A new theoretical model of government backed venture capital funding

Government involvement in the venture capital (VC) market has become an important catalyst of the entrepreneurial ecosystem of young and innovative firms. There is an extensive literature describing the VC model, but the models of its government backed variants are not comprehensively discussed. The article focuses on the model of purely government backed venture capital (GVC) and hybrid venture capital (HGVC). The conclusion of this article is that, by the logic of their models, GVCs are destined to underperform than private VCs. Many articles see HGVCs as a step forward compared to GVCs, as they involve private participants. The novelty of the current article lies in bringing out the drawbacks deriving from the system of hybrid venture capital funding by creating a complex theoretical framework of the HGVC model. We show that due to the crowding in of private participants, this scheme creates a two-goal system where the private profit maximising interests conflict with the economic policy goals. The complex system of HGVC is exposed to increased moral hazard issues that might lead to higher distortions than GVC. The conclusions are especially relevant in the case of developing industries.


INTRODUCTION
Young and innovative small firms play an essential role in modern economies. There are many studies emphasising their importance in bringing radical innovations to market (Abernathy -Utterback 1978;Scherer -Ross 1990;Kirchhoff 1993;Bower -Christensen 1995;Baumol 2002;Roszko-W ojtowicz -Białek 2018). Moreover, such enterprises also have a spurring effect on employment and economic growth. Regardless of their roles in economies, for a variety of reasons, such companies face difficulties in obtaining the necessary resources for growth due to market failures, such as information asymmetries and externalities, combined with the problems of high uncertainty and the lack of collateral (Gompers 1995;Philpott 1994;Mason -Harrison 1997;Hall 2002;Cressy 2002;Becsky-Nagy 2016). The institution of venture capital (VC) is supposed to provide a solution for the funding problems of these companies. In well-developed entrepreneurial economies, VC plays a major role in the funding of young and innovative enterprises; therefore, it is an important element of the innovation systems (Kenney 2011). The positive effects of enterprises that are in the scope of VC provide a strong foundation for public support, especially with regards to the market failures connected to them. As a result of information asymmetries, adverse selection (Akerlof 1970) and moral hazard issues (Jensen -Meckling 1976) evolve. Additionally, the positive externalities of their innovation also result in sub-optimal levels of investment.
Government agendas aiming at the development of VC markets worked under the presumption that the inefficiencies of the supply side lag behind the relative underdevelopment of the market; therefore, the public sector tried to support private investors through direct interventions and filled in for them in their absence by providing a VC type funding.
The global financial crisis in 2008 and the increasing funding problems of small-and medium-size enterprises (SMEs), more specifically the young and innovative firms led to a more extensive involvement in the VC markets of Europe. Prior the crisis the amount of capital allocated into the VC industry in Europe by government agencies was relatively low (less than 10% of the total capital raised), but in the past decade the proportion of incremental capital raised by government agencies moved between 20% and 30% on average (Invest Europe 2016, 2019. However, the European market is not uniform in this sense. In different regions the role of government funding varies significantly. In the UKwhere the VC industry shows a great resemblance to the most developed US VC marketgovernment funding has a lesser role relatively, but in the funding of early stages even in the UK public funds had a prominent role after the recession (Pierrakis 2010). On the other hand, the developing industries of CEE rely mostly on state subsidy.
The current article focuses on the questions regarding the design of government VC agendas and aims to create a new model of government VC. The article discusses the theoretical framework of different forms of government direct involvement; pure government venture capital funds (GVCs) and hybrid venture capital funds (HGVCs). While in theory the primary goal of both types is to alleviate the funding problems of young and innovative enterprises and, in this sense, they are similar to market-backed private venture capital (PVC), the underlying incentives are different and theyby their very naturelead to different results on the market. The questions regarding the efficiency of government interventions will be discussed in the context of the theoretical models of GVCs and HGVCs.

