Optimal financiai strategies are criticai for long term survival in competitive international markets. Financial strategies pertaining to transfer pricing have become increasingly important as income tax authorities seek additional revenues through increased monitoring of company practices. In this first of two articles, optimal tax strategies are presented after reviewing the transfer pricing concept and the rationale underlying governments' increased focus on transfer pricing. In the second forthcoming article, we analyze the effect of government restrictions on optimal pricing strategies.

Transfer pricing is a pervasive issue that presents significant tax savings potential concerning international enterprises. The authors discuss company incentives to manage transfer prices in an article appearing in the preceding issue of this journal. In response to these incentives, governments have increasingly enacted and enforced domestic restrictions on transfer prices. In this article, contemporary norms restricting transfer pricing are analyzed. The OEGO and US pricing standards are assessed and Brazil's recent application of these standards is considered. Transfer pricing methods are described and evidence of their use is presented. We conclude by describing an intercompany transfer pricing policy intended to facilitate internaI financiaI management and minimize externaI tax threats.

This article jointly examines the differences of laboratory versions of the Dutch clock open auction, a sealed-bid auction to represent book building, and a two-stage sealed bid auction to proxy for the “competitive IPO”, a recent innovation used in a few European equity initial public offerings. We investigate pricing, seller allocation, and buyer welfare allocation efficiency and conclude that the book building emulation seems to be as price efficient as the Dutch auction, even after investor learning, whereas the competitive IPO is not price efficient, regardless of learning. The competitive IPO is the most seller allocative efficient method because it maximizes offer proceeds. The Dutch auction emerges as the most buyer welfare allocative efficient method. Underwriters are probably seeking pricing efficiency rather than seller or buyer welfare allocative efficiency and their discretionary pricing and allocation must be important since book building is prominent worldwide.

O artigo examina aspectos correspondentes ao relacionamento entre o nível de vendas e o capital de giro necessário para manter a continuidade operacional dos negócios, em um contexto em que a alavancagem de vendas ocorre como resultado de um programa de ações de pricing. Discute-se qual deve ser o ponto de equilíbrio baseado no capital de giro, de modo a auxiliar os administradores a analisar os efeitos daquele tipo de alavancagem nos procedimentos financeiros de uma empresa.

A geração de poupança interna e a ampliação do investimento produtivo é condição para alcançar e manter taxas de crescimento econômico compatíveis com o desenvolvimento social. Os fundos de pensão, com os recursos disponíveis para investir, possibilitam alavancar o desenvolvimento de um país na medida em que canalizam esses recursos para o setor produtivo. Diante dessa perspectiva, este estudo propõe analisar o desempenho das aplicações em renda variável desses fundos, aqui considerados investimento produtivo, por meio do Capital Asset Pricing Model (CAPM) e dos índices de Sharpe e M² . Estes se prestam a avaliar o investimento realizado em relação ao risco e ao retorno da carteira. A partir da metodologia proposta, verificou-se que os investimentos em ações incorreram em retornos superiores aos esperados, garantindo eficiência na remuneração pelo risco, gerando, por um lado, maior valor agregado ao fundo e, por outro, um incremento da poupança interna do país, respaldado pela aplicação de recursos no setor produtivo.

Nas últimas décadas, o modelo Capital Asset Pricing Model (CAPM) tem despertado grande interesse por parte da comunidade científica. Apesar das críticas, o aprimoramento do CAPM estático deu origem a novos modelos dinâmicos que trazem maior segurança para o investidor ao longo do ciclo de negócios. Atualmente, encontramos adaptações mais complexas do modelo CAPM, as quais nos permitem ter respostas sobre questões em finanças que por muito tempo permaneceram não solucionadas. Diante desse panorama e considerando todo o debate acerca da validade do CAPM, este trabalho tem como objetivo testar o modelo CAPM condicional de Jagannathan e Wang (1996), incorporando variáveis macroeconômicas e financeiras, para o mercado brasileiro, argentino, chileno, e norte americano.

