Value creation and value capture under moral hazard: Exploring the micro-foundations of buyer– supplier relationships

Abstract: We combine the formalism of a principal–agent framework with a value-based analysis in order to investigate the micro-foundations of business partner selection and the division of value in contracting relationships. In particular, we study how the key contracting parameters such as efficiency, transactional integrity, incentive alignment, and gaming affect outcomes when buyers face competing suppliers. We show that integrity and efficiency increase value creation and capture for all parties and are complements. While incentive gaming is unambiguously bad for value creation, and reduces buyers' value capture, it can benefit some suppliers. For alignment, we find that neither party has an incentive to use fully aligned performance measures that maximize total value creation. We conclude by analyzing buyers' and suppliers' incentives to invest in integrity

Consumer research on sales promotions: A state‐of‐the‐art literature review∗

Abstract: Many research traditions have dealt with consumer psychology and behaviour vis‐a‐vis sales promotions The consumer‐oriented approach seeks to identify the heavy users of promotions and to track their purchasing strategies involving the choice of a promoted brand The aim of the theory‐oriented research traditions is to test the explanatory power of various cognitive, attitudinal, behavioural and economic frameworks, be it to explain why and how consumers react to sales promotions or to understand when companies should promote This article exposes the specificity of each research tradition, its principal results and the most promising areas for future research

Negative association, ordering and convergence of resampling methods

Abstract: We study convergence and convergence rates for resampling schemes. Our first main result is a general consistency theorem based on the notion of negative association, which is applied to establish the almost sure weak convergence of measures output from Kitagawa’s [J. Comput. Graph. Statist. 5 (1996) 1–25] stratified resampling method. Carpenter, Ckiffird and Fearnhead’s [IEE Proc. Radar Sonar Navig. 146 (1999) 2–7] systematic resampling method is similar in structure but can fail to converge depending on the order of the input samples. We introduce a new resampling algorithm based on a stochastic rounding technique of [In 42nd IEEE Symposium on Foundations of Computer Science (Las Vegas, NV, 2001) (2001) 588–597 IEEE Computer Soc.], which shares some attractive properties of systematic resampling, but which exhibits negative association and, therefore, converges irrespective of the order of the input samples. We confirm a conjecture made by [J. Comput. Graph. Statist. 5 (1996) 1–25] that ordering input samples by their states in $\mathbb{R}$ yields a faster rate of convergence; we establish that when particles are ordered using the Hilbert curve in $\mathbb{R}^{d}$, the variance of the resampling error is ${\scriptstyle\mathcal{O}}(N^{-(1+1/d)})$ under mild conditions, where $N$ is the number of particles. We use these results to establish asymptotic properties of particle algorithms based on resampling schemes that differ from multinomial resampling.

Nonseparable Preferences, Fiscal Policy Puzzles, and Inferior Goods

Abstract: Nonseparable preferences over consumption and leisure can generate an increase in private consumption in response to government spending, as found in the data, in a frictionless business cycle model. However, the conditions on preferences required for these result to obtain hold if and only if the consumption good is inferior. Similarly, positive co-movement of consumption and hours worked occurs if and only if either consumption or leisure is inferior.

International evidence on the impact of adopting English as an external reporting language

Abstract: This study investigates the economic consequences of non-English-speaking companies adopting English as an external reporting language. We examine a sample of European companies that initiate the voluntary issuance of an annual report in English in addition to the local language annual report. To control for self-selection, we use a difference-in-differences design with a propensity score matched control sample. We find that adoption of English as an external reporting language is associated with increased foreign ownership, decreased information asymmetry, and increased analyst following. We also find that these benefits are not conditional on the use of IFRS for financial reporting. Our findings hold if we run a number of robustness checks to control for correlated events (creation of an investor relations service, provision of conference calls, and/or changes in management). These results are consistent with the language used in the annual report acting as a barrier to investment for some investors and with annual reports issued in English reducing investors’ information processing costs.
