Analysing inefficiency in a non‐parametric spatial‐dynamic by‐production framework: A <i>k</i>‐nearest neighbour proposal

چکیده
Abstract This paper accounts for spatial effects by benchmarking farms against their k ‐nearest neighbours (KNN) and measuring inefficiency in a non‐parametric dynamic by‐production setting. The optimal number of which are compared corresponds to the value that maximises Moran I test autocorrelation good bad output farms' two sub‐technologies. scores output, variable inputs, investments outputs then computed with those calculated based on global technology, benchmarks all together. application focuses an unbalanced panel specialised Dutch dairy over period 2009–2016 contains information exact geographical locations. results suggest exhibit statistically significant differences between KNN model. Specifically, inefficiencies generally deflated when technology is considered, suggesting ignoring can overestimate inefficiency.

In standard discussions (capitalistic economy), business firms and the income distribution property of production factors are dealt with in a manner in which they are independent from each other. and there is no interaction as such between them. Furthermore, no role whatsoever is assumed for externalities. If we accept that there is interaction between production factors, and these 1actors, bec...

Image Understanding in a Nonparametric Bayesian Framework
We explore recently proposed nonparametric Bayesian statistical models of image partitions. These models are attractive because they adapt to images of different complexity, successfully modeling uncertainty in size, shape, and structure of human segmentations of natural scenes. We improve upon them in a number of key ways to achieve performance comparable to state-of-the-art methods. Our first...
