Determinants of Participation and Response Effort in Web Panel Surveys

Web panels are widely employed to conduct marketing research surveys, yet little is known regarding why consumers join web panels or participate in web surveys. The present research investigated the effects of individuals' motivational traits on whether they joined web panels, participated in surveys upon joining, and the effort they put into their responses. A longitudinal study employing population profiling gathered personality measures from the entire population of potential panelists (N = 751) and invited them to join a web panel. Those accepting (N = 503) were sent a series of six marketing research surveys. Results revealed that consumers' need for cognition, curiosity, agreeableness and extraversion were significant predictors of joining the web panel. The first three traits also predicted survey participation, as did openness to experience. Among participants, response effort was affected the greatest by curiosity, extraversion, and conscientiousness. An additional experiment, conducted with 327 participants, ruled out a selection bias explanation for some results. These findings provide useful insights to researchers using web panels, and point out limitations with using strictly demographics-based weighting schemes when selecting web panels.     

Volatility in Oilseeds and Vegetable Oils Markets: Drivers and Spillovers

Food price volatility has re‐emerged as an important topic of political discussion since the food price crisis of 2007–2008. Different volatility drivers have been identified for different markets in the theoretical and empirical literature. However, there is no comprehensive analysis that considers a large number of potential drivers and investigates their joint effects in a dynamic model of interrelated markets. Our study provides such a volatility analysis for the oilseeds and vegetable oils markets. We use a common GARCH approach and a VAR model to identify volatility drivers and spillover effects. Our results show that exchange rate volatility is very important. However, the hotly debated financialisation of commodity markets is not found to be volatility increasing in our monthly data. Impulse response functions show strong spillover effects. Because many volatility drivers found to be important in other markets have no significant effect in our study, our results suggest that volatility drivers are market specific. This implies that any volatility‐reducing policies need to be designed for the market in question.     

Are French consumers ready to pay a premium for eco‐labeled seafood products? A contingent valuation estimation with heterogeneous anchoring

Could the future French eco‐label for fresh seafood products find its place in the French market? This study employs a contingent valuation method to estimate French consumers’ willingness‐to‐pay (WTP) for eco‐labeled fresh seafood products. We exploit original data from a survey carried out in 2010, where 626 participants responded to a double‐bounded dichotomous choice model, through an ascending or descending bid system. Controlling for shift and anchoring effects in random effect probit models, we significantly improve estimation of WTP and its determinants for the three species studied (monkfish, lobster, sole), in particular when using heterogeneous anchoring. We show that WTP is positively correlated to respondents’ income, and also to their environmental concern, to living alone, to living far from the coast, and to trusting NGOs or public institutions more than producer organizations to implement an eco‐label. We also show that the mean price premiums do not differ between species. Finally, on average, the maximum premium consumers accepted to pay is approximately 10% of the product price.     

Domestic Crop Booms,Livelihood Pathways and Nested Transitions: Charting the Implications of Bangladesh's Pangasius Boom

Rapidly transforming Asian food systems are oriented largely towards domestic markets, yet literature on Asian crop booms deals almost exclusively with commodities produced for export. With reference to pangasius aquaculture in Bangladesh, we argue that ‘domestic crop booms’ – agricultural booms driven by domestic demand – are contributing to rapid social and ecological transformations in Asia and across the globe. We adopt a comparative multi‐scalar approach, and develop the concept of ‘livelihood pathways’ as a means of understanding agrarian change associated with crop booms. The study reveals sharply divergent patterns of social change resulting from the pangasius boom, as experienced in two different village settings, despite underlying similarities in the processes of commodification evident in both. In addition to drawing attention to domestic crop booms and the diversity of transitions in which they result, the paper demonstrates the value of comparative multi‐scalar analytical approaches and the importance of livelihood pathways in processes of agrarian change.     

Markttransparenz und Geheimwettbewerb? Das Beispiel Rohmilchmarkt

Das Bundeskartellamt hat sich im Juni 2011 mit Marktinformationssystemen auf dem Rohmilchmarkt besch?ftigt und die Auffassung vertreten, dass auf diesem Markt eine zu hohe Markttransparenz herrsche. Dies reduziere den für einen funktionierenden Markt erforderlichen Geheimwettbewerb. Dem widersprechen die Autoren, da die Besonderheiten des Rohmilchmarktes gegen eine Einschr?nkung der Transparenz sprechen. Zunehmende Transparenz durch bessere Preisvergleichsm?glichkeiten im Internet stellt den Grundsatz des Geheimwettbewerbs auch auf anderen M?rkten in Frage.     

How wages and employment adjust to trade liberalization: Quasi-experimental evidence from Austria

We study the response of regional employment and nominal wages to trade liberalization, exploiting the natural experiment provided by the opening of Central and Eastern European markets after the fall of the Iron Curtain in 1990. Using data for Austrian municipalities, we examine differential pre- and post-1990 wage and employment growth rates between regions bordering the formerly communist economies and interior regions. If the ‘border regions’ are defined narrowly, within a band of less than 50 km, we can identify statistically significant liberalization effects on both employment and wages. While wages responded earlier than employment, the employment effect over the entire adjustment period is estimated to be around three times as large as the wage effect. The implied slope of the regional labor supply curve can be replicated in an economic geography model that features obstacles to labor migration due to immobile housing and to heterogeneous locational preferences.
