Information transmission between the Gulf equity markets of Saudi Arabia and Bahrain

This paper examines whether the emerging Gulf markets of Saudi Arabia and Bahrain in conjunction with the US market exhibit cointegrating relationship. Additionally, the transmission of information and volatility spillover between the Gulf markets is explored using a bivariate EGARCH model. We find that although the markets are not cointegrated, the Gulf markets do share information flows. Specifically, we observe an asymmetric spillover of volatility from the smaller though more liberal and accessible Bahraini market to the larger and less accessible Saudi market. The observed difference in information processing may partly be due to a well-developed Bahraini financial sector that encourages wider participation by international investors who play a significant role in assimilating new information.

The Notching Rule for Subordinated Debt and the Information Content of Debt Rating

This paper provides new evidence regarding the information content of debt ratings. We show that noninvestment grade subordinated issues are consistently priced too high (the yield is too low), and the reverse is true for some investment grade bonds. We relate this empirical bias to a notching rule of thumb that is used in order to rate subordinated debt without expending additional resources for information production. We propose an explanation for these findings based upon a balance between an attempt to please the companies that pay the raters versus a concern for lawsuits and regulatory investigations should ratings be too optimistic.     

Inferences about the parameters of a time series model with changing variance

Summary We consider the problem of making inferences about the parameters of a time series model when there is the possibility of a discrete variance change at an unknown time point. For this we obtain the posterior distributions of the parameters and of the variance ratio.     

Communication skills in accounting education: Perceptions of academics,employers and graduate accountants

Communication skills are central to intellectual interaction between the providers and the recipients of information. The importance of accounting starts with the gathering and processing of information and ends with the communication of processed information. This paper examines the communication skills which employers, academics and graduate accountants consider necessary to the newly graduated accountant. It also identifies and considers the differences in perception which occur between these groups and suggests solutions to the communication gap. This study confirms findings from previous research that new graduate accountants experience communication-related problems in early employment. In addition, it provides evidence that the Australian accounting curriculum has contributed to the development of communication skills. However, the paper highlights the need for the reconsideration of an emphasis on communication skills in the accounting curriculum, a role which arises from the very nature of accounting as the processing and communication of information.     

The effect of globalization on union bargaining and price-cost margins of firms

In recent years, Europe has witnessed an accelerated process of economic integration. This paper analyzes how increased economic integration has affected labor and product markets. We use a panel of Belgian manufacturing firms to estimate price-cost margins and union bargaining power and show how various measures of globalization affect them. Import competition puts pressure on both markups and union bargaining power, especially when there is increased competition from low wage countries. This suggests that increased globalization is associated with a moderation of wage claims in unionized countries, which should be associated with positive effects on employment.

The impact of tariffs on profits in the United States and other major trading countries

Zusammenfassung Die Auswirkungen von Z?llen auf die Gewinne der Unternehmen in den Vereinigten Staaten und anderen gr?▾eren Handelsl?ndern. - In diesem Aufsatz wird das Michigan-Modell benutzt, um die Auswirkungen der Protektion auf die gesamten Gewinne und die Stückgewinne in den USA und anderen wichtigen Handelsnationen zu untersuchen. Es ergibt sich, da▾ die Protektion die Gewinne in den Exportsektoren st?rker verringert, als sie die Gewinne derjenigen Sektoren verbessert, die mit Importen konkurrieren. Allerdings bleiben die Gesamtgewinne aus der Kombination von exportorientierten und importsubstituierenden Unternehmen im allgemeinen von den bestehenden Z?llen unbeeinflu▾t. Au▾erdem finden die Gewinntransfers zwischen Exporteuren und importsubstituieren-den Unternehmen meistens innerhalb der gleichen Branche und nicht zwischen verschiedenen Branchen statt. Deshalb erh?hen allgemeine tarif?re Ma▾nahmen kaum die Gewinne von US-Industrien. Nur Tarife, die auf bestimmte Produktgruppen gerichtet sind, k?nnten derartige Wirkungen haben.

Résumé L’effet des droits de douane sur les profits dans les Etats Unis et des autres pays principaux commer?ants. - Dans cet article le modèle Michigan de production mondiale et de commerce est appliqué pour analyser l’effet de la protection sur les profits totaux et par unité dans les Etats Unis et des autres pays principaux commer?ants. Les auteurs trouvent que la protection réduit les profits dans les secteurs exportatrices plus qu’elle stimule les profits dans les secteurs en concurrence avec les importations. Cependant, les profits totaux des entreprises exportatrices et en concurrence avec les importations ensemble ne sont pas affectés par des droits de douane existants. De plus, la majorité des transferts des profits entre les entreprises exportatrices et en concurrence avec les importations se passe dans la même industrie au lieu d’entre des industries. C’est pourquoi, il est conclu que des mesures générales tarifaires probablement n’augmentent pas les profits des industries des E.U. Ce ne sont que les droits de douane sur des groupes des biens spécifiques qui exercent un tel effet.

Resumen El impacto de los aranceles sobre los beneficios en los Estados Unidos y otros países de importancia en el comercio international. - En este trabajo se utiliza el modelo de productión y comercio mundiales de Michigan para analizar el impacto de la protectión arancelaria sobre los beneficios totales y por unidad en los Estados Unidos y otros países de importancia en el comercio international. Los resultados indican que la protectión disminuye los beneficios en los sectores de exportatión y estimula los beneficios en las industrias que compiten con las importaciones, superando el primer efecto al segundo. Los beneficios totales de las empresas de exportatión y sustitución de importaciones juntas, empero, generalmente no son afectados por los aranceles existentes. Además, la mayor parte de la transferencia de beneficios entre exportadores y empresas de sustitución de importaciones tiene lugar dentro de la misma industria y no entre industrias diferentes. Por ello, medidas arancelarias de tipo general no son susceptibles de mejorar los beneficios de las industrias de los EE UU. Solamente aranceles que afecten a determinados grupos de productos podrían tener ese efecto.
