In a controlled laboratory experiment we ask participants to give a detailed answer to an open question. The treatment variable is whether or not they see the phrase “thanks in advance.” Our participants react to the treatment by exerting less effort in answering the request even though they perceive the phrase as polite.

BT - Experimental evidence on the role of Future-Time Reference for intertemporal decision-making T2 - CEPA Discussion Papers N2 - Against the background of the increasingly discussed “Linguistic Saving Hypothesis” (Chen, 2013), I studied whether the targeted use of a present tense (close tense) and a future tense (distant tense) within the same language have an impact on intertemporal decision-making. In a monetarily incentivized laboratory experiment in Germany, I implemented two different treatments on intertemporal choices. The treatments differed in the tense in which I referred to future rewards. My results show that individuals prefer to a greater extent rewards which are associated with a present tense (close tense). This result is in line with my prediction and the first empirical support for the Linguistic Saving Hypothesis within one language. However, this result holds exclusively for males. Females seem to be unaffected by the linguistic manipulation. I discuss my findings in the context of “gender-as-culture” as well as their potential policy-implications.

BT - The Forward-Looking Effects of Increasing the Retirement Age on (Un)employment Behaviour T2 - CEPA Discussion Papers N2 - Leveraging two cohort-specific pension reforms, this paper estimates the forward-looking effects of an exogenous increase in the working horizon on (un)employment behaviour for individuals with a long remaining statutory working life. Using difference-in-differences and regression discontinuity approaches based on administrative and survey data, I show that a longer legal working horizon increases individuals’ subjective expectations about the length of their work life, raises the probability of employment, decreases the probability of unemployment, and increases the intensity of job search among the unemployed. Heterogeneity analyses show that the demonstrated employment effects are strongest for women and in occupations with comparatively low physical intensity, i.e., occupations that can be performed at older ages.

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.

T2 - CEPA Discussion Papers N2 - As the policy debate on entrepreneurship increasingly centers on firm growth in terms of job creation, it is important to better understand which variables influence the first hiring decision and which ones influence the subsequent survival as an employer. Using the German Socio-economic Panel (SOEP), we analyze what role individual characteristics of entrepreneurs play in sustainable job creation. While human and social capital variables positively influence the hiring decision and the survival as an employer in the same direction, we show that none of the personality traits affect the two outcomes in the same way. Some traits are only relevant for survival as an employer but do not influence the hiring decision, other traits even unfold a revolving door effect, in the sense that employers tend to fail due to the same characteristics that positively influenced their hiring decision.

BT - On the Inflationary Effects of Military Conflicts T2 - CEPA Discussion Papers N2 - Military conflicts and wars affect a country’s development in various dimensions. Rising inflation rates are a potentially important economic effect associated with conflict. High inflation can undermine investment, weigh on private consumption, and threaten macroeconomic stability. Furthermore, these effects are not necessarily restricted to the locality of the conflict, but can also spill over to other countries. Therefore, to understand how conflict affects the economy and to make a more comprehensive assessment of the costs of armed conflict, it is important to take inflationary effects into account. To disentangle the conflict-inflation-nexus and to quantify this relationship, we conduct a panel analysis for 175 countries over the period 1950–2019. To capture indirect inflationary effects, we construct a distance based spillover index. In general, the results of our analysis confirm a statistically significant positive direct association between conflicts and inflation rates. This finding is robust across various model specifications. Moreover, our results indicate that conflict induced inflation is not solely driven by increasing money supply. Furthermore, we document a statistically significant positive indirect association between conflicts and inflation rates in uninvolved countries.

BT - Distributional and climate impacts for Germany T2 - CEPA Discussion Papers N2 - The COVID-19 pandemic created the largest experiment in working from home. We study how persistent telework may change energy and transport consumption and costs in Germany to assess the distributional and environmental implications when working from home will stick. Based on data from the German Microcensus and available classifications of working-from-home feasibility for different occupations, we calculate the change in energy consumption and travel to work when 15% of employees work full time from home. Our findings suggest that telework translates into an annual increase in heating energy expenditure of 110 euros per worker and a decrease in transport expenditure of 840 euros per worker. All income groups would gain from telework but high-income workers gain twice as much as low-income workers. The value of time saving is between 1.3 and 6 times greater than the savings from reduced travel costs and almost 9 times higher for high-income workers than low-income workers. The direct effects on CO₂ emissions due to reduced car commuting amount to 4.5 millions tons of CO₂, representing around 3 percent of carbon emissions in the transport sector.

