Bibliometrics of social media research: A co-citation and co-word analysis

This study combined two bibliometric analysis methods to provide a systematic and holistic review of social media-related academic literature. A total of 406 publications related to social media between 2007 and 2016 were identified from 16 business and hospitality/tourism journals. Co-citation analysis identified Word-of-Mouth as the major theoretical foundation of social media research in business, while the hospitality/tourism field presented a diverse theoretical foundation. The study then employed co-word analysis to identify the evolution of research themes over time in both fields. The comparison of social media research between the two fields highlighted four similarities, including the growth of research over time, the term “social media” gaining popularity, the new trend of social networking sites, and managerial applications as research focus. Finally, the study called for a future research agenda on social media research in the hospitality/tourism field.

Measuring Production and Irrigation Efficiencies of Rice Farms: Evidence from the Punjab Province,Pakistan

We employ a non‐parametric approach, data envelopment analysis, to estimate the technical and irrigation efficiency of rice farms in the Punjab Province of Pakistan. We use a cross‐sectional dataset of 80 rice growers, including 45 tube‐well owners and 35 water buyers. Mean technical efficiency scores show that tube‐well owners and water buyers are operating at fairly high efficiency levels, indicating that access to technology is not a major constraint. However, irrigation inefficiency is pronounced, with water buyers being more inefficient than tube‐well owners. A bootstrap truncated regression is used to investigate the determinants of technical and irrigation efficiency. We suggest that groundwater management policies should be designed to address efficiency enhancing factors such as knowledge of crop water consumption requirement, better credit opportunities, outreach extension services and training programs.     

When was the U.S. housing downturn predictable? A comparison of univariate forecasting methods

This paper uses three classes of univariate time series techniques (ARIMA type models, switching regression models, and state-space/structural time series models) to forecast, on an ex post basis, the downturn in U.S. housing prices starting around 2006. The performance of the techniques is compared within each class and across classes by out-of-sample forecasts for a number of different forecast points prior to and during the downturn. Most forecasting models are able to predict a downturn in future home prices by mid 2006. Some state-space models can predict an impending downturn as early as June 2005. State-space/structural time series models tend to produce the most accurate forecasts, although they are not necessarily the models with the best in-sample fit.     

Optimal investment strategies in an international economy with stochastic interest rates

We investigate how investors should optimally choose to invest in a dynamically complete international market. We find closed-form solutions for the optimal investment strategy and for the wealth loss an investor suffers from not investing internationally. Theoretically, we show that the gain from international investment is due to the speculative investment only, and why it is important for an investor from a large economy to invest in a small economy. In a numerical example we compare the wealth losses investors from Denmark and the U.S. suffer due to home bias.     

Usage of the concept of culture and heritage in the United Arab Emirates – an analysis of Sharjah heritage area

Under the forces of an oil-based economy and the fast paced change, nationals in the United Arab Emirates (UAE) and other Gulf states are becoming very keen to preserve, represent and invent a distinct ‘national’ culture and heritage. Fears of ‘loss’ of identity and concerns about ‘global’ culture are powerful social forces. Heritage revival has become a significant social, cultural and political process in the UAE, the most public sign of this being the development of ‘Heritage Villages’. This analysis explores themes of heritage revival and the preservation, representation and construction of culture in the UAE with specific analysis of the Sharjah Heritage Area (SHA). It will be shown that heritage revival in the UAE is both a symbolic and practical negation of globalization. Heritage revival is also increasingly an affirmation of the fast paced development of international business and tourism in the Emirates which is the focus of economic diversification. SHA will first be examined as a museum exhibitionary complex combining museum, festival and shopping. The representation, performance, negotiation and interplay of local/global and old/new culture at the SHA will be outlined in the context of transnationalism and the oil-propelled modernization.     

Minimum Wage Compliance and the Labor Demand Curve

Contrary to the traditional analysis of the employment effects of the minimum wage setting, the author shows that if compliance is contingent upon enforcement, complying with the minimum wage law involves a leftward shift of the labor demand curve rather than an upward movement along the curve. Furthermore, the labor demand curve will shift leftward with enforcement even if enforcement is insufficient to ensure compliance, becoming vertical when the options of compliance and noncompliance are equally attractive. Hence, it is not paying the statutory minimum wage that brings about a reduction in employment down to the full-compliance level but enforcement that, if sufficiently high, induces that same reduction in employment, even if the employer is still noncomplying with the minimum wage law.     

The European Union Endorsement Process for International Financial Reporting Standards: A Telos-Based Analysis

The paper discusses the process for the endorsement of an IFRS in the European Union with regard to its compliance with teleological principles and with regard to the true and fair view. It begins with an exposition of the teleological principle under Roman law and its relationship to the true and fair view override, as known in the UK and in the EU. We then discuss firstly the telos-based criteria against which a new Standard is appraised during the endorsement process, and secondly the application of the true and fair view principle to the issue of which criteria an EU-endorsed IFRS should be appraised against as regards its application, using IFRS 3 as a specific illustration. The teleological principle is a crucial element in our conclusions. We show that this principle can be used, and in the EU is being used, to bypass democratic processes. The issues raised by this paper concern the operation of regulations designed to be, at least theoretically, context-neutral, within a specific legal and operational framework, that is, the European Union. But similar issues are likely to require consideration in other geographical areas, outside the European context.
