I solve the benchmark heterogenous-firm investment model

I solve the benchmark partial equilibrium firm investment model.

You can see the model and output here.

To run code in Julia REPL:

1. Download files
2. Type the path name into Julia REPL ";cd [pathname]\PEinvestment" into REPL
3. To load project, type "] activate ." into REPL
4. To load dependencies, type "] instantiate"
5. To precompile dependencies, type "] precompile"
6. To run code for PE model type "include("PEinvestment.jl")"
7. To run code for GE extension type "include("GEinvestment.jl")"
