Syndrome of inappropriate anti-diuretic hormone secretion (SIADH) and posterior cerebral artery ischaemic event : two uncommon complications following posterior fossa decompression

Neurosurgical procedures in cases of Type 1 Arnold Chiari Malformation (ACM) may result in a wide spectrum of complications. We report a case of a sixty-four year lady who underwent an elective posterior fossa decompression for Type 1 ACM. The procedure was complicated by syndrome of inappropriate anti-diuretic hormone secretion (SIADH) and an ischaemic cerebrovascular event affecting the posterior cerebral artery. The association of these complications with the procedure is rarely described in the literature. In spite of the poor prognosis associated with such complications, the patient made a relatively quick and uneventful recovery.peer-reviewe

The effects of alternative free trade agreements on Peru: Evidence from a global computable general equilibrium model

"By using a global computable general equilibrium model, this report analyzes the impact of various pending free trade agreements for Peru. In December 2007, a Peru–United States free trade agreement (FTA) was finally ratified by the U.S. Congress, replacing the Andean Trade Promotion and Drug Eradication Act, which awarded Peru and other Andean countries nonreciprocal preferential tariffs. A Peru–European Union (EU27) FTA is also being negotiated in the context of Peru's participation in the integration of the Andean Community (CAN). Finally, as of October 2008 Peru is concluding negotiations for a free trade agreement with China, its third major trading partner after the United States and the EU27. Although these agreements are expected to improve market access, their impact on the economic welfare of the beneficiary countries is dependent on the countries' structure of current tariffs and trade and the extent to which the new agreements result in trade diversion versus trade creation. The analysis shows that specific features of Peru's trade and tariff structures make the country a better candidate for a South-South FTA with China than for North-South FTAs with the United States or the EU27." from authors' abstractWTO, Free Trade Agreement, trade liberalization, CGE Modeling,

Two opportunities to deliver on the Doha Development pledge:

"In this brief, we evaluate the effects of a possible Doha agreement based on proposals currently on the table from the United States, the European Union, and the Group of Twenty (G20)....[The brief presents] two development-oriented alternatives...which demonstrate that more can be accomplished in the Doha Round if these two development-oriented and pro-trade measures are used." from TextAgricultural subsidies, tariffs, Doha Developmental Round of the World Trade Organization (WTO), Trade reform, Protectionism, trade policies, Trade barriers, exports, International trade, Market access, MIRAGE model,

Searching for an alternative to economic partnership agreements:

"On January 1, 2008, Economic Partnerships Agreements (EPAs), currently being negotiated between the European Union (EU) and nearly 80 African, Caribbean, and Pacific (ACP) countries, are expected to replace the Cotonou Agreement, which has governed trade relations between these countries since 2000. The Cotonou Agreement, implemented through a waiver from the World Trade Organization (WTO), expires on December 31, 2007. At the second EU-Africa summit, held in Lisbon on December 8–9, trade issues have been a major bone of contention, with several African heads of state denouncing the way the negotiation had been led by the European Commission. At the end of the summit, the Commission agreed to continue EPA negotiations in 2008." from textInternational agreements, Trade agreements,

Is SAFTA trade creating or trade diverting?: A computable general equilibrium assessment with a focus on Sri Lanka

The Agreement on South Asian Free Trade Area (SAFTA) entered its second phase of implementation in 2008. The creation of a free trade area is expected to affect its participants—Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka—very differently given their diversity in terms of size, income, and structure of trade and protection. Using the 2004 MAcMapHS6-v2 database on measures of applied protection at the HS6 level and MIRAGE, a computable general equilibrium global model, this study examines the effects of SAFTA on trade and net income in the region. The magnitude of the effects will depend on initial levels of protection in the region and whether the agreement is trade diverting or trade creating. An important component of the SAFTA agreement is the exemption of products (sensitive list) from the trade liberalization process. Because such exclusion can restrict significantly the benefits from the regional trade agreement, we simulate the effects of SAFTA with and without sensitive products. Our findings show that among South Asian countries, Sri Lanka gains the most from the agreement because it initially has relatively low tariffs and faces high tariffs in the region. Exempting sensitive products from the agreement limits gains from trade for the lower-middle-income members of SAFTA but may be welfare enhancing for the least developed economies.South Asian Free Trade Area (SAFTA), trade liberalization, Computable General Equilibrium (CGE) model, welfare, trade, applied protection, income, FTA, Markets, Globalization,

