A model for estimating fish population and optimal fishing effort in lakes and rivers

We developed a model for estimating the fish population for various species in lakes and rivers. Our estimation focuses, in its first step, on fish species that breed outside the lake. Using the annual outside supply of fingerlings, natural survival rate and reported amounts of fish caught, we estimated fish stock. Given the estimated stock for fish bred outside the lake, we can evaluate the catch rate. Assuming equal catch rates for other species, and given the amount caught for each species, we are able to evaluate each species stock. Using the proposed technique, we evaluated various species stocks in the Sea of Galilee (Lake Kinneret) in Israel. Using our suggested technique for evaluating fish stock, we calculated the optimal effort of fishing needed for maximizing steady state profit of the fishers.     

Competitive balance versus competitive intensity before a match: is one of these two concepts more relevant in explaining attendance? The case of the French football Ligue 1 over the period 2008–2011

The aim of this article is to investigate the determinants of attendance at French football Ligue 1 matches over the period 2008–2011 with an emphasis on examining the effects of both competitive balance and intensity before a match. Competitive balance is measured by the point difference between the two teams concerned by a match in the championship. Competitive intensity is measured by the point difference for the home team in relation to ranks with sporting stakes. Results show that competitive balance has an insignificant impact whereas competitive intensity has a significantly positive impact. Implications are drawn.     

Stock return reversal and continuance anomaly: new evidence from Hong Kong

Using weekly data, this article conducts a comprehensive analysis and presents new empirical evidences on the short-term stock return reversal and continuance anomaly in the Hong Kong stock market. We confirm that winner stocks behave differently from loser stocks in that the return reversal phenomenon is pervasive within past winner stocks only while past loser stocks tend to show weak return continuance. The arbitrage strategy can earn significantly positive contrarian profits, especially for small firms and illiquid stocks. The anomaly varies across different industries and is also sensitive to the market movement. Despite the existence of the anomaly, our results still in general suggest that the Hong Kong stock market is weak-form efficient because arbitrage trading costs would largely overwhelm the available profits in most cases.     

Cattle as a consistently resilient agricultural commodity

This study compares a range of agricultural commodities over periods of varying economic circumstances. These commodities are examined over three categories, including returns, risk, and contribution to portfolio optimisation. Consistency in these categories is determined over four equal three-year stages which comprise pre-GFC (Global Financial Crisis), GFC, post-GFC and post-post GFC. To demonstrate resilience in the most extreme circumstances, the study uses Conditional Value at Risk (CVaR), which measures extreme risk in the tail of a distribution, as the risk measure and risk-return optimiser. The study thus provides a unique and comprehensive extreme-risk based focus which identifies and ranks the consistency of performance of agricultural commodities over a range of criteria and conditions. Cattle commodities consistently demonstrate the strongest overall performance in the categories examined.     

Attitude and Willingness to Pay for National and Store Brands of Milk in the South of Chile

ABSTRACT

In Chile the milk consumption has maintained between 124 and 134 Ls per capita since 1996. To determine the attitude and willingness to pay for national and store brands of fluid milk in the south of Chile, a survey of 400 people was conducted. A conjoint analysis determined that the consumers experienced a positive reaction toward two national brands (traditional and those emergent in the market) and expressed negative reaction to a store brand. The consumers were determined to pay lower prices in relation to the market value for the store brand and higher prices for national brands.     

Consumers’ Intent: In the Organic Food Market

ABSTRACT

This paper examines the determinants that influence consumers' intention to purchase organic products. Ajzen's theory of planned behaviour (TPB) provides the conceptual framework of the research and the appropriateness of the theory is tested. A survey of 144 consumers was used to determine the beliefs which determine consumers’ intent to purchase organic food. Furthermore, attitudes, subjective norm, and perceived behavioral control were examined to determine whether they affect consumers’ intention to make organic products purchases. The findings offer considerable support for the robustness of the TPB in explaining intention in the sample. In addition, empirical evidence suggest that price, availability of organic products, product information and the subjective opinions of others are important determinants of consumers intent to buy organic products. The results are consistent with previous research.     

Mergers and Acquisitions and Market Volatility of Brazilian Banking Stocks: An Application of GARCH Models

The main objective of this research was to investigate the impacts caused by announcements of mergers and acquisitions (M&As) on the volatility of the returns of Brazilian bank stocks from 1994 to 2015. In order to achieve the proposed objective, this study applied Generalized Autoregressive Conditional Heteroscedastic (GARCH) class models to the series to model their volatility. Our results confirmed the impact of the announcement of M&As on volatility. They suggest that M&A announcements are expected to cause a negative reaction if related to an expansion or a deal involving a less-well known bank, and a positive reaction if it involves well-known bank with good reputation—a higher level of confidence and a lower level of information asymmetry for investors.     

Understanding consumers' online conversation practices in the context of convenience food

The area of convenience food has become an insightful context for studying consumption because it is full of tensions and contradictions. This context has attracted an ample amount of research on buying motivations, consumer attitudes and preferences. However, the practices of consuming convenience food have remained a rather unexplored area of research. The purpose of this study is to identify and dissect consumers' online conversation practices related to convenience food. Consequently, the study uses a practice theoretical approach to analyse consumers' online conversations about the topic. Three different categories and nine different practices within them are identified. The practices are further dissected to reveal their tension‐increasing and tension‐relieving characteristics. Finally, the article draws conclusions regarding practice theory and convenience food consumption.     

Foreign Direct Investment in Sub-Saharan Africa: Motivating Factors and Policy Issues

Sub-Saharan Africa's (SSA) foreign direct investment (FDI) share has persistently averaged 1% of global flows. The location decision and perceptions of investors are therefore instructive for policy making. This article factor analyses a survey of perceptions, operations, and motivations of 758 foreign investors in 10 SSA countries. We find that the provision of transaction cost–reducing information on industries and markets and utility services to investors before and after a firm's FDI decision are significant factors. FDI location decision in SSA is influenced strongly by political economy considerations. Labor and production input variables are not influential.     

“Greening” the marketing mix: do firms do it and does it pay off?

Growing concern about the sustainability of the natural environment is rapidly transforming the competitive landscape and forcing companies to explore the costs and benefits of “greening” their marketing mix. We develop and test a theoretical model that predicts (1) the role of green marketing programs in influencing firm performance, (2) the impact of slack resources and top management risk aversion on the deployment of such programs, and (3) the conditioning effects that underpin these relationships. Our analyses show that green marketing programs are being implemented by firms, and we find evidence of significant performance payoffs. Specifically the results indicate that green product and distribution programs positively affect firms’ product-market performance, while green pricing and promotion practices are directly positively related to firms’ return on assets. In addition, industry-level environmental reputation moderates the links between green marketing program components and firms’ product-market and financial performance. Finally, we find that slack resources and top management risk aversion are independently conducive to the adoption of green marketing programs—but operate as substitutes for each other.
