How do countries specialize in agricultural production? A complex network analysis of the global agricultural product space

Using a complex-network perspective, this paper empirically explores the determinants of the process through which countries, given their capabilities, specialize in agricultural production. Using production data from the Food and Agriculture Organization (FAO) for the period 1993-2013, we characterize the agricultural production space as a time-sequence of bipartite networks, connecting countries to the agricultural products they produce. We then project this representation in the agricultural production spaces, linking countries or products according to their similarity in production profiles, and we identify properties and determinants underlying their evolution. We find that, despite the unprecedented pressure that food systems have been undergoing in recent years, the agricultural production space is a very dense network displaying well-defined and stable communities of countries and products. We also show that the observed country community structures are not only shaped by environmental conditions, but also by economic, socio-political, and technological factors. We conclude by discussing the implications of such findings on our understanding of the complex relationships involving production capabilities and specialization patterns.Fil: Campi, Mercedes Maria.

Changes in mobility and socioeconomic conditions during the COVID-19 outbreak

Since the outbreak of the 2019 novel coronavirus (COVID-19) pandemic, governments have been implementing containment measures aimed at mitigating the spread of the virus, including restrictions to human mobility. The ability to adapt to the pandemic and respond to containment measures can be bound by socioeconomic conditions, which are heterogeneous in large urban areas of low-income and middle-income countries. In this paper, we analyse mobility changes following the implementation of containment measures in Bogotá, Colombia. We characterise the mobility network before and during the pandemic and analyse its evolution and changes between January and July 2020. We observe a general reduction in mobility trends, but the overall connectivity between different areas of the city remains after the lockdown, reflecting the resilience of the mobility network. Then, we estimate a gravity model to assess the effect of socioeconomic conditions on mobility flows. We find that the responses to lockdown policies depend on the socioeconomic conditions of the population. Before the pandemic, the population with better socioeconomic conditions shows higher mobility flows. Since the lockdown, mobility presents a general decrease, but the population with worse socioeconomic conditions shows lower reductions in mobility flows. We conclude by deriving policy implications.Fil: Dueñas, Marco. Universidad de Bogota Jorge Tadeo Lozano; ColombiaFil: Campi, Mercedes Maria.

O fortalecimento dos direitos de propriedade intelectual estimula a inovação? Uma análise exploratória da dinâmica de patentes por setores industriais em Colômbia, 1980-2010

Los derechos de propiedad intelectual (DPI) y las patentes como mecanismos de impulso a la innovación han cobrado especial relevancia y debate en el contexto colombiano. Este artículo tiene como objetivo explorar el comportamiento de las patentes de residentes y no residentes para el período 1980-2010. En particular analiza cómo este comportamiento podría estar relacionado con el fortalecimiento de la legislación de propiedad intelectual y con el proceso de apertura económica y desindustrialización. La evidencia sugiere que el fortalecimiento de los DPI no ha incentivado la innovación local, sino que sólo ha impulsado las solicitudes de patentes de no residentes en unos pocos campos tecnológicos y por parte de unas pocas empresas multinacionales. En cambio, las empresas nacionales recurren al uso de mecanismos alternativos de propiedad intelectual como los acuerdos de confidencialidad y el secreto industrial para gestionar su conocimiento y apropiarse de las rentas asociadas a sus esfuerzos en actividades de innovación que se caracterizan por formas de innovar basadas en la imitación y adaptación de tecnologías extranjeras. Esta evidencia permite discutir la política de fortalecimiento de los DPI y el estímulo de las patentes de invención como mecanismo para incentivar la innovación en Colombia.This paper aims to explore the behavior of resident and non-resident patents during 1980 and 2010. In particular, it shows how this behavior could be related to the strengthening of intellectual property legislation and the process of economic liberalization and de-industrialization. The evidence suggests that Intellectual Property Rights –IPRs– have not incentivized local innovation but has only boosted patent applications from non-residents, owned by a few multinational companies in some technological fields. Instead, firms resort to the use of alternative intellectual property mechanisms such as confidentiality agreements and industrial secrecy. This mechanism allows them to manage their knowledge and appropriate the rents associated with their innovation efforts, which are characterized by the imitation and adaptation of foreign technologies. This evidence allows us to discuss the policy of strengthening IPRs and the incentives of invention patents as a mechanism to encourage innovation in Colombia.Este artigo tem como objetivo explorar o comportamento das patentes de residentes e não residentes durante 1980 e 2010.

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

Innovation and Intellectual Property Rights: The case of Soybean Seeds in Argentina and the United States

As a contribution to the open debate regarding the effect of intellectual property rights (IPRs) on innovation, this chapter postulates that the adoption of strong intellectual property rights (IPRs) is not a necessary condition to foster innovation in the plant breeding industry. The chapter studies the evolution of the soybean breeding industry in the US and Argentina and shows that regardless the level of intellectual property protection, if there is an attractive and profitable market, firms may search for different appropriability strategies rather than changing their innovative behavior. The chapter finds that the growth rates of new soybean varieties are similar in both countries and the adoption rate is faster in Argentina where the IPRs system is weaker.Fil: Campi, Mercedes Maria.

