\begin{abstract}
Starting a firm with expansive potential is an option for educated and
high-skilled workers. This option serves as an insurance against
unemployment caused by labor market frictions and hence increases the
incentives for education. We show within a matching model that reducing the
start-up costs for new firms results in higher take-up rates of education.
It also leads, through a thick-market externality, to higher rates of job
creation for high-skilled labor as well as average match productivity. We
provide empirical evidence to support our argument.

\section{Introduction}
The importance of entrepreneurship is gaining more attention.\footnote{%
See for example the Comission of the European Communities (1999) and the
OECD (1998a, b).} The prime arguments to support the creation of new
businesses concern innovation, the expansion of the `boundaries of economic
activity' (OECD, 1998b), and the adaptability of economies towards new
opportunities. Governments and Chambers of Commerce argue that reduced
start-up costs for new businesses are a potential cure for the ailing
European labor market.
Reductions in start-up costs can take two forms. One is to reduce the
bureaucratic hurdles that increase the start-up costs for new firms. The
second is to provide institutions for venture capital as well as public
financial support for new firms.\footnote{%
Another aspect of venture capital and its effect on labor markets is
discussed theoretically and empirically by Belke et al. (2003). They argue
in a matching framework that the availability of venture capital helps to
select better managers.}
In this paper we study the implications of lower start-up costs in the
situation that new firms (at least, those with high productivity) can only
be set up by high-skilled persons. Lower start-up costs then affect
education choices by improving the options of skilled workers. This direct
skill dividend to the labor market triggers, through a search externality, a
second dividend: because the odds of getting high-skilled workers to apply
for a given vacancy goes up, already existing firms create more jobs for
high-skilled workers. We provide a model that identifies both these effects.
The current literature on starting firms focuses on the firm level and on
how new firms influence existing markets.\footnote{%
Much empirical research can be found on these issues. To name two examples:
Audretsch et al. (1999) study industry dynamics of industries and how the
survival of new firms depends on start-up costs as well as industry
characteristics. Gans et al. (2002) look empirically at the effects of
start-up costs on the trade of ideas, innovation, and the founding of new
firms in an industry.} Our contribution is to endogenize education decisions
in this framework. Is there, however, any `prima facie' empirical indication
that lower start-up costs are related to educational choices? Figures 1 and
2 indeed show that two separate measures of start-up costs, namely the
number of days it takes to set up a new firm and the availability of
start-up finance, correlate with education choices.

At the very minimum, these graphs suggest there is some merit in further
investigating a positive link between low start-up costs and incentives for
high-skilled education.
Our matching model is in the vein of Pissarides (2000) and Fonseca et al.
(2001). In equilibrium, high-skilled workers first search for a high-skilled
vacancy with existing firms. Search frictions prevent a perfect match
between high-skilled vacancies and high-skilled job seekers. Some
high-skilled unemployed then opt for setting up new firms until the value of
outside low-skilled employment equalizes the value of creating a new firm.
The equilibrium proportion of high-skilled vacancies is then determined by
the proportion of high-skilled workers in the pool of unemployed, which
links the proportion of high-skilled vacancies with the outside option for
high-skilled workers of setting up a new firm. This gives rise to a matching
externality: a larger share of high-skilled workers will increase the
profitability of posting a high-skill vacancy for existing firms. This
increases the number of high-skilled vacancies created when start-up costs
for new firms decrease. Through this `thick market externality' higher
education rates lead to more job creation for high-skilled workers and this
again adds to the incentives to invest in education. Under the specific
assumptions of our model, lower start-up costs increases production and
reduces the number of workers filling low-skilled jobs.
Closest to our approach is Fonseca et al. (2001) who study the effects of
start-up costs in a matching model where workers are heterogeneous with
respect to the potential profit of starting a new firm. Whilst not
considering education, they also argue that lower start-up costs lead to
more firms being created and less unemployment. The effect of reducing
start-up costs on the efficiency of the market is ambiguous in their model:
if too many workers start new firms, the workforce may become too small and
output suffers. In contrast, lower start-up costs are always beneficial for
the economy in our model.
