The effects of public sector employment on household savings and labor supply

AbstractIn many countries, the structure of wages and the labor law legislation are completely different for public and private sector employees. In this paper, we develop a general equilibrium overlapping generations model to study the effect of such differences on household savings and labor supply. To conduct our analysis, first we use microdata from two Brazilian household surveys to document that civil servants save and work significantly less than their counterparts in the private sector. Second, we use matched employer–employee microdata from Brazil (RAIS) to document differences between the two sectors in terms of wage and unemployment risk. Then, we calibrate the model to be consistent with micro and macro evidence for Brazil. Our counterfactual exercises show that differences in wages characteristics and labor law legislation account for nearly 70% of the gap in savings between civil servants and private sector workers, and 57% of the gap in labor supply. In addition, we find that eliminating those differences can produce sizable increase on aggregate savings, employment, and welfare.

The impact of childcare centres' closures due to COVID-19 on women's labour supply

PurposeThis paper evaluates the short-term impact of childcare centres' closures, due to COVID-19 restrictions, on Brazilian mothers' labour force participation and employment rates.Design/methodology/approachFormal education is non-mandatory according to Brazilian law until the age of four, allowing the identification of children that attend childcare centres and of those that do not attend. Using data from the Brazilian Household Survey, PNAD Contínua/IBGE, the authors construct a two-period panel with women sampled in the second quarter of 2019 and 2020. The authors apply propensity score matching and differences-in-differences methods to control selection into treatment.FindingsThe results show a negative impact in terms of employment for mothers whose children attended a childcare centre before the COVID-19 pandemic. But there was no impact in terms of labour force participation rates. Investigating heterogeneous effects associated with childcare centres' closures, the authors find that women with fewer years of schooling, with children aged two or three years old and located in urban areas, suffered greater penalties in the labour market due to the closure of childcare centres.Originality/valueFew studies could distinguish the pandemic effects directly associated with childcare centres' closures. The paper is the first to analyse the Brazilian case, undertaking an original approach to handle the problem of selection bias. The results help identify the most vulnerable groups of women in the labour market, shedding light on the importance of childcare centres on women's labour supply and of compensating mechanisms to serve as protection during the crisis.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-11-2022-0748.

Physical violence against women in Brazil: Findings from the 3rd Brazilian household survey on substance use

ABSTRACT Brazil has a historical gap regarding information on violence against women. Herein we aimed to evaluate the association of socioeconomic and demographic characteristics with physical violence against women in Brazil, as well as the possible escalation of violence to severe patterns of violence. We analysed data from the 3rd Brazilian Household Survey on Substance Use, in 2015. The main outcomes were reporting any physical violence and being stabbed/shot in the last 12-months. Logistic regressions were fitted to assess the association between socioeconomic and demographic variables with the outcomes. We estimated 3.8 million women reported any physical violence (5.52%): 3.79% reported threats to beat/ push/kick, 1.87% threats with knife/gun, 2.49% were beaten/pushed/kicked, 0.63% were spanked/ choked, and 0.21% were stabbed/shot. The higher the severity of violence, the higher the number of types of violence experienced. The likelihood of reporting any violence was higher among women 18–24 years, without a stable partner, who were at an informal job or unemployed, and who live in urban areas. The sociodemographic characteristics associated with reporting any violence reinforce the importance of addressing gender inequalities. Evidence of escalation violence reinforces the need to protect and care for women who report any type of violence.

Would the Brazilian population support the alcohol policies recommended by the World Health Organization?

