Twin Deficits and Twin Decades Jeffrey Frankel Harpel Professor of Capital Formation and Growth Kennedy School of Government Harvard University conference on the Macroeconomics of Fiscal Policy sponsored by the Federal Reserve Bank of Boston, at Wequasett, June 14-16, 2004
Three propositions were put to the test by fiscal expansion of 1980s
tax cuts => big deficits (despite claims to long-run fiscal probity) (Figure 1) part of the problem: overly optimistic forecasts(Figure 4) incl. the Lafferhypothesis: “US tax rate cuts => growth up => tax receipts up” optimistic forecasts soon shattered, although Administration still blames deficits on recession and claims they will go away soon(Figure 5) failure of budget outcomes to follow script => switch to “Starve the Beast” claim “Starve the Beast” claim rings hollow <= WH increases spending(Figure 6) Private saving does not offset deficits => national savingfalls. (Figure 2 or 2b) Economists debate if deficits affect interest rates Fall in national saving reflected in current account deficit. (Figure 3)Twin deficits. (Admittedly, cyclical factors responsible for exaggerating decline in budget, NS, & I at the beginning of decade, but not for overall pattern.) Remarkably close parallels between fiscal expansion of the 1980s and the current decade

Table 2: Feldstein-Horioka Regressions for US -- 1964-2003 • Dependent Variable: Current Account / GDP, Cyclically Adjusted • Coefficient is about 1/2 • Some evidence of upward trend in capital mobility
Differences between the two decades • Differences between early 00s and early 80s: • Interest rates have been low, 2001-2004 • The dollar began to depreciate in 2003 • Not surprising: • The Fed has been very accommodating, so far • Asian central banks, too, have bought US Treasury securities • People are apparently not yet fully aware of the likely magnitude of coming deficits. • Likely to change: i trend will be up
