We use the Synthetic Control Method to study the effect of IMF advice on economic growth, inflation, and investment. The analysis exploits the existence of IMF programs that do not involve any financing (Policy Support Instruments, “PSIs”). This enables us to focus on the effects of IMF monitoring, advice, and approval (as opposed to direct financial assistance). In addition, countries with non-financial programs are typically not crisis-struck – thereby mitigating the reverse causality problem and facilitating the construction of counterfactuals. Results suggest that treated countries add about 1 percentage point in annual real GDP per capita growth, with inflation being lower by some 3 percentage points per year. While we do not find evidence for an impact on total investment and the resulting capital stock, PSI-treatment does seem to stimulate foreign direct investment.

Evaluating the Impact of Non-Financial IMF Programs Using the Synthetic Control Method

As the “Volcker shock” is believed to have generated useful information on the effects of monetary policy, this paper develops a simple procedure to identify other unanticipated monetary contractions. The approach is applied to a panel data set spanning 162 countries (over the period 1970-2017), in which it identifies 147 large monetary contractions. The procedure selects episodes where a protracted period of loose monetary policy was suddenly followed by sizeable nominal interest rate increases. Focusing on contractions of significant size increases the signal-to-noise ratio, while they are unlikely to be accompanied by confounding “information effects” (markets interpreting a rate hike as the Central Bank being optimistic about the real side of the economy). A subsequent panel VAR analysis suggests that a 100-basis point rate hike reduces real GDP by 0.5 percent. This reduction in output seems to be persistent, pointing to a certain degree of hysteresis. The price level falls by 1.5 percent, indicating that the medium-/long-run impact of contractionary monetary shocks is not characterized by a neo-Fisherian response. Advanced economies appear to display more price stickiness than emerging/developing countries, as the former combine a more muted price response with a larger effect on output.
