Spatial integration at multiple scales: rice markets in Madagascar (2009, neutral): “See, for example, Fackler and Tastan (2008).”
Asymmetric price transmission in the Spanish lamb sector (2007, background): “…have either considered one threshold (λ1) to separate the adjustment process into two regimes (Balke and Fomby, 1997; Enders and Granger, 1998, Abdulai, 2000 and 2002, Hansen and Seo, 2002) or two thresholds (λ1 and λ2) to separate the adjustment process into three regimes (Obstfeld and…”
Local polynomial fitting and spatial price relationships: price transmission in EU pork markets (2006, background): “As Abdulai (2000) noted, if middlemen have market power, they may react more quickly to shocks involving a reduction in their marketing margins than to shocks increasing them.”
Asymmetric Price Transmission: A Survey (2004, methodology): “A further cause of spatial APT that is often cited in the context of developing countries is that of asymmetric flows of information between central (hub) and peripheral (spoke) markets (Abdulai, 2000).”
Econometric models of asymmetric price transmission (2007, positive): “One recent contribution in this direction is Abdulai (2000), who studies the Ganan market of maize during the period May 1980-October 1997.”
