Smart choices for growth. Bruegel Policy Contribution 2012/21, November 2012

Recovery in Greece, Italy, Portugal and Spain is held back in part by structural barriers. Overcoming these requires structural reform and public investment. Given the limited availability of political and financial capital, prioritising reform efforts and spending is important, but difficult. The different success factors for individual sectors are complementary. Using the example of the high-tech industry, we make the case that only investing in one success factor (eg broadband infrastructure) without having a sufficient endowment of others (eg education) is unlikely to make the sector successful. One consequence of the complementarity of the different success factors is that public investment and reform efforts should be fine-tuned in order to match the endowment of other factors. This might imply an increase in efforts to tackle several structural barriers at the same time, but it might also imply reducing investment in less promising fields. This in turn requires strategic thinking about whether it is worthwhile pursuing development strategies that require investment in many success factors but that do not promise much success. Such a strategic approach to public investment and reform efforts might make the allocation of scarce public financial and political capital more efficient.

A qualified defense of American drone attacks in northwest Pakistan under international humanitarian law

Since the terrorist attacks of September 11, 2001, international law has had to grapple with the fundamental challenges that large-scale violence carried out by non-State actors poses to the traditional inter- State orientation of international law. Questions related to the “adequacy” and “effectiveness” of international humanitarian law, international human rights law and the law related to the use of force have been particularly pronounced. This paper focuses on the international humanitarian law implications of American drone attacks in northwest Pakistan. A highly-advanced modality of modern warfare, armed drones highlight the possibilities, problems, prospects and pitfalls of high-tech warfare. How is the battlefield to be defined and delineated geographically and temporally? Who can be targeted, and by whom? Ultimately, this paper concludes that American drone attacks in northwest Pakistan are not unlawful as such under international humanitarian law, though, like any tactical decision in the context of asymmetric warfare, they should be continuously and closely monitored according to the dictates of law with sensitivity to facts on the ground.

Negative online consumer reviews: effects of different responses

Purpose When consumers buy online, they are often confronted with consumer reviews. A negative consumer review on an online shopping website may keep consumers from buying the product. Therefore, negative online consumer reviews are a serious problem for brands. This paper aims to investigate the effects of different response options to a negative consumer review. Design/methodology/approach In an online experiment of 446 participants different response options towards a negative consumer review on an online shopping website are examined. The experimental data is analysed with simple linear regression models using product purchase intentions as the outcome variable. Findings The results indicate that a positive customer review counteracts a negative consumer review more effectively than a positive brand response, whereas brand strength moderates this relationship. Including a reference to an independent, trusted source in a brand or a customer response is only a limited strategy for increasing the effectiveness of a response. Research limitations/implications Additional research in other product categories and with other subjects than students is suggested to validate the findings. In future research, multiple degrees of the phrasing’s strength of the reference could be used. Practical implications Assuming high quality products, brands should encourage their customers to write reviews. Strong brands can also reassure consumers by responding whereas weak brands cannot. Originality/value This research contributes to the online consumer reviews literature with new insights about the role of brand strength and referencing to an independent, trusted source.

Module property verification : A method to plan and perform quality verifications in modular architectures

Modular product architectures have generated numerous benefits for companies in terms of cost, lead-time and quality. The defined interfaces and the module’s properties decrease the effort to develop new product variants, and provide an opportunity to perform parallel tasks in design, manufacturing and assembly. The background of this thesis is that companies perform verifications (tests, inspections and controls) of products late, when most of the parts have been assembled. This extends the lead-time to delivery and ruins benefits from a modular product architecture; specifically when the verifications are extensive and the frequency of detected defects is high. Due to the number of product variants obtained from the modular product architecture, verifications must handle a wide range of equipment, instructions and goal values to ensure that high quality products can be delivered. As a result, the total benefits from a modular product architecture are difficult to achieve. This thesis describes a method for planning and performing verifications within a modular product architecture. The method supports companies by utilizing the defined modules for verifications already at module level, so called MPV (Module Property Verification). With MPV, defects are detected at an earlier point, compared to verification of a complete product, and the number of verifications is decreased. The MPV method is built up of three phases. In Phase A, candidate modules are evaluated on the basis of costs and lead-time of the verifications and the repair of defects. An MPV-index is obtained which quantifies the module and indicates if the module should be verified at product level or by MPV. In Phase B, the interface interaction between the modules is evaluated, as well as the distribution of properties among the modules. The purpose is to evaluate the extent to which supplementary verifications at product level is needed. Phase C supports a selection of the final verification strategy. The cost and lead-time for the supplementary verifications are considered together with the results from Phase A and B. The MPV method is based on a set of qualitative and quantitative measures and tools which provide an overview and support the achievement of cost and time efficient company specific verifications. A practical application in industry shows how the MPV method can be used, and the subsequent benefits

