We have considered the three key areas of macroeconomic policy – monetary policy, fiscal policy and supply-side policies.
In the longest essay questions on data response papers examiners often ask students to consider how effective these are when they are used to manage the economy. How can we judge whether the performance of the economy is improving as a result of them? In this session we will remember how to assess macroeconomic performance, think about some of the issues with measuring growth,
and focus on ways to evaluate the effectiveness of different policies

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
