Redefining the Economical Power of Nations
This paper is (over the formulas) self explaining . The measurement of economies no longer by GDP alone, but by an Index that includes other important factors as well, a So-cial factors relativized GDP. This index cuts out the part of the GDP that is long term fro-zen up by social transfers (using the highly aggregated GINI coefficient).
Social factors relativized GDP: GDP – GDP x GINI = K_Index
Written differently: (1 – GINI) x GDP = K_Index
Inflation indexed Version: (1 – GINI – Inflation) x GDP = K_Index_Infl.
Productivity Index: K_Index / Labor Force = K_PROD
Inflation indexed Productivity Index: K_Index_Infl. / Labor Force = K_PROD_Infl.
Debt-to-K_Index: National debt / K_Index = K_Debt
Debt-to-K_Index_Infl: National debt / K_Index_Infl. = K_Debt_Infl
The impact of marketing oriented product development on new product performance = A marketing orientált termékfejlesztés hatása az új termék teljesítményre
In the new product innovation management literature a lot of empirical studies have supported the importance of marketing orientation as a key success factor of new products. The purpose of this paper is to examine on a Hungarian sample if there is a connection between marketing oriented product development and new product performance. Firms were clustered into two product performance categories. ANOVA analysis showed significant correlation between R&D/marketing interface and new product performance, while variables associated with costumer orientation were not significant. The study was based on data “In Global Competition 2004 – 2006” survey. This paper was presented at the INCODE conference (INCODE, 2008). = Számos felmérés bizonyítja, hogy az új termékek sikerét nagyban elősegíti a marketing orientált fejlesztési gyakorlat. A „Versenyben a világgal 2004-2006” felmérés adatbázisán ennek relevanciáját vizsgáltuk. A vonatkozó szakirodalomból kiindulva, a felmérés kérdőívéből kiválasztottuk azokat a változókat, amelyekkel a marketing orientált termékfejlesztés leginkább jellemezhető. Öt változóval írtuk le a fogyasztó orientációt, míg egy változónk volt a K+F/marketing együttműködésre. Eredményeink szerint azok a vállalatok, amelyeknél a K+F és a marketing részlegek szorosan együttműködnek, jobb termékfejlesztési teljesítményt érnek el. Ugyanakkor a fogyasztó orientáció és a termékfejlesztési teljesítmény között nem találtunk szignifikáns kapcsolatot. A tanulmány megjelent a pécsi INCODE konferencia kötetében (INCODE, 2008)
A note on Talagrand's variance bound in terms of influences
Let X_1,..., X_n be independent Bernoulli random variables and a function
on {0,1}^n. In the well-known paper (Talagrand1994) Talagrand gave an upper
bound for the variance of f in terms of the individual influences of the X_i's.
This bound turned out to be very useful, for instance in percolation theory and
related fields. In many situations a similar bound was needed for random
variables taking more than two values. Generalizations of this type have indeed
been obtained in the literature (see e.g. (Cordero-Erausquin2011), but the
proofs are quite different from that in (Talagrand1994). This might raise the
impression that Talagrand's original method is not sufficiently robust to
obtain such generalizations. However, our paper gives an almost self-contained
proof of the above mentioned generalization, by modifying step-by-step
Talagrand's original proof.Comment: 10 page