Building an Interactive, Three-dimensional Virtual World

The movement of graphics and audio programming towards three dimensions is to better simulate the way we experience our world. In this project I looked to use methods for coming closer to such simulation via realistic graphics and sound combined with a natural interface. I did most of my work on a Dell OptiPlex with an 800 MHz Pentium III processor and an NVIDlA GeForce 256 AGP Plus graphics accelerator -high end products in the consumer market as of April 2000. For graphics, I used OpenGL [1], an open·source, multi-platform set of graphics libraries that is relatively easy to use, coded in C . The basic engine I first put together was a system to place objects in a scene and to navigate around the scene in real time. Once I accomplished this, I was able to investigate specific techniques for making parts of a scene more appealing.

Estratégia de canais de marketing na indústria de software : estudo de caso sobre a Microsoft no Brasil

Mercados com dinâmica competitiva baseada na inovaçâo são incertos e sujeitos a rupturas dos negócios envolvidos. Isto é bastante diferente dos mercados maduros, nos quais o equilíbrio de forças estabelece uma estrutura industrial relativamente estável. Mercados de inovação, ou high-tech, e em especial os de tecnologia da informação também estão sujeitos a outros fenômenos ou características que os distinguem dos mercados maduros. Trabalhamos com alguns destes fenômenos como: a difusão tecnológica, a qual está ligada a fatores psicológicos que motivam ou inibem a adoção da tecnologia por parte do cliente; o aprisionamento; a externalidades de rede; a disputas por padrões e a concorrência entre cadeias de valor distintas. Estas características demandam serviços, orientação do cliente quanto ao uso da tecnologia e casos de sucesso exemplares para vencer os fatores inibidores e estimular os fatores motivadores do cliente no seu processo de adoção da tecnologia. A teoria explica que os canais de marketing podem oferecer vantagem competitiva às empresas que bem se utilizam deles, e as características de demanda por serviços e orientação de uso pelos clientes podem ser bem atendidas pelos canais de marketing. Esta pesquisa testa esta teoria através de um estudo de caso sobre a Microsoft, empresa do ramo de software que tem sua atividade fortemente baseada em canais de marketing. Verificamos a teoria, isto é, o canal sendo um elemento diferencial e gerador de vantagem competitiva para a empresa

As competências essenciais dos profissionais em vendas de bens perecíveis: um modelo genérico de competências

Esta tese estuda as competências essenciais requeridas dos profissionais em vendas de bens perecíveis diante das mudanças ambientais e novas estratégias de relacionamento entre as indústrias de alimentação e seus canais de marketing. Há revisões teóricas sobre marketing e venda pessoal no lado da Administração e sobre competências no lado da Psicologia. Da revisão teórica foram selecionadas 16 competências chave para compor um dicionário, convenientes ao atual contexto de relacionamento entre comprador e vendedor. A pesquisa foi conduzida entre participantes de comitês do Movimento ECR Brasil, funcionários de supermercados e de indústrias de alimentação (n = 192). Empregaram-se as técnicas estatísticas da análise fatorial exploratória e da análise fatorial confirmatória e o modelo teórico foi gerado com três dimensões - suporte à competitividade, relacionamento eficaz e integração operacional - abrangendo 12 competências essenciais. Foram testadas as validades convergente, discriminante e nomológica dos constructos do modelo teórico. Quanto às medidas de ajustamento global do modelo teórico mais o índice esperado de validação cruzada (ECVI) foi possível constatar que o modelo demonstrou consistência com os dados e teve uma boa aproximação da população (X² = 68,15, DF = 51, p = 0,054, RMSEA = 0,042). A avaliação dos resultados do modelo de medidas revelou evidência parcial quanto à validade dos constructos e baixa fidedignidade quanto aos indicadores do modelo teórico.
