Potential Implications of a Special Safeguard Mechanism in the WTO: the Case of Wheat

The Special Safeguard Mechanism (SSM) was a key issue in the July 2008 failure to reach agreement in the WTO negotiations under the Doha Development Agenda. It includes both price (P-SSM) and quantity-triggered measures (Q-SSM). This paper uses a stochastic simulation model of the world wheat market to investigate the effects of policy makers implementing policies based on the SSM rules. As expected, implementation of the Q-SSM is found to reduce imports, raise domestic prices, and boost mean domestic production in the SSM regions. However, rather than insulating countries that use it from price volatility, it would actually increase domestic price volatility in developing countries, largely by restricting imports when domestic output is low and prices high. We estimate that implementation of the Q-SSM would shrink average wheat imports by nearly 50% in some regions, with world wheat trade falling by 4.7%. The P-SSM is discriminatory against low price, developing country exporters and tends to contribute to additional producer price instability.Safeguard, SSM, WTO, volatility, wheat, food security, Agricultural and Food Policy, International Development, Q1, Q17, Q18,

Growth, globalization, and gains from the Uruguay Round

Emphasizing the importance of evaluating the Uruguay Round in the context of a changing world economy, the authors base their projections on a model that incorporates certain economic shifts: 1) that the center of economic gravity will shift toward the South and toward Asia (a shift that is already under way and shows no signs of abating), and 2) that the pattern of comparative advantage will continue to change, with the East Asian economies gaining comparative advantage in the production of physical and human-capital-intensive products. The authors argue that these changes in the global economy significantly affect their analysis of the Uruguay round reforms, for two reasons. First, with the global distribution of trade and production shifting toward Asia, the deeper Uruguay Round cuts inthat region become more important, giving rise to a 17 percent increase in the proportionate welfare gain after implementation of tariff cuts. Second, without the Round, almost all of the bilateral quotas associated with the Multifibre Arrangement (MFA) would have become more binding and the resulting distortion would have been significantly greater. In this analysis, the global gain from MFA reform is 60 percent greater than it would have been without taking into account the effects of growth. Of course, procedures for implementation of the MFA reforms are more complex than they have conveyed for purposes of analysis. In practice, one must also consider the impact of accel quota growth under the Agreement on Textiles and Clothing. But even when the Agreement on Textiles and Clothing is implemented over the period for which projections were made, quota rents rise for many bilateral flows. This is a consequence both of shifts in comparative advantage toward the supplying countries and of simultaneous cuts in tariffs on textiles and clothing. The projections approach used here may be viewed as a logical extension of the growing econometric literature seeking to explain the determinants of economic growth through regression analysis. By offering a bridge between econometric evidence and computable general equilibrium modeling, the authors hope to combine the two approaches to help shed light on the interaction between trade reform and economic growth.Payment Systems&Infrastructure,Economic Theory&Research,Environmental Economics&Policies,Export Competitiveness,Globalization and Financial Integration,Environmental Economics&Policies,Trade and Regional Integration,Achieving Shared Growth,Economic Theory&Research,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT

Asia-Pacific food markets and trade in 2005: a global, economy-wide perspective

Rapid industrialization in East Asia, particularly China, is raising questions about who will feed the region in the next century and how Asia will be able to pay for its food imports. The paper ®rst reviews existing food sector projections and then takes an economy-wide perspective using projections to 2005, based on the global CGE model known as GTAP. After showing the impact of implementing the Uruguay Round, the paper explores several alternative scenarios. A slowdown in farm productivity growth is shown to be costly to the world economy, as is slower economic growth in China. Failure to honour Uruguay Round obligations to open textile and clothing markets in OECD countries would reduce East Asia's industrialization and thereby slow its net imports of food. On the other hand, the trade reform that is likely to accompany China's (and hence Taiwan's) member- ship of the World Trade Organization (WTO) adds 30 per cent to estimated global gains from the Uruguay Round. Their WTO accession is projected to boost exports of manufactures and strengthen food import demand by not only China but also its densely populated neighbours with whom it trades intensively.International Relations/Trade,

Empowering Users to Create Augmented Reality-Based Solutions – Deriving Design Principles for No-Code AR Authoring Tools

Grounded on an experimental study with 18 participants, we derive 15 design principles for no-code AR authoring tools in an organizational setting. The study consists of two distinct treatments that aim to augment lightweight processes with AR. The outcomes are two interactive tutorials utilizing AR instructions. Following the no-code approach, the participants were empowered to create relevant AR content using a reduced interface and no need for advanced configurations or coding. The study thus combines two research streams with the aim of better understanding mechanisms for AR use in a professional context. As prior work has shown, despite the potential benefits, the adoption of AR authoring tools is limited because ramping up AR to productive use is heavily dependent on consulting and custom software solutions. Our novel approach bears the potential to broaden application domains and empower professionals to apply AR

Zwischen Zentren und Peripherien.: Vorstellungen von Westeuropa in Expertendiskursen der Nachkriegszeit

Since the so-called “spatial turn”, historians have been intensively dealing with concepts of space and macro-regions. While Eastern Europe has received considerable attention, fewer studies have examined Western Europe and its heterogeneities during the Cold War era, especially beyond the examples of Great Britain, France, or Germany. The current issue analyses the internal differences in Western Europe from the 1940s until the end of the 1970s. It explores in particular the contrast between the geopolitical discourse of a homogeneous “Western bloc” and competing concepts that stressed the internal differences between the countries and regions considered to belong to the geopolitical “West”, such as the idea of industrialized “Northern” and agrarian “Southern” countries and regions. By focusing on the role of experts in national and transnational spheres, their discourses, as well as approaches to economic, political, and cultural differences, it demonstrates, via implicit and explicit concepts of a “North” and a “South”, how the idea of the “West” was negotiated and discussed

Conceptualizing Interactions of Augmented Reality Solutions

The rapid evolution of augmented reality has resulted in an ever-increasing number of applications in a wide range of industries and services. Despite this progress, there is still a lack of conceptual understanding of AR interactions and the entire solution space. To bridge this gap, we conceptualize AR solution interactions and provide a comprehensive taxonomy. To represent the state-of-the-art, we build upon an extensive literature review. The resulting taxonomy consists of seven dimensions that encompass 29 characteristics. We contribute to the understanding of AR interactions and, as a result, the applicability of AR solutions in businesses by developing the taxonomy. Likewise, the taxonomy can guide the design of AR solutions as it convincingly describes the solution space

SOC in a population model with global control

We study a plant population model introduced recently by J. Wallinga [OIKOS {\bf 74}, 377 (1995)]. It is similar to the contact process (`simple epidemic', `directed percolation'), but instead of using an infection or recovery rate as control parameter, the population size is controlled directly and globally by removing excess plants. We show that the model is very closely related to directed percolation (DP). Anomalous scaling laws appear in the limit of large populations, small densities, and long times. These laws, associated critical exponents, and even some non-universal parameters, can be related to those of DP. As in invasion percolation and in other models where the r\^oles of control and order parameters are interchanged, the critical value $p_c$ of the wetting probability $p$ is obtained in the scaling limit as singular point in the distribution of infection rates. We show that a mean field type approximation leads to a model studied by Y.C. Zhang et al. [J. Stat. Phys. {\bf 58}, 849 (1990)]. Finally, we verify the claim of Wallinga that family extinction in a marginally surviving population is governed by DP scaling laws, and speculate on applications to human mitochondrial DNA.Comment: 19 pages, with 10 ps-figured include
