Do IMF stabilization programs increase (decrease) the likelihood of a currency crisis?
Article I IMF: Promote Stability of Exchange Rates and Currency Markets
IMF Failures in the 1990s: Russia, Indonesia; “Abolish” IMF: for e.g. Stiglitz
IMF’s record in preventing currency crisis (not crisis resolution) is “mixed”

What explains variation in Effect of IMF Programs on Currency Crises?
Scholars examine how IMF programs affect macroeconomic outcomes, e.g. growth (Barro,
Dreher, Vaubel, Stone, Vreeland), but not currency markets.
Political Scientists..…study how domestic institutions affect currency/financial markets
(Leblang; Bernhard; Freeman; Hays; Satyanath)…. how international institutions such as
WTO affect trade (Mansfield, Reinhardt; Goldstein,Tomz & Rivers; Gowa & Kim).
Answer: Impact of IMF programs on likelihood of currency crisis conditional on extent of
institutionalized state intervention in borrowing country’s financial sector.
Greater (lesser) the state’s role in the financial sector of the borrowing country’s financial
sector, the higher (lower) the likelihood that IMF loans under its stabilization programs will
lead to a currency crisis.
Model of Speculative Trading
3 Players: Currency traders, IMF, Debtor Country (financial problems but not
fully blown currency crisis) that borrow IMF loans
Macroeconomic fundamentals of debtor country; s = signals about
Currency Trader’s Payoff:

Causal Story….
Higher state intervcntion in financial sector of debtor country…
Greater political resistance to financial reforms suggested by IMF
Ex ante commitment to implement reforms lack credibility &
IMF loan/program engenders moral hazard under weak commitment
Declining fundamentals = speculative attack =currency crisis
H1: IMF stabilization programs engender “moral hazard” in borrowing countries
with high state intervention in financial sector
H2: IMF stabilization programs increases likelihood of currency crises in borrowing
countries with high state intervention in financial sector
Sample and Statistical Model
82 countries, 1974-2002
2 Methodological Issues:
Non-random participation in IMF programs (selection)
spatial dependence in likelihood of currency crisis & participation in IMF program

Key Variables
DV in outcome equation: Currency Crisis =1 if change in index of exchange
rate pressure exceeds mean plus 2 times the country specific std deviation.
Index: weighted average of real exchange rate changes and % reserve losses
IV in outcome equation interaction term: IMF Program x State Credit/GDP
IMF Program dummy for IMF loans provided for short-run financial
stabilization via SBAs, BSFF, CSF, SRF, CFF and EFF; Not PGRF and SAF
State Credit/GDP: Share of State Owned Credit GDP; Proxy for state
intervention in financial sector
Several Controls in Selection and Outcome equation: M2/Reserves, Divided
Government, Terms of trade growth, external debt….

Conclusions & Future Research
Effects of IMF programs on currency markets –especially the
likelihood of currency crisis – not direct
Conditional on state’s role in financial sector
Study more closely the details of the IMF programs, how
financial markets and domestic politics in debtor countries
respond to these programs
Gather additional data as well
