Lithium has an increasingly strategic role as clean technologies emerge, affecting the strategies of oil and gas companies in response to energy trends. This paper contributes to this literature, studying the dynamics of lithium industry and mergers and acquisitions in the U.S. oil and gas industry in time-frequency domain. We use methodologies based on Continuous Wavelet Transform (CWT) and Vector AutoRegressive Models (VAR), and the results indicate that both time series are correlated in the long term, where M&A U.S. oil and gas industry dependence on lithium industry has increased, starting in the early 2014 until the end of the sample. Evidence of causality is not found between both time seriesengAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Lithium IndustryOil and gas industryMergers and acquisitionsWavelet analysisjournal articleopen access10.1080/15567249.2018.1541947
