The statement "Transnational corporations accumulated disproportionate wealth in both waves" accurately analyzes the similarities between the two waves of globalization.
Transnational corporations have played a significant role in both the first wave of globalization (which roughly corresponds to the late 19th century) and the second wave (from the late 20th century onwards), often accumulating significant wealth and influencing global trade dynamics.
The other statements have varying degrees of accuracy and may not universally apply to both waves. For example, while globalization has contributed to poverty reduction in some less developed countries, it has also led to increased inequality and has not uniformly had a positive impact across all regions. Similarly, the nature of traded commodities has changed significantly over time, with different products dominating trade in each wave. Neocolonial economics can also be a complex and debatable aspect of globalization, not necessarily a defining similarity in both waves.
