The Economic Impact of Sanctions against Russia: Much ado about very little. CEPS Commentary, November 2015

The decision process leading to the imposition of sanctions against Russia in response to its annexation of Crimea and its subsequent military intervention in Eastern Ukraine has been very difficult for the EU, with some member states claiming that they have been particularly hard hit because exports to Russia are important to their economies. This commentary shows, however, that the economic cost in terms of lost exports, and thus potentially jobs, has in reality been negligible

Economic Incentives for Indirect TTIP Spillovers. CEPS Special Report No. 94/October 2014 [TTIP Series No. 2]

A deep, comprehensive and ambitious TTIP should not undermine or otherwise negatively affect the WTO and its signatories. Among other things, this means that trade diversion ought to be minimised and positive spillovers stimulated. The present CEPS Special Report provides some elementary quantification, which helps to understand the economic incentives for third countries to seek regulatory alignment with TTIP results, where relevant, and for which TTIP should be ‘open’. It focuses on ‘indirect’ spillovers and employs a rather aggregate economic approach. We find that, of three groups of countries that are important for trade with the EU and the US, the ‘closest’ neighbours (NAFTA, EEA, Switzerland and Turkey) exhibit powerful incentives to align so as to benefit from positive spillovers. This is less clear for two other groups. Of the (seven) ‘biggest traders’ (in manufactured goods, for which spillovers matter most), China turns out to have the greatest interest in alignment in selected sectors, followed by Israel, Japan and South Korea. Whereas the latter three either have or are negotiating FTAs with the US and the EU, precisely China has none and remains outside TPP as well. In terms of sectors, the chemical sector followed by electronic equipment are by far the most important, with agro-products and fish as a good third (SPS issues). However, in chemicals and electrical equipment, the TTIP negotiations so far, and recent US/EU regulatory cooperation, do not indicate an ambitious approach, which could reduce regulatory barriers to market access drastically

The Impact of TTIP: The underlying economic model and comparisons. CEPS Special Report No. 93/13 October 2014. [TTIP Series No. 1]

What are the economic and other impacts of the Transatlantic Trade and Investment Partnership? At the request of the European Parliament, CEPS has provided an appraisal of the TTIP Impact Assessment carried out by the European Commission, with special elaboration of the underlying economic model. The methodology applied by the Centre for Economic Policy Research (CEPR) for this economic modelling is analysed in depth, together with the assumptions used to make TTIP amenable to an economic appraisal. The research paper also compares the IA on TTIP with selected previous empirical economic assessments of EU trade agreements and with a set of alternative studies on TTIP itself. In reading our findings, two central caveats should be kept in mind that affect any analysis of the CGE model included in the European Commission’s Impact Assessment. First, TTIP is a rather unusual bilateral trade agreement; and second, TTIP is so wide-ranging that an alternative approach, such as the so-called ‘partial’ (equilibrium) approach – already a second-best solution – would be totally inappropriate to the case under examination

Tomorrow's silk road: Assessing an EU-China Free Trade Agreement.

Foreword. The Foreign Trade Association, which represents the European and international distribution and retail sector, commissioned this study in light of the importance of China as a sourcing country and its attractiveness as a rapidly growing consumer market. We believe that open borders and free trade can contribute to a broader choice and lower costs for consumers and create growth and employment in both Europe and China. This independent study aims to provide an in-depth contribution on the status of bilateral economic exchanges and persistent trade barriers that exist between the European Union and China. The second objective of the report is to encourage a frank and open dialogue, based on a scientific evaluation and without prejudice, on the possibility of a preferential trade agreement between the two sides. This study should be read by anyone who is interested in economic relations between the EU and China and in trade policy in general. The report provides many interesting findings and raises a number of surprising points. Overall, this study is one of the most significant contributions to the discourse on EU-China relations in recent years. We hope that this study will stimulate fresh thoughts on the benefits of closer future cooperation between two regions that have been interlinked since the times of antiquity and the first Silk Road

TTIP: Political and economic rationale and implications

The Transatlantic Trade and Investment Partnership will reduce tariffs and lower regulatory hurdles that currently impair trade between the EU and the US. However, TTIP has been controversial from the outset. Non-governmental organisations are concerned about lowered health and environmental standards, unions fear a further weakening of labour conditions, and economists debate whether or not there will actually be any noticeable impact on employment and GDP growth. This Forum, featuring contributions by the speakers at the 2015 Intereconomics conference, presents a balanced overview of both the prospective benefits as well as the possible drawbacks to the potentially monumental trade agreement

A chloroplast retrograde signal, 3’phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

