The objective of this study is to measure the competitiveness of Brazilian wheat exporting states through the application of the performance matrix of Farias and Farias (2018), which is based on the Revealed Comparative Advantage (RCA) and the Relative Position (RPI) indexes. The main results obtained reveal that the country is not self-sufficient in wheat production, nor does it stand out in exports, needing to import large quantities of wheat to meet domestic demand. Among the producing states, São Paulo was the only one to present Revealed Comparative Advantages, and external potential. On the other hand, the Southern states (Paraná, Rio Grande do Sul, and Santa Catarina) do not have Revealed Comparative Advantages, but they are efficient in the commercialization of wheat to the international market, which indicates that these locations have internal potential to improve their competitiveness in this sector.
本研究的目的是通过应用 Farias 和 Farias(2018 年)的绩效矩阵来衡量巴西小麦出口国的竞争力,该矩阵基于显性比较优势(RCA)和相对地位(RPI)指数。得出的主要结果表明,圣保罗的小麦生产不能自给自足,出口也不突出,需要进口大量小麦来满足国内需求。在各生产州中,圣保罗是唯一一个具有显性比较优势和对外潜力的州。另一方面,南部各州(巴拉那州、南里奥格兰德州和圣卡塔琳娜州)不具备显性比较优势,但它们在向国际市场销售小麦方面效率很高,这表明这些地方具有提高该行业竞争力的内部潜力。

Previous literature suggests that trade contributes to knowledge and technology spillovers among trading partners. Using panel data and country-specific fixed effects, we show that the technology spillovers of a country is explained by the Economic Complexity from its major trading partners. We build an endogenous growth model for all OECD countries for the 1966–2016 period; we draw the residuals to measure the Total Factor Productivity of each country. Then, using spatial econometrics, we regress the Total Factor Productivity of each country on the Economic Complexity Index of its major trading partners. In addition, we run a Random Coefficient Model, to let this relationship vary randomly by country. We show that for 30 of the 36 countries, the TFP of a country positively depends on the ECI of its trading partners Finally, we run the endogenous growth model again, but now it includes the spatial lag term as an explanatory variable.
以往的文献表明,贸易有助于贸易伙伴之间的知识和技术外溢。利用面板数据和特定国家的固定效应,我们表明,一个国家的技术外溢可以用其主要贸易伙伴的经济复杂性来解释。我们为所有经合组织国家建立了 1966-2016 年期间的内生增长模型;我们利用残差来衡量每个国家的全要素生产率。然后,利用空间计量经济学,我们将每个国家的全要素生产率与其主要贸易伙伴的经济复杂度指数进行回归。此外,我们还运行了随机系数模型,让这种关系因国家而随机变化。我们发现,在 36 个国家中,有 30 个国家的全要素生产率与其贸易伙伴的经济复杂性指数呈正相关。

El presente artículo analiza el impacto de los fuertes desequilibrios fiscales que experimentaron las economías de los países de la Unión Europea en el periodo 2008-2018, principalmente debidos a la política fiscal implementada a raíz de la crisis financiera global. Con el objetivo de restaurar el equilibrio presupuestario, se desarrolló una respuesta coordinada desde el ámbito europeo inducida por la política de reglas fijada por el Pacto de Estabilidad y Crecimiento, condicionando la política fiscal a largo plazo. La principal estrategia consiste en situar al ciudadano europeo en el centro del estudio, analizando cómo evoluciona el empleo, a partir de los datos proporcionados por EUSILC ante los intentos por restaurar el equilibrio presupuestario. La novedad del presente artículo reside en el enfoque empleado. La mayoría de los trabajos previos se han basado en un enfoque macro tratando de cuantificar cómo el crecimiento económico y la productividad impactaban en la vida diaria de los europeos. Sin embargo, la investigación en este estudio persigue aislar y cuantificar los posibles efectos diferenciales en las condiciones de vida en función de las variables analizadas. En este sentido, se ha de resaltar que la relación entre los niveles de déficit excesivo y la evolución de los indicadores sociales, en este caso los correspondientes a los niveles de empleo, no ha sido estudiada con anterioridad.
本文分析了 2008-2018 年期间欧盟国家经济经历的严重财政失衡的影响,这主要是由于全球金融危机后实施的财政政策造成的。为了恢复预算平衡,在《稳定与增长公约》政策规则的诱导下,欧洲层面制定了协调的应对措施,对长期财政政策进行调节。主要策略包括将欧洲公民作为研究的中心,根据欧洲社会经济和地方发展研究所(EUSILC)提供的数据,分析在试图恢复预算平衡的情况下,就业是如何演变的。本文的新颖之处在于所采用的方法。以往的大部分研究都是基于宏观方法,试图量化经济增长和生产率对欧洲人日常生活的影响。然而,本研究试图根据所分析的变量,分离和量化对生活条件可能产生的不同影响。在这方面,应该指出的是,以前从未研究过赤字水平过高与社会指标(这里指的是与就业水平相关的指标)演变之间的关系。