Rose-Ackerman [1973] postuliert, dass die Ringstruktur die Folge der Minimierung der Grenzlänge zwischen schwarzen und weißen Haushalten sei. Diese Annahme wird in der New-Urban-Economics-Literatur recht häufig übernommen. In diesem Beitrag wird auf der Grundlage eines Alonso-Mills-Muth-Modells gezeigt, dass Rose-Ackermans Hypothese nur in Situationen zulässig ist, in denen eine Gruppe deutlich in der Minderheit ist. In der Mehrheit der möglichen Verhältnisse der Gruppengrößen ist eine sektorale Stadtstruktur vorteilhaft. Werden anstelle der Grenzlängen die an der Grenze anfallenden negativen Externalitäten verglichen, nimmt der Bereich der Gruppengrößenverhältnisse, in denen die Sektorstruktur vorteilhaft ist, noch zu.

On the one hand, an inter-State law brutally regulating political relations between human groups whitewashed by nationalism; on the other hand, a transnational or “a-national” law regulating economic relations between private as well as public interests.

We find that density significantly increases pollution exposure. Looking only at urban areas, we find that population size affects exposure more than density. Moreover, the effect is driven mostly by population commuting to core cities rather than the core city population itself. We analyse heterogeneity by geography and income levels. By and large, the influence of population on pollution is greatest in Asia and middle-income countries. A counterfactual simulation shows that PM2.5 exposure would fall by up to 36% and NO2 exposure up to 53% if within countries population size were equalized across all cities.

The number of institutions involved in designing a competent response approach, com-bined with the unilateral and uncoordinated state reactions, have left unclear where to look for when searching for answers and new alternatives. Can the United Nations High Commissioner for Refugees (UNHCR) take a leading role in solving this and future crises? After a brief recapitulation of the crisis, an analysis of UNHCR’s statue, relationship to international law, and doctrine will put this question to the test while exploring options that are not only available but also feasible in a system where politics trump both legality and morality. If UNHCR is to play an active role in fu-ture refugee policies and become the lead agency it once was, a new daring and innovative approach has to emerge in order to readapt to the power relations that prevail in the twenty-first century.

N2 - Many European countries have experienced a significant increase of unemployment in recent years. This paper reviews several theoretical models that try to explain this phenomenon. Predominantly, these models claim a link between the poor performance of European labor markets and the high level of market regulation. Commonly referred to as the Eurosclerosis debate, prominent approaches consider insider-outsider relationships, search-models, and the influence of hiring and firing costs on equilibrium employment. The paper presents empirical evidence of each model and studies the relevance of the identified rigidities as a determinant of high unemployment in Europe. Furthermore, a case study analyzes the unemployment problem in Germany and critically discusses new reform efforts. In particular this section analyzes whether the recently enacted Hartz reforms can induce higher employment.

Bei einer gegebenen Punktwolke, die aus einem unbekannten topologischen Raum ausgewählt wurde, versucht die Topologische Datenanalyse (TDA) den ursprünglichen Raum zu rekonstruieren. Dieser Beitrag soll eine Einführung in die Topologische Datenanalyse geben und konzentriert sich dabei auf zwei wichtige Aspekte: die Persistente Homologie und den Mapper. Dabei werden zuerst die notwendigen theoretischen Grundlagen vorgestellt und anschließend wird die Methodik bei der Visualisierung von Daten eingesetzt. Die Persistente Homologie ist eines der Standardwerkzeuge in der TDA. Sie findet ihre Anwendung beispielsweise in den Bereichen Formerkennung und -beschreibung. Der Mapper als zweites wichtiges Konzept der TDA wandelt umfangreiche, höherdimensionale Datensätze in Simplizialkomplexe um und kann dadurch geometrische und topologische Eigenschaften der Daten bestimmen. Des Weiteren ist die Mapper-Methode ein brauchbares Werkzeug zur Visualisierungen von mehrdimensionalen Daten, woran statistische Verfahren scheitern. N2 - In the analysis of higher-dimensional data their shape can provide important information about the dataset. Given a point cloud sampled from an unknown topological space, topological data analysis tries to reconstruct the original space. This paper provides an introduction into topological data analysis (TDA) and focuses on two important aspects: Persistent Homology and Mapper. First, the theoretical basics are introduced and then the methodology is applied to visualize data. Persistent Homology represents a standard tools in the TDA. This approach is used, for example, in shape recognition and description. The Mapper is a second important concept of the TDA and converts wide, higher-dimensional datasets into simplicial complexes. By that it can determine geometric and topological properties of the data. Furthermore, the Mapper method is a useful tool for the visualization of multi-dimensional data, where statistical methods fail.