The Co-Evolution of Science and Law in Plant Breeding: Incentives to Innovate and Access to Biological Resources

This paper analyses the co-evolution of scientific progress and intellectual property protection in plant breeding and the debates generated in its design and implementation. It relates the institutional history to several problems related with incentives to innovate, appropriability of innovation rents, disclosure and cumulativeness, and diffusion and access to biological resources. We identify three main issues that were fiercely discussed along history: firstly, whether plant varieties and other biological resources could be considered as inventions or simple products of nature, secondly, how to provide incentives to plant breeders without preventing access to innovation and looking upon the contribution of farmers to obtain present improved varieties, and, thirdly, the social cost of generating monopolies in plant breeding and agriculture as food producers. These three issues have shaped the debates and remained controversial until our days. The analysis shows that legal and scientific factors evolved at different paces, resulting in different IPRs systems, and giving raise to several problems.Fil: Campi, Mercedes Maria.

The Effect of Intellectual Property Rights on Agricultural Productivity

This article explores how the strengthening of intellectual property (IP) protection affects agricultural productivity in a panel of countries for the period 1961–2011. Using an index of IP protection for plant varieties, we study the effect of stronger intellectual property rights (IPRs) on cereal yields and two different types of cereals: Open-pollinated (wheat) and hybrid (maize). We found that the strengthening of IPRs has a positive effect on productivity of cereals for high- and low-income countries. However, we found no significant effect for middle-income countries. In addition, we found that becoming a member of the Trade Related Aspects of Intellectual Property Rights negatively affects cereal yields. Finally, we found evidence of the existence of nonlinearities in the effect of IPRs on agricultural yields, which confirms a threshold effect of IPRs that also varies for countries of different income level. The findings support the hypothesis that country specificities are important in determining the effect of IPRs and imply that there is no unique system that fits all.Fil: Campi, Mercedes Maria.

Intellectual property rights and international trade of agricultural products

The signing of the agreement on Trade-Related Aspects on Intellectual Property Rights (TRIPS) had led to a process of global harmonization and tightening of intellectual property rights (IPRs) systems. As part of this process, theuse of IPRs in agriculture has been increasing in the last decades. This paper studies the effect of intellectual property rights on agricultural trade, for the post-TRIPS period (1995?2011), using a new yearly index of IPRs, for60 developed and developing countries. We study the effect of stronger IPRs on total trade, bilateral trade, and trade margins using different econometric techniques. We found that the strengthening of IPRs has been having a negative and uneven effect on agricultural trade at different levels of disaggregation. The gravity estimation showed that both the IPRs of the importer and the exporter have negative effects on total bilateral trade and that the probability of creating new bilateral trade links increases with the importer?s IPRs. Finally, we found that stronger IPRs have a negative effect on the intensive margin of trade and a positive impact on the extensive margin. Overall, the evidence shows that agricultural trade related to the developing world has been more negatively affected, which calls the attention to the idea that a common system can equally work for all countries.Fil: Campi, Mercedes Maria.

Intellectual property rights, trade agreements and international trade

The global process of strengthening and harmonization of intellectual property rights (IPRs) systems has been intensified in the last twenty five years by the signing of trade agreements (TAs) that include chapters with intellectual property (IP) provisions and other trade-related issues. This paper provides a first exploration of whether and how the signing of TAs with IP chapters influences bilateral trade flows for a balanced panel of 110 countries and the period 1995-2013. We address methodological issues related to the assessment of the effect of TAs on bilateral trade. We use matching econometrics to evaluate the treatment of TAs with and without IP chapters. In addition, we estimate the effects of TAs on bilateral trade in a more dynamic fashion using a panel data approach based on the gravity model. Also, we perform our analysis for trade in low- and high-IP intensive products. We found that both types of TAs increase bilateral trade but TAs with no IPRs chapters have a stronger positive effect on trade. However, if we include lags to consider that TAs with IP chapters might need a longer implementation time, the net expected increase on trade is similar for both types of TAs. We also found that the effects depend on the development level of countries and on the IP intensity of products. We found a clear positive effect for developed countries, but we do not observe important gains for developing countries in all sectors and to all destinations derived from TAs with IP chapters. This raises the question of whether trade gains can compensate the effort related with IP reforms.Fil: Campi, Mercedes Maria. Consejo Nacional de Investigaciones Científicas y Técnicas.

Volatility and economic growth in the twentieth century

This paper analyses the international distribution of GDP per capita growth rates and its dynamics during the twentieth century. We show that the century is characterized by a changing distribution of GDP per capita growth rates, which is reflected in different shapes and a persistent asymmetry at the regional level and for countries of different development levels. Interestingly, the well-known negative scaling relation between growth volatility and country size that characterizes the second half of the century is not observed before the 1950s, period dominated by severe global shocks. We discuss possible explanations to the disruption of the scaling relationship. We argue that in a turbulent context, the functioning and interdependence of economic components of countries of different size can be altered, also affecting the scaling relation between growth volatility and country size. Our results contribute with evidence of the underlying complexity of the growth process and its historical evolution.Fil: Campi, Mercedes Maria.
