摘要
We identify five phases in the formation of M&A from the beginning until the newest developments when economic sanctions were imposed.The paper summarizes the results of empirical analysis of mergers and acquisitions(M&A)of Russian companies over the period 1995-2013.To capture the time series behaviour of M&A processes,we fit an autoregressive integrated moving average(ARIMA)model.We further analysed co-integration of M&A processes in Russia and US,China,and Germany.The results indicate German and Chinese M&A series have a long-term influence on Russian series,while no significant causal links were evidenced in the dataset between US and Russian series.