LITERATURE REVIEW
Although there are many types of government interventions in the venture capital market, there are two underlying assumptions that are common in these agendas; first, because of market failures, there is insufficient funding for new, innovative companies and second, governments are able to mend these failures either by selecting and financing viable enterprises or by influencing the market in order to spur these activities (Lerner 2002).
If the government program focuses on the selection and funding of the enterprises, then we are talking about the direct involvement of government, where the public agencies are imitating the PVCs and replacing them. On the other hand, when the government programs are influencing the ecosystem of new, innovative firms and the private participants in order to appear on the VC market, then governments exercise their indirect role in developing an industry.
Direct interventions on the VC market or the active roles of government denote the VC-oriented use of government funds when government provides capital for VC funds and manages them or influences their management. The foundation of these programs is that, as a result of market failures, funding gaps evolve, and viable enterprises are not able to obtain capital (Harding 2002).
HGVCs appeared in the field of direct interventions in addition to GVCs. HGVCs represent the cooperation of market and government backed participants, where the capital is provided at least partially by the public sector. Although its use is regulated by government, the actual management of funds is the responsibility of private participants. By its logic, HGVCs are built on the approaches of an active (by providing capital) and a passive role (incentivising market participants to appear on the VC market) of government.
Built on the idea that the cooperation with private participants increases the effectiveness of government backed VC agendas, several HGVC type programs were launched in Israel, New Zealand, Canada, Australia, Finland, the UK, China and with the promotion of the European Regional Development Fund (ERDF) in the developing VC industries of the Southern and the CEE countries.
VC influences the economy indirectly through the performance of the invested enterprises. Table 1 summarises the literature focusing on the performance of VC backed firms.
The vitalization of VC markets through direct state (or government) interventions is far from being unprecedented. Becker -Hellmann (2005) examined the first German VC fund created in 1975 with the support and involvement of government. The authors point out that this initiation failed ultimately as the government backed fund was unable to imitate the special value creating mechanisms of PVC. Moreover, at the same time, the entrepreneurial environment was not fitting for professional VCs. Engel -Keilbach (2007) identified the reasons for the latter boom of the German VC market in 1995-2000 in the improvement of stock exchange for smaller firms, the appearance of technology-oriented new firms and the establishment of a coinvestment hybrid fund. They showed that in Germany, the VC enterprises had higher growth rates and increased patent activity, although patents were applied before the investments were made. Therefore, they concluded that VC assisted the companies in commercialisation rather than in R&D. By examining the Belgian market, Manigart et al. (2002) found that the survival rate of the VC backed companies was lower than for the non-VC backed companies, especially if the VC was backed by the government. Also based on evidence from the Belgian market, Alperovych et al. (2015) found that the government VC backed firms achieved lower productivity compared to their PVC peerseven compared to the non-VC backed firms.

The studies mentioned above focus on the country-specific case studies. In addition to these studies, more research was carried out examining the effects of the government backed VC based on international evidence. They give a comprehensive analysis of government VC and they do not make specific conclusions regarding the unique aspects of regulation. Rather, they make general conclusions about VC. Bertoni -Tykova (2012) investigated 7 European countries focusing on the biotech and healthcare industries in 1994-2004. Based on their results, the government backed VCs fell behind PVCs and as single investors, they were not able to improve the performance of the invested firms. Government backed investors were able to provide value in syndicated investments with PVCs as the lead investors. Brander et al. (2015) investigated the effects of government backed VC funds by analysing 20,446 investments made in 2000-2008 in 25 countries. They measured the success of investment on the basis of exits. According to their results, the government backed funds were able to improve exit prospects as minority owners if they made their investments together with PVCs. However, as lead investors, they were less efficient than their private peers. They had the same conclusions on the Canadian market. One way this supports the notion that the government backed VC is not able to imitate the value enhancing mechanisms of PVCs and its services are limited to the provision of capital (Schilder 2006). Alternatively, Brander et al. (2015) explained these results with the economic policy aspects of government backed funds where investors broaden the scope of possible investment targets and provide capital even for those enterprises that could not obtain it based on purely market rationales. These results are also consistent with the findings of Gompers (1995), who stated that in the case of government investments, profit maximization is biased, as governments have economic policy functions, as well.
