differentiate between growth in govt
expenditure vs. growth in govt's share
in overall economy
Increased govt expenditure since 1950's; growth stabilised since 1990's
Macro theories
Wagner
stages-of-development approach
govt grows as economy moves from traditional to industrial
first stages
capital investment in esp. infrastructure
put legal & administrative institutions
in place to decrease transaction costs
e.g. property rights
middle stages
capital investment still high
correct market failure that arises
from increased econ activity
last stage
capital expenditure by govt as proportion of GDP decreases
Increased expenditure on education,
healthcare, welfare security, social services
from here, govt share in economy decreases continuously
Peacock & Wiseman
displacement effect
size of govt largely determined by
political events, e.g. wars, elections
political events that require large
expenditure increase the size of govt
creation of interest groups/ getting used to
high expenditure and tax means govt doesn't
shrink to original size after the political event
Meltzer-Richard hypothesis
general equilibrium model: govt size
as function of majority voting
NB of median voter in determining size of govt
"decisive voter"
extention of franchise most NB
determinant of share of govt in
economy
pressure on govt comes from
where income of median voter
lies in relation to average income
if below = pressure on
govt to redistribute
income
only works if you assume voters are aware of disincentive effects of high
taxes and redistribution, i.e. median voter will choose tax rate that maximises
her utility SUBJECT TO the impact the rate will have on the behaviour of other
econ actors
Micro theories
Baumol
unbalanced productivity growth
progressive vs non-progressive sectors
progressive large technology absorption capacity
increase in labour productivity as new technology is adopted
non-progressive reliant
on labour, e.g. medicine
ceiling on labour productivity
increases due to new technology
public sector wages must remain
competitive with private sector
increased wages in public sector due
to increased labour productivity in
private sector
Brown & Jackson
service enviro explanation
explain demand and supply
for public goods and services
demand a function of
income of median voter
preferences of
median voter
tax on median voter
supply a function of
costs of production
Role of politicians,
bureaucrats & other
interest groups
