This paper revisits the results of the pioneering models of the firm under demand uncertainty and analyses the apparent disparity with respect to the signal of the investment-uncertainty relationship predicted by them. In the 1970’s-1980’s the modelling of demand uncertainty at the firm...

We propose a new framework to analyse the wage premium behaviour. Building on Acemoglu and Zilibotti (2001), we introduce physical capital and two assumptions: (i) internal costly investment in both capital and R&D; (ii) complementarities between capital goods in production. We find that, for...

Although the conventional R&D-patents relationship is a long stand and relatively undisputed issue within the innovation literature, the reverse causality, in particular, the potential for a negative impact of patents over R&D has only recently received wide attention boosting interesting...

Existing illustrations of the learning phenomenon either stress the relationship between flows and stocks, neglecting the chronological time variable, or the speed of knowledge accumulation along time, neglecting the nature of the underlying learning process. In this paper we present a graphical...

In this paper, we evaluate the effect of demand uncertainty on hospital costs. Since hospital managers want to minimize the probability of not having enough capacity to satisfy demand, hospitals have to build excess capacity since demand is uncertain, and incur on the associated costs. Using...

This paper analyzes the impact of vertical integration on the static and dynamic stability of downstream incomplete collusion. It is shown that a vertical merger between an upstream firm and a downstream cartel or fringe firm promotes downstream collusion, under certain conditions on the market...

In this paper we compare two instruments of access price regulation, cost-based and retail-minus, with the full deregulation hypothesis. We consider an upstream monopolist firm that sells a vital input to an independent firm and to a subsidiary firm in the downstream market. We conclude that the...

A dynamic directional input distance function is proposed within the adjustment-cost model of the firm, generalizing the directional distance function developed by Chambers, Chung and Färe (1996) in the static context. Duality is established between the dynamic directional distance function and...

In the last decades there has been a gradual liberalisation of international air transport markets through the implementation of open skies agreements which seek the deregulation of the air transport industry and consequently the functioning of the market in a freer way. The objective of this...

This paper analyzes the location patterns of firms in Cournot spatial discrimination setting. The innovation step is that firms are allowed to have different marginal costs of the production. When analyzing the two-stage location-quantity game, we conclude that firms choose the central...
