Analyzing Water Scarcity in Global CGE Models

08 Sep 2017 | Contributor(s): Jing Liu, Tom Hertel, Farzad Taheripour

Incorporating water into a computable general equilibrium (CGE) model operating at global scale can be extremely demanding due to the absence of standardized data, the sheer dimensions caused by intersecting river basins with countries, and difficulties to model demand for and supply of water....

Predicting Long Term Food Demand, Cropland Use and Prices

08 Sep 2017 | Contributor(s): Tom Hertel, Uris Lantz C Baldos, Dominique van der Mensbrugghe

This paper seeks to survey, understand and reconcile the widely divergent estimates of long run global crop output, land use and price projections in the current literature. We begin by reviewing the history of such projections and the different models and assumptions used in these exercises. We...

Debunking the 'New Normal': Why World Food Prices are Expected to Resume their Long run Downward Trend

08 Sep 2017 | Contributor(s): Uris Lantz C Baldos, Tom Hertel

Contrary to the opinions expressed by many commentators, the recent episode of higher prices for agricultural commodities is likely a transitory phenomenon. When compared to the last half-century, population growth is expected to be much slower in the coming decades, with nearly all of the growth...
