This paper studies the identification of the costs of simultaneous search in a class of (portfolio) problems studied by Chade and Smith (2006). We show that aggregate data from a single market, or disaggregate data from a single market segment, do not provide sufficient information to identify...

This paper studies the identification of the costs of simultaneous search in portfolio problems (Chade and Smith, 2006). We show that market shares data from a single market do not provide sufficient information to identify the search cost distribution in any interval, even if...

The literature review mainly focuses on studies from the 1990s on developing countries. Available evidence seems to indicate that short modules underestimate consumption with respect to longer ones resulting in lower levels of recorded consumption and therefore less accurate estimates and higher...

Rank association is a fundamental tool for expressing dependence in cases in which data are arranged in order. Measures of rank correlation have been accumulated in several contexts for more than a century and we were able to cite more than thirty of these coefficients, from simple ones to...

Rank association is a fundamental tool to express dependence for ordinal data. Measures of rank correlation have been developed in several contexts for more than a century and we were able to cite more than thirty of these coefficients, from simple ones to relatively complicated definitions...

Tanulmányunk szubjektív jólléti mutató segítségével vizsgálja a hasznosság és a relatív jövedelemi helyzet közti összefüggést magyar adatok alapján. A korábbi hasonló témájú kutatások rámutattak arra, hogy az abszolút jövedelem mellett lényeges szerepet játszik...
