AbstractLogistic regressions identified determinants of red and white wine purchases in formal and casual restaurants, using a detailed dataset of over 26,000 consumer-level food away-from-home purchases in two Canadian provinces during 2000–2005. Meal context regressors, and prior behavior associated mainly with unobserved heterogeneity, contributed most of the explanatory power, with observable demographic regressors playing a modest role. The main strategic recommendation is thus to focus wine marketing resources on the restaurant environment, with less emphasis on targeting specific audiences. (JEL Classification: C25, D12)

Objective - The role of knowledge management and competencies related to marketing skills are essential for Indian and Maldivian businesses, due to the emerging economy and globalization. This study therefore aims to identify the impact of marketing competencies on organizational performance in automobile sales centers, by reviewing the relationship between marketing competencies and firm performance, to support interest and investments in such a concept. Methodology/Technique - 424 respondents (327 Indian samples and 97 Maldivian samples) were randomly selected for the research, with a 71% response rate. The first section of the questionnaire consists of questions related to marketing competencies (32 items) and the second section contains items related to organizational performance (10 items), and the last part includes questions about the respondents' demographical differences. After the data collection, construct validity and reliability statistic tests were conducted to check the validity and reliability of the instrument using IBM SPSS AMOS 23. Findings - The structural equation modelling results for the Indian and the Maldivian samples reveal that marketing competencies have a significant and positive affect on organizational performance. Novelty - This study may be useful for policymakers and top-level managers in the automobile sector; this study provides empirical insights into how the performance of the firm is affected by marketing competencies. Type of Paper: Empirical. Keywords: Marketing Competency; Marketing Resources and Capabilities; Automobile Sales Centers; India; Maldives. JEL Classification: M30. M31. M37. M39

This study aims provide understanding of the local-level spatiotemporal evolution of COVID-19 spread across capital regions of South Korea during the second and third waves of the pandemic (August 2020~June 2021). To explain transmission, we rely upon the local safety level indices along with latent influences from the spatial alignment of municipalities and their serial (temporal) correlation. Utilizing a flexible hierarchical Bayesian model as an analytic operational framework, we exploit the modified BYM (BYM2) model with the Penalized Complexity (PC) priors to account for latent effects (unobserved heterogeneity). The outcome reveals that a municipality with higher population density is likely to have an elevated infection risk, whereas one with good preparedness for infectious disease tends to have a reduction in risk. Furthermore, we identify that including spatial and temporal correlations into the modeling framework significantly improves the performance and explanatory power, justifying our adoption of latent effects. Based on these findings, we present the dynamic evolution of COVID-19 across the Seoul Capital Area (SCA), which helps us verify unique patterns of disease spread as well as regions of elevated risk for further policy intervention and for supporting informed decision making for responding to infectious diseases.

Effective agricultural policymaking requires the accurate estimation of the production technology and efficiency of farms. However, several methodological issues should be considered when modelling production and estimating technical efficiency. In this paper, we focus on two of these—technological heterogeneity and theoretical consistency—as implied in microeconomic theory. Heterogeneity in the efficiency literature is often evaluated using a variable intercept model. However, in farm production, it is likely that heterogeneity also affects the marginal productivity of production factors. Some earlier papers investigated the effect of unobserved heterogeneity on technical efficiency using latent class models, but the application of random parameter models is limited. One of our main contributions in this paper is that we apply a modified version of a random parameter model to investigate the effect of unobserved heterogeneity on production factors and efficiency. The second aim was to impose regularity conditions into the model through introducing linear and non-linear constraints and thereby investigate their significance. Third, we examined the relationship between unobserved heterogeneity and the natural and economic conditions of farms. Our findings show that heterogeneity has a greater effect on variation in output than technical efficiency; furthermore, the violation of theoretical consistency significantly influences the results. These findings also reveal that the explanatory power of regional natural and economic conditions is significant but not sufficient on the variance of estimated unobserved heterogeneity.

