Effects of transportation accessibility on residential property values: Application of spatial hedonic price model in Seoul, South Korea, metropolitan area

A number of studies have focused on estimating the effects of accessibility on housing values by using the hedonic price model. In the majority of studies, estimation results have revealed that housing values increase as accessibility improves, although the magnitude of estimates has varied across studies. Adequately estimating the relationship between transportation accessibility and housing values is challenging for at least two reasons. First, the monocentric city assumption applied in location theory is no longer valid for many large or growing cities. Second, rather than being randomly distributed in space, housing values are clustered in space—often exhibiting spatial dependence. Recognizing these challenges, a study was undertaken to develop a spatial lag hedonic price model in the Seoul, South Korea, metropolitan region, which includes a measure of local accessibility as well as systemwide accessibility, in addition to other model covariates. Although the accessibility measures can be improved, the modeling results suggest that the spatial interactions of apartment sales prices occur across and within traffic analysis zones, and the sales prices for apartment communities are devalued as accessibility deteriorates. Consistent with findings in other cities, this study revealed that the distance to the central business district is still a significant determinant of sales price.

New evidence on the green building rent and price premium

This paper investigates the effect of voluntary eco-certification on the rental and sale prices of US commercial office properties. Hedonic and logistic regressions are used to test whether there are rental and sale price premiums for LEED and Energy Star certified buildings. The results of the hedonic analysis suggest that there is a rental premium of approximately 6% for LEED and Energy Star certification. A sale price premium of approximately 35% was found for 127 price observations involving LEED rated buildings and 31% for 662 buildings involving Energy Star rated buildings. When compared to samples of similar buildings identified by a binomial logistic regression for LEED-certified buildings, the existence of a rent and sales price premium is confirmed albeit with differences regarding the magnitude of the premium. Overall, the results of this study confirm that LEED and Energy Star buildings exhibit higher rental rates and sales prices per square foot controlling for a large number of location- and property-specific factors.

Besides tracking: Simulation of RFID marketing and beyond

This paper asks a new question: how we can use RFID technology in marketing products in supermarkets and how we can measure its performance or ROI (Return-on-Investment). We try to answer the question by proposing a simulation model whereby customers become aware of other customers' real-time shopping behavior and may hence be influenced by their purchases and the levels of purchases. The proposed model is orthogonal to sales model and can have the similar effects: increase in the overall shopping volume. Managers often struggle with the prediction of ROI on purchasing such a technology, this simulation sets to provide them the answers of questions like the percentage of increase in sales given real-time purchase information to other customers. The simulation is also flexible to incorporate any given model of customers' behavior tailored to particular supermarket, settings, events or promotions. The results, although preliminary, are promising to use RFID technology for marketing products in supermarkets and provide several dimensions to look for influencing customers via feedback, real-time marketing, target advertisement and on-demand promotions. Several other parameters have been discussed including the herd behavior, fake customers, privacy, and optimality of sales-price margin and the ROI of investing in RFID technology for marketing purposes. © 2010 Springer Science+Business Media B.V.

Marketing of value-added products from silver carp and involvement of rural people in the production and marketing chain

Cost-profit analysis and market testing of some value-added products from silver carp such as fish mince block, fish sausage, fish ball, fish stick and fish burger were analyzed during April 2001 to March 2002. The study also explored the possibility to involve rural low-income people in the production and marketing of such products. The production of silver carp was higher in greater Jessore and Mymensingh districts but the price remained low during the peak-harvesting season in October to November. The price varied with size of the fish, season, market characteristics and effective demand of the buyers. Price of about 500 g size fish was found to be Tk. 20-25/kg in the rural markets. The average size of fish in the rural markets was 3S0-550 g while that in the urban markets it was 700-1,200 g. The cost of production of the value added products and profit margin were assessed on the basis of market price of the raw material as well as that of the finished products, transportation, storage and marketing costs. The profit margins of 34%, 39%, 81% and 31% of their sales price were obtained for fish sausage, fish ball, fish stick and fish burger, respectively. Actual production cost could be minimized if the fish is purchased directly from the farmers. Consumer's acceptance and marketability tests showed that both rural and urban people preferred fish ball than fish sausage. However, response towards the taste, flavor and color of fish ball and fish sausage was found to vary with occupations and age of the consumers. A correlation was observed between age group and acceptance of new products. Fish ball, fish stick and fish burger were found to be the most preferable items to the farmers because of easy formulation process with common utensils. Good marketing linkage and requirement of capital had been identified as the prerequisites for operating small-scale business on value-added fish products.