A related line of enquiry is the link between education choices and search
frictions. Acemoglu (1996) provides the basic intuition: workers decide on
their investment in education before knowing whether they are able to find a
high-skilled job. A higher proportion of educated workers then leads to more
firms creating such jobs implying a wedge between private and social returns
to education. Burdett and Smith's (2002) `low skill trap' is based on a
similar intuition: they provide a model with search frictions in which
multiple equilibria exist, where firms offer either too few or too many
high-skilled jobs and workers either acquire or refrain from acquiring
skills.\footnote{%
Masters (1998) studies the differences of wage bargaining vs. fixed rent
sharing agreements in a model with investment by firms in capital and
investment by workers in education. He finds that inefficiencies in the
market have to be attributed to both search frictions and inefficiencies in
the determination of wages.} Where these papers differ from our is that in
our model search frictions are bounded by the option of setting up one's own
firm.
Other policy options that affect the education choice of individuals are
considered in the matching literature. Belot (2003) models education choices
and migration options in case of labor market frictions. She argues that
policies that increase migration possibilities thus also increase the
incentives to invest in education. Another policy option is unemployment
insurance, which effectively reduces the importance of unemployment risks
and hence stimulates the unemployed to look for higher-paying riskier jobs.
Acemoglu and Shimer (1999) show that unemployment insurance can thus be
output increasing when the unemployed are risk-averse. When the possibility
of taking a risky jobs is related to particular education choices,
unemployment benefits affect education choices.
Our baseline model presented in Section 2 captures the basic search-friction
argument. In Section 3, the baseline model is extended with the opportunity
for high-skilled persons to start a new firm. We discuss and interpret the
comparative statics of the model. We also provide a short discussion on the
differences between policies to reduce bureaucratic hurdles vs. policies to
provide venture capital. Section 4 contains empirical evidence that supports
the main prediction of our model, namely the effect of start-up costs on
skill acquisition. Section 5 concludes. All tables can be found in the
Appendix.
\section{A Matching Model with Education}
\subsection{The Basic Model}
The economy consists of a fixed large number of firms and $N$ workers. We
consider a matching model with two time periods. In period one the workers
in the economy decide whether they enroll in education and firms choose the
number of vacancies for high and low-skilled jobs. In the second period,
firms and workers are matched and production takes place.
With respect to the cost of education, workers have an innate ability $%
\theta \in \lbrack 0;1]$. Ability is distributed over the population
following a continuous cumulative distribution function $Q(\theta )$ on the
support of [0,1]. Workers that choose to invest in education incur a cost of
$e(\theta )$. By assumption, higher ability individuals have lower costs of
education, i.e. $\frac{de(\theta )}{d\theta }<0$. To guarantee an interior
solution we assume that education is free for the most gifted worker ($%
e(1)=0 $) and impossible to achieve for the least gifted ($e(0)=\infty $).
In all subsequent arguments, this will lead to a cut-off ability $z$ above
which workers become educated and below which they do not. Then, $1-Q(z)$ is
the share of workers becoming educated.
Firms can offer two types of jobs: low-skilled jobs and high-skilled jobs.
To post a low- (high-)skilled vacancy imposes costs of $c_{l}$ ($c_{h}$) on
the firm. We denote the overall number of vacancies as $V_{l}$ and $V_{h}$.
Low-skilled jobs can be performed by any type of worker whereas high-skilled
jobs can only be filled by high educated workers. Matching individuals to
high-skilled jobs is by assumption more difficult than matching individuals
to low-skilled jobs. For simplicity, we assume frictionless matching on the
low-skill labor market, i.e. there is a spot-market for low-skilled jobs.
The number of low-skilled matches equals $M_{l}=\min \{N_{l};V_{l}\},$ with $%
N_{l},V_{l}$ the number of workers seeking low-skilled jobs and the number
of low-skill vacancies, respectively. Think of low-skilled jobs as
hamburger-flipping positions which can be found at virtually no cost at all.%
\footnote{%
Assuming frictions on the market for low-skilled labor does not change the
basic story because an increased probability of unemployment merely
increases the value of the option to start a new firm.}
With respect to high-skilled jobs we assume that matching frictions are
captured by a constant returns to scale matching function $m(N_{h},V_{h}).$
The number of educated workers $N_{h}$ is equal to $(1-Q(z))N$. The number
of successful high-skilled matches equals $M_{h}=m((1-Q(z))N,V_{h}).$
Unsuccessful educated workers enter the low-skill labor market, which means
we assume matching first takes place for high-skilled jobs and then for
low-skilled jobs. The number of individuals prepared to accept low-skilled
jobs thus equals $N-M_{h}.$
A successful match has productivity $p_{l},p_{h}$ respectively. We assume
that wages in successful matches are determined by instantaneous
Nash-bargaining where the power of workers is independent of education and
equals $\beta $: wages are given as $w_{l}=\beta p_{l}$ and $w_{h}=\beta
p_{h}.$ To ensure that production takes place we assume $(1-\beta
)p_{j}>c_{j}$, $j\in \{l,h\}.$ If this would not hold, there would be no
low-skilled (high-skilled) workers at work, which is a trivial case.
