Previous time series evidence has indicated that farmland pricesand cash rents are not cointegrated, a finding at odds withthe present value model of farmland prices. We argue that thisfailure to find cointegration may be due to low power of testsand to the presence of structural change representing a shiftingrisk premium on farmland investments. To accommodate this possibility,we use panel unit root and cointegration methods that are morepowerful than conventional time series methods and allow forbreaks in the cointegration relationship. Our results, basedon a large panel covering 31 US states between 1960 and 2000,suggest that the present value model of farmland prices cannotbe rejected. 相似文献

Ng (2008) shows how the cross-sectional variance of the observed panel data can be used to construct a simple test for the proportion of non-stationary units. However, in the case with incidental trends the test is distorted. The present note shows how the distortions can be substantially reduced by the use of bias-adjustment. It also investigates the local power of the bias-adjusted test, which is shown to suffer from the same incidental trends problem previously only documented for conventional t-tests. 相似文献

The presence of unobserved heterogeneity and its likely detrimental effect on inference has recently motivated the use of factor‐augmented panel regression models. The workhorse of this literature is based on first estimating the unknown factors using the cross‐section averages of the observables, and then applying ordinary least squares conditional on the first‐step factor estimates. This is the common correlated effects (CCE) approach, the existing asymptotic theory for which is based on the requirement that both the number of time series observations, T, and the number of cross‐section units, N, tend to infinity. The obvious implication of this theory for empirical work is that both N and T should be large, which means that CCE is impossible for the typical micro panel where only N is large. In the current paper, we put the existing CCE theory and its implications to a test. This is done by developing a new theory that enables T to be fixed. The results show that many of the previously derived large‐T results hold even if T is fixed. In particular, the pooled CCE estimator is still consistent and asymptotically normal, which means that CCE is more applicable than previously thought. In fact, not only do we allow T to be fixed, but the conditions placed on the time series properties of the factors and idiosyncratic errors are also much more general than those considered previously. 相似文献

Network board continuity and effectiveness of open innovation in Swedish strategic small-firm networks 总被引:1,自引:0,他引:1
Increasing adoption of open innovation as an alternative route to research and development necessitates the development of new ways to organize innovation, as well as reassessment of existing ways. Much like traditional corporations that subscribe to the closed innovation paradigm, novel organizational arrangements targeting open innovation, such as small-firm networks, employ boards to effectively manage joint research-and-development activities. These boards are similar yet different from traditional corporate boards; as such, they may have different requirements for proper functioning. We use 5-year longitudinal data on 53 Swedish strategic small-firm networks to investigate how the boards should be organized to help improve the innovative status of network participants. We expand the set of tools available for effective organization of the boards' operations and emphasize the effects of network board continuity (rates of renewal) on network members' innovative performance. We argue that the relationship is curvilinear (U-shaped) and demonstrate that it is more pronounced in larger networks. 相似文献

This paper investigates why and how founding entrepreneurs bond with their ventures. We develop and test theory about the nature of bonding in a functional magnetic resonance imaging (fMRI) study of 42 subjects (21 entrepreneurs and 21 parents). We find that entrepreneurs and parents show similar signs of affective bonding, that self-confidence plays a role in bonding style, and that the degree to which entrepreneurs include their ventures in the self and to which parents include their child in the self influences their ability to make critical assessments. Our findings suggest that bonding is similar for entrepreneurs and parents and that venture stimuli influence reward systems, self-regulatory functions, and mental factors that are associated with judgment. 相似文献

We investigate the short‐term relation between individual investor trading and stock returns on the Australian Securities Exchange. Stocks heavily bought by individual investors underperform stocks heavily sold over the subsequent three days, with respective returns on to a long–short portfolio of ?93, ?67 and ?12 basis points on days one, two and three. Individuals underperform in small and mid‐size stocks when they trade passively using limit orders waiting for the market price to move in their favour. Individuals underperform in large stocks when they trade aggressively using marketable orders. Foreign institutions gain from taking the opposite side of individual trades. We present an information asymmetry‐based explanation for the findings. 相似文献

The Heterogeneity of Socially Responsible Investment 总被引:1,自引:0,他引:1

Many writers have commented on the heterogeneity of the socially responsible investment (SRI) movement. However, few have
actually tried to understand and explain it, and even fewer have discussed whether the opposite – standardisation – is possible
and desirable. In this article, we take a broader perspective on the issue of the heterogeneity of SRI. We distinguish between
four levels on which heterogeneity can be found: the terminological, definitional, strategic and practical. Whilst there is
much talk about the definitional ambiguities of SRI, we suggest that there is actually some agreement on the definitional
level. There are at least three explanations which we suggest can account for the heterogeneity on the other levels: cultural
and ideological differences between different regions, differences in values, norms and ideology between various SRI stakeholders,
and the market setting of SRI. Discussing the implications of the three explanations for the SRI market, we suggest that there
is reason to be sceptical about the possibilities of standardisation if not standardisation is imposed top-down. Whether this
kind of standardisation is desirable or not, we argue, depends on what the motives for it would be. To the extent that standardisation
may facilitate the mainstreaming of SRI, it could be a good thing – but we entertain doubts about whether mainstreaming really
requires standardisation. 相似文献

Mindfulness, meaning a receptive attention to and awareness of present events and experience, is reported to have a wide range of benefits, but it has been suggested that it could prove costly in terms of task performance. This article analyzes how dispositional mindfulness relates to taking entrepreneurial action. Based on two waves of survey data, we find that mindful individuals are less likely to engage in entrepreneurial action than less mindful individuals, but when they do start to act, they take as many actions as individuals who score low on trait mindfulness, and even more if they have entrepreneurial experience. 相似文献

ABSTRACTFor a sample of all 88 counties in the State of Ohio over a 5-year period, this study documents the effect of flagship enterprises and concentrated industrial clusters on regional innovation. Consistent with the agglomeration arguments and the knowledge spillover theory of entrepreneurship, both appear to affect regional innovation positively. Additionally, regional educational attainment positively moderates the effect of industrial clusters on innovation. At the same time, flagship enterprises primarily affect regional innovation in regions with low education levels. Results are obtained with the help of conservative econometric techniques and are robust to the choice of alternative dependent variables and estimators. The findings have major policy implications and provide insights into alternative routes to encouraging regional innovation. 相似文献

Prior studies find sizable gaps between entrepreneurial intentions and subsequent actions. We extend models of entrepreneurial intentions by drawing on action phase theory to better understand how entrepreneurial intentions translate into actions. Our study focuses on the effects of implementation intentions on taking entrepreneurial action. The analysis uses two waves of survey data on 422 individuals, from the Swedish general population, who had an explicit interest in starting a business and who reported on their actions 6 months later. We test and find support for a moderated mediation model in which implementation intentions mediate the effects of goal intentions on taking entrepreneurial action. We further find the mediated effect to be even stronger for those confirming a strong intention to start a new business. We provide an in-depth discussion of the concept of implementation intention and an extensive research agenda. 相似文献
