The goal of this paper is the study of a transformation concerning the general K-fold finite sums of the form
Sigma (N >= n1 >= ... >= nK >= 1) 1/b(nK) . Pi (K-1)(J=1) 1/a(nj),
where (K,N) is an element of N-2 and {a(n)}(n=1)(infinity), {b(n)}(n=1)(infinity) are appropriate real sequences. In the application part of our paper we apply the developed transformation to two special parametric multiple zeta-type series that generalize the well-know formula zeta(star)({2}(K), 1) = 2 zeta(2K + 1), K is an element of N. As a corollary of our parametric results, we also prove several sum formulas involving multiple zeta-star values.

A small open economy is highly dependent on foreign environments. This article investigates equilibrium relations between a small open economy and its foreign trade partners. Based on long-run relationships developed by Garratt et al. (2003) a structural model for the Czech Republic (CR) and Slovak Republic (SR) is constructed for period 2002Q1 to 2015Q4. As most of the macroeconomic variables are nonstationary, the Cointegrated Vector Autoregressive Approach (CVAR) is used for empirical analysis. The following five long-run equilibrium relations are examined: relative purchasing power parity, uncovered interest rate parity, Fisher inflation parity, money market equilibrium, and output relation. The estimation results of the long-run relations confirmed similarities between these economies.

The popularity and business impact of major sports have been growing globally over time. This paper focuses on ice hockey, specifically the National Hockey League in North America. It reports a striking irregularity in ice hockey's scoring dynamics relative to comparable sports such as soccer and rugby, namely a scoring surge in the middle section of the game. We explore an explanation for this irregularity related to the convention on the spatial location of the teams' benches (which are fixed throughout the game) and on-ice sides (which are switched every period). Because a large number of the players' substitutions occur while the play is in progress, this convention determines the distance forwards and defenders need to travel to make a substitution, and thus indirectly substitution strategies and scoring. We consider two simple operational changes that could increase the number of goals in the NHL by approximately 5 and 10%, respectively, corresponding to roughly 350 and 700 additional goals each season. This would partly offset the current downward scoring trend and thus enhance the game's attractiveness. The estimated impact of the proposed reforms, one of which is largely costless, is robust across several specifications-using per-minute and per-second scoring data and controlling for various factors, such as bookmakers' odds.

This article investigates the validity of the money superneutrality concept for the large panel of European economies. While focusing exclusively on endogenous growth theories including the Mundell-Tobin effect, we examine the long-run response of real output to a permanent inflation shock in every studied country using a structural vector autoregressive framework. For the majority of countries in our sample, the longrun superneutrality concept is confirmed since the original increase/ decrease in output growth fades in time. We also test the additional hypothesis of whether the group of countries with smaller in-sample inflation mean forms the exception to the long-run money superneutrality. As the result, modern economies might be better described from the viewpoint of Sidrauski.
