This paper reviews the contribution that Prometheus has made over the past 20 years to the literature on innovation, innovation policy and technological change. I offer first a necessarily subjective view of how the research literatures of innovation and innovation policy have developed in...

Most firms in most countries find themselves taking up new technology in the wake of pioneers or first-movers. A central question is how (and whether) such firms can make a success of being followers--in the time-related sense of adopting subsequently. We take a novel approach to this question...

Hall P. V. and Jacobs W. Shifting proximities: the maritime ports sector in an era of global supply chains, Regional Studies. Economic geographers argue that spatial and non-spatial dimensions of proximity are central to innovation and collective action. The various dimensions of proximity in...

Cost function estimation often involves data on a function and a family of its derivatives. Such data can substantially improve convergence rates of nonparametric estimators. We propose series-type estimators which incorporate the various derivative data into a single nonparametric least-squares...

We consider estimation for a class of Lévy processes, modelled as a sum of a drift, a symmetric stable process and a compound Poisson process. We propose a nonparametric approach to estimating unknown parameters of our model, including the drift, the scale and index parameters in the stable...

Let Tn be a U-statistic and Sn its projection (in the sense of Hájek). Limit theory for U-statistics is usually considered in two disjoint cases, termed degenerate and nondegenerate. The traditional method is to treat the cases separately, using different techniques in each to obtain a...
