Summary of Ukraine Gas Pricing Policy: Distributional Consequences of Tariff Increases

Core Content

This paper examines the economic and distributional consequences of increasing gas and heating tariffs in Ukraine, with a focus on how such reforms can be implemented without causing significant welfare losses, especially among lower-income households.

Ukraine's current gas pricing policy heavily subsidizes household gas and heating, which has led to significant financial strain on the government, energy over-consumption, and reduced incentives for domestic production and infrastructure investment. The policy is politically sensitive, and tariff increases have been delayed, leading to long-term inefficiencies and dependency on Russian gas imports.

The paper argues that a combination of tariff increases and targeted social support can improve economic efficiency and reduce the burden on government finances, while still protecting the welfare of the poorest segments of the population.

Main Views

• Current Policy Issues:

  • Implicit subsidies to households through under-priced gas and heating tariffs have been a long-standing policy.
  • These subsidies are costly, amounting to nearly 5% of GDP annually.
  • They disproportionately benefit wealthier households, who consume more and have greater access to resources to mitigate the effects of higher prices.
  • The policy is unaffordable, unsustainable, and undermines domestic production and energy efficiency.

• Economic Consequences:

  • Underinvestment in domestic production and outdated infrastructure has increased Ukraine's reliance on Russian gas.
  • Gas and heating tariffs are significantly below import prices, leading to losses for Naftogaz (NG) and heating utilities.
  • Government finances are strained to cover these losses, often through debt financing, tax offsets, and direct subsidies.

• Distributional Impacts:

  • A 20% tariff increase leads to a 5% reduction in gas consumption and a 3% reduction in heating consumption, with effects increasing with income level.
  • While wealthier households experience larger absolute losses in consumer surplus, lower-income households face a greater proportional welfare loss.
  • Social assistance programs can offset these losses for poorer households, but they are currently inefficient and unevenly distributed.

• Policy Recommendations:

  • Gradual but immediate tariff increases are necessary for long-term economic efficiency.
  • Social assistance reforms should target the most vulnerable and be means-tested to ensure that the poorest are protected.
  • Increasing building-level metering improves billing transparency and encourages households to accept tariff increases.
  • Tariff reform combined with targeted support can free up government resources for growth-enhancing investments in infrastructure, energy exploration, and social programs.

Key Information

Household Demand and Elasticity

• Short-run Inelasticity:

  • Gas and heating demand are inelastic in the short run, with a 10% tariff increase leading to a 1.65–1.82% drop in heating consumption and a 2.63–2.83% drop in gas consumption.
  • The price elasticity of the wealthiest quintile is significantly higher than that of the poorest, with heating and gas price elasticities being 10% and 8% higher, respectively.

• Income and Consumption Relationship:

  • A 10% increase in household income leads to a 1.1% increase in heating consumption and a 1.7% increase in gas consumption.
  • Larger households and more people in a home lead to higher gas and heating demand.
  • Apartment buildings tend to have higher heating demand compared to individual homes.

Financial and Social Implications

• NG Financials (2011):

  • Total revenues: 114 billion UAH (8.7% of GDP).
  • Total expenditures: 135 billion UAH (10.3% of GDP).
  • Cash balance: -21 billion UAH (-1.6% of GDP).
  • Gas sales: 86 billion UAH (6.6% of GDP).
  • Gas imports: 74 billion UAH (5.6% of GDP).
  • Government subsidies and support for households and heating utilities: 17 billion UAH (1.3% of GDP).

• Social Assistance:

  • Social assistance for gas and heating is a small portion of the total budget, at 0.2% of GDP.
  • Benefits are distributed unevenly, with 30% going to the wealthiest quintile and only 20% to the poorest.
  • About 85% of people below the poverty line do not receive any social assistance for gas and heating.
  • Social assistance is not very effective at reducing poverty, with only 5–12 cents per dollar spent contributing to poverty reduction.

Reform Strategy

• Tariff Increases:

  • Should be gradual but consistent, with a clear schedule for cost recovery.
  • Will encourage energy efficiency and reduce over-consumption.
  • May lead to increased demand for energy-saving materials and renovations.

• Social Assistance Reform:

  • Should be means-tested to ensure that the poorest are supported.
  • Explicit subsidies should be provided to households where utility expenses exceed 15% of income.
  • Cash transfers can compensate for the loss in consumer surplus due to higher tariffs.
  • This approach allows for greater efficiency and better targeting of resources.

• Infrastructure Investment:

  • Annual investments of US$1.5 billion in unexplored gas reserves could reduce Russian gas imports by half within a decade.
  • Upgrading domestic gas and heating infrastructure is essential for long-term efficiency and self-sufficiency.

Conclusion

• The paper concludes that a shift towards marginal cost pricing for gas and heating, combined with targeted social assistance, is necessary to address the inefficiencies of the current subsidy regime.
• This approach can reduce government expenditure, promote energy efficiency, and support economic growth without imposing large welfare costs on the poor.
• The long-term benefits of such reforms, including reduced import dependence and improved infrastructure, are expected to outweigh the short-term costs, especially when social assistance is reformed to be more effective and equitable.
