change default initial interest rate to allow base solution #53

Closed jpycroft closed 1 year ago

jpycroft commented 2 years ago

I had been unable to solve the SS or TPI with the current default values (working with Windows OS and 4 processors).

@rickecon suggested trying a different starting interest rate: 0.03 --> 0.035 (line 1716 in oguk/oguk_default_parameters) and now my SS and TPI solve!

We suggest that the default "initial_guess_r_SS" be changed to 0.035.

This is failing because of a change to OpenFisca-UK - I'll fix it.

BTW, I got the steady-state solving under the initial guesses in #57

Closing this PR. I think the issues with starting values were resolved via PR #836 to OG-Core.