ABSTRACTOBJECTIVE To evaluate the support of the Brazilian population to the alcohol-policies proposed by the World Health Organization to decrease alcohol harm (specifically: to decrease alcohol availability and advertising, and to increase pricing). In addition, we evaluated the factors associated with being against those policies.METHODS Data from 16,273 Brazilians, aged 12–65 years, interviewed in the 3rd Brazilian Household Survey on Substance Use (BHSU-3) were analyzed. The BHSU-3 is a nationwide, probability survey conducted in 2015. Individuals were asked if they would be against, neutral, or in favor of seven alcohol policies grouped as: 1) Strengthen restrictions on alcohol availability; 2) Enforce bans or restrictions on alcohol advertising, sponsorship, and promotion; and 3) Raise prices on alcohol through excise taxes and pricing. Generalized linear models were fitted to evaluate factors associated with being against each one of those policies and against all of policies.RESULTS Overall, 28% of the Brazilians supported all the above mentioned policies, whereas 16% were against them. The highest rate of approval refers to restricting advertising (53%), the lowest refers to increasing prices (40%). Factors associated with being against all policies were: being male (AOR = 1.1; 95%CI: 1.0–1.3), not having a religion (AOR = 1.4; 95%CI: 1.1–1.8), being catholic (AOR = 1.3; 95%CI: 1.1–1.5), and alcohol dependence (AOR = 1.6; 95%CI: 1.1–2.4).CONCLUSIONS The Brazilian government could count on the support of most of the population to restrict alcohol advertising. This information is essential to tackle the lobby of the alcohol industry and its clever marketing strategy.

The China Shock Impact on Labor Informality: The Effects on Brazilian Manufacturing Workers

The vigorous growth of the Chinese economy together with its increasingly successful role in international trade may have profoundly impacted developing countries. This study examines the large increase in the international trade exposure of the Brazilian economy during 2000–2012 to assess the impacts of import competition on its manufacturing formal and informal labor markets. In this period, import penetration grew by more than 20 percent in Brazil, and the share of the import penetration originating in China increased from 3 to 20 percent. At the same time, the share of informal workers in manufacturing declined from 27 to approximately 15 percent. Employing a switching regression model and Brazilian household survey data, this study finds that a greater industry-level Chinese and ‘rest of the world’ import penetration increases the likelihood of jobs becoming informal at different intensities, and these effects are smaller in unskilled-labor intensive industries and manufacturing states. Additionally, both types of import penetration positively impact the average informal wage. In contrast, the estimates suggest that a larger Chinese import penetration reduces average formal wages, while imports from elsewhere have the opposite effect. The results also indicate that the magnitude of the effects on wages are moderated by the unskilled labor intensity of the industry and whether the worker is located in a manufacturing state.

Understanding alcohol-related indicators from population surveys: answering the "Five W's of Epidemiology".

The harmful use of alcohol is a major risk factor for the global burden of disease, and public policies are the most effective strategies to prevent it. Population-based surveys are milestones for planning, implementing, and monitoring those policies. However, there are numerous ways to measure alcohol consumption which may result in different indicators. Researchers and stakeholders should find common ground in the understanding of these measures to avoid misinterpretation and confusion in the field. Answering to the "Five W's Epidemiology", when interpreting alcohol-related information, may improve the communication, as well as reproducibility and comparability of research findings. This paper aims to exemplify this approach by describing some indicators from the World Health Organization's Global Information System on Alcohol and Health (GISAH) and the corresponding data available from the latest Brazilian household surveys. Notably, none of the Brazilian surveys reports on all the nine selected GISAH indicators, and only two provided the necessary methodological details to be fully reproducible. A stronger agenda is of the utmost importancefor advancing in the monitoring and prevention of alcohol-related harms in Brazil.

Racial Democracy and Black Victimization in Brazil

The main objective of this study is to quantify racial victimization differential between Blacks and Whites in Brazil, focusing on homicides and physical assaults. Combining socioeconomic data from the Brazilian Household Survey with data from the Mortality Information System, we apply the Oaxaca–Blinder decomposition to isolate the racial discrimination component from the social indicators correlated with homicides and physical assaults. Findings indicate that only part of the victimization differential between Blacks and Whites is explained by structural attributes. A significant portion of this differential (at least 40%) for both homicides and physical assaults persists as evidence of racial discrimination. In addition, both for homicides and physical assaults, a more discriminatory scenario is observed in the North and Northeast regions of Brazil, regions historically characterized by higher social inequalities and violent mortality.

