This model is designed to analyze international and domestic trade by capturing the impacts of trade costs and policy changes within a general equilibrium framework. Additionally, it includes a local parameter to run simulations on productivity. The package provides functions for calibration, simulation, and analysis of the model.https://github.com/r-universe/noejn2/actions/runs/25654474699Thu, 24 Apr 2025 08:42:57 GMTgravityGE1.0.0successhttps://noejn2.r-universe.devhttps://github.com/cran/gravityGEnoejnava2@gmail.com (Noé J Nava)Tools for estimating censored Almost Ideal (AI) and Quadratic Almost Ideal (QUAI) demand systems using Maximum Likelihood Estimation (MLE). It includes functions for calculating demand share equations and the truncated log-likelihood function for a system of equations, incorporating demographic variables. The package is designed to handle censored data, where some observations may be zero due to non-purchase of certain goods. Package also contains a procedure to approximate demand elasticities numerically and estimate standard errors via Delta Method. It is particularly useful for applied researchers analyzing household consumption data.https://github.com/r-universe/noejn2/actions/runs/26018758520Tue, 18 Mar 2025 13:00:09 GMTcensoredAIDS1.0.0successhttps://noejn2.r-universe.devhttps://github.com/noejn2/censoredaids
