Content
• Financial performance of 35 European commercial airports (1990 – 2000)
• Evaluation of partial factor productivity (PFP), financial ratio (FRA) and data envelopment analysis (DEA)
• Comparison between public owned, privatised and partially privatised airports
Definitions of Ownership Structure
• Public Ownership: No involvement of private parties
• Partially Privatised: Requires a minimum private share >= 20% with regard to total equity or a lease or concession agreement with a similar risk profile
• Fully Privatised: Long-term private risk investment in terms of a substantial equity stake >= 75%, long-term lease or concession agreement, or a BOT franchise
Methodology
• Financial metrics emphasises profitability or return rates
• Productivity measures relationship between inputs and outputs
• An independent and a related t-test significance of results
Results of Independent t-Test
• Statistically significant or highly significant differences (95% and 99% confidence level respectively) between publicly owned and privatised airports for 20 out of 28 ratios
• No statistically significant difference: non-aeronautical share of total revenue, return on capital employed, EBITDA margin, return on equity, etc.
Results of Dependent t-Test
• Partially privatised: ADR, BRS, CPH, HAJ, NAP and VIE
• Fully privatised: BFS, CWL and EMA
• Assess financial performance before and after privatisation
• Statistically significant (95% confidence level) for 12 out of 28 ratios
Data Envelopment Analysis
• DEA scores are overall indices of (in)efficiency of the individual sample airports relative to each other
• Financial efficiency model was used• Consistent findings of the two t-tests are
confirmed by the results of total factor productivity in terms of DEA
• Indicates econmies of scale < 4 mill terminal passengers per annum
• Diseconomies of scale > 4 mill
Data Envelopment Analysis
• VRS: small and medium-sized sample airports operate under increasing returns to scale (IRS)
• VRS: airports and airport systems with traffic volumes in excess of > 3-4 mill terminal passengers operate under either constant (CRS) or decreasing returns to scale (DRS)
Data Envelopment Analysis
• Scale efficiency value of 1 no effect of scale size on productivity
• The lower the value of scale efficieny under 1, the more adverse the impact of scale size
• Airport sample trend of decreasing scale efficiency in parallel to increasing traffic volume
DEA Scores (Results)
• Higher efficiency in terms of DEA for partially and fully privatised airports
Conclusion
• DEA scores based on financial variables provide airport management with a useful tool to identify their relative position within the airport sector
• PFP and FRA useful for investor provide indications of the relative attractiveness of an airport as an potential investment
• Economically meaningful and statiscally significant differences between publicly owned and privatised airports for the vast majority of tested measures
