Does Business Cycle Have an Impact on Entrants and Exits?

Purpose: The role of entrants and exits has enlarged indisputably over recent years. The basic explanation s connected to the deepening of innovation's influence on industrial growth. Furthermore, new businesses have to be more effective, and based on products, technological or organizational innovations, and exits have to be ineffective (respectively unprofitable), based on denoted products or technology. Design/methodology/approach: According to the above-mentioned prerequisites, policymakers need to manage the role (respectively the impact) that entrants (new start-up companies) and exits play in industrial growth. Nevertheless, this impact is not a cornerstone of the Bulgarian National Strategy, or the Europe 2020 Strategy. Findings: The paper tries to answer the following two questions: 1) Do new start-up companies and exits have any role and influence on economic growth in Bulgaria? and 2) Does the role (respectively the impact) of entrants and exits in industrial growth change according to economic cycle? Research limitations/implications: In addition, according to the Lisbon Strategy, as well as the European Union's (EU) Strategy 2020, the current economic policy supports entrepreneurship and innovations. Thus, the establishment of innovative companies, as well as the development of innovative, incumbent business are core issues of EU economic policy for the past decade. Originality/value: The paper builds on the industrial dynamic methodology and on the understanding of how business decisions (entrepreneurship, innovations, and R&D) on micro level correspond to macro level (GDP growth and innovation policy).


Introduction
Over the past 70 years, various methods have been utilised in understanding the economic impact of entrepreneurship. However, the answer to the question: Do new start-up companies and exits have any role and influence on economic growth? is still unanswered because of the ever-changing economic conditions.
Understanding start-ups has recently been based on the concepts of innovation and competitiveness, and focused on start-up companies with growth potential.
Thus, start-ups were identified recently as one of the effective pillars supporting the growth and development of a modern economic system. Not surprisingly, such companies receive special status; they have been placed at the centre of developed EU countries' strategic objectives via appropriate economic and social policy mechanisms in the EU's 'Europe 2020' growth strategy.
Moreover, these companies are nowadays defined as those entering the 21st century's highly competitive globalized market. Investigations so far indicate that over 90% of these companies went bankrupt in the first year of their operation. So, what is the relationship between start-ups and real economic growth? Answering this question could help establish the role (respectively, the impact) start-ups play in economic growth. Some preliminary observations show insufficient evidence of real impact on economic growth in Europe, and Bulgaria. Additionally, the effect of startups on the growth of the Bulgarian economy is slightly exaggerated.
Our preliminary considerations are based on some characteristics of the economic environment in Bulgaria that make it difficult for start-ups entering the economy: • it is difficult for new start-ups to access financing, especially for innovation; • the also encounter very high initial insurance premiums; • they enter into a highly competitive EU market, and a declining domestic market; • many Bulgarian start-ups lack specialization as a result of ongoing educational reform.

State-of-the-art
Our analysis is based on three key problems: • How do we inspire economic growth?
• What role do entrants and exits play in economic growth?
• How do we measure the impact of entrants on economic growth and respectively, understand the role of the start-up?

Start-ups and Economic Growth
Start-up companies are part of the contemporary economic system that contribute to economic growth. Recently, they have become of increased economic importance because of their growing participation and influence in the gross domestic product. This is a result of the specificity of start-ups, since part of their core function is to produce innovative and, in most cases, high-technology products and services with high addedvalue, which in turn leads to growth in gross domestic product.
Analysis of the role start-ups and their ability to innovate leads to the following preliminary findings: • In developing countries, industrial growth is linked to shifts in the factors of production (resp. labour, capital, materials, and resources) from low-to highproductivity sectors. So, growth and development are limited by the economy's capacity to generate new dynamic production activities (Ocampo, 2005). • Free-market economies attempt to develop industries that are expected to offer better prospects for economic growth (Pack H. and K. Saggi, 2003) by encouraging investments, especially in R&D, education and training (Sharp M., 2003) • Industrial growth is blocked by "entrepreneurial governance" that attempts to change the industry from the inside (Krafft 2006). However, in this approach, entrepreneurial behaviour collides with government institutions (March and Olsen, 1989).
A large number of publications on existing economic studies that explore the influence (resp. Effects) of participants (start-ups) and economic growth give different answers to the posed problems. In general, these studies primarily evaluated economic growth based on the total output growth (resp. Productivity growth). In summary, the state-of-the-art Sekkat K. (2010) describes three types of effect, as follows (see also : Foster, Haltiwanger and Krizan (1998), Aw, Chen and Roberts (1997), Hahn (2000), Griliches and Regev (1995), Baily, Hulten, and Campbel (1992)): • the structural effect between productivity factors, which is expressed by changing the intensity of labour and capital; • the innovative effect is expressed by the proportion of surviving entrepreneurial business; • the market effect, which results in a change in market shares.
These effects are not of equal impact on the different economic sectors; Scarpetta, Phillip, Thierry, and Jaejoon (2002) found that high-tech entrepreneurial companies contribute between 20% and 40% of overall productivity growth. In addition, these effects depend on the stage of economic business cycle (Disney, Haskel, and Heden, 2003).

