Diskussionspapiere

Redaktion und HerausgeberInnen

Die WissenschaftlerInnen des DIW Berlin veröffentlichen ihre Forschungsergebnisse üblicherweise in Fachzeitschriften. Dieser Prozess kann unter Umständen mehrere Monate dauern - deshalb gibt das DIW Berlin seit 1989 die Diskussionspapiere heraus, in denen wir die Forschungsergebnisse vorab veröffentlichen. So gelangen aktuelle Forschungsergebnisse auch in die aktuelle Diskussion.

Hinweise für AutorInnen

Zur Veröffentlichung in der Reihe der DIW-Diskussionspapiere eingereicht werden können: Papiere von DIW-MitarbeiterInnen, DIW-ForschungsdirektorInnen, DIW-Research Affiliates und GastwissenschaftlerInnen, die mindestens eine Woche am DIW Berlin verbracht haben und in der Dankesfußnote dem DIW Berlin danken.
Das eingereichte Papier wird dem/der zuständigen AbteilungsleiterIn im DIW Berlin in elektronischer Form zugeschickt. Durch ein internes Referee-Verfahren wird geprüft, ob das Papier sehr gute Chancen für eine Veröffentlichung in einer referierten Zeitschrift hat. Auf der Basis eines Refereereports wird dann über die Veröffentlichung entschieden. Hat ein Papier bereits eine Veröffentlichungszusage einer referierten SSCI-Zeitschrift oder eine Einladung zu einer Re-Submission in einem sehr guten Journal, erscheint das Papier sofort ohne ein Referee-Verfahren.

    Enabling Circular Economy Dynamics in the Plastics and Steel Industries: Perspectives from Multiple Stakeholders

    This paper investigates the perspectives of stakeholder groups in the plastic and steel value chains on transitioning toward a circular economy (CE). Through semistructured interviews with 31 business stakeholders, we analyze business strategies, key factors, challenges and opportunities, as well as coordination and regulatory needs for a successful industry-wide CE transition. Our findings highlight ...

    Cream-skimming through PPAs – Interactions between Private and Public Long-term Contracts for Renewable Energy

    Public support systems and private investments in renewable energy are increasingly existing side-by-side and are both emphasized in policy proposals on the European and national levels. This paper assesses the interaction between the two approaches with respect to cream-skimming, i.e., the potential for low-cost projects to sign private contracts that increase the costs of publicly supported renewable ...

    Returns to Data: Evidence from Web Tracking

    Tracking online user behavior is essential for targeted advertising and is at the heart of the business model of major online platforms. We analyze tracker-specific web browsing data to show how the prediction quality of consumer profiles varies with data size and scope. We find decreasing returns to the number of observed users and tracked websites. However, prediction quality increases considerably ...

    The Evolution of Theories of Harm in EU Merger Control

    We discuss the main Theories of Harm in EU merger control and their evolution since the 1990s. We present stylised facts and trends using data extracted from EU merger decisions by natural language processing tools. EU merger policy has adapted over time, both in terms of legislation and theories of harm, as well as in terms of the investigative tools and evidence used. The introduction of the new ...

    Friend, Not Foe - Energy Prices and European Monetary Policy

    This paper first shows that, contrary to conventional wisdom, the European Central Bank (ECB) can influence global energy prices. Second, through Lucas critique-robust counterfactual analysis, we uncover that the ECB’s ability to affect fast-moving energy prices plays an important role in the transmission of monetary policy. Third, we empirically document that, to optimally fulfill its primary mandate, ...

    Merger Remedies and Bargaining Power in the Coffee Market

    This paper analyzes a merger of large manufacturers with divestiture in the French coffee market. In contrast to previous approaches used to study the effects of upstream divestitures on prices and welfare, we model the vertical market structure. First, our results show that the standard policy recommendation to require divestiture to small recipient firms may not hold when asymmetric bargaining power ...

    Advertising in Online Labor Markets: A Signal of Freelancer Quality?

    Freelancers face cold-start problems in online labor markets: getting hired is very difficult without ratings, while obtaining a rating is impossible unless already having been hired. According to economic theory and empirical evidence, advertising can serve as a signal of product quality for experience goods. As such, advertising might help skilled new freelancers without reputation on a platform ...

    Spatial Competition and Pass-through of Fuel Taxes: Evidence from a Quasi-natural Experiment in Germany

    This paper analyses the pass-through rates and their determinants of the temporary German fuel discount in 2022 at its start and its termination. Based on a unique dataset of fuel station characteristics and prices, we employ a Regression Discontinuity in Time (RDiT) methodology to estimate heterogeneous pass-through rates. Our main contribution is to identify the impact of horizontal and vertical ...

