This paper attempts to evaluate the possible gains and losses arising from the gradual opening up of pharmaceutical trade between India and Pakistan. We explain the comparative advantages of both countries at a disaggregated level, followed by a qualitative analysis of various perceptions and...

We develop a product-differentiated model where the product space is a network defined as a set of varieties (nodes) linked by their degrees of substitutability (edges). We also locate consumers into this network, so that the location of each consumer (node) corresponds to her "ideal" variety....

This paper analyzes price collusion in a repeated game with two submarkets; a standard and a premium quality segment. Within this setting, we study four types of price-fixing agreement: (i) a segment-wide cartel in the premium submarket only, (ii) a segment-wide cartel in the standard submarket...

Today, the global pharmaceutical product value chain is becoming increasingly complex and this has led to the emergence of 'multiple quality standards' for medicines. But this non-uniformity in the quality of medicine is also contingent upon both the regulatory milieu in the country of...

The auto sector in Pakistan has been a persistent opponent of trade liberalisation in the country. This has entailed losses to consumers in terms of higher prices, low safety and quality standards, and lack of innovation in this sector. The deletion programme, which was to result in...

Increasing environmental awareness may affect the pleasure of consuming a good for which an environmental friendly substitute is available. When deciding to buy differentiated products, a compromise is sometimes made between preferred characteristics of the good and its environmental properties....

This paper develops a two-country, general equilibrium model of oligopoly in which the degree of horizontal product differentiation is endogenously determined by firms strategic investments in product innovation. Consumers seek variety and product innovation is more skill intensive than...

In this paper, we tackle the dilemma of pruning versus proliferation in a vertically differentiated oligopoly under the assumption that some firms collude and control both the range of variants for sale and their corresponding prices, likewise a multiproduct firm. We analyse whether pruning...

In this paper we extend the model of vertical product differentiation to also consider information disparities about the extent of quality differences. Equilibrium prices turn out to depend not only on the share of informed consumers but also on uninformed consumers beliefs about quality...
