Irish Economic Growth: MDD vs GDP Measurement Debate


  • The administration has persistently warned regarding the use of GDP as an accurate economic growth indicator due to the frequent inflation by multinational undertakings.
  • Modified Domestic Demand (MDD), the government’s chosen measure, is typically absent from the initial estimates.
  • Irish GDP, which continues to determine Ireland’s share of euro zone activity, is changeable and prone to significant alterations.
  • Within the first three quarters, Irish GDP experienced a 1.3% drop year-on-year while the MDD reflected an increase of 0.8%.

Understanding Economic Growth Indicators: GDP and MDD

For years, governmental authorities have consistently expressed reservations about using Gross Domestic Product (GDP) to gauge economic growth. Their concern lies in the systematic and frequent inflation by multinational corporations’ activities that could skew the perceived value. In contrast, the government’s preferred measure, Modified Domestic Demand (MDD), often do not feature in the preliminary estimations.

Role of GDP

Despite the reservations, GDP continues to provide a vital index in assessing Ireland’s economic contribution within the euro zone. However, early GDP estimates often undergo drastic revisions. Illustrating this volatility, data shows that Irish GDP declined by 1.3% on a year-to-year basis in the initial three quarters. Meanwhile, the MDD index displayed a growth of 0.8% – offering a contrasting economic picture.

The alterations and fluctuations seen in GDP and MDD measurements, and their implications on Ireland’s economic standing in the euro zone, reveal the complexities of economic assessments. These variations also signal potential impacts on international trading, especially in forex markets, influencing the performance of euro-denominated assets.
