The Role of the State

LSE 400
Context
• The 20th century saw a radical change in the role of the state around
the world
• Increases in tax raising from around 10% of GDP to around 40% in some
countries
• Expansion of public programs
• Health care
• Pensions
• Education
• The same period saw more or less sustained increases in material
living standards (economic growth)
• Much debate about whether the state is a drag on growth.
• But much more about the form than the level of intervention
Issues
• How should we think about the role of the state?
• market supporting role
• Regulation
• Contract enforcement
• Competition policy
• market augmenting role
• Health care
• Education
• Social security
Approaches
• Economists have traditionally approached this as a technocratic problem
• theory and data combine to advise how to intervene and in what way
• cost benefit at the heart of policy advice
• this has given economists a seat at the policy table
• The perspective is shamelessly normative
• The grand Utilitarian tradition
• But recent approaches have shifted this perspective relying in some cases on
taking a broader perspective
• greater focus on policy implementation
• debating the role of politics
• not just as a nuisance
• paying more attention to determinants of state capacities and where they come
from
• requires looking at history and broad comparisons
This Presentation
• Discuss the standard technocratic approach and its influence
• Reasons for pushing back on the approach
• Reframing the issues through thinking about state capacities
• Concluding comments
The Case for Intervention
• The dominant view looks at problems of market failure
• example: basic sanitation
• observation that markets do not automatically result in investments to manage clean water
and disposal of waste
• problem of externalities since benefits accrue partially to others
• requires a state to "fix the problem"
• could be subsidies or direct provision
• How much provision?
• what is the cost of sanitation projects?
• how to value the benefits?
• willingness to pay?
• or could be indirect measures of economic benefits (e.g. evidence from asset markets)
• evidence from randomized trials
• Core approach used by the World Bank and UK Treasury for a variety of public
projects
Example of Evidence from an Asset Market
Concerns
• Measurement
• how effective is the quantification?
• some aspects very hard to measure and then not taken into account?
• are valuations universal?
• how context specific and how immutable?
• Implementation
• Can quantify benefits of an ideal project.
• but is there any guarantee that projects will be implemented?
• what if there are corruption problems?
• how can projects respond to new evidence and developments?
• It is tempting to believe that this should make us more cautious about
intervention
• but can projects shift the political equilibrium (Bolsas Familias)
The Idea of State Capacity
• Three dimensions
1. Legal capacity
2. Fiscal capacity
3. Collective capacity
• Such capacities vary greatly across economies and over time
• The twentieth century saw a transformation in state capacities
Where do state capacities come from?
• Economic determinants
• Common factors that drive growth and prosperity
• Human capital
• Inequality
• Fractionalization
• Political determinants
• Institutions which affect
• Use of power
• cohesiveness
• Acquisition of power
• Stability
• Cultural determinants
• Norms of cooperation

Why useful?
• Begins by asking about the role of the state based on what states actually
do and how they do it
• (positive economics)
• Uses this to think about what states ought to do but respectful of the need
to have effective state action
• (normative economics)
• Blending insights from history and wider disciplines
• "when we pass ... to problems of taxation, or problems that concern the relations of
the State with trade and industry, or to the general discussion of communistic and
socialistic schemes -- it is far from being the case that economic considerations hold
the field exclusively. Account must be taken of the ethical, social, and political
considerations, that lie outside the sphere of political economy regarded as a
science." (John Neville Keynes [1891, page 55], The Scope and Method of Political
Economy)
Reflections on Policy Debates about State
Intervention
• Enhancing state capacity lies behind many policy debates about state
intervention:
• Affects thinking about foreign aid
• Does it enhance or compromise building state capacity?
• Thinking about supra-national action
• Fiscal and collective capacity beyond the nation state
• International pressure to to enhance state effectiveness (TI, EITI, Benchmarking)
• Do they lead to more state capacity?
• Decentralized versus centralized states
• Debates about devolution in the UK are about the locus of state capacity
• Link to state building and political violence
• How states establish and maintain law and order can influence state capacity building.
Is politics a nuisance?
• Largely ignored in most policy economics
• Exception was the public choice tradition (highly normative)
• Second best theory of politics
• Politics should be studied so that we can navigate around it
• First best theory of politics
• Politics is why things happen (for better or worse)
• Study politics and incorporate it into policy analysis to understand how make
things work better
• Leads to a natural focus on institutions and structures that influence policy choice and
policy implementation
• Expands the scope of economics even further!
