Labour, vol. 37, pp. 1-24 (2023).

Abstract. This article examines the impact of a firm’s position in Global Value Chains (GVCs) on wages according to workers’ origin. Based on a unique linked employer–employee dataset regarding the Belgian manufacturing industry covering the 2002–2010 timespan, our estimates show that firms that are more upstream in the value chain pay on average significantly higher wages. However, the wage premium associated with upstreamness is also found to be unequally shared among workers. Unconditional quantile regressions and decomposition methods suggest that high-wage workers born in developed countries benefit the most from being employed higher up the value chain, while workers born in developing countries appear to be unfairly rewarded.

Abstract. This paper analyses the wage effects of educational mismatch by workers’ origin using a sizeable, detailed matched employer–employee dataset for Belgium. Relying on a fine-grained approach to measuring educational mismatch, the results show that over-educated workers, regardless of their origin, suffer a wage penalty compared to their well-matched former classmates. However, the magnitude of this wage penalty is found to vary considerably depending on workers’ origin. In addition, the estimates show that origin-based differences in over-education wage penalties significantly depend on both demographics (workers’ region of birth, education, gender and tenure) and employer characteristics (firm size and collective bargaining). To our knowledge, the role played by these different moderating variables has been either little or not explored in this context before.

LIDAM Discussion Paper IRES (2022/3).

Abstract. We provide first evidence of the impact of over-education, among natives and immigrants,
on firm-level productivity and wages. We use Belgian linked panel data and rely on the
methodology from Hellerstein et al. (1999) to estimate ORU (over-, required, and undereducation) equations aggregated at the firm level. Our results show that the over-education
wage premium is higher for natives than for immigrants. However, since the differential
in productivity gains associated with over-education between natives and immigrants
outweighs the corresponding wage premium differential, we conclude – based on OLS and
dynamic GMM-SYS estimates – that over-educated native workers are in fact underpaid to
a greater extent than their over-educated immigrant counterparts. This conclusion is refined
by sensitivity analyses, when testing the role of immigrants’ background (e.g. region of
birth, immigrant generation, age at arrival in the host country, tenure).

Abstract

Although many studies point to the significant influence of collective bargaining (CB) institutions on earnings inequalities, evidence on how these institutions shape poverty rates across developed economies remains surprisingly scarce. This paper explicitly addresses the relationship between CB systems and working-age poverty rates before and after taxes and transfers in 24 developed countries over the period 1990–2015. Our results show that countries with a more centralized CB system, a more extended bargaining coverage rate and/or a higher trade union density display significantly lower poverty rates. However, these results only hold in a post-tax benefit scenario. Controlling for country and time fixed effects and a wide range of covariates, our estimates indeed suggest that the poverty-reducing effect of CB institutions stems from the political strength of trade unions in promoting public social spending rather than from any direct effect on earnings inequalities. Sensitivity tests for endogeneity and overlapping samples support this conclusion.

Review of Economics of the Household, 21, pp. 291-333 (2022).

This paper investigates the potentially non-linear relation between households’ indebtedness and their consumption. To do so, we use panel data from the two waves of the Belgian Household Finance and Consumption Survey. Unlike previous studies, we find a negative effect of households’ indebtedness on their consumption, even in the absence of any negative shock on their assets. Our findings suggest that, without such a shock, it is the day-to-day sustainability of the debt, rather than its overall sustainability, that leads households to reduce their consumption. The effect thus seems to occur through precautionary motives. To explore potential non-linearities in this effect, we perform a threshold analysis, whose results suggest that households should not have a debt-service-to-income ratio greater than 30% as this leads to a substantial reduction in their consumption. The effect appears to be robust to various specifications, including the inclusion of other European countries, to result from a trade-off between housing and consumption, and to be more prevalent among fragile households.

This paper is the first to estimate the impact of a direct measurement of firm-level upstreamness (i.e. the steps—weighted distance—before the production of a firm meets either domestic or foreign final demand) on productivity and wage costs. To this end, we merged detailed Belgian linked panel data, covering all years from 2002 to 2010, with a unique dataset containing accurate information on the yearly position of each firm in the value chain. We rely on the methodological framework pioneered by Hellerstein et al. (Journal of Labor Economics, 1999, 17, 409) to estimate panel data models at the firm level. Controlling for key worker and firm characteristics, our GMM-SYS and FE-IV estimates show that firms positioned more upstream (i.e. further away from the final consumer) create more value. Our results also indicate that the impact of firm-level upstreamness is stronger on productivity than on wage costs, which implies that profitability is fostered. More precisely, in line with Belgium’s strong labour market institutions, our estimates suggest that the productivity gains associated with upstreamness are shared almost equally between wages and profits.

Education Economics, Vol. 30, Issue 6, pp. 561-573 (2022).

This paper is among the first to investigate the impact of over-education and over-skilling on workers’ wages using a unique pan-European database covering twenty-eight countries for the year 2014, namely the CEDEFOP’s European Skills and Jobs (ESJ) survey. Overall, the results suggest the existence of a wage penalty associated with over-education. When the educational and the skills mismatches are interacted with each other in order to distinguish apparent over-education from genuine over-education, the results highlight that the workers with the highest wage penalty are those who are both over-educated and over-skilled.

Industrial, a Journal of Economy and Society Relations, Vol. 62, Issue 1, pp. 3-33 (2022).

Using rich longitudinal matched employer-employee data on Belgian firms, we explore the impact of workers’ tenure on firm productivity. To do so, we estimate production functions augmented with firm-level measures of tenure. We deal with the endogeneity of standard inputs and tenure, which arises from unobserved firm heterogeneity and reverse causality, by applying a modified version of Ackerberg et al.’s (2015) control function method, which explicitly removes firm fixed effects. Consistently with recent theoretical predictions, our analyses point to positive, but decreasing, returns to tenure. We also find that the impact differs widely across several firm dimensions. Tenure is particularly beneficial for productivity in contexts characterized by a certain degree of routineness and low job complexity. Along the same lines, our findings indicate that tenure exerts stronger positive impacts in industrial and capital-intensive firms, as well as in firms less reliant on ICT-intensive and knowledge-intensive processes.
