Evaluation of Non-Survey International IO Construction Methods with the Asian-Pacific Input-Output Table

This paper presents four non-survey methods to construct a full-information international input-output table from national IO tables and international import and export statistics, and this paper tests these four methods against the semi-survey international IO table for nine East-Asian countries and the USA, which is constructed by the Institute of Developing Economies in Japan. The tests show that the impact on the domestic flows of using self-sufficiency ratios is small, except for Singapore and Malaysia, two countries with large volumes of smuggling and transit trade. As regards the accuracy of the international flows, all methods show considerable errors, of 10%-40% for commodities and of 10%-70% for services. When more information is added, i.e. going from Method 1 to 4, the accuracy increases, except for Method 2 that generally produces larger errors than Method 1. In all, it seems doubtful whether replacing the semi-survey Asian-Pacific IO table with one of the four non-survey tables is justified, except when the semi-survey table itself is also considered to be just another estimate.

Diversities and Disparities among Female-Headed Households in Rural Malawi

Using data obtained from a survey carried out in six villages in various parts of rural Malawi, this paper examines some of the main characteristics of female-headed households. In the study villages, most female-headed households are in a disadvantageous position relative to their male counterparts in terms of labour endowment, farm size, and agricultural productivity. The high cost of inputs, especially of fertilizer, prevents resource-poor female-headed households from improving maize self-sufficiency through increased productivity and from engaging in high-return agriculture such as tobacco production. The paper also shows that there are marked disparities within the category of female-headed households. Factors that enable some female-headed households to achieve high income include the availability of high-return nonfarm income opportunities, use of social networks to obtain labour and income opportunities, land acquisition through flexible applications of inheritance rules, and the existence of informal tobacco marketing. Livelihood diversification is adopted by both male- and female-headed households, but many of the female-headed households engage in low-return and low-entry-barrier activities such as agricultural wage labour. On the other hand, the high off-farm income in the wealthier female-headed households enables them to purchase fertilizer for own-farm production, contributing to an improvement in productivity and resultant increases in their total income.

Food crop diversification as a risk mitigating strategy during conflict : evidence from Cote d'Ivoire

This study examines the significance of food crop diversification as a household risk mitigating strategy to achieve "self-sufficiency" to ensure food security during the civil conflict in Cote d’Ivoire. The main motivation for seeking self-sufficiency stems from the fact that during the period of heightened tension due to conflict, the north–south divide set by the UN peacekeeping line disrupted the agricultural supply chain from the food surplus zone, Savane in the north. While we theoretically predict a positive effect on crop diversification because of interrupted food supply chain, we also consider a negative effect due to the covariate shocks. We find robust and statistically significant empirical outcomes supporting such claims. The baseline outcomes withstand a series of robustness checks. The net effect of conflict on crop diversification is positive but not statistically significant. In addition, we find that increasing vulnerability to poverty and food insecurity during conflict seems to be the underlying factors that motivate farm households to adopt such coping strategies.
