Costs of production are important, especially if you are an exporting country. It is critically important to know how your costs stack up against not just your neighbours across the field, but also how they measure up against other potential suppliers to the markets you have in your sights.Last week I attended a competitiveness workshop organised by Teagasc. It was part of a larger agriculture economics conference with contributions from all over the world. The ability to compete is key and the knowledge as to where we are strong or weak in world terms informs this. Are we fit to take on the world on a cost and market-access basis?
