment of gender based inequalities, the research questions the need for the enactment of a process of engendering of citizenship, which would integrate gender based differences, contemplate the private sphere of citizens lives and pledge participation in the political life of the country. The thesis, finally, analyses the gender equality strategy of the Macedonian government with the purpose to evaluate whether it is context based, i.e. it tackles the main fields where inequalities emerge and in this context whether it envisages a process of engendering of citizenship.

Understanding Recent Developments in the Turkish Labor Market: Empirical Essays with a Gender Focus

This dissertation comprises three essays on the Turkish labor market. The first essay characterizes the distinctive characteristics of the Turkish labor market with the aim of understanding the factors lying behind its long-standing poor performance relative to its European counterparts. The analysis is based on a cross-country comparison among selected European Union countries. Among all the indicators of labor market flexibility, non-wage cost rigidities are regarded as one of the most important factors in slowing down employment creation in Turkey. The second essay focuses on an employment subsidy policy which introduces a reduction in non-wage costs through social security premium incentives granted to women and young men. Exploiting a difference-in-difference-in differences strategy, I evaluate the effectiveness of this policy in creating employment for the target group. The results, net of the recent crisis effect, suggest that the policy accounts for a 1.4% to 1.6% increase in the probability of being hired for women aged 30 to 34 above men of the same age group in the periods shortly after the announcement of the policy. In the third essay of the dissertation, I analyze the labor supply response of married women to their husbands' job losses (AWE). I empirically test the hypothesis of added worker effect for the global economic crisis of 2008 by relying on the Turkey context. Identification is achieved by exploiting the exogenous variation in the output of male-dominated sectors hard-hit by the crisis and the gender-segmentation that characterizes the Turkish labor market. Findings based on the instrumental variable approach suggest that the added worker effect explains up to 64% of the observed increase in female labor force participation in Turkey. The size of the effect depends on how long it takes for wives to adjust their labor supply to their husbands' job losses.