Organelle-nuclear retrograde signaling regulates gene expression, but its roles in specialized cells and integration with hormonal signaling remain enigmatic. Here we show that the SAL1-PAP (3'-phosphoadenosine 5'- phosphate) retrograde pathway interacts with abscisic acid (ABA) signaling to regulate stomatal closure and seed germination in Arabidopsis. Genetically or exogenously manipulating PAP bypasses the canonical signaling components ABA Insensitive 1 (ABI1) and Open Stomata 1 (OST1); priming an alternative pathway that restores ABA-responsive gene expression, ROS bursts, ion channel function, stomatal closure and drought tolerance in ost1-2. PAP also inhibits wild type and abi1-1 seed germination by enhancing ABA sensitivity. PAP-XRN signaling interacts with ABA, ROS and Ca2+; up-regulating multiple ABA signaling components, including lowly-expressed Calcium Dependent Protein Kinases (CDPKs) capable of activating the anion channel SLAC1. Thus, PAP exhibits many secondary messenger attributes and exemplifies how retrograde signals can have broader roles in hormone signaling, allowing chloroplasts to fine-tune physiological responses.Wannarat Pornsiriwong, Gonzalo M Estavillo, Kai Xun Chan, Estee E Tee, Diep Ganguly, Peter A Crisp, Su Yin Phua, Chenchen Zhao, Jiaen Qiu, Jiyoung Park, Miing Tiem Yong, Nazia Nisar, Arun Kumar Yadav, Benjamin Schwessinger, John Rathjen, Christopher I Cazzonelli, Philippa B Wilson, Matthew Gilliham, Zhong-Hua Chen, Barry J Pogso

Augustan triumphal iconography and the Cantabrian Wars: Some remarks on round shields and spearheads depicted on monuments from the Iberian Peninsula and Italy

Depicted arms and armour became particularly widespread in the Augustan period, when the Prince’s veterans tended to emphasise their role in the consolidation of the Empire with the adoption of these war themes in their tombs. The comparison between some funerary reliefs from Italy, the so-called Lusitanian Warriors, and some monetary emissions from the Iberian Peninsula, together with a recent finding in the Forum of Augustus, allows for the hypothesis that the celebration of Augustan victories in this region could have significantly contributed to the repertoire of depicted weapons that celebrated the new Empire.<br><br>Las armas representadas en bajorelieve fueron particularmente generalizadas en la época de Augusto, cuando los veteranos del príncipe tendido a enfatizar su importancia en la consolidación del imperio con la adopción de estos temas de guerra en sus tumbas.

TaSnRK2.4, an SNF1-type serine/threonine protein kinase of wheat (Triticum aestivum L.), confers enhanced multistress tolerance in Arabidopsis

Osmotic stresses such as drought, salinity, and cold are major environmental factors that limit agricultural productivity worldwide. Protein phosphorylation/dephosphorylation are major signalling events induced by osmotic stress in higher plants. Sucrose non-fermenting 1-related protein kinase2 family members play essential roles in response to hyperosmotic stresses in Arabidopsis, rice, and maize. In this study, the function of TaSnRK2.4 in drought, salt, and freezing stresses in Arabidopsis was characterized. A translational fusion protein of TaSnRK2.4 with green fluorescent protein showed subcellular localization in the cell membrane, cytoplasm, and nucleus. To examine the role of TaSnRK2.4 under various environmental stresses, transgenic Arabidopsis plants overexpressing wheat TaSnRK2.4 under control of the cauliflower mosaic virus 35S promoter were generated. Overexpression of TaSnRK2.4 resulted in delayed seedling establishment, longer primary roots, and higher yield under normal growing conditions. Transgenic Arabidopsis overexpressing TaSnRK2.4 had enhanced tolerance to drought, salt, and freezing stresses, which were simultaneously supported by physiological results, including decreased rate of water loss, enhanced higher relative water content, strengthened cell membrane stability, improved photosynthesis potential, and significantly increased osmotic potential. The results show that TaSnRK2.4 is involved in the regulation of enhanced osmotic potential, growth, and development under both normal and stress conditions, and imply that TaSnRK2.4 is a multifunctional regulatory factor in Arabidopsis. Since the overexpression of TaSnRK2.4 can significantly strengthen tolerance to drought, salt, and freezing stresses and does not retard the growth of transgenic Arabidopsis plants under well-watered conditions, TaSnRK2.4 could be utilized in transgenic breeding to improve abiotic stresses in crops

ESCRT-I Component VPS23A Affects ABA Signaling by Recognizing ABA Receptors for Endosomal Degradation

[EN] Recent discovery of PYR/PYL/RCAR-type abscisic acid (ABA) receptors has become one of most significant advances in plant science in the past decade. In mammals, endosomal sorting acts as an important pathway to downregulate different types of receptors, but its role in plant hormone signaling is poorly understood. Here, we report that an ubiquitin E2-like protein, VPS23A, which is a key component of ESCRT-I, negatively regulates ABA signaling. VPS23A has epistatic relationship with PYR/PYL/RCAR-type ABA receptors and disruption of VPS23A enhanced the activity of key kinase OST1 in the ABA signaling pathway under ABA treatment. Moreover, VPS23A interacts with PYR1/PYLs and K63-linked diubiquitin, and PYL4 possesses K63-linked ubiquitinated modification in vivo. Further analysis revealed that VPS23A affects the subcellular localization of PYR1 and the stability of PYL4. Taken together, our results suggest that VPS23A affects PYR1/PYL4 via vacuole-mediated degradation, providing an advanced understanding of both the turnover of ABA receptors and ESCRTs in plant hormone signaling.This research was supported by grant 2016YFA0500500 from the National Basic Research Program of China and NSFC 31571441 from the National Science Foundation of China.Yu, F.; Lou, L.; Tian, M.; Li, Q.; Ding, Y.; Cao, X.; Wu, Y....
