This paper presents new evidence on worker-firm complementarities. We combine matched employer-employee data with direct measures of workers' cognitive and noncognitive skills, and propose an empirical approach that separately identifies the firm-level return for each attribute. We find that similar skills command different returns across employers and that workers' sorting into firms depends on returns to both attributes. We derive theoretical restrictions that characterize many-to-one matching in employer-employee data, linking within-firm skill dispersion to between-firm differences in average skills. Estimates support these restrictions. Firm heterogeneity in skill returns raises both the average level and dispersion of earnings.
Abstract This paper estimates the foodmiles (embedded distances) and transport-related carbon emissions of 27 Food Quality Scheme (FQS) products – Protected Designation of Origin (PDO), Protected Geographical Indications (PGI) and organic – and their reference products. It goes further than the existing literature by adopting a value chain perspective, instead of the traditional consumer perspective, and focusing on FQS products. The same methodology is applied across all the case studies. The article specifically investigates the determinants of differences between FQS and their references. FQS products travel significantly shorter distances (−30%) and generate significantly lower transport-related emissions (−23%) than conventional food products. The differences are even greater for vegetal and organic products. The relationship between distance and transport-related emissions is not exactly proportional and highlights the importance of transport modes and logistics, in particular for exports and imports. Finally, we stress the importance of the spatial distribution of the different stages in the value chains (e.g. production, processing). PDO technical specifications delimit a geographical area for production and processing, thereby limiting distances and transport-related emissions compared to conventional food products, but also compared to other types of FQS.
Abstract This article addresses the issue of the profitability of Food Quality Scheme (FQS) products as compared to reference products, which are defined as analogous products without quality label. We approach this question by taking into account the level of the value chain (upstream, processing, and downstream), the sector (vegetal, animal, seafood) and the type of FQS (PGI, PDO, Organic). We collected original data for several products produced in selected European countries, as well as in Thailand and Vietnam. Comparisons depending on value chain level, sector and FQS are possible by using two comparable indicators: price premium and net price premium (including cost differential). The following principal conclusions were reached: 1) Price is higher for FQS products than for the reference products, regardless of the production level, the type of FQS or the sector; 2) Price premiums generated by FQS do not differ along the value chain, nor between sectors (vegetal, animal or seafood/fish); 3) Price premium for organic products is significantly higher than for PGI products, and this conclusion holds at upstream and processing levels, taking into account the costs directly related to production; 4) All organic products and almost all PDO and PGI products analysed benefit from a positive quality rent; 5) At upstream level and processing level, the relative weight of intermediate consumption in the cost structure is lower for organic products than for reference products.
Abstract Food quality schemes (FQS: organic and geographical indication products) are often supposed to be more sustainable by their political advocates. We explore the social sustainability advantage of FQS through the lens of supply chains’ bargaining power (BP) distribution. We propose an indicator synthesizing different sources underlying BP (competition-based, transactional, institutional) and counting two dimensions (fair BP distribution and adaptation capacity), that we apply to 18 FQS supply chains and corresponding reference. FQS perform better than their reference products on both dimensions. This better performance is due to a combination of sources.

This paper explores the consequences of the under-representation of women in top jobs for the overall gender pay gap. Using administrative annual earnings data from Canada, Sweden, and the United Kingdom, it applies the approach used in the analysis of earnings inequality in top incomes, as well as reweighting techniques, to the analysis of the gender pay gap. The analysis is supplemented by classic O-B decompositions of hourly wages using data from the Canadian and U.K. Labour Force Surveys. The paper finds that recent increases in top earnings led to substantial “swimming upstream” effects, therefore accounting for differential progress in the gender pay gap across time periods and a growing share of the gap unexplained by traditional factors.
Over the last two decades, earnings in the United States increased at the top and at the bottom of the wage distribution but not in the middle - the intensely debated middle class squeeze. At the same time there was a substantial decline of employment in middle-skill production and clerical occupations - so-called job polarization. I study whether job polarization has caused the middle class squeeze. So far little evidence exists about this because the endogenous selection of skills into occupations prevents credible identification of polarization’s effect on wages. I solve the selection-bias problem by studying the changes in returns to occupation-specific skills instead of the changes in occupational wages using data over the two cohorts of the National Longitudinal Study of Youth (NLSY). This data features multidimensional and pre-determined test scores, which predict occupational sorting and thus measure relative occupation-specific skills. My estimation equations are derived from the Roy (1951) model over two cross-sections with job polarization amounting to a shift in the occupation-specific skill prices. In line with polarization, I find that a one percentage point higher propensity to enter high- (low-) as opposed to middle-skill occupations is associated with a .29 (.70) percent increase in expected wages over time. I then compute a counterfactual wage distribution using my estimates of the shifts in occupation-specific skill prices and show that it matches the increase at the top of the wage distribution but fails to explain the increase at the bottom. Thus, despite the strong association of job polarization with changes in the returns to occupation-specific skills, there remains room for alternative (e.g. policy related) explanations about the increase in the lower part of the wage distribution.