BT - The Effect of a Public Transport Subsidy on Air Quality T2 - CEPA Discussion Papers N2 - This paper provides novel evidence on the impact of public transport subsidies on air pollution. We obtain causal estimates by leveraging a unique policy intervention in Germany that temporarily reduced nationwide prices for regional public transport to a monthly flat rate price of 9 Euros. Us-ing DiD estimation strategies on air pollutant data, we show that this intervention causally reduced a benchmark air pollution index by more than six percent. Our results illustrate that public transport subsidies – especially in the context of spatially constrained cities – offer a viable alterna-tive for policymakers and city planers to improve air quality, which has been shown to crucially affect health outcomes.

Yet, appraisal varies regarding its extent and seriousness: Is it merely a rough time or are we standing on the edge of destruction? The article will trace developments inside as well as outside the WTO in order to assess the magnitude of the crisis. It will be argued that while certain developments inside the organisation, when seen in accumulation would already warrant serious attention, only together with developments taking place outside of the WTO, the two strands of developments unfold their full potential for the crisis. The overall situation renders the WTO in a difficult position, as it is currently unable to adapt to these challenges, while keeping calm and carrying on might similarly further the crisis. While States might improve and further develop their trade relations in bi- and plurilateral agreements, it is only the WTO that reflects and stands for the multilateral post (cold) war order.

Uniquely preponderant power enjoyed since the end of the Second World War has allowed US preferences to manifest not merely in specific rules and regimes, but in purposive development of the entire structure of global legal order to favour American security interests. Perceptions of a recent decline in this order now find expression in advocacy for a ‘liberal’ or ‘rules-based’ international order, as the claimed foundation for global prosperity and security. This working paper seeks to map out the parameters of US contributions to the global security order by uncovering the strategic and political foundations of its engagement with the international law of global security. The paper begins by reflecting on competing US conceptions of the relationship between national security and global order as they evolved across the twentieth century. The focus then turns to three significant trends defining the contemporary field. First are US attitudes toward multilateral institutions and global security, and the ongoing contest between beliefs that they are mutually reinforcing versus beliefs that US security and global institutions sit in zero-sum opposition. Second is the impact of the generational ‘War on Terror’, which has yielded more permissive interpretation and development of laws governing the global use of violence. The final trend is that towards competitive geopolitical interests restructuring international law, which are evident across diverse areas ranging from global economics, to cybersecurity, to the fragmentation of global order into spheres of influence. Looking ahead, a confluence of rising geopolitical competitors with divergent legal conceptions, and conflicted domestic support for the legitimacy and desirability of US global leadership, emerge as leading forces already reshaping the global security order.

This article questions their position. A vertical innovation model with a portfolio of technologies for abatement, adaptation, and general (Harrod-neutral) technology reveals that environmental damage spillovers have a comparable effect on research profits as technology spillovers so that the social costs of depleting public natural capital are internalized. As long as there is free access to information and technology, growth is sustainable and the allocation of research efforts among alternative technologies is socially optimal. While there still is a need to address externalities from monopolistic research markets, no environmental policy is necessary. These results suggest that environmental externalities may originate in restricted access to information and technology, demonstrating that (i) information has a similar effect as an environmental tax and (ii) knowledge and technology transfers have an impact comparable to that of subsidies for research in green technology.

