Book Description
This paper uses comprehensive and long time series monthly food price data and a panel dyadic regression framework to evaluate the impact of the COVID-19 pandemic and associated policy responses on spatial market integration across a diverse set of food items in Nigeria. The empirical results reveal several important insights. First, we show that a significant slowdown in the speed of adjustment and price transmission occurred during the pandemic. For some food items, the speed of adjustment and, by implication, spatial market integration weakened by two- to-threefold after the pandemic outbreak. The effect was specially pronounced for perishable food items. Second, lockdown measures and the spread of the pandemic triggered additional dispersion in market prices across markets. For example, lockdown measures were associated with a 5–10 percent reduction in the speed of readjustment toward long-term equilibrium. Third, additional underlying attributes of markets, including lack of access to digital infrastructure and distance between markets, exacerbated impacts associated with the pandemic. For instance, access to Internet service reduced the slowdown in the speed of adjustment caused by the pandemic, but longer distances between market pairs induced greater slowdown in the speed of price transmission. Our findings offer important insights for revitalizing the efficiency of food markets affected by the pandemic. The heterogenous impacts of the pandemic across value chains and markets reinforce the need to properly target post-pandemic recovery interventions and investments. Finally, we offer some insights to reduce the vulnerability of food and market systems to disruptions in future pandemics or similar phenomena that inhibit food marketing and trade.

Book Description
This study focused on measuring spatial market integration between urban and rural food markets in South Africa. The study was influenced by continual debate on the issue of high food price increases among the basic agricultural foods which have impact on food price differentials that exists in market locations. Higher food price differentials between market locations can have negative implications for households’ livelihoods. In South Africa the majority of lower-income earners live in rural areas, which implies that the disposable incomes of those households are affected differently by higher price differentials. To ensure that there are lower price differentials between market locations, spatial market integration is required. The main objective of this study was to measure spatial market integration between urban and rural food markets. This objective was achieved through the modelling of secondary price data of the 2.5 kg package of super maize meal. Data used in the study was collected by the NAMC and Stats SA during the period of November 2006 to July 2012. The study used a co-integration model, together with the Vector Error Correction Model (VECM) and the Autoregressive Distributive Lag (ADL) model. The study revealed that out of the nine markets which were measured for spatial integration, six of the rural food markets were co-integrated with urban markets. Estimation of the six co-integrated markets with the VECM revealed a long-run equilibrium relationship between urban and rural food markets. The VECM results further showed different speeds of price adjustments to the long-run equilibrium which was faster (65% on average) in five markets and slower (40 %) in one market. The fast speed of price adjustment to long-run equilibrium relationships suggests that transaction costs have significant effects on markets linkages. Markets also showed different time of adjustments which was between three and five months. Short-run dynamic effects were found in only three markets and could not be established in the other six rural food markets. Price information flow, transportation costs and transaction costs are seen as bottlenecks that prohibit integration of markets in the short run. With regard to price relationships, the study found statistically significant differences between urban and all rural food market mean prices. This suggested that the price of 2.5 kg maize meal was generally high in all rural markets, as compared with urban markets. Markets with very high price increases were those located in the lower production potential areas of the maize commodity. The Impulse Response Function (IRF) was employed to establish the effects of negative and positive price transmission shocks from the urban to the rural food markets. One standard deviation was put into the model to establish the response of markets to shocks. The markets tested revealed a period of between two and eleven months for the negative and positive impulses to be cleared in all the markets. A high degree of spatial market integration was found when negative and positive shocks did not exhibit price diversion from the long-run equilibrium relationship.

Book Description
This paper combines pre-pandemic face-to-face survey data with follow up phone surveys collected in April-May 2020 to quantify the overall and differential impacts of COVID-19 on household food security, labor market participation and local food prices in Nigeria. We exploit spatial variation in exposure to COVID-19 related infections and lockdown measures along with temporal differences in our outcomes of interest using a difference-in-difference approach. We find that those households exposed to higher COVID-19 cases or mobility lockdowns experience a significant increase in measures of food insecurity. Examining possible transmission channels for this effect, we find that COVID-19 significantly reduces labor market participation and increases food prices. We find that impacts differ by economic activities and households. For instance, lockdown measures increased households' experience of food insecurity by 12 percentage points and reduced the probability of participation in non-farm business activities by 13 percentage points. These lockdown measures have smaller impacts on wage-related activities and farming activities. In terms of food security, households relying on non-farm businesses, poorer households, those with school-aged children, and those living in remote and conflicted-affected zones have experienced relatively larger deteriorations in food insecurity. These findings can help inform immediate and medium-term policy responses, including social protection policies aiming at ameliorating the impacts of the pandemic, as well as guide targeting strategies of governments and international donor agencies by identifying the most impacted sub-populations.

Book Description
The Pradhan Mantri Kisan Samman Nidhi (PM-KISAN) scheme aims to provide income support to farmers to facilitate timely access to inputs by easing their liquidity needs. This study, based on 1,406 farmers of Uttar Pradesh and using a binary choice model, examines the scheme’s targeting accuracy and the correlates of farmers’ spending patterns. Triple difference with matching estimators are used to identify the differential impact of PM-KISAN on Krishi Vigyan Kendras (farm science centers, or KVKs) beneficiaries. Results show that PM-KISAN reached to one-third of all the farmers in the first three months of its implementation. Moreover, the study finds no selection bias based on social, economic and agricultural characteristics. The scheme has significantly helped those who are relatively more dependent on agriculture and have poor access to credit. Moreover, scheme has significantly stimulated the KVK ’s impact on the adoption of modern cultivars.

Book Description
Programs that seek to increase women’s participation in marketing activities related to the principal household economic activity must involve men if they are to be successful. In this paper we analyze take-up of a project that sought to increase women’s involvement in sugarcane marketing and sales by encouraging the registration of a sugarcane block contract in the wife’s name. We find that men who are more educated and live in households with higher wealth and expenditures are more likely to agree to the registration. Households with more cane blocks and in which the wife is already more involved in cane activities are also more likely to participate. Overall, take-up is high at 70%, and remains high even in those groups that are less likely to take-up. Additionally, we find that blocks transferred to women are not of lower quality or value than those kept by men, though they are smaller and closer to the home. These results suggest that simple encouragement can be an effective tool to nudge men to include their wives in household commercial activities.
