The Wikipedia article for "Corruption in the Philippines" is considerably short for a country ranked 101th place out of 176 countries in the 2016 Corruption Perception Index. In this sense, there are aspects of the article that can be furthered expanded on in: manifestations of corruption in the Philippines, citations, as well as the focus of the Wikipedia article, which emphasizes the decline rather than the context of corruption of the Philippines in the decades..
The introduction mentions that the Philippines experiences corruption in the form of "graft, bribery, embezzlement, backdoor deals, nepotism, and patronage" and yet it didn't go into detail of how graft, bribery, embezzlement, backdoor deals, and patronage manifests in the Philippines - save for nepotism which is furthered detailed in the latter half of the Wikipedia page as the "Padrino System". For instance, after a some time researching corruption in the Philippines, I found a report written by The Office of the Ombudsman, as office which is specifically designated to investigate government officials for charges for alleged graft and corruption cases. In their 2013 Corruption Survey Report, they found that from 2010 to 2013, bribery had shifted from being demand-driven to increasingly becoming initiated by government officials (i.e supply driven). With this research on bribery in the Philippines, there is reason to believe that certain aspects of corruption in the Philippines such as: graft, bribery, embezzlement, backdoor deals, and patronage can be further extrapolated on.
Secondly, even though for the most part the citations worked (four out of five of the citations work), I found that the first link was broken for "Jurado, Emil (March 12, 2010). "The fourth most corrupt nation". Manila Standard Today. Retrieved August 21, 2010."
I also find it interesting that the "Decline" in the Philippines (for corruption) is considered the most relevant topic in corruption in the Philippines, as it is the first sub heading, seeing as after some research, I found a couple corruption scandals that were not mentioned in the Wikipedia article. For example, the 2000 resignation from office by President Joseph Estrada, after public outrage over allegation for corruption, impeachment court proceedings - which eventually led to President Estrada's conviction for graft and corruption and consequently life imprisonment. Furthermore, a similar paragraph can be made for the Philippine dictator, Ferdinand Marcos which was shown from a 1987 study found that 25 percent of the national budget was lost to graft and corruption.
Despite the international recognition for the Philippines being a corrupt country from the Corruption Perception Index and Global Financial Integrity, there lacks a discussion on the Talk page of the Wikipedia article. The article was written that the Wikiproject, "Tambayan Philippines," which is "a collaborative effort to improve the coverage of topics related to the Philippines on Wikipedia." With more collaboration and discussion, the Wikipedia article on "Corruption in the Philippines" can be furthered and detail of corruption in the Philippines can be definitely expanded upon.
