An Approach Paper on Indo-US Trade in Wheat and MangoA Game Theoretic FrameworkSatish Y. Deodhar (IIM-A)Siddharth Rastogi (IIM-A)International Agricultural Trade Research Consortium meetingsJanuary 6-9, 2008
Synopsis • Motivation for the study • Literature Review • Product Choice • Methodology: A Game Theory Approach • Data scouting • Potential for Policy Implications
Motivation • WTO: Quota & tariffs going down in ag trade • NTBs: SPS issues coming to the fore • Sanitary and phytosanitary (SPS) measures • There is a separate SPS agreement under WTO • What do SPS restrictions on imports do? • Protect producers from negative externalities arising from invasive pest, weeds, organisms • However, it also protects domestic producers from foreign competition! • Thus, impact assessment becomes important • But how to go about doing it?
Literature Review • FAO (2001): Lists six types of impacts • Impact on production, price & market, trade, food security & nutrition, human health & environment, and, financial cost • Surveys and interviews • E.g., Mutasa & Nyamandi (1998) • Taking inventory of SPS restrictions & cases • E.g., Wilson & Otsuki (2001) • Price Wedge models • Calvin & Krissoff (1998) • Japanese apple imports into US
Literature Review … • Gravity Models • Study of bilateral flows to identify NTB related trade restriction • E.g. Otsuki, Wilson, and Sewadeh (2000) • Iso-Risk framework • E.g., Bigsby (2001). Pest Risk = Eco. Impact times Probability of pest Introduction • Cost-Benefit analysis • Studies on banana and avocado • E.g., James and Anderson (1998), Peterson and Orden (2006) • Measure compliance cost and expected net welfare changes
Limitations • Some studies measure only qualitative impact • Some use SPS case statistics – not based on science/economics • Some other measure only the trade restriction or expansion • Yet others look at cost of compliance and expected welfare, but use single commodity, single country framework • Reality is a little different
Strategic Interaction • Countries get engaged in bilateral negotiations • Countries get engaged in multilateral negotiations (WTO rounds) • Strategic give-and-take across commodities • E.g., agree to reduce subsidies against geographic indications for wine • Thus, studies in isolation for each commodity and country may not represent true picture • Policy choices are interdependent
Trade in Wheat and Mango • Wheat: • US production and exports are about 50 and 25 million tonne • In 2007 India imported 6.7 million tonne • None from US ! (Phytosanitary restrictions) • Mango: • India’s production and exports are 10 and 0.8 million tonne (2006) • US imported mangoes worth $233 million but none from India • Fear of Fruit fly and weevil
President Bush • During his trip to promote bilateral trade in 2006: • “By the way Mr. Prime Minister, the US is looking forward to eating Indian mangoes.” • Probably what he really meant was: • “By the way Mr. Prime Minister, the US is looking forward to sending some US wheat to India.”
If Net welfare is positive for imported good, • Complete liberalization is dominant solution • If Net welfare is sufficiently negative for imported goods i.e., U+A-B <0, V+X-Y<0 • Import ban is the dominant solution • If Net welfare is negative for imported goods, but U+A-B and V+X-Y are positive • Prizoners’ dilemma occurs • Repeated game signals might work
Data Analysis for the payoffs • Risk Assessment • Need to get probabilities of pest invasion, crop loss, spillovers • Estimate magnitudes of losses • Risk Management • Evaluate mitigation options • Evaluate liberalization degree