Abstract Emerging evidence from neuroscience and clinical research suggests a novel hypothesis about tobacco use: consumers may choose to smoke, in part, as a "self-medicating" response to the presence of economic insecurity. To test this hypothesis, we examine the effect of economic insecurity (roughly, the risk of catastrophic income loss) on the smoking behavior of a sample of male working-age smokers from the 1979 National Longitudinal Survey of Youth (NLSY79). Using instrumental variables to control for unobserved heterogeneity, we find that economic insecurity has a large and statistically significant positive effect on the decision to continue or resume smoking. Our results indicate, for example, that a 1 percent increase in the probability of becoming unemployed causes an individual to be 2.4 percent more likely to continue smoking. We find that the explanatory power of economic insecurity in predicting tobacco use is comparable to (but distinct from) household income, a more commonly used metric.

For determining the expected return, and asset pricing, CAPM (Capital asset pricing model) is being used dominantly grounded on only the market (systematic) risk-factor though several anomalies have been revealed in this model. Fama and French (1993) have addressed those anomalies and developed the Three-factor model by combining size and value factors besides market factors. Over time, Carhart (1997) has further developed a model addressing momentum factor besides the three factors of Fama and French (1993) which is known as the Carhart four-factor model. Though several kinds of research have been conducted on the CAPM and three-factor model, little works have been accompanied by the Carhart four-factor model in an evolving market like Bangladesh. The goal of this work is to examine the validity of the Carhart four-factor model and examine the loftier explanatory power in Dhaka Stock Exchange (DSE). From the regression analysis of the Carhart model, we have found that market, size, value, and momentum explain the excess stock return. This study indicates that the Carhart model has the lowest GRS F-statistic, highest adjusted R-squared, and lowest Sharpe ratio in contrast to the CAPM and three-factor model which indicates the superior explanatory power and statistical validity of the Carhart model.

Whereas considerable effort has been expended in prior research in discussing the appropriateness of alternative measures of income in expenditure studies, this paper looks in depth at the impact of incorporating a broad range of demographic variables in the expenditure analysis. Food expenditures away from home are used to analyze the additional gains in explanatory power and the impact of demographic variables on income elasticities. Considerable divergence of results is found under the alternative measures of income.

Abstract The presumably most important function of a corporation is the establishment and management of connections to customers, suppliers, investors, debtors and competitors. All these connections may produce profits or bear risks. Hence, the isolated inspection of a corporation (or also a sovereign) may be insufficient. Instead, the economic environment of a corporation and its connections should be included in its valuation. Usually, this is done via manual and hardly standardized processes with their associated large efforts. This article presents a new method to analyze business news and to build up a network of corporations based on business news. To this end, we search in news articles from Reuters and Bloomberg for corporation names or synonyms and assume a connection exists between two corporations if the corporations are mentioned together frequently. Based on these connections, we (1) build up a network for the S&P500 companies, (2) identify groups therein to validate the approach manually and (3) test, whether corporations with many connections and a particularly favorable position in the network receive better rating grades compared to corporations with fewer connections and an average network position. The latter is equivalent to the question of whether a corporation’s connections are a driver of the firm value. Moreover, we use the business news to measure a corporation’s publicity and sentiment, and relate these to the corporation’s rating as well. Our empirical results indicate that the network properties, the sentiment and the media attention are contained in respectively affect the rating grade. Hence, the incorporation of news in the firm valuation – as it is done by many financial institutions – is reasonable. The factors mentioned above increase the explanatory power of our regression model significantly. Since many corporations have sufficient news coverage for our approach but are not rated from a rating agency, and hence must be rated with internal models, our approach may support manual processes in financial institutions and reduce efforts and costs. Zusammenfassung Eine der zentralen aber oft unterschätzten Aufgaben von Unternehmen ist der Aufbau und die Pflege von Beziehungen zu Kunden, Lieferanten, Gläubigern, Investoren oder auch Konkurrenten, aus denen Profite und gegebenenfalls auch Risiken resultieren. Daher ist die isolierte Betrachtung eines Unternehmens (oder auch eines Staates) für dessen Bewertung oft nicht ausreichend. Stattdessen sollten das wirtschaftliche Umfeld eines Unternehmens und die Verbindungen eines Unternehmens direkt in dessen Bewertung einfließen. Deren zumeist qualitative, wenig standardisierte Analyse verursacht bei Kreditinstituten meist hohe Aufwände. Dieser Artikel beschreibt die Analyse von Unternehmensnachrichten und die Herleitung von Netzwerken dieser Unternehmen aus deren Unternehmensnachrichten. Hierzu suchen wir in Nachrichten von Reuters und Bloomberg nach Unternehmensnennungen und gehen von einer Verbindung zwischen zwei Unternehmen aus, wenn diese häufig in denselben Nachrichten genannt werden. Aufgrund dieser Verbindungen (1) erzeugen wir ein Netzwerk für die Unternehmen im S&P500, (2) identifizieren nicht-triviale Unternehmensgruppen und (3) testen, ob gut vernetzte Unternehmen eine bessere Bonitätsnote von den Ratingagenturen erhalten als weniger gut vernetzte Unternehmen. Letzteres ist gleichbedeutend mit der Fragestellung, ob eine gute, zentrale Positionierung eines Unternehmens in einem Netzwerk einen messbaren Mehrwert für das Unternehmen schafft, der sich im Rating niederschlägt. Darüber hinaus nutzen wir die Unternehmensnachrichten auch dazu um Kennzahlen abzuleiten, die die Aufmerksamkeit und die Stimmung der Nachrichtenlage unternehmensspezifisch messen und somit das wirtschaftliche Umfeld eines Unternehmens quantifizieren. Bezüglich dieser Kennzahlen überprüfen wir ebenfalls, ob sie einen messbaren Einfluss auf die Ratingnoten haben. Unsere Ergebnisse legen nah, dass sich sowohl Netzwerkeigenschaften als auch die Nachrichtenlage in der Bonitätseinschätzung niederschlagen. Diese Kennzahlen steigern den Erklärungsgrad unseres Shadow-Rating Modells erheblich. Da viele Unternehmen eine für unseren Ansatz hinreichende Nachrichtenabdeckung besitzen, aber kein Agenturrating, kann unser Ansatz besonders bei der Bewertung von Adressrisiken mit internen Modellen manuelle Prozesse ablösen und zu Effizienzsteigerungen führen.