The aim of this paper is to analyze the determining factors for the pricing of handsets sold with service plans, using the hedonic price method. This was undertaken by building a database comprising 48 handset models, under nine different service plans, over a period of 53 weeks in 2008, and resulted in 27 different attributes and a total number of nearly 300,000 data registers. The results suggest that the value of monthly subscriptions and calling minutes are important to explain the prices of handsets. Furthermore, both the physical volume and number of megapixels of a camera had an effect on the prices. The bigger the handset, the cheaper it becomes, and the more megapixels a camera phone has, the more expensive it becomes. Additionally, it was found that in 2008 Brazilian phone companies were subsidizing enabled data connection handsets.

Este artigo analisa a questão do conservadorismo no que concerne à gestão de recursos por tesourarias de instituições financeiras públicas, que incorrem em um trade-off por não ter essa gestão como prioridade, mas sim as atividades associadas ao desenvolvimento. Fazendo-se uso do capital asset pricing model (CAPM), as evidências para o Banco do Nordeste do Brasil, o maior banco de desenvolvimento regional da América Latina, sugerem que sejam viáveis as mudanças institucional e na legislação que restringe a política de investimentos dessas organizações.

ABSTRACTOBJECTIVE To assess inter-rater reliability, test-retest reliability, and construct validity of retail food store, open-air food market, and restaurant observation tools adapted to the Brazilian urban context.METHODS This study is part of a cross-sectional observation survey conducted in 13 districts across the city of Sao Paulo, Brazil in 2010-2011. Food store and restaurant observational tools were developed based on previously available tools, and then tested it. They included measures on the availability, variety, quality, pricing, and promotion of fruits and vegetables and ultra-processed foods. We used Kappa statistics and intra-class correlation coefficients to assess inter-rater and test-retest reliabilities in samples of 142 restaurants, 97 retail food stores (including open-air food markets), and of 62 restaurants and 45 retail food stores (including open-air food markets), respectively. Construct validity as the tool’s abilities to discriminate based on store types and different income contexts were assessed in the entire sample: 305 retail food stores, 8 fruits and vegetable markets, and 472 restaurants.RESULTS Inter-rater and test-retest reliability were generally high, with most Kappa values greater than 0.70 (range 0.49-1.00). Both tools discriminated between store types and neighborhoods with different median income. Fruits and vegetables were more likely to be found in middle to higher-income neighborhoods, while soda, fruit-flavored drink mixes, cookies, and chips were cheaper and more likely to be found in lower-income neighborhoods.CONCLUSIONS The measures were reliable and able to reveal significant differences across store types and different contexts. Although some items may require revision, results suggest that the tools may be used to reliably measure the food stores and restaurant food environment in urban settings of middle-income countries. Such studies can help .inform health promotion interventions and policies in these contexts.

The evolutionary history and times of divergence of triatomine bug lineages are estimated from molecular clocks inferred from nucleotide sequences of the small subunit SSU (18S) and the second internal transcribed spacer (ITS-2) of the nuclear ribosomal DNA of these reduviids. The 18S rDNA molecular clock rate in Triatominae, and Prosorrhynchan Hemiptera in general, appears to be of 1.8% per 100 million years (my). The ITS-2 molecular clock rate in Triatominae is estimated to be around 0.4-1% per 1 my, indicating that ITS-2 evolves 23-55 times faster than 18S rDNA. Inferred chronological data about the evolution of Triatominae fit well with current hypotheses on their evolutionary histories, but suggest reconsideration of the current taxonomy of North American species complexes.

In Mexico, Triatoma longipennis (Usinger), Triatoma picturata (Usinger), and Triatoma pallidipennis (Stal), primary Chagas disease vector species of the phyllosoma complex, were analyzed by randomly amplified polymorphic DNA (RAPD). Sixteen decametric primers resolved individual profiles not identical, but partially discriminative between species. Analysis based on pairwise presence/absence comparisons between the three species was performed using three primers and two outgroup species Triatoma infestans (Klug) and Triatoma barberi (Usinger). Fifty-three bands in total were scored, although only two bands were constant among the three phyllosoma complex species. Two other bands were constant only for T. longipennis and T. picturata together, and not present in T. pallidipennis. Neighbor Joining tree and the multiple correspondence analysis discriminated T. pallidipennis clearly from the other two species, although there was overlap between T. longipennis and T. picturata. The results indicate a close relationship between the studied species and support the hypothesis of their recent evolution. The suitability of RAPD to discern populations within the species is discussed.
