For identification of a causal effect we employ a panel model with establishment fixed effects and industry-specific time dummies. Our results show that a higher share of women in management significantly reduces the gender pay gap within the firm. An increase in the share of women in first-level management e.g. from zero to above 33 percent decreases the adjusted gender pay gap from a baseline of 15 percent by 1.2 percentage points, i.e. to roughly 14 percent. The effect is stronger for women in second-level than first-level management, indicating that women managers with closer interactions with their subordinates have a higher impact on the gender pay gap than women on higher management levels. The results are similar for East and West Germany, despite the lower gender pay gap and more gender egalitarian social norms in East Germany. From a policy perspective, we conclude that increasing the number of women in management positions has the potential to reduce the gender pay gap to a limited extent. However, further policy measures will be needed in order to fully close the gender gap in pay.}, language = {en} } @article{SinghalPahleKalkuhletal.2021, author = {Singhal, Puja and Pahle, Michael and Kalkuhl, Matthias and Sommer, Stephan and Levesque, Antoine and Berneiser, Jessica}, title = {Beyond good faith}, series = {SSRN eLibrary / Social Science Research Network}, journal = {SSRN eLibrary / Social Science Research Network}, publisher = {SSRN - Elsevier}, address = {Rochester, NY}, issn = {1556-5068}, doi = {10.2139/ssrn.3947800}, pages = {29}, year = {2021}, abstract = {The ambitious climate targets set by industrialized nations worldwide cannot be met without decarbonizing the building stock.

Until then, climate change had been framed mainly as a problem of negative externalities leading to long-term economic costs, which resulted in countries trying to keep the short-term costs of climate action to a minimum. Carney argued that climate change, as well as climate policy, can also lead to short-term financial risks, potentially causing strong adjustments in asset prices. Analysing the effect of a sustainability transition on the financial sector challenges traditional economic and financial analysis and requires a much deeper understanding of the interrelations between climate policy and financial markets. This dissertation thus investigates the implications of climate policy for financial markets as well as the role of financial markets in a transition to a sustainable economy. The approach combines insights from macroeconomic and financial risk analysis. Following an introduction and classification in Chapter 1, Chapter 2 shows a macroeconomic analysis that combines ambitious climate targets (negative externality) with technological innovation (positive externality), adaptive expectations and an investment program, resulting in overall positive macroeconomic outcomes. The analysis also reveals the limitations of climate economic models in their representation of financial markets. Therefore, the subsequent part of this dissertation is concerned with the link between climate policies and financial markets. In Chapter 3, an empirical analysis of stock-market responses to the announcement of climate policy targets is performed to investigate impacts of climate policy on financial markets. Results show that 1) international climate negotiations have an effect on asset prices and 2) investors increasingly recognize transition risks in carbon-intensive investments. In Chapter 4, an analysis of equity markets and the interbank market shows that transition risks can potentially affect a large part of the equity market and that financial interconnections can amplify negative shocks. In Chapter 5, an analysis of mortgage loans shows how information on climate policy and the energy performance of buildings can be integrated into risk management and reflected in interest rates. While costs of climate action have been explored at great depth, this dissertation offers two main contributions. First, it highlights the importance of a green investment program to strengthen the macroeconomic benefits of climate action. Second, it shows different approaches on how to integrate transition risks and opportunities into financial market analysis. Anticipating potential losses and gains in the value of financial assets as early as possible can make the financial system more resilient to transition risks and can stimulate investments into the decarbonization of the economy.}, language = {en} } @misc{Schumacher2019, author = {Schumacher, Reinhard}, title = {Rezension: Shigeyoshi Senga, Masatomi Fujimoto, Taichi Tabuchi (Eds.).: Ricardo and International Trade. - London: Routledge, 2017. - x, 276 S. - ISBN: 978-1-138-12245-1}, series = {Journal of the History of Economic Thought}, volume = {41}, journal = {Journal of the History of Economic Thought}, number = {3}, publisher = {Cambridge Univ.

We show that upfront investments are needed in the near term for limiting temperature overshoot but that these would bring long-term economic gains. Our study further identifies alternative configurations of net-zero CO2 emissions systems and the roles of different sectors and regions for balancing sources and sinks.

