Add literature context to Monetary Policy with Heterogeneous Agents

[Calbafa]

This PR adds Prior and Subsequent Literature sections to the ballpark item for
“Monetary Policy with Heterogeneous Agents” (Görnemann, Kuester, Nakajima, 2012).

It also improves clarity via minor typo corrections and adds Carlos Alba as a contributor.

MyST assembly feedback

Your PR adds valuable prior and subsequent literature to GKN Monetary Policy HA, but the MyST Assembly and PR assignment asks for a four-notebook MyST document that builds and renders. Right now the MyST build is not configured.

What you need to add

1. Create the four-notebook structure in models/We-Would-Like-In-Econ-ARK/GKNMonetaryPolicyHA/:

   • GKNMonetaryPolicyHA_intro.ipynb — paper metadata (Görnemann, Kuester, Nakajima 2012), original ballpark authors (Nino Kodua), your name as contributor
   • GKNMonetaryPolicyHA_prior-literature.ipynb — prior literature with MyST citations (you added this content to the main notebook; extract it into a dedicated notebook with {cite:t} / {cite:p} citations)
   • GKNMonetaryPolicyHA_summary.ipynb — copy your edited content from GKNMonetaryPolicyHA.ipynb here; add MyST citations, cross-reference links to the other notebooks
   • GKNMonetaryPolicyHA_subsequent-literature.ipynb — subsequent literature with MyST citations (extract the content you added into a dedicated notebook)

2. Organize bibliography files:

   • self.bib — the GKN (2012) paper
   • references.bib — prior literature (you have Gornemann_ballpark.bib; ensure prior refs are in references.bib)
   • subsequent-literature.bib — papers that cite GKN

3. Create myst.yml in the GKNMonetaryPolicyHA folder:

version: 1
project:
  title: "Monetary Policy with Heterogeneous Agents — Ballpark Entry"
  bibliography:
    - self.bib
    - references.bib
    - subsequent-literature.bib
  toc:
    - file: GKNMonetaryPolicyHA_intro.ipynb
    - file: GKNMonetaryPolicyHA_prior-literature.ipynb
    - file: GKNMonetaryPolicyHA_summary.ipynb
    - file: GKNMonetaryPolicyHA_subsequent-literature.ipynb
site:
  title: "Monetary Policy with Heterogeneous Agents — Ballpark Entry"

4. Verify the build from the GKNMonetaryPolicyHA folder:

myst build