El Affordable Care Act (ACA), conocido en español como la Ley de Asistencia Sanitaria Asequible, fue promulgado en 2010 en los Estados Unidos con el propósito de ampliar la cobertura de servicios de salud y atención médica. Esta ley aborda diversos desafíos relacionados con el acceso, la calidad y los costos en el sistema de atención médica estadounidense. El objetivo principal de este artículo es realizar un análisis transversal de la aplicación del ACA en diferentes áreas: política, social, sanitaria, económica y de gestión. Como metodología, se utilizó una revisión sistemática de la literatura científica. Para garantizar la transparencia y trazabilidad de esta revisión, se siguió el protocolo PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), que incluye las etapas de identificación de estudios relevantes, selección de dichos estudios, mapeo de datos, síntesis e informe de resultados. Entre los resultados más relevantes se destacan los siguientes aspectos: a nivel político, se requiere un mayor consenso para la implementación integral del ACA en los Estados Unidos; en términos económicos, el ACA ha popularizado fórmulas de copago y coseguro, así como sistemas de prestación de servicios basados en el valor; en elámbito social, se ha constatado que los altos costos compartidos dificultan el acceso a la atención médica y muchos ciudadanos están insuficientemente asegurados; en cuanto a la gestión, se destaca la necesidad de gestionar centralizadamente al paciente para aumentar la eficiencia; por último, a nivel médico, el ACA ha tenido un impacto positivo en el tratamiento yla prevención de diversas enfermedades. En conclusión, a pesar de los avances generados por el ACA, todavía no se ha logrado un equilibrio entre la coexistencia de los sistemas de salud privado y público que garantice una amplia cobertura sin barreras económicas u otras.
美国于 2010 年颁布了《可负担医疗法案》(ACA),英文全称为 Affordable Care Act,其目的是扩大医疗和医疗保障范围。该法解决了美国医疗保健系统在获取、质量和成本方面面临的一系列挑战。本文的主要目的是从政治、社会、卫生、经济和管理等不同领域对《美国医疗法案》的实施情况进行横向分析。在研究方法上,采用了对科学文献进行系统回顾的方法。为了保证综述的透明度和可追溯性,我们遵循了 PRISMA(系统综述和元分析首选报告项目)协议,其中包括相关研究的识别、选择、数据映射、综合和结果报告等阶段。在最相关的结果中,以下几个方面最为突出:在政治层面,美国需要达成更多共识才能全面实施《美国医疗保险法案》;在经济层面,《美国医疗保险法案》推广了共同支付和共同保险公式,以及基于价值的交付系统;在社会层面,《美国医疗保险法案》推广了共同支付和共同保险公式,以及基于价值的交付系统;在社会方面,高昂的费用分担阻碍了人们获得医疗保健服务,许多公民的保险额度不足;在管理方面,突出强调了集中管理病人以提高效率的必要性;最后,在医疗方面,《美国医疗保险法案》对各种疾病的治疗和预防产生了积极影响。总之,尽管《全民医保法案》取得了一些进步,但还没有实现私营和公共医疗系统共存的平衡,以保证在没有经济或其他障碍的情况下实现广泛的覆盖。

In this article, we proposed a novel convex penalized regression-type estimator, termed Olanrewaju-Olanrewaju penalized regression-type estimator, denoted by  Lo-oλγ(|θ|) for ultra and high-dimensional data consideration whenever the number of covariates (p) is strictly greater than the sample size(n⁡). The newly proposed penalized estimator was formulated via the unique combination of arctangent and hyperbolic functions. It was noted that the newly proposed estimator could efficiently work under the constraint pp. The proposed convex penalized regression-type estimator was formulated via three symmetric distributional noises of Gaussian, Laplace, and Normal Inverse Gaussian (NIG), considered being the three certified symmetric distributions that belong to the exponential family of distributions. The regularity axioms and oracle properties of the newly proposed penalized estimator were worked-out, as well as the parameter estimation for the penalized regression-type estimator for the three symmetric noises via canonical expressible form of Generalized Linear Models (GLMs) and first-order Karush-Kuhn-Tucker (KKT) condition.

在本文中,我们提出了一种新的凸惩罚回归型估计器,称为 Olanrewaju-Olanrewaju 惩罚回归型估计器,用 Lo-oλγ(|θ|) 表示,适用于协方差数量(p)严格大于样本量(n)的超高维数据考虑。新提出的惩罚性估计器是通过反正切函数和双曲函数的独特组合来制定的。新提出的凸惩罚回归型估计器是通过高斯、拉普拉斯和正态反高斯(NIG)这三种对称分布噪声提出的,它们被认为是属于指数分布族的三种经过认证的对称分布。通过广义线性模型(GLMs)的典型可表达形式和一阶卡鲁什-库恩-塔克(KKT)条件,研究了新提出的惩罚估计器的正则性公理和甲骨文特性,以及三种对称噪声的惩罚回归型估计器的参数估计。Lo-oλγ(|θ|) 回归型估计器对生成良好的对称观测数据进行了模拟研究。在三种对称分布噪声的保护下,用 Lo-oλγ(|θ|) 回归型估计器拟合了 p

The advertising world has been always concerned looking for the relationship between TV advertising spending and the sales amount of advertised products, particularly mass consumer goods (edibles) and automobiles. The measures was the relationship between advertising pressure in terms of GRP's and notoriety be spontaneous or suggested recall, which was supposed to be translated into sales later, but the consumer needed to have the product available on the shelf. Retain sales are controlled at brand/item level but ads are usually linked to brands. Sinergetics through a model used to explain the Formation of Public Opinion offers a platform to link group attractiveness by TV investment with product sales. We checked it for a narrow market as the colas reversing the reasoning. If the system forecast two groups of opinion that we assimilate to sales how much of the TV advertising expenditure can be correlated. More than 70%.
广告界一直在关注电视广告支出与广告产品(尤其是大众消费品(食品)和汽车)销售量之间的关系。衡量标准是以 GRP 为单位的广告压力与自发或建议召回的知名度之间的关系,这本应在日后转化为销售额,但消费者需要在货架上买到产品。留存销售是在品牌/单品层面上控制的,但广告通常与品牌挂钩。Sinergetics 通过一个用于解释 "舆论形成 "的模型,提供了一个将电视投资对群体的吸引力与产品销售联系起来的平台。我们对可乐这一狭窄市场进行了反向推理。如果系统预测两组舆论,我们将其同化为销售额,那么有多少电视广告支出可以与之相关联。超过 70%。
