A key theoretical contribution is the derivation of partial integro-differential equations (PIDEs) that characterize the fair delivery price of discretely sampled variance swaps within this framework.

Our findings show that family control is associated with a lower likelihood of engaging in M&amp;A transactions, reflecting a conservative strategic position. However, the structure of family ownership moderates this behavior: stronger voting rights increase the probability of acquisitions by reducing perceived threats to control, whereas higher cash flow rights amplify financial risk aversion, further discouraging acquisition activity. These effects are robust across variations in firm size, growth opportunities, dividend policies, and deal characteristics, such as industry-related and domestic deals. By showing how governance configurations shape the framing of M&amp;A strategic decisions, our study extends the mixed-gamble framework and highlights the internal signals family firms rely upon when navigating complex growth choices.

It is also found that STFPP has a pronounced effect in reducing carbon emissions through three mechanisms: strengthening carbon reduction policy intensity, promoting green technological innovation, and facilitating integration of digital and real economies. This investigation not only constructs a theoretical scaffold but also provides empirical evidence that elucidates the specific mechanisms by which STFPP can effectively decrease both carbon emissions and CMAC.
