An empirical comparison of the efficacy of covariance-based and variance-based SEM

Variance-based SEM, also known under the term partial least squares (PLS) analysis, is an approach that has gained increasing interest among marketing researchers in recent years. During the last 25 years, more than 30 articles have been published in leading marketing journals that have applied this approach instead of the more traditional alternative of covariance-based SEM (CBSEM). However, although an analysis of these previous publications shows that there seems to be at least an implicit agreement about the factors that should drive the choice between PLS analysis and CBSEM, no research has until now empirically compared the performance of these approaches given a set of different conditions. Our study addresses this open question by conducting a large-scale Monte-Carlo simulation. We show that justifying the choice of PLS due to a lack of assumptions regarding indicator distribution and measurement scale is often inappropriate, as CBSEM proves extremely robust with respect to violations of its underlying distributional assumptions. Additionally, CBSEM clearly outperforms PLS in terms of parameter consistency and is preferable in terms of parameter accuracy as long as the sample size exceeds a certain threshold (250 observations). Nevertheless, PLS analysis should be preferred when the emphasis is on prediction and theory development, as the statistical power of PLS is always larger than or equal to that of CBSEM; already, 100 observations can be sufficient to achieve acceptable levels of statistical power given a certain quality of the measurement model.     

Consumer stockpiling behavior in the retail gasoline market

ABSTRACT

I examine consumer stockpiling behavior in the retail gasoline market and factors that affect consumer stockpiling. Past research such as Hendel and Nevo (2006b Hendel, I. , and A.Nevo . 2006b. “Sales and Consumer Inventory.” The Rand Journal of Economics 37 (3): 543–561. doi:10.1111/(ISSN)1756-2171.[Crossref], [Web of Science ®] , [Google Scholar]) found evidence that implies stockpiling behavior. However, they did not observe actual inventory or consumption and have to rely on simplifying assumptions about these quantities. I collected a novel data set of gasoline purchase history of consumers with actual inventory and consumption to test several hypotheses that relate consumer stockpiling to price, duration between purchases, and consumption. I found that consumers purchase more gasoline when their inventory is low and those holding high inventory are more price sensitive. Consumption habits after a purchase may change due to two forces: previous consumption habit and purchase price. The exact change in consumption and duration between purchases depends on which force is stronger.

Analysis of the effects of visibility and warning devices on driver injury severity at highway-rail grade crossings considering temporal transferability of data

Abstract

This study explores the joint effect of visibility and warning devices on driver injury severity at the highway-rail grade crossings (HRGCs), while also considering other contributing factors. For this purpose, four mixed logit models are developed to estimate the determinants of driver injury severity considering the combinations of visibility conditions (daylight vs. no daylight) and type of warning devices (active vs. passive warning). The models were calibrated using the data obtained from the USDOT Federal Railroad Administration for HRGC crashes that occurred over a ten-year period 2008–2017 Federal Railroad Administration (FRA) Office of Safety Analysis. (2017). Accident data as reported by railroads. Retrieved July, 2018, from https://safetydata.fra.dot.gov/OfficeofSafety/publicsite/on_the_fly_download.aspx [Google Scholar] across the United States. A temporal transferability test was conducted and confirmed the stability of model specifications considering a ten-year span of collected data. The pseudo-elasticity analysis was conducted to ascertain marginal impact of the contributing factors on driver injury severity in each model. While the vehicle speed, train speed, time of day and driver age are found to be common significant factors among the four models, there are marked differences between parameters associated with various crash factors. The study provides new insight into the driver injury severity in train-vehicle collisions considering visibility and type of warning devices, which can help in setting up proper policies to improve safety at HRGCs.     

