Determinants of herbicide use in rice production in the Philippines

This study identifies farm‐specific and market factors affecting the adoption of herbicides and the level of herbicide use by rice farmers in the Philippines. This requires the application of a modified version of Heckman's two‐step method to estimate a random‐effects double‐hurdle model for unbalanced panel data. The age of the farmer, household size, and irrigation use are significant determinants of the decision of farmers to adopt herbicides as an alternative to manual weeding, while economic variables such as the price of herbicides, total income, and access to credit determine the level of herbicide use. Determinants of both adoption and level are land ownership, farm area, and the method of crop establishment. These results are potentially relevant when designing policies to reduce excessive herbicide use or to encourage the adoption of alternative weed control methods such as integrated weed management.     

Deregulation of the Australian Wheat Export Market: What Happened to Wheat Prices?

ABSTRACT

This report investigates whether deregulation of the Australian wheat export market induced a structural change in the price data generation process. We analyze the unit root properties of Western Australian wheat price series by testing for the possibility of single and double structural breaks. Daily spot prices for the period of May 20, 2003, to September 14, 2010 are used. We find the wheat price series has a unit root with two structural breaks but neither breaks coincides with the time when the Wheat Export Marketing Act 2008 came into effect on July 1, 2008. The implication of our results is that deregulation was not the main cause of structural breaks in the price series in the sample period.     

‘Nothing gets done and no one knows why’: PCS and workplace control of Lean in HM Revenue and Customs

This article examines the willingness and capacity of public sector unions to mobilise action against changes in the labour process in order to maintain some measure of control at the point of production. Taking as an instance an extended dispute in Her Majesty's Revenue and Customs over the introduction and impact of Lean processes, it marshals evidence gathered from documentary sources, branch representatives and national lay full‐time officers to engage with the notion of a trade union bureaucracy. In taking a union with a left‐wing leadership and a section with 80 per cent membership with an expressed willingness to escalate industrial action, the article tests Hyman's 1979 contention that, rather than a concentration on a bureaucratic caste, a much better explanation for conservatism centres on the nature of social relations within the union that encompass a wider layer of representatives.     

Employee share ownership and performance: golden path or golden handcuffs?

Using matched employer-employee data from the 1998 Workplace Employee Relations Survey, it is suggested that the presence of employee share ownership at a workplace is not significantly associated with employee commitment to the organization. There is evidence of a significant negative relationship between share ownership and workplace turnover, which explains part of the positive share ownership/performance relationship. This calls into question the postulate that share ownership has its main impact upon performance via the closer alignment of employees' and employers' values and interests – the golden path – rather than the lowering of employee turnover – the golden handcuffs.     

Getting too personal: Reactance to highly personalized email solicitations

Research on the effects of personalized messages on consumers’ behavioral responses has yielded mixed findings. We explore how e-mail personalization influences click-through intentions. Our results suggest that consumers experience personalization reactance in response to highly personalized messages when the fit between the offer in the message and consumers’ personal characteristics is not explicitly justified by firms. Consequently, consumers are less willing to respond favorably to the offer. Results of two studies suggest that this effect primarily emerges for consumers who perceive the utility of the service to be relatively low. For those consumers with higher perceived utility, justification of personalization is less important because highly personalized messages are less likely to elicit reactance.

Outlet types and the Canadian Consumer Price Index

Recent phenomenal growth in popularity of large warehouse/discount stores has important implications for price measurement. Consumer substitution to such outlets could produce a bias in consumer price indexes (CPIs), which may be exacerbated by unrepresentative sampling and discount outlets' apparent slower rates of price increases. It is shown that in 1990-96 unit value indexes rose at a lower rate than the corresponding Canadian CPI subaggregate indexes for other household equipment, non-prescribed medicines, and audio equipment, and biases arising from unrepresentative sampling and differential rates of price increases across outlets have resulted in an additional overstatement for these subaggregates.
La croissance dans la popularité des magasins/entrepôts à forts escomptes au cours des der;chnières années a été fort importante et a eu des effets importants sur la mesure des prix. Le comportement du consommateur qui choisit ces magasins pourrait entraîner un biais dans la mesure des indices de prix à la consommation. Un échantillonage non représentatif et le fait que ces magasins semblent avoir des augmentations de prix plus faibles dans le temps peuvent biaiser encore plus les indices. Cette recherche montre que entre 1990 et 1996 les indices de la valeur unitaire ont cru à un taux plus faible que les indices correspondant de prix à la consommation pour des sous-agrégats comme autre ´equipement des ménages, médicaments non-prescrit, et ´equipement audio. Il semble que les biais engendrés par les différentiels de croissance des prix entre magasins et un échantillonnage non représentatif se soient traduits par un biais à la hausse dans ces sous-agrégats     

A Proposed Infrastructural Model for the Establishment of Organizational Ethical Systems

We define ethical system infrastructure as being composed of three major factors – means, motivation, and opportunity. Means are defined as organizational rules, policies, and procedures. Motivation focuses upon the values and the interests being pursued by the position occupant and the organizational value system, while opportunity is discussed in terms of the environment in which the dilemma occurs, proposing that position in the hierarchy presents its own unique set of ethical dilemmas. Ethical breeches are discussed in terms of the interactional processes among means, motivation, and opportunity. Finally, a sequential process is suggested to use the infrastructural components to institutionalize organizational ethics training and subsequent behavior.     

Using tracking technology to improve marketing: insights from a historic town in Tasmania,Australia

ABSTRACT

This study examines the movement patterns of different market segments in an historic town. It combines traditional visitor surveys with a bespoke tourist tracking application. Two analytical stages were undertaken. The first involved analyzing the movements of tourist segments and revealed that “heritage” tourists tended to visit for the shortest lengths of time. The second phase revealed that a visit of between one and two hours seemed to provide the best opportunity to explore the village fully, while shorter and longer stays did not. The insights challenge traditional notions that heritage-oriented tourists should form the target market for historic communities.
