Innovating out of the Fishmeal Trap: The role of Insect-Based Fish Feed in Consumers’ Preferences for Fish Attributes

The purpose of the study was to examine the potential market impacts of the use of insect-based protein for fish feed as an innovative approach out of the fish-meal trap. An online questionnaire was used to elicit information on fish consumption choices among 610 German consumers using a Discrete Choice Experiment. Mixed logit and latent class logit models were used to model consumers’ preference heterogeneity. Results showed, that consumers’ preferences for fish attributes such as filets, freshness, ecolabelling and domestic production are heterogeneous and important in consumption choices. The minor share of the respondents was sensitive, while the remaining was indifferent regarding the use of insect based protein as feed in trout production. For this sensitive segment, consumption would be expected to be reduced unless the price is reduced or other attributes such as convenience aspects are improved. The implication is that firms can substitute without a significant impact on the market demand given that the majority of consumers are indifferent regarding feed sources for trout production. As a result, it provides an innovative way to ensure sustainable use of resources and reduces the threat of fish meal trap while reducing pressure on the already over-exploited marine life. The results provide first insights into the market impact of using insects in the animal protein value chain. It is important especially with Europe’s recent lift of the ban on using insect-based protein in the animal food industry

Public Preferences and Values for Rural Land Preservation in Florida

This study develops a method to evaluate the influence of local geography on respondents values for land conservation programs. The study employs a choice experiment to evaluate alternative conservation plans. Results indicate that residents local landscapes do matter to the estimated values for such conservation programs. Our results also provide information about the divergence of political and economic jurisdictions for land conservation programs in Florida.Land Economics/Use,

Revisiting the Economics of Privacy: Population Statistics and Confidentiality Protection as Public Goods

This paper has been replaced with http://digitalcommons.ilr.cornell.edu/ldi/37. We consider the problem of the public release of statistical information about a population–explicitly accounting for the public-good properties of both data accuracy and privacy loss. We first consider the implications of adding the public-good component to recently published models of private data publication under differential privacy guarantees using a Vickery-Clark-Groves mechanism and a Lindahl mechanism. We show that data quality will be inefficiently under-supplied. Next, we develop a standard social planner’s problem using the technology set implied by (ε, δ)-differential privacy with (α, β)-accuracy for the Private Multiplicative Weights query release mechanism to study the properties of optimal provision of data accuracy and privacy loss when both are public goods. Using the production possibilities frontier implied by this technology, explicitly parameterized interdependent preferences, and the social welfare function, we display properties of the solution to the social planner’s problem. Our results directly quantify the optimal choice of data accuracy and privacy loss as functions of the technology and preference parameters. Some of these properties can be quantified using population statistics on marginal preferences and correlations between income, data accuracy preferences, and privacy loss preferences that are available from survey data. Our results show that government data custodians should publish more accurate statistics with weaker privacy guarantees than would occur with purely private data publishing. Our statistical results using the General Social Survey and the Cornell National Social Survey indicate that the welfare losses from under-providing data accuracy while over-providing privacy protection can be substantial

Strengthening Community Foundations - Redefining the Opportunities

Commissioned by the Council on Foundations and released in October 2003, this white paper details the findings and the implications of our study of costs and revenues at nine community foundations. Offering a new perspective for community foundation sustainability, the white paper proposes that community foundations examine their strategy and operations on a product-by-product basis, taking into account their mission-driven priorities, internal costs, customer preferences and the competing donor alternatives for each type of product or service they offer

One size does (obviously not) fit all: Using product attributes for wine market segmentation

The intense competition affecting the wine industry in recent decades has forced wineries and retailers to reshape their marketing strategies on the basis of consumer preferences. The current study aims to identify such preferences and the effects they might have in influencing consumer decisions. Preferences for different wine attributes as well as the psychographic traits of respondents were revealed through a web-based questionnaire administered to 504 wine consumers living in the wider metropolitan area of New York. Best-worst scaling (BWS) was used to detect consumer preferences for eleven wine attributes. Based on individual best-worst scores, a latent class segmentation analysis was implemented to classify consumers into four segments on the basis of psychographic characteristics such as involvement, subjective knowledge, innovativeness and loyalty proneness. The four segments identified (i.e. experientials, connoisseurs, risk minimizers and price-sensitive) differ significantly in terms of their preferences towards wine and psychographic characteristics, suggesting that a mass marketing approach is no longer suitable. Accordingly, managers need to adapt their marketing strategies to meet the preferences of different target groups. The results provide broad implications for marketers, wineries and retailers interested in successfully targeting consumers in a highly competitive market

Acquisition Activity in the United Kingdom: Parametric and Semi-Parametric Estimation

In this article we attempt to identify the nancial characteristics of takeover targets in UK using the period 1982-1990. The study analyses the relationship between bidders and targets, and targets and non-targets over two distinct sub-periods, 1982-1985 and 1986-1990 which are viewed as being homogenous. The rst period followed a deep recession which followed a distinct shift in Macroeconomic Policy after 1979. The second period was associated with nancial liberalisation in 1986 and the freeing up of Monetary policy that followed the Stock Market Crash in 1987. To facilitate this analysis, two bi-variate Logit models are estimated over each sub-period and over the period as a whole. The above models are used to test whether Merger and Acquisition behaviour has changed by under- taking a Likelihood Ratio based analogue of the Chow test. A General Modelling strategy is adopted to select variables as a mechanism for pre- cluding inconsistency and reducing the impact of collinearity. Comparison is also made with a semi-parametric estimator

Measurement in marketing

We distinguish three senses of the concept of measurement (measurement as the selection of observable indicators of theoretical concepts, measurement as the collection of data from respondents, and measurement as the formulation of measurement models linking observable indicators to latent factors representing the theoretical concepts), and we review important issues related to measurement in each of these senses. With regard to measurement in the first sense, we distinguish the steps of construct definition and item generation, and we review scale development efforts reported in three major marketing journals since 2000 to illustrate these steps and derive practical guidelines. With regard to measurement in the second sense, we look at the survey process from the respondent's perspective and discuss the goals that may guide participants' behavior during a survey, the cognitive resources that respondents devote to answering survey questions, and the problems that may occur at the various steps of the survey process. Finally, with regard to measurement in the third sense, we cover both reflective and formative measurement models, and we explain how researchers can assess the quality of measurement in both types of measurement models and how they can ascertain the comparability of measurements across different populations of respondents or conditions of measurement. We also provide a detailed empirical example of measurement analysis for reflective measurement models

ASSESSING IMPACTS OF ENVIRONMENTAL CHANGE ON ABORIGINAL PEOPLE: AN ECONOMIC EXAMINATION OF SUBSISTENCE RESOURCE USE AND VALUE

The report describes the research design, data collection and preliminary analysis of an economic assessment of non-timber resource use by Aboriginal People in Northwest Saskatchewan. The project is designed to develop methods of valuing resource use by Aboriginal People so that these values can be incorporated into forest resource management decisions and to evaluate the impact of forest management actions on the economic well-being of Aboriginal People living in the region. Data on non-timber resource use are collected and spatially explicit economic models are developed in order to construct estimates of behavioral change and value associated with changes in the environment and landscape (through forestry, access, or other landscape changes).Environmental Economics and Policy, Resource /Energy Economics and Policy,