Here we present the first comprehensive, comparative analysis of the long-term dynamics of one-time, temporary climate shocks on production factors, and factor productivity, respectively, in a Ramsey-type growth model. Damages acting directly on production factors allow us to study dynamic effects on factor allocation, savings and economic growth. We find that the persistence of impacts on economic activity is smallest for climate shocks directly impacting output, and successively increases for direct damages on capital, loss of labor and productivity shocks, related to different responses in savings rates and factor-specific growth. Recurring shocks lead to large welfare effects and long-term growth effects, directly linked to the persistence of individual shocks. Endogenous savings and shock anticipation both have adaptive effects but do not eliminate differences between impact channels or significantly lower the dissipation time. Accounting for endogenous growth mechanisms increases the effects. We also find strong effects on income shares, important for distributional implications.

To study this channel, we set up a two-period consumption/saving model with wage uncertainty. This extends the standard saving model by also allowing a worker to allocate a fixed time budget between two work-shifts. To test the comparative statics implied by these two different channels, we conduct a laboratory experiment. A novel feature of our experiments is that we tie income to a real-effort style task. In four treatments, we turn on and off the two channels for consumption smoothing: saving and time allocation. Our main finding is that savings are strictly positive for at least 85 percent of subjects. We find that a majority of subjects also uses time allocation to smooth consumption and use saving and time shifting as substitutes, though not perfect substitutes.

Specifically, the role of personality traits and attitudes is analysed. The aim is to understand whether such traits contribute to an under-investment into training. Importantly, general and specific training are distinguished, where the worker's productivity increases in many firms in the former and only in the current firm in the latter case. Additionally, this thesis contributes to the evaluation of the German minimum wage introduction in 2015, identifying causal effects on wages and working hours. Chapters two to four focus on the work-related training decision. First, individuals with an internal locus of control see a direct link between their own actions and their labor market success, while external individuals connect their outcomes to fate, luck, and other people. Consequently, it can be expected that internal individuals expect higher returns to training and are, thus, more willing to participate. The results reflect this hypothesis with internal individuals being more likely to participate in general (but not specific) training. Second, training can be viewed either as a risky investment or as an insurance against negative labor income shocks. In both cases, risk attitudes are expected to play a role in the decision process. The data point towards risk seeking individuals being more likely to participate in general (but not specific) training, and thus, training being viewed on average as a risky investment. Third, job satisfaction influences behavioral decisions in the job context, where dissatisfied workers may react by neglecting their duties, improving the situation or quitting the job. In the first case, dissatisfied workers are expected to invest less in training, while the latter two reactions could lead to higher participation rates amongst dissatisfied workers. The results suggest that on average dissatisfied workers are less likely to invest into training than satisfied workers. However, closer inspections of quit intentions and different sources of dissatisfaction paint less clear pictures, pointing towards the complexity of the job satisfaction construct. Chapters five and six evaluate the introduction of the minimum wage in Germany in 2015. First, in 2015 an increase in the growth of hourly wages can be identified as a causal effect of the minimum wage introduction. However, at the same time, a reduction in the weekly working hours results in an overall unchanged growth in monthly earnings. When considering the effects in 2016, the decrease in weekly working hours disappears, resulting in a significant increase in the growth of monthly earnings due to the minimum wage. Importantly, the analysis suggests that the increase in hourly wages was not sufficient to ensure all workers receiving the minimum wage. This points to non-compliance being an issue in the first years after the minimum wage introduction.}, language = {en} } @techreport{Obst2022, type = {Working Paper}, author = {Obst, Cosima}, title = {Job Satisfaction and Training Investments}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {47}, issn = {2628-653X}, doi = {10.25932/publishup-54912}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-549124}, pages = {46}, year = {2022}, abstract = {Job satisfaction has been found to impact behavioral choices at the workplace.

Hence, I analyze the relationship between a worker's job satisfaction and her training investments.

In contrast, there is an overall positive relationship if dissatisfied workers neglect their duties. Using logit regressions with the Household, Income and Labour Dynamics in Australia (HILDA) survey I find tentative evidence that there is on average an overall positive relationship with a 1 standard deviation increase in job satisfaction being associated with a 1.5\% increased likelihood of participating in training. A closer inspection of the reasons for training as well as quit intentions reveals some hints of a U-shaped relationship.

We find that a uniform price on emissions from both sectors keeps biofuel emissions at 12 kg CO2 GJ-1.

We also find that comprehensive coverage (>90\%) of carbon-rich land areas worldwide is key to containing land-use emissions.
