The Philippine Firm Level Panel Data
Much of my research employs a new dataset that matches the firm surveys and trade transactions records collected by the Philippine Statistics Authority (PSA) over the period 1991 – 2012. The firm survey data comprises of eight Annual Survey of Establishments (1997, 1998, 2001, 2003, 2005, 2008, 2009 and 2010) and three Census of Philippine Business and Industry (2000, 2006 and 2012). All the large firms with 200 or more employees (in some years, 100 or more) are surveyed, while the rest are sampled. The trade data is at the firm-product-destination level and consists of the universe of import and export data from 1991 till 2012. The Philippine data used has been gathered, merged and cleaned by me with help from the PSA. All the cleaning and merging is programmed in one STATA do-file that uses the background excel files of raw data in the process which is written by me. Therefore the raw data is never altered and all the steps made can be traced through the respective do-file. This is done in order to ensure consistency and traceability over time. For a more thorough and complete discription of the data see the research paper “An Empirical Overview of Philippine Trade” that can be found on the Research page.