\subsection{Analysis of the Basic Model}
We start with the behavior of firms with respect to low-skilled jobs. Firms
will obviously set up low-skilled vacancies when there is a surplus in doing
so. This is the case given the assumption on productivity: ($p_l-w_l$) is by
assumption bigger than $c_l.$ To maximize profits, firms will post vacancies
as long as the marginal expected profit is non-negative. This `free entry'
conditions for low-skilled vacancies implies that the number of posted
low-skilled vacancies solves
\begin{equation}
\frac{N-M_h}{V_l}(p_l-w_l)-c_l=0. \label{eMl2}
\end{equation}
The solution is $V_{l}=\frac{N-M_{h}}{c_{l}}(p_{l}-w_{l}).$ This must be
higher than $N-M_{h}$ because $p_{l}-w_{l}>c_{l},$ which shows that there is
an over-supply of low-skilled vacancies. This is rent-dissipation.
The number of individuals that chooses to become educated is determined by
the condition that the marginal individual is indifferent between becoming
highly-educated or not. The equation determining $z$ is given as
\begin{equation}
\frac{m((1-Q(z))N,V_h)}{(1-Q(z))N}(w_h-e(z))+(1-\frac{m((1-Q(z))N,V_h)}{%
(1-Q(z))N})(w_l-e(z))=w_l \label{eNh2}
\end{equation}
For the firm, setting up a marginal high-skilled vacancy must have
zero-profits, which implies
\begin{equation}
\frac{m((1-Q(z))N,V_h)}{V_h}(p_h-w_h)=c_h \label{eMh2}
\end{equation}
The following proposition states the result for the basic model.
\begin{proposition}
In the basic model with education and low- and high-skilled jobs there
exists a unique equilibrium, described by a set $\{\tilde{V}_h,\tilde{V}_l,%
\widetilde{z}\}$ where $\tilde{V}_h,\tilde{V}_l,\widetilde{z}$ denotes the
equilibrium number of high- and low-skilled vacancies and the cut-off
ability respectively.
\end{proposition}
%TCIMACRO{\TeXButton{Proof}{\proof}}%
%BeginExpansion
\proof%
%EndExpansion
The proof runs via standard arguments: The productivity and the bargaining
power uniquely determines $V_l.$ Equations (\ref{eNh2}) and (\ref{eMh2})
determine $\widetilde{V}_h$ and $\widetilde{z}$. Only one solution exists
because for a given $z,$ the marginal profit of an extra vacancy for
high-skilled is monotonically decreasing in $V_h.$ This implies there is
only one (finite) level of $V_h$ for any given $z.$ Finally, the value of
becoming high-educated is monotonically increasing in $\theta $ because of
the decreasing education costs. Because of the assumptions on $e(.),$ there
will be a unique level of $z$ at which an individual is indifferent. This
level is $\widetilde{z}$. In the simple model we hence have a unique
equilibrium set \{$\tilde{V}_h,\tilde{V}_l,\widetilde{z}$\}.%

\section{Business Start-ups}
\subsection{Model Extension}
We introduce the possibility for educated workers to start a business. The
type of business we have in mind is obviously one with high productivity.
This means we abstract from `new firms' that are actually a form of
low-skilled employment such as street vending.
An individual setting up his/her own high-skilled production job has to bear
the cost $SC.$ We assume that firms are more efficient in setting up such
jobs than the unemployed are and that $\beta $ is large enough such that
accepting a high-skill job in a firm is more attractive to an educated
worker than to start a business: $w_{h}>p_{h}-SC$ or $SC>(1-\beta )p_{h}$.
This assumption implies $SC>c_{h},$ which reveals the intuition for the
existence of firms in this economy, namely that economies of scale exist: a
firm is more efficient than the unemployed in creating new jobs. To ensure
that starting a firm is attractive for an educated worker in case of being
hit by labor market friction, we assume $w_{l}p_{h}-SC>w_{l}$. All other cases are trivial.
