Feeding the planet by 2050

9.2 billion is the estimated number of individuals that the planet will have to feed by 2050. We estimate an economic model able to replicate the main features of the nutrition transition, which characterizes the evolution of diet with per capita income: rise in calorie consumption with increased income, diversification from starchy staples, and increased caloric demand for animal-based products, fats, and sweeteners. We use this model to project global food demand between 2010 and 2050. We predict an increase in caloric demand of 46% for 2050, mainly attributable to low-middle and low income countries. Using alternative projections of populations and revenues shows large uncertainties in the rise of demand for animal-based (alt. vegetal-based) calories, ranging from 78% to 109% (alt. 20% to 42%).

Export price, tariff and exchange rate: the international elasticity puzzle is worse than you think

Unfair competition or exchange rate manipulations are recurrently used as arguments to justify retaliatory tariffs. The answers in the economic literature are incomplete or puzzling, and there is no consensus on the value the elasticity to trade costs In a recent paper, we shed new light on this debate by putting firm-level export prices explicitly at the centre of the analysis of the international elasticity puzzle (Fontagné et al. 2017). Our results, based on French firm-level data, confirm that, when estimated at the firm level, the tariff elasticity is higher (around 2) than the exchange rate elasticity (less than 1). This is the standard international elasticity puzzle. We go further by showing that the export price elasticity is even larger (around 5) than both the tariff and the exchange rate elasticities.
