Using Calvo-type price adjustment, Woodford (2003) shows that the aggregation of the linearized optimal price adjustment rules for the individual firms yields an expression in current and expected future inflation and a measure of aggregate
marginal cost, mc,
According to this Hybrid NKPC current inflation is determined by output gap (or real
marginal cost), previous period's inflation and future expected inflation.
In many cases
marginal cost is either theoretically

Marginal cost and R&D expenditure, symmetric duopoly
The key feature of those models, which we focus on directly here, is the assumption of constant
marginal cost, which allows domestic and foreign markets to be treated as independent markets in the analysis.
Their risk perception is higher in the current market scenario," says a private sector banker.A year ago, the RBI's own working group on pricing of credit had talked about the difficulties in shifting to the
marginal cost of funds.
If firms in the competitive sector are similar, the price charged to final users ends up equal to the
marginal cost of each firm.
The MNE prefers to employ only one transfer price, and as in Regime 3 it incurs costs of transfer pricing to the extent that the chosen transfer price deviates from its
marginal cost. In essence, tax authorities again desire to see the transfer price computed according to the "cost-plus method", implying that the MNE needs to spend resources to defend a differing transfer price.
One of the over-arching themes in these studies is the high economic cost of departures from
marginal cost pricing.
Similarly to Giokas (1997), we also employ a combination of two models (stages) to determine a supplier's
marginal cost. As mentioned above, our approach is based on the fact that e-RA bids reveal some information about the suppliers'
marginal costs (Zhang and Jin 2007), which may enhance the knowledge base of
marginal costs beyond that introduced in previous research.
Inspired and motivated by the above results in this research field, in this paper, we establish two duopoly game models of product quantity and the water supply for two firms to produce differentiated product under the settings of complete information and incomplete information, respectively and obtain the corresponding allocation results of product quantity and the water supply under the condition that the market power exists, and next, we compare the allocation results obtained under the setting of incomplete information on
marginal cost with that obtained under the setting of complete information on
marginal cost.
