Summary of the Selected Issues Paper on the Republic of Poland

Core Content

This document provides an in-depth analysis of inflation dynamics, balance sheet effects from low inflation, and the role of structural transformation in raising productivity growth in the Republic of Poland. The paper is part of the International Monetary Fund (IMF) staff team's background documentation for periodic consultations with Poland and is based on data available up to June 22, 2015.

A. Forecasting Inflation in Poland

Main Points

• Inflation Trends: Poland's inflation has remained below the target band for about two years, with external shocks contributing to downward pressure, especially in 2014. The inflation rate dropped from 4.3% in June 2012 to -1.6% in February 2015, reaching a historic low.
• Output Gap and Inflation: The traditional link between headline CPI and the output gap has weakened, indicating that factors other than domestic slack are influencing inflation dynamics.
• Core Inflation: Core inflation has also remained subdued, despite a narrowing output gap and accelerating domestic demand and wages. This suggests the presence of indirect and second-round effects.
• Indirect and Second-Round Effects: These effects are significant in explaining the persistence of low inflation. They include impacts from falling energy prices and low inflation in the euro area, which spill over into domestic CPI through input-output linkages and expectations.

Key Drivers of Inflation

• Weak Food and Energy Prices: Subdued world food prices, mild winter in Poland, and a Russian import ban contributed to weak food inflation.
• Low Energy Price Inflation: Declines in energy prices, including oil and coal, have been a drag on headline CPI.
• Imported Inflation: Low inflation in the euro area, particularly Germany, has had a spillover effect on Polish inflation.
• Exchange Rate Stability: A stable euro/zloty exchange rate has limited the pass-through of imported inflation to domestic prices.

Forecasting Models

• Short-Term Forecasting System (STFS): Uses six models to generate quarterly inflation forecasts. Forecasts vary significantly depending on the model, with the DFM model predicting -0.7% and the BRIDGE model predicting 1.1% for 2015Q2.
• Augmented Phillips Curve: Incorporates inflation expectations, real activity, and the nominal effective exchange rate. It accounts for both adaptive and forward-looking expectations, as well as imported inflation and supply shocks.
• Disaggregate Model: Decomposes inflation into an inertial component and indirect/second-round effects. It allows for the analysis of how shocks to specific CPI components affect overall inflation, considering interactions and pass-through mechanisms.

Outlook and Risks

• Persistent Low Inflation: The models suggest that inflation will remain low in the absence of further monetary policy action.
• Inflation Expectations: Declining inflation expectations may lead to downward revisions in wage growth, further suppressing inflation.
• Second-Round Effects: These effects are substantial and persistent, even after the initial shock. They contribute significantly to the overall inflation path, particularly in the medium term.

B. Balance Sheet Effects from Low Inflation

Main Points

• Impact on Households: Low inflation has reduced real household income and increased debt burdens, especially for those with fixed-rate mortgages and loans.
• Nonfinancial Corporations: Weak inflation has led to lower nominal profits and increased real debt, affecting corporate balance sheets and credit risk.
• Banks: Banks have experienced lower interest margins due to low inflation, which has compressed their profitability.
• General Government: Low inflation has reduced inflation-linked liabilities, but it has also led to lower tax revenues and increased real debt.

Key Findings

• Overall Impact: The protracted period of low inflation has had a broad and lasting impact on the balance sheets of all sectors.
• Exchange Rate: A stable exchange rate has limited the pass-through of imported inflation, reducing its effect on domestic prices.
• Policy Implications: Policymakers need to be cautious about the potential for second-round effects to further suppress inflation and affect economic stability.

C. Raising Productivity Growth in Poland: The Role of Structural Transformation

Main Points

• Labor Market Trends: Poland has experienced a decline in unemployment and relatively strong nominal wage growth, which may signal a tightening labor market.
• Productivity Growth: Aggregate labor productivity growth has been influenced by structural transformation, with a shift in employment from low-productivity sectors to high-productivity ones.
• Decomposition of Productivity Growth: Using sector-level data, the paper shows that productivity growth is driven by both structural shifts and within-sector efficiency improvements.
• Factors Facilitating Structural Transformation: These include technological progress, openness to trade, and institutional reforms that enhance competitiveness and innovation.

Policy Implications

• Structural Reforms: Continued structural reforms are essential to sustain productivity growth and support long-term economic performance.
• Within-Sector Productivity: Improvements in productivity within existing sectors are also important, especially as structural transformation slows.

Key Information

• Inflation Target: Poland's inflation target is 2.5%, but inflation has remained below this for two years.
• Models Used: STFS, augmented Phillips curve, and a disaggregate model with indirect and second-round effects.
• Data Sources: Includes data from the National Bank of Poland (NBP), European Central Bank (ECB), and other macroeconomic indicators.
• Time Frame: Analysis covers the period from 2004 to 2015, with a focus on recent developments up to 2015.

Conclusion

• Inflation Dynamics: Low inflation in Poland is influenced by both direct and indirect factors, including weak energy prices and low inflation in the euro area.
• Policy Challenges: Policymakers face the challenge of balancing monetary easing with the need to anchor inflation expectations and mitigate second-round effects.
• Structural Transformation: This is a key driver of productivity growth, but its pace has slowed, requiring continued reform efforts to maintain momentum.
