Location Choices of Migrant Nest-Leavers: Spatial Assimilation or Continued Segregation?

We examine ethnic differences in the ethnic composition of the destination neighbourhood upon leaving the parental home using administrative data for the entire birth cohort 1983 living in the Netherlands. The analysis provides little evidence of a clear intergenerational break in the location choices of young men and women from a non-western origin compared to their parents. The neighbourhood choice pattern of those who leave the parental home for independent and shared living arrangements does not differ markedly from that of their parents, while nest-leavers for union formation are more likely to move to neighbourhoods with a relatively small proportion of non-western inhabitants. A decomposition analysis indicates that an overwhelmingly large part of neighbourhood choice is explained by differences in background variables. Particularly, the origin neighbourhood type of nest-leavers seems to be a driving force underlying the choice of destination neighbourhood, given individual and parental socioeconomic characteristics.leaving home, spatial assimilation, migrants

The Monetary Origins of Asymmetric Information in International Equity Markets

Existing studies using low-frequency data show that macroeconomic shocks contribute little to international stock market covariation. Those studies, however, do not account for the presence of asymmetric information, where sophisticated investors generate private information about the fundamentals that drive returns in many countries. In this paper, the authors use a new microstructure data set to better identify the effects of private and public information shocks about U.S. interest rates and equity returns. High-frequency private and public information shocks help forecast domestic money and equity returns over daily and weekly intervals. In addition, these shocks are components of factors that are priced in a model of the cross-section of international returns. Linking private information to U.S. macroeconomic factors is useful for many domestic and international asset-pricing tests.Financial markets; International topics; Market structure and pricing

The Translation of Indonesian Reduplication Into English

Every language has its own way to communicate its expression. Indonesian has reduplication such as pagi-pagi, cantik-cantik, and jalan-jalan. The English translation of this reduplication is not *morning-morning, *beautiful-beautiful, and*walking-walking respectively. In this case, the translators should make an adjustment when they transfer the message of the Indonesian reduplication into English. This study investigates how Indonesian university students, teachers, and professionals translate the Indonesian reduplications into English. It explores the meaning and structure resulted from the translation. The participants are university students, lecturers and employees. They are given questionnaires in which they translate the Indonesian reduplication into English. The analysis involves the morphological, syntactic and semantic aspects of the translation, as well as the deviations that possibly occur in the translation

Variational principle for scale-free network motifs

For scale-free networks with degrees following a power law with an exponent $\tau\in(2,3)$, the structures of motifs (small subgraphs) are not yet well understood. We introduce a method designed to identify the dominant structure of any given motif as the solution of an optimization problem. The unique optimizer describes the degrees of the vertices that together span the most likely motif, resulting in explicit asymptotic formulas for the motif count and its fluctuations. We then classify all motifs into two categories: motifs with small and large fluctuations

Optimal subgraph structures in scale-free configuration models

Subgraphs reveal information about the geometry and functionalities of complex networks. For scale-free networks with unbounded degree fluctuations, we obtain the asymptotics of the number of times a small connected graph occurs as a subgraph or as an induced subgraph. We obtain these results by analyzing the configuration model with degree exponent $\tau\in(2,3)$ and introducing a novel class of optimization problems. For any given subgraph, the unique optimizer describes the degrees of the vertices that together span the subgraph. We find that subgraphs typically occur between vertices with specific degree ranges. In this way, we can count and characterize {\it all} subgraphs. We refrain from double counting in the case of multi-edges, essentially counting the subgraphs in the {\it erased} configuration model.Comment: 50 pages, 2 figure

A view of Estimation of Distribution Algorithms through the lens of Expectation-Maximization

We show that a large class of Estimation of Distribution Algorithms, including, but not limited to, Covariance Matrix Adaption, can be written as a Monte Carlo Expectation-Maximization algorithm, and as exact EM in the limit of infinite samples. Because EM sits on a rigorous statistical foundation and has been thoroughly analyzed, this connection provides a new coherent framework with which to reason about EDAs

Triadic closure in configuration models with unbounded degree fluctuations

The configuration model generates random graphs with any given degree distribution, and thus serves as a null model for scale-free networks with power-law degrees and unbounded degree fluctuations. For this setting, we study the local clustering $c(k)$, i.e., the probability that two neighbors of a degree-$k$ node are neighbors themselves. We show that $c(k)$ progressively falls off with $k$ and eventually for $k=\Omega(\sqrt{n})$ settles on a power law $c(k)\sim k^{-2(3-\tau)}$ with $\tau\in(2,3)$ the power-law exponent of the degree distribution. This fall-off has been observed in the majority of real-world networks and signals the presence of modular or hierarchical structure. Our results agree with recent results for the hidden-variable model and also give the expected number of triangles in the configuration model when counting triangles only once despite the presence of multi-edges. We show that only triangles consisting of triplets with uniquely specified degrees contribute to the triangle counting
