Learning in peer-to-peer markets: evidence from Airbnb

Peer-to-peer markets are highly uncertain environments due to the constant presence of shocks. As a consequence, sellers have to constantly adjust to these shocks. Dynamic Pricing is hard, especially for non-professional sellers. We study it in an accommodation rental marketplace, Airbnb. With scraped data from its website, we: 1) describe pricing patterns consistent with learning; 2) estimate a demand model and use it to simulate a dynamic pricing model. We simulate it under three scenarios: a) with learning; b) without learning; c) with full information. We have found that information is an important feature concerning rental markets. Furthermore, we have found that learning is important for hosts to improve their profits.

A influência da adição de caulim, quartzo e feldspato potássico na formulação de massas cerâmicas para telhas: Modelo estatístico

The production of roof tiles in the state of Rio Grande do Norte accounts for around 60% of the total of ceramic pieces produced. There is a need for investment to improve quality and productivity, thereby promoting technological innovations. Accordingly, the aim of this study is to determine the effect of kaolin, potassium feldspar and quartz in two standard formulations, as well as the effect of sintering temperature on the technological properties of linear firing shrinkage, water absorption and bending rupture stress, by fitting the statistical model and using multiple linear regression to assess the relationship between technological properties and independent variables. The raw materials were characterized using the following techniques: X-ray fluorescence (XRF), X-ray diffraction (XRF), rational analysis (RA), differential thermal analysis (DTA) and granulometric analysis (GA). The test specimens were compacted by uniaxial pressure (25 MPa), dried in a stove at 110 ºC for 24 hours and sinterized at 850 ºC, 950 ºC and 1050 ºC and held isothermal for 30 minutes. The results obtained indicate that the addition of kaolin to two standard formulations (M and R) promoted a reduction in water absorption values and an increase in bending rupture stress values. The sintering temperatures for group M that resulted in the lowest linear firing shrinkage and water absorption values were 850 ºC and 950 ºC, respectively, and the highest bending rupture stress values were reached at a temperature of 950 ºC. In the case of group R, the sintering temperature that obtained the lowest water absorption and linear firing shrinkage values was 850 ºC, and the highest bending rupture stress values were attained at a temperature of 1050 ºC. This work explains the statistical approach used to fit the model that describes the relationship between the technological properties and percentage of kaolin, quartz and feldspar, as well as the models that enable predictions, provided that the lower and upper limits of the percentage of clay minerals, flux and quartz used in this study are respected. Statistica 6 software was used and results were obtained by stepwise forward regression

Flexibilização produtiva e desenvolvimento local: a rede de subcontratação da Alunorte

Consiste no estudo sobre a formação de uma rede de empresas prestadoras de serviço subcontratadas pela Alunorte, como conseqüência do processo de flexibilização produtiva desta indústria de alumina, localizada no distrito industrial de Barcarena, no Estado do Pará. O objetivo principal é analisar se a relação estabelecida entre essa grande indústria e sua rede de subcontratadas e deste conjunto de empresas com as instituições locais tem desencadeado efeitos germinativos locais de desenvolvimento. Tem como base teórica diversos estudos, segundo os quais, é a partir do modo como esses agentes interagem, articulando-se através de sistemas de inovação, que se define o formato do arranjo produtivo ou cadeia de firmas. Tal formato será ou não capaz de estimular a produção contínua e disseminada de inovações tecnológicas e organizacionais, bem como a formação de capital humano e social, fundamentais para impulsionar o desenvolvimento endógeno. A pesquisa de campo, porém, demonstrou que, apesar do relacionamento com a maior produtora mundial de alumina, indústria vinculada à lógica global de competitividade e de inovação tecnológica e gerencial, não há uma ampla difusão e assimilação desse conhecimento entre as empresas subcontratadas. Não apenas em função da insuficiência de qualificação e de condições tecnológicas para isso, mas também pela ausência de relações de confiança mútua e de cooperação produtiva e inovativa entre as referidas empresas e destas com a rede de instituições locais. Essa lacuna inviabiliza possíveis avanços desse arranjo produtivo, em tennos de obtenção de economias de escala e de melhorias nos níveis de produtividade e competitividade. Não há, portanto, um ambiente favorável às iniciativas dinamizadoras do desenvolvimento local.