“Private label products: A category analysis”

The presented dissertation was developed within a partnership between Nova School of Business and Economics and the Portuguese retailer Sonae MC. The main objective of the study was to develop an analysis for the confectionary category to identify potential development opportunities for new Private Label products. In order to do so, the starting point was to understand how the confectionery market was behaving, followed by and understanding of Continente’s performance in that market. Aiming to point out development opportunities, the analysis was split between the subcategories – Chocolate, Chewing Gums and Sweets. The Subcategory performance was assessed in terms of sales, number of SKU’s, Private Label weight and it market position in terms of share. For the potential development opportunities a comparison between the top selling Branded Product and the competitors’ position was developed, in order to establish a reasonable size and retail price for such products.

A theory of weekly specials

Multiproduct retailers facing similar costs and serving the same public commonly announce different weekly specials. These promotional prices also seem to evolve randomly over the weeks. Here, weekly specials are viewed as the strategic outcome of an oligopolistic price competition among multiproduct retail stores facing nonconvex costs. Existence of an equilibrium in mixed strategies is proven. ldentical stores serving the same public will never charge the same price vector with probability one (cross-store price dispersion). Mixed strategies can generate random price dispersion over time in the repeated version of the mode!.

Custos e rentabilidade da produção de juvenis de tilápia-do-nilo em tanques-rede utilizando-se diferentes densidades de estocagem

Neste trabalho foi realizada a análise econômica da produção de juvenis de tilápia-do-nilo em tanques-rede utilizando-se diferentes densidades de estocagem. O experimento foi desenvolvido em área aquícola, em delineamento de blocos casualizados, com quatro densidades de estocagem (100, 200, 300 e 400 peixes m-3), avaliadas com seis repetições, em dois períodos de criação: de março a abril de 2005 (52 dias - peso inicial de 43,08 ± 2,98 g e peso final de 262,14 ± 47,86 g) e de março a abril de 2006 (58 dias - peso inicial de 43,16 ± 5,34 g e peso final 314,24 ± 73,30 g). Foram avaliadas as seguintes variáveis econômicas: custo da ração mais custo do juvenil dividido pela biomassa, em R$ kg-1; porcentagem do custo da ração por quilo de peixe produzido sobre o preço de venda; porcentagem do custo do juvenil por quilo de peixe produzido sobre o preço de venda e; porcentagem dos custos da ração mais do juvenil por quilo de peixe produzido sobre o preço de venda. da menor densidade de estocagem (100) para a maior (400), ocorreu diminuição no ganho de peso diário e elevação do índice de conversão alimentar aparente, mas essa redução não comprometeu a taxa de sobrevivência. Entretanto, o ganho de biomassa aumentou com o adensamento de peixes. As maiores receitas líquidas foram obtidas nas densidades de estocagem de 100 e 200 peixes m-3. Os preços não remuneraram os custos operacionais (efetivo e total) em maiores densidades (300 e 400 peixes m-3). Os melhores resultados para a produção de juvenis de tilápia-do-nilo foram obtidos com densidades de até 200 peixes m-3.

Incorporação de novas tecnologias no setor sucroalcooleiro: produção de hidrogênio e aumento da oferta de eletricidade

This work studies the incorporation of new technologies in the sugarcane sector. Are considered the ethanol steam reforming and the gasification of sugarcane bagasse(by-product) processes associated with combined cycle systems (Gas Turbine + Steam Turbine), aggregating hydrogen production and increased electricity supply in the sector, respectively. To verify the technical feasibility of the incorporation processes was performed a thermodynamic analysis, considering data from a typical Brazilian Sugar Cane Industry. In another step the economic viability study of the hydrogen production process was made, with consideration on hydrated and anhydrous ethanol steam reform, comparing the cost of hydrogen production. Also considered studies of economic engineering of the gasification process and the generation of electricity associated. As conclusions, it follows that the ethanol steam reforming is a great alternative for hydrogen production, presenting production cost relatively low, especially when is considered the steam reforming of hydrated ethanol. For the gasification process associated with combined cycle, can be observed an increase of 8.56 times of the electricity production in the sugar cane industry, indicating a positive annual saving when the sales price of the supply electricity is greater than 0.070 US$/kWh. Finally it can be concluded that the incorporation of these new processes allow greater profitability and operational flexibility of Brazilian sugarcane mills

