Fuel-efficient stoves for Darfur: The social construction of subsistence marketplaces in post-conflict settings

This paper explores the development of market roles and transactions in fuel-efficient stoves in Darfur from 1997 to 2008 as a grounded example of how subsistence markets are socially constructed in post-conflict settings. Using a combination of archival texts, interviews, and real-time discourses by protagonists, this study explains the who, what, why and how of emergent marketplaces by showing how development interventions come to imbue market participants and transactions with socially (re)constructed meanings. The fitful emergence of subsistence marketplaces for fuel-efficient in Darfur is punctuated by development interventions which at times under- or misrepresent market participants and by successes and failures in bringing together trainers, producers, sellers, consumers and users of fuel-efficient stoves. Subsidies and handouts delay and distort the emergence of grassroots demand, choices, and prices; a plurality of competing development interventions re-shape the supply. By the end of 2008, the subsistence market for fuel-efficient stoves catches momentum, engaging over 52% of the Darfuri communities in market transactions for the product. As market participants gain voice and influence they reshape the market to favour mud stoves over metal stoves. Reports by several development organizations suggest that among fuel-efficient stove users, 90% use mud models, and 49% of women who own both mud and metal stoves prefer mud stoves.     

Screening and brief interventions for substance use in emergency departments in the Western Cape province of South Africa: views of health care professionals

As part of the formative phase of screening and brief interventions (SBIs) for substance use amongst patients presenting for emergency services in South Africa, the present study explored health care providers’ attitudes and perceptions towards SBI. Twenty-four health care providers working in two 24-hour emergency departments (EDs) were interviewed using an open-ended semi-structured interview schedule designed to identify factors that may hinder or promote the implementation of SBI for substance use in these settings. All respondents felt that screening patients for substance use in EDs is possible; however, they emphasised the need for an additional staff member dedicated to these activities. Secondly, they felt this dedicated individual should meet certain educational criteria and be from a specific socio-demographic background in order to increase the likelihood of intervention uptake. Thirdly, a number of patient- and clinic-level barriers were revealed that could potentially hinder the successful implementation of SBIs in EDs.     

The Theory of Exchange Rate Target Zones

The theory of exchange rate target zones focuses on the role of exchange rate expectations in determining exchange rate behaviour and interest rate differentials in currency bands. This paper analyses earlier models of the target zone research programme as well as more recent developments including endogenous realignment expectations, price rigidities and alternative monetary feedback rules by means of a unified approach. Target zones may be the cause of stabilizing or destabilizing exchange rate expectations, the determinants of which crucially depend on the within-band central bank policy as well as the credibility of the central banks' commitment to defend the target zone. The paper closes with a discussion of the relative merits of implementing a target zone and some suggestions for further research.     

Government interventions and the size of the informal economy. The case of Iran (1971–2007)

Literature on the informal economy can mainly be divided into two different contrasting theories. According to the dual labor market theory (DLM), which considers the informal economy as a spare sector providing jobs for formally unemployed resources, unpleasant economic situations force people to act informally. Legalists, on the other hand, blame government interventions such as minimum wages or price control policies for pushing rent-seeking firms toward the shadows. This study using an Error-correction Multi-Indicators Multi-Causes (EMIMIC) model, a systematic method consisting of structural and measurement equations, shows that these two theories are complementary rather than substitutes for one another. While long-term trends are explained by legalists, DLM theory is also suitable for explaining short term changes. Iran’s economy in the period 1971–2007, which was characterized by government interventions, is chosen for this purpose. These interventions are measured by Principal Component Analysis. Finally, an index of the size of Iran’s informal economy is also reported.     

How much would low- and middle-income countries benefit from addressing the key risk factors of road traffic injuries?

Abstract

Despite strong advocacy, the UN Decade of Action for Road Safety (2011–2020) is ending with most low- and middle-income countries (LMICs) no closer to the Sustainable Development Goals target of reducing traffic mortality by half. In contrast, most high-income countries (HICs) have seen large benefits in recent decades from large-scale safety interventions. We aimed to assess how much LMICs would benefit from interventions that address six key risk factors related to helmet use, seatbelt use, speed control, drink driving, and vehicle design for safety of occupants and pedestrians. We use a comparative risk assessment framework to estimate mortality and health loss (disability adjusted life years lost, DALYs) that would be averted if these risks were reduced through intervention. We estimate effects for six countries that span all developing regions: China, Colombia, Ethiopia, India, Iran, and Russia. We find relatively large benefits (27% reductions in road traffic deaths and DALYs) from speed control in all countries, and about 5%-20% reductions due to other interventions depending on who is at risk in each country. To achieve larger gains, LMICs would need to move beyond simply learning from HICs and undertake new research to address risk factors particularly relevant to their context.     

