Introduction in Honour of Maria Concetta Chiuri This Special Issue of Labour is in memoriam of Maria Concetta (Etta) Chiuri. Etta was a passionate and serious economist and a wonderful person. She died a year ago at the age of 40. In her too short life Etta produced extremely interesting and deep research in applied micro- economic with strong ties to current policy issues. Her research interests included household economics, migration, and taxation. After graduating from the University of Bari (Italy), Etta completed her Ph.D. at the University of York (UK) with a dissertation on collective models of household behaviour with Peter Simmons serving as her advisor. After returning to Italy, she taught at the University of Bari, where she was a dedicated teacher and a key contributor in developing the Department of Economics. Etta has collaborated in research activities at the international level. She visited DELTA in Paris, the Centre for European Studies at New York University and was a consultant for the World Bank. She was also part of the international project on "Welfare analysis of fiscal and social security reforms in Europe: does the repre- sentation of family decision processes matter?". In 2007 the Luxembourg Income Study awarded her the Aldi Hagenaars Memorial Award which is given for the best L.I.S. Working Paper written by an economist under the age of 40. To honour and remember Etta as an economist and as person, the Department of Eco- nomics and Mathematics of the University of Bari, in cooperation with the Centre for Household, Income, Labour and Demographic economics (CHILD), the Centre for Studies in Economics and Finance (CSEF) and the Associazione Italiana degli Economisti del Lavoro (AIEL) organized a conference in Bari and Tricase (her hometown). During the sessions of the conference Etta's research was continuously cited as well as her influence on students and younger researchers. Our special issue includes seven papers (six were selected among the papers presented in the conference) on her topics of interest: household economics, migration and taxation. Three papers are on topics of household economics . In the first paper Etta and I have analyzed the factors determining the phenomenon of persistence of coresidence of adult children in their parental home, which is an issue of great interest in Mediterranean countries. The second, by Peter Simmons, (one of the invited lecturers), provides examples of households' choice situ- ations which involve a more complicated constraint structure than the standard linear budget constraint and consumption set. In the third, Daniela Vuri explores the impact of distance to LABOUR 24 (Special Issue) 1-2 (2010) @ 2010 CEIS, Fondazione Giacomo Brodolini and Blackwell Publishing Ltd, 9600 Garsington Rd., Oxford OX4 2DQ, UK and 350 Main St., Malden, MA 02148, USA.