This paper shows, through analysis of intergovernmental instruments, statements made by representatives of States, and negotiation records, that the rule of law at the United Nations has become increasingly contested in the past years. More precisely, the argument builds on the process of integrating the notion of the rule of law into the Sustainable Development Goals, adopted in September 2015 in the document Transforming our world: the 2030 Agenda for Sustainable Development. The main sections set out the background of the rule of law debate at the UN, the elements of the rule of law at the goal- and target-levels in the 2030 Agenda – especially in the SDG 16 –, and evaluate whether the rule of law in this context may be viewed as a normative and universal foundation of international law. The paper concludes, with reflections drawn from the process leading up to the 2030 Agenda and the final outcome document that the rule of law – or at least strong and precise formulations of the concept – may be in decline in institutional and normative settings. This can be perceived as symptomatic of a broader crisis of the international legal order.

We investigate how formal institutions, like product- and labor-market regulations, as well as the quality of regional governments that implement these regulations, affect HGF development across European regions. Using data from Eurostat, OECD, WEF, and Gothenburg University, we show that both regulatory stringency and the quality of the regional government influence the regional shares of HGFs. More importantly, we find that the effect of labor- and product-market regulations ultimately depends on the quality of regional governments: in regions with high quality of government, the share of HGFs is neither affected by the level of product market regulation, nor by more or less flexibility in hiring and firing practices. Our findings contribute to the debate on the effects of regulations by showing that regulations are not, per se, “good, bad, and ugly”, rather their impact depends on the efficiency of regional governments. Our paper offers important building blocks to develop tailored policy measures that may influence the development of HGFs in a region.

Both elements of CIL – practice and opinio juris – have assumed novel and broader forms, as noted in the Reports of the Special Rapporteur of the International Law Commission (2013, 2014, 2015, 2016). This paper discusses these Reports and the draft conclusions, and reaction by States in the Sixth Committee of the United Nations General Assembly (UNGA), highlighting the areas of consensus and contestation. This ties to the analysis of the main doctrinal positions, with special attention being given to the two elements of CIL, and the role of the UNGA resolutions. The underlying motivation is to assess the real or perceived crisis of CIL, and the author develops the broader argument maintaining that in order to retain unity within international law, the internal limits of CIL must be carefully asserted.

Human rights defenders have historically been defined on the basis of their actions as defenders. However, as Marxist-feminist scholar Silvia Federici contends, women are inherently politicised and, moreover, face obstacles to political action which are invisible to and untouchable by the law. Labour rights set an example of handling such a disadvantaged political position by placing vital importance on workers’ right to association and collective action. The paper closes with the suggestion that transposing this construction of rights to women would better protect women as human rights defenders while emphasising their capacity for self-determination in their political actions. N2 - Dieses Papier bewertet die Konstruktion der Rechte von Menschenrechtsverteidigern innerhalb des Völkerrechts und ihre Mängel beim Schutz von Frauen. Menschenrechtsverteidiger wurden in der Vergangenheit auf der Grundlage ihrer Tätigkeit als Verteidiger definiert. Wie die marxistisch-feministische Wissenschaftlerin Silvia Federici behauptet, sind Frauen jedoch von Natur aus politisiert und sehen sich darüber hinaus Hindernissen für politisches Handeln gegenüber, die für das Gesetz unsichtbar und unantastbar sind. Die Arbeitsrechte sind ein Beispiel für den Umgang mit einer derart benachteiligten politischen Position, indem sie dem Recht der Arbeitnehmer auf Vereinigungsfreiheit und kollektive Aktionen entscheidende Bedeutung beimessen. Das Papier schließt mit dem Vorschlag, dass die Übertragung dieser Rechtskonstruktion auf Frauen Frauen als Menschenrechtsverteidigerinnen besser schützen und gleichzeitig ihre Fähigkeit zur Selbstbestimmung in ihrem politischen Handeln betonen würde.

This productivity decline also holds true for professional services in other European countries. Using a German firm-level dataset of 700,000 observations between 2003 and 2017, we analyze this largely uncovered phenomenon among professional services, the 4th largest sector in the EU15 business economy, which provide important intermediate services for the rest of the economy. We show that changes in the value chain explain about half of the decline and the increase in part-time employment is a further minor part of the decline. In contrast to expectations, the entry of micro and small firms, despite their lower productivity levels, is not responsible for the decline. We also cannot confirm the conjecture that weakening competition allows unproductive firms to remain in the market.