Relações inter-firmas em Barcarena/PA: um estudo das práticas de inovação e cooperação na rede de fornecedores e subcontratados da IRCC

Este trabalho tem como objetivo apresentar um estudo das relações inter-firmas estabelecidas entre empresas mínero-metalúrgicas localizadas no distrito industrial do município de Barcarena, no estado do Pará, a partir da análise das interações entre uma empresa central e sua rede de fornecedores e subcontratados, que operacionalizam o beneficiamento e a exportação do mineral conhecido como caulim. Segundo as abordagens teóricas que defendem a ocorrência e a disseminação de inovações tecnológicas como base para o desenvolvimento econômico, realizou-se um estudo sobre a forma como os arranjos produtivos são capazes de gerar e manter vantagens competitivas a partir de sistemas de inovação baseados em redes cooperativas integradas por um grupo específico de agentes públicos e privados. Os resultados da pesquisa mostram que, em que pese a existência de inovações nos processos produtivos, em função das exigências técnicas apresentadas por seus contratantes, as empresas subcontratadas, via de regra, não conseguem estabelecer relações de cooperação capazes de promover a disseminação destas inovações, assim como também geralmente não dispõem de recursos gerenciais e tecnológicos capazes de gerar inovações de produtos ou de transformar as inovações de processos em significativos ganhos de produtividade. A ausência de cooperação entre as empresas estende-se aos relacionamentos com os outros agentes, tais como instituições de ensino e pesquisa, de treinamento e capacitação técnica, órgãos de fomento e crédito, associações, cooperativas e sindicatos. Conseqüentemente, a rede de subcontratação desperdiça o potencial de ganhos sinérgicos capazes de elevar os patamares de competitividade local. Abordam-se também as implicações do estudo para a pesquisa, para o desenvolvimento local e para o planejamento e as políticas públicas.

Gestão do conhecimento e recursos humanos em bibliotecas universitárias brasileiras e portuguesas

The Knowledge Management represents a new vision of management of organizations, since information and knowledge are the main factors of competitiveness, today, of individuals, organizations and nations. The university plays a key role alongside with government and industry in the generation of technological innovations that can help the society progress, and the University Library is an important disseminator of scientific information. The main challenges of organizations involved in Knowledge Management are concentrated in the management of cultural and behavioral changes of its human resources and in creating an environment conducive to create, use and share information and knowledge. Within this context the question arises: How do University Libraries in Brazil and Portugal employ people management and knowledge management in order to improve the quality of its services and the productivity of their institutions? To answer it we developed a descriptive-analytic research, using the method of comparative study, analyzing 69 organizations. According to the survey results, the people management issues were the worst assessed in relation to other aspects of Knowledge Management, showing a weak dissemination of these practices in the University Libraries of Brazil and Portugal and the great need for initiatives to help develop them.

Aplicação do valor presente ajustado (APV) para avaliação do fluxo de caixa de uma empresa do setor automotivo no sistema inovar auto

The automobile industry shows relevance inside the Brazilian industrial scenario since it contributes with the development of a significant chain of supply, distributors, workshops, publicity agencies and insurance companies in the internal market, aside from being one of the five biggest worldwide market. Thereby, the federal government decreed in Dec, 17th 2012 by Law nº 12.715 the Inovar-Auto Program. As the Adjusted Present Value (APV) is highly recommended, although not yet widespread to public politics of tax reduction, this work intends to apply the APV method on the cash flow analysis of an automobile sector's company, which has recently installed in national territory and wants to rely with governmental incentives proposed by Inovar-Auto Program. The developed work evaluates the company's current cash flow stochastically from mathematical modeling of variables such as price, demand and interest rate through probability distributions with the assist of Crystal Ball software, a Microsoft Excel Add-in, generating different scenarios from Monte Carlo Simulation. As results probabilities situations have been evaluated until the end of the Inovar-Auto's conducted period, in 2017. Beside APV others indicator such as Internal Rate of Return (IRR) and payback period were estimated for the investment project. For APV a sampling distribution with only 0.057% of risk, IRR of 29% were obtained and estimated project payback period was 4.13 years
