Toolkit for counterfactuals based on a spatial equilibrium framework with heterogenous preferences by Ahlfeldt-Bald-Roth-Seidel (WIP)

Version 0.9, 2024-03

General instructions:

This toolkit allows for counterfactual evaluations of the effect of changes in labour productivity, quality of life, or housing productivity on employment, wage, and housing rent in a spatial general equilibrium framework with heterogeneous worker preferences. We use a toy version of the Quantitative Spatial Model in Ahlfeldt, Bald, Roth, Seidel (WIP). To establish the general equilibrium, the model clears the labour, housing, and goods market. For didactic purposes, the Stata ado implementation generates a graph that illustrates all combinations between the following endogenous variables that satisfy all equilibrium conditions: wage vs. employment, employment vs. rent, rent vs. wage. The rectangles in the graphs generated by the program are the only combinations of employment, wage and rent that satisfy all equilibrium conditions of the model. The program has been written using Stata 18. However, the code should also run on earlier versions.

A HTML (JavaScript) implementation of the toolkit (does not include the four quadrants) is available at toolkits.ahlfeldt.com.

Folders

Stata ado programme: To install the ado file in Stata, just type 'ssc install ABRS'. In case Stata cannot connect to the internet, you may also manually copy both files to your ado folder. The programme will be ready to use. For information on the syntax, type 'help ABRS'.
