The paper analyses the effects of individual and household characteristics on current poverty status, while controlling for initial conditions, past poverty status and unobserved heterogeneity in 14 European countries for the period 1994–2001, using the European Community Household Panel. The distinction between true state dependence and individual heterogeneity has important policy implications, since if the former is the main cause of poverty it may be crucial to break the ‘vicious circle’ of poverty using income-supporting social policies, whereas if it is the latter anti-poverty policies should focus primarily on education, training, development of personal skills and other labour market oriented policies. The empirical results are similar in qualitative terms but rather different in quantitative terms across the EU countries covered in the paper. State dependence remains significant in all model specifications, even after controlling for unobserved heterogeneity or when removing possible endogeneity bias. Higher poverty rates and higher poverty persistence are associated with particular welfare state regimes, although the link is substantially weakened when other explanatory variables are included in the analysis.

The purpose of this study is to enhance understanding labour supply dynamics of the UK workers by examining whether and to what extent there is state dependence in the labour supply at both the extensive and intensive margins.

A dynamic two-tiered Tobit model is applied to the first seven waves of Understanding Society: the UK Household Longitudinal Study. The model used accounts for observed and unobserved individual heterogeneity and serially correlated transitory shocks to labour supply to draw inferences on state dependence.

The results show that both observed and unobserved individual heterogeneity contributes to observed inter-temporal persistence of the labour supply of the UK workers, and the persistence remains after these factors are controlled for, suggesting true state dependence at both the extensive and intensive margins of the labour supply. The study also finds that at both the margins, the state dependence of labour supply is larger for females than for males and that for both genders the state dependence is larger for people with low education, mature aged workers and people with long-standing illness or impairment. The results also show that estimates from a conventional Tobit model may produce misleading inferences regarding labour supply at the extensive and intensive margins.

This study adds to the international literature on labour supply dynamics by providing empirical evidence for both the extensive and intensive margins of labour supply, while previous studies tend to focus on the extensive margin of labour force participation only. Also, unlike earlier studies that often focus on females, this study compares labour supply dynamics between males and females. The study also compares the estimates from the more flexible two-tiered Tobit model with that from the conventional Tobit model.

The purpose of this paper is to enhance the understanding of labour force participation behaviour of married Australian women, with a focus on identifying the sources of observed inter-temporal labour force participation persistence.

A dynamic Probit model is applied to the Household, Income and Labour Dynamics in Australia (HILDA) Survey, a national representative panel survey of Australian households. The model used accounts for observed and unobserved individual heterogeneity and serially correlated transitory shocks to labour supply.

The results show that both observed and unobserved individual heterogeneity contributes to observed inter-temporal persistence of labour force participation of married Australian women, but the persistence remains even after controlling for these factors. It is also found that failing to control for serially correlated unobserved transitory shocks would lead to underestimation of genuine state dependence of labour force participation; and that state dependence of labour force participation varies with age, education, health, immigration status and the number of children under the school age.

This study adds to the international literature on labour force dynamics of women by providing Australian empirical evidence and through a flexible modelling framework. The result that there exists genuine positive state dependence in married Australian women’s labour force participation suggests that policy intervention that increases married women’s labour supply would have a long-lasting effect.

Purpose – Revisiting Fornell et al.'s (1996) seminal study, this chapter looks at the evidence for observed and unobserved heterogeneity within data underlying the American customer satisfaction index (ACSI) model. Examining data for two specific industries (utilities and hotels) reveals only modest differences. However, we suppose that unobserved heterogeneity critically affects the results. These insights provide the basis for shaping further differentiated ACSI model analyses and more precise interpretations.

Methodology/approach – This study applies the partial least squares (PLS) path modeling method and uses empirical data to estimate and compare the ACSI model results on the aggregate and industry-specific data levels. In addition, the finite mixture PLS path modeling (FIMIX-PLS) method is employed to further examine across industry similarities and within industry differences.

