The purpose of this paper is to estimate both direct and indirect channels through which imported inputs spur exporting in the African manufacturing sector.

Design/methodology/approach

The authors estimated models for all exporters, direct exporters and indirect exporters using a probit model. The authors circumvented the endogeneity of imported inputs and productivity in the export status models by using their lagged values. The authors employed the World Bank Enterprise Survey data for a set of 26 African countries.

An extensive line of research has examined linkages among spatially‐distinct markets. We apply semi‐parametric, generalized additive vector autoregressive models to a consideration of basis linkages among North Carolina corn and soybean markets. An extensive suite of linearity tests suggests that basis and price relationships are nonlinear. Marginal effects, transmission elasticities, and generalized impulse responses are utilized to describe patterns of adjustment among markets.

Recent reports indicating that large portions of land (estimated 50-80m hectares) have been bought by international investors in middle- and low-income countries, with roughly two-thirds of those purchases occurring in sub-Saharan Africa, calls for a cursory appraisal of the implications of the trend of land grabbing for West African food security.

This study determined the adaptation and coping strategies adopted by farmers under yam- and cassava-based farming systems in Ebonyi and Enugu States in Nigeria's derived savannah agro-ecological zone. The study uses data from 400 farmers. The likelihood that the farmers engage in some actions to cushion the effect of climate change was determined using a probit model and a multi-nomial logistic regression. The results of the study revealed that the main outcomes of climate change were flooding (71.29%), decline in crop yields (65.1%), food price increases (62.87%), and food