Desempenho econômico de um sistema de produção de biomassa da cana energia

O uso da biomassa como fonte de energia elétrica corresponde a uma alternativa de grande importância para o planejamento estratégico do crescimento econômico de diversos países. A vasta extensão territorial e o clima favorável ao desenvolvimento da agricultura no Brasil trazem como vantagem o poder de planejar sua matriz energética utilizando variadas fontes primárias renováveis. A cana-de-açúcar destaca-se pela rusticidade e grande produtividade. O bagaço como um subproduto resultante do processamento da cana é utilizado como fonte para a cogeração de energia e pode contribuir significativamente para a descentralização das fontes de energia nacional. Com o desenvolvimento da tecnologia de etanol de segunda geração, a busca pela maior produção de biomassa ganha relevância. Os programas de melhoramento identificaram que se caso com redução de 25 a 35% da sacarose na cana, a planta teria um potencial de aumento de mais de 100% da biomassa. Os híbridos derivados de programas de melhoramento da espécie Saccharum spp., direcionados exclusivamente para a produção de biomassa, foram denominados de cana energia. Tendo em vista o potencial de produtividade da cultura e consequentemente de geração de energia, torna-se necessário conhecer se esse potencial se traduz em resultado econômico. Com esse enfoque, o objetivo deste trabalho foi analisar a viabilidade econômica da produção de biomassa da cana energia. Para tanto foi desenvolvido um modelo em planilha eletrônica e o modelo foi empregado na simulação de cenários e alternativas. A planilha integra modelos de balanço hídrico, produtividade da cultura e distribuição de chuvas, e suas relações com aspectos econômicos e produtivos. O preço de venda da biomassa, a produtividade da cultura e a distância de transporte se mostraram como os itens que mais influem sobre os indicadores de viabilidade econômica. Diferentemente da eficiência gerencial, a eficiência de campo corresponde a um fator de grande importância a ser considerado para reduzir o custo de produção. A análise da área de colheita como uma variável crítica indicou que existem módulos ideais para a utilização de máquinas agrícolas, reduzindo o seu custo operacional devido ao uso melhor atribuído das máquinas na propriedade. A análise da textura do solo como variável crítica mostrou que o cultivo da planta em diferentes tipos de solos reflete em diferentes custos operacionais, produtividade potencial e no montante de investimento. O ano de reforma corresponde a um fator crítico para a viabilização da atividade. Para o cenário base, o indicador de atratividade financeira apresenta um Valor Presente Líquido de 6,4 milhões de reais e uma Taxa Interna de Retorno de 15,2%, com um horizonte de 20 anos de produção. As análises de sensibilidade mostram que as variáveis que mais impactam nos indicadores de viabilidade econômica financeira são o preço de venda da biomassa e a produtividade média da lavoura.

Endogenous choice of decision variables

In this paper we allow the firms to choose their prices and quantities simultaneously. Quantities are produced in advance and their common sales price is determined by the market. Firms offer their “residual capacities” at their announced prices and the corresponding demand will be served to order. If all firms have small capacities, we obtain the Bertrand solution; while if at least one firm has a sufficiently large capacity, the Cournot outcome and a model of price leadership could emerge.

AN ECONOMIC ANALYSIS OF THE ADDITION OF BEVACIZUMAB TO STANDARD CHEMOTHERAPY IN PATIENTS WITH MALIGNANT PLEURAL MESOTHELIOMA

An examination of the techniques used to capture mangrove crabs, Ucides cordatus, in the Mamanguape River estuary, Northeastern Brazil, with implications for management.

The present research, undertaken in a mangrove swamp in northeastern Brazil (Mamanguape River Estuary), examined the factors that led to the overwhelming acceptance of the tangle-netting technique by crab harvesters in detriment to the now illegal tamping technique. Both techniques are the only ones currently used at our study site and in many other areas in Brazil, despite being prohibited by law. Data were collected through direct observations to determine capture efficiency, productivity, daily production, selectivity, and harvesting effort, and through interviews with crab harvesters, focusing on their perceptions of the capture techniques, the conditions of crab stocks and the sales price of a dozen crabs. Our results indicated that the two capture techniques did not significantly differ in terms of their efficiency or productivity, but daily production rates differed significantly, being greater using tangle-netting. The tangle-netting permits a greater harvesting effort (6 hours and 34 min) compared to tamping (4 hours and 19 min). Tangle-netting is also less selective than tamping indicated by the larger number of captured smaller specimens, including females. This results in a lower average sales price for a dozen crabs caught by tangle-netting (US$ 0.95) compared to tamping (US$ 1.02). The greater daily production of crab harvesters using the tangle-netting technique nevertheless increased their net gain, explaining their preference for this method, Given that tangle-netting results in greater harvesting pressure but lower selectivity compared to tamping, it may potentially be less sustainable. All of the crab harvesters interviewed having more than 20 years of experience (n = 34) stated they perceived that stocks of U. cordatus had become reduced over the last 20 years, together with average crab sizes. It is now important to examine the structure of the local U. cordatus population and to assess its fishery to allow evaluating whether the illegal, but prominent tangle-netting and tamping mangrove crab capture techniques are sustainable or not. We further suggest improving the dialogue between decision makers and fishermen, which barely exists to date, to initiate a discussion about possible ways of resolving the current situation of illegality of the fishermen. This will be key to achieving effective sustainable co-management of this important natural mangrove forest resource.