T2 - KFG Working Paper Series N2 - This paper assesses, both quantitatively and qualitatively, the work of the Peace and Security Council (PSC) of the African Union (AU) with respect to peace support operations. It seeks to know whether the establishment of the PSC in 2002 is leading or has led to a rise or a decline of collective security in Africa. It is demonstrated that in regard to its relative legal and institutional robustness, the PSC can be perceived as a rise of collective security compared with its predecessor, the Central Organ of the Organisation of African Unity (OAU). However, it stagnates in terms of quantity and quality of actions on the ground. The main problem lies in the lack of sufficient operational autonomy from member states and international partners, such as the United Nations. Therefore, the PSC’s contribution to the maintenance of peace and security, and so the rise of the international rule of law in Africa is limited. The continent is still a war-torn region, affected by political crises and the expansion of terrorism in many countries. To solve this problem, AU member states should strengthen the PSC’s capacity, starting with the quick operationalisation of the African Standby Force. The implementation of the 2016 decision on alternative sources of financing AU’s institutions and activities is also a priority. In this regard, the political will of African states that may show that they want to take their organisation more seriously is required. This can further the AU self-reliance policy in collective security though the promotion of African solutions to African problems, and reduce the burden of the United Nations and other non-African actors’ interventions in the continent.

T1 - The Long-Run Effects of Sports Club Vouchers for Primary School Children T2 - CEPA Discussion Papers N2 - Starting in 2009, the German state of Saxony distributed sports club membership vouchers among all 33,000 third graders in the state. The policy’s objective was to encourage them to develop a long-term habit of exercising. In 2018, we carried out a large register-based survey among several cohorts in Saxony and two neighboring states. Our difference-in-differences estimations show that, even after a decade, awareness of the voucher program was significantly higher in the treatment group. We also find that youth received and redeemed the vouchers. However, we do not find significant short- or long-term effects on sports club membership, physical activity, overweightness, or motor skills.

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, who is properly incentivized to judge communication content and price setting behavior of the firms. Using this novel design, we revisit the question whether a leniency rule successfully destabilizes cartels. In contrast to existing experimental studies, we find that a leniency rule does not affect cartelization. We discuss potential explanations for this contrasting result.

The research project pursues the goal of determining whether public international law, as it has developed since the end of the Cold War, is continuing its progressive move towards a more human-rights- and multi-actor-oriented order, or whether we are seeing a renewed emphasis of more classical elements of international law. In this context the term “international rule of law” is chosen to designate the more recent and “thicker” understanding of international law. The paper discusses how it can be determined whether this form of international law continues to unfold, and whether we are witnessing challenges to this order which could give rise to more fundamental reassessments.

As the topics of the Commission are diverse, the outcome of its work is often seen as providing a sense of direction regarding general aspects of international law. After defining what he understands by “community interests”, the author looks at both secondary and primary rules of international law, as they have been articulated by the Commission, as well as their relevance for the recognition and implementation of community interests. The picture which emerges only partly fits the widespread narrative of “from self-interest to community interest”. Whereas the Commission has recognized, or developed, certain primary rules which more fully articulate community interests, it has been reluctant to reformulate secondary rules of international law, with the exception of jus cogens. The Commission has more recently rather insisted that the traditional State-consent-oriented secondary rules concerning the formation of customary international law and regarding the interpretation of treaties continue to be valid in the face of other actors and forms of action which push towards the recognition of more and thicker community interests.

We exploit regional variation in the promotion of mobility programs along administrative borders of German employment agency districts to investigate the causal effect of offering such financial incentives on the job search behavior and labor market integration of unemployed workers. We show that promoting mobility – as intended – causes job seekers to increase their search radius, apply for and accept distant jobs. At the same time, local job search is reduced with adverse consequences for reemployment and earnings. These unintended negative effects are provoked by spatial search frictions. Overall, the unconditional provision of mobility programs harms the welfare of unemployed job seekers.