Findings – This research uncovers unobserved heterogeneity that guides forming three segments of customers within each industry. The major segment in each industry represents customers that are fairly loyal (i.e., neither disloyal nor extremely loyal) while the other two smaller segments are not as similar across the two industries. Our study identifies substantial differences across these segments within each industry. An importance-performance map analysis illustrates these differences and provides the basis for managerial implications.

Originality/value of the chapter – The unobserved heterogeneity revealed within industries in a given country (i.e., the United States of America) underlines the need to be open to differences within populations, beyond the observed heterogeneity across distinct groups or cultures, and the need to reconsider reporting requirements in academic research.

This paper aims to model the efficiency of labour offices belonging to the public employment services (PESs) in Spain using a stochastic matching frontier approach.

With this aim in mind, the authors apply a random parameter model approach to control for observed and unobserved heterogeneity.

Results indicate that when the information criteria of the estimates are analysed, it improves by controlling both, observed and unobserved heterogeneity in the inefficiency term. Also, results suggest that counsellors improve the productivity of labour offices and that the share of unemployed skilled persons, unemployed persons aged 44 or younger, as well as the share of unemployed persons in the construction sector, all affect the technical efficiency of PESs offices.

The model extends the previous specifications in the matching literature that capture only observed heterogeneity. Moreover, as far as the authors know, it is the first paper that estimates a matching frontier for the Spanish case. Finally, the database they use is at the office level and includes the work carried out by counsellors, which is a novelty in the analysis of this type of studies at the Spanish level.

The purpose of this paper is to investigate the causes of unemployment persistence among the Belgian labour force. The underlying issue is to determine the eventual existence of a true causal relationship between successive unemployment spells.

The model used is a dynamic random effects probit model controlling for unobserved heterogeneity and the initial condition problem. It was applied to the Panel Study on Belgian Households (1994‐2002).

The results suggest that while observed and unobserved heterogeneity explain between 57 per cent and 82 per cent of unemployment persistence, the remainder is induced by the presence of state dependence. All else being equal, an individual unemployed this year will be between 11.4 and 33 percentage points more likely to be unemployed next year as compared with an employed person.

The presence of a stigmatisation effect of unemployment means that the costs of unemployment are much higher than the simple loss of income and human capital associated with the current job loss. The study demonstrates the importance of concentrating efforts on the prevention of unemployment.

The paper's contribution is to test again the hypothesis of the presence of state dependence in unemployment using a different technique, allowing, among other things, to control for exogenous variables. The paper demonstrates its existence and measures its contribution in the explanation of unemployment persistence in Belgium, besides that of observed and unobserved characteristics.

The author proposes analyzing the dynamics of income positions using dynamic panel ordered probit models. The author disentangles, simultaneously, the roles of state dependence and heterogeneity (observed and non-observed) in explaining income position persistence, such as poverty persistence and affluence persistence. The author applies the approach to Chile exploiting longitudinal data from the P-CASEN 2006–2009. First, the author finds that income position mobility at the bottom and the top of the income distribution is much higher than expected, showing signs that income mobility in the case of Chile might be connected to economic insecurity. Second, the observable individual characteristics have a much stronger impact than true state dependence to explain individuals’ current income position in the income distribution extremes.

This article analyzes transitions into and out of social assistance (SA) in Canada. We estimate dynamic probit models, controlling for endogenous initial conditions and unobserved heterogeneity, using longitudinal data extracted from the Survey of Labour and Income Dynamics (SLID) for the years 1993–2010. The data indicate that there are substantial provincial differences in SA participation with higher participation rates in the eastern part of the country. However, since the mid-1990s, participation rates have fallen substantially in all provinces with only a modest increase at the end of the observation period. Results from the probit models suggest that there is a significant time dependency in social assistance, even after controlling for endogenous initial conditions and unobserved heterogeneity. The extent of this state dependence varies across provinces.
