How resilient is La Réunion in terms of international tourism attractiveness: an assessment from unit root tests with structural breaks from 1981-2015

Even if local policymakers increasingly claim that tourism is one of the key factors of future economic development for the French small island La Réunion, international tourist arrivals are observed to be locked in a stagnation phase since the beginning of the 2000s. Starting from this stylized fact, this article aims to study if this phenomenon results from major external events hurting this economy regularly. Next, by using univariate unit root procedures with structural breaks, we test for evidence of permanent or transitory effects of external shocks on international tourist inflows (total, by source markets, and by category) over the period 1981–2015. Finally, the empirical analysis allows us to reject the null of a unit root. Then, stagnation of tourism arrivals to La Réunion is not due to exogenous shocks but probably results from endogenous impediments within the domestic tourism industry and unsuitable public policies.     

Fame and the fortune of academic economists: How the market rewards influential research in economics

We analyze the pay and position of 1009 faculty members who teach in doctoral‐granting economics departments at 53 large public universities in the United States. Using the Web of Science, we have identified the journal articles published by these scholars and the number of times each of these articles has been subsequently cited in published research articles. We find that research influence, as measured by various measures of total citations, is a remarkably strong predictor of the salary and the prestige of the department in which professors are employed. We also examine the effect of coauthorship. Surprisingly, we find no salary penalty for sharing authorship; however, in terms of prestige of employing department, coauthorship is fully discounted.     

Corporate social responsibility in emerging economies: Investigating firm behavior in the Indian context

Scholars have questioned the appropriateness of using a western‐centric framework to investigate corporate social responsibility (CSR) in emerging economies. This study assesses the appropriateness of using such a framework in one emerging economy—India. More specifically, the drivers of CSR and their impact on firm‐level CSR activity in the Indian context are investigated and compared with those in developed economies. Content analysis of 369 CSR policy statements of publicly traded Indian firms revealed the factors that drive CSR activities of Indian firms are similar to those found in developed economies. However, the ways firms respond to the drivers of CSR are surprisingly different in the Indian context, and these differences can be traced to attributes of the Indian socio‐cultural context. Implications and recommendations for future research conducted in India, and in other emerging economies, are offered.     

Reliable Inference in Categorical Regression Analysis for Non‐randomly Coarsened Observations

In most surveys, one is confronted with missing or, more generally, coarse data. Traditional methods dealing with these data require strong, untestable and often doubtful assumptions, for example, coarsening at random. But due to the resulting, potentially severe bias, there is a growing interest in approaches that only include tenable knowledge about the coarsening process, leading to imprecise but reliable results. In this spirit, we study regression analysis with a coarse categorical‐dependent variable and precisely observed categorical covariates. Our (profile) likelihood‐based approach can incorporate weak knowledge about the coarsening process and thus offers a synthesis of traditional methods and cautious strategies refraining from any coarsening assumptions. This also allows a discussion of the uncertainty about the coarsening process, besides sampling uncertainty and model uncertainty. Our procedure is illustrated with data of the panel study ‘Labour market and social security' conducted by the Institute for Employment Research, whose questionnaire design produces coarse data.     

Information Exchange and Transnational Environmental Problems

This paper analyzes information exchange in a model of transnational pollution control in which countries use private information in independently determining their domestic environmental policies. We show that countries may not always have an incentive to exchange their private information. However, for a sufficiently high degree of predictability of domestic environmental policy processes, the expected welfare from sharing information is greater than the expected welfare from keeping it private. The minimum degree of policy predictability for which information sharing occurs increases with the level of environmental risk. Intuitively, information exchange can help mitigate the perception of global uncertainty (both political and scientific) that surrounds transnational environmental problems and potentially improve welfare if policymaking processes are sufficiently aligned with evidence-based approaches (predictable).     

On the implied market price of risk under the stochastic numéraire

This papers addresses the stock option pricing problem in a continuous time market model where there are two stochastic tradable assets, and one of them is selected as a numéraire. An equivalent martingale measure is not unique for this market, and there are non-replicable claims. Some rational choices of the equivalent martingale measures are suggested and discussed, including implied measures calculated from bond prices constructed as a risk-free investment with deterministic payoff at the terminal time. This leads to possibility to infer a implied market price of risk process from observed historical bond prices.     

Policy implications of research on non-GAAP reporting

Over the past two decades, the regulatory landscape for non-GAAP reporting has evolved significantly. Despite a temporary decline in the frequency of non-GAAP reporting following Regulation G, the incidence of non-GAAP disclosure has continued to increase steadily, leading to a current all-time high in reporting activity. This proliferation of non-GAAP disclosure has captured the attention of standard setters and regulators in recent years. This paper provides an academic perspective on policy implications for both regulation and standard setting. We contend that current Compliance and Disclosure Interpretations (C&DIs) of the SEC staff may perhaps have gone too far in restricting certain types of non-GAAP disclosures. As a result, we advocate a slight relaxation of the current enforcement of Regulation G. We agree with FASB proposals for greater disaggregation in the income statement to allow for more transparency in non-GAAP reporting. Finally, we believe the PCAOB should consider requiring auditors to take a more direct role with respect to non-GAAP disclosures.     

YouTubers’ networking activities during the 2016 South Korea earthquake

While YouTube has become an important social networking platform for risk and crisis communications, research into its role and use during environmental disasters has not been conducted. The present study investigates how Korean YouTubers reacted during the 2016 Gyeongju earthquakes. Two kinds of data were collected from the most popular YouTube clips on the earthquake (from AfreecaTV and YonHap news): the most frequently used words in the replies to the comments and the networked forums among YouTubers. Findings suggest that YouTube has become a channel for quickly increasing public awareness of crises and for promoting safety strategies. InDegree Centralization is higher in professional videos. Hierarchy measure’s value is one, which means the reply-to network is not two-way. There is sparse close-knittedness in amateur videos. Community clusters emerge in amateur videos over time. The results also reveal that YouTubers on AfreecaTV are more likely to express emotional opinions than their counterparts on YonHap news are.     

Discovering India's three levels of luxury consumption: An exploratory research to find a conceptual framework

Luxury marketing research has moved from functional product attributes to a ‘democratized’ view in emerging economies. This seems to be based on the development of interactive and digital communications. Luxury research studies have historically focused on the brand's and marketer's perspectives. Thus, little attention has been given to the consumer's view of what we consider to be the individual drivers, i.e., the ‘inner and outer self’ and how that impacts luxury consumption. This paper presents a framework of luxury and self, using concepts such as interdependent or outer, independent or inner, and a new concept of ‘digital self’. These appear as three levels of luxury consumption, i.e., conspicuous, individual, and interactive. The interdependent self is influenced by the external motives and leads to conspicuous luxury behavior. Individual self is affected by internal motives and thus influences individual luxury consumption. Digital self affects the networks of motive and relationships and thereby impacts interactive luxury consumption and behavior.
