Determinants of food security in Southern Ethiopia at the household level

In the early 1980s, a paradigm shift occurred in the field of food security, following Amartya Sens (1981) claims that food insecurity is more of a demand concern, affecting the poor's access to food, than a supply concern, affecting availability of food at the national level. Despite the wide acceptance of Sen's thinking, many controversies including the relative importance of supply‐side versus demand‐side variables in causing and solving food insecurity have remained in academic and policy circles. This study develops a recursive household food security model within the framework of consumer demand and production theories following Singh et al. (1986) , and parses out the relative importance of supply‐side versus demand‐side variables in determining household food security in southern Ethiopia. Based on results of a test of full/reduced model and the magnitude of changes in conditional probabilities of food security, we conclude that the supply‐side variables are more powerful determinants of food security than the demand‐side variables.     

The contingency effects of environmental uncertainty on the relationship between supply chain integration and operational performance

This paper extends prior supply chain research by building and empirically testing a theoretical model of the contingency effects of environmental uncertainty (EU) on the relationships between three dimensions of supply chain integration and four dimensions of operational performance. Based on the contingency and organizational information processing theories, we argue that under a high EU, the associations between supplier/customer integration, and delivery and flexibility performance, and those between internal integration, and product quality and production cost, will be strengthened. These theoretical propositions are largely confirmed by multi-group and structural path analyses of survey responses collected from 151 of Thailand's automotive manufacturing plants. This paper contributes to operations management contingency research and provides theory-driven and empirically proven explanations for managers to differentiate the effects of internal and external integration efforts under different environmental conditions.     

The core-customer concept

The purpose of this paper is to define and discuss the core-customer concept. This concept examines how a company develops its operations around a single or only a few customers. The customer steers what products and services the supplier develops, which means that it is the customer that dictates the supplier's operations. The core-customer concept may be one method for designing a company's operations, but the paper also aims to challenge companies to consider how they think about customers. The paper contributes to research on customer value and extended service offerings by indicating a business-development strategy based on the customer rather than the supplier's operations. Building a company around a single customer, requires flexibility and competences in finding collaboration partners or in adjusting the organisation to new requirements. The paper refers to these as secondary/supporting competences, while the core competence upon which the company builds its operation is the customer.     

The Influence of Legal Capacity on WTO Dispute Duration

World Trade Organization dispute settlement has evolved away from the concise process originally imagined to one where panels languish for years. This is to the detriment of lesser-developed states that do not have the resources that allow for access. In this article, I perform a multivariate analysis to explore the relationship between a state's legal capacity and the length of trade disputes. Controlling for selection bias, I find that the legal capacity of both of the involved parties contributes to longer disputes. The relaxed time expectations in this process favor the inclusion of developed states and exclude those without the resources necessary to carry out what has become the normal dispute process.     

Working Weeks,Rave Weekends: Identity Fragmentation and the Emergence of New Communities

Popular music is one of the most ubiquitous forms of contemporary culture. This paper looks at the phenomenon known as rave or dance culture in Britain. It examines the nature of the consumer experience at a dance club through the use of a two stage methodology. Based on observations and the collection of phenomenological data, the findings suggest that the experience is linked to a series of behaviours, which are related to fragmentation and identity. These include narcissistic identity, the emergence of new communities, the need for escape, engagement and prolonged hedonism. The paper examines these concepts in relation to postmodern consumption. In particular, an evaluation of postmodern theory and its focus on fragmentation and the project of the self is offered, by arguing for a return to "community".     

Identification and the narrative approach: A reply to Leeper

Contrary to the arguments of Leeper (1997), the problems that arise in VAR investigations of monetary policy do not arise with our use of the narrative approach. The apparent high predictability of our monetary-policy variable that Leeper finds is due to overfitting. And the estimated effects of our measure when variables other than output are considered are unsurprising given Leeper's specifications.     

Pricing behavior in United States manufacturing industries: A statistical study using disaggregated data

We investigate the relationship between industrial market structure and price flexibility (the administered-pricing hypothesis) across United States manufacturing industries by embedding market-structure variables in a model relating relative price variability (dispersion) and inflation. While we find support for a positive relationship between variability and inflation, we do not find that high seller concentration lessens the impact of inflation on price variability. We do find that the larger the efficient-sized plant, the lower the impact of inflation on variability. We also find strong effects of input prices and degree of product durability on relative price variability.     

Alterations in export patterns through transforming policies in Romania

This study examines Romanian export flows in light of the dismantling of the traditional economic ties within the former Eastern European trading bloc (the Council for Mutual Economic Assistance) and the conclusion (in 1993) of the Association Agreement between Romania and the European Union. These have led to a significant adjustment of the geographic trade pattern for Romania. The structural gravity model was employed to analyze the evolution of Romanian export flows to the two groups of main trading partners, i.e., the European nations of the former Council for Mutual Economic Assistance and the European Union. The empirical results support the view that the European Union became and will remain the major market outlet for Romanian exports in the following years.The authors are indebted to the participants of the 41st Atlantic Economic Conference for their helpful comments and suggestions on a first draft of this paper.     

The Effective Tax Burden of Companies and of Highly Skilled Manpower: Tax Policy Strategies in a Globalised Economy*

Company taxes and taxes on highly skilled labour both influence the attractiveness of a particular region as a location for investment. We measure the effective tax burden on capital investment and on highly qualified labour in 33 locations across Europe and the United States. We then correlate both types of tax burden in order to study the different tax policy strategies applied in different countries. We find that effective tax rates on companies and on highly skilled employees are closely correlated for a number of countries. Ireland and most new EU Member States impose relatively lower taxes on capital investment than on highly skilled manpower. Conversely, in the US, companies are taxed heavily but the effective tax rate on highly skilled employees is moderate.
