Predictions With and Without Confidence Intervals: Puerto Rico Post-Maria

Compare this assessment (5/31/2018):

Thus, the data suggests that the hurricane accelerated the deaths of ill and dying people, rather than killing them outright. I would expect the excess deaths at a year horizon (through, say, Oct. 1, 2018) to total perhaps 200-400. Still a notable number, but certainly not 4,600.

With a contemporaneous prediction:

From the survey data, we estimated a mortality rate of 14.3 deaths (95% confidence interval [CI], 9.8 to 18.9) per 1000 persons from September 20 through December 31, 2017. This rate yielded a total of 4645 excess deaths during this period (95% CI, 793 to 8498), equivalent to a 62% increase in the mortality rate as compared with the same period in 2016.

Of course, there is a carrying cost to storage for many commodities, like soybeans (deterioration of stock, direct storage costs, opportunity cost of capital tied up in commodity). Hence, while storage can mitigate losses, it does not necessarily eliminate economic losses that arise from persistent tariffs.

EconoFact: “Threats to U.S. Agriculture from U.S. Trade Policies”

EconoFact, today:

The agriculture sector in the United States depends upon exports for its vitality. Sales of U.S. agricultural products abroad are responsible for 20 percent of U.S. farm income, supporting more than one million American jobs on and off the farm, according to the U.S. Department of Agriculture. The three biggest buyers of American agricultural products are China, Canada, and Mexico. Yet trade with these three countries faces heightened uncertainty. The Trump Administration is in the process of renegotiating the North American Free Trade Agreement (NAFTA) with Canada and Mexico, which includes the option of exiting the deal altogether. In addition, the United States imposed a number of sanctions on our other trading partners, including China. These sanctions have spurred retaliation that has already harmed some agricultural exports.
