Consumption Externalities,Coordination, and Advertising*

The aim of this article is to demonstrate that advertising can have an important function in markets with consumption externalities apart from its persuasive and informative roles. We show that advertising may function as a device to coordinate consumer expectations of the purchasing decisions of other consumers in markets with consumption externalities. The implications of advertising as a coordinating device are examined in the pricing and advertising decisions of firms interacting strategically. Although, at times, the one‐period advertising expense can exceed the one‐period monopoly profit, in equilibrium, consumers will pay a premium for the more heavily advertised brand.

Transmission mechanisms of conventional and unconventional monetary policies in open economies

This paper provides an empirical examination on the transmission mechanisms of conventional and unconventional monetary policies for two non-EMU countries, Switzerland and the United Kingdom, over the period 1990–2017. We investigate the role of stock prices and consumer expectations in the transmission of monetary policy. We propose two distinct structural VAR models. The model for the case of conventional monetary policy covers the pre-2009 period, while the model for the case of unconventional monetary policy covers the post-2009 period. The official bank policy rate and central bank’s reserve assets are used as instruments for conventional and unconventional monetary policy. The analysis reveals that the inclusion of a forward-looking informational variable of near-term development in economic activity and a financial variable such as the stock prices is of key importance for the monetary policy assessment. We provide evidence for the existence of a consumer confidence channel in the transmission of conventional monetary policy. Moreover, the long-term government bond yields, the exchange rate and stock prices have an important role in the transmission of unconventional monetary policy. Our findings indicate that conventional and unconventional monetary policies have short-run expansionary effects in both countries by increasing output, consumption, investment, stock prices and wages, while reducing unemployment.

     

Learning and relationship orientation: an empirical examination in European museums

• The purpose of this paper is to assess the interrelations between learning orientation, innovation strategy, relationship orientation and economic and social performance in the management of cultural organizations such as museums. We first provide a review of the literature addressing the main constructs involved in the research: learning orientation, innovation, relationship orientation and performance, and we detail the model's hypotheses reflecting the interrelations amongst the proposed variables. Building on extensive literature, a model is developed and empirically tested using survey data collected from 491 European museums in Spain, France, Italy and the UK. Data are analysed through structural equation modelling. In the present study, evidence is found to support the positive and significant link between learning orientation and internal (organizational innovation) as well as external (relationship orientation) changes in museums. Further, we find that organizational innovation and relationship orientation aid the introduction of greater technological developments in these organizations. We also find evidence to support the idea that learning orientation, innovation strategy and relationship orientation impact the economic and social performance of museums. Findings clearly show that achieving organizational objectives through learning processes necessarily entails the introduction of internal changes—innovation—and external relationships—relationship orientation.

Approximation of aggregate and extremal losses within the very heavy tails framework

The loss distribution approach is one of the three advanced measurement approaches to the Pillar I modeling proposed by Basel II in 2001. In this paper, one possible approximation of the aggregate and maximum loss distribution in the extremely low frequency/high severity case is given, i.e. the case of infinite mean of the loss sizes and loss inter-arrival times. In this study, independent but not identically distributed losses are considered. The minimum loss amount is considered increasing over time. A Monte Carlo simulation algorithm is presented and several quantiles are estimated. The same approximation is used for modeling the maximum and aggregate worldwide economy losses caused by very rare and very extreme events such as 9/11, the Russian rouble crisis, and the U.S. subprime mortgage crisis. The model parameters are fit on a data sample of operational losses. The respective aggregate and extremal loss quantiles are calculated.     

Competition in wholesale markets: Do MNOs compete to host MVNOs?

This paper extends previous research examining wholesale market shares of mobile network operators (MNOs). This study demonstrates that wholesale market concentration has decreased over time because of the increase of competition of MNOs for hosting mobile virtual network operators (MVNOs). However, differences in wholesale market shares between MNOs have not disappeared. We propose that those operators that are late entrants in a market and belong to an international group with a proactive attitude towards hosting virtual operators positively influences wholesale market shares of MNOs. The empirical analysis is based on a panel data from 2000 to 2010 corresponding to MNOs and virtual operators in five European countries with high development of the virtual mobile industry. By closely examining KPN we show how being an international mobile group specialising in the wholesale market across Europe has enabled it to exploit complementarities that exist between traditional and virtual businesses.     

True and fair in the Czech Republic: a note on local perceptions

With the collapse of communism in Czechoslovakia’, and the subsequent desire of Czechoslovakia to join the European Union, in common with other countries in Central Europe, Czechoslovakia utilized the Fourth Directive as a ‘toolkit’ in designing part of its new accounting legislation. In incorporating the Fourth Directive, it has also included the requirement for financial statements to show a ‘true and fair’ view. Given the confusion over the exact meaning of ‘true and fair’ it is interesting to study how ‘true and fair’ has been introduced into the Czech Republic, and what it seems to signify for those who implemented it and for those who are preparing and using financial statements. Our initial findings indicate that ‘true and fair’ varies in its significance for the groups of individuals involved in preparing and using financial statements and that it may have particular significance for some groups of accountants who wish to secure specific advantage within the Czech economy.With the collapse of communism in Czechoslovakia’, and the subsequent desire of Czechoslovakia to join the European Union, in common with other countries in Central Europe, Czechoslovakia utilized the Fourth Directive as a ‘toolkit’ in designing part of its new accounting legislation.

Discretion vs. timeless perspective under model-consistent stabilization objectives

Recent literature has reported situations in which discretion dominates timeless perspective in the presence of elements that reduce the slope of the New Keynesian Phillips curve. Considering a model-consistent welfare metric inhibits this mechanism in the standard New Keynesian framework.     

The impact of regulatory change on EU energy utility returns: the three liberalization packages

The European Union’s (EU) energy sector is changing due to major policy reforms. In this article, we examine the impact of major legislative changes which were designed to induce competition in the energy sector: the three liberalization packages. Competition was expected to benefit the industry by phasing out inefficient firms. EU citizens were also expected to benefit as competition was likely to promote a more efficient energy sector and more consumer choice of energy products and services. However, this legislative change occurred during a period of extreme market turmoil. We examine the impact of all these changes on the risk profile of the sector. Our results show that the liberalization legislation significantly increased systematic risk exposure of the sector, reducing its role as a defensive investment asset. We also show that commodities had relatively little impact on sector returns, but this was expected as utilities can offset commodity risk in hedging markets. We compare our results to those obtained in neighbouring EU sectors and find the impacts are isolated to the energy sector. This article makes a major contribution to energy policy by empirically showing the change in risk as a result of sector liberalization.
