Equipment and non-equipment private investment: a generalized Solow model

The study is an empirical attempt to shed light on which categories of private fixed investment could be relied on to provide the greatest stimulus to economic growth. Panel data, comprising 5-year periodic data over the period 1965–90 pooled across 55 countries, are employed in estimating the model through the fixed-effect technique. In addition to human capital investment ratio, five categories of private fixed investment ratios are tested for. Findings suggest that not all types of investments are conducive to growth.     

An event study of price movements following realized jumps

Price jumps are mostly related to investor reactions to unexpected extreme news. We perform an event study of price movements after jumps to analyse if investors’ reactions are affected by psychological biases. We employ recent non-parametric methods based on intraday returns to separate large price movements that are related to unexpected news from those merely caused by periods of high volatility. In general, we find evidence for irrational pricing, which can be associated with investors’ optimistic behavior in a bull market and the pessimism prevailing in a bear market. Furthermore, our analysis confirms the conjecture that small firms are more subject to speculative trading than large firms.     

Social Technologies,Informal Knowledge Practices,and the Enterprise

This article focuses on the ways in which social technologies facilitate informal knowledge sharing in the workplace. Social technologies include both common technologies such as email, phone, and instant messenger and emerging social networking technologies, often known as social media or Web 2.0, such as blogs, wikis, public social networking sites (i.e., Facebook, Twitter, and LinkedIn), enterprise social networking technologies, etc. We know social technologies support informal interactions over digital systems and influence informal social connections among people within and across organizational boundaries. To understand the role of social technologies in informal knowledge practices, we pursue a field study of knowledge workers in consulting firms to investigate the role of social technologies in their informal knowledge sharing practices. Our theorizing from the data is guided by the conceptual premises of sociomateriality to better understand the ways social technologies are integrated with common knowledge practices. Findings highlight five knowledge practices supported by the use of social technologies. Building from these findings we offer conceptual insights regarding the material performance of different social technologies as an assemblage.     

The Effects of Different Teaching Approaches in Introductory Financial Accounting

Abstract

The purpose of the research is to examine the effect of the two different teaching approaches in the first accounting course on student performance in a subsequent finance course. The study compares 128 accounting and finance students who took introductory financial accounting by either a user approach or a traditional preparer approach to examine their academic performance on a subsequent finance course. The results indicate that there is no significant difference in the finance course grade between students who took the traditional introductory accounting course and students who were taught under the user approach. These findings support the argument that the user approach has no impact on subsequent finance course grade and either method can be used to teach introductory financial accounting. Three factors were found to affect subsequent performance in an introductory finance course: GPA prior to taking the finance course, grades in macroeconomics, and statistics.

Culture, management accounting and managerial performance: Focus Iran

Modern management and control systems may not be equally effective in every country. Budget participation is one of the effective tools in western nations. However, management control tools, in general, and budget participation, in particular, could be ineffective or even dysfunctional in other environments. Hofstede (1980) had suggested that cultural differences among countries are influencing factors. In this study, we investigate the impact of culture, budgetary participation, and management accounting systems on managerial performance in Iran. Three-way analyses of variance are used separately for each of the four cultural Hofstede dimensions. We find convincing evidence that the application of management tools and techniques developed in western countries for effective management performance is not as useful in the Iranian context.     

Is an Exhaustible Resource Economy Sustainable?

The paper focuses on two alternative concepts of sustainability dominating the literature: (i) maximum permanently maintainable consumption level (Fisherian income) and (ii) the amount of consumption that leaves total value of wealth intact (Hicksian income). In the context of a pure exhaustible resource economy, the author derives an explicit relationship between the two sustainability criteria and shows that while such an economy is not sustainable in the former sense, it is in the latter sense provided social preferences are represented by a logarithmic utility function. The implications of the two concepts for greening of national income are derived. Finally, the paper shows the range of values of the parameters of the model for which the utilitarian optimal path can be close to paths satisfying the alternative sustainability criteria, suggesting that such outcomes are less likely for very poor resource‐dependent countries than for the rich ones.     

A call for weather condition revaluation in mega-events management

This article provides a new insight into knowledge-based management of mega-events by highlighting the significance of weather at destination selection and scheduling events as an adaptive strategy toward climate change. Concerning the environmental and socio-economic costs of weather ignorance in event management, which may result in cancelation and change of the event time, it is recommended that planners perform a preliminary study prior to publicizing an event plan. Doing so, the organizer and visitors can benefit from optimal weather at the destination, as this study advises the decision-makers of the Tokyo 2020 Olympic and Paralympic Games to reschedule the dates of this international event.
