    Oil price shocks and human capital channels in Nigeria by Olabisi Rasheedat Oladipo, Abiola John Asaleye, Ademola Andrew Onabote, Damilola Felix Eluyela, Rotimi Ayoade Ogunjumo, Joseph Olufemi Ogunjobi, Olufemi Adebayo Oladipo, Stephen Adesina Ibitowa

    Published 2024-12-01
    “…While many studies have investigated the relationship between oil price volatility and human capital development, few have examined how this relationship impacts both basic and advanced human capital channels in developing economies; this study addresses that gap by using a Structural Vector Auto Regression (SVAR) approach to investigate how oil price shocks influence human capital channels. Co-integration tests reveal significant long-term relationships among the variables. …”

    Two Weighted Fuzzy Goal Programming Methods to Solve Multiobjective Goal Programming Problem by Mousumi Gupta, Debasish Bhattacharjee

    Published 2012-01-01
    “…Here, the relative weights represent the relative importance of the objective functions. The proposed methods involve one additional goal constraint by introducing only underdeviation variables to the fuzzy operator λ (resp., 1-λ), which is more efficient than some well-known existing methods such as those proposed by Zimmermann, Hannan, Tiwari, and Mohamed. …”
