Industry changes in technology and complementary assets and the creation of high-growth firms 总被引:1,自引:0,他引:1
This study uses employment data to examine why some industries host more new high-growth firms than others. Using a unique data base of 201 industries over a 15-year period, we find that increases in the proportion of employment of scientists and engineers in industries are positively associated with counts of fast-growing new firms; however, we do not detect a relationship between fluctuations in the proportion of employment in sales and production occupations and counts of fast-growing new firms. The findings suggest that technological innovation is an important determinant of entrepreneurial opportunity. Further, they suggest that private new firms are an important means of organizing commercial innovation and that new firms may be less constrained by complementary assets than has been previously understood. 相似文献

Despite the rapid growth of air freight shipments, much of the existing literature on the geography of air transportation has paid more attention to passenger travel than air freight. The purpose of this paper is to elevate our understanding of air freight by determining which specific variables most influence and shape the geographic distribution of air freight by metropolitan area using stepwise regression analysis. The empirical results suggest a regression model of five independent variables was the most parsimonious solution where the final model accounted for 71.1% of the variation in air freight shipments by metropolitan area (MA). The most important predictor was the traffic shadow effect, where less populated MAs under the traffic shadow of larger MAs tended to generate lower levels of freight. The model also suggested that other key predictors included the employment market share in transportation-shipping-logistics industries, per capita personal income, the number of medical diagnostic and supplier establishments, and above average wages in high technology. Overall, metropolitan markets with diverse and efficient ground support systems, freight forwarders and other transportation services, a more affluent population, an intense agglomeration of medical laboratories and related suppliers, and a well paid skilled workforce engaged in computer systems design and electronic product manufacturing are more likely to ship freight by air. 相似文献

This paper analyzes how location has affected, in the second half of the twentieth century, the population growth of 2889 municipalities in Switzerland. The analysis demonstrates the temporal relativity of location attributes, even for small territorial divisions, such as the Swiss cantons. However, we also show that, both absolute and relative location attributes have weakened over time as population growth predictors, apparently due to improving road infrastructures, and growing motorization. The study has been made possible by a detailed historical population and accessibility database available for Swiss municipalities. To the best of our knowledge, no database of such scope and quality is available for any other European country. 相似文献

Indonesia's financial sector has two paradoxes: (i) Indonesia has been a global leader in microfinance for the past 25 years, but access to microfinance services is declining; and (ii) Indonesia's commercial banks are liquid, solvent, and profitable, and the Indonesian economy has been doing well over the past decade, but small and medium enterprises are facing a credit crunch. Although Indonesia is underbanked, most commercial banks have been unresponsive to unmet effective demand. The behavior of banks has been in their own short‐term best interests, primarily because of the unintended consequences of Indonesia's financial sector reregulation after the East Asian crisis and contradictory monetary policies, which have produced a prudentially sound but inefficient, narrow, and homogenized banking oligopoly. Indonesia should not respond to financial exclusion by artificially pumping out and administratively allocating more credit. Instead, it should promulgate smart regulation so that banks maintain their sound risk management without pursuing noncompetitive and noninclusive business practices. 相似文献

In the present research, Construal Level Theory is used to predict that consumers will mentally characterize incentive offers
differently as a function of their redemption time frames. Data from two experiments indicate that concrete features, such
as the face value of an offer or its mode of presentation (as a dollar figure or as a percentage discount), are prominent
for incentives with short time frames but not for incentives with long ones. In the latter case, abstract features, such as
the incentive’s goal congruity or fit with personal values, are more likely to influence responses. 相似文献

Marketing and entrepreneurship have long been recognized as two key responsibilities of the firm. Despite their tight integration in practice, marketing and entrepreneurship as domains of scholarly inquiry have largely progressed within their respective disciplinary boundaries with minimal cross-disciplinary fertilization. Furthermore, although firms increasingly undertake their marketing and entrepreneurial activities across diverse settings, academe has provided little insight into how changes in the institutional environment may substantially alter the processes and outcomes of these undertakings. Herein, we integrate research on marketing activities, the entrepreneurship process, and institutional theory in an effort to address this gap. We first discuss market orientation as enhancing a firm??s opportunity recognition and innovation, whereas marketing mix decisions enhance opportunity exploitation. We then examine how entrepreneurship leads to innovation directed toward market orientation and marketing mix activities. Based on this foundation, we examine differences in marketing and entrepreneurship activities across institutional contexts. 相似文献

We study men's adult mortality and longevity by socio-occupational status during industrialization in Saguenay-Lac-Saint-Jean, Quebec. Data were extracted from the BALSAC database (Université du Québec à Chicoutimi), which comprehensively traces the demographic history of the region since the beginning of the French Canadian settlement in 1840 up to the early 1970s. Using five occupational classes and controlling for year, age at marriage, urban/rural residence, and literacy, we found no evidence for the emergence of a socioeconomic gradient in mortality. At least until the early 1970s, mortality in the region is the lowest for farmers and appears to be driven by occupational risk rather than fundamental social causes. 相似文献

Economic historians have focused research effort on accounting for the growth and significance of Britain's pharmaceutical industry, but little effort has so far been directed at the veterinary medicine industry, which formed an important part of the wider sector. This article addresses that gap. Factors responsible for that sector's relative insignificance until the 1950s included a general tendency to slaughter rather than to treat sick animals, the absence of advanced medicines until the innovation of sulpha drugs and antibiotics, and difficult relations with the wider pharmaceutical industry. Thereafter output of veterinary medicines increased dramatically, arising from an exponential growth in the demand for intensively farmed poultry meat. Since the 1980s a decline in the use of drugs in agriculture has caused the industry to concentrate on the health needs of domestic animals rather than those of livestock. 相似文献
