Selected AbstractsThe North American Industry Classification System and Its Implications for Accounting Research,CONTEMPORARY ACCOUNTING RESEARCH, Issue 4 2003Jayanthi Krishnan Abstract Industry classification is an important component of the methodological infrastructure of accounting research. Researchers have generally used the Standard Industrial Classification (SIC) system for assigning firms to industries. In 1999, the major statistical agencies of Canada, Mexico, and the United States began implementing the North American Industry Classification System (NAICS). The new scheme changes industry classification by introducing production as the basis for grouping firms, creating 358 new industries, extensively rearranging SIC categories, and establishing uniformity across all NAFTA nations. We examine the implications of the change for accounting research. We first assess NAICS's effectiveness in forming industry groups. Following Guenther and Rosman 1994, we use financial ratio variances to measure intra-industry homogeneity and find that NAICS offers some improvement over the SIC system in defining manufacturing, transportation, and service industries. We also evaluate whether NAICS might have an impact on empirical research by reproducing part of Lang and Lundholm's 1996 study of information-transfer and industry effects. Using SIC delineations, they focus on whether industry conditions or the level of competition is the main source of uncertainty resolved by earnings announcements. Across all levels of aggregation, we find inferences are similar using either SIC or NAICS. How-ever, we also observe that the regression coefficients in Lang and Lundholm's model show smaller intra-industry dispersion for NAICS, relative to SIC, definitions. Overall, the results suggest that NAICS definitions lead to more cohesive industries. Because of this, researchers may encounter some differences in using NAICS-industry definitions, rather than SIC, but these will depend on research design and industry composition of the sample.

Babor From a public health perspective, alcohol advertising should not be directed at vulnerable groups, nor should it portray excessive drinking or other objectionable content such as illegal activity. To promote the responsible advertising of alcoholic beverages, alcohol industry groups have developed self-regulation guidelines that describe which types of content (and exposure markets) are unacceptable. In 2006 the US Beer Institute revised the content guidelines of the 1997 Beer Code. This study was designed to determine whether these changes made the revised Code more or less likely for expert judges to report guideline violations, and for alcohol advertisements to include otherwise inappropriate content from a public health perspective. Six alcohol advertisements known or suspected to have multiple content violations were rated by 139 experts selected on the basis of their expertise in public health, mental health, alcohol research and marketing. The ads were rated on two occasions with feedback about other viewers' ratings provided at the second rating. The data were collected by means of a computer-based rating program that used multiple items to evaluate the eight major content guidelines of the US Beer Code. The ratings were scored according to both the 1997 and the 2006 versions of the Beer Code. According to the 1997 criteria, raters identified an average of 26 guideline violations across the six ads; the number of violations was reduced to 18 when the 2006 criteria were applied. The difference was statistically significant and was primarily attributable to changes in guidelines dealing with the portrayal of illegal activity, humorous situations and the act of drinking. By removing or revising commonly violated guidelines, the 2006 Beer Code revision permits portrayal of previously objectionable ad content and increases the likelihood that risky drinking behaviours will be portrayed in US beer advertisements.

[source] Has the EU's Single Market Programme Fostered Competition?OXFORD BULLETIN OF ECONOMICS & STATISTICS, Issue 4 2007Testing for a Decrease in Mark-up Ratios in EU Industries Abstract We use a panel approach, covering 10 EU Member States over the period 1981,99, for each of three major industry groups (manufacturing, construction and services) and 18 more detailed industries to test whether the EU's Single Market Programme has led to a reduction in firms' mark-ups over marginal costs. We address explicitly the uncertainty with respect to the timing of the changeover and allow for a possibly continuous regime shift in a smooth transition analysis. Where regime shifts can be found, the velocity of transition is extremely high, making the linear model a justifiable approximation. We also test for discrete structural breaks in the time window from 1986 to 1996, taking up endogeneity concerns in a generalized method of moments framework. Mark-up reductions are found for aggregate manufacturing (although it is also suggested that mark-ups increased in some manufacturing industries in the precompletion period at the end of the 1980s) and also for construction. In contrast, mark-ups have gone up in most service industries since the early 1990s, which confirms the weak state of the Single Market for services and suggests that anti-competitive defence strategies have emerged in EU service industries. [source] Prevalence of cigarette smoking by occupation and industry in the United States,AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 3 2001Ki Moon Bang PhD Abstract Background This study was undertaken to estimate the most recent prevalence of cigarette smoking by occupation and industry in the US, using the data from the third National Health and Nutrition Examination Survey (NHANES III), 1988,1994. Methods Included in NHANES III are data on the cigarette smoking status, occupation, industry, and other demographic information of US non-institutionalized civilians obtained through household interview surveys. The study population included 20,032 adults aged 17 years and older. To estimate the prevalence of cigarette smoking across occupation and industry groups, we used the Survey Data Analysis (SUDAAN) software. Results The prevalence of cigarette smoking was highest among material moving occupations, construction laborers, and vehicle mechanics and repairers. The lowest smoking prevalence was found among teachers. Among industry groups, the construction industry had the highest prevalence of cigarette smoking. Conclusions These findings provide information useful for targeting education activities focusing on adverse health effects of cigarette smoking and also for indirect adjustments in analysis of morbidity and mortality by occupation.

[source] Industrial Diversification and Its Impact on Productivity Growth in Taiwan's Electronics Industry,ASIAN ECONOMIC JOURNAL, Issue 4 2005Show-Ling Jang O12; L63 The present study attempts to link plant-level production diversification to productivity growth in Taiwan's electronics industry. An account of the role of the Taiwanese government over the last 2 decades leading to the take-off of its electronics industry is briefly discussed. We reviewed production activities of more than 20 000 Taiwanese electronics plants during the period 1992,1999. In an inter-industry comparison, we find that at the four-digit and seven-digit industry levels, Taiwanese electronics production plants exhibit a significantly higher degree of product diversification than plants in the manufacturing sector as a whole. Econometric results positively identify diversification as a source of significant productivity growth across all electronics plants classified in the related industry groups. [source] | ||||||||||