Learning lessons: how to practice nudging around the world

Abstract

The aim of this article is to cover three things: (1) to introduce the context behind why a report prepared by the Organisation for Economic Co-operation and Development (OECD) in 2017 would be of such importance to researchers in various academic disciplines and public policy, (2) to present the details of a simple classification system that was applied to all 111 case studies of behavioural interventions (better known as nudges) referred to in the OECD (2017a OECD. 2017a. Behavioural Insights and Public Policy Lessons from Around the World.1-408 pp. OeCD Publishing. https://read.oecd-ilibrary.org/governance/behavioural-insights-and-public-policy_9789264270480-en. doi:10.1787/9789264270480-en.[Crossref] , [Google Scholar]) report, and (3) to discuss what needs to be done to help advance practitioners’ pursuit of effective behavioural interventions. This article aims to highlight the importance of accurately cataloguing the types of behavioural interventions that have been trialled/implemented across the world. By adopting an agreed classification system, researchers and practitioners can benefit from knowing what can work, and where it can work, as well as what does not work, in order to be better armed when considering the use of behavioural interventions to solve social policy issues.     

Financial Frictions,Investment Delay,and Asset Market Interventions

We construct a dynamic macro model to incorporate financial frictions and investment delay. Investment is undertaken by entrepreneurs who face liquidity frictions in the equity market and a collateral constraint in the debt market. After calibrating the model to the U.S. data, we quantitatively examine how aggregate activity is affected by a shock to equity liquidity and a shock to entrepreneurs' borrowing capacity. We then analyze the effectiveness of government interventions in the asset market after such financial shocks. In particular, we compare the effects of government purchases of private equity and of private debt in the open market. In addition, we examine how these effects of government interventions depend on the option to delay investment.     

Urban entrepreneurship through art-based interventions:unveiling a translation process

ABSTRACT

This paper explores the conditions under which urban entrepreneurship can develop through art-based interventions. Drawing on two contrasting case studies (Civic City in France, Fieris Fééries in Belgium) and taking actor-network theory (ANT) as a starting analytical point, we outline the tensions involved in the implementation process of such interventions. We focus on the capacity of urban entrepreneurs to engage different relevant stakeholders (artists, local government and citizens), establish connections between disconnected worlds that are likely to challenge existing institutional structures and eventually create novelty. We identify these actors as ‘translators’. The paper shows that when urban entrepreneurs play an active translation role consistently over time, art-based interventions can have a substantial impact on urban regeneration.     

Heterogeneity and assessment uncertainties in forest characteristics and biomass carbon stocks: Important considerations for climate mitigation policies

The management of forests to store carbon and mitigate climate change has received significant international attention during the last decade. Using in situ data from a 2008–2009 forest inventory field campaign in Sri Lanka, this study describes the structural characteristics and carbon stocks of six natural forest types. This paper has a dual scope: i) to highlight the variation in carbon stored in aboveground biomass within and between forest types and ii) to determine the implications of the allometric equations chosen to calculate biomass carbon stocks. This study concerns work related to climate change interventions, such as Reducing Emissions from Deforestation and Forest Degradation (REDD+) and other forest-related, performance-based initiatives that require proper monitoring, reporting, and verification of carbon stocks, sinks and emissions. The results revealed that forests are heterogeneous in terms of tree density and height–diameter relationships, both between and within the six forest types investigated. The mean aboveground carbon stock in the different forest types ranged from 22 to 181 Mg C ha⁻¹, and there were statistically significant differences in the carbon stocks of the six forest types in 7 of 15 cases. The estimated carbon stock depended heavily on the allometric equation used for the calculations, the variables, and its application to the specific life zone. Due to the diversity of forest structures, these results suggest that caution should be taken when applying default values to estimate forest carbon stocks and emission values in reporting and accounting schemes. The results also indicated the need for allometric equations that are context-specific for different forest types. Therefore, new field investigations and measurements are needed to determine these specific allometric equations, as well as the potential variation in forest carbon stocks in tropical natural forests.
