The Causes and Consequences of Accelerated Stock Repurchases

We examine the choice between accelerated share repurchase (ASR) and open market repurchase (OMR) as repurchase mechanisms between 2004 and 2007. For a sample of ASRs and OMRs that actually buy shares in the announcement quarter, we find that ASR firms have lower market‐to‐book ratios, less cash, but greater managerial entrenchment. Prior to repurchase, ASR firms are subject to significantly more takeover rumors than OMR firms are, and this, along with entrenchment and undervaluation, affects the choice to use ASRs. ASR firms experience positive average abnormal returns both before and after the announcement. Moreover, the latent takeover probability is significantly lower for both ASR and OMR firms (when compared with pre‐announcement levels), but the reduction for ASR firms is more pronounced. Our results suggest that repurchases, and especially ASRs, indeed make a firm a less attractive prospect for takeover.     

Predicting Consumer Avoidance of Native Advertising on Social Networking Sites: A Survey of Facebook Users

Abstract

As a result of constant efforts to improve consumers’ online advertising experiences, native advertising has started to gain popularity on social networking sites (SNSs). This survey study examined antecedents of avoidance of native advertising on SNSs and the moderating role of consumer skepticism toward native advertising. Our findings suggest perceived intrusiveness and perceived informative and entertainment advertising value as major antecedents of consumer advertising avoidance. Additionally, the number of brands that consumers are following on SNSs and negative communication among peers on SNSs were found to be factors affecting native advertising avoidance. Finally, consumer skepticism toward native advertising was found to be an important moderating variable in the mechanism of advertising avoidance on SNSs.

Arrow–Debreu equilibria for rank‐dependent utilities with heterogeneous probability weighting

We study Arrow–Debreu equilibria for a one‐period‐two‐date pure exchange economy with rank‐dependent utility agents having heterogeneous probability weighting and outcome utility functions. In particular, we allow the economy to have a mix of expected utility agents and rank‐dependent utility ones, with nonconvex probability weighting functions. The standard approach for convex economy equilibria fails due to the incompatibility with second‐order stochastic dominance. The representative agent approach devised in Xia and Zhou (2016) does not work either due to the heterogeneity of the weighting functions. We overcome these difficulties by considering the comonotone allocations, on which the rank‐dependent utilities become concave. Accordingly, we introduce the notion of comonotone Pareto optima, and derive their characterizing conditions. With the aid of the auxiliary problem of price equilibria with transfers, we provide a sufficient condition in terms of the model primitives under which an Arrow–Debreu equilibrium exists, along with the explicit expression of the state‐price density in equilibrium. This new, general sufficient condition distinguishes the paper from previous related studies with homogeneous and/or convex probability weightings.     

Monetary and Financial Cooperation Between China and the One Belt One Road Countries

ABSTRACT

Based on the theory of optimal currency area (OCA), we calculate the OCA index between China and the OBOR partners with the expressed objective of identifying which partners exhibit monetary and financial compatibilities, and hence present the best potential in terms of cost and benefits. Our findings suggest that among South East Asia region, Malaysia exhibits the highest compatibility and profit potential, followed by Thailand and Vietnam. For the East European area, Poland and Croatia show the best potential in terms of monetary and financial cooperation; with the Czech Republic as close third. Based on our computation, currently Central Asia and the Middle East do not possess the condition or potential for beneficial financial and monetary collaboration.

Regional disparity of embedded carbon footprint and its sources in China: a consumption perspective

Carbon emission reduction could be achieved through extensive cooperation between relevant groups such as businesses, governments and consumers. Generally, carbon emissions stem from consumer behaviour. To tackle the increasingly serious energy crisis and climate change in China, it is thus vital to control carbon emissions generated by the country's urban consumers. From a consumption perspective, we utilize a self-organizing feature map model to analyse the spatial differentiation of per capita embedded carbon footprint (ECF) in urban China. We found that the spatial differentiation is significant with the per capita ECF of the east coastal area at a high level and that per capita disposable income is the key factor affecting ECF. Based on these findings, potential business opportunities to develop low-carbon products are discussed.     

A quantitative perspective of Porter's industry forces framework for investment analysis

Porter's industry forces framework is an important tool for external analysis of firms, but its qualitative nature presents numerous limitations to be used in investment analysis. This study introduces a quantitative perspective of the framework using financial information proxies. This allows investors to gauge the external factors quantitatively and to gain enhanced framework usability. In order to test its validity, the correlation movements of our quantitative perspective have been analysed. For demonstration of enhanced usability, our quantitative perspective, alongside machine learning models, was used to predict business performances. The empirical results indicate that our quantitative perspective of the framework corroborates with its original definition and that it exhibits enhanced usability than the original framework.     

GRADING JOURNALS IN ECONOMICS: THE ABCS OF THE ABDC

Many institutions and governments grade academic journals for the evaluation of research. In this paper, we implement a multi-bibliometric methodology for the evaluation of such a list of journal grades. We examine the grades assigned by the Australian Business Deans Council (ABDC) for over 750 journals in the fields of economics and statistics. Firstly, we generate up to 48 bibliometric-based grades for each journal based on the grade distribution implied by the ABDC. Secondly, we categorize the bibliometrics employing a cluster analysis of an interrater agreement statistic. Thirdly, we present a visualization of the consistency of the grading by journal. Finally, we list those journals where the majority of the matched bibliometrics indicate a higher or lower grade than their ABDC grade.
