This paper presents an empirical account of a phenomenon that we refer to as the ‘reverse tragedy of the commons’ in open innovation. The name signifies the ‘under-exploitation’ of intellectual property (IP) under weak appropriability. The name is this graphic because the tragedy is costly, and can also render IP effectively worthless and block innovation in the short to medium term. We propose that the tragedy is borne out of the interaction between enterprise characteristics, a competitive setting and the framework that is set by the policy intervention. This finding is pertinent to policy-makers with regard to the design of research, development and innovation instruments, as well as managers who must determine how to implement open practices in innovation.  相似文献

The solutions that Jane Jacobs proposed to improve neighborhoods created a paradoxical problem: improvement increased demand for the amenities of the area, which caused land prices to rise. The net result was at least partial displacement of the old residents of the neighborhood with new ones. Jane Jacobs has been criticized for ignoring gentrification, but she was clearly aware of this process and tried to find means to counter it. By combining the ideas of Henry George about land taxation with the ideals of Jane Jacobs about neighborhood diversity, we can mitigate the negative effects of gentrification and direct the energy of market forces into producing a greater supply of desirable neighborhoods.  相似文献

This study examines the association between market risk disclosures (MRDs) and the investment efficiency of financial firms from six emerging markets in the Gulf Cooperation Council (GCC) region. Based on a sample of 553 firm‐year observations over the 2007–2011 period, we find that MRDs are significantly and negatively associated with both under‐investment and over‐investment and that this association is more pronounced for larger firms. We also find that the association between MRDs and under‐investment is moderated during periods of economic distress such as the Global Financial Crisis of 2008 and that the association between MRDs and over‐investment is magnified during periods of reduced financial distress. Our results are consistent with the idea that MRDs reduce information asymmetry, which ultimately improves investment efficiency. We contribute to the literature in an emerging market context by providing empirical evidence on the association between MRDs and investment efficiency across six emerging GCC capital markets. This study also fills a gap in the literature by providing evidence on the factors affecting the investment efficiency of financial firms.  相似文献

This paper shows that the probability of exercise of convertible bonds issued against a firm’s stock directly affects the liquidity of the stock itself. Using the ratio of absolute stock return to its dollar volume as a proxy for stock liquidity I demonstrate that there is a direct and positive relationship between conversion probability and stock liquidity while controlling for firm size, book to market equity value and firm beta. I describe the effect of unlisted convertible debt on the liquidity of listed firms in the US, Korea and Singapore. The effects of conversion probability on stock liquidity are less pronounced for smaller firms, which helps explain time series variations in the liquidity premiums for smaller firms over time. The relationship between convertibles and stock liquidity is mainly attributed to the expected increase in the number of shares available for trade upon conversion and the expected change in the capital structure of the firm.  相似文献

The literature argues that entrepreneurial intentions depend on perceptions of desirability and perceptions of feasibility. Research in other fields suggests that there will be an interaction effect between these two main antecedents of intentions, but such interaction has not been investigated in the context of entrepreneurial intentions. In this paper we explore this interaction effect in an expectancy framework, hypothesizing a negative interaction effect between perceived desirability and perceived feasibility based on regulatory focus theory. A large multi-country sample confirms this negative interaction, and suggests a novel typology of nascent entrepreneurs as natural entrepreneurs, accidental entrepreneurs, and inevitable entrepreneurs.  相似文献

Bob Quinn spent 20 years propagating an ancient Egyptian wheat variety that is generally known as Khorasan wheat. Bob trademarked his wheat variety using the brand name "Kamut®." Kamut® brand wheat contains some nutritional, health, and taste advantages over modern wheat varieties, but lacks some of modern wheat's agronomic advantages. Kamut® brand wheat is organically produced, and is used to make cereals, breads, cookies, snacks, pancakes, bread mixes, bulgur, pasta, and baked goods. Whole wheat products produced from Kamut® brand wheat are less bitter than those produced from modern wheat varieties. Europe represents approximately two-thirds of the market for this product.  相似文献

The Economic Value of Water Quality   总被引:1,自引:0,他引:1  
Stated preference values for water quality ratings based on the US Environmental Protection Agency National Water Quality Inventory ratings provide an operational basis for benefit assessment. Iterative choice survey results for a very large, nationally representative, Web-based panel imply an average valuation of $32 for each percent increase in lakes and rivers in the region for which water quality is rated “Good.” Valuations are skewed, with the mean value more than double the median. Sources of heterogeneity in benefit values include differences in responses to average water quality information and the base level of water quality. Conjoint estimates are somewhat lower than the iterative choice values. The annual economic value of the decline in inland US water quality from 1994 to 2000 is over $20 billion.   相似文献
