× How do perceptions of one’s relative economic status affect gender attitudes, including support for women’s economic participation and involvement in decision-making in their community and household? We conducted a 2018 survey experiment with female and male adults in approximately 1000 households in Papua New Guinea. Employing an established survey treatment to subtly alter respondents’ perception of their relative economic wellbeing, we find that increased feelings of relative deprivation make both men and women significantly more likely to support girls’ schooling and women’s paid employment, suggesting that relative economic insecurity can actually prompt support for women’s economic participation. However, increased feelings of relative deprivation may trigger greater intra-household tension. While increased perceptions of relative deprivation cause women to want more household decision-making authority, men’s attitudes toward women’s proper roles in decision-making are unchanged. In other words, increased support for women’s economic participation among men appears to stem mainly from a desire to raise household income, and not to alter the general role of women in society. The results underscore the multifaceted nature of gender attitudes, and how support for women’s economic participation may rise without simultaneous increases in women’s agency in decision-making.

× A severe El Niño event in 2015/16 decimated an important share of Papua New Guinea's (PNG) local crop production, leaving 10 per cent of the population with significant food shortages. Lack of recent socio‐economic data and analysis of the country's rural population impeded efforts to plan and mitigate the ensuing food crisis. This paper presents the most recent poverty analysis in Papua New Guinea in nearly a decade, and a renewed effort to inform rural production, consumption and livelihood patterns in some of the country's most remote, lowland areas. We designed a rural household survey that collected detailed consumption and expenditure data to explore poverty prevalence and correlates of per capita household expenditure. Results suggest that approximately half of the sampled individuals live in households with total per capita expenditures below the poverty line. Climate shocks have significant and possibly long‐term consequences for household welfare. Households that experienced a drought in the last 5 years are associated with significantly lower per capita expenditures. Labour diversification, via migration, is associated with greater welfare. Households with at least one migrant member are associated with 13 per cent greater per capita expenditure.

× Concerns over the potential effects of the COVID‐19 pandemic have led to trade restrictions by major rice exporters, contributing to an average 25% increase in Thai and Vietnamese rice export prices between December 2019 and March–September 2020. This article assesses the consequences of these rice price increases in Papua New Guinea (PNG), where 99% of rice is imported. Utilizing data from a PNG 2018 rural household survey along with earlier national household survey data, we examine rice consumption patterns in PNG and estimate demand parameters for urban and rural households. Model simulations indicate that a 25% rise in the world price of rice would reduce total rice consumption in PNG by 14% and reduce rice consumption of the poor (bottom 40% of total household expenditure distribution) by 15%. Including the effects of a possible 12% decrease in household incomes because of the COVID‐19 related economic slowdown, rice consumption of the urban and rural poor fall by 20% and 17%, respectively. Maintaining functioning domestic supply chains of key staple goods is critical to mitigating the effects of global rice price increases, allowing urban households to increase their consumption of locally produced staples.

× Background
Papua New Guinea (PNG) experienced positive GDP growth at approximately 4.3% per year during the last decade. With increases in overall wealth within the country, PNG is facing a double burden of malnutrition: comparatively high child stunting rates and a growing overweight and obesity epidemic. We focus on the latter by evaluating trends in agri-food import data from 2001 to 2018 and household consumption data from 2018 and 2009/10.

Results
The analysis presented in this paper raises three red flags. First, international food import data suggest that the demand for ultra-processed, sugar-sweetened beverages and food have increased substantially over time in PNG. Sugar-sweetened beverages dominated the largest growth in processed food imports, increasing by 23% per capita per year between 2001 and 2018. Second, households across the country with a greater food expenditure on sugar-sweetened beverages have a higher probability of an overweight child (under 5 years old). Last, the probability of soft-drink consumption in PNG increases with greater income acquisition and improved market access. While the price of a soft drink is negatively correlated with the quantity consumed, analysis suggests that total household income has a quantitatively larger (and positive) association with soft drink consumption.

Conclusions
Taxing (or increasing taxes on) sugar-sweetened beverages may not be a sufficient policy mechanism to curb overconsumption of soft drinks in PNG. Education and advocacy programs should be fostered that integrate improved dietary information on packaging, as well as greater access to and understanding of nutrition and diet information of common household consumption items. While increases in household income and market access are crucial to economic growth and transformation, PNG’s economic transition must be dovetailed with programs that expand and enhance health and nutrition information and education to improve household consumption decisions and overall household wellbeing.

× Background and Objectives: Fortifying commercial table salt with iodine is the principal strategy used globally to prevent dietary iodine deficiency. However, the costs of providing fortified salt to remote communities may result in it not being locally available or too expensive for many households. This study shows that barriers to consuming adequately iodized salt remain significant for remote rural households in Papua New Guinea (PNG). Methods and Study Design: Using data from a rural household survey conducted in four areas of PNG in 2018, two issues are examined. First, we contrast the characteristics of households that reported consuming or not consuming iodized table salt, respectively. Second, the adequacy of the iodine content of samples of table salt consumed was assessed in the laboratory. Results: Nine percent of the 1,026 survey households reported not consuming iodized table salt. These households tend to live in remote communities, are among the poorest households, have received no formal education, and have experienced recent food insecurity. Second, 17 percent of the 778 salt samples tested had inadequate iodine. The brand of salt most commonly consumed had the highest share of samples with inadequate iodine levels. Conclusions: Particularly in remote communities, ensuring that individuals consume sufficient iodine will require going beyond salt iodization to use other approaches to iodine supplementation. To ensure that the iodine intake of those using commercial table salt is adequate, closer monitoring of the iodine content in table salt produced or imported into PNG and enforcement of salt iodization regulations is required.

× Papua New Guinea is an economic leader in the Pacific region via its extractive resources. However, these industries do not provide employment opportunities for the country’s 6.4 million (80% of total population) rural inhabitants. Rural nonfarm enterprises (NFEs) could offer an additional source of structural change, whereby benefits are capitalized by domestic rural and urban households along the value chain. In 2018, we administered a survey to over 1000 households to gauge whether households with NFEs afford better diets. We examine the factors associated with NFE ownership using a multinomial logit (MNL) framework. We then evaluate whether welfare effects differ by the sex of the NFE owner using nearest neighbor matching to address selection into NFE ownership. Results suggest households with a NFE obtain greater levels of consumption on the order of 26% for protein per person, 11% for kilocalories per person, 13% for total yearly expenditures per person, and 10% for household dietary diversity. Results point to the resounding limitations of female-owned NFEs primarily created to cope with income risk. The findings highlight the relevance of NFEs as a poverty reduction strategy and the importance of targeting when promoting in-country entrepreneurship.
