Joint analysis of occurrence and time to stability after entrance into the Italian labour market: an approach based on a Bayesian cure model with structured stochastic search variable selection

Precarious employment is a serious social problem, especially in those countries, such as Italy, where there are limited benefits from social security. We investigate this phenomenon by analysing the initial part of the career of employees starting with unstable contracts for a panel of Italian workers. Our aim is to estimate the probability of getting a stable job and to detect factors influencing both this probability and the duration of precariousness. To answer these questions, we use an ad hoc mixture cure rate model in a Bayesian framework.     

Globalisation,informalisation and the state in the Indian garment industry

Globalisation has affected the industrial trajectories of developing countries, producing an increasing disarticulation between the management of production and regimes of labour control. While production regimes have been projected into the global arena, labour regimes have remained apparently anchored to regulatory mechanisms provided by local social structures, and gone through increasing processes of informalisation. Examining the case of the Indian garment sector, this paper argues that the informalisation of labour should not be conceived as necessarily taking place ‘in the shadow of the state’. In fact, in the case presented here, the state was a strong active agency behind the process of informalisation, which it supported through formal policies and through its progressive alignment with the interests of capital.     

The Paradox of Children and Life Satisfaction

Empirical analyses of the determinants of life satisfaction routinely include the number of children as one of the socio demographic controls, without explicitly considering that, for a given household income, more children imply a lower level of income per family member. The variable “number of children” then often attracts a negative or insignificant coefficient. Using data from the German Socio Economic Panel 1984–2007 we confirm that the sign of the coefficient for the variable “number of children in the household” is negative when introducing household income without correction for the number of members in a life satisfaction regression. On the contrary, when we equivalise income with the most commonly adopted equivalence scales, so eliminating the monetary cost of raising children, the impact of the variable is positive and significant when a high level of economies of scale is assumed. Our results however lead us to reject slope homogeneity as we find strong differences by gender and region. In particular, the positive effect of children on life satisfaction is stronger for males and East Germans. We interpret these subsample split results as driven by heterogeneous opportunity costs and cultural traits.     

Nature or Nurture? Learning and the Geography of Female Labor Force Participation

One of the most dramatic economic transformations of the past century has been the entry of women into the labor force. While many theories explain why this change took place, we investigate the process of transition itself. We argue that local information transmission generates changes in participation that are geographically heterogeneous, locally correlated, and smooth in the aggregate, just like those observed in our data. In our model, women learn about the effects of maternal employment on children by observing nearby employed women. When few women participate in the labor force, data are scarce and participation rises slowly. As information accumulates in some regions, the effects of maternal employment become less uncertain and more women in that region participate. Learning accelerates, labor force participation rises faster, and regional participation rates diverge. Eventually, information diffuses throughout the economy, beliefs converge to the truth, participation flattens out, and regions become more similar again. To investigate the empirical relevance of our theory, we use a new county‐level data set to compare our calibrated model to the time series and geographic patterns of participation.     

Rudimentary Reading Repertoires via Stimulus Equivalence and Recombination of Minimal Verbal Units

We report a study with sixteen low-SES Brazilian children that sought to establish a repertoire of relations involving dictated words, printed words, and corresponding pictures. Children were taught: (1) in response to dictated words, to select corresponding pictures; (2) in response to syllables presented in both visual and auditory formats, to select words which contained a corresponding syllable in either the first or the last position; (3) in response to dictated-word samples, to “construct” corresponding printed words via arranging their constituent syllabic components; and (4) in response to printed word samples, to construct identical printed words by arranging their syllabic constituents. After training on the first two types of tasks, children were given tests for potentially emergent relations involving printed words and pictures. Almost all exhibited relations consistent with stimulus equivalence. They also displayed emergent naming performances––not only with training words but also with new words that were recombinations of their constituent syllables. The present work was inspired by Sidman''s stimulus equivalence paradigm and by Skinner''s functional analysis of verbal relations, particularly as applied to conceptions of minimal behavioral units and creativity (i.e., behavioral flexibility) in the analytical units applied to verbal relations.     

A hierarchical modelling approach for measuring reliability of and agreement between two types of magnetic field dosimeter

Summary.  The paper describes how to use hierarchical models to assess the reliability of and agreement between two or more types of measurement device. The idea is illustrated by fitting a linear model with nested random effects to a set of data that was obtained from the calibration of two samples of extremely low frequency magnetic field meters. The paper focuses on the formulation of a suitable model that accounts for the various aspects of the calibration protocol and the subsequent interpretation of the parameter estimates. The approach is very flexible and can easily be tuned to the various needs arising in the measurement agreement framework. It can be seen as an extension of the common practice of using a one-way random-effects model to retrieve a measure of agreement.     

A “capability view” on migration: some theoretical issues raised by the Southern Euro Zone highly skilled mobility

The Southern Euro Zone countries show significant delays to adapt their social and productive systems to the EU goal of creating knowledge-based societies. A signal can be the increasingly higher level of skilled labor migration from these countries, especially during the actual crisis. Recent literature on skilled migrations often rejects the concept of “brain drain” (BD) arguing that circulation and exchange of people and knowledge is expected in the era of globalization. Using both conceptual analysis and secondary data, the paper attempts to highlight proportions of the intra-EU BD phenomenon and show how they may challenge the assumptions of circular migration models. It discusses that a BD problem likely exists in the Southern Euro Zone and proposes an alternative framework for its analysis. The main hypothesis behind this review is that the phenomenon relies on substantial lack of social opportunities for high-skilled people in the countries of origin as provoked by multiple factors. In this account, the several drivers of migrants' choice will be conceptualized by adopting a “Capability Approach,” and they will be further analyzed according to its foremost hypotheses regarding rational behavior, human welfare, and development. The resulting theoretical view has to be considered as an expansion of the neoclassical economics “standard view” on high-skilled migrations.
