This article aims to provide some elements of an evolutionary theory of property rights. It applies a systems-based capital-theoretic perspective to explain the formation and transformation of property rights structures. The approach emphasizes how entrepreneurs create capital combinations by connecting capital goods—defined widely to include property rights, such as patents—in their production plans. Their actions change complementarity relations between property rights as used in production. We treat the property rights structure as a complex adaptive system that exhibits increasing structural complexity as it evolves. Entrepreneurs discover gaps in the property rights system. As they organize production to exploit profit opportunities, entrepreneurs regroup existing intellectual property rights (IPR) into new modules, such as patent pools, that encapsulate more complex combinations of basic building blocks of intellectual property. A patent pool constitutes an interpolation of a new meso level within the macro IPR structure. We apply our framework to the first of the patent pools for digital video compression technology used in digital television and DVDs. 相似文献

Koo, Paya and Peel make some very worthwhile points regarding the operation of the SMPC. Their analysis is interesting and helpful. However, the particular structure of the SMPC and the way it operates is, to some extent, determined by practicalities but also, more importantly, by the fact that it tries to operate as a discussion forum bringing together academics, bankers and financial experts rather than simply providing opinions on what the MPC should do. 相似文献

In this paper we test the existence of forward‐looking behaviour in a multivariate model for alcohol and tobacco consumption. The theoretical framework, based on a dynamic adjustment cost model with forward‐looking behaviour, is enhanced to include the intertemporal interactions between the two goods. The analysis of the within‐period preferences completes the intertemporal model, allowing to evaluate the static substitutability/complementarity relationships. The empirical strategy consists in a two‐step estimation procedure. In a first stage, we obtain the parameters of the demand system, while in a second stage Euler equations are estimated. Results, based on a cohort data set constructed from a series of cross‐sections of the Italian Household Budget Survey, reveal a significant complementarity relationship between alcohol and tobacco. Estimation of the Euler equations does not lead to rejection of the hypothesis of intertemporal dependence, providing evidence for a forward‐looking behaviour in alcohol and tobacco consumption. Moreover, we find significant intertemporal interactions that support the adjustment cost setting in a multivariate model with rational expectations. 相似文献

We identify finance professors’ opinions on the efficiency of the stock markets in the United States and assess whether their views on efficiency influence their investing behavior. Employing a survey distributed to over 4,000 professors, we obtain four main results. First, most professors believe the market is weak to semi-strong efficient. Second, twice as many professors passively invest than actively invest. Third, our respondents’ perceptions regarding market efficiency are almost entirely unrelated to their trading behavior. Fourth, the investment objectives of professors are, instead, largely driven by the same behavioral factor as for amateur investors–one's confidence in his own abilities to beat the market, independent of his opinion of market efficiency. 相似文献

Caplan holds that governments are Leviathans, seeking to extend their power by increasing government expenditures beyond the level preferred by voters. We extend Caplan's model by examining the real (percentage) growth rates of government. We also examine whether government size increases at an increasing rate as the minority party weakens. We find evidence that supports and fails to support the original Leviathan hypothesis. We also fail to support our extensions of Caplan's hypothesis. Furthermore, our significant and contrary results have intuitively appealing interpretations. From these results, we conclude that the impact of political party power on government spending is ambiguous. 相似文献

Some stocks have meaningful ticker symbols; for example, LUV (Southwest Airlines), MOO (United Stockyards), and GEEK (Internet America). Such tickers might be a useful signal of the company's creativity, a memorable marker that appeals to investors, or a warning that the company feels it must resort to gimmicks to attract investors. This paper investigates the performance of stocks with memorable ticker symbols during the years 1984–2005 and finds that, on average, their daily returns are higher than for the overall market. 相似文献

Do professional sports leagues design revenue-sharing rules primarily to help financially weaker teams, or do such organizations view revenue-sharing rules as ways to reward teams for being competitive? Baseball's National League and the National Football League provide evidence from the 1950s that revenue-sharing plans may have surprising effects. If strong teams draw well on the road, revenue-sharing plans may provide modest succor to teams in smaller cities and may benefit teams in larger cities. The two leagues' experiences also suggest that owners are willing to enact regressive aspects in their revenue-sharing plans, possibly to forestall moral hazard possibilities arising from automatically helping teams that remain poor draws or that fail to improve. 相似文献

A primary prediction of the theory of sports leagues is that teams with higher revenues will have higher league positions or winning percentages than teams with smaller revenues. Behind this prediction lies the key influence of market size, yet this has been underexplored in the empirical literature on sports leagues. This paper combines detailed census of population data with panel data on team performance for an open sports league, the English Football League, to test the hypothesis that market size matters for team performance. We find a particularly important role for population close to the team's location. The impact of local population is reduced but not eliminated when allowance is made for entry in the form of competition from neighboring clubs. We assess implications of these findings for both European and North American sports league structures. 相似文献

Formative versus reflective measurement models: Two applications of formative measurement 总被引:1,自引:0,他引:1

This paper presents a framework that helps researchers to design and validate both formative and reflective measurement models. The framework draws from the existing literature and includes both theoretical and empirical considerations. Two important examples, one from international business and one from marketing, illustrate the use of the framework. Both examples concern constructs that are fundamental to theory-building in these disciplines, and constructs that most scholars measure reflectively. In contrast, applying the framework suggests that a formative measurement model may be more appropriate. These results reinforce the need for all researchers to justify, both theoretically and empirically, their choice of measurement model. Use of an incorrect measurement model undermines the content validity of constructs, misrepresents the structural relationships between them, and ultimately lowers the usefulness of management theories for business researchers and practitioners. The main contribution of this paper is to question the unthinking assumption of reflective measurement seen in much of the business literature. 相似文献