Newcomers vs. Existing Business
Since the effect of start-ups on growth is explained well enough, we could summarize their basic advantages: • Existing businesses are known for their goals, strategies, and policies. From this perspective, a new start-up is an unknown quantity, which makes it an extremely quiet and invisible competitor. Undoubtedly, very rarely an established company retains its market position upon the emergence of a successful start-up business. • For existing companies, failure would be painful and for start-up companies, success would be painful. • A start-up business focuses on the medium of a new idea, and does everything to realize it. It delivers extra added-value for the user. In contrast, existing companies are focused on their existence: end revenue, financial results and growth potential. This makes them lessresponsive to changes in values and attitudes of consumers. = = . ) . + , ℎ ( + = 1)

Methodology
Preliminary methodological preview shows the next three effects that explain the mechanism of impact of start-ups on economic growth: • entrepreneurs are not sufficient enough for short-term growth but they are key to sustaining long-term growth; new businesses are procyclical, as they have a positive short-term economic impact; • start-up entities aid in employment and competition networking. However, these do not explain why highlyinnovative entrants really have a direct link to economic growth. Our analysis shows three reasons for the impact: • New start-up companies represent a highrisk profile, chasing rapid initial growth of profit and quick return on investment. • When the growth rate, which defines them as start-up companies, and expectations of a quick return on the initial investment are not achieved in the planned short timeframe, the company is restructured. • The goal of the investor is an increase in profit in the first months/years of activity, and return on investment within 2-3 years from the start of operations. In addition, to measure the impact of start-up on economic growth, we propose the following methodological steps of improvement: 1. Traditionally, industrial growth is presented by the following indicators: Total factor productivity (TFP) or labour productivity (LP) measured by labour (L) and Capital (K).

Analysis of Bulgarian case
The data used and represented in the analysis are given by the figures that aggregate micro data at mezzo (resp. Sectoral) level. The EUROSTAT database on SBS is the main source of data.
The main indicators are: value of sales, number of active (current) companies, number of start-ups, and number of closed companies. The figures for Bulgaria are provided for the period 2004-2013.
The database covers the following statistics available on the Eurostat website section SBS: • Production value (P) (code "V12120"): this is defined as turnover, plus or minus the changes in stocks of finished products, work in progress, and goods and services purchased for resale, minus the purchases of goods and services for resale, plus capitalized production, plus other operating income (excluding subsidies). The analysis is based on the consistent implementation of these steps that are given in the methodology, and the results represent the key moments explaining Formulae 4 and 5.

Source: Own calculations
The correlation test proves that all demographic parameters were significantly correlated with the dependent (resp. Production function). The degree of correlation is remarkably high (between 0.717 and 0.993), confirming the relationship between all production variables.
Step 2 is to estimate the dependency ratio between the effects of new start-up business and TFP. For the elucidation of these effects, two additional calculations are undertaken. 3.
Calculating the influence of the surviving companies (`a b ) and start-ups ( cad ) on the production function:  The role of newly established companies in the growth of production function is relatively weak, but is significant for its growth expressed in dynamics.
• Although the effect of start-ups on the production function is not important, the important thing is that the degree of correlation is negative (-0.063).
Step 3 is to estimate the impact of demographic variables on the growth of TFP. A regression analysis is applied ( Figure 1): The model explains the S-curve and introduces the need of start-ups to affect growth, additionally, there is a point after which the start-up business is not effective enough.

•
The impact (effect) of start-up companies on growth is insufficient and this impact is lower than the effect of the survival and exits on growth.
Step 4, to find out the parameter estimates of the production function and its derivate, we use a twostage least squares analysis as an extension of the OLS method ( Figure 2): Figure 2 confirms that increasing the number of newly-established companies does not lead to significant industrial growth in Bulgaria; growth however is achieved due to an increase in the number and importance of existing companies.

Figure 2. Annual change of the evaluated parameters of the business demographics that affect the production function
Moreover, the contribution of new businesses to the growth of the production function is 5 to 10 times lower than the contribution of existing and already-established companies. In addition, the number of exits negatively affects economic growth in Bulgaria for the analyzed period.
An additional conclusion is that the effect of start-ups is positive in the years of economic growth, and opposite -strongly negative -in the years of economic recession (2008)(2009)(2010).

Conclusions
Finally, economic growth in Bulgaria, based on the establishment and development of high-tech start-up business should be based on the use of appropriate industrial policy. The main reasons are summarized in the next three paragraphs: 1. The importance of new businesses is undoubtable for Bulgarian economic growth. However, nowadays Bulgaria does not make best use of these opportunities. Problems, basically, are summarized as; a range of key constraints and barriers to the creation of businesses by innovative and creative people. 2. Considering the importance of new-established businesses, as well as the barriers to their creation, contemporary industrial policy could use a mix of measurements that offers finance and provide help to businesses in the form of advice and vocational training. 3. Industrial policy should not be standardized, but appropriate support of new start-ups should be provided by existing institutional and regional structure, and based on established science and production support.
