Regression models are employed to quantify the effects of vehicle restrictions on private and public transport passenger flows in Santiago, Chile using trip flow data for cars, buses and the city's Metro rail system. Estimates are derived for the effects of two restrictions: a permanent measure applied from April through August 2008 to vehicles without catalytic converters and additional measures that banned the use of vehicles with catalytic converters between 7:30 am and 9 pm on days declared as environmental “pre-emergencies” due to high air pollution levels. The estimates show that the permanent restriction had no impact on the use of private cars while the additional restriction curtailed their use by 5.5%. Also, on pre-emergency days the flow of passengers to the Metro increased by about 3% while the bus network showed no statistically significant increase. The pre-emergency restrictions thus had an effect on the ridership of the Metro but not on the bus network as alternatives to the use of private cars. 相似文献

This paper examines employees’ reactions to Corporate Social Responsibility (CSR) programs at the attitudinal level. The results presented are drawn from an in-depth study of two Chilean construction firms that have well-established CSR programs. Grounded theory was applied to the data prior to the construction of the conceptual framework. The analysis shows that the implementation of CSR programs generates two types of attitudes in employees: attitudes toward the organization and attitudes toward society. These two broad types of attitudes can then be broken down into four different categories: (1) acceptance of the new role of the organization, (2) identification with the organization, (3) importance attached to the work performed and (4) a sense of social justice. In turn, each of these categories is a grouping of many different concepts, some of which have at first sight little to do with CSR. Finally, the analysis reveals an attitudinal employee typology: the committed worker, the indifferent worker, and the dissident worker. 相似文献

Drawing on recently-available microdata from financial surveys, this paper presents harmonized indicators for household wealth, its components, and its determinants in four Latin American countries (Chile, Colombia, Mexico and Uruguay), using Spain as a comparison benchmark. The paper analyzes the relationship between wealth indicators and sociodemographic characteristics of household heads (age, education, gender, marital status). For Uruguay, we are also able to analyze wealth patterns and intergenerational mobility (inheritance, family businesses and parental education). 相似文献

A study was carried out in Germany in order to assess consumers' acceptance of genetically modified (GM) foods with health benefits (bread, yohurt and eggs). Acceptability of GM foods increases when its source does not involve animal products such as eggs. Three factors have been identified as direct antecedents of the acceptance of GM foods: respondents' attitude towards biotechnology, health consciousness, and time pressure, being the first one the most salient one. Price consciousness has an indirect positive impact (mediated by health consciousness) upon acceptance of GM products. Males were more likely to accept GM foods with health benefits. 相似文献

This article analyzes whether firm innovation is influenced by the transfer of knowledge among cluster firms. To test the hypotheses, we directly estimated the measurement and the structural model parameters where cooperation, workforce mobility, and institutions were defined as manifest indicators of the latent exogenous variable knowledge transfer, modeled as a second-order construct. Firm innovation was defined as a single item endogenous latent variable. We found knowledge transfer to be related to the way firms are managed vis-à-vis (a) the role of institutions as discussion arenas; (b) the adaptability of the workforce; and (c) the indirect cooperation among firms. 相似文献

Estimates are presented of toll and fuel price elasticities of demand for urban freeway use in Santiago, Chile. High-frequency toll and vehicle data were collected from four urban freeways for different route segments and times of day. Estimation was performed using log-linear regression models whose explanatory variables were tolls, fuel prices, city traffic levels and sets of dichotomous variables to control for daily, weekly and monthly seasonality. City traffic is a high frequency control of the activity level of the city. The elasticities to changes in tolls and fuel were all low in absolute value. The toll elasticities were below 0.05 for two freeways and 0.16 for the third, while for the fourth, which had more alternative routes, it was 0.47. The fuel price elasticities were also heterogeneous, with values of approximately 0.45 for two freeways and 0.21 for the third whereas for the fourth, which had the fewest alternatives, it was 0.07. 相似文献

Current research shows that firms are more likely to benchmark against peers that pay their Chief Executive Officers (CEOs) higher compensation, reflecting self serving behavior. We propose an alternative explanation: the choice of highly paid peers represents a reward for unobserved CEO talent. We test this hypothesis by decomposing the effect of peer selection into talent and self serving components. Consistent with our prediction, we find that the association between a firm's selection of highly paid peers and CEO pay mostly represents compensation for CEO talent. 相似文献