    Renminbi Rising? Exporters' Response to China's Currency Internationalization

    This paper investigates the heterogeneous responses of exporters to policy reforms undertaken by the People’s Bank of China to internationalize the Renminbi (RMB). Using detailed customs data from France for the initial years of these reforms (2011-2017), it documents several novel stylized facts on RMB adoption, highlighting both the growth and extreme skewness in RMB’s uptake across firms and varieties. ...

    Is There an Information Channel of Monetary Policy?

    Exploiting the heteroscedasticity of the changes in short-term and long-term interest rates and exchange rates around the FOMC announcement, we identify three structural monetary policy shocks. We eliminate the predictable part of the shocks and study their effects on financial variables and macro variables. The first shock resembles a conventional monetary policy shock, and the second resembles an ...

    Sustainable Finance Taxonomies: Enabling the Transition towards Net Zero? A Transition Score for International Frameworks

    A plethora of sustainable finance taxonomies are emerging worldwide to support shifting trillions for climate action. Employing a qualitative research approach, we use document analysis to assess 26 sustainable finance taxonomy frameworks worldwide that are in the developing phase or have been published and/or adopted. Based on literature and data we build a transition score (TS) to evaluate the framework’s ...

    Revisiting Investment Costs for Green Steel: Capital Expenditures, Firm Level Impacts, and Policy Implications

    The transition of the steel sector to carbon neutrality requires significant investment. In this study, we aim to better understand the scale of investment required for a transition to hydrogen-based steelmaking and the ability of listed steelmakers to finance this investment. First, we analyze how capital expenditures are estimated in the academic literature and compare them with reported investment ...

    Partial Identification of Heteroskedastic Structural VARs: Theory and Bayesian Inference

    We consider structural vector autoregressions identified through stochastic volatility. Our focus is on whether a particular structural shock is identified by heteroskedasticity without the need to impose any sign or exclusion restrictions. Three contributions emerge from our exercise: (i) a set of conditions under which the matrix containing structural parameters is partially or globally unique; (ii) ...

    Bad Luck or Bad Decisions? Macroeconomic Implications of Persistent Heterogeneity in Cognitive Skills and Overconfidence

    Business cycle models often abstract from persistent household heterogeneity, despite its potentially significant implications for macroeconomic fluctuations and policy. We show empirically that the likelihood of being persistently financially constrained decreases with cognitive skills and increases with overconfidence thereon. Guided by this and other micro evidence, we add persistent heterogeneity ...

    Does Gender of Firm Ownership Matter? Female Entrepreneurs and the Gender Pay Gap

    We examine how the gender of business-owners is related to the wages paid to female relative to male employees working in their firms. Using Finnish register data and employing firm fixed effects, we find that the gender pay gap is – starting from a gender pay gap of 11 to 12 percent - two to three percentage-points lower for hourly wages in female-owned firms than in maleowned firms. Results are robust ...

    Determinants of Stock Market Participation

    The low degree of stock market participation (SMP) is one of the big puzzles in finance. Numerous determinants have been proposed. We put these determinants into a structure that is derived from a standard static portfolio model. Then we discuss arguments put forward regarding specific SMP determinants and the empirical evidence that has been provided. The focus of our survey is on the identification ...

    New Trade Models, Same Old Emissions?

    This paper investigates the elusive role of productivity heterogeneity in new trade models in the trade and environment nexus. We contrast the Eaton-Kortum and the Melitz models with firm heterogeneity to the Armington and Krugman models without heterogeneity. We show that if firms have a constant emission share in terms of sales — as they do in a wide range of trade and environment models — the three ...

    The Women in Economics Index - Monitoring Women Economists' Representation in Leadership Positions

    We contribute to the research on gender representation in economics by documenting the share of women among economists in a variety of leadership positions in the academic, but also in the private and public sectors, both globally and by region. For the years 2019 to 2023, we find women economists’ representation overall to be low in all sectors and no clear-cut trends over time. In academia, we find ...

    Financial Repression in General Equilibrium: The Case of the United States, 1948–1974

    Financial repression lowers the return on government debt and contributes, all else equal, towards its liquidation. However, its full effect on the debt-to-GDP ratio hinges on how repression impacts the economy at large because it alters investment and saving decisions. We develop and estimate a New Keynesian model with financial repression. Based on U.S. data for the period 1948–1974, we find, consistent ...

    Persistent US Current Account Deficit: The Role of Foreign Direct Investment

    This paper re-evaluates the US external deficit which has considerably widened over the 1990s. US safe asset provision to the rest of the world is the dominant explanation for the persistent nature of the US external deficit. We suggest that apart from the safe asset hypothesis, there is an important role for technology shocks originating in US multinational companies that have a strong foreign direct ...
