This paper states that under several conditions that completely apply to CPGs, incremental retail sales generated by promotional price discounts are entirely incremental to the promoting manufacturer, the promoting retailer and the category, overall. In general, and as observed examining...

Die vorliegende Dissertation will einen Beitrag zur Messung von Krankheitsbelastung, Einkommensstruktur und Ausbildungsrenditen im ländlichen Westafrika leisten. Ihr Forschungsgegenstand ist die Erhebung und Analyse von Mortalitäts-, Morbiditäts- und sozio-ökonomischen Daten im...

In July 2009, a team of 38 researchers carried out the Global Entrepreneurship Monitor (GEM) survey in the Kingdom of Tonga. The GEM survey estimates the proportion of the general population involved in business start-ups and new firm creation. This paper describes not the results of the survey...

In 2009, a team of 38 researchers carried out the Global Entrepreneurship Monitor (GEM) survey of social and business entrepreneurial activity in the Kingdom of Tonga. The GEM survey estimates the proportion of the population involved in business and social start-ups and new firm creation. This...

Does emigration really drain human capital accumulation in origin countries? This paper explores a unique household survey purposely designed and conducted to answer this specific question for the case of Cape Verde. This is allegedly the African country suffering from the largest "brain drain",...

We apply semiparametric efficient estimation procedures for a seemingly unrelated regression model where the multivariate error density is elliptically symmetric to study the efficiency of the foreign exchange market. We consider both cointegrating regressions and standard stationary...

Functional data analysis (FDA) is an active field of statistics, in which the primary subjectsin the study are curves. My dissertation consists of two innovative applications offunctional data analysis in biology. The data that motivated the research broadened thescope of FDA and demanded new...

We consider a random design model based on independent and identically distributed pairs of observations (Xi, Yi), where the regression function m(x) is given by m(x) = E(Yi|Xi = x) with one independent variable. In a nonparametric setting the aim is to produce a reasonable approximation to the...

Statistical flowgraphs represent multistate semi-Markov processes using integral transforms of transition time distributions between adjacent states; these are combinedalgebraically and inverted to derive parametric estimates for first passage time distributions between nonadjacent states. This...

We propose a new method to find spatially adaptive smoothing splines. This new method breaks down the interval [0, 1] into p disjoint sub-intervals. Then we define p functional components in [0, 1], which have two importantfeatures. First, the purpose of each of these p components is to estimate...
