Predicting the poverty impacts of trade reform

An important area of research in recent years involves assessing the microeconomic implications of macro-level policies-particularly those related to international trade. While a wide range of research methodologies are available for assessing the microeconomic incidence of micro-policies, as well as for assessing the effect of macro-level policies on markets and broad groups of households, there is a gap when it comes to eliciting the disaggregated household and firm level effects of trade policies. Recent research addresses this knowledge gap and the present survey offers an overview of this literature. The preponderance of the evidence from the studies encompassed by this survey points to the dominance of earnings-side effects over consumption-side effects of trade reform. This is problematic, since household surveys are notable for their underreporting of income. From the perspective of the poor, it is the market for unskilled labor that is most important. The poverty effects of trade policy often hinge crucially on how well the increased demand for labor in one part of the economy is transmitted to the rest of the economy by way of increased wages, increased employment, or both. Further econometric research aimed at discriminating between competing factor mobility hypotheses is urgently needed.Health Economics&Finance,Environmental Economics&Policies,Economic Theory&Research,Labor Policies,Payment Systems&Infrastructure,Environmental Economics&Policies,Economic Theory&Research,Poverty Assessment,Achieving Shared Growth,Health Economics&Finance

Stereo electro-optical tracker study for the measurement of model deformations at the National Transonic Facility

The effects of model vibration, camera and window nonlinearities, and aerodynamic disturbances in the optical path on the measurement of target position is examined. Window distortion, temperature and pressure changes, laminar and turbulent boundary layers, shock waves, target intensity and, target vibration are also studied. A general computer program was developed to trace optical rays through these disturbances. The use of a charge injection device camera as an alternative to the image dissector camera was examined

INCORPORATING COMMODITY STOCKHOLDING BEHAVIOR INTO A SHORT-RUN GENERAL EQUILIBRIUM MODEL OF THE GLOBAL ECONOMY

This paper incorporates commodity stockholding into a short run, stochastic global general equilibrium model. A mix of econometric and calibration techniques are used to reconcile model outcomes with historical stockholding and price behavior. The resulting framework is useful for analyzing policies in the short run or presence of production variability.Agribusiness,

TRADE POLICY, FOOD PRICE VARIABILITY, AND THE VULNERABILITY OF LOW-INCOME HOUSEHOLDS

We utilize a global trade model to generate distributions of commodity and factor prices based on observed uncertainty in rice production. This is done for three trade policy regimes. We then assess their impact on domestic price variability and the likelihood of marginal households falling into poverty in four countries.Food Security and Poverty, International Relations/Trade,

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,

Magnetization structure of a Bloch point singularity

Switching of magnetic vortex cores involves a topological transition characterized by the presence of a magnetization singularity, a point where the magnetization vanishes (Bloch point). We analytically derive the shape of the Bloch point that is an extremum of the free energy with exchange, dipole and the Landau terms for the determination of the local value of the magnetization modulus.Comment: 4 pages, 2 figure

Inapproximability of the Standard Pebble Game and Hard to Pebble Graphs

Pebble games are single-player games on DAGs involving placing and moving pebbles on nodes of the graph according to a certain set of rules. The goal is to pebble a set of target nodes using a minimum number of pebbles. In this paper, we present a possibly simpler proof of the result in [CLNV15] and strengthen the result to show that it is PSPACE-hard to determine the minimum number of pebbles to an additive $n^{1/3-\epsilon}$ term for all $\epsilon > 0$, which improves upon the currently known additive constant hardness of approximation [CLNV15] in the standard pebble game. We also introduce a family of explicit, constant indegree graphs with $n$ nodes where there exists a graph in the family such that using constant $k$ pebbles requires $\Omega(n^k)$ moves to pebble in both the standard and black-white pebble games. This independently answers an open question summarized in [Nor15] of whether a family of DAGs exists that meets the upper bound of $O(n^k)$ moves using constant $k$ pebbles with a different construction than that presented in [AdRNV17].Comment: Preliminary version in WADS 201
