Richer but Resented: What do Cash Transfers do to Social Relations?

Cash transfers are an increasingly important component of social protection systems in most countries. Usually, cash transfers are evaluated against their effects on poverty or human capital, with their impact on social relations within and between households relegated to discrete comments on ‘stigma’, ‘resentment’ and sharing, including reduction of remittances and other support. Using evidence from Oxford Policy Management's evaluations of cash transfer programmes in Malawi and Zimbabwe, we suggest reconceptualising cash transfers as ongoing processes of intervention in a complex system of social relations. Cash transfer interventions operate through and affect this system at each stage: awareness?raising, targeting, payment, case management and monitoring and evaluation. We conclude that the impact of cash transfers on social relations is large and often negative. We argue that this is intrinsically important for wellbeing, but can also have negative consequences for material aspects of wellbeing, such as livelihoods

Stabilization arising from PGEM : a review and further developments

The aim of this paper is twofold. First, we review the recent Petrov-Galerkin enriched method (PGEM) to stabilize numerical solutions of BVP's in primal and mixed forms. Then, we extend such enrichment technique to a mixed singularly perturbed problem, namely, the generalized Stokes problem, and focus on a stabilized finite element method arising in a natural way after performing static condensation. The resulting stabilized method is shown to lead to optimal convergences, and afterward, it is numerically validated

Social Protection and Climate Change

This overview is an introduction to the theme session on ‘Social protection and climate change’ in this IDS Bulletin . It first reviews the different dimensions of the relationship between social protection and climate change before presenting the articles of the session. The message that emerges from these analyses is twofold. On the one hand, there is a growing recognition that social protection needs to become ‘climate proofed’ if social protection interventions are to remain effective in the long term – in other words, social protection policymakers and practitioners cannot afford to ignore climate change any longer and need to integrate this new constraint into their planning and action plans. On the other hand, there is also growing evidence that social protection can play a critical role in reducing the immediate impact of climate change, and in the longer run, strengthen the resilience and adaptive capacity of people to climate change impacts

Governmentalizing Gramsci:Topologies of power and passive revolution in Cambodia’s garment production network

This article takes a fresh look at the multiple power relations between state, capital and labor in global production networks. Moving beyond debates about public vs. private governance, it brings together Antonio Gramsci’s concepts of hegemony and the integral state with Michel Foucault’s concepts of governmentality and the “dipositive” in order to analyze the power topologies that permeate global production networks. Using the Cambodian garment production network as example, we scrutinize the discourse of “decent work” and “ethical manufacturing,” exemplified by the Better Factories Cambodia program, and discuss the implications for labor agency, power and political contestation. The article concludes with reflections on “governmentalizing Gramsci,” thinking power topologically and the value of a cultural political economy in the analysis of global production networks

Open defecation and childhood stunting in India: an ecological analysis of new data from 112 districts.

Poor sanitation remains a major public health concern linked to several important health outcomes; emerging evidence indicates a link to childhood stunting. In India over half of the population defecates in the open; the prevalence of stunting remains very high. Recently published data on levels of stunting in 112 districts of India provide an opportunity to explore the relationship between levels of open defecation and stunting within this population. We conducted an ecological regression analysis to assess the association between the prevalence of open defecation and stunting after adjustment for potential confounding factors. Data from the 2011 HUNGaMA survey was used for the outcome of interest, stunting; data from the 2011 Indian Census for the same districts was used for the exposure of interest, open defecation. After adjustment for various potential confounding factors--including socio-economic status, maternal education and calorie availability--a 10 percent increase in open defecation was associated with a 0.7 percentage point increase in both stunting and severe stunting. Differences in open defecation can statistically account for 35 to 55 percent of the average difference in stunting between districts identified as low-performing and high-performing in the HUNGaMA data. In addition, using a Monte Carlo simulation, we explored the effect on statistical power of the common practice of dichotomizing continuous height data into binary stunting indicators. Our simulation showed that dichotomization of height sacrifices statistical power, suggesting that our estimate of the association between open defecation and stunting may be a lower bound. Whilst our analysis is ecological and therefore vulnerable to residual confounding, these findings use the most recently collected large-scale data from India to add to a growing body of suggestive evidence for an effect of poor sanitation on human growth. New intervention studies, currently underway, may shed more light on this important issue

A Toy Model for Testing Finite Element Methods to Simulate Extreme-Mass-Ratio Binary Systems

Extreme mass ratio binary systems, binaries involving stellar mass objects orbiting massive black holes, are considered to be a primary source of gravitational radiation to be detected by the space-based interferometer LISA. The numerical modelling of these binary systems is extremely challenging because the scales involved expand over several orders of magnitude. One needs to handle large wavelength scales comparable to the size of the massive black hole and, at the same time, to resolve the scales in the vicinity of the small companion where radiation reaction effects play a crucial role. Adaptive finite element methods, in which quantitative control of errors is achieved automatically by finite element mesh adaptivity based on posteriori error estimation, are a natural choice that has great potential for achieving the high level of adaptivity required in these simulations. To demonstrate this, we present the results of simulations of a toy model, consisting of a point-like source orbiting a black hole under the action of a scalar gravitational field.Comment: 29 pages, 37 figures.

Market selection of constant proportions investment strategies in continuous time

This paper studies the wealth dynamics of investors holding self-financing portfolios in a continuous-time model of a financial market. Asset prices are endogenously determined by market clearing. We derive results on the asymptotic dynamics of the wealth distribution and asset prices for constant proportions investment strategies. This study is the first step towards a theory of continuous-time asset pricing that combines concepts from mathematical finance and economics by drawing on evolutionary ideas

On computing upper and lower bounds on the outputs of linear elasticity problems approximated by the smoothed finite element method

Verification of the computation of local quantities of interest, e.g. the displacements at a point, the stresses in a local area and the stress intensity factors at crack tips, plays an important role in improving the structural design for safety. In this paper, the smoothed finite element method (SFEM) is used for finding upper and lower bounds on the local quantities of interest that are outputs of the displacement field for linear elasticity problems, based on bounds on strain energy in both the primal and dual problems. One important feature of SFEM is that it bounds the strain energy of the structure from above without needing the solutions of different subproblems that are based on elements or patches but only requires the direct finite element computation. Upper and lower bounds on two linear outputs and one quadratic output related with elasticity—the local reaction, the local displacement and the J-integral—are computed by the proposed method in two different examples. Some issues with SFEM that remain to be resolved are also discussed

Pricing behavior and the role of trade openness in the transmission of monetary shocks

© 2018 The empirical evidence on the role of trade openness in the monetary transmission is not conclusive: some studies find that it increases the sensitivity of output to monetary shocks, others find that it does not. Using a New Keynesian open economy model, I show that the role of trade openness in the transmission of monetary shocks can be reversed completely by the degree of exchange-rate pass-through into import prices. If the pass-through is complete, traded output increases more than nontraded output after a positive monetary shock, if the pass-through is zero, traded output increases less. Moreover, ignoring sectoral heterogeneity in price rigidity leads to an incorrect assessment of the role of trade openness in the transmission of monetary shocks