More or less ambition?: modeling the development impact of U.S.–EU agricultural proposals in the Doha Round

"What is at stake in the standoff between the United States and Europe over agriculture in the Doha Round of trade talks at the World Trade Organization (WTO)? What impact would an agreement based on greater or lesser levels of ambition have on developing countries, whose economies depend heavily on agriculture? Two years after the WTO talks broke down in Cancún, reform of the heavily protected and subsidized agricultural sectors of the United States and Europe remains a major impediment to progress. Using the MIRAGE computable general equilibrium model of the global economy, in this policy brief we compare different scenarios for the Doha agriculture negotiations, taking real numbers from the proposals currently on the table from the European Union (EU), the United States, and the G20 group of developing countries." from TextAgricultural subsidies, tariffs, Doha Developmental Round of the World Trade Organization (WTO), Trade reform, Protectionism, trade policies, Trade barriers, exports, International trade, General equilibrium model, Market access,

Genetically modified food and international trade: The case of India, Bangladesh, Indonesia, and the Philippines

"Genetically modified (GM) food crops have the potential to raise agricultural productivity in Asian countries, but they are also associated with the risk of market access losses in sensitive importing countries. We study the potential effects of introducing GM food crops in Bangladesh, India, Indonesia, and the Philippines in the presence of trade-related regulations of GM food in major importers. We focus on GM field crops (rice, wheat, maize, soybeans, and cotton) resistant to biotic and abiotic stresses, such as drought-resistant rice, and use a multi-country, multi-sector computable general equilibrium model. We build on previous international simulation models by improving the representation of the productivity shocks associated with GM crops, and by using an improved representation of the world market, accounting for the effects of GM food labeling policies in major importers and the possibility of segregation for non-GM products going toward sensitive importing countries. The results of our simulations first show that the gains associated with the adoption of GM food crops largely exceed any type of potential trade losses these countries may incur. Adopting GM crops also allows net importing countries to greatly reduce their imports. Overall, we find that GM rice is bound to be the most advantageous crop for the four countries. Second, we find that segregation of non-GM crops can help reduce any potential trade loss for GM adopters, such as India, that want to keep export opportunities in sensitive countries, even with a 5 percent segregation cost. Lastly, we find that the opportunity cost of segregation is much larger for sensitive importing countries than for countries adopting new GM crops, which suggests that sensitive importers will have the incentive to invest in separate non-GM marketing channels if exporting countries like India decide to adopt GM food crops." from Authors' AbstractGenetically modified food, International trade, Developing countries, Segregation,

Economic partnership agreements between the European Union and African, Caribbean, and Pacific Countries: What is at stake for Senegal

"In recent years the European Union has sought to transform its trading regime with the ACP countries by advocating reciprocal free trade agreements with them through Economic Partnership Agreements (EPAs). As a result, the EPA talks were launched in 2002 and were expected be completed by the end of 2007. Nevertheless, many African countries, including Senegal did not reach agreements with the European Union in 2007 amid rising concerns that such agreements do not represent the interests of developing countries. This policy shift from preferential trade to free trade would imply drastic changes for Senegal's economy, which currently enjoys relatively good access to European market (but also to the U.S. through the African Growth Opportunity Act) while applying a high domestic protection on all sources of imports. As a result, this type of reform would result in improved access to foreign markets only for the EU. Furthermore, the EPA implies a loss of tariff revenues from liberalization, which has been a key concern for ACP countries from the beginning of talks because they constitute a high level of public receipts there. Finally this kind of reform could lead to trade diversion in Senegal while creating not enough trade. Using the MIRAGE computable general equilibrium model the study examines the potential impact of Economic Partnership Agreements on ACP countries with a special focus on Senegal." from Author's AbstractEconomic partnership agreements, European Union, economic growth, Computable general equilibrium (CGE) modeling, trade, Markets, Globalization,
