The Gravity Model and Trade Efficiency: A Stochastic Frontier Analysis of Eastern European Countries' Potential Trade

The opening up process of the eastern European countries is characterised by an increasing degree of trade integration with their Western neighbouring countries. Typically, the degree of East–West trade integration is assessed by comparing actual trade volumes with potential trade volumes projected from the gravity model parameters estimated for a group of countries that best represent normal trade relations. This approach, however, does not compare trade levels against a maximum level of trade feasible for the group of eastern European countries. This paper using a stochastic frontier specification of the gravity model is able to identify the efficiency of trade integration relative to maximum potential levels. The findings, based on a panel data set of bilateral exports from 17 Western European countries to the 10 new member states over the 1994–2007 period, indicate a high degree of East–West trade integration close to two‐thirds of frontier estimates, suggesting a low degree of trade resistances.     

Who is the “Self” that Buys?: An Exploratory Examination of Imaginative Consumption and Explanation of Opinion Leadership

The present research, first, combines literatures on self‐theory, imaginative consumption, and opinion leadership. Second, the research, using self‐theory, explores individual difference variables predictive of imaginative consumption in two studies using different populations. The results reveal fashion product involvement, self‐esteem, fashion knowledge, idea shopping motivation, and probability of a mispurchase influence the degree to which an individual imaginatively consumes fashion products. Third, the research makes a contribution by explaining from where opinion leaders derive their abilities—imaginative consumption. In contributing to scholarly work, the research explains the role of imagination and opinion leadership in both theories of self‐verification and self‐enhancement. Managerial implications include identifying potential opportunities for marketing communications and retail management. The findings are promising and encourage further exploration of the phenomenon of imaginative consumption.     

The Effect of Moral Intensity on Ethical Judgment

Following an extensive review of the moral intensity literature, this article reports the findings of two studies (one between-subjects, the other within-subject) that examined the effect of manipulated and perceived moral intensity on ethical judgment. In the between-subjects study participants judged actions taken in manipulated high moral intensity scenarios to be more unethical than the same actions taken in manipulated low moral intensity scenarios. Findings were mixed for the effect of perceived moral intensity. Both probable magnitude of consequences (a factor consisting of magnitude of consequences, probability of effect, and temporal immediacy) and social consensus had a significant effect; proximity did not. In the within-subject study manipulated moral intensity had a significant effect on ethical judgment, but perceived moral intensity did not. Regression of ethical judgment on age, gender, major, and the three perceived moral intensity factors was significant between-subjects, but not within-subject. Ethical judgment was found to be a more robust predictor of intention than perceived moral intensity using a within-subject design. Joan M.

Harmonization of financial reporting of small and medium-sized enterprises in the Czech Republic

A current problem of the present-day accounting and financial reporting consists in aligning the accounting in small and medium enterprises. In July 2009 the International Financial Reporting Standard for small and medium-sized enterprises was issued, which extended the aligning possibilities also to small and medium enterprises considerably. If the standard is adopted by the national legislation, problems connected with the standard implementation in the national legislation will have to be solved as well as practical issues connected with making financial statements. At present the yields and the problems which can arise in connection with the standard application have to be focused on. A contribution of the standard application will be a better informative ability of financial statements on the international level. At small and medium enterprises this can contribute to better comanunication with banks, with investors, rating application are： parallel reporting according to national agencies etc. The problems connected with the standard regulations, differences between the national legislation and the standard, wide practice at keeping accounts and making financial statements and limited approach of small and medium enterprises to obtaining information and to training of their employees. Another problem can be a tight link between the trading income and the tax base, when small companies prefer rather the tax point of view.     

The VIX,the variance premium and stock market volatility

We decompose the squared VIX index, derived from US S&P500 options prices, into the conditional variance of stock returns and the equity variance premium. We evaluate a plethora of state-of-the-art volatility forecasting models to produce an accurate measure of the conditional variance. We then examine the predictive power of the VIX and its two components for stock market returns, economic activity and financial instability. The variance premium predicts stock returns while the conditional stock market variance predicts economic activity and has a relatively higher predictive power for financial instability than does the variance premium.     

Time to work or time to play: The effect of student employment on homework,sleep, and screen time

We use detailed time-diary information on high school students’ daily activities from the 2003–2008 American Time Use Surveys (ATUS) to investigate the effects of employment on the time a student spends on homework and other major activities. Time-diary data are more detailed and accurate than data derived from responses to “usual activity” survey questions underlying other analyses and capture the immediate effects of working that may well accumulate over time to affect future outcomes. Our results suggest that employment decreases the time that high school students spend on homework, which is human-capital building, on all days, but also decreases screen time on non-school days, which may be considered unproductive time. Employed teens get more than the recommended amount of sleep on school days, and only slightly less on non-school days.     

Production planning and inventories optimization: A backward approach in the convex storage cost case

We study the deterministic optimization problem of a profit-maximizing firm which plans its sales/production schedule. The firm controls both its production and sales rates and knows the revenue associated to a given level of sales, as well as its production and storage costs. The revenue and the production cost are assumed to be respectively concave and convex. In Chazal et al. [Chazal, M., Jouini, E., Tahraoui, R., 2003. Production planning and inventories optimization with a general storage cost function. Nonlinear Analysis 54, 1365–1395], we provide an existence result and derive some necessary conditions of optimality. Here, we further assume that the storage cost is convex. This allows us to relate the optimal planning problem to the study of a backward integro-differential equation, from which we obtain an explicit construction of the optimal plan.
