- [KITE](https://julianhinz.com/data-code/kite/index.md) (Software): KITE (Kiel Institute Trade Policy Evaluation) is an open-source framework for quantitative trade-policy counterfactuals. It implements general-equilibrium trade models in the New Quantitative Trade Model tradition and solves them in changes with exact hat algebra: given a baseline and a policy scenario (tariffs, non-tariff measures, carbon taxes), it returns the counterfactual changes in welfare, production, and trade flows.
- [PLAID](https://julianhinz.com/data-code/plaid/index.md) (Dataset): An open database of product-level indicators for international trade, covering six indicators across ~5,400 HS 6-digit products and all seven HS revisions (1992--2022). Generated by an ensemble of frontier LLMs with built-in uncertainty quantification. Available at plaid.julianhinz.com as bulk CSV downloads, a JSON API, and an interactive explorer.
- [OSSIO](https://julianhinz.com/data-code/ossio/index.md) (Dataset): Open Source Software Input Output Tables — global input-output tables of open-source software flows between countries, constructed from developer locations and package dependencies across five programming languages and 15 countries. Published as a RADAR dataset by the Kiel Institute for the World Economy, July 2024, under CC BY 4.0.
- [glmhdfe](https://julianhinz.com/data-code/glmhdfe/index.md) (Software): R package that implements a fast estimation procedure of generalized linear models with high dimensional fixed effects. The package makes use of a convenient property of *some* combinations of error term distributions and link functions, where the fixed effects have — conditional on all other estimated parameters — an explicit solution.
- [Gravity Distances](https://julianhinz.com/data-code/gravity_distances/index.md) (Dataset): Gravity-consistent aggregate distances between countries and other geographical entities
- [gravity.distances](https://julianhinz.com/data-code/gravity.distances/index.md) (Software): R package that provides distances between geographic entities — such as countries, US states or Canadian provinces — that are consistent with the gravity equation in international economics.
- [mies.sty](https://julianhinz.com/data-code/mies.sty/index.md) (Software): A clean and typographic LaTeX article style inspired by Mies van der Rohe. Built for working papers and academic writing.
- [luhmann.sty](https://julianhinz.com/data-code/luhmann.sty/index.md) (Software): LaTeX Beamer style for academic presentations built on minimalist design.
