Trends in Service Sourcing Practices

This paper identifies 12 current trends in sourcing practices in general and explores whether these trends are relevant for service sourcing in particular. Based on interviews with sourcing managers, it is, for example, concluded that service sourcing is becoming more systematic, formalized, and globalized with greater demands for trained staff, high-tech tools and focus on CSR. The authors have contributed equally to the article and appear in alphabetical order. The authors would like to express their gratitude to the respondents who made the study possible.     

Delegation and Incentives under Evolutionarily Stable Conjectures

Existing results show that in a homogenous Cournot duopoly, commitment by delegation harms profit. This conclusion presupposes that market conduct is the same whether incentives are aggressive or accommodating. We study delegation and incentives under evolutionarily stable conjectures and show how performance pay co‐determines market conduct. In fact, in equilibrium with evolutionarily stable conjectures, we show that commitment through delegation leads to a profit increase. Manipulation of managerial incentives produces less competition and therefore benefits firms' owners even in symmetric homogenous oligopoly. Copyright © 2016 John Wiley & Sons, Ltd.     

From dollarisation to euroisation

In the past the dollar has been so dominant as an international currency that the term ‘dollarisation’ has become a synonym for currency substitution, i.e. the voluntary use of a foreign currency instead of the respective country's own legal tender. This article addresses the question as to whether the euro may be expected to partly replace the US currency in this function, focusing on the former's use as a substitution currency in countries on the periphery of the euro zone. Some policy conclusions are drawn for both the ‘euroised’ economies and Euroland.     

The Spatial Integration of Paddy Markets in Vietnam

This paper examines whether there is spatial integration between and within paddy markets in the north and south of Vietnam. The empirical model developed uses estimates of transfer costs to generalise Ravallion's model of spatial market integration to allow for threshold effects. A sequential testing strategy is used to test for market segmentation, the number of thresholds, long‐run integration, informational efficiency and the Law of One Price within an error‐correction framework. We find neither threshold effects nor weak evidence of paddy market integration between northern and southern Vietnam. There is, however, evidence of both threshold effects and stronger market integration within the Red and Mekong River deltas. Whenever price spreads exceed their thresholds, at least 60% of price changes are transmitted between regional markets within a month. Nonetheless, the instantaneous version of the Law of One Price only holds for a few regimes and market pairs. These results suggest that national level policies cannot be relied upon to stabilise or support paddy prices in Vietnam. Instead, policies need to be designed with the specific production, consumption and marketing characteristics of northern and southern Vietnam in mind.     

Using crowdsourced data to analyze transport crime

ABSTRACT

Anecdotal evidence suggests that harsh social conditions in the road haulage industry are having an impact on transport crime. This paper analyses transport crime, and demonstrates how to use a combination of official statistics and crowdsourced data in the process. A hierarchical regression analysis was applied to investigate the relations among different factors in order to predict transport crime threats. A secondary data set on transport crime from the Swedish Police was combined with primary crowdsourced data from volunteer observations of trucks in Sweden from both high-wage and low-wage countries. The findings imply that transportation is more vulnerable to antagonistic threats in geographical areas where the low-wage hauliers operate more frequently. For policymakers and practitioners, these findings provide useful guidance for the planning of security measures. To the authors’ knowledge, this paper is the first exploratory study of its kind that uses a combination of official statistics and crowdsourced data.     

Adoption of multiple electronic marketplaces: Antecedents from a grounded theory study

To achieve economies of scope, most motor carriers combine long-term contracts with shippers and brokers with periodic spot assignments found on electronic marketplaces (EMs). While previous research has addressed how carriers adopt an EM, we know little about factors that influence carriers to adopt multiple EMs. Given the rise of the platform economy of the trucking industry, we chose to address this gap and generate mid-range theory on adopting multiple EMs in a logistics context. To do this, we applied grounded theory and conducted 23 interviews with motor carriers and EM experts in North America and Europe until we reached theoretical saturation. Our findings reveal that many motor carriers adopt a portfolio of different EMs, and that their awareness of platforms, expected and realized benefits, attitude, and vigilance determine how they configure their EM portfolios. The implication for existing theory is that, while previous studies depicted EM adoption from a single-system perspective, we found that it is actually a continuous selection process that follows a portfolio perspective. Our paper also has implications for practice in that it illuminates the rationales behind EM portfolio development and identifies actionable factors that can help managers configure stronger portfolios.     

Dimensionality reduction in forecasting with temporal hierarchies

Combining forecasts from multiple temporal aggregation levels exploits information differences and mitigates model uncertainty, while reconciliation ensures a unified prediction that supports aligned decisions at different horizons. It can be challenging to estimate the full cross-covariance matrix for a temporal hierarchy, which can easily be of very large dimension, yet it is difficult to know a priori which part of the error structure is most important. To address these issues, we propose to use eigendecomposition for dimensionality reduction when reconciling forecasts to extract as much information as possible from the error structure given the data available. We evaluate the proposed estimator in a simulation study and demonstrate its usefulness through applications to short-term electricity load and financial volatility forecasting. We find that accuracy can be improved uniformly across all aggregation levels, as the estimator achieves state-of-the-art accuracy while being applicable to hierarchies of all sizes.     

Dark is durable,light is user-friendly: The impact of color lightness on two product attribute judgments

Visual design elements such as color do not only provide aesthetic appeal; they also convey information that consumers rely on when making unrelated product attribute judgments. Seven experiments reveal that consumers assess darker-colored products to be more durable but less user-friendly than lighter-colored ones. Both outcomes are linked to the influence of color lightness on perceived weight, but the latter outcome appears to be more easily disrupted than the former one. Specifically, the impact of color lightness on user-friendliness assessments, but not on durability assessments, is eliminated when the role of weight is unclear or when cognitive load is induced. However, consumers make greater downward adjustments in their durability assessments after physically handling a product with darker (vs. lighter) color. These findings highlight some of the potential complexities and nuances in consumer responses to color.