Cannabis Consumption Onset and Addiction: Data from the Second Brazilian Drugs and Alcohol Survey (BNADS)

ABSTRACT The objective of this study was to provide rates of cannabis use and dependence and risk factors, proposing a conditional path model for cannabis addiction. A subsample of adult participants from a Brazilian household survey was analyzed to estimate cannabis dependence. Estimation of prevalence rates and association between dependence and age of cannabis use initiation were performed. The conditional model was applied to investigate the mediation of depressive symptoms and alcohol consumption in the association of early cannabis use and dependence. Lifetime and last year cannabis use were 6.47% and 2.81%, respectively. Moderate and severe cannabis dependence were 0.74% and 0.18% in the population, and 26.47% and 6.38% among last year’s cannabis users. A Parallel Multiple Mediator Model revealed strong association between cannabis use initiation age and dependence, when depressive symptoms or alcohol consumption mediate this association. The proportion of cannabis users displaying dependence symptoms is elevated and it is associated with the age of cannabis use initiation. The results show the importance of primary prevention interventions, prioritizing the delay of cannabis and alcohol experimentation. Our findings can enrich the debate on drugs policies and legislation, reinforcing the need for stronger restrictions of adolescent drug access and ensuring its enforcement.

Prevalence of electronic nicotine delivery systems and waterpipe use in Brazil: where are we going?

To describe the prevalence of use of electronic nicotine delivery systems (ENDS) and waterpipe in Brazil, by population subgroups, and to evaluate the trend between 2013 and 2019. We used data from the 2019 National Health Survey to estimate the prevalence of lifetime and current use of ENDS and current use of waterpipes by socio-behavioral characteristics. Differences in prevalence over time were calculated using data from the III Brazilian Household Survey on Substance Use-2015 and the National Health Survey-2013. For 2019, the prevalence of current use of ENDS was estimated at 0.64% (∼1 million people), of which ∼70% were in the age group of 15-24 years old. The highest prevalence was observed in the Midwest region, but the Southeast region concentrates half of these users. Almost 90% are non-smokers, with high prevalence among those who also use waterpipe and abuse alcohol. There was an increase in ENDS use between 2015 and 2019, particularly among younger people. The prevalence of current waterpipe use in 2019 was estimated at 0.47% (∼800,000 individuals), of which ∼80% were 15-24 years old. There was an increase in the prevalence of current waterpipe use between 2013 and 2019, and among young people the increase was ∼300%. In Brazil, ENDS have been used mostly by young people, and by never smokers of manufactured cigarettes. The use of ENDS and waterpipe has been increasing even with the country's regulatory restrictions, which may compromise the successful history of the tobacco control policy.

Substance use, self-rated health and HIV status in Brazil

ABSTRACT We compared the prevalence of of non-injecting drug use (NIDU) and Self-Rated Health (SRH) among individuals self-reporting as HIV-positive (PLWHA), HIV-negative and unknown at the III Brazilian Household Survey on Substance Use. Overall, 16,273 individuals, 12–65 years old, were interviewed in 2015. Prevalence and Standard Error (SE) were estimated considering the complex sample design and weight calibration. Chi-square tests with Rao-Scott adjustment were used to test independence between NIDU, SRH and HIV status. PLWHA presented higher frequencies of 12-month use for most substances than those reporting to be HIV-negative: alcohol use prevalence was 49.5% (SE 12.8) vs. 43.1% (SE 0.7), p = 0.34; tobacco 45.3% (SE 12.7) vs. 15.3% (SE 0.4), p < 0.01; amphetamines 1.7% (SE 1.7) vs. 0.3% (SE 0.1), p = 0.51; cannabis 10.5%(SE 6.7) vs. 2.5%(0.2), p = 0.06; powder cocaine 3.6% (SE 3.0) vs. 0.9% (SE 0.1), p = 0.45; crack-cocaine 5.3% (SE 3.2) vs. 0.3% (SE 0.1), p < 0.01; inhalants 3.6% (SE 3.0) vs. 0.2% (SE 0), p = 0.03; ketamine 1.7%(SE 1.7) vs. 0.1% (SE 0), p = 0.23; and opioids 1.7% (SE 1.7) vs. 1.4% (SE 0.2), p = 0.93. PLWHA also reported worse SRH. Our results and the scarcity of integrated substance use and HIV treatments call for innovative, cost-effective approaches to tackle these public health challenges.

