“…Thus, output growth of sector i in country j depends on the countrywide poverty level (or human development) and FDI, while poverty (or human development) is also a function of SOP (Baldacci et al, 2008). Both HDI and SOP are also affected by the level of capital formation (INV), population growth (POPG), and trade openness (TOPEN) of the economy (Basu & Guariglia, 2007; Jahanger et al, 2022), while governance institution (GOV), proxied by rule of law, is critical to poverty outcomes (Chukwu et al, 2022; Gohou & Soumaré, 2012; Wu & Hsu, 2012). Measuring the sectoral variable i ( i = 1…3) for country j ( j = 1…23) at time t ( t = 1996…2020), and macroeconomic variables for country j at time t , a system of simultaneous relationships can be established as follows: where i in SOP ijt is defined for the agricultural, service and manufacturing output performance (ManP) as AgricP, SerP and ManP, respectively.…”
