Emerging managerial competencies of professionals in the Tanzanian construction industry

The managerial competencies required by professionals in the construction industry in Tanzania to operate effectively in a business environment which is changing as a result of a transition from a socialist to a free-enterprise economy, economic liberalization, globalization and regionalization are explored through a qualitative study. The study reveals that local Tanzanian construction firms are finding it difficult to compete with foreign companies for projects. This is mainly because Tanzanian professionals lack the competencies required to compete and manage projects in a liberalized market economy.

The study thus highlights the need for Tanzanian construction professionals to acquire a better grasp of both occupational and organizational competencies. In this respect, it is suggested that they need post-experience training in order to acquire the competencies required to function successfully in a commercial environment.     

Forecasting Consumption: the Role of Consumer Confidence in Real Time with many Predictors

We study the role of consumer confidence in forecasting real personal consumption expenditure, and contribute to the extant literature in three substantive ways. First, we re‐examine existing empirical models of consumption and consumer confidence, not only at the quarterly frequency, but using monthly data as well. Second, we employ real‐time data in addition to commonly used revised vintages. Third, we investigate the role of consumer confidence in a rich information context. We produce forecasts of consumption expenditures with and without consumer confidence measures using a dynamic factor model and a large, real‐time, jagged‐edge dataset. In a robust way, we establish the important role of confidence surveys in improving the accuracy of consumption forecasts, manifesting primarily through the services component. During the recession of 2007–2009, sentiment is found to have a more pervasive effect on all components of aggregate consumption: durables, non‐durables and services.

Visitor perceptions of crime-safety and attitudes towards risk: The case of Table Mountain National Park,Cape Town

This paper investigates tourist perceptions of crime-safety and attitudes towards risk whilst visiting Table Mountain National Park (TMNP) in Cape Town in June and July 2008. The study examined survey data of 303 domestic and international tourists during their visit to TMNP. A linear regression analysis revealed that although visitors had concerns about their personal safety they are still likely to return to TMNP and recommend it to other people. In addition, visitor attitudes towards risk did not influence perceptions of crime-safety and its effect on their intentions to revisit or recommend TMNP. The results also show that respondent's individual characteristics such as age, nationality, and purpose of visit influenced their perceptions of crime-safety. Perceptions that TMNP is unsafe tended to increase with respondent's age. Respondents on holiday were more likely to perceive TMNP as safer than those on business or visiting friends and relatives. The study's findings add to the literature by offering more insight on tourist perceptions of crime-safety and attitudes towards risk and their impact on tourist behaviour. Various tourist-crime prevention measures to enhance visitor safety at national parks are also recommended to the tourism industry and law enforcement agencies.     

Consumer food safety perceptions and self‐reported practices in Greece

A substantial proportion of foodborne illness is associated with food prepared in households. The primary understanding of how foods are handled in private homes comes mostly from questionnaire based studies and direct observation. The aim of this survey was to examine consumers' perceptions and knowledge of safe food handling practices in Greece. More specifically, their attitudes, opinions and self‐reported practices were studied. Data were collected from a total of 399 consumers living in Greece by the use of a self‐administered on‐line survey. The questionnaire consisted of four positive and five negative statements according to the 5‐point Likert scale, which grouped into three constructions using principal component analysis in order to investigate food safety perceptions of consumers. Furthermore, the survey included 11 demographic questions, two close‐ended questions (type yes/no) and four questions that are related to self‐reported food‐handling practices. The results showed that the most commonly known bacterium causing food‐related illness according to respondents' knowledge is Salmonella (99.7%), followed by Escherichia coli (73.9%) and Listeria (58.4%). The overall consumers' score concerning food safety was 32.8 ± 5.37 (full score was 45). No significant differences to the mean score of food safety knowledge were found according to gender, age or the incidence of foodborne illness over the past 12 months. Knowledge and awareness of safe food handling practices was enhanced at higher education levels, while homemakers were found to have deficiencies at this level. Information obtained from consumers can be used to shape educational programs and determine where food safety educational efforts would be most effective and the needed content of the messages.     

REAL OPTIONS WITH COMPETITION AND REGIME SWITCHING

In this paper, we examine irreversible investment decisions in duopoly games with a variable economic climate. Integrating timing flexibility, competition, and changes in the economic environment in the form of a cash flow process with regime switching, the problem is formulated as a stopping‐time game under Stackelberg leader‐follower competition, in which both players determine their respective optimal market entry time. By extending the variational inequality approach, we solve for the free boundaries and obtain optimal investment strategies for each player. Despite the lack of regularity in the leader's obstacle and the cash flow regime uncertainty, the regime‐dependent optimal policies for both the leader and the follower are obtained. In addition, we perform comprehensive numerical experiments to demonstrate the properties of solutions and to gain insights into the implications of regime switching.     

International Comparisons of Australia's Infrastructure Performance

International benchmarking has played a key role in the reform of Australia's infrastructure industries by promoting indirect or yardstick competition, in highlighting the need for further reform and building a consensus for implementing necessary changes. The international benchmarking of infrastructure performance by the Bureau of Industry Economics (BIE) between 1991 and 1996 did much to focus attention on the need for change. The BIE examined the performance of eight infrastructure industries relative to international best practice: electricity, rail freight, telecommunications, the waterfront, road freight, coastal shipping, aviation and gas supply. Performance comparisons concentrated on indicators of price, service quality, labour productivity and capital productivity. This paper reviews and summarises the performance comparisons the BIE undertook over the last three years of its infrastructure benchmarking program. The BIE international benchmarking program provides a useful role model for other countries wanting to seriously pursue reform of their infrastructure industries.     

The Market Performance of Socially Responsible Investment during Periods of the Economic Cycle – Illustrated Using the Case of FTSE

The debate about socially responsible investment (SRI) portfolio performance compared with its non‐SRI counterparts remains inconclusive. This paper contributes to the debate by adding a new approach, examining the issue of a full economic circle through economic boom, recession and recovery. We compare stock performance of two value‐weighted investment portfolios: FTSE4Good (SRI portfolios) and FTSE 350 (conventional portfolios) from 2004 to 2011 including 2007 to 2009 financial crash. The results indicate the SRI portfolio performed better and recovered its value quicker in post‐crisis than the non‐SRI portfolio, indicating that SRI portfolios are more resilient to economic turmoil and market shocks.

Regulating,joint bargaining,and the demise of precedent

Recent decades have seen a fundamental shift in the nature of economic regulation in the United States. Unauthorized by congress, and largely unnoted in legal and academic circles, regulatory agencies such as the Federal Communications Commission have changed the regulatory process by linking otherwise unrelated regulatory issues. Examples include tying merger approval to firm commitments to engage in conceptually unrelated build‐outs and other projects of political importance. This linking of issues has several effects, the most prominent being (a) tying regulatory issues changes the outcomes obtained, plausibly in predictable ways; (b) tying in some circumstances allows regulators to extend their authority to issues for which they have little or no legal authority; and (c) tied regulatory bargaining fails to produce valid legal precedent for firm decision making. We provide an analysis of these conclusions by examining the increasing use of consent decrees, voluntary merger commitments, and merger conditions by the Federal Communications Commission, referencing our discussion with a simple model of joint bargaining applicable to regulatory practice.
