Reducing food insecurity remains a major public policy challenge in developing countries. Food insecurity becomes severe in areas where households highly depend on undiversified livelihoods. However, studies linking household income diversification to food security are limited. This study, therefore, examined the effect of income diversification on food security in the Ambo district, Ethiopia. A survey of rural (n = 175) and semi-urban (n = 175) households was conducted. The Simpson’s index of diversity (SID) was used to measure the level of household income diversity. Food security (access) was measured using the daily calorie consumption (nutrition-based) and the household food insecurity access scale (HFIAS) (experience-based) methods. Consequently, we used binary logistic regression and ordinary least squares (OLS) estimation methods to determine the effect of household income diversity on food security. The instrumental variable (IV) method was also employed to overcome an endogeneity bias. The results revealed that the level of household income diversification was low, and the majority of households were food insecure. The binary logistic and the second-stage least square (2SLS) regression results suggested that income diversification contributes significantly and positively to food security in the study areas. Therefore, we conclude that income diversification reduces food insecurity by enhancing households’ access to food.

Local marketplaces are remarkable organizations for agricultural product transactions in Ethiopia. However, little is known concerning measurement practices in these micro-trading zones. Thus, this study intended to examine the cereal commodity quantity measurement behaviors of farmers in the local marketplaces of Ethiopia. A survey was conducted in four districts marketplaces (N = 382) of the Oromia Region. The χ² test was employed to evaluate the association between farmers’ perception of the accuracy of local units and measuring instruments related to immoral buyers’ behaviors. According to the findings, farmers’ cereals quantity measurement behaviors proved the presence of unreliability which created transaction, measurement, social capital, and two-hand palm cereals gift costs. The χ² test results indicated that farmers’ perceptions of the accuracy of local units and measuring tools related to buyers’ unethical behaviors had significant relationships with bowl, glass, sack, and can local units, except for weight balance in Dendi and Bako Tibe, and for cans in the Gimbichu area. This study demonstrates that standardization of tools and measurements, together with institutional support, would have a huge potential for economizing transaction costs and making equitable cereals exchanges and efficient markets.

Peasants’ calculation capacities (PCC) and measurement behaviors can enable the development of knowledge economy and technological exchanges. This study is based on critical observations made by analysis of Chinese and Ivorian rural markets to understand measurement system as a foundation of development of economic knowledge, science, and technology. A total of 167 rural people from China and Cote d’Ivoire were interviewed using a simple random sampling method through valid and reliable means. Using the univariate statistics, we summarized the data to statistically describe Chinese and Ivorian rural traders. The multiple linear regression model was used to examine the impact of different explanatory variables on peasants’ calculating capacities. From the independent two samples t-test, we statistically examined the difference between the calculation capacities of Chinese and Ivorian rural traders. Analysis of the data from China and Cote d’Ivoire showed that 76% of Chinese rural traders were using traditional or modern weighing balance compared to only 24% in Cote d’Ivoire. Modern or traditional weighing balance was popular only with traders or wholesalers dealing with bulk commodities, or traders with expensive products in the case of Cote d’Ivoire. Our findings also depict that the calculation capacities of Chinese rural traders are higher than Ivorian (p-value < 0.001). Experience was found to be the most effective factors for the estimation of PCC among Chinese and Ivorian rural traders. Together, these results significantly expand the knowledge, economy, and technology adoption issues in the context of China and Cote d’Ivoire. Thus, our analyses provide useful insights for policymakers, rural traders, advisers, for decision making and agricultural extension services in these two countries, particularly for China–Africa cooperation.

Measurement reliability is an undervalued aspect of local agricultural marketplace organizations. There are also gaps in identifying the extent of cereal commodity trade measurement costs. Therefore, the aim of this paper is to estimate the magnitude of cereals trade quantity measurement cost caused by instrument error and unreliability in the context of the local marketplace in Ethiopia. In this regard, a survey was conducted in six different districts’ marketplaces (n = 602) of Oromia regional state. In addition to administered structured questionnaires, site mass measurement calibration was employed. The survey data were analysed using an independent samples t-test, one sample t-test and analysis of variance. According to the findings, the actual value measurement means of the quantity of most local units of the farmers were greater than small traders. The independent t-test result indicated that the average values of the quantity of the majority of units of measurement between farmers and small traders were varied significantly. Estimated average measurement cost of the farmers and small trader which occurred due to measuring instruments’ error and unreliability were higher for a sack, bowl and glass units compared with other units of measurement. This study demonstrates that homogeneity in measurement, market regulatory policy and institutions that aid cereals trade have an indispensable role to reduce measurement costs thereby ensure equitable exchange.

The issue of measurement reliability is certainly undervalued in the local agricultural marketplace organization. Besides, there was nothing identified concerning the extent of cereal commodity trade measurement cost. Hence, this paper aimed to estimate the magnitude of cereals trade quantity measurement cost caused by instrument error and unreliability; mainly by targeting the local marketplace in Ethiopia. The survey was conducted in six different districts’ marketplaces (n = 602) of Oromia region by employing administered structured questionnaires and site mass measurement calibration. The gathered data were analyzed using independent samples t-test, one sample t-test, and analysis of variance. According to the findings, the actual value measurement means of the quantity of most local units of the farmers were greater than small traders. The independent t-test result indicated that the average values of the quantity of the majority of units of measurement between farmers and small traders were varied significantly. Estimated measuring instruments’ error and unreliability associated average measurement cost of one-day market transaction over total cereals marketed amount were higher comparatively for a sack, bowl, and glass units. This study demonstrates that homogeneity in measurement, policy, and institutions that aid cereals trade would have an indispensable role to reduce measurement costs and ensure equitable exchange.
