Consumers’ Sensorical Product Evaluation and Perception

The aim of the research was to determine consumer perceptions of meat products regarding their origin and the potential impact of their origin on the sensory evaluation of other meat properties. Data were collected during the experiment. By testing the correlation model with multiple analyses of variance for repeated measures, it was determined that there was a statistically significant correlation between the factors. The important contribution of the research is the surveyed issue and the approach to researching the impact of product origin on scientific field of marketing and field of consumer behavior. The research represents a deeper investigation of impact of country-of-origin (COO) on consumer perceptions. An integrated approach to the research of the impact of meat origin was chosen to form interlinks between meat origin and its other sensorical properties.     

Methods of Partial Hedging

In this article we survey methods of dealing with the following problem: A financial agent is trying to hedge a claim C, without having enough initial capital to perform a perfect (super) replication. In particular, we describe results for minimizing the expected loss of hedging the claim C both in complete and incomplete continuous-time financial market models, and for maximizing the probability of perfect hedge in complete markets and markets with partial information. In these cases, the optimal strategy is in the form of a binary option on C, depending on the Radon-Nikodym derivative of the equivalent martingale measure which is optimal for a corresponding dual problem. We also present results on dynamic measures for the risk associated with the liability C, defined as the supremum over different scenarios of the minimal expected loss of hedging C.
