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…
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.
The formation of aggregate expectations: wisdom of the crowds or media influence?
2017
ABSTRACTThe general elections of 2015 in Spain were elections of change. Two new parties for which voters had no previous historical reference points burst onto the parliamentary scene. Two (partially) opposed theories vie to offer an explanation as to how voters build their aggregate electoral expectations. In this paper, we investigate which mechanism has the greatest influence on the formation of expectations: published opinion or social interactions. Likewise, we also study if there is an ideological bias in the voters’ perception of the future results of the electoral battle. Based on analysis of microdata from a survey (sample size = 14,262) conducted in Spain on the occasion of the g…
The Sustainability Factor: How Much Do Pension Expenditures Improve in Spain?
2020
The reform of 2013 represented a qualitative leap in the reform of the Spanish pension system. Unlike its predecessors, it introduced two automatic resetting mechanisms similar to those of other European countries. The first is the sustainability factor, scheduled to come into effect in 2019 but delayed until 2023, and its ultimate reversal cannot be ruled out. The objective of this study was to quantify the savings, or the lowest expenditure, that can be achieved in the Spanish public contributory pension system by applying it. These savings are measured in terms of cash&mdash
Monetary policy and the redistribution of net worth in the U.S
2021
The view that expansionary monetary policy can exacerbate both income and wealth inequality by increasing asset prices has become increasingly popular. The aim of this paper is to study the distributive effects of monetary policy on wealth inequality. In the first part of this research, we develop a simple framework based on accounting identity to examine the redistributive repercussions of changes in monetary policy on net worth through different channels. Based on this framework, in the second part of the paper, we show empirical evidence concerning the effects of monetary policy on wealth inequality in the US. To derive this, we combined macro and micro data, and proceeded in two steps. …
