Dear Tanveer,

Your question is not an innocent one. Being from the WTO, you know all that can be done quantitatively in CGE models already. It must mean that some of the MA, DA, and Rules you talk about are not measurable because they are say cultural, command, or non-democratically driven. I can only suggest that you use some cultural index, and for democratic measures, you are probably aware of these measures: 

Polity IV, Freedom House (FH), and Democracy and Development (DD).(see Dahl et al., 2003, p. 527)

For instance, one can compute a democratic variable for Polity IV based on the following indices: (Marshall and Jaggers, 2002, p. 24)

·         Competitiveness of executive recruitment (XRCOMP, which includes four steps or degrees).

·         Competitiveness of participation (PARCOMP, with six steps),

·         Executive constraints (XCONST, containing seven steps),

·         Openness of executive recruitment (XROPEN, which includes five steps),

·         Regulation of participation (PARR EG, based on five steps).

Tarveen,

One problem involves the validity and reliability of data as services cut such a wide swathe. The WTO relies on member countries to provide official statistics, and for various reasons, these data may be misleading, if not downright wrong. In our research on Chinese subsidies, we found utilities such as electricity highly subsidized, for example; yet, these subsidies do not emerge in service calculations. Statistics on government procurement are also murky. 

China presents an extreme case because of the amount of trade in which it engages, but measurement problems seep through all emerging markets, affecting policy and strategy.  

On food security, governance issues, and lack of sufficient data on who owns whom becomes an issue.  See my testimony before the US Senate on the Smithfield acquisition for more details.

More information on the data problems we covered are in our book, "Subsidies to Chinese Industry: State Capitalism, Business Strategy and Trade Policy" Oxford University Press.  You may access a description through the link to my profile below.

Hope this helps.

Best, 

Usha