In this context, we investigate whether the motives of becoming an entrepreneur influence the subsequent entrepreneurial development. In our analysis, we examine a broad range of business outcomes including survival and income, as well as job creation, expansion and innovation activities for up to 40 months after business formation. Using self-determination theory as conceptual background, we aggregate the start-up motives into a continuous motivational index. We show – based on a unique dataset of German start-ups from unemployment and non-unemployment – that the later business performance is better, the higher they score on this index. Effects are particularly strong for growth oriented outcomes like innovation and expansion activities. In a next step, we examine three underlying motivational categories that we term opportunity, career ambition, and necessity. We show that individuals driven by opportunity motives perform better in terms of innovation and business expansion activities, while career ambition is positively associated with survival, income, and the probability of hiring employees. All effects are robust to the inclusion of a large battery of covariates that are proven to be important determinants of entrepreneurial performance.

The following article deals with such challenges. Therefore it firstly defines the term of privacy in general and presents an international legal framework. With whisteblower Snowden a huge political discourse was initiated and the article gives insights into its further development. In 2015 the Human Rights Council for the first time announced a special rapporteur on the right to privacy. However, the discourse is not only taking place on a political level, also civil society organizations advocate more stringent regulations and prosecutions against violations of the right to privacy. Moreover the importance of the technology sector becomes clear. Companies like Microsoft are increasingly taking responsibility to protect digital media against unjustified data misuse, surveillance, collection and storage. But whereas the IT sector is developing very quickly, legislative processes do so rather slowly. Lastly, the individual is also hold to account. To protect oneself against data misuse is to a great extent acting self-responsible. Still, therefore information on protection must be clear and accessible for everyone. N2 - Das Recht auf Privatsphäre im digitalen Zeitalter stellt die internationale Gerichtsbarkeit vor neue Herausforderungen. Der nachfolgende Artikel beschäftigt sich mit diesen Herausforderungen. Er definiert „Privatsphäre“ und zeigt internationale rechtliche Rahmenbedingungen auf. Der seit Whisteblowern wie Snowden angestoßene internationale politische Diskurs und dessen Entwicklung werden beleuchtet. Der Menschenrechtsrat der Vereinten Nationen bestimmte im April 2015 erstmals einen Sonderberichterstatter für das Recht auf Privatsphäre. Jedoch findet der Diskurs nicht nur auf politischer Ebene statt: Auch zivilgesellschaftliche Organisationen setzten sich zunehmend für strengere Vorschriften und Strafverfolgungsmaßnahmen für Verstöße gegen das Recht auf Privatsphäre ein. Zudem wird auch die Bedeutung des IT-Bereichs deutlich. Technologieunternehmen wie Microsoft sehen sich zunehmend in der Verantwortung, digitale Medien gegen nicht gerechtfertigte Datenmissbrauch, Überwachungsmaßnahmen und Datensammlung zu schützen. Der IT-Bereich entwickelt sich sehr schnell – die Gesetzgebung hingegen sehr schleppend. Zuletzt wird auch die einzelne Person in Verantwortung gezogen. Sich selbst weit möglichst gegen Datenmissbrauch zu schützen, liegt bislang in der Hand des Einzelnen. Informationen zum Schutz müssen jedoch deutlich und zugänglich sein.

Whereas legal actors on the international level might normatively aim for law to have a similar effect to that of domestic law, the way in which international and supranational law can fulfil these potential functions is different. Accordingly, this paper argues that an awareness with regard to the particularities and challenges that the potential functions of law encounter in the international and supranational context is needed. Moreover, it suggests an analytical lens to conceptually frame and locate current developments, offering a broader perspective on, or even an element of explication for, the apparent crisis that law is currently facing on the international and supranational scale. After describing the potential functions of law on an abstract scale and grouping them into analytical categories, the paper uses these categories as a lens in order to assess in which way international law can fulfil these potential functions, where priorities regarding certain functions might differ and where some aspects of these functions are challenged when law is made and applied in the international and supranational sphere.

There is no evidence that treated students spend significantly more time, rather they tend to shift to more productive learning methods. The heterogeneity analysis suggests that higher treatment effects are associated with higher levels of behavioral bias but also with poor early course behavior.
