Corporate finance literature suggests that diverse boards are a part of good corporate governance practice. However, it is not clear how diverse board characteristics might affect innovation and innovation search strategies. Utilising the data from 25 banks listed in the UAE stock exchanges, this study evaluates the impact of boardroom diversity on firm innovativeness both before and after the drop in the oil prices. The results show that although gender and education do not significantly affect innovativeness of banks, having more experienced and independent board members enhances the innovation. The effect of experienced board members on innovation is more pronounced during the oil price drop period, whereas the effect of independent board members decreases after the drop in the oil prices.