By using the VICO database covering the firms of 7 countries, Grilli -Murtinu (2014) examined the growth of revenues and employment. They had similar results to Brander et al. (2015); as lead investors government backed funds could not enhance the growth of the invested companies, while coupled with independent funds they were able to improve it. Luukkonen et al. (2013) confirmed via questionnaire that government backed funds lag behind their independent peers in terms of non-financial value added services, especially in strategic support, management assistance, enhancing growth and preparing exit.
International evidence suggests that GVC spurs firm performance in syndicated investment in cooperation with independent PVCs (Bertoni -Tykova 2012;Brander et al. 2015;Cumming et al. 2017;Grilli -Murtinu 2014). With PVC as a lead investor and GVC as a minority investor the advantages of both forms can prevail. The special expertise and the non-financial value added services of PVC can support the firm's performance, while the financial support of GVC can mend problems deriving from low capital. Especially in the European markets the additional capital provided by the GVC might have higher marginal contribution as the average investment size is lesser compared to the US investments. Therefore, syndicated investments with GVC as a minority investor might benefit from the positive synergies of different VC schemes.

Effects of hybrid venture capital funds on invested enterprises
In most cases, the studies mentioned above did not discuss the form of government funding; a fund is considered to be government backed if the government takes part directly in its operation either by providing capital or management assistance. Studies making a distinction between GVCs and HGVCs are relatively rare.
A research investigating the effects of hybrid funds in the UK concluded that these funds had modest but positive effect on the segment of young and innovative firms (Nightingale 2009). According to this research, both demand and supply side inefficiencies led to the modest results of these funds. Although there were irrational criteria in regulation, the demand side was not prepared to absorb this capital efficiently. More studies emphasize the demand side inefficiencies as the main reason for the relative underdevelopment of the European VC market (Becker -Hellmann 2005;Engel -Keilbach 2007;Veugelers 2011;Murray et al. 2012).
The findings of Cumming -Johan (2016) are unique in the empirical studies examining the effects of government VC backed firms, as on the Australian market HGVCs were able to outperform their PVC peers in terms of spurring employment and innovation. Brander et al. (2015) provided a detailed discussion about the effects of different type of government funds. Their general result was that the government backed VCs underperformed than their PVC peers, but they found evidence that HGVCs improved the exit prospects of firms compared to the pure GVCs. The relevance of HGVCs, furthermore, is that their appearance increased the amount of capital invested into PVCs, so they were able to attract further participants to the VC market. This suggests that HGVCs have a crowd in rather than a crowd out effect.
A research investigating the effects of HGVCs and GVCs of the Hungarian investments made in 2010-2016 found evidence that the hybrid venture capital backed firms generated lower growth and employment than their purely government backed VC financed peers. Both forms' firms showed meagre activity in the field of innovation (Fazekas -Becsky-Nagy 2018). The authors concluded that the inefficient design of the Hungarian HGVC scheme led to high moral hazards that hindered the efficient use of public funds.

THE THEORETICAL MODEL OF VENTURE CAPITAL AGENDAS
3.1. The theoretical model of purely government backed venture capital agendas The systematic approach of the PVC model is in the focus of many studies (Gompers -Lerner 1998;Lerner 2003;Metrick 2007;Da Rin et al. 2011). In contrast, as the role of the government backed VC is increasing especially in the developing industries, the model of government backed VC is becoming increasingly important. Differences in the PVC's and GVC's models run much deeper than the source of capital. Table 2 contains the comparison of the models.
