Elderly labor supply, endogenous grandparental childcare, and fertility in an OLG model.

This repository contains the MATLAB scripts needed to replicate all figures from the article "Elderly labor supply, endogenous grandparental childcare, and fertility in an OLG model", by M. M. Baldi, R. Coppier, and E. Michetti. The goal is to replicate the results and figures published in the article, and each script serves a specific purpose in achieving this goal.

LIST OF FILES:
- figures_1_to_7.m: This script generates the figures presented in the article, specifically Figures 1 to 7.
- figures_8_and_9.m: This script generates Figures 8 and 9 from the article.
- figure_10.m: This script generates Figure 10 from the article.
- figure_11.m: This script generates Figure 11 from the article.
- figures_12_to_14.m: This script generates Figures 12 to 14 from the article.
- constraint_check_region_B.m: This script checks if the constraints are satisfied for region B of the model.
- dynamics.m: This script defines the dynamic evolution of the model, where it computes the paths of key variables over time.
- feasibility_region_B.m: This code solves the constrained nonlinear programming problem (36)–(51) from the article, providing a feasible solution along with its approximation. A posteriori, it also verifies that the obtained feasible solution actually satisfies the original constraints.
- initial_check.m: This script performs an initial check on the parameter values to ensure they meet the condition lambda - beta*delta > 0.
- verify_eq_B.m: This script calculates the equilibrium values for the case B.
- verify_eq_D.m: This script calculates the equilibrium values for the case D.
- README.pdf: This file provides detailed instructions for replicating the figures in the article.
