Título: Efetividade de uma ação governamental voltada à segurança alimentar no Estado da Paraíba: o caso do Programa Tá na Mesa Autor(es): Fernandes, Elza Adrianis Gonçalves Montenegro Orientador: Almeida, Aléssio Tony Cavalcanti de Abstract: This study aims to analyze the effectiveness of the government action called Tá na Mesa, instituted by the Government of the State of Paraíba during the Covid-19 pandemic, on the indicator of low birth weight among live births to mothers residing in the benefited locations. Given the varying scale of program implementation (from 34 to 149 municipalities throughout the analysis period), the methodology employed is a difference-in-differences model with multiple time periods, utilizing a municipal-level panel dataset with 1,338 observations from June 2019 to August 2024. The results show that the Tá na Mesa Program did not have a statistically significant impact on the prevalence of low birth weight in the municipalities benefited by the intervention. These findings suggest that the effectiveness of the policy may be related to factors that deserve further investigation and adjustments in its design and implementation, especially to strengthen actions to combat food insecurity in the State of Paraíba.

Título: Impacto da presença de crianças em creches no domicílio sobre a condição do jovem nem-nem: uma análise para o Brasil no ano de 2022 Autor(es): Lima, Anderson Henrique Fabião Cavalcanti Orientador: Silva, Magno Vamberto Batista da Abstract: This study investigates the impact of children aged 0 to 5 attending daycare or preschool on the condition of young individuals aged 15 to 29 who are neither in education nor employment (NEET) and reside in the same household. Using data from the second quarter of 2022 from the Continuous National Household Sample Survey (PNADc/IBGE), the Propensity Score Matching method was applied, incorporating Mahalanobis distance and entropy balancing, under a binary discrete choice model with the logit hypothesis. These procedures ensured balance between the treated group (households with enrolled children) and the control group (households without enrolled children), minimizing selection bias. The results indicate that the presence of children enrolled in early childhood education reduces the probability of NEET youth in the same household by an average of 38.05%. In 2022, 22.3% of Brazilian youth were NEET, totaling 10.9 million individuals, 63.4% of whom were women, often responsible for caregiving tasks that limit their educational and professional opportunities. The analysis highlights that access to early childhood education not only promotes children’s social inclusion but also contributes to keeping young individuals in education or the labor market by freeing caregivers, especially mothers, to invest in their careers and education. The findings underscore that early childhood education generates long-term family benefits by preparing children for academic and professional success and positively influencing young people’s economic engagement. Expanding access to early childhood education is emphasized as a critical public policy strategy to reduce NEET rates, fostering social inclusion and economic development in Brazil.

Título: Efeitos da privatização da Liquigás Distribuidora sob três óticas: consumidor, firma e mercado Autor(es): Furuyama, Pedro Henrique Maciel Orientador: Almeida, Aléssio Tony Cavalcanti de Abstract: This study aims to evaluate the impact of the privatization of Liquigás Distribuidora S.A., a Liquefied Petroleum Gas (LPG) distribution company, from three perspectives: consumer, firm, and market. From the consumer perspective, the variable of interest to be evaluated is the price paid by consumers for purchasing a 13-kg LPG cylinder from Liquigás. From the firm perspective, the analysis focuses on the price paid by Liquigás-branded resellers when purchasing 13-kg LPG cylinders. Additionally, the impact of the privatization on the markup of these branded resellers is assessed. From the market perspective, the variable of interest is the volume of LPG sold by the distributor in containers of up to 13 kg. To measure the impact, the Synthetic Control Method was applied in conjunction with data provided by the National Agency for Petroleum, Natural Gas, and Biofuels (ANP), the Brazilian Federal Revenue Service, and the Annual Social Information Report (RAIS) at the firm level, covering the period from January 2019 to December 2023. Overall, the results regarding the impact of the privatization of Liquigás Distribuidora S.A. were either not significant or of low magnitude. For instance, the estimated impact on the price paid by branded resellers was an increase of approximately BRL 1 per 13-kg LPG cylinder. The exception was the results related to the variable "quantity sold,"which indicated a significant effect resulting from the policy. These findings provide evidence regarding the effectiveness of Petrobras’ divestment policy and Brazil’s antitrust policy. After the privatization process, no significant deterioration in consumer welfare, reseller supply conditions, or the competitive environment of the LPG sector was observed.

Título: Investimentos Públicos em infraestrutura no Brasil: uma análise a partir de um modelo DSGE Autor(es): Alves, Karlos Rafael Soares Orientador: Frascarolli, Bruno Ferreira Abstract: The objective of this study is to analyze the macroeconomic impacts of delays inherent to the implementation of public investments in Brazil. For this purpose, a Dynamic Stochastic General Equilibrium (DSGE) model is used, with simulations conducted to evaluate the impacts of expansionary shocks in public consumption and investment. The research considers the effects of delays, such as time to spend and time to build, on the effectiveness of fiscal policies. The model is based on the New-Keynesian theory, inspired by the framework proposed by Ramey (2020), incorporating relevant specifications for the Brazilian economy, such as habit formation in consumption, liquidity constraints, investment adjustment costs, and variable capital utilization. Impulse Response Functions (IRFs) and fiscal multipliers are employed as the main metrics to measure short- and long- term effects. The results indicate that delays in public investment execution significantly reduce the fiscal stimulus effects on output, with smaller or even negative impacts in the short term. Public consumption demonstrates a greater capacity to generate short-term stimulus compared to public investment under delay scenarios. Editor: Universidade Federal da Paraíba Tipo: Dissertação
