In recognition of gender inequities, more than 80 countries have applied a gender perspective to their budget process, initiatives referred to as gender‐responsive budgeting (GRB). Research on GRB initiatives has focused on whether they reduce gender inequities. However, if it is to have a lasting effect, GRB must reform the budget process and become integral to government administrative routines. We examine the experiences of several countries with GRB initiatives and identify the key factors explaining implementation success or failure. We find that these factors are similar to those that explain the success of earlier budget reforms focused on efficiency and effectiveness. While the equity objective of GRB differentiates it from other budget reforms, these factors provide the context for understanding GRB initiatives. Although gender parity is just one dimension of social equity, the success of GRB initiatives shows that governments can use their budgets to meet social equity objectives.
