Abstract : The paper presents new evidence explaining contractual pri-
vate funding of academic laboratories. We find that public funding crowds out
private one. While private funding increases with publications it decreases
with publications corrected for impact.

The last two decades have been a very disruptive context for academic
research funding : Shortening of public funding, evolving rationales and chan-
ging regulatory environments. One of the crucial issues relates to the rising
share of public research being funded through contractual relations with pri-
vate firms. Scholars mainly concentrate their attention on the consequences
of private contractual funding on research production : Expected benefits are
an increase of academic research due to extra funding and a shift in its econo-
mic relevance. Risks reside in a slowing down in the dissemination of findings,
a shift toward applied research and a decrease of research productivity1.
The present paper focuses on the reverse causality : What stimulates the
attractivity of academic research for private funding ? What is meant here by
contractual funding is all the funds received on a contractual basis, including
grants. Typically, all funds received from private sources are included while
recurrent public funding is excluded.
The main originality of our study is that it is micro-based, i.e. conduced
at the academic research laboratory level while the literature on academic
funding focuses on the university level of investigation. The laboratory is
emphasized as the relevant level of analysis of scientific activity (Crow and
Bozeman, 1987) especially in the Continental European style of academic
research organization and as long as funding issues are concerned (Stephan,
Our data allows us to examine three series of influences.
i) Publication signaling : Funds managers are subject to high uncertainty
and asymmetries of information on academics. In such a situation (adverse
selection), they may use publications to better evaluate laboratories compe-
tencies in specific domains, the quality of their scientific production or even
their ability to collaborate with industrial partners.
ii) Crowding : An important literature in public economics aims to evi-

dence the eﬀects of public funding on other sources for non profit institutions.
While theoretical models diﬀer in their predictions, Connolly (1997) shows
that external funding and internal support of US universities research crowd
in mutually and Payne (2001) finds that federal research funding of US uni-
versities crowds in simultaneous private donations.
iii) Matching : The characteristics of laboratories also may have a great
influence on private funds managers and on laboratories’ own willingness to
provide the specific eﬀorts associated with getting such funds.
The next section presents the data and the methodology. Section 3 pre-
sents the results while the last section concludes.
Our data cover the period 1993-2000 and concern the research activity of
76 laboratories which belong to one single university, namely Louis Pasteur
University (ULP) of Strasbourg. This university is quite large, diversified,
has an old tradition of fundamental research and a long standing of scientific
excellence2. The Third European Report on Science and Technology Indica-
tors (2003) ranks it first among French universities in terms of impact and
For each laboratory, we have eight annual observations on the follo-
wing time-variant variables : Private contractual funding (PRIVF (it)), Pu-blic contractual funding (PUBF (it)), Publication performance (PPER(it)),Publication performance corrected for impact (PIMP(it))3 and two dummyvariables indicating whether at least one paper is coauthored with a re-
searcher employed by a private firm (INDUS (it)) or by a foreign institution
2 ULP researchers have received numerous scientific prizes (six Nobel prices and one
Field Medal). Active researchers count one Nobel laureate, eleven members of the Institut
Universitaire de France and eleven members of the French National Academy of Science.

(INTER(it)). Time-invariant variables relate to the personnel employed in thelaboratories4 : Number of full professors or researchers (SENIOR(i)), assistantprofessors or researchers (JUNIOR(i)), PhD students (PHD(i)), non resear-chers (administrative personnel, technicians and engineers) (NONRES (i)),number of national (NPOST (i)) and foreign post-docs (FPOST (i)).

where X = (X1 : X2) and Z = (Z1 : Z2). We assume that εit are iid N(0, σ2)
uncorrelated with both the explanatory variables Xit and Zi. Following Haus-man and Taylor (1981) - hereafter HT -, Amemiya and MacCurdy (1986) -
hereafter AM - we assume that the individual eﬀects αi are iid N(0, σ2 ) cor-
related with X2 and Z2, uncorrelated with X1 and Z1. For estimating theequation (2), we use the Instrumental Variable (IV) method described in HT
In Table 1 (columns 1 and 2) we consider, first, the conventional proce-
dures Within and GLS estimates. The Within estimates are unbiased whether
or not the eﬀects αi are correlated with the explanatory variables5. Howeverthe GLS estimates are biased if the individual eﬀects are correlated with some
explanatory variables. The assumption that αi are uncorrelated with (X, Z)

is rejected in a Hausman test of the diﬀerence between the GLS and Wi-
thin estimates. The Hausman test is χ2 = 21.55 which is significant at 5 per
cent level. The HT and AM estimates are presented in columns 3 and 4. In
this regression we let X1 =(PUBF, INDUS, INTER), X2 =(PPER, PIMP),Z1 =(PhD, JUNIOR, SENIOR, NONRES ) and Z2 =(NPOST, FPOST ).
The set of instruments proposed by HT is legitimate and supported by a
Hausman test of the diﬀerence between the Within estimator and the HT
estimator. This test is χ2 = 0, 32 and is insignificant at five per cent le-
vel. Similarly, the additional exogeneity restrictions allowed by AM are not
rejected6. The Hausman test which compares AM and HT is χ2 = 2, 22.
Our first result shows that present public contractual funding coeﬃcient
is negative and significant. This supports the crowding out hypothesis. Nei-
ther the dummy for international collaborations, nor the one for industrial
collaborations are significant. It may indicate that such signals are either
not used by private funds managers or ambiguous. The level of publication
performance has a positive and significant eﬀect (as in Payne, 2003). The la-
boratories that publish more are more attractive in the eyes of private funds
The coeﬃcient of publication performance corrected for impact is nega-
tive. This result may seem counter-intuitive at first glance since the impact
factor of scientific journals may signal the quality of research. Nevertheless,
other phenomena seem to be predominant here. Let us suggest two of them.
First research appearing in the most prominent journals is likely to be more
fundamental while private contractual funding may seek research closer to ap-
plications. Secondly contracts with private partners often generate dedicated
and specific eﬀorts from faculty members (ex ante for attracting funds and
ex post for meeting the requirements). Laboratory managers may consider
the opportunity costs of contracts which are not independent of laboratory
characteristics. The alternate use of their time and eﬀorts in the academic

sphere is better valued by the ones who are publishing in the best ranked
journals (Carayol, 2003 finds similar results).
We now turn toward the eﬀects of labor force composition. Post-docs ef-
fects are positive and significant (the coeﬃcient for the domestic ones is three
times higher). This indicates that they strongly contribute to the research
eﬀorts implied by contracts signed with private partners. The coeﬃcient for
PhD students is also positive but significance is much lower : They are less
intensively involved in contractual research being also strongly driven by doc-
torate accomplishments. The eﬀect of non researchers is also positive : Suﬃ-
ciently large administrative and engineering staﬀ are important for attracting
interest and/or for meeting requirements (organization, delays, instrumenta-
tion, etc.). Associate professors and researchers are negatively correlated with
private funding : Not yet promoted researchers tend to concentrate on pure
academic work because of career concerns.
The paper proposes an analysis of the yearly arrival of private contrac-
tual funding of academic laboratories. We find that contractual public fun-
ding crowds out simultaneous private funding. Private funds are attracted
by the most active laboratories within the academic sphere while best ran-
ked publishing laboratories attract less. Post-docs increase private support
substantially because of “who is doing the job” issues.
