Abstract
The oil cartel’s activity causes distortions of the oil industry structure resulting from the spatial misallocation of production. In the long term, production shifting from the low-cost cartel to the high-cost competitive fringe brings about a misallocation of global oil resources. In this chapter we consider a two-region model of resource extraction with investment in reserves development, in which the global allocation of oil resources is determined endogenously. We show that if the cartel’s advantage in production costs over the competitive fringe is considerable, the distorting effects of the cartel are substantial, and the efficiency losses on the industry level may be significant. The cartel captures a part of consumer benefits at the cost of significant losses from resource misallocation and deadweight losses. These losses, however, can be reduced due to technological changes improving the competitiveness of the fringe.
This chapter is based on the unfinished paper by Barry Ickes and Georgy Trofimov.

1.1 A.1 Condition (10.20)
Investment in creation of the initial reserve stock is
since ξa = xa/δasa and due to (10.11). From Eq. (10.18), the firm’s net present value (10.19) is
1.2 A.2 Equations (10.27), (10.28)
From Eqs. (10.22), (10.24), the first-order condition for the cartel is:
We use the fact that ∂Pt/∂xAt =  − 1/(μ + δbsBt) and rearrange the left-hand side:
This yields (10.27).
Consider Eq. (10.28). From Eqs. (10.8), (10.27), the supply functions are:
Inserting these functions into the market-clearing condition (10.3) implies the equation for Pt:
because \( {\delta}_j{s}_{Jt}={\sigma}_{Jt}{E}_t^C \) for J = A, B, D = αμ. This equation can be rewritten as
and the market-clearing cartel price is equal to
1.3 A.3 Proposition 10.2
The cartel price Eqs. (10.30) and (10.31) are compatible if σA satisfies:
or 1 − σA = ξa/(ξb + zb − za), implying (10.33):
since ΔP = Δξ + Δz, where Δξ = ξb − ξa, Δz = zb − za.
Equation (10.31) is compatible with (10.32) represented as
if the following equation is fulfilled:
Rearrange both sides:
or, since σD = 1 − σA − σB,
From Eq. (10.31), ξa = (1 − σA)(P − za), hence
We have:
due to (10.33) and since p = ξa + za.
Consequently
1.4 A.4 The Pure Monopoly Case
Equating the right-hand sides of Eqs. (10.31′) and (10.32′) yields the following equation on σA:
Rearrange the terms:
and obtain:
1.5 A.5 Proposition 10.3
We have it from condition (10.29) that ξJ = xJ/δjsJ = ξj implying that xJ = δjsJξj for J = A, B and j = a, b. This yields xJ = (σJ/σD)μξj because σJ = δjsJ/EC and σD = μ/EC.
1.6 A.6 Equations (10.41), (10.42)
The cartel value in period 0 is VA = r−1πA − zasA. Since xA = δasAξa and from Eq. (10.29) we have:
Hence
because, from Eq. (10.33),
Equations (10.50), (10.29) imply that
This means that the initial investment by the cartel equals the present value of the cartel’s net competitive profit shown by triangle zapG in Fig. 10.5.
1.7 A.7 Equation (10.44)
The loss of consumer surplus due to cartel pricing is
From Eqs. (10.42), (10.51) and (10.3):
From Eq. (10.38), −ΔxA = xB − ΔD and, consequently, ΔWC =  − (2xB − ΔD)ΔP/2r =  − (xB + (μ/2)ΔP)ΔP/r =  − (xBΔP + (μ/2)(ΔP)2)/r, since −ΔD = μΔP.
1.8 A.8 Equations (10.47)–(10.49)
From Proposition 10.2, the demand share is
Equations (10.42), (10.39), (10.33), (10.52) imply that
From Eq. (10.21), W = μ(α − p)2/2r, hence
From Eqs. (10.45), (10.34), (10.39), (10.52) we have it that
Consequently
From Eqs. (10.46), (10.21), ΔW2 =  − μ(ΔP)2/2r and