\subsection{The Value of Starting a New Firm}
For the analysis, this new option changes the marginal condition (\ref{eNh2}%
) such that in equilibrium the following needs to hold
\begin{equation}
\frac{m((1-Q(z))N,V_h)}{(1-Q(z))N}(w_h-e(z))+(1-\frac{m((1-Q(z))N,V_h)}{%
(1-Q(z))N})(p_h-SC-e(z))=w_l. \label{eNhStart}
\end{equation}
This reveals the mechanism highlighted in this paper: becoming a
high-educated individual is now more attractive because of the outside
option of opening a new firm. This will unequivocally push down the
equilibrium level $\widetilde{z}.$ This, in turn, will push up the value of
a high-skilled vacancy for existing firms, which means more high-skilled
vacancies will be created, which will again increase the value of becoming
high-educated. Hence, $\tilde{V}_h$ will increase. We summarize this result
in the following proposition.
\begin{proposition}
Giving mismatched educated workers the option to start a new business leads
to a larger share of workers acquiring education and to an increase of
high-skill vacancies over the basic model.
\end{proposition}
%TCIMACRO{\TeXButton{Proof}{\proof}}%
%BeginExpansion
\proof%
%EndExpansion
The result follows from the previous proof. By assumption $p_{h}-SC>\beta
p_{l}$ hence the $e(z)$ solving equation (\ref{eNhStart}) must be larger
than the $e(z)$ solving (\ref{eNh2}), hence $N_{h}$ is increasing. That $%
\widetilde{V}_{h}$ increases follows from the monotonicity of $\widetilde{V}%
_{h}$ with respect to $N_{h}.$%
%TCIMACRO{\TeXButton{End Proof}{\endproof}}%
%BeginExpansion
\endproof%
%EndExpansion
To study the effects of reduced start-up costs, we consider the comparative
statics of an decrease in $SC.$ We proceed by stating the result of the
analysis in a proposition.
\begin{proposition}
A reduction in start-up costs $(SC)$ implies a higher rate of education and
more vacancies for high-skilled jobs.
\end{proposition}
%TCIMACRO{\TeXButton{Proof}{\proof}}%
%BeginExpansion
\proof%
%EndExpansion
The comparative statics yield the following equations:
\begin{equation}
\lbrack \triangle \widetilde{z}\frac \partial {\partial \widetilde{z}%
}+\triangle \tilde{V}_h\frac \partial {\partial \tilde{V}_h}][m(1,\frac{%
\tilde{V}_h}{N_h})(w_h-p_l+SC)+p_l-SC-e(\widetilde{z})]=(1-m(1,\frac{\tilde{V%
}_h}{N_h}))\triangle SC
\end{equation}
\begin{equation}
\triangle \widetilde{z}\frac \partial {\partial \widetilde{z}}m(\frac{N_h}{%
\tilde{V}_h},1)=-\triangle \tilde{V}_h\frac \partial {\partial \tilde{V}_h}m(%
\frac{N_h}{\tilde{V}_h},1)
\end{equation}
which immediately reveals signs: because $\frac \partial {\partial \tilde{V}%
_h}m(\frac{N_h}{\tilde{V}_h},1)<0$ and $\frac \partial {\partial \widetilde{z%
}}m(\frac{N_h}{\tilde{V}_h},1)<0,$ it follows that $\triangle \tilde{V}_h$
and $\triangle \widetilde{z}$ have opposite signs. Manipulating the
equations further, we obtain
\begin{equation}
\frac{\triangle \widetilde{z}}{\triangle SC}=\frac{(1-m(1,\frac{\tilde{V}_h}{%
N_h}))}{[\frac{\partial m(1,\frac{\tilde{V}_h}{N_h})}{\partial \widetilde{z}}%
+\frac{-\frac \partial {\partial \widetilde{z}}m(\frac{N_h}{\tilde{V}_h},1)}{%
\frac \partial {\partial \tilde{V}_h}m(\frac{N_h}{\tilde{V}_h},1)}\frac{%
\partial m(1,\frac{\tilde{V}_h}{N_h})}{\partial \tilde{V}_h}%
](w_h-p_l+SC)-e^{^{\prime }}(\widetilde{z})}
\end{equation}
\begin{equation}
\triangle \tilde{V}_h=\triangle \widetilde{z}\frac{-\frac \partial {\partial
\widetilde{z}}m(\frac{N_h}{\tilde{V}_h},1)}{\frac \partial {\partial \tilde{V%
}_h}m(\frac{N_h}{\tilde{V}_h},1)}
\end{equation}
Now, in the formula for $\frac{\triangle \widetilde{z}}{\triangle SC},$ the
terms with $\frac{\partial m(1,\frac{\tilde{V}_{h}}{N_{h}})}{\partial
\widetilde{z}}$ and $e^{^{\prime }}(\widetilde{z})$ are both positive, which
shows that $\frac{\triangle \widetilde{z}}{\triangle SC}>0.$ The
feedback-effect via the negative term $\frac{-\frac{\partial }{\partial
\widetilde{z}}m(\frac{N_{h}}{\tilde{V}_{h}},1)}{\frac{\partial }{\partial
\tilde{V}_{h}}m(\frac{N_{h}}{\tilde{V}_{h}},1)}\frac{\partial m(1,\frac{%
\tilde{V}_{h}}{N_{h}})}{\partial \tilde{V}_{h}}$ then increases $\frac{%
\triangle \widetilde{z}}{\triangle SC}$ again$.$%
%TCIMACRO{\TeXButton{End Proof}{\endproof}}%
%BeginExpansion
\endproof%
%EndExpansion
The analysis also shows how the first-order effect of the increased
profitability of education with the advent of the outside option is
amplified by the second-order effect of the increased number of vacancies
that firms provide as a reaction to the increase in the number of
applicants. It embodies the matching externality.