The use of salience as a tool to determine which stakeholders matter may lead to the marginalization of some stakeholder groups. As a normative theory, salience is problematic because it uproots stakeholder theory from its moral foundations. As a descriptive theory, its prevalence has found mixed support in literature. In order to overcome these limitations, scholars have recommended grounding stakeholder theory in ethics of care. These recommendations have largely been normative but still lack empirical support. We present the case of Escuela Social Ana Bella to show that, particularly when dealing with marginalized stakeholders, stakeholder theory rooted in ethics of care has considerable explanatory power. We find that firms can engage with fringe stakeholders when the decisions of managers are informed by emotions. We also find that this engagement can have the power to transform the beneficiary stakeholder group to an extent where they may become, paradoxically, salient stakeholders for the firm.

This paper critically examines Robin Hahnel’s 2017 book Radical Political Economy: Sraffa versus Marx and especially compares the relative explanatory power of Marx’s theory and Sraffa’s theory. Hahnel’s book argues that Sraffa’s theory is superior to Marx’s theory with respect to the following six subjects: prices, profit, technological change, crises, the environment, and moral critique (each one considered in a separate chapter). This paper challenges Hahnel’s arguments on all six subjects and argues that Marx’s theory has greater explanatory power than Sraffa’s theory and continues to be the best critical theory of capitalism.

Abstract This article presents a history of the origins and development of the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), from the publication of an article titled “A Guide to the Evaluation of Permanent Impairment of the Extremities and Back” (1958) until a compendium of thirteen guides was published in book form in 1971. The most recent, sixth edition, appeared in 2008. Over time, the AMA Guides has been widely used by US states for workers’ compensation and also by the Federal Employees Compensation Act, the Longshore and Harbor Workers’ Compensation Act, as well as by Canadian provinces and other jurisdictions around the world. In the United States, almost twenty states have developed some form of their own impairment rating system, but some have a narrow range and scope and advise evaluators to consult the AMA Guides for a final determination of permanent disability. An evaluator's impairment evaluation report should clearly document the rater's review of prior medical and treatment records, clinical evaluation, analysis of the findings, and a discussion of how the final impairment rating was calculated. The resulting report is the rating physician's expert testimony to help adjudicate the claim. A table shows the edition of the AMA Guides used in each state and the enabling statute/code, with comments.
