Building the work of Chen, Lesmond, and Wei (2007), I attempt to follow their path to conduct empirical analysis using their econometric models . In the methodology part of my writing, I need to answer the questions below.

1. Explain and describe the methodology you are going to use.

2. Summarize the methodogies (econometric models-cross sectional, time series, panel data) used in the previous studies.

3. What are the pros and cons of them, particularly on what type of data each method best suitable? What specific methodology you think is best for your study after you discussed them. Personally, I simply think their models are feasible and I can understand most of them, and try to apply them to a different market. So I don't know how to explain why I choose their econometric models after comparing others.
