Harvest Shortfalls, Grain Prices, and Famines in Pre-industrial England

1 Fresh data on English grain yields 1268-1480 are combined with revised price series to measure the frequency and scale of serious harvest shortfalls and estimate the elasticity of demand for cereals. Major food availability declines are shown to have been a significant component of most historical subsistence crises, as back-to-back shortfalls were of the worst famines. Although farmers did a...

Assume that at the beginning of game t, the system's belief in the user's preference is P t. Then, the certainty-equivalet user preference during game t is π * t (i) = E π∼Pt [π(i)] ∀i ∈ I. Recall we define π * min = min i∈I π * (i), Lemma A-1 formalizes the result that if π * t is " close " to π * , then for any decision tree T , E i∼π * t [N (T, i)] is " close " to E i∼π * [N (T, i)]: Lemma A...

We wish to reduce the number of parameters in the model and make it so that the model is more easily comparable to our previous work [1]. To do this we first look at the nonspatial single morph model which is given by: Ni(t+ 1) = (1 + b)Ni(t) exp(−mi −mi (1 + b)Nt) For the purpose of this model we want the carrying capacity K to be fixed by the equilibrium population density. We therefore calcu...

Our primary source for climate data is the Terrestrial Air Temperature and Precipitation: 19002006 Gridded Monthly Time Series, Version 1.01 (2007), compiled by Kenji Matsuura and Cort Willmott in conjunction with NASA. The data are available at http://climate.geog.udel.edu/ ~climate/html_pages/download.html. This dataset combines station data on mean air temperature and precipitation from a nu...