The GVC model differs from the PVC model in various aspects and its system is built on a different logic. Both models put young and innovative firms into their centers, but with different motives. In the PVC model, young and innovative companies provide a market niche whereas a result of market imperfectionsother market participants are not willing or able to appear. This niche provides an opportunity for investors to exploit the economic potential of these companies in order to maximize their profits. In this sense, funding them is a necessary tool for gaining extra profits. Therefore, by its very nature, PVC is targeting the young and innovative companies.
Although the targeted firms of GVC are also the young and innovative enterprises, its model relies on different motives. While the essence of PVCs is the private interest that drives them in creating and managing their portfolios, in the case of GVCs, although the profit maximization also appears as a goal, it is adjusted and sometimes even overwritten by economic policy rationales. The presumption of government intervention is that the supply of VC is sub-optimal and government funds can decrease welfare losses (Berger -Udell 1998). Of course, funding young and innovative enterprises is a tool, but in this case, it is a tool for spurring innovation, employment and economic growth. In theory, this goal could be consistent with profit maximizing behaviour, but if these firms were likely to be successful in commercial terms as well, then private investors would fund them. In this case, the economic policy rational overwrites the profit maximizing behaviour. This conclusion is strengthened by the results of Bertoni et al. (2015), who investigated the specific features of the European VCs with regards to the Young and innovative companies with high growth potential.

background of limited partners. Based on their study, GVCs focus is on those young and innovative companies that do not meet the requirements of other VCs, mostly in seed stage with specific industries. The economic policy-related decisions of GVCs are not consistent with PVCs therefore the number of syndicated investments is relatively low.
This inconsistency of goals hinders the efficient selection of firms. However, it is doubtful whether the government agencies are able to tackle the problems that market participants could not. Therefore, GVCs could lead to market distortions. If GVCs operate in an environment where information imperfections remain unresolved, then the funding of firms would lead to an adverse selection when the targeted companies are able to obtain capital, even though they are not viable. In addition to the short-term effect (low quality of the investments) on the long-run, the prospects of young and innovative firms might get even worse, as the poor performance of GVCs leads to worse valuation for these enterprises.
There is also a difference in the dimension of cooperation between PVC and GVC. There is a consensus in the literature about the role of venture capitalist special expertise (Fried -Hisrich 1994;MacMillan et al. 1998;Harding 2002;Lerner 2003;Fazekas 2016;Becsky-Nagy -Fazekas 2015). This special expertise provides a foundation for PVCs to overcome the market imperfections more efficiently than other private participants. Based on international evidence, general partners (GP) of GVCs are less experienced and less efficient in the identification of viable investment targets (Cumming -Macintosh 2006;Avinimelech -Teubal 2006;Becsky-Nagy -Fazekas 2017). Lerner (2003) emphasises that VC is not a uniform asset class, as there is a high heterogeneity in the non-financial value added services provided by the investors. This is also confirmed by the high variance of VCs returns (Kaplan -Schoar 2005;Phalippou 2010;Phalippou -Gottschalg 2009;Harris et al. 2014). The performance of VCs depends on the structural factors of capital, competence and cooperation (Becsky-Nagy 2016). Furthermore, these factors show a dynamic development; the more experienced the VCs are, the more valuable their nonfinancial services are. Cooperation with GVCs is limited to the monitoring of firms; therefore, they are not able to implant the necessary competence and bridge the knowledge gap for young and innovative firms. This is consistent with the international evidence that suggests that GVCs are able to improve the invested firms' performance only if they supplemented PVCs. In the absence of close cooperation and control, the quality of the investments might decrease (Devenow -Welch 1996).
Both PVC and GVC models represent some form of financial intermediation with information asymmetries. At first Sahlman (1990) provided a detailed discussion of the two-level principal agent relationship and the complex moral hazard issues that evolve in the PVC model. In the GVC model, where the limited partners (LP) are public agencies, the process becomes more exposed to the moral hazard issues, as in the case of public funds a multi-level principalagent relationship evolves (Lane 2000). While in the PVC model, there are various practices reducing the risks of principal-agent relationship, in the case of GVC, the extent of the problem depends on the regulation, transparency and institutional environment of the system. However, a strict regulation might restrict the efficient operation of investors (Karsai 2018). Baldock (2016) highlighted based on international evidence that overregulation in terms of government agendas' scale and scope might hinder efficiency.
