Eastern economies towards european union: Statistical measures of perspective evaluation

The main goal of presented taxonomy methods is to make the integration criteria of countries which are candidates for the European Union (EU) more objective. One of the basic issues in the process of their program construction is to perform suitable numbers and types of measures and coefficients. In this paper, similarity and distance measures between countries are proposed. Some of them are able to estimate the integration program realization, while others could signal possible current corrections to the program being realized. The methods described in this paper could also be useful for countries' program evaluations based on the experiences of the EU members, especially such countries whose processes of integration with the EU are characterized by similar processes and indices of economic development.

Property insurance risk map in determining bonuses and maluses

This project presents a proposal to build the Insurance Risk Map based on such taxonomy measures as similarity measure of the objects (_io) and the distance measure between objects (d_io). Practical usefulness of the presented construction has been illustrated by means of indicating areas where the a/m Insurance Risk Map can be used by insurance companies. These activities are mainly connected with the process of tariff construction as well as fixing the amount of discounts (bonuses) and surcharges (maluses). In this project, the emphasis has been put on the particular process of fixing bonuses and maluses.     

Patterns and determinants of the horizontal and vertical intra-industry trade of regions: panel analysis for Spain & Poland

ABSTRACT

Most of the empirical studies in the literature on intra-industry trade are conducted at the country level. Countries, however, differ in terms of granularity and internal heterogeneity. In the present study we empirically identify the determinants of the overall IIT as well as its horizontal and vertical components in the trade of Spanish and Polish NUTS-2 regions with all existing trade partners over the period 2005–2014. In order to obtain unbiased results, we utilize a semi-mixed effect model, estimated with the PPML method. We estimate the models jointly for all Spanish and Polish regions and then disjointly in a comparative manner – in order to identify incongruities of reaction to the various factors investigated. These include both traditional factors and a number of unorthodox factors such as regional path dependence, quality of regional institutions, the core or peripheral status of the reporting region.     

Reconstruction of previous failure times and records

For the sequences of independent identically distributed random variables with continuous distributions, we provide the optimal upper bounds for the increments of order and record statistics under condition that the values of future order statistics and records are known. The bounds are expressed in terms of quantiles and absolute moments centered about the quantiles of the parent distribution. We also describe the distributions which approach the bounds with arbitrary desired accuracy.The second author was supported by the Polish State Committee for Scientific Research (KBN) under Grant 5 P03A 012 20Received November 2003     

Probabilistic sophistication and variational preferences

This paper shows that in the class of variational preferences the notion of probabilistic sophistication is equivalent to expected utility as long as there exists at least one event such that the independence axiom holds for bets on that event. This extends the result of Marinacci (2002) [13] and provides a novel interpretation of his result.     

Should Small Countries Fear Deindustrialization?

Will small countries deindustrialize when opening up to trade with large countries? Donald Davis (1998 ) shows that for the home market effect to lead to deindustrialization of small countries, trade costs for homogeneous goods must be sufficiently smaller than trade costs in differentiated goods, a condition which is not supported by empirical evidence. We show that if differentiated goods production uses tradable inputs small countries can become deindustrialized when trading with a sufficiently large country and if trade costs are low.     

Role of resource gap and value appropriation: effect of reputation gap on price premium in online auctions

In this study, we draw on the resource‐based view of the firm and on value‐based models of strategy to examine when firms appropriate value from their superior resources. We argue for the need to take into account the role of the resource gap between competitors rather than the absolute resource stock of the focal firm when examining the resource‐performance relationship. In particular, we investigate whether the ability of a reputable seller to command a price premium is influenced by the reputation gap (i.e., the reputation differences between the focal seller and its closest competitor standardized by the reputation stock of both sellers). We test our hypotheses on 72 matched pairs of online transactions screened from more than 2,000 auctions of new mobile phones on the Polish Internet auction site Allegro. We find that the ability of a reputable seller to command a price premium (1) increases with the size of the reputation gap between the focal seller and its matched competitor, and (2) becomes increasingly smaller for each additional unit of the seller reputation gap.

Mixed systems with minimal and maximal lifetime variances

We consider the mixed systems composed of a fixed number of components whose lifetimes are i.i.d. with a known distribution which has a positive and finite variance. We show that a certain of the k-out-of-n systems has the minimal lifetime variance, and the maximal one is attained by a mixture of series and parallel systems. The number of the k-out-of-n system, and the probability weights of the mixture depend on the first two moments of order statistics of the parent distribution of the component lifetimes. We also show methods of calculating extreme system lifetime variances under various restrictions on the system lifetime expectations, and vice versa.
