This FAL Bulletin summarizes the main findings and proposals contained in the document “Políticas de logística y movilidad para el desarrollo sostenible y la integración regional”, recently published by the Natural Resources and Infrastructure Division (NRID), ECLAC. It contains a proposal for a paradigm shift in the formulation of national logistics and mobility policies, with common guidelines for Latin American and Caribbean countries.

Transforming growth factor-β and inflammation in vascular (type IV) Ehlers-Danlos syndrome.

BACKGROUND Vascular Ehlers-Danlos syndrome (VEDS) causes reduced life expectancy because of arterial dissections/rupture and hollow organ rupture. Although the causative gene, COL3A1, was identified >20 years ago, there has been limited progress in understanding the disease mechanisms or identifying treatments. METHODS AND RESULTS We studied inflammatory and transforming growth factor-β (TGF-β) signaling biomarkers in plasma and from dermal fibroblasts from patients with VEDS. Analyses were done in terms of clinical disease severity, genotype-phenotype correlations, and body composition and fat deposition alterations. VEDS subjects had increased circulating TGF-β1, TGF-β2, monocyte chemotactic protein-1, C-reactive protein, intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and leptin and decreased interleukin-8 versus controls. VEDS dermal fibroblasts secreted more TGF-β2, whereas downstream canonical/noncanonical TGF-β signaling was not different. Patients with COL3A1 exon skipping mutations had higher plasma intercellular adhesion molecule-1 and vascular cell adhesion molecule-1, and VEDS probands had abnormally high plasma C-reactive protein versus affected patients identified through family members before any disease manifestations. Patients with VEDS had higher mean platelet volumes, suggesting increased platelet turnover because of ongoing vascular damage, as well as increased regional truncal adiposity. CONCLUSIONS These findings suggest that VEDS is a systemic disease with a major inflammatory component. C-reactive protein is linked to disease state and may be a disease activity marker. No changes in downstream TGF-β signaling and increased platelet turnover suggest that chronic vascular damage may partially explain increased plasma TGF-β1. Finally, we found a novel role for dysregulated TGF-β2, as well as adipocyte dysfunction, as demonstrated through reduced interleukin-8 and elevated leptin in VEDS.

Economic Rights, Human Development Effort and Institutions

This paper focuses on the link between economic rights and institutions. Simple analysis of data is used to demonstrate countries' human development effort in advancing economics rights of the citizens. A country's human development effort is evaluated on the basis of the well-being of the poorest members of the society. An analysis of data reveals that there is a wide variation in countries' pro-poor stance. While it is accepted that positive rights are pro-poor, this paper argues that so too are negative economic rights and in fact the two are complements rather than substitutes. Classifying countries into human development income deficit and human development effort deficit, it is demonstrated that a large number of countries could achieve higher welfare levels for the poor if they improved on bother positive and negative economic rights. The paper attempts to explain variations in the observed commitment to economic rights by focusing on pro-poor institutions. The basic thesis advanced in the paper is that pro-poor policies are more likely to be implemented and sustained in those institutions where power is sufficiently diffused such that even the poor have leverage over policy outcomes. The paper focuses on how institutions impact on power diffusion and therefore the adoption of pro-poor growth and policies. The failure of countries to adopt pro-poor growth and policies is attributed to institutional failures manifested in concentration of power. The policy recommendations emanating from the analysis focus on institutional reforms to enhance power diffusion. These policies include enlarging the political space through democratization, strengthening institutions and capacity to fight corruption and improve transparency, and bringing the government closer to the people through appropriate design and implementation of decentralization schemes. Some recent examples of improvements in economic rights following power diffusion are provided.

