The aim of this paper is to assess the regional economic impact of the lockdown measures ordered by the national government to prevent the spread of COVID-19. Using an input-output model, we estimate the economic loss of extracting groups of formal and informal workers from different economic sectors. Results show monthly economic losses that represent between 0.5% and 6.1% of national GDP, depending on the scenario considered. Accommodation and food services, real estate, administrative services, construction and trade are the most affected sectors. Regionally,

El principal objetivo de este documento es evaluar el impacto económico regional y sectorial de las medidas de aislamiento preventivo ordenadas por el Gobierno Nacional para evitar la propagación del Covid-19. A través de un modelo insumo-producto, se estima la pérdida económica que resulta de extraer un grupo de empleados formales e informales de los distintos sectores y entidades territoriales del país. Los resultados señalan pérdidas económicas que varían entre $4,6 billones y $59 billones por mes de acuerdo con los escenarios de aislamiento considerados, cifras que representan entre 0,5% y 6,1% del PIB nacional. La rama económica de servicios aparece como la más afectada, donde se destacan las actividades de alojamiento y servicios de comida, servicios inmobiliarios, servicios administrativos, actividades profesionales y técnicas, construcción y comercio. Por su parte, los departamentos de Antioquia, Boyacá, San Andrés, Santander y Valle del Cauca aparecen como los más vulnerables a estas medidas.

Patent co-inventorship networks are important for knowledge acquisition and can influence the innovative performance of regions. However, collaborative networks play a different role depending on the regional characteristics. Thus, we analyze the relationship between the properties of technological collaboration networks and the inventive performance for core and peripheral regions. We also classified the regions using a typology created from their potential to access knowledge in the intra- and interregional networks. The collaborative networks were constructed by means of patent application data for Brazil in the period 2000–2011. The main results show that the external links in the co-inventorship networks are essential for regions that do not have autosufficiency to innovate. Therefore, the regions lagging behind can benefit from the diffusion of knowledge created in core regions by means the interregional collaborations with such regions.

AbstractMinas Gerais is the largest national milk producer. Milk activity is an important generator of direct and indirect jobs, and its evaluation can contribute to a better understanding of the regional growth process. Thus, this paper evaluated the spatial dimension of the milk production chain in Minas Gerais. The supply side and the intermediate and fi nal demand side treat these dimensions. In this way, we performed the mapping and the proposal of a typology of the municipalities in this productive chain through the construction of latent potential indicators. The main results allow tracing corridors, which can boost the economic development and the social insertion of the municipalities in this production chain. In addition, we identifi ed that the production growth is spatially concentrated. Therefore, from this analysis, we provide subsidies for the formulation of investment policies and microcredit policies for this activity.

O artigo faz uma análise da forma de inserção da carcinicultura do Nordeste, em particular dos Arranjos Produtivos Locais - APLs de cultivo de camarão do estado do Ceará, em cadeias globais de produção, bem como sua estrutura de governança. Isto porque os sistemas de cultivo destes crustáceos se concentram no Nordeste, sendo, na atualidade, o Ceará o maior produtor do Brasil na forma cultivado, expressando, ao longo de suas bacias hidrográficas, dois APLs bem característicos (litorais leste e oeste), que estiveram intensamente inseridos em mercado internacional por meio de cadeias globais de produção. O estudo teve por base um levantamento de dados secundários e entrevistas junto aos gestores e proprietários das empresas e outros agentes dos APLs. As principais evidências da pesquisa apontam que a inserção das empresas dos APLs ainda ocorre de forma dependente dos grandes compradores internacionais e os benefícios gerados, em grande parte, são apropriados fora da esfera produtiva, influenciando as capacitações produtivas e inovativas dos produtores locais. A estrutura de coordenação é verticalizada, demonstrado certo grau de assimetria nas relações de poder entre diferentes segmentos de agentes, sendo os principais estágios da cadeia de valor, em parte, controlados por agentes externos aos arranjos.

This paper analyses the impact of economic externalities on the local growth emphasizing the industrial, geographic, and temporal scope of agglomeration economies. Thus, we estimated a spatial dynamic panel model using GMM associated with the use of data at different levels of sectoral aggregation. Estimation takes into account the endogeneity of agglomeration economies. Our database consists of 558 Brazilian regions for 1995–2015. The main results suggest that while externalities act in a local dimension they also have a regional scale. These externalities are determined by their temporal trajectory. The effects of agglomeration economies on local growth are sensitive to the choice of sectoral aggregation. Local growth exhibits positive specialization effects and negative diversity effects. However, greater industrial diversity of neighbouring regions has a positive impact on local growth.
