Abstract
We quantify the relationship between Tanzanian and external maize markets while
also accounting for domestic influences. We conclude that external influences on domestic
prices originate from regional, rather than global, markets. We also show that,
compared to external factors, domestic factors exert a greater influence on Tanzanian
maize markets. Further, the mechanisms through which trade policies influence maize
markets involve interactions with both external market shocks and domestic weather
shocks. Overall, we provide evidence that the intermittent imposition of export bans
in Tanzania has had adverse impacts on its maize markets, and consequently, on the
development of its agrarian economy.
