| Since the first half of the 20th century, the input-output (IO) table has been the backbone of much empirical work used to support policy analysis and develop economy-wide models. The need for accurate, up-to-date IO tables is thus essential for establishing the validity of the empirical work that follows from them. However, the construction of an IO table for any given country is an expensive and time-consuming endeavor. Current and accurate IO tables for many countries are thus often difficult to obtain on a regular basis. Once an initial IO table has been constructed, a common workaround is to collect partial information for subsequent periods, such as final demands for commodities within the economy, and then employ a Bayesian parameter estimation... |

| Climate volatility affects agricultural variability, and extreme climate outcomes have the potential to detrimentally affect food supply and prices in a given country. International trade has the potential to reduce the impacts of climate-induced food production variability, although it may further expose the country to international price volatility. This study focuses on Tanzania and finds that global production volatility currently has very little effect on domestic grain prices due to the country’s limited integration with the international grains market. Almost all the price volatility in grains is attributable to domestic production volatility. At the same time, an export ban that was a response to the 2007-2008 food price crisis increases potential... |

| Climate volatility will increase in the future, with agricultural productivity expected to become increasingly volatile as well. For Tanzania, where food production and prices are sensitive to the climate, rising climate volatility can have severe implications for poverty. We develop and use an integrated framework to estimate the poverty vulnerabilities of different socio-economic strata in Tanzania under current and future climate. We find that households across various strata are similarly vulnerable to being impoverished when considered in terms of their stratum’s populations, with poverty vulnerability of all groups higher in the 21st Century than in the late 20th Century. When the contributions of the different strata to the national poverty changes... |
