Food choice models and their relation with food preferences and eating frequency in the Polish population: POFPRES study

A sample of 9339 subjects aged 13–75, living in the six macro-regions of Poland rated the preferences of 140 various food products, eating frequency and factors influencing food choice. Four groups of consumers were found: “consumers susceptible to advertising and seeking novel healthy products” (33.2% of the sample), “consumers not taking care of their health” (25.4%), “consumers not susceptible to advertising and taking care of their health” (32.5%), and “consumers insensitive to sensory attributes of fruit and vegetables” (9.0%). Among factors influencing the food choice, sensory and functional factors were significant, and health and price – moderate. Advertising was generally denied as an important factor in food choice. The food choice motives were highly dependent on age and gender, and to a lower extent – on region of residence, size of place of residence, economic condition and education level. Women/girls more often showed pro-health behaviours in food choice, choice motives, preferences and food intake.

Technological knowledge assets in industrial firms

This research focuses on identifying and measuring the technological knowledge assets that constitute the basis of the knowledge management process and on the study of contextual factors that determine their use. To that end, a longitudinal study of 1,444 Spanish industrial firms between 1998 and 2000 was conducted using information gathered by the Survey of Business Strategies. The results enable us to identify technological knowledge assets with different levels of codification and to have a general view of how age, size and sector affect the use of those assets by Spanish industrial firms.     

Efectos de las remesas de migrantes mexicanos en el Canadá en las explotaciones agrarias mexicanas

Con datos de una encuesta a participantes en el Programa de Trabajadores Agrícolas Temporales México‐Canadá, los autores estiman un modelo de ecuaciones simultáneas de mínimos cuadrados ordinarios y encuentran que las remesas impulsan las inversiones agrícolas en México, que a su vez incrementan los ingresos agrícolas. También observan una influencia positiva de las remesas en los ingresos no agrícolas en México, ya que permiten a los encuestados emprender y diversificar sus inversiones. Ello refrenda la teoría de la «nueva economía de la migración laboral», según la cual las remesas contribuyen al desarrollo económico al compensar la falta de créditos en la función de inversión de las explotaciones agrarias familiares.     

Innovation and productivity in family firms: evidence from a sample of European firms

ABSTRACT

Using firm-level data, we estimate the returns to R&D investments for a sample of European manufacturing firms over the period 2007–2009. Results confirm that R&D efforts are positively related to productivity regardless of firm type (family or nonfamily firms). Additionally, we find that family firms invested more in R&D than nonfamily firms, but the returns to their R&D investments are low, emphasizing that they have a lower capacity to translate R&D investments into economic gains.     

The Productivity Commission Inquiry Report into Mental Health—A Commentary from a Health Economics Perspective

The Productivity Commission's Inquiry Report into Mental Health makes extensive recommendations to improve population mental health as a means of further enhancing productivity and economic growth. While providing an invaluable high‐level vision for reforming current mental health and social systems at a programmatic level, it lacks supporting evidence that would guide implementation of specific recommendations. We discuss important methodological considerations used to measure the output of the mental health sector and present clinical and cost‐effectiveness evidence, supporting selected recommendations. We suggest the development of a broad‐based health technology assessment process to facilitate consistent decision making across health and other government sectors.     

The effectiveness of movie trailer advertising

Prior to a movie release in theaters, trailer advertising provides valuable information that can help viewers and investors form expectations about the movie's future success. While previous research has looked at the financial implications of movie advertising budgets, the effects of trailers' creative characteristics on abnormal returns have not yet been investigated. Using a sample of movie trailers, results from our event study and cross-sectional analysis show that the appeal of the movie plot revealed in the trailer, the number of scene cuts and the inclusion of violent, sexual, or humorous scenes influence the movie's abnormal returns. However, the use of special effects in the movie trailer does not impact investors. Results also suggest that investors react more strongly to first than to follow-up trailers released for the movie, and that early release of the first positively impacts the movie's returns.     

Consumer surplus and the reform of network industries: a primer

Starting from an industry where production is provided by a public monopolist, we observe the effects of a sequence of reforms within the network industry on consumer surplus. Using a simple comparative statics framework, we find the indifference conditions for the consumer surplus under the following regimes: a public monopoly, an unregulated private monopoly, a regulated private monopoly, a vertically disintegrated monopoly, a duopoly and a liberalized market. The results are determined by the relative size of the x-inefficiencies of the public monopolist, allocative inefficiencies of the private monopoly, the cost of unbundling and the costs related to establishing a competitive market.     

The evolution of conventions in minimum effort games

The literature on minimum effort game has been concerned with a symmetric game with linear payoff functions. The main aim of the present paper is to study the coordination problem arising in a not necessarily symmetric minimum effort game with two players. The sources of asymmetry can be twofold: the productivity of effort and the distribution of the join output. To select among the Pareto ranked equilibria we use the stochastic stability criterion. We show that, for any configuration parameters, the set of stochastically stable equilibria coincides with the set of potential maximizers. We also show that when the disutility of effort is linear, the Pareto dominant equilibrium is stochastically stable provided that the distributive parameter belongs to a well defined range. When the disutility of effort is nonlinear no distributive arguments can be used to successfully affect the selection process. Lastly we prove that the connection between stochastic stability and maximum potential can fail when more than two agents are considered.     

Is sustainable tourism an obstacle to the economic performance of the tourism industry? Evidence from an international empirical study

Sustainability has become an important strategic objective for tourism destinations worldwide. All analytical tourism competitiveness models make direct or indirect positive references to sustainability. It is accepted that sustainable tourism can reduce resource costs and help create market differentiation. Nevertheless, it has traditionally been considered that, short term, sustainability measures can reduce profitability and compromise competitiveness. Debates on the progress, implications, and practicality of sustainable tourism remain open. The relationship between economic sustainability, and environmental and sociocultural sustainability, is a central but largely unresearched area for tourism scholars, especially at the macro level. This study explores that difficult but essential area, using the World Economic Forum's empirical evidence from 128 countries, backed by the economic data search tool of the World Travel & Tourism Council. It demonstrates that progress in tourism sustainability does not affect a country's main economic tourism indicators in the short term, and does not constrain profitability and competitiveness. It also finds that sustainable tourism is not a luxury that only rich countries can afford, nor should it prevent development and perpetuate poverty in developing countries. An effective marketing and communication program about sustainable tourism is, however, found to be essential for economic success.
