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

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.