GVCs by their nature are not able to imitate the cooperation and the strategic assistance of PVCs and, at the same time, economic policy goals hinder the efficient selection of the firms. The model of GVCs (its different goals and the tools connected to them) therefore predestines the poorer performance of the GVC backed enterprises. The international evidence supports the conclusions of this model. It is also obvious based on the theoretical and empirical evidence that in the long run, an efficient VC market cannot rely on GVCs. It is also out of the question that young and innovative firms are essential parts of a healthy entrepreneurial system. In the absence of PVCs, the only rational goal of the GVC schemes can be to develop the market to a point where private participants are willing and able to sustain the VC market. The role of GVCs is to catalyse the development process. In this sense, the indirect effects of GVCs on the ecosystem of young and innovative firms is even more important than their direct effects on the invested companies. These agendas cannot be evaluated purely on the basis of the performances of the invested firms. Within the indirect effects, we can mention the accumulated experiences and the learning processes of market participants that are generated via GVCs' investments. Especially in the case of an emerging market's developing infant industry, the knowledge generated by the investments may lead to the formation of an ecosystem that could attract PVCs.
3.2. The theoretical model of hybrid venture capital agendas 3.2.1. Incentive schemes of HGVCs. HGVC has become an increasingly dominant form of government backed VC. The goal of hybrid VC agendas is to overcome the inefficiencies of the GVC model by attracting private investors. In theory, HGVC is a step forward towards a selfsustaining VC market as it relies on the participation of the private sector. In theory, as HGVC incorporates the competence of private investors, their superior non-financial value added services lead to a more efficient use of public funds. Yet, the complex system and the incentives built into HGVCs might lead to various distortions and to the misuse of public funds.
As in PVC there is a two-level principle-agent relationship, the properly designed incentive scheme became an important element of the private funding model. The success of PVC scheme relies on overcoming the moral hazards between the limited and general partners by harmonizing their interests. In PVC carried interests and the contribution of LPs to the fund's capital are the most commonly used tools that harmonize the participants' goals by incentivizing LPs to select and manage the invested firms to the best of their abilities. Incentives create a funding scheme where these actions maximise the utility of LPs and GPs and at the same time lead to the efficient allocation of resources.
In contrast to the PVC model, in HGVC the role of incentive scheme is not only to harmonize the interests of LPs and GPs. A pivotal question of these agendas is how to incentivize the private participants to take part in the funding of young and innovative firms. Table 3 summarises the commonly used incentive systems aiming the participation of private actors.
Compensation of expenses broadens the investment horizon as it increases the yields realized by the private investors, so a wider range of enterprises is able to meet the profit expectations of the private VCs. In the co-investment HGVCs, capital is provided partially by private LPs or they are required to make joint investments with private investors. The benefits of this form derive from economies in scales and diversification. Preferential timing of cash flows results in shorter duration therefore the international rate of return (IRR) for private LPs is higher. Each of these schemes provide benefits for the private participants, but they have to take the profits and losses after their investments; therefore, these schemes cause the lowest distortions.
Profit leverage schemes modify the risk-return characteristics of the investments for private participants in order to make the VC-type investments more attractive, but at the same time these incentives influence the investment decisions. HGVC activity is, therefore, exposed to a higher distortion. Options and profit ceiling enable for the private investors to gain additional profits without taking additional risks. Thus, they lead to an increased risk-taking. Loss mitigation also attracts more risk-averse investors, but at the same time, it increases the chance of moral hazards. The various incentive schemes are not used separately; usually, these agendas incorporate their combinations. While the incentives are inevitable to attract private participants, their extended use can lead to an adverse selection, the agendas will fail in improving the funding prospects of young and innovative firms and their negative effects will exceed their benefits. The following section discusses the role of the incentive schemes in the HGVC model.
