Der volle Inhalt der QuelleThis thesis examines how product portfolios shape emission productivity within the manufacturing sector, questioning policy frameworks that aim to achieve decarbonization primarily through efficiency increases. Using firm-level data from the Portuguese manufacturing sector (2004-2021), it explores heterogeneity in emission intensities within narrowly defined industries and assesses the impact of product composition on firm-level emission productivity. By integrating administrative records on energy consumption, financial data, and product-level sales, the study quantifies the extent to which variations in product portfolios contribute to differences in emission intensity.The findings reveal that firms within the same industry exhibit substantial variation in emission productivity, often exceeding inter-industry differences. Variance decomposition analysis confirms that a significant share of this heterogeneity is explained by firm-level factors rather than sector-wide characteristics. A classification of products into high- and low-emission categories indicates that firms producing a greater share of low-emission goods tend to have systematically higher emission productivity. Through index decomposition analysis and firm-level panel regressions, the study further examines whether adjustments in product portfolios influence firm-level emission intensities over time. The results suggest that aggregate emission reductions have been largely driven by efficiency gains, yet firms that transition toward lower-emission products show sustained improvements in emission productivity.These findings contribute to debates on industrial decarbonization by emphasizing the role of product portfolios alongside efficiency improvements. While technological advancements play a key role, the study highlights how decarbonization strategies that focus solely on efficiency gains may overlook the structural impact of production composition. The results also raise policy questions regarding the extent to which regulatory frameworks encourage or constrain shifts toward lower-emission products. By engaging with perspectives from ecological economics and democratic planning, this thesis offers insights into whether market-driven adjustments alone are sufficient or whether additional regulatory measures are needed to facilitate structural changes in industrial production

Der volle Inhalt der QuelleWith the increasing scale and scope of offshoring, it becomes crucial to get a grasp of its drivers as well as the gains and threats associated with it. The latter are the focal point of the public and academic discussion around offshoring, in particular the potential threats for workers in developed economies. Typical questions that are being raised are whether offshoring leads to job losses in developed countries and whether it favours certain categories of workers and is to the disadvantage of others. These threats are directly linked to the motivations for engaging into offshoring. In this respect, wage costs play a prominent role. But other factors may also influence offshoring decisions, e.g. regulations, in particular those regarding the environment. Last but not least, offshoring may also entail gains for developed economies through the improvements in the efficiency of production. In this PhD thesis, several causes and consequences of offshoring are examined empirically for Belgium.
The first issue that is investigated is whether offshoring of materials and business services affects industry-level employment. An improved offshoring intensity measure is introduced. It is a volume measure of the share of imported intermediates in output split into materials and business services and according to the country of origin of imports, i.e. high-wage and low-wage countries. Estimations of static and dynamic industry-level labour demand equations augmented by offshoring intensities do not reveal a significant impact of either materials or business services offshoring on total employment for Belgium. This result holds for both the manufacturing sector and the service sector and it proves robust to splitting the manufacturing sector into high-technology and low-technology industries.
These results raise the question whether there are actually productivity gains from offshoring. Therefore, estimates of the impact of materials and business services offshoring on industry-level productivity in Belgium are presented. Two features of the analysis are new compared to the existing literature on this subject: the issue is examined separately for manufacturing and market services industries and the possibility of forward and backward spillovers from offshoring, i.e. that productivity gains from offshoring feed through to upstream and downstream industries, is investigated. Results show that materials offshoring has no effect on productivity, while business services offshoring leads to productivity gains in manufacturing. Furthermore, there is no evidence of either forward or backward spillovers from offshoring.
Despite the absence of an industry-level total employment effect, offshoring may alter the within-industry composition of employment. In this respect, a major concern is the worsening of the labour market position of low-skilled workers. This issue is addressed by providing evidence on the impact of offshoring on the skill structure of manufacturing employment in Belgium between 1995 and 2007. Offshoring is found to significantly lower the employment share of low-skilled workers. Its contribution to the fall in the employment share of low-skilled workers amounts to 35%. This is mainly driven by offshoring to Central and Eastern European countries. Business services offshoring also contributes significantly to the fall in the low-skilled employment share. As a complement to the existing literature, the widely used current price measure of offshoring is compared with a constant price measure that is based on a deflation with separate price indices for domestic output and imports. This reveals that the former underestimate the extent of offshoring and its impact on low-skilled employment. Finally, further results show that the impact of offshoring on low-skilled employment is significantly smaller in industries with a higher ICT capital intensity.
Furthermore, attention is drawn to environmental effects of offshoring by asking whether offshoring contributes to reducing air emissions from manufacturing. Indeed, since the mid-90’s, production-related air emissions in Belgian manufacturing have been reduced substantially. It can be shown that the pace of the reduction has been fastest for domestic intermediates. The issue of whether offshoring has played a role in this reduction by replacing domestic intermediates by imported intermediates is widely debated. Here, a decomposition analysis is developed to measure the contribution of offshoring – the share of imported intermediates in total intermediates – to the fall in air emissions for domestic intermediates. Based on the results from this decomposition analysis, it is possible to calculate that 17% of the fall in greenhouse gas emissions, 6% of the fall in acidifying emissions and 7% of the fall in tropospheric precursor emissions in Belgian manufacturing between 1995 and 2007 can be attributed to offshoring.
Finally, emission intensities are also considered as a potential determinant of offshoring. An econometric approach for testing the pollution haven effect for imported intermediate materials is developed. The approach is new with respect to the existing literature on pollution havens through its specific focus on imports of intermediates. The test is embedded in a cost function framework from which a system of cost share equations for variable input factors is derived. The set of potential determinants of the demand for imported intermediate materials includes emission intensities for three types of air pollutants. Their impact constitutes a test of the pollution haven effect. The system of cost share equations is estimated by a within ISUR using data for the Belgian manufacturing sector. Results show some albeit relatively weak evidence of a pollution haven effect for imported intermediate materials.