Insulin-like growth factor binding protein 2 (IGFBP2) promotes glioma development and progression

Overexpression of insulin-like growth factor binding protein 2 (IGFBP2) is associated with progression and poor survival in many types of human cancer (such as prostate, ovarian, adrenocortical, breast, colorectal carcinomas, leukemia, and high-grade gliomas). We therefore hypothesize that IGFBP2 is a key regulator of tumor progression. We tested our hypothesis in gliomas using the somatic gene transfer RCAS-tva mouse model system, which permits the introduction of specific genes into specific, cell lineages, in this case glial cells (RCAS: Replication competent avian sarcomavirus, tv-a: avian RCAS virus receptor). Mice are transgenic and harbor the tv-a receptor under the control of a glial-specific promoter and study genes are cloned into the RCAS vector for post-natal intracranial delivery. For these experiments, the study genes were IGFBP2, platelet-derived growth factor B (PDGFB), K-Ras, Akt, and IIp45 (invasion inhibitory protein 45 kDa; known to bind and block IGFBP2 activity), which were delivered separately and in combination. Our results show that PDGFB signaling leads exclusively to the formation of low-grade (WHO grade II) oligodendrogliomas. PDGFB delivered in combination with IGFBP2 results in the formation of anaplastic oligodendrogliomas (WHO grade III), which are characterized by increased cellularity, vascular proliferation, small regions of necrosis, increased mitotic activity, and increased activation of the Akt pathway. IIp45 injected in combination with PDGFB and IGFBP2 ablates IGFBP2-induced tumor progression, which results in formation of low-grade oligodendrogliomas, and an overall reduction in tumor incidence. K-Ras expression was required to form astrocytomas with either IGFBP2 or Akt, indicating the activation of two separate pathways is necessary for gliomagenesis. In ex vivo experiments, blockade of Akt by an inhibitor led to decreased viability of cells co-expressing IGFBP2 versus PDGFB expression alone. This study provides definitive evidence, for the first time, that: (1) IGFBP2 plays a role in activation of the Akt pathway, (2) IGFBP2 collaborates with K-Ras or PDGFB in the development and progression of two major types of glioma, and (3) IGFBP2-induced tumor progression can be ablated by IIp45 or by specific inhibition of the Akt pathway. ^

Effectiveness and Challenges of Three Economic Corridors of the Greater Mekong Sub-region

Since the Greater Mekong Sub-region (GMS) program began in 1992, activities have expanded and flourished. The three economic corridors are composed of the East-West, North-South, and Southern; these are the most important parts of the flagship program. This article presents an evaluation of these economic corridors and their challenges in accordance with the regional distribution of population and income, population pyramids of member countries, and trade relations of member economies.

Agglomeration Economies in Japan: Technical Efficiency, Growth and Unemployment

This paper examines if the effects of agglomeration economies get manifested in technical efficiency and generate faster economic growth and higher (lower) levels of employment (unemployment). Using the prefecture level data for each of the two-digit groups of industries in Japan, the paper estimates region-specific technical efficiency index based on the stochastic frontier production function framework. The results of the factor analysis show that in most of the industry-groups (with a few exceptions) efficiency has a positive association with external scale variable(s). Though the relationship is not seen to be very strong, it would be equally erroneous to ignore the effect of agglomeration economies on efficiency. In the case of some of the light goods industries the agglomeration effect is relatively stronger. Further, economic growth varies positively with external scale variable(s) and unemployment rate tends to fall with respect to growth and concentration. All this tends to suggest that measures against industrial concentration may be counter-productive, particularly in the context of globalisation when countries are in dire need of raising productivity.

Intra-regional trade between China, Japan, and Korea : before and after the financial crisis

East Asian economies have been heavily dependent on the U.S. and EU markets, especially for the export of final goods. Therefore, once the financial crisis hit Western economies hard, the East Asian economies lost their major markets.Their production networks then worked to the region's disadvantage and stifled industrial development.This reflects the vulnerability of the East Asian economies which have adopted an export-led growth strategy. Such vulnerability needs to be addressed to prevent future economic crises, as well as to sustain economic growth. This paper examines the trade structure of the three countries-China, Japan, and Korea-before and after the Lehman Shock, and discusses how the three countries should cooperate in addressing imbalances in the trade structure.

