Since the 1990s, economists have looked for other significant determinants with a special focus on the quality of institutions to explain the heterogeneous trajectories of growth dynamics of countries around the world. In this regard, the current study provides the first empirical evidence in examining the relationship between institutional quality and economic growth in Jordan for the period of 1996-2017. The study uses an autoregressive distributed lag (ARDL) model as proposed by Pesaran et al. (2001). The empirical findings revealed that there is a co-integration (long-run co-movement) between economic growth and its determinants. Interestingly, there is a positive and significant relationship between institutional quality and economic growth in the long-run and shortrun. Moreover, the relationship between other explanatory variables such as investment, government size, inflation rate, and trade openness with economic growth is consistent with the standard economic theory. The policy implications from this study suggest that the Jordanian government should emphasize more on good institutional quality by improving all dimensions of institutional quality in sustaining their economic growth in the future.
