This study quantifies the relationship
between Tanzanian and external maize markets while also
accounting for domestic influences. It concludes that
external influences on domestic prices originate from
regional, rather than global, markets. It also shows 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, it provides
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.