Der volle Inhalt der QuelleRecently, growth in global investments in renewable energy (IRE) has been so rapid. In fact, renewable energy (RE) is considered as an alternative to deal with global warming, with the scarcity of natural resources, with the increase in energy demand, with the volatility of fossil fuel prices and with the unequal distribution of energy sources. This study attempts to shed more light on the IRE. The study’s prime goal is to evaluate the return on the IRE. It analyses theoretically and empirically the impact of the IRE on the greenhouse gas (GHG) emissions and on Total Factor Productivity (TFP). The study’s second goal is to evaluate the effectiveness of the policies that support the development of RE. The first chapter showed how the relationship between IREs and CO2 emissions is not linear, but, rather, it follows an inverted U-shaped curve. In other words, IREs have a positive impact on CO2 emissions until the investments reach a certain level, beyond which the IREs impact on CO2 emissions becomes negative. The current study has analyzed this relationship empirically by means of the panel threshold regression (PTR) model. The second chapter explores the relationship between IRE and productivity. Referring to the theory of endogenous growth, the study empirically tested the main hypothesis, that IRE positively affects the TFP growth. The empirical study was conducted on a panel of 43 developed and developing countries, using the GMM-system methodology. Study’s findings confirm that IRE have a positive affect on the Total Factor Productivity growth. Indeed, this positive impact is theoretically explained by the fact that the IRE encourages technology transfer and it generates significant knowledge spillovers. The third chapter of the thesis discusses the role and the impact of the policies that encourage the development of RE on IRE. Specifically, in this chapter we evaluate the effectiveness of these policies to attract renewable energy investments in electricity-generating capacity. The results show that the market instruments increase the IREs, although command or control instruments have no or a negative effect, with the exception of low-income countries. Moreover, a combination of "market-pull" and "market-push" instruments can supports the IREs. We also note that IRE support goes through the instruments that indirectly affect these investments. Indeed, to encourage IREs, it is better to act upstream, by spurring research, development and deployment (RDD) in the RE sector, and downstream, by stimulating the production of renewable electricity, through Guaranteed Purchase Rates or Feed-in-Tariffs (FIT)

Der volle Inhalt der QuelleThe agricultural lands that occupy more than one third of Earth's terrestrial surface contribute to climate change and are also impacted by those changes, since their production is conditioned by climatic conditions and water resources. The main objective of this thesis is therefore to quantify and analyze the production and also the main components of the carbon and water biogeochemical cycles for crop ecosystems in contrasted climatic years, focusing specifically on the winter wheat crop, in order to identify the best strategies for maintaining crop production and reducing environmental impacts. The study area is located in southwest France. We propose a regional modeling approach that combines: i) high spatial and temporal resolutions optical remote sensing data, ii) simple crop models and iii) an extensive set of in-situ measurements for models' calibration and validation. The combined use of these three 'tools' opens new perspectives for advanced agro-ecosystems modeling and monitoring at regional or global scales