The Agricultural Wage Gap: Evidence from Brazilian Micro-data

A key feature of developing economies is that wages in agriculture are below those of other sectors. Using Brazilian household surveys and administrative panel data, I use information on workers who switch sectors and workers with multiple jobs to assess the role of worker composition in explaining this gap. The evidence is consistent with the presence of significant intersector sorting in Brazil. A calibrated sorting model can account for the wage gap level observed, as well as its decline, as the economy transitioned out of agriculture. (JEL J24, J31, J43, O13, Q10)

Chinese imports’ impacts on Brazil’s inter-industry wage premium

PurposeThe purpose of this paper is to investigate the effects of Chinese and non-Chinese import penetration on the inter-industry wage premium, and how such effects vary according to the unskilled-labor intensity of the industry and to the implementation of the Nova Matriz Economica policy in 2008.Design/methodology/approachThe paper empirically examines the effects of the Chinese and non-Chinese import penetration on the wage premium using a linear instrumental variables model and data from Brazilian household surveys and censuses.FindingsThe estimates show the Chinese import penetration positively affecting the wage premium in unskilled-labor intensive. And the implementation of the new macroeconomic policy strengthened this effect.Originality/valueTo the best of the author’s knowledge, this is the first paper to study the effects of Chinese and non-Chinese import penetration on the inter-industry wage premium.

Reproducibility on science: Challenges and advances in Brazilian alcohol surveys

BackgroundReproducibility in Science is challenging and may be hard to achieve in alcohol research. Previous general population surveys in Brazil have estimated the prevalence of alcohol dependence to be around 10%. We aim to estimate alcohol use and dependence using different methods and definitions. MethodsThe 3rd Brazilian Household Survey on Substance Use (BHSU-3) was a nationwide, probability sample survey that interviewed 16,273 individuals. DSM-IV-TR criteria were used to determine alcohol dependence. In the BHSU-2 (covering only Brazil’s 108 largest municipalities), alcohol dependence was defined as fulfilling 2/6 DSM-III criteria. Using the BHSU-3 data, alcohol use was estimated at: [1] the national level, [2] BHSU-2 municipalities, taking into consideration the sample design, and [3] BHSU-2 municipalities, ignoring the sample design. Alcohol dependence was calculated using: BHSU-3 and BHSU-2 definitions, two denominators ([A] population and [B] 12-month drinkers), and [1], [2], [3]. ResultsLifetime alcohol use ranged from 66.4% (95%CI:64.8–68.0 [1]) to 70.1% ([95%CI:69.1–71.0], [3]). The estimated population presenting with alcohol dependence ranged from N = 2.3 million (BHSU-3 definition, [1]) to N = 4.3 million (BHSU-2 definition, [1]). In the first case, the prevalence among the general population [A] and drinkers [B] was 1.5% (95%CI:1.2–1.8) and 3.5% (95%CI:2.8–4.2), respectively. In second case, prevalence was 2.8% (95%CI:2.4–3.3, [A]) and 6.6% (95%CI:5.6–7.6, [B]). ConclusionsPrevalence of alcohol dependence may vary as much as 4.3 times, analyzing the same dataset in different ways. Brazilian research on alcohol is funded by governmental research and policy-making agencies, providing subsidies for alcohol policy in the country. It is crucial that sufficient methodological information is provided in order to guarantee reproducibility and consistency over time.

