Facebook has become an important platform for a brand–consumer relationship channel. The current study investigates the influence of perceived socialness and its effect on consumers’ attitude toward brands. Participants (N = 404) were recruited in a large southeast university. A 2 (socialness: high vs. low)?×?2 (feedback control: high vs. low)?×?2 (brand image: high vs. low) between-subject design was conducted. The results of this study identified three important findings. First, high (vs. low) socialness elicited higher perceived relationship commitment, brand trust, and more favorable brand attitude. Second, the effect of socialness on brand attitude was moderated by brand image (positive vs. negative). Third, the mediation analysis showed that the effect of socialness (high vs. low) on brand attitude was fully mediated by perceived relationship commitment and brand trust.  相似文献

The Prebisch–Singer hypothesis in economics asserts that over time the relative price of primary goods relative to manufactured goods should experience a downward trend. To test the hypothesis, we must first establish the unit root properties of the relative price term and then regress the stationary series on a trend term. We use the quantile unit root test which allows for both smooth unknown numbers and the form of breaks in the trend function through a Fourier function to show that the relative price of 23 out of 24 primary goods is stationary. However, the Prebisch–Singer hypothesis is supported only in half of the primary commodities.  相似文献

In Appl. Econ. Lett. 18 (2011), 1777–1784, as a natural generalization of some famous production models with two inputs, C.A. Ioan and G. Ioan introduced a new class of production functions with constant return to scale, called sum production function, and proved three theorems of characterization for such production models. In this article, we give new and more simple proofs of these theorems, extending also the results to the case of increased/decreased return to scale. The generalization to the case of an arbitrary number of inputs is also discussed.  相似文献

Using an estimated Beveridge curve, we trace out the vacancy–unemployment ratio in the steady state. This steady-state measure for labour market tightness is embedded in a VAR framework to obtain a benchmark for wage growth reflecting a labour market equilibrium.  相似文献

This study investigates the feminization and defeminization trends in manufacturing employment in thirty countries from 1995 to 2011. Utilizing two separate methods, structural decomposition analysis (SDA) and factor content analysis (FCA), the study identifies the major industries and trade partners behind the structural shifts in trade that have induced changes in employment and thus in the rates of women’s employment. The findings highlight that, as a general trend, defeminization in manufacturing has persisted in the Global North, led by a negative trade impact in low-technology industries. In the Global South, feminization and defeminization trends are not as straightforward. Despite positive changes in women’s share of employment in medium-high- and high-technology industries, negative gender bias effects of trade changes are found particularly in high-technology industries, where occupations are notably gendered.  相似文献

Excessive competitive imbalance holds the potential to render teams and, by extension, leagues inviable. The China Table Tennis Super League has languished in its attempt to catch on as a popular spectator sport in spite of the sport’s popularity as recreational activity. One of the primary reasons for the participation–spectatorship gap cited by officials is competitive imbalance. This research estimates a number of within-season balance measures, including the standard deviation of winning, concentration ratio, and Herfindahl–Hirschman Index. The results show that both the men’s and women’s leagues have been relatively balanced over time. Implications regarding competitive balance and other league policy considerations are explored.  相似文献

The procurement of infrastructure projects via public–private partnerships (PPPs) is rising globally. PPPs are, however, often characterized by lengthy tendering periods, defined as the difference between contract notice and financial close. Tendering periods are important because they account for a significant proportion of overall project delivery time. Slow tendering deters bidders and thus reduces competition for contracts. We source data on 670 PPP projects in the United Kingdom and use a duration analysis model to empirically examine factors that impact tendering period duration. Our results reveal significant sectoral variation with projects in the health and housing sectors taking significantly longer to reach financial close. We also show that, after controlling for other factors, projects with higher capital values and projects that overlap with the timing of general elections are associated with significantly longer tendering periods. We further examine the impact of the competitive dialogue procurement method and find evidence that tendering periods have increased since 2006; the year competitive dialogue was introduced. We do, however, observe a significant reduction in the time between appointment of preferred bidder and financial close post-2006. This suggests that competitive dialogue is effective in reducing the scope for negotiations by preferred bidders holding quasi-monopoly advantages.  相似文献

Although the number of regional trade arrangements (RTAs) among the lowest-income developing countries is surging, the literature on their welfare effects is still scarce, and the few that exist fail to provide conclusive results. Furthermore, these RTAs are dominated by countries with a small share of total exports destined for intraregional trade flows. Our study focuses on the welfare effects of RTAs (pertaining to trade creation and trade diversion) among this group of countries. We use a theoretically justified gravity model to estimate welfare effects, focusing on trade creation and trade diversion and deviating from the norm in related studies, accounting for heterogeneity in third countries. Using ECOWAS as a sample, we estimate welfare effects on 1992–2012 annual bilateral imports for 14 countries from 169 countries. Contrary to conventional expectations in the literature, we find that economic integration among small and relatively low-income countries that have a small share of total trade with each other is welfare-improving for the members as a group, for the majority of the individual member countries, and for some third countries. Accounting for heterogeneity in third countries reveals that an RTA among low-income countries has a particularly robust trade-creation effect.  相似文献

The article proposes a new approach to the Reinhart–Rogoff affair. In contrast to the two explanations of the controversy put forward in existing literature, I argue that Growth in a Time of Debt and its criticism published by Herndon, Ash and Pollin (Does high public debt constantly stifle economic growth? A critique of Reinhart and Rogoff) exemplify the ‘emerging contrary result’ phenomenon (emerging recalcitrant result, ERR). Three arguments support this hypothesis. First, the infamous spreadsheet error did not cause the findings to differ. On the contrary, the results differed mostly due to employing alternative averaging schemes. Second, the cliometric techniques employed by both research teams are justified to a similar degree. Third, the pattern in the cliometric literature focused on the 90%-threshold hypothesis suggests that the Reinhart–Rogoff controversy exemplifies an ERR phenomenon caused by submission/publication bias.  相似文献

In this article, we consider the portfolio selection problem as a Bayesian decision problem. We compare the traditional mean–variance and mean–variance–skewness efficient portfolios. We develop bi-level programming problem to investigate the market’s preference for risk by using observed (market) weights. Numerical experiments are conducted on a portfolio formed by the 30 stocks in the Dow Jones Industrial Average. Numerical results show that the market’s preferences are better explained when skewness is included.  相似文献
