Some context for the semester ahead:The world food and financial crisis of 2007-09

Thurs., August 28, 2014
?Our goal for today:
much data, a few hypotheses
The 2007-09 crises, in one picture
DBA index = four major crops, in US dollars
USD index = six major currencies, per US dollar
Source: Computed from data at www.google.com/finance.Note: The DBA index is corn, wheat, soy and sugar (25% each). The USD DNX index is the currencies of Europe (57.6%), Japan (13.6%), Britain (11.9%), Canada (9.1%), Sweden (4.2) and Switzerland (3.6%), per US dollar. The S&P 500 is a value-weighted sum of large U.S. companies.
S&P500 index = all major companies, in US dollars
all rise commodities rise as stocks fall all fall, then
move together
Our goal for today: much data, a few hypotheses

Let’s start with the economy as a whole

Note typical spike-and-valley pattern
Rice rose first and spiked highest
Other crops rose/fell in sync

Data shown are an index of export prices in US dollars for all major traded agricultural products, deflated by the MUV index which is the unit value of manufactures exported from France, Germany, Japan, UK and US, with weights based on those countries’ exports to developing countries.

The spike-and-valley pattern creates cycles of panic and then complacency
The 1973 crisis led to investments that brought prices down to unusually low and stable levels

Local crises are driven by underlying world market conditions and local “stochastic” events

Note: All data are from the Kagera Health and Development Survey (www.worldbank.org/lsms); results shown are a local polynomial regression with its 95% confidence interval, for surveyed households with agricultural production (579 in 1991-92, and 557 in 1992-93). Staple food crops are maize, cassava, cooking bananas, millet, sorghum, and yams or potatoes. The household’s expenditure per capita is measured in 2006 U.S. dollars converted at PPP prices.

Whew! Conclusions?
• There’s a lot of data out there– not everything is measured, but much is known– relationships between variables remain questionable
• Hw #1 will give you experience using those data– write-ups should describe what you see in the data;
inferring causality is risky (avoid saying “because”); it is far more honest to speak of “association”
• Next week, we begin systematic search for links between economic growth, agricultural development and government policies…
