Pattern of childhood falls in a low-income setting: a cross-sectional study in Dar es Salaam

The objective was to determine patterns and circumstances of childhood falls in a low-income setting in Dar es Salaam, Tanzania. This cross sectional study is based on a household survey conducted in July 2009. A total of 3927 children up to age 18 from 1928 households in 15 sampled wards were surveyed through a structured questionnaire. The current study includes information regarding fall occurrence, socio-demographic and economic factors. Data were analysed using chi-square, t-test and logistic regression. Male children had 42% higher odds of falls compared to females, and rural residents had more than two times higher odds compared to urban residents. Falls occurred three times more among age group 1-4 and two times more among age group 5-9 compared to those between 15 and 18 years. Most falls occurred outdoors (62%) while playing (51%) with boys being over-represented. Females and children aged 1-4 years fell more from stairs whereas most infants fell from furniture. Male gender, younger age groups and rural residence were significant factors for fall injuries. The circumstances in which these falls occur also differ significantly. Intervention efforts should emphasise these patterns.     

Attending to inattention: Identification of deadweight loss under nonsalient taxes

Recent developments in behavioral public economics have shown that heterogeneous biases prevent point identification of deadweight loss. We replicate this result for an arbitrary (closed) consumption set, whereas previous results on heterogeneous attention focused on binary choice. We find that one can bound the efficiency costs of taxation based on aggregate features of demand. When individuals have linear demand functions, the bounds for deadweight loss are easy to calculate from linear regressions.     

Estimation of consistent multi-country FEERs

Most studies on equilibrium exchange rates focus on a limited number of G7 countries. But in a situation of world imbalances, emerging countries can no longer be excluded. The study of all equilibrium exchange rates is delicate. First, the trade model has to be balanced at the aggregate level. This paper suggests a method to achieve world balance both in volume and in value. Second, the N − 1 bilateral exchange rates cannot ensure that the N areas will reach their macroeconomic equilibrium simultaneously. This paper examines the existing solutions to solve the N − 1 problem and proposes an alternative which minimizes the distance to the current-account targets. Finally, in order to compare the relevance of the different methodologies, FEERs are calculated for 19 industrialized and developing countries. The results, which are taking into account the modification on output gap assessment induced by the 2008–2009 crisis, lead for the year 2010 to a USD closed to its equilibrium, a RMB undervalued by around 35% in real effective terms and to a EUR/USD parity equals to 1.47.     

Changes in tourists’ perception of well-being based on their use of emotion regulation strategies during vacation

ABSTRACT

Based on the theoretical foundation of emotion regulation, this exploratory study aimed to examine changes in tourists’ perceived well-being and to determine whether these changes were due to use of emotion regulation strategies (ERSs) during their vacation. This study used travel diaries to record tourists’ use of ERSs on a daily basis, and also measured tourists’ perceived well-being one day before and after their vacation. Results indicated that tourists had significantly higher perceptions of well-being after vacation, and those who used ERSs were more likely to indicate a higher sense of well-being after vacation. The results provide new insight into which aspects of tourists’ subjective and psychological well-being can be boosted by taking vacations and how these aspects may be enhanced by using different ERSs.     

The Effect of Fuel Price Changes on Fleet Demand for New Vehicle Fuel Economy

New vehicle purchases by private companies and government agencies, or ‘fleet’ buyers, represent a significant percentage of overall new vehicle sales in the United States. Yet little is known about fleet demand for new vehicle fuel economy including how it responds to fuel price changes. Using unique disaggregated data on fleet and household registrations of new vehicles from 2009 to 2016, we estimate how fleet demand for new vehicle fuel economy responds to fuel price changes. We find that fleet purchases of low fuel economy vehicles fall relative to high fuel economy vehicles when gasoline prices increase, a finding that is consistent with fleet buyers’ taking into account capitalization of fuel costs in the second‐hand market. Our estimates imply that raising gasoline prices by one dollar would increase fuel economy of new vehicles acquired by fleet buyers by 0.33 miles per gallon. We estimate a similar response for household buyers during the same period. This result justifies basing fuel economy responses to fuel cost changes on household data alone, an assumption widely used in the vehicle demand literature and the fuel economy valuation literature. We also find, however, that the response to fuel price changes varies across the types of fleet buyers: rental companies respond strongly to fuel price changes, whereas commercial and government buyers are insensitive. Our estimates imply that an increase in the federal gasoline tax would modestly increase fuel economy of vehicles bought by households and rental companies but would have little to no impact on fuel economy of vehicles bought by non‐rental companies and governments.     

Does nonagricultural labor relax farmers’ credit constraints? Evidence from longitudinal data for Vietnam

We examine the relationship between participation in nonagricultural labor activities and farming production decisions, focusing on the use of inputs. Using longitudinal data for Vietnam from 1993 to 1998, we find that households engaged in nonagricultural labor spend significantly more on seeds, services, hired labor, and livestock inputs. This is consistent with the hypothesis that nonagricultural labor income relaxes credit constraints to farming.     

The Coal Crisis in Appalachia: Agrarian Transformation,Commodity Frontiers and the Geographies of Capital

Capital's commodity frontiers strategy has at once woven together regional differences within an expanding world‐system and remade the productive and reproductive activities of humans and the rest of nature. The development of successive commodity frontiers gave way to long waves of economic expansion that have been pivotal to accelerating accumulation and transcending capital's recurrent crises. In short, commodity frontiers are constitutive of world‐ecological moments premised on booms and crises of accumulation. In this paper, I examine the coal commodity frontier in Appalachia, to illustrate the region's history as one of succeeding frontiers in and out of the region over the long twentieth century of American capitalism. I argue that the origin of Appalachia's coal frontier was decisively made through the nineteenth‐century agricultural revolution expressed outside of the region. Appalachia's full‐fledged development was an outcome of capital's under‐reproduction strategies. The crisis of the region's frontier turned on a lack of surplus from under‐reproduction strategies, competing coal basins, economic diversification and competing energy sources. I find that the commodity frontier concept not only illuminates regional political economies and ecologies of difference, but also explains the production of nature of historical capitalism.
