This brief exploratory empirical note seeks to identify key determinants of geographic differentials in the percentage growth rate of state-level employment in the US, with the primary focus being on the percentage net growth rate in the number of small firms (i.e., those with fewer than 20 employees) in each state, where this variable serves as a de facto reflection of ‘entrepreneurship’. In the interest of identifying other key factors that influence state-level employment growth rates, the effective income tax rate in each state, quality of life elements and labour market considerations are also included in the analysis. The study period runs from the year 2000 to the year 2007, ending just prior to the ‘Great Recession’. The estimation results imply that the state-level employment growth rate in the US was an increasing function of the percentage net growth rate in the number of small firms in each state. Thus, it appears that the small firms growth rate may in fact be a significant source.  相似文献

This article documents the popularity of five types of trail-based recreation relative to other forms of recreation that tourists frequently participate in on their trips; identifies these trail users’ cross-participation in other outdoor recreation activities; and profiles the travel behaviour, media habits, trip planning behaviour, and demographic and socioeconomic characteristics of day hikers and snowmobilers as two particularly large trail user segments. Findings are based on data from a household telephone survey conducted in Michigan, surrounding states, and Ontario, Canada. Hiking/backpacking was found to be the most popular natural resource-based recreation activity that respondents participated in on pleasure trips taken during the past 12 months; other forms of trail-based recreation were significantly less popular; mountain bikers participated in nature-oriented recreation activities in Michigan at levels that were similar to those of hikers/backpackers; and snowmobiling appeared to be the focus of most pleasure trips on which this activity occurred, in contrast to day hiking, which appeared to be more of an ancillary pursuit.  相似文献

The paper presents an analysis of the effects of televised alcohol beverage advertising on the consumption of alcohol among a sample of US teenagers. While no effects of exposure on total consumption are demonstrated for the total sample, consistent with other research on alcohol advertising effects, the present analysis reveals the importance of ‘orientations towards advertising’ as linkages between exposure and consumption behaviour. Specifically, a social utility orientation, involving learning of normative expectations about drinking, and a vicarious utility orientation, involving identification with models in alcohol beverage commercials, are shown to be mediating factors which condition the effects of advertising exposure.

This paper proposes that customers often respond to brand extension concepts by visualizing the product. We call this process spontaneous visualization and suggest that it precedes concept evaluations. In two studies, we show that spontaneous visualization is enhanced by the fit between the parent brand and the extension category and by the ease with which the product category can be imagined. The appeal of the visualized image in turn determines whether visualization enhances or decreases concept evaluations. In addition, we find a stronger link between product evaluations and delayed choice when evaluations are based on visualization; evaluations based on visualization hence appear to be more “valid” in the sense of predicting subsequent behavior. Implications of these findings and ideas for future research are discussed.

Democracy, foreign direct investment and natural resources   总被引:1,自引:0,他引:1  
Empirical studies that examine the impact of democracy on foreign direct investment (FDI) assume that the relationship between democracy and FDI is the same for resource exporting and non-resource exporting countries. This paper examines whether natural resources in host countries alter this relationship. We estimate a linear dynamic panel-data model using data from 112 developing countries over the period 1982-2007. We find that democracy promotes FDI if and only if the value of the share of minerals and oil in total exports is less than some critical value. We identify 90 countries where an expansion of democracy may enhance FDI and 22 countries where an increase in democratization may reduce FDI. We also find that the effect of democracy on FDI depends on the size and not the type of natural resources.  相似文献

This paper applies a disaggregated approach to segment industrial markets under competitive structures taking the air-freight market for the high-technology product industry in Taiwan as a case study. Data from firms is used to examine the structure of the air freight industry and we find that carriers are clustered into two strategic groups, express and forwarder. Pricing is a leading strategy recognized by customers for forwarders, whereas service punctuality and freight security are the winning strategies for express. The high-tech freight market is classifiable by shipment destination and size.  相似文献

Technical progress lowers costs and prices but appears to have an ambiguous effect on product reliability. This paper presents a simple model which explains this observation. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
