The current study is motivated by the overall lackluster performance of IMF p rogrammes in recip ient countries in terms of econo mic growth consequences, and tries to explore the relevance of institutional determinants (that have a positively significant role in improving institutional quality in IMF programme countries, in the first place) in enhancing real economic growth in IM F programme countries; as otherwise highlighted by New Institutional Econo mics literature for countries generally. Moreover, the study also investigates the impact of these determinants through the channel of macroeconomic stability. Based on a time period of 1980-2010 (co inciding with a durat ion of increasing nu mber of IMF p rogrammes), the results mainly validate that institutional determinants overall play a positive role in reducing macroeconomic instability, and through it, and also independently, enhance real economic growth.
