This package provides a command to decompose the growth of an average quantity in a top percentile (in particular, the average wealth). This implements the accountiong framework defined in my paper Decomposing the Growth of Top Wealth Shares.

topdecompose varname  [,  top(dummyvariable) save(filename) replace clear Detail]

where

• varname is the variable to decompose
• top is a dummy variable indicating whether the observation belongs to the top percentile or not
• filename a filepath to save the output as a dataset. Alternatively, clear to clear the existing dataset with the output.
• Detail provides more intermediary quantities (e.g. average quantity in subsets of individuals)

The dataset needs to be declared as panel data before the command (using tsset or xtsset)

Installation
