Summary of "Simulation Results of AgriPolis about Diminishing Capital Subsidies and Restrictions"

Core Content

This paper presents the results of a simulation study using the AgriPoliS agent-based model to examine the effects of diminishing capital subsidies and credit restrictions on the structural development of four European agricultural regions: Altmark (Germany), Allgäu (Germany), Vysocina (Czech Republic), and Borsodi Mezoseg (Hungary). The study explores how changes in interest rates and credit availability influence farm investment behavior, production activities, and regional agricultural structure.

Main Findings

• Interest Rates and Investment Behavior: Higher interest rates have a less significant impact on declining production branches than on expanding ones. Farms tend to invest in the most profitable production branch, which may change under high interest rate conditions.

• Credit Restrictions and Investment Decisions: Farms under credit restrictions are more likely to choose smaller and cheaper investments over larger and more expensive ones. This leads to under-investment, which can result in income losses.

• Compensation for Income Losses: These income losses due to under-investment are partially offset by lower rental prices, which are influenced by the availability of capital and investment decisions.

• Regional Variations: The impact of interest rates and credit restrictions varies across regions, depending on their initial conditions and structural characteristics. For example:

  • Altmark and Vysocina have a higher share of rented land and hired labor, making them more sensitive to changes in capital availability.
  • Allgäu is dominated by family farms with high livestock density and low share of rented land, while Borsodi Mezoseg has a mixed production structure with a moderate share of rented land.

• Policy Implications: The study suggests that credit subsidies or market imperfections can have indirect effects on the type of dominant investment and, consequently, on the regional agricultural sector. It also implies that capital subsidies should be reconsidered in future EU agricultural policies, as the results indicate that EU agriculture is overcapitalized, and over-investment in fixed capital is common.

Key Information

Model Description

• AgriPoliS is a spatial-dynamic agent-based model that simulates agricultural structural change at the regional level while considering individual farm behavior.
• Farms are modeled as independent agents using mixed integer programming (MIP) to make investment and production decisions based on profit maximization.
• The model accounts for transport costs, investment costs, maintenance costs, and collateral requirements.
• Short-term credit is limited to 70% of land assets and 30% of equity share of assets, while long-term borrowing is not restricted if the farm’s liquidity is sufficient.

Scenarios Tested

• Interest rate variations: A 4% increase in interest rates was tested to assess its impact on production activities and investment decisions.
• Credit restriction variations: Scenarios with higher credit restrictions were simulated to evaluate the effect on investment size and type.

Investment Characteristics

• Investments are characterized by:
  • Type (e.g., hog house, cowshed, machinery)
  • Production capacity
  • Investment costs
  • Useful life
  • Maintenance costs (expressed as a percentage of total investment costs)
• Liquidity and equity are key variables that influence investment behavior and capital availability.

Economic Indicators

• Land price, livestock density, labour intensity, share of rented land, and debt ratio are used to model regional agricultural structures.
• The average farm size and specialization vary significantly between the regions:
  • Altmark and Vysocina are dominated by large-scale farms.
  • Allgäu and Borsodi Mezoseg have smaller farms with more diversified production systems.
• Biogas production is an important investment option in German regions (Altmark and Allgäu), influenced by the Renewable Energy Resources Act.

Conclusion

The study highlights that capital subsidies and credit market imperfections can influence investment behavior and regional agricultural development. Farms respond to higher interest rates and credit restrictions by reducing investment scale and focusing on more profitable branches, which can lead to structural changes in the agricultural sector. The results suggest that policy reforms should consider the indirect impacts of capital availability on investment patterns and regional agricultural development.

The impact of these changes is not uniform across regions, emphasizing the need for region-specific policy approaches. The AgriPoliS model provides a flexible framework to explore these dynamics, allowing for plausible simulations of investment behavior based on real-world data and model assumptions.
