What Are The Implications Of A Non-tariff Barrier, Specifically A Sanitary And Phytosanitary Measure, On The Welfare Effects Of A Small Open Economy That Is Heavily Reliant On Exports Of A Single Agricultural Commodity, When The Importing Country Has A Relatively Low Elasticity Of Demand For That Commodity?

The imposition of a sanitary and phytosanitary (SPS) measure by an importing country on a small open economy heavily reliant on a single agricultural export has several significant implications:

  1. Trade Impact: The SPS measure likely reduces exports from the small economy, as it may face stricter regulations that limit market access. This can lead to a decline in export revenue, affecting the specialized agricultural sector significantly.

  2. Welfare Effects:

    • Producer Surplus: The exporting country may experience a reduction in producer surplus due to decreased demand and lower prices, impacting incomes and employment in the agricultural sector.
    • Consumer Surplus in Importing Country: Consumers might face higher prices due to reduced supply, though the impact on quantity demanded may be limited due to low elasticity. If the SPS measure addresses genuine health concerns, there could be non-monetary benefits from improved safety.

  3. Terms of Trade: The small economy may face deteriorating terms of trade, as reduced demand for its exports weakens its bargaining power in international markets.

  4. Domestic Economic Impact: Excess production due to reduced exports could lower domestic prices, leading to economic losses. The broader economy might suffer from unemployment and reduced GDP, especially given the sector's specialization.

  5. Dynamic Effects: While short-term impacts are negative, the economy might diversify in the long term, though this requires resources and time, which may be challenging for a small, specialized economy.

  6. Political Economy Considerations: The government may face pressure to retaliate or comply with SPS measures, though options are limited due to the country's size and dependence on exports.

In conclusion, the SPS measure negatively impacts the small economy through reduced exports, lower welfare, and broader economic effects. The importing country may balance higher prices with potential health benefits, highlighting the complexity of SPS measures as both protective and precautionary tools.
