DIETER is an open-source power sector model designed to analyze future settings with very high sharesof variable renewable energy sources. It minimizes overall system costs, including fixed and variablecosts of various generation, flexibility and sector coupling options. Here we introduce DIETERpy thatbuilds on the existing model version, written in the General Algebraic Modeling System (GAMS),and ...

Substantial educational inequalities have been documented in Germany for decades. In this article, we examine whether educational inequalities among children have increased or remained the same since the school closures of spring 2020 due to the COVID-19 pandemic. Our perspective is longitudinal: We compare the amount of time children in secondary schools spent on school-related activities at home ...

We estimate the dynamic effects of government spending shocks, using time-varying volatility in US data modeled through a Markov switching process. We find that the average government spending multiplier is significantly and persistently above one, driven by a crowding-in of private consumption and non-residential investment. We rationalize the results empirically through a contemporaneously countercyclical ...

This paper evaluates a widely used, low stakes, teacher peer-to-peer observation and feedback program under Randomized Control Trial (RCT) conditions. Half of 181 volunteer primary schools in England were randomly selected to participate in a two-year program in which three fourth and fifth grade teachers observed each other. We find that two cohorts of students taught by treated teachers perform no ...

Economic inequality is rising globally and due to developments in information technologies and globalization, nowadays individuals are more exposed to such an inequality than ever. Recent studies show that exposure to inequality may shape economic decisions. In this article, we test whether contributions in the public goods game are sensitive to information about inequality of personal benefits between ...

The experimental literature on antitrust enforcement provides robust evidence that communication plays an important role for the formation and stability of cartels. We extend these studies through a design that distinguishes between innocuous communication and communication about a cartel, sanctioning only the latter. To this aim, we introduce a participant in the role of the competition authority, ...

This paper assesses the impact of decarbonization on the energy system and related employment in South Africa. The cost-minimizing, global energy system model (GENeSYS-MOD) is utilized to project two energy mix scenarios and their associated employment implications at provincial level. While the business as usual (BAU) scenario shows a continuous use of coal capacity in the South African power sector ...

This study tests the prediction that perceived corruption reduces ethical behavior. Integrating a standard “cheating” experiment into a broad household survey in rural Thailand, we find tentative support for this prediction: respondents who perceive corruption in state affairs are more likely to cheat and, thus, to fortify the negative consequences of corruption. Interestingly, there is a small group ...

Green hydrogen can help to decarbonize parts of the transportation sector, but its power sectorinteractions are not well understood so far. It may contribute to integrating variable renewable energysources if production is sufficiently flexible in time. Using an open-source co-optimization model of thepower sector and four options for supplying hydrogen at German filling stations, we find a trade-offbetween ...

Labor markets in low- and middle-income countries are characterized by high levels of informality. A multitude of interventions have been implemented to increase the formalization of firms and workers, including information campaigns, simplified registration procedures, reductions of payroll taxes, and interventions enforcing formalization. We compile a database of 170 impact estimates from 38 academic ...
