Revisiting the demand and profitability of chemical fertilizers amid global fuel-food-fertilizer crisis: Evidence from Ethiopia

Revisiting the demand and profitability of chemical fertilizers amid global fuel-food-fertilizer crisis: Evidence from Ethiopia

We revisit the state of smallholder fertilizer demand and profitability in Ethiopia in the face of the recent global fuel–food–fertilizer price crisis triggered by the Russian–Ukraine war and compounded by other domestic supply shocks. We first examine farmers’ response to changes in both fertilizer and food prices by estimating price elasticity of demand. We then revisit the profitability of fertilizer by computing average value–cost ratios (AVCRs) associated with fertilizer application before and after these crises. We use three-round detailed longitudinal household survey data, covering both pre-crisis (2016 and 2019) and post-crisis (2023) production periods, focusing on three main staple crops in Ethiopia (maize, teff, and wheat). Our analysis shows that fertilizer adoption, use, and yield levels were increasing until the recent crises, but these trends seem halted by these crises. We also find relatively large fertilizer price elasticity of demand estimates, ranging between 0.4 and 1.1, which vary across crops and are substantially larger than previous estimates. We find suggestive evidence that households with smaller farm sizes are relatively more responsive to changes in fertilizer prices. We also document that farmers’ response to increases in staple crop prices is not as strong as perceived and hence appears to be statistically insignificant. Finally, we show important dynamics in the profitability of chemical fertilizer. While the AVCRs show profitable trends for most crops, the share of farmers with profitable AVCRs declined following the fertilizer price surge. Our findings offer important insights for policy focusing on mitigating the adverse effects of fertilizer price shocks.

Buyers’ response to third-party quality certification: Theory and evidence from Ethiopian wheat traders

Buyers’ response to third-party quality certification: Theory and evidence from Ethiopian wheat traders

When quality attributes of a product are not directly observable, third-party certification (TPC) enables buyers to purchase the quality they are most interested in and reward sellers accordingly. Beyond product characteristics, buyers’ use of TPC services also depends on market conditions. We study the introduction of TPC in typical smallholder-based agriculture value chains of low-income countries, where traders must aggregate products from many small-scale producers before selling in bulk to downstream processors, and where introduction of TPC services has oftentimes failed. We develop a theoretical model identifying how different market conditions affect traders’ choice to purchase quality-certified output from farmers. Using a purposefully designed lab-in-the-field experiment with rural wheat traders in Ethiopia, we find mixed support for the model’s prediction: traders’ willingness to specialize in certified output does increase with the share of certified wheat in the market, and this effect is stronger in larger markets. It, however, does not decrease with the quality of uncertified wheat in the market. We further analyze conditions where traders deviate from the theoretically optimal behavior and discuss implications for future research and public policies seeking to promote TPC in smallholder-based food value-chains.

Measuring land rental market participation in smallholder agriculture can survey design innovations improve land market participation statistics?

Measuring land rental market participation in smallholder agriculture can survey design innovations improve land market participation statistics?

The emergence of rural land rental markets in Sub-Saharan Africa is recognized as a key component of the region’s ongoing economic transformation. However, the evidence base on land market participation relies on survey-derived measures, which do not always cohere when compared and triangulated, suggesting the possibility of non-trivial measurement error. We report the results of a priming and list experiments designed to shed light on a persistent mystery in rural household survey data from Africa: why there are so many fewer self-reported landlords (renters-out) than tenants (renters-in)? Our design addresses two hypotheses using experimental data from Ethiopia. First, rented-out and rented-in land may be systematically underreported because enumerators and respondents are typically primed to emphasize parcels that are actively managed/cultivated by the household. Second, rented or sharecropped-out land may be systematically underreported because of respondents’ reluctance to acknowledge an activity for which public disclosure may have negative repercussions. We address the first hypothesis with a priming experiment by exposing a random subset of respondents to a nudge that explicitly reminded them to fully account for all land, including rented/sharecropped-in and rented/sharecropped-out. We address the second hypothesis with a double-list experiment, designed to elicit true rates of land renting and sharecropping-out. We find that nudging induces about 4 percentage points increase (or 13% in relative terms) in the share of households participating in renting in or sharecropping-in practices but has negligible effects on reported rates of renting and sharecropping-out. Interestingly, our list experiment indicates much higher revealed rates of renting-out (14-15%) than is reflected in the nominal parcel-roster responses (3%). The magnitude of the latter finding fully explains the apparent difference in renting in versus renting-out rates derived from the regular parcel roster responses. These results indicate that efforts to document land market participation rate and associated impacts must overcome large systematic reporting biases.
