“I like it,but I don't use it”: Impact of carsharing business models on usage intentions in the sharing economy

Carsharing is often promoted as a potentially environmental‐friendly alternative to individual car ownership. However, various carsharing programs have displayed limited success in the past. An initial field study of a new carsharing service is such a story of failure: The introduction of this new service at a medium‐sized German university generated unexpectedly low adoption rates so that the service was eventually scaled down and then suspended. Quantitative field study results as well as additional qualitative focus groups reveal that missing compatibility is a key barrier to adoption. Drawing on extant conceptual frameworks of user participation in sharing business models, a factorial survey identifies the importance of different dimensions of carsharing business models for their acceptance. The results reveal that a set of convenience and lifestyle dimensions influences usage intentions, including mode of drive, pickup and drop‐off mode, service level, price model, availability, and type of market mediation. In contrast, vehicle fleet does not appear to influence carsharing models' acceptance. These findings contribute to research on business model configuration as well as the attitude–behavior gap in the sharing economy by determining relevant dimensions of a carsharing business model that can bridge the gap between basically positive attitudes and usage resistance. Thereby, they also serve for concrete managerial recommendations.     

On the proportionality of EU spatial ex ante coexistence regulations: A comment

In their recent article in this journal, Demont et al. (2009) discuss the effects of alternative spatial ex ante coexistence regulations (SEACERs) in the context of the EU regulatory framework. We retain from Demont et al. (2009) that small pollen barriers should be considered as a possible regulatory option in all identifiable situations in which they are as effective as large isolation distances. This idea is in accordance with the proportionality principle of the 2003 EC Recommendation. But further analysis of how consumer choice and consumer welfare are affected should be conducted before supporting the idea that SEACERs should be flexible, that is that GMO farmers should always have the option of paying their non-GMO neighbours to implement the SEACERs in their own fields. We reject the authors’ argument that pollen barriers are necessarily more easily negotiable among neighbours (more “flexible”) than are isolation distances. We contest the relation of proportionality to the size of market signals for IP products. We contest the idea of shifting coexistence regulation from ex ante to ex post. We believe that any economic analysis of coexistence measures should include their welfare effects on consumers as well as on producers.     

Marketing survey research best practices: evidence and recommendations from a review of <Emphasis Type="Italic">JAMS</Emphasis> articles

Survey research methodology is widely used in marketing, and it is important for both the field and individual researchers to follow stringent guidelines to ensure that meaningful insights are attained. To assess the extent to which marketing researchers are utilizing best practices in designing, administering, and analyzing surveys, we review the prevalence of published empirical survey work during the 2006–2015 period in three top marketing journals—Journal of the Academy of Marketing Science (JAMS), Journal of Marketing (JM), and Journal of Marketing Research (JMR)—and then conduct an in-depth analysis of 202 survey-based studies published in JAMS. We focus on key issues in two broad areas of survey research (issues related to the choice of the object of measurement and selection of raters, and issues related to the measurement of the constructs of interest), and we describe conceptual considerations related to each specific issue, review how marketing researchers have attended to these issues in their published work, and identify appropriate best practices.

Stock Prices, Output and the Monetary Regime

Should monetary policy react to stock prices? The answer depends on whether stock prices are good predictors of future economic activity. Using long annual time-series data for the G-7 countries, data going back over 150 years for some countries, we find that stock prices do not systematically predict output growth regardless of the monetary regime in effect. We also find no evidence of a nonlinear relationship between stock prices and output except during the gold standard, when stock price booms and busts had some predictive power for output growth volatility.     

Estimating mortality rates: the role of proportional life expectancy

The computation of long-term survival is usually based on adjustments to the conventional life table. Assessing the validity of different types of adjustments can be difficult, partly because of the need to allow for two age-related trends-the decline in the average (normal) life expectancy, as well as in the new (abnormal) estimate. In this paper, we illustrate the value of routinely expressing each new estimate as a percentage of normal at each age. An additional finding has been that in some common disorders this proportional life expectancy (PLE) remains remarkably constant over many years.     

A method for calculating export supply and import demand elasticities

This article has a dual aim. First, it sets out to underline a learning-by-exporting effect in Spanish firms between 1991 and 2002. It further seeks to outline the conditions allowing firms to benefit from these spillover effects. Using a propensity score matching method, a group of firms having entered the export market (treatment group) is compared with a similar group of non-exporting firms (control group), and difference-in-differences regressions are carried out. The results show a cumulative productivity differential of 32% for the first four years of exporting, with continuous improvement in productivity. After three years of exporting, productivity gain is still approximately 10%. This study shows that increases in capacity utilisation and competitive pressure from foreign markets are insufficient to explain this causal link between exporting and total factor productivity (TFP). It is thus possible to deduce the presence of a learning-by-exporting effect, benefiting firms with sufficiently qualified employees and which are already engaged in international relations (due to foreign suppliers and/or foreign equity participation).     

“We make the shoes,you make the story” Teenage girls’ experiences of fashion: Bricolage,tactics and narrative identity

This article explores the ways that French teenage girls use fashion discourse to construct their evolving identity from their recently left childhood to their future as fully grown women. Verbatim texts of 14 phenomenological discussions concerning clothing, accessories, make‐up and fashion are interpreted using the concepts of bricolage (Lévi‐Strauss), tactics (Certeau) and narrative identity (Ric?ur). The findings resonate with Thompson and Haytko’s portrayal of a dialogical relationship between consumers and a system of countervailing fashion meanings and with Murray’s exposition of a dialectical and discursive tension between sign‐experimentation and sign‐domination. But beyond this we elucidate the process by which teenagers also acquire, from personal social milieu, skills and tactics through which they toy with preconstrained sartorial symbolism to construct the plot line of their own lives which, in turn, reflects their past, defines their present self and presages their future.     

Do we need deeper trade agreements for GVCs or just a BIT?

The paper investigates two policies geared towards stimulating and shaping global value chains (GVCs), namely deep regional trade agreements (DRTAs) and bilateral investment treaties (BITs). In an augmented gravity model, we test the impact of both policies on a variety of trade in value added indicators. We find that both policies are likely to increase GVC trade, although their transmission channels differ. While backward linkages are stimulated through both BITs and DRTAs, forward linkages respond only to DRTAs. The estimates suggest that negotiating a DRTA with investment provisions has a higher impact on trade in value added than signing a shallow RTA and a separate BIT.     

The HWWA econometric model for economic forecasts

Econometric models are often used to forecast economic developments. Does the use of computer-based econometric procedures help sharpen our view of the future or are we blinkered by the supposed ‘precision’ of such models? What problems arise when building national economic models and when these models are used for forecasting purposes? These issues are examined with reference to the HWWA model.