\section{Some empirical evidence}
The main prediction that our model generates is that lower start-up costs
increase the number of individuals opting to become educated.
As an empirical indicator of such human capital formation we use data on
educational enrollment from the UN World Development Indicators. These are
available for a large cross-section of countries. Data on start-up costs
come from two different sources:\ the Global Competitiveness Report (Porter
et al. (2000)) and Djankov et al. (2002). In the Global Competitiveness
Report executives in different countries were asked `whether venture capital
was easy to get'.\footnote{%
Venture capital in our model makes it easier for educated individuals to set
up their own firm. The main role of venture capital in the literature is to
lower $c_h,$ i.e. to make it easier for existing firms to create
high-skilled vacancies such as via the financing of R\&D activities of old
firms.} Djankov et al. (2002) constructed an international database that
quantified the regulation of entry of new firms. They went to considerable
lengths to collect national information on the costs of starting a new firm,
including the number of procedures, and the time and cost of obtaining legal
status. They not only checked the available written information but also
contacted the relevant government agencies in the countries and commissioned
independent reports on entry regulation from local law firms as well. Both
the venture capital data and the regulation of entry data exist only for the
year 1999.
Figure 1 of the Introduction showed the relation between the `ease in
obtaining venture capital' and tertiary school enrollment for 58 countries.
These indicators show a very high correlation of 0.69. Likewise, the
variable `log(days to obtain legal status)' shows a very significant
negative correlation with tertiary enrollment for 83 countries - see Figure
2. Very similar relations are obtained for secondary school enrollment rates.%
\footnote{%
Enrollment rates are gross enrollment rates; i.e. the number of students
divided by the relevant population, which might result in enrollment rates
of more than 100\% for secondary education.}
Table 1 shows correlations between our two schooling indicators and four
different indicators for start-up costs: the venture capital indicator, time
needed to get legal status, costs associated with obtaining legal status and
the number of procedures which are necessary to start a firm. All of these
indicators are highly correlated with each other and with school enrollment.
Looking beyond simple correlations, we now try to explain school enrollment $%
E_{i}$ using more variables$.$ The included variables are an indicator for
start-up costs or venture capital ($VEN_{i})$ and some control variables:\
GDP per head ($Y_{i})$, total public expenses for education ($PUB_{i})$%
\footnote{%
See e.g. Winter-Ebmer and Wirz (2002) for the relation between pubic funding
and enrolment into higher education in Europe.}, the illiteracy rate of
adult males ($IL_{i})$, the unemployment rate of youths ($U_{i}),$ and an
indicator for the share of urban population in the country ($URB_{i})$. It
can be argued that all of these variables influence school enrollment
directly. The illiteracy rate of adults takes account of the
intergenerational correlation in education enrollment which is well
documented in the literature (Solon, 1999); the unemployment rate of youths
can be seen as an indicator of the opportunity costs of youth while deciding
about further education; a higher share of the population living in urban
centers indicates both a general level of development and the availability
of schooling institutions. A Table in the Appendix shows descriptive
statistics for all the variables used in the analysis.
