Shadow Value

A silhouette index is a well-known measure of an internal criteria validation for the clustering algorithm results. While it is a medoid-based validation index, a centroid-based validation index that is called a centroid-based shadow value (CSV) has been developed.  Although both are similar, the CSV has an additional unique property where an image of a 2-dimensional neighborhood graph is possible. A new internal validation index is proposed in this article in order to create a medoid-based validation that has an ability to visualize the results in a 2-dimensional plot. The proposed index behaves similarly to the silhouette index and produces a network visualization, which is comparable to the neighborhood graph of the CSV. The network visualization has a multiplicative parameter (c) to adjust its edges visibility. Due to the medoid-based, in addition, it is more an appropriate visualization technique for any type of data than a neighborhood graph of the CSV.

Shadow Value

We develop a dynamic model of collusion in airport-pair routes for selected US airlines and specify the first order conditions using a state-space representation that is estimated by Kalman-filtering techniques using the Databank 1A (DB1A) Department of Transportation (DOT) data during the period 1979I-1988IV. We consider two airlines, American (AA) and United (UA) and four city-pairs. Our measure of market power is based on the shadow value of long-run profits in a two-person strategic dynamic game and we find evidence of relative market power of AA in three of the four city pairs we analyze.

Breeding Techniques

New wheat-breeding techniques, such as hybridization and genetic modification, show increasing yield potential. This study involves estimating multi-output multi-input production technology by stochastic frontier techniques to evaluate the economic value of this yield potential. An input-oriented distance function is formulated and applied to European Farm Accountancy Data of 23 European countries. Based on the analysis, an average shadow value is derived for the increase in the marginal yield of wheat that corresponded to 18.87 €/ha. Further, technical change, technical efficiency, and returns to scale are measured for different European regions.

Using Data

Crop residues (CR) are an important, internally produced resource with several uses on smallholder, mixed crop-livestock farms, including livestock feed, mulch, fuel and construction material. This study sets out to develop a method to estimate the internal shadow value of CR as feed and as mulch for smallholder households. The study uses a South Asia case study as illustration using data from a set of village and household surveys in three different sites. The estimated shadow prices were higher for CR as mulch than for CR as feed at all three sites. These results reject the null hypothesis that the estimated shadow price for CR as feed is greater than the shadow price for CR as mulch. Since the null hypothesis was formed based on observing household behavior, the rejection of the null hypothesis implies that there are other reasons to explain why more households use CR as feed versus as mulch.