Bond Ratings and Income Smoothing in Brazil

ABSTRACT

In this article we use the variables proposed by Eckel (1981 Eckel , N. ( 1981 ). “The Income Smoothing Hypothesis Revisited.” Abacus , Vol. 17 , No. 1 , pp. 28 – 40 . [Google Scholar]) and Leuz et al. (2003 Leuz , C. , Nanda , D. , and Wysocki , P. ( 2003 ). “Earnings Management and Investors Protection: an International Comparison,” Journal of Financial Economics , Vol. 3 , No. 69 , pp. 505 – 527 . [Google Scholar]) as proxies to measure income smoothing and find that Brazilian companies that engage in this behavior receive better ratings in their public bond issues. Using data obtained from the National Bond Registration System and the Economatica, we evaluated public bond offerings. The results of univariate and multivariate analyses and robustness tests attest to the significance of the income smoothing factor, regardless of the rating agency. The results support the notion that income smoothing is an information-signaling mechanism and has an impact on bond ratings.

Small‐time,large‐time,and asymptotics for the Rough Heston model

We characterize the behavior of the Rough Heston model introduced by Jaisson and Rosenbaum (2016, Ann. Appl. Probab., 26, 2860–2882) in the small‐time, large‐time, and (i.e., ) limits. We show that the short‐maturity smile scales in qualitatively the same way as a general rough stochastic volatility model , and the rate function is equal to the Fenchel–Legendre transform of a simple transformation of the solution to the same Volterra integral equation (VIE) that appears in El Euch and Rosenbaum (2019, Math. Financ., 29, 3–38), but with the drift and mean reversion terms removed. The solution to this VIE satisfies a space–time scaling property which means we only need to solve this equation for the moment values of and so the rate function can be efficiently computed using an Adams scheme or a power series, and we compute a power series in the log‐moneyness variable for the asymptotic implied volatility which yields tractable expressions for the implied vol skew and convexity which is useful for calibration purposes. We later derive a formal saddle point approximation for call options in the Forde and Zhang (2017) large deviations regime which goes to higher order than previous works for rough models. Our higher‐order expansion captures the effect of both drift terms, and at leading order is of qualitatively the same form as the higher‐order expansion for a general model which appears in Friz et al. (2018, Math. Financ., 28, 962–988). The limiting asymptotic smile in the large‐maturity regime is obtained via a stability analysis of the fixed points of the VIE, and is the same as for the standard Heston model in Forde and Jacquier (2011, Finance Stoch., 15, 755–780). Finally, using Lévy's convergence theorem, we show that the log stock price tends weakly to a nonsymmetric random variable as (i.e., ) whose moment generating function (MGF) is also the solution to the Rough Heston VIE with , and we show that tends weakly to a nonsymmetric random variable as , which leads to a nonflat nonsymmetric asymptotic smile in the Edgeworth regime, where the log‐moneyness as , and we compute this asymptotic smile numerically. We also show that the third moment of the log stock price tends to a finite constant as (in contrast to the Rough Bergomi model discussed in Forde et al. (2020, Preprint) where the skew flattens or blows up) and the process converges on pathspace to a random tempered distribution which has the same law as the hyper‐rough Heston model, discussed in Jusselin and Rosenbaum (2020, Math. Finance, 30, 1309–1336) and Abi Jaber (2019, Ann. Appl. Probab., 29, 3155–3200).     

Effect of personal branding stereotypes on user engagement on short-video platforms

The emergence of short-video platforms offers individuals an opportunity to build personal branding. This study selected two personal brandings on Bilibili.com, Li Ziqi and HuaNong Brothers, to explore the differences in the effect of personal branding stereotypes on user engagement on short-video platforms. We first identified the perception of users based on the Stereotype Content Model, then adopted regression models to construct the relationship between personal branding stereotypes and user engagement. The results show that perceived warmth exerts a more significant influence on user emotional engagement, while perceived competence impacts more on user cognitive and behavioral engagement. Moreover, we find the live comments’ sentiment moderates these effects. This research provided references for individuals and managers to benefit from personal brandings.

The Individual Aspect of Interorganizational Cooperation: Favor-Based Cooperation

ABSTRACT

Purpose

Interorganizational (IO) cooperation has been examined primarily as a role-based concept. This research seeks to extend this concept by examining a distinct mode of IO cooperation: favor-based cooperation. This concept refers to voluntary exchanges of preferential treatments between boundary personnel across organizations that are perceived as going beyond the requirements of their role relationships.
