Finnish Industry Investment ltd: an International Evaluation
The Finnish Industry Investment Ltd. (FII) is a government owned investment company, which started its operations in 1995.
Its core purpose is to stimulate the development of the Finnish venture capital industry particularly in those areas where market
failure has constrained the supply of equity finance to high potential, small and medium sized Finnish enterprises. FII invests in
young firms ‘indirectly’ via participating as a cornerstone investor in the new funds of venture capital firms, as well as investing
‘directly’ into Finnish firms.
In common with other European venture capital industries, the Finnish industry grew very rapidly between 1995−2000. However,
the Finnish market is still very small and under-developed by international standards, particularly, if the high knowledge
intensity of the Finnish economy is taken into consideration.
The limited availability of early stage (seed and start-up) venture capital to attractive young firms is the most urgent and persistent
failure in the Finnish venture capital market. The primary policy goal of FII has been to address this problem by helping to
set up, develop, and provide finance to venture capital funds investing in seed and start-up firms. However, FII has also has had
a requirement imposed by government to operate profitably. This has lead the organisation to seek later stage investments in
order to meet the profitability target. FII’s focus on profitability goal and its practice of investing on equal terms with private
investors has lead to a reduction in its effectiveness in resolving the market failure in early stage venture capital. FII’s reduced
impact has occurred at a time of worsening market conditions when the need for effective government intervention is highest.
The main conclusion of the evaluation is that FII should focus its operations more directly on resolving remaining market failures
in the supply of early stage venture capital. The evaluation also argues strongly that FII should concentrate on an indirect
operating mode whereby it finances, and incentivizes by asymmetric profit sharing, private investment professionals to set up
venture capital funds targeted at seed and startup stages. The same indirect approach should also continue to be used to resolve
market failures in the provision of regional venture capital. Additionally, FII has a valuable role in helping channel foreign
capital, including finance from EU, to Finnish early stage venture capital funds. Direct investments by FII to target companies
should be avoided as an operating mode.
Given the FII’s responsibility for addressing market failures, its performance measurement and governance systems should
fully reflect this primary goal. The evaluation also finds that FII’s communication and collaboration with other actors in the
Finnish innovation system should be improved. In addition to the need for improved coordination between the government
special financing agencies, there is also a need for more effective direction and coordination of policy at the highest executive
level, for example in ensuring the integration of enterprise policy and general financial policy to enable significant
improvements in the environment for growth-oriented entrepreneurship in Finland.Commissioned by

Assessment of welfare and brachycephalic obstructive airway syndrome signs in young, breeding age French Bulldogs and Pugs, using owner questionnaire, physical examination and walk tests
Brachycephalic obstructive airway syndrome (BOAS) is a major welfare problem in short-nosed breeds, such as the French Bulldog and Pug. In addition to respiratory difficulties, exercise intolerance and impaired recovery are major signs of BOAS. To select healthier breeding animals, exercise tolerance tests, such as the 1,000-m walk test, are already used in several countries for brachycephalic dogs, although evidence supporting their use is still scarce. The aims of this study were to assess the daily welfare of young, breeding-age French Bulldogs (n = 44) and Pugs (n = 51) using an owner questionnaire, and to evaluate 6-min walk test (6MWT) and 1,000-m walk test usability for differentiation between non-or mildly BOAS-affected dogs and more severely affected dogs. Only four out of 95 French Bulldog and Pug owners reported that the BOAS signs limited the daily activities of their dogs. However, according to the physical, examination-based veterinary BOAS grading, 31/95 of the dogs had moderate to severe BOAS signs. In both breeds, the more severely affected dogs performed both exercise tests more poorly than those with no or mild BOAS signs. The longer exercise, namely the 1,000-m test, seemed slightly better able at differentiating between affected dogs and less affected ones. The results of this study further support the use of exercise tests as an important part of the breeding selection in French Bulldogs and Pugs. By influencing the breed standards set by Kennel Clubs and by using breeding selection tools, the harmful impacts of brachycephaly can be diminished.Peer reviewe
A follow-up study of exercise test results and severity of brachycephalic obstructive airway syndrome signs in brachycephalic dogs
To promote successful breeding against brachycephalic obstructive airway syndrome (BOAS), it is important to assess how BOAS signs progress during young adulthood and how evaluation age and ageing affect the results of chosen breeding selection tools. The aims of this study were to assess how veterinary-assessed and owner-reported BOAS signs and exercise test results change when dogs age. Eight English Bulldogs, 25 French Bulldogs, and 31 Pugs that had undergone previous evaluation were re-examined 2- 3 years later. An owner questionnaire regarding BOAS signs, a veterinary assessment of BOAS severity, and exercise, ie walk tests were re-performed. In Pugs, both 6-min walking distance and 1,000-m time worsened and the initial evaluation age had a significant effect on the 1,000-m time. No significant changes were seen in the results of the French Bulldogs but a negative effect on the 1,000-m time was seen with weight gain. Exercise test statistics were not performed with regard to English Bulldogs due to low sample size. The veterinary-assessed BOAS severity class remained the same in the majority of dogs and the BOAS grade worsened mostly in those dogs that were initially evaluated at less than two years of age. Most owners reported no major changes in BOAS severity. BOAS grading and walk tests were easy to repeat and results remained relatively constant in dogs initially evaluated at over two years of age, supporting the use of these breeding selection tools. However, further, large-scale offspring studies are still needed.Peer reviewe
