Automation, workers' skills and job satisfaction.
2020
When industrial robots are adopted by firms in a local labor market, some workers are displaced and become unemployed. Other workers that are not directly affected by automation may however fear that these new technologies might replace their working tasks in the future. This fear of a possible future replacement is important because it negatively affects workers’ job satisfaction at present. This paper studies the extent to which automation affects workers’ job satisfaction, and whether this effect differs for high- versus low-skilled workers. The empirical analysis uses microdata for several thousand workers in Norway from the Working Life Barometer survey for the period 2016–2019, combin…
A method of data structuring for the study of diffusion processes of raw materials and manufactured objects
2017
International audience; Workgroup 3 of the ArchaeDyn II programme aims at studying the diffusion systems of products in ancient times. In order to be able to structure data in GIS in an appropriate way, we propose to go through three levels of modelling: the first one aims at gathering together the different components of the diffusion systems taking into account their interactions; the second corresponds to a conceptual data model created with the help of the HBDS method, that will, as we get to the third stage, lead to the creation of a "three-dimensional" geodatabase. Here we point out the fact that the approach through the simple notion of “site” is not sufficient to study the products’…
Aggregate Behavior and Microdata
2004
Abstract It is shown how one can effectively use microdata in modelling the change over time in an aggregate (e.g. mean consumption expenditure) of a large and heterogeneous population. The starting point of our aggregation analysis is a specification of explanatory variables on the micro-level. Typically, some of these explanatory variables are observable and others are unobservable. Based on certain hypotheses on the evolution over time of the joint distributions across the population of these explanatory variables we derive a decomposition of the change in the aggregate which allows a partial analysis: to isolate and to quantify the effect of a change in the observable explanatory variab…
Additive noise and multiplicative bias as disclosure limitation techniques for continuous microdata: A simulation study
2004
This paper focuses on a combination of two disclosure limitation techniques, additive noise and multiplicative bias, and studies their efficacy in protecting confidentiality of continuous microdata. A Bayesian intruder model is extensively simulated in order to assess the performance of these disclosure limitation techniques as a function of key parameters like the variability amongst profiles in the original data, the amount of users prior information, the amount of bias and noise introduced in the data. The results of the simulation offer insight into the degree of vulnerability of data on continuous random variables and suggests some guidelines for effective protection measures.
The Territorial Organization of Public Tourism Statistics in Spain: A Problem of Date Generation and Use in Geomarketing
2021
The changes produced in the last decade in tourism have generated new demands for statistical information that is comparable over time and space, on a microdata scale and focused on knowledge of tourist behaviour. However, the decentralization of the production of tourism statistics in Spain, derived from the division of powers between the Spanish state and the autonomous communities, has produced the emergence of various and multiple alternative entities for the generation and transfer of tourism data. This fragmentation produces a high dysfunctionality and inefficiency, due to, among other circumstances, a high heterogeneity and duplication of data, a heterogeneity of methodology and type…

ESTIMATING INCENTIVE AND WELFARE EFFECTS OF NONSTATIONARY UNEMPLOYMENT BENEFITS
2013
The distribution of unemployment duration in our equilibrium matching model with spell-dependent unemployment benefits displays time-varying exit rates. Building on semi-Markov processes, we translate these rates into an expression for the aggregate unemployment rate. Structural estimation using German microdata allows us to discuss the effects of an unemployment benefit reform (Hartz IV). The reform reduced unemployment by less than 0.1 percentage points. Contrary to general beliefs, the net wage for most skill and regional groups increased. Taking the insurance effect of unemployment benefits into account, however, the reform is welfare reducing for 76% of workers.
Time Use of the Self-Employed
2007
SUMMARY It is a well-documented empirical regularity that it is more satisfying to be self-employed than to work as an employee for an organization. A large part of this difference in job satisfaction is attributed in the literature to the strong perception of independence by the self-employed. In this paper we study people's time use as a source of entrepreneurial independence. By making use of disaggregated sequential microdata on people's time use, we are able to document that the self-employed work longer effective hours, as well as more in the evenings and weekends, than those employed by an organization. Even though being able to decide when to do one's work may be a sign of flexibili…
Heterogeneidad en el impacto de la política de becas en la escolaridad secundaria postobligatoria en España: un análisis por subgrupos poblacionales
2013
El presente trabajo analiza el impacto de las becas sobre la probabilidad de finalizar con éxito el nivel secundario postobligatorio en España en el caso de diferentes subgrupos poblacionales. Se aplica un diseño cuasiexperimental (Propensity score matching) a partir de la Encuesta de Condiciones de Vida (ECV-2006). Los resultados confirman la existencia de efectos diferenciales positivos (con relación al impacto medio) de la política educativa en el caso de las mujeres y de los alumnos provenientes de hogares desfavorecidos, demostrando la existencia de heterogeneidad en el impacto de la política analizada.
A Semantic Web Approach for Geodata Discovery
2013
International audience; Currently, vast amounts of geospatial information are o ffered through OGC's services. However this information has limited formal semantics. The most common method to search for a dataset consists in matching keywords to metadata elements. By adding semantics to available descriptions we could use modern inference and reasoning mechanisms currently available in the SemanticWeb. In this paper we present a novel architecture currently in development in which we use state of the art triplestores as the backend of a CSW service. In our approach, each metadata record is considered an instance of a given class in a domain ontology. Our architecture also adds a spatial dat…
