1 Measuring differences in public service motivation between the public and private sector Paul A. Grout 17 th November 2006 Centre for Market and Public Organisation

2 2 Two connected pieces of ongoing research on donated labour/public service motivation (both joint work) Quick summary of theoretical model of not- for-profit in a bureaucratic environment Evidence on donated labour from British Household Panel Survey

3 3 Not-for-profit in a bureaucratic environment

4 4 Donated labour: Private sector difficult to supply donated labour because of residual claimant expropriates the effect of donated labour Not-for-profit is able to provide an environment that favours donated labour because of the non-distribution constraint. Public sector? – bureaucratic environment

5 5 Three organisation stories Uni. Dept. NGO Marketised example

6 6 Parties Worker - paid w - chooses e: donated labour (non-contractible) - cares about output Outside agent - makes contribution of q to organisation Third party distant outsider

7 7 Output and pay-offs Output/quality: v(e,(1-t)q,w) Worker welfare: v(e,(1-t)q) – c(e) + w c(e) - convex c(0) = 0

8 8 Outside agent v(e,(1-t)y,w) – k(q) k(q) - convex k(0) = 0 [Third party v(e,(1-t)y,w) – k T (q)]

9 9 Time line Worker offered wage Worker makes e Outside agent offers of q Managers accepts or rejects If reject wait for non-stochastic arrival of q m

10 10 Single outside agent Suppose single outside agent - then their contribution is q s :

11 outcome with single outside party S

12 12 Introduce third party Introduce third party - their contribution would be q m :

13 outcome with third party T

14 14 Elasticity condition for all e

15 15 Proposition If the elasticity condition holds, then there is a unique θ, θ*, such that (i) (ii)

22 22 Preliminary Conclusions Empirical evidence supports basic the theoretical literature that donated labour is sensitive to organisational/ownership. Suggests not-for-profit may have a role to play in public service delivery However, bureaucratic structure may make donated labour delicate in this environment.
