In this paper I analyse the strategic interaction of decision makers and their advisers in a consultation process. I find that when agents are concerned about their reputation, consultation results in sub-optimal sharing of information; some decision makers may deliberately act unilaterally and...

The Wong-Viner Envelope Theorem on the equality of long-run and short-run marginal costs (LRMC and SRMC) is reformulated for convex but generally nondifferentiable cost functions. The marginal cost can be formalized as the multi-valued subdifferential a.k.a. the subgradient set but, in itself,...

In this paper, we build and structurally estimate a complete information bargaining model of collective negotiation for Spain. For large firms, the assumption of complete information seems a sensible one, and it matches the collective bargaining environment better than the one provided by...

Using convex calculus, we extend the Wong-Viner Theorem to nondifferentiable costs by equating the capital inputs' rental prices to their profit-imputed marginal values. Thus extended, the short-run approach to LRMC pricing is applied to peak-load pricing with storage

The quot;short-run approachquot; calculates long-run producer optima and general equilibria by building on short-run solutions to the producer's profit maximization problem and on profit-based valuation of the fixed inputs. We outline this method and illustrate it on an example of peak-load pricing

Duality methods of linear and convex programming are applied to impute definite marginal values to the fixed inputs of a hydroelectric plant from the operating profit. Our earlier analysis of pumped storage (of energy and other cyclically priced goods) is thus extended to valuation of an...

This paper introduces two complementary models of firm-specific training: an informational model and a productivity-enhancement model. In both models, market provision of firm-specific training is inefficient. However, the nature of the inefficiency depends on the balance between the two key...

We study the evolution of prices in a symmetric duopoly where firms are uncertain about the degree of product differentiation. Customers sometimes perceive the products as close substitutes, sometimes as highly differentiated. Firms learn about their competitive environment from the quantities...

With L as the commodity space, the equilibrium price density is shown to be a continuous function of the commodity characteristics. The result is based on symmetry ideas from the Hardy-Littlewood-Poacute;lya theory of rearrangements; and it includes, but is not limited to, the case of symmetric...