Non-medical use of opioid analgesics in contemporary Brazil: Findings from the 2015 Brazilian National Household Survey on Substance Use

ABSTRACTPrior studies on substance use in Brazil have not focused on opioid misuse, previously thought to be nearly non-existent. This paper presents new findings on heroin and non-medical use of opioid analgesics. Data come from the 2015 Brazilian Household Survey on Substance Use (BHSU-3), a nationally representative survey estimating epidemiological parameters related to substance use by residents across Brazil. BHSU-3 used stratified multi-stage probability sampling across multiple geographic domains of interest, resulting in 16,273 interviews with household residents. Lifetime heroin use among Brazilians was 0.3 (95% C.I:0.2–0.4). Lifetime, past-year, and past-month non-medical use of opioid analgesics were respectively 2.9 (95%C.I.:2.3–3.4), 1.4 (95%C.I.:1.1–1.7) and 0.6 (95%C.I.:0.4–0.8). Past-year prevalence of non-medical opioid analgesics use was lower among males [Prevalence Ratio (PR): 0.54 (95% C.I.:0.36–0.78)], those aged 12–24 [0.56 (95% C.I.:0.34–0.92)], persons with monthly family incomes between R$1,501–3,000 [0.59 (95% C.I.:0.38–0.92)] or greater than R$3,000 [0.64 (95% C.I.:0.42–0.98)], and persons who were unemployed [0.65 (95% C.I.:0.46–0.92)]. Non-medical use of opioids in Brazil may be more prevalent than previously recognised. Proper measurement and evaluation of opioid misuse across Brazil and other Latin American countries is critical to understand and prevent opioid-related harms.

High-Crime Environment and Individual Portfolio Choice

We study the relationship between crime victimization and financial risk taking. Using data from two different Brazilian household surveys, we show that individuals who perceive violence in their neighborhoods are more likely to participate in the stock market. We also find that individuals have different economic reaction to different kinds of crime. Being a victim of violent property crimes has a negative effect on financial savings, while victims of nonviolent property crimes are more likely to have financial savings. The effect is stronger in low-crime states. Results are estimated controlling for macroeconomic and household characteristics. To the best of our knowledge this is the first paper addressing the relationship between crime victimization experiences and stock market participation.

The Agricultural Wage Gap: Evidence from Brazilian Micro-Data

A key feature of developing economies is that wages in agriculture are significantly below those of other sectors. Using Brazilian household surveys and administrative panel data, I use information on workers who switch sectors to decompose this gap. I find that most of the gap is explained by differences in worker composition. The evidence speaks against the existence of large short-term gains from reallocating workers out of agriculture and favors recently proposed Roy models of inter-sector sorting. A calibrated sorting model can account for the wage gap level observed and its decline as the economy transitioned out of agriculture.

IMPACTO DO PROGRAMA BOLSA FAMÍLIA SOBRE AS DECISÕES DE TRABALHO DAS CRIANÇAS: UMA ANÁLISE UTILIZANDO OS MICRODADOS DA PNAD

Em 2011, 4,33% das crianças entre 5 e 15 anos trabalhavam ou exerciam atividade para consumo próprio ou construção civil para uso próprio. O objetivo principal deste trabalho é examinar o impacto do Programa Bolsa Família sobre o trabalho infantil. O impacto é estimado através do método de propensity score matching. Também se estimam regressões utilizando, alternativamente, a renda proveniente de transferência social como variável explicativa. Os dados utilizados são os da Pesquisa Nacional por Amostra de Domicílios (PNAD) de 2011. O resultado mostra que o programa não tem impacto significativo sobre a probabilidade de a criança trabalhar e sobre as horas trabalhadas. Adicionalmente, observa-se que a renda proveniente de transferência social tem impacto negativo e significativo sobre a probabilidade de a criança trabalhar e sobre o número de horas trabalhadas. Assim, embora a participação no programa não tenha impacto sobre o trabalho infantil, a renda proveniente do programa atua no sentido de reduzir a probabilidade de a criança trabalhar e o número de horas trabalhadas.
