The maker movement has been touted as a harbinger of the next industrial revolution. Through shared access to tools and digital fabrication technologies, makers can act as producers in the sharing economy and potentially increase entrepreneurship rates, catalyze advanced manufacturing, and spur economic development. We develop a model of the maker movement configured around social exchange, technology resources, and knowledge creation and sharing. We highlight opportunities for studying the conditions under which the movement might foster entrepreneurship outcomes and discuss how research on the maker movement can deepen our understanding of entrepreneurial teams and corporate entrepreneurship.  相似文献

Comparing results from the UK and the USA, this study shows that even subtle cultural differences between two very similar countries can affect new forms of advertising such as interactive television (iTV) commercials. The UK pioneered the mainstream use of iTV advertising, and now it is a mainstream advertising option in the USA on cable networks and online TV networks like Hulu. This study tests whether effective iTV-ad execution factors identified by a previous study of 500 UK iTV campaigns are similarly effective in the USA based on data from 257 iTV campaigns run on the experimental Wink platform between 1998 and 2004. It finds that specific cultural differences make iTV advertising in the USA unique, but also identifies potential globally effective universals for iTV ads. The results of this study allow advertisers to predict the most effective alternative ideas for iTV advertising campaigns run in the USA and potentially in other countries around the world.  相似文献

We examine insider selling for initial public offering (IPO) firms using a sample of 1868 IPOs between 1988 and 2012. We find that overvalued IPOs have higher probability of offering secondary shares, higher proportion of secondary shares offered, and more upward revision in the total number of shares offered. They also have higher probability of insider sale in the open market both before and after lockup expiration. The size of insider sale in the open market also increases with the degree of overvaluation. The results are consistent with the hypothesis that IPO insiders try to sell their shares opportunistically into overvalued markets.  相似文献

This article presents a selective history of the U.S. venture capital (VC) industry, a discussion of the current state of the market, and some predictions about where the market is going. There is no doubt that the U.S. venture capital industry has been very successful. The VC model has provided an efficient solution to a difficult problem—that of enabling people with promising ideas but often limited track records to raise capital from outside investors. A large fraction of IPOs, including many of the most successful, have been funded by venture capitalists, and the U.S. VC model has been copied around the world. Armed with this historical perspective, the authors view with skepticism the recent claims that the VC model is broken. In the past, VC investments in companies have represented a remarkably constant 0.15% of the total value of the stock market; and commitments to VC funds, while more variable, have been consistently in the 0.10% to 0.20% range. Both of these percentages have continued to hold in recent years. And despite the relatively low number of IPOs, the returns to VC funds this decade have largely maintained their historical relationship to the overall stock market. To be sure, VC investment and returns continue to be subject to boom-and-bust cycles. But if the recent period has most of the features of a bust, the authors view today's historically low level of commitments to U.S. VC funds as a fairly reliable indicator of relatively high expected returns for the 2009 and (probably) 2010 vintage years. Perhaps the most promising future role for venture capital, as the authors suggest in closing, is to increase the productivity of the corporate research and development function through various kinds of partnerships and outsourcing arrangements.  相似文献

The existing empirical research on insurer insolvency relies almost exclusively upon individual insurance company financial data, even though the insurance industry is dominated by group‐affiliated firms. This is the first study to evaluate the benefit of using group‐level data to predict insurer insolvencies for group‐affiliated insurers. The study uses financial ratios from the NAIC FAST scoring system, measured at both the company level and group level, as potential predictor variables. The results indicate that group‐level financial information substantially improves the predictive power of an insolvency prediction model relative to a model that uses only the analogous company‐level variables. In fact, the group‐level variables are found to often be substantially more powerful than company‐level variables in predicting individual insurer insolvencies. These results suggest that future insolvency analysis should, whenever feasible, include group‐level information to obtain higher predictive accuracy.  相似文献

Interbank market integration, loan rates, and firm leverage   总被引:1,自引:0,他引:1  
This paper investigates the effect of interbank market integration on small firm finance in the build-up to the 2007-2008 financial crisis. We use a comprehensive data set that contains contract terms on individual loans to 6047 firms across 14 European countries between 1998:01 and 2005:12. We account for the selection that arises in the loan request and approval process. Our findings imply that integration of interbank markets resulted in less stringent borrowing constraints and in substantially lower loan rates. The decrease was strongest in markets with competitive banking sectors. We also find that in the most rapidly integrating markets, firms became substantially overleveraged during the build-up to the crisis.  相似文献

Whonka Candy Company (Whonka) is a case study dealing with internal control and corporate governance. The company has grown rapidly over the last few years and achieved a large share of the wholesale chocolate market. The growth has caused many changes to corporate operations and financial reporting. Your responsibility as a new member of Whonka’s board of directors is to evaluate the company’s current system of control. Use the knowledge you have obtained regarding the Sarbanes–Oxley (SOX) Act (2002) (Sarbanes-Oxley Act of 2002. 2002, July 30. Available at http://www.sec.gov/about/laws/soa2002.pdf) and the COSO Internal Control–Integrated Framework (1992 and 2012) (Committee of Sponsoring Organizations of the Tre. (1994). INTERNAL CONTROL – INTEGRATED FRAMEWORK. Jersey City, NJ: AICPA. Retrieved on June 12, 2012 from http://www.snai.edu/cn/service/library/book/0-framework-final.pdf) and best business practices of accounting system design and operation to develop a report to the board. This case will challenge your ability to think critically and practice your written communication skills.  相似文献
