Constructing KHTs

Example: Flood Control and Navigation Project

•Flood Control

•Navigation Improvement

Question: What should accounting domain be?

Answer: Philosophic question without a definitive answer.

Recommendation: Use KHTs to represent projectsat multiple accounting domains

Aggregation Issues

•Relevance of Stakeholder Effects;

Is the stakeholder group significantly affected, i.e., net effect > 0?

Is the welfare of the stakeholder group particularly policy relevant?

If yes to both questions, useful to show stakeholder column explicitly

• Information constraints

EXAMPLE: Representing Labor Market Impact

•Useful to represent labor. Impact significant, and policy relevant

•Useful to represent agencies for same reason

EXAMPLE: Representing Labor Market Impact

•Not as useful to represent labor explicitly. Impact not as significant, and not as policy relevant. i.e., employment level does not change when workers displaced from one occupation to another, and impact is less significant than going from unemployment to employment, as in KHT1.

•KHT2 derived from KHT1 by aggregating (2) and (3) in KHT1

•Still useful to represent agencies

KHT 2Low unemployment (tight labor market)

KHT Disaggregated Across Backward Linkages

Backward Linkage Disaggregation Continued

Under idealized assumptions, perfect competition, no market distortions or externalities, P=L1+L2+L3+L4+C+L5

Explanation. By the assumption of zero excess profit, net cells for all input suppliers sum to zero, implying:

E4=(C+L5); E3=(E4+L4); E2=(E3+L3); E1=(E2+L2); P=(E1+L1).

Recursive substitution gives:

E4=C+L5 into E3=> E3=L4+C+L5

E3=L4+C+C5 into E2=> E2=L3+L4+C+L5

E2=L3+L4+C+C5 into E1=>L2+L3+L4+C +L5

E1=L2+L3+L4+C +L5 into P=>P=L1+L2+L3+L4+C+L5

Implications

*As a default, project expenditure can be taken to represent costs. Thus, as a default, the benefit of a project can be compared against its expenditure=cost.

*However, if there are market distortions (taxes/subsidies) or externalities we must “shadow price” -- adjust expenditures to reflect costs.

*In theory, this adjustment should be done at every step of the supply chain – as in “life cycle assessment” of environmental impacts.

*In practice, “shadow pricing” in BCA is usually conducted just at the first step of the supply-chain.

KHTs in Market Applications

KHT Format can be applied to common

partial-equilibrium market applications

Rationale for using KHTs

•Efficient Display Format: a KHT gives in one integrated assessment the Kaldor-Hicks accounting and conventional BCA input-output valuation (in its boundary rows and columns), as well as the project’s distributional effects/stakeholder impacts, including the project’s fiscal effects.

•Transparency: clearly shows stakeholder effects, and accounting domain assumptions.

• Distributional assessment: for

-- stakeholder participation

-- political implications (positive assessment of political impacts)

-- normative judgments about income distribution or other stakeholder effects
