1. 1. Estimating income inequality : large sample inference in finite populations

   Författare :Arne Sandström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; order statistics and concomitant of order statistics; functionals; stochastic differentials; weighted empirical distribution function; income inequality; Gini coefficient;

   Sammanfattning : During the last decades the interest in measuring income inequality has substantially increased. In this work we consider measures related to the Lorenz Curve, e g the Gini coefficient. These measures are decomposable^ g the inequality in disposable income can be assigned to various income sources. LÄS MER

3. 2. Sound Quality of Flue Organ Pipe. An Interdisciplinary Study on the Art of Voicing

   Författare :Vincent Rioux; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; listening tests; psychoacoustics; verbal descriptors; flue organ pipes; musical acoustics; sound quality; deterministic stochastic separation; timbre; time-frequency analysis;

   Sammanfattning : This thesis presents a research study carried out in collaboration with a department of applied acoustics, a department of musical acoustics and an organ workshop. The description of the sound quality of flue organ pipes has received fairly little attention either in organ-building or scientific literature, despite its importance in the overall quality of the instrument, probably due to the difficulties inherent in doing so.

5. 4. Essays on Land Lease Markets, Productivity, Biodiversity, and Environmental Variability

   Författare :Mintewab Bezabih; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; JEL-codes: C7; C21; C35; C61; C88; C93; D00; D2; Q02; Q12; Q15; Q29; Q51;

   Sammanfattning : Paper 1: Tenure Insecurity, Transaction Costs in the Land Lease Market and Implications for Gendered Productivity Differentials This study assesses the link between land leasing behavior and productivity differentials between male and female-headed households. A double-moral hazard model allows us to show that the landlord’s tenure insecurity leads to a sub-optimal level of effort on the tenant’s part, via its impact on the likelihood of contract renewal.