3.2.2. The model of hybrid VC. The HGVC model combines commercial rationales with economic policy principals, but its model is different than the simple mix of PVC and pure GVC models; the mix of the motives creates a model based on unique fundamentals. Decrease of expenses therefore yields for private limited partners increase.
Co-investment Provision of a part of capital. The benefits of economies of scales and diversification as a result of larger funds.
Timing of cash-flows Private investors contribute capital last and receive cash disbursement at first.
The same profits can be realized under a shorter period therefore IRR is higher for private investors.

There is an extensive literature discussing the design of government backed VC initiations. There is a consensus in the literature about the role of private participation in the government backed VC agendas; public funds should be used in cooperation with private sector participants (Lerner 2009;Reid -Nightingale 2011;Karsai 2015;Baldock 2016). There are two prevalent forms of such cooperation in HGVC agendas; public funds are channelled to young and innovative firms with the government as a co-investor or by a fund of funds managed by a government agency (Karsai 2015). In the co-investment structure, public funds augment the capital of private investors and the funds are managed by private VC firms. Another widespread structure of HGVC is when public funds are invested into privately managed VCs via a fund-offunds, and only those VC firms can compete for the management of public funds that target firms what are in the scope of government agendas (Murray 2007).
Based on the international evidence there are certain criteria of efficient government backed VC agendas. Research paper in the field emphasized the role of long-term planning, the facilitation of follow-on investments, adequate scale of funds, flexible regulation, no regional restrictions, reshaping the agendas to correspond to the changing entrepreneurial environment and the agenda level exit strategy (Lerner 2009;Murray 2012;Karsai 2015;Baldock 2016). These recommendations are connected to the practical design of government backed agendas, in general, but on the other hand, they do not tackle the problems deriving from the conceptual model of HGVCs.
The HGVC model is a two-goal system with economic policy rationales connected to government funds and profit maximization motives of private participants. The specific problem of HGVCs steams from this two-goal system as the motives of participants are in conflict. Based on their economic policy motives, HGVCs target young and innovative firms, which is inconsistent with the profit maximizing behaviour of private participants; if the private investors would perceive young and innovative firms as the investment opportunities that maximize their utility, then they would appear on their market even in the absence of government interventions. Based on the assessment of private investors, young and innovative firms fall behind their profit expectations and, according to their perceptions, there are more favourable investment targets on the market. While the PVC and GVC models inevitably target young and innovative firms either led by profit maximizing or economic policy motives, the hybrid model is inconsistent in its goals and the funding of young and innovative firms does not derive from the logic of the model as it contradicts the private interests. Targeting young and innovative firms in the HGVC model relies on regulation rather than on the decisions of private participants led by economic rationales.
The underlying principle of HGVC model is that market failures lead to a sub-optimal capital supply for young and innovative firms and the perceived profit potential of these firms falls behind the expectations of private investors. By providing incentives described in the previous section, the HGVC model bridges the gap between the perceived and expected return of private investors and tries to harmonize the economic policy and profit maximizing goals. These incentives are double edged swords; they are necessary in order to crowd in private participants 1 but they also inevitably lead to distortions on the market. The distortions can be 1 If the private investors are willing to appear on the market in the absence of incentives, then the government intervention itself becomes redundant. amplified by the combined use of different incentive schemes like the mix of profit-leverage and co-investment. In the design of HGVC agendas, the proper incentive scheme plays a pivotal role and it must resonate with the development of the market; the more developed stage the market is in, the lesser level of incentive is justifiable. In this sense, the optimum of incentives is that minimum level where the private participants are willing to appear on the market.