OLS results for tertiary enrollment are in Table 2 whilst those for
secondary enrollment are found in Table 3. In both tables we experiment with
the four different indicators for start-up regulation or venture capital
shown above. The results are remarkably similar across specifications. Our
indicators for start-up regulation always have the right sign and are
statistically significant most of the time. The assessment by executives if
`venture capital is easy to get' varies in the data between a low of 1.9 and
a high of 6.4. Increasing this assessment by one standard deviation (1.05)
would increase tertiary enrollment by almost seven percentage points. The
quantitative effect of registration time is somewhat smaller:\ decreasing
the time necessary to obtain legal status by one standard deviation of our
data set (60 percent) would increase enrollment by 3.6 percentage points.
The effects of the other variables always have the anticipated sign, but
lack statistical significance in many cases; only the coefficient of GDP is
always statistically significant.
\subsection{Robustness analysis}
One potential problem with these results is the possibility of missing
confounding variables or the endogeneity of start-up costs. It could be the
case that both school enrollment as well as start-up regulation are caused
by third factors like the climate towards entrepreneurship. As an attempt to
deal with such problems, we instrument start-up costs by political variables
which we assume to affect start-up costs directly but school enrollment only
indirectly. The essential reason for this is that political choices can
almost immediately affect start-up costs, but not directly education
enrollment: in the short-run, enrollment levels are the result of the
choices made by students and not government which makes the effect of
political decisions indirect in the short run at least. As our instruments
we use data on the political system from Botero et al.\ (2003) and Djankov
et al. (2002).\footnote{%
These include: 1) Party affilliation: the percentage of years between 1975
and 1995 during which the party of the chief executive and the largest party
in congress had leftist orientation; 2) Indicators for the origin of the
legal system; 3) An indicator for autocracy indicating the `general
closedness of political institutions';\ and 4) an indicator for property
rights.}
Tables 3 and 4 report our estimates for the different start-up indicators.
To test for the relevance of our instruments, we include indicators for the
goodness of fit of the first-stage regressions, i.e. the marginal $R^{2}$
and the F-Test for the excluded instruments. The explanatory power of the
instruments is quite good, though less so for the venture capital indicator.%
\footnote{%
This might be due to the fact, that - while the venture capital indicator
relates to the financial infrastructure of the country - the other three
indicators are related to legal circumstances which are more responsive to
political and legal factors.} The coefficients for the start-up costs in the
IV specification are fairly similar to the OLS\ results. The coefficients
are of comparable size and six out the eight relevant coefficients are
statistically significant at the 10 percent level. It has to be said,
though, that the null hypothesis that all instruments are orthogonal to the
error term in the second stage (the Sargan-test for overidentification)
fails in some cases, especially for secondary school enrollment. The results
for secondary school enrollment should therefore be interpreted with care.
\section{Conclusions and discussion}
The present paper attempts to shed new light on the discussion about
start-up costs for new firms. Whereas the standard argument in favour of
lower start-up costs is that mismatched workers can then start their own
firm, we argue that lower start-up costs also provide incentives for
education. This is because new firms (at least those with expansive
potential) are often set up by high-skilled workers. Lower start-up costs
therefore not only increase production but also lead to a higher proportion
of individuals choosing high-skilled education. In the presence of search
frictions this improvement in the skill-composition of the labour force can
furthermore increase the number of high-skilled vacancies. A corollary is
that incumbent firms - who are supposed to lose in general from increased
competition - can also gain from reduced start-up costs via the
skill-composition effect that reduces the tightness of the job-market for
high-skilled labor.
The empirical evidence on the effects of start-up costs on enrollment, which
bears the usual caveats of being qualitative and available for few periods,
strongly supports our model. Increasing the assessment of managers as to the
ease with which venture capital is available by one standard deviation would
increase tertiary enrollment by almost seven percentage points. Decreasing
the time necessary for a new firm to obtain legal status by one standard
deviation would increase enrollment by 3.6 percentage points.
Our results, if true, also reflect upon the discussion of whether education
actually provides skills or just a signal of ex-ante existing skills. The
present theoretical model assumes that education improves the skill level of
a worker and has no signalling function.\texttt{\ }In a signalling model of
education, workers need to provide the education certificate to signal their
quality; no such signal is needed to be your own boss. Lower start-up costs
in a signaling context would therefore reduce the incentive for (ex-ante)
high-potential individuals to invest in the signal. Then, empirical evidence
should reveal that lower set-up costs lead to lower tertiary education
rates. The presented empirical evidence strongly suggests otherwise and
hence supports the theory that at least some skill acquisition takes place
during education.