Measuring global value chains and regional economic integration : an international input-output approach

Firms that are expanding their cross-border activities, such as vertical specialization trade, outsourcing, and fragmentation productions, have brought dramatic changes to the global economy during the last two decades. In an attempt to understand the evolution of the interaction among countries or country groups, many trade-statistics-based indicators have been developed. However, most of these statistics focus on showing the direct trade-specific-relationship among countries, rather than considering the roles that intercountry and interindustrial production networks play in a global economy. This paper uses the concepts of trade in value added as measured by the input–output tables of OECD and IDE-JETRO to provide alternative indicators that show the evolution of regional economic integration and global value chains for more than 50 economies. In addition, this paper provides thoughts on how to evaluate comparative advantages on the basis of value added using an international input–output model.

Factor decomposition of income inequality change : Japan's regional income disparity from 1955 to 1998

We propose a method for the decomposition of inequality changes based on panel data regression. The method is an efficient way to quantify the contributions of variables to changes of the Theil T index while satisfying the property of uniform addition. We illustrate the method using prefectural data from Japan for the period 1955 to 1998. Japan experienced a diminishing of regional income disparity during the years of high economic growth from 1955 to 1973. After estimating production functions using panel data for prefectures in Japan, we apply the new decomposition approach to identify each production factor’s contributions to the changes of per capita income inequality among prefectures. The decomposition results show that total factor productivity (residual) growth, population change (migration), and public capital stock growth contributed to the diminishing of per capita income disparity.

Spatial spillover effects in determining China's regional CO2 emission growth : 2007-2010

This paper proposes an alternative input-output based spatial-structural decomposition analysis to elucidate the role of domestic-regional heterogeneity and interregional spillover effects in determining China's regional CO2 emission growth. Our empirical results based on the 2007 and 2010 Chinese interregional input-output tables show that the changes in most regions' final demand scale, final expenditure structure and export scale give positive spatial spillover effects on other regions' CO2 emission growth, the changes in most regions' consumption and export preference help the reduction of other regions' CO2 emissions, the changes in production technology, and investment preference may give positive or negative impacts on other region's CO2 emission growth through domestic supply chains. For some regions, the aggregate spillover effect from other regions may be larger than the intra-regional effect in determining regional emission growth. All these facts can significantly help better and deeper understanding on the driving forces of China's regional CO2 emission growth, thus can enrich the policy implication concerning a narrow definition of "carbon leakage" through domestic-interregional trade, and relevant political consensus about the responsibility sharing between developed and developing regions inside China.

Patents and Economic Activity: The Need to Develop Prediction Methods for Patent Applications

Since the decade of the 1980’s the literature on economic development began paying attention to the cases of countries which were industrialized after the first industrial revolution. One of the most relevant aspects analyzed has been the role of technology as a factor which promotes or delays the process of catching up with technology leaders. As result of this interest, new and more adequate indicators were identified to provide a coherent explanation for technological activities and their relationship with economic efficiency. Although the earliest studies focused on analyzing the activities of research and development (R&D), recently the focus of analysis has shifted to another type of variables, more oriented towards the processes of innovation and the gathering of knowledge and capabilities, in which patents provide relevant information.

Sustainable Development and Collective Learning: Theory and a European Case Study. Bruges European Economic Policy (BEEP) Briefing 7/2004

Network governance of collective learning processes is an essential approach to sustainable development. The first section of the article briefly refers to recent theories about both market and government failures that express scepticism about the way framework conditions for market actors are set. For this reason, the development of networks for collective learning processes seems advantageous if new solutions are to be developed in policy areas concerned with long-term changes and a stepwise internalisation of externalities. With regard to corporate actors’ interests, the article shows recent insights from theories about the knowledge-based firm, where the creation of new knowledge is based on the absorption of societal views. This concept shifts the focus towards knowledge generation as an essential element in the evolution of sustainable markets. This involves at the same time the development of new policies. In this context innovation-inducing regulation is suggested and discussed. The evolution of the Swedish, German and Dutch wind turbine industries are analysed based on the approach of governance put forward in this article. We conclude that these coevolutionary mechanisms may take for granted some of the stabilising and orientating functions previously exercised by basic regulatory activities of the state. In this context, the main function of the governments is to facilitate learning processes that depart from the government functions suggested by welfare economics.