The presence of incentives and the conflicting goals of public and private participants expose HGVCs to increased moral hazard problems. The rational interest of private participants is to benefit from the incentives while pursuing those activities that they perceive as the profit maximizing ones. Captive fundswhere the LPs and GPs are not independentrepresent a specific case of this problem. In their case, it is possible to internalize the economic benefits of incentives, and therefore, to gain profits without real business successes or fulfilling the economic policy goals. As a result, if the incentive scheme, investment policy and transparency of agendas are not regulated properly, in the short run, HGVCs might lead to even higher misallocation of capital than GVCs. In the long run, adverse selection might even increase as the inefficient capital allocation, and therefore, the poor performance of HGVCs signals that the targeted companies are not viable investments.

CONCLUSIONS
International evidence suggests and most research in the field agrees that governments have an important role as catalysts in the vivid entrepreneurial systems. Therefore, the questions regarding the efficient design of government backed VC agendas have utmost importance, as many of these agendas fail on a conceptual level by misunderstanding the mechanisms of VC. By creating the model of government backed VC, the current article aimed to provide a consistent theoretical framework for these agendas regarding their nature and mechanisms.
The direct effects of VC on invested firms are diverse, depending on the geographical location and the maturity of industry. In more developed entrepreneurial ecosystems, VC is able to create a value in terms of innovation and growth, while in less developed regions, VC has a meagre impact and invested firms, in many cases, underperform than their non-VC backed peers. These results suggest that VC is embedded into the entrepreneurial systems and the number and quality of young and innovative firms limit the effectiveness of investments both in the cases of private and government backed VC. These results lead to the conclusion that without a proper institutional environment young and innovative firms cannot flourish. Therefore, in the developing ecosystems, indirect government agendas prelude direct interventions.
The performance of invested firms suggests that PVC is more efficient funding scheme than any form of government backed VC. Our conclusion is that this difference is inherent in the models of different types of VC. Different goals of government backed VCs, the conflicting interests of participants and more complex moral hazard issues predestine their inferior performance relative to PVC.
In the GVC model, economic policy rationales overwrite the profit maximizing goals of PVCs; therefore, the selection of invested companies becomes biased and the problem of adverse selection may arise as non-viable firms are able to obtain capital. Moreover, it seems obvious that GVCs are not able to imitate those non-financial value added services that play a central role in the success of PVC. The GVC model predestines the relative underperformance of firms financed by GVCs, because economic policy rationales dominate private interests. Yet, as a catalyst, these investments might be the first steps towards a self-sustaining market, since they increase the industry level knowledge and have a pull effect on the institutions of the start-up ecosystem. Consequently, the government intervention is justifiable only in the case of supoptimal PVC activity in cases of the developing industries.
The HGVC scheme appeared in the field of direct government intervention which is, in theory, a step forward compared to GVC, as it tackles the two major problems, e.g., the lack of private interest and special expertise of private investors, by including private participants. On the other hand, the empirical evidence raises questions regarding the efficiency of HGVCs. The theoretical framework of the HGVC model shows that by crowding in private participants, this scheme creates a complex two goal system where private profit maximising interests are in conflict with the economic policy goals targeting the funding of young and innovative firms. If the private participants would perceive young and innovative firms as viable investments, then they would appear in their market even in the absence of public interventions. Incentives built into HGVC schemes provide economic benefits for private participants that bridge the gap between the expected returns of investors and the perceived returns they attribute to young and innovative firms. On the other hand, as a result of conflicting interests, the HGVC model is exposed to increased moral hazard issues and, if poorly supervised and regulated, they might lead to higher distortions on the market than GVC. Information asymmetries and moral hazard issues change the PVC model as well, but in this form, profit maximisation is a common denominator for participants and with properly designed incentives, private interests create a consistent system. However, within the two-goal system of HGVC, such harmonization is unlikely and the mix of private interests and economic policy goals create inconsistency in the model. This inconsistency is the reason why, although in theory, the involvement of private participants in HGVC is a step forward in the area of direct government interventions, in reality the success of this model relies on proper regulation and incentive system.
