The effect of spot and futures trading on stock index market volatility: A nonparametric approach

This article provides empirical evidence on the intraday relation between spot volatility and trading volume in the Spanish stock index futures market. GARCH methodology is used to estimate spot volatility. We analyze the potential relation between spot and futures trading volume and spot volatility by estimating the corresponding conditional density functions as proposed in Quah (1997). Our results reveal no significant link between those variables. Similar findings arise when expected and unexpected volume is considered. Our results suggest that derivative market is not a force behind episodes of significant spot jump volatility. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:841–858, 2003     

B‐TO‐B E‐COMMERCE: A CONTENT ANALYTICAL ASSESSMENT OF MOTOR CARRIER WEBSITES

An Internet presence is a critical early component in the process of building towards a fully operational and unified e‐commerce strategy. E‐commerce has significantly impacted logistics/supply chain strategies and the development and implementation of a website have become key issues for many firms within the transportation industry. This study provides an overview of website content within the motor carrier industry. Content analysis was used to assess the site design, informational content, and the interactive content of 152 motor carrier websites, and to compare the features offered on the Top 100 motor carrier firm websites with those offered on the sites of smaller carrier firms.     

PLANNING MULTIPLE LOCATION INVENTORIES

Supplying customer demand from comparable alternate inventory locations when an item is out of stock at its primary stocking point creates a virtual inventory for that item. The expectation is that if more inventories can be drawn upon, the inventory for an item would be lower, the fill rate would be higher, or both. While generally true that safety stocks will be lower, regular stocks, on the other hand, may rise with such cross filling of demand. In this study, a methodology is developed that balances the cross filling effects on both regular and safety stocks for determining whether an inventoried item should be cross‐filled. An example and guidelines are given to show how the methodology can be simplified and applied in practice.     

RELATIONSHIP MAGNITUDE AND ITS ROLE IN INTERORGANIZATIONAL RELATIONSHIP STRUCTURE

Close relationships between and among supply chain members are becoming more prevalent. However, there is lack of agreement in the literature and in practice concerning the characteristics of different interorganizational relationships. The resultant confusion is an obstacle to the progression of research and could cause problems among firms in a supply chain. Based on previous research and an exploratory study conducted with company executives responsible for supply chain management activities, this article seeks to introduce the concept of relationship magnitude (i.e., the extent or degree of closeness or strength of the relationship) and differentiate it from relationship type (i.e., classes of relationships that share common traits). Implications for managers and opportunities for future research are provided.     

Coordinated strategies for economic cooperation between Europe and the United States

Zusammenfassung Koordinierte Strategien für wirtschaftliche Zusammenarbeit zwischen Europa und den Vereinigten Staaten. - In diesem Aufsatz wird die dynamische Spieltheorie auf die Koordinierung der Politik zwischen den Vereinigten Staaten und der EWG in einem stark aggregierten Modell angewandt und folgendes gezeigt: (i) Eine Politik, die den Einflu\ von Ma\nahmen anderer L?nder vernachl?ssigt, führt in den USA zu Fiskalischen Einschr?nkungen und einer Verminderung der staatlichen Interventionen, in Europa dagegen zu einer Nachfragestimulierung, verbunden mit einer kontinuierlichen Herabsetzung des Diskontsatzes. Die EWG-L?nder sind, da sie ihre Politik nicht koordinieren, nach einigen Jahren wegen Zahlungsbilanzschwierigkeiten zu einer kontraktiven Nachfragepolitik gezwungen. (ii) Koordinierte Strategien best?tigen, da\ nicht-synchronisierte Politiken die Weltwirtschaft stabilisieren k?nnen. (in) Kooperation verbessert die wirtschaftlichen Leistungen, ausgedrückt in den Wachstumsraten und den Zahlungsbilanzen. Allerdings erbringt die ausdrückliche Zusammenarbeit kaum noch zus?tzliche Vorteile zu denen, die bereits im Rahmen der vollen Koordinierung erreicht werden k?nnen.

Resumen Estrategias coordinadas de cooperación económica entre Europa y los EEUU.- La aplicación de un modelo dinámico de teoría de juegos a la coordinatión de política económica entre los EEUU y la CEE, como parte de un modelo altamente agregado de la economía mundial, permite concluír en este trabajo que (i) políticas que ignoran la influencia de medidas tomadas en otros países dan lugar a una contractión fiscal y a una menor interventión del Gobierno en los EEUU, pero a una estimulación de la demanda combinada con reducciones continuas de la tasa de descuento en Europa; al seguir políticas descoordinadas los países de la CEE están obligados a contraer la demanda agregada al cabo de unos a?os, debido a los problemas de balance de pagos, (ii) estrategias coordinadas confirman que políticas no sincronizadas pueden estabilizar la economía mundial; (iii) la cooperación favorece a la economía en términos de tasas de crecimiento y balance de pagos. Sin embargo, los beneficios adicionales de una cooperatión explícita resultan marginales en comparación con los beneficios ya alcanzados por la solución con coordinación total.

Résumé Stratégies coordonnées pour la coopération entre l’Europe et les E.U. - En appliquant la théorie dynamique de jeu à la coordination de politique entre les E.U. et la CEE dans un modèle fortement agrégé de l’économie mondiale, cet article arrive aux conclusions suivants: (i) La politique qui ignore l’influence des actions suivies dans d’autres économies mène à la réduction fiscale et à moins interventions gouvernementales dans les E.U., mais à une stimulation de la demande avec des réductions continuelles du taux d’escompte en Europe. En cas d’une politique pas coordonnée les pays CEE sont forcés à prendre des mesures pour freiner la demande agrégée après quelques années à cause des problèmes de la balance des paiements. (ii) La stratégie coordonnée confirme que des politiques pas synchronisées pourraient stabiliser l’économie mondiale. (iii) La coopération peut élever le taux de croissance et améliorer la balance des paiements. Cependant, les gains additionnels d’une coopération explicite sont petits en comparaison avec les bénéfices déjà gagnés à l’aide d’une solution complètement coordonne’e.

     

Migration as a Strategy of Accumulation: Social and Economic Change in Eighteenth-Century Savoy

Migration from the mountain areas of pre-industrial Europe has been seen as the product of poverty. While hardship controlled the strategies of the more marginalized households, better placed families used their migration experience to establish themselves in commerce. Over generations they used contacts and kinship systems to develop important informal trading networks. It is difficult to establish the effects of this hidden activity on local mountain economies, but dowry payments and post mortem inventories are used to expose the impact of inflowing capital and its circulation.
