  2. Spatial and temporal distribution of optimal maize sowing dates in Nigeria by Mkuhlani, S., Bendito, E.G., Tofa, A.I., Aliyu, K.T., Shehu, B.M., Kreye, C., Chemura, A.

    Published 2024
    “…The results show that optimum sowing dates significantly vary across the country with northern Nigeria having notably delayed sowing dates compared to southern Nigeria which has earlier planting dates. The long-term optimal sowing dates significantly (p<0.05), shifted between the 1980s (1981–1990), and current (2011–2019), for most of the country. …”

    Published 2004
    “…This study computes nominal protection rates and producer support estimates (NPR and PSE) for Indonesia for the period 1985-2003 for six agricultural commodities, rice, maize, sugar, soybeans, crude palm oil, and natural rubber (representing more than two-thirds of Indonesian agricultural output) in an attempt to quantify the net effects of these policies. …”

  10. Estimating income mobility in Colombia using maximum entropy econometrics by Morley, Samuel, Robinson, Sherman, Harris, Rebecca Lee

    Published 1998
    “…Income mobility can be viewed as a first-order Markov process, with a matrix of transition probabilities which measure how individuals move from an income status in time t to a new status in time t+1. Direct estimation of transition matrices is difficult, since time series panel data are unavailable and limited data on the distribution of income do not suffice to determine the coefficients mathematically, let alone provide enough degrees of freedom for estimation. …”

  11. Estimating the impact of agricultural technology on poverty reduction in rural Nigeria by Omilola, Babatunde

    Published 2009
    “…This paper argues that any changes in poverty situation attributed to those who adopt new agricultural technology (treatment group) without a counterfactual comparison of carefully selected nonadopters (control group) are likely to be questionable. The paper estimates the effects of new agricultural technology on poverty reduction by employing the “double difference” method on data collected in rural Nigeria. …”
