You are probably already familiar with the piece but Benedict Anderson's piece "Cacique Democracy in the Philippines: Origins and Dreams", New Left Review I/169, May-June 1988 was probably one of the first pieces to highlight the role of elites in the politics of the Philippines.
There is research work done by Claudia Derichs, Andrea Fleschenberg et al. om 'Dynasties in Asia, maybe this does include the Philippines, too: https://www.uni-marburg.de/fb03/politikwissenschaft/institut/lehrende/derichs/publications2014neu.pdf

Dynasties and Female Leadership in Asia
Project sponsored by the German Science Foundation (DFG), April 2003-May 2005.
Project directors: Dr. Claudia Derichs (Duisburg) and Prof. Mark R. Thompson (Erlangen-Nürnberg)
Summary:
It is striking how many governments or opposition movements in Northeast, Southeast, and South Asia have been, or are led by women given the fact that these countries are widely considered patriarchal and paternalistic in character. Our study encompasses fourteen women leaders from ten countries (Bangladesh: Sheikh Hasina Wajed and Begum Khaleda Zia; Burma: Aung San Suu Kyi; India: Sonia Gandhi*; Indonesia: Megawati Sukarnoputri; Japan: Tanaka Makiko; Malaysia: Wan Azizah Wan Ismail; Pakistan: Benazir Bhutto; Philippines: Corazon C. Aquino and Gloria Macapagal-Arroyo; Sri Lanka: Chandrika Kumaratunga*; South Korea: Park Geun Hye). There is no doubt that the rise of female leaders is linked to their being members of prominent families: they are all the daughters, wives, or widows or former government heads or leading oppositionists. These women share dynastic origins and "inherited" political leadership. As a general phenomenon political dynasties are not unusual. What is less usual is women being the beneficiaries of their family's political inheritance. It is not just a "shortage" of men that leads women to be selected as successors within the family, but also their ability to symbolize a non-partisan alternatives to corrupt (male) leadership. In addition to the question "why women leaders" this project will consider what difference female leadership makes. Finally, we will examine what the results of this study can add to discussions of the concepts of gender, development, and democratization. ..."
you'll find at least one article on the Philippines.
You might find these articles useful as regards to contemporary assessments of political dynasties in the Post-Marcos era.

This is a timely topic as the Philippine Congress is currently debating the passage of an anti-political dynasty bill, which will in all likelihood fail.
If you have been following the news in Manila newspapers over the past 3 years, you’ve been hearing about the powerful Angara dynasty, which have ruled much of northern Aurora Province (Philippines) for most of the past 60 years. They have recently formed a huge wealthy multinational corporation called APECO (Aurora Pacific Economic Zone) that is claiming 12 thousand hectares of forest lands where the Casiguran Agta Negritos have lived for many hundreds of years. APECO is attempting to displace the Agta and hundreds of Tagalog farmers from the area, where my wife and I have lived for most of the past half-century.
For background, read our report of this in the online journal LANGSCAPE 2(12):54-63, titled “Land Rights and Inclusive Development: The Struggle of Marginalized Peoples against APECO,” by Jerome Patrick Cruz, et al., published Nov 18, 2013. It is available free online at www.terralingua.org/lit/langscape.
