Abstract: Traceability can be studied from different viewpoints. In this paper, we analyze it as a management tool whose implementation implies organizational changes for the firm, but via which improved competitiveness may be realized. More specifically, the aim of this paper is to analyze the evolution of traceability management topic over the past twenty years (1994-2014) through a literature review, to identify the related concepts and settings that have been considered, and further, to delineate possible research gaps in the literature. To achieve this objective we created a self-assembled database, which permitted us to carry out a descriptive analysis of papers and to derive relevant conclusions and different implications for the future. We found that the concept of traceability as a tool to improve organizational performance has gained legitimacy and consequently is now widespread. Hence, traceability is treated from different areas of the firm embracing implementation, control, information systems, consumers' opinion or supply chain. Additionally, we believe that traceability research has to progress furthermore so as to dismantle its sturdy focus on the food industry because traceability management can be meaningful for broad sectorial applications. This study contributes to the traceability body of literature as it permits defining the trends about this research field and it represents an orientated guide to enrich traceability studies in topics associated to business organizations.2015-01-01T00:00:00ZQuality differences, third-degree price discrimination, and welfarehttps://hdl.handle.net/10171/431152020-03-04T02:27:42Z2015-01-01T00:00:00ZTitle: Quality differences, third-degree price discrimination, and welfare
Abstract: We propose a theoretical model to analyze the welfare implications of price discrimination in the presence of differences in quality. The model considers two markets where in each market competition takes place between a local firm that operates in that market only and a global firm that operates in both markets. All firms are assumed to be producing with zero marginal costs. Local firms produce a good that is perceived by consumers to have superior quality than that produced by the global firm. We find that there are parameter values such that welfare increases while total output decreases if the global firm engages in price discrimination. This is due to a positive allocation effect brought about precisely by the global firm engaging in price discrimination.2015-01-01T00:00:00ZExploring the oil prices and exchange rates nexus in some African economieshttps://hdl.handle.net/10171/431102020-03-03T13:48:37Z2015-01-01T00:00:00ZTitle: Exploring the oil prices and exchange rates nexus in some African economies
Abstract: This paper investigates the relationship between oil prices and exchange rates in three African countries using a Vector AutoRegressive (VAR) model. We use daily dataset on nominal exchange rates, oil prices and short term interbank interest rates from 01/12/2003 to 02/07/2014. The results suggest that the exchange rate of three selected countries displayed differing in the event of an oil price shock, not only before and after the oil peak of July of 2008, but also between each other, implying that no general rule can be made for net oil importing sub-Saharan countries, such as Botswana, Kenya and Tanzania. From our analysis we conclude that after an oil price peak, the Botswanan pula clearly appreciates against the US dollar, the Kenyan and Tanzanian shilling.2015-01-01T00:00:00ZPublic Goods in Endogenous Networkshttps://hdl.handle.net/10171/431062020-03-03T13:50:49Z2015-01-01T00:00:00ZTitle: Public Goods in Endogenous Networks
Abstract: In this paper, we study a local public good game in an endogenous network with heterogeneous agents. We consider two specifications in which different networks arise. When agents differ in the cost of acquiring the public good, active agents form hierarchical complete multipartite graphs; yet, better types need not have more neighbors. When agents' benefits from the public good are heterogeneous, nested split graphs emerge in which investment need not be monotonic in type. In large societies, few agents produce a lot and networks dampen inequality for most agents under cost heterogeneity and increase it under heterogeneity in benefits.2015-01-01T00:00:00Z
