Final answer:
The question focuses on the impact of learning, core competencies, and economies of scale on worker productivity in intra-industry trade, and how these play a part in evolving comparative advantages and international trade dynamics.
Step-by-step explanation:
The question presented pertains to intra-industry trade and the various strategies and dynamics in multinational enterprises and their production. It delves into concepts such as learning effect, core competence, and economies of scale, highlighting the significance of locations and how firms and countries must be adaptable as comparative advantages can evolve over time. Such adaptability may come from the acquisition of new skills, innovation, and the strategic positioning of various segments of the value chain. International trade is also influenced by these factors and reducing barriers to trade, like tariffs, can yield numerous benefits including cost-reduction and improved efficiencies.
Two benefits of reducing barriers to international trade include allowing countries to focus on producing goods they make most efficiently, leading to profitable industries and higher-quality, lower-cost goods for consumers. Additionally, economies of scale can be realized as firms spread fixed costs over larger volumes, leading to lower per-unit costs.
