Discussion Papers

About the Discussion Papers

The researchers at DIW Berlin usually publish their research results in scientific journals. However, this process can take many months, depending on the circumstances. To help bridge this gap, DIW Berlin began publishing Discussion Papers in 1989. The Discussion Papers offer a preview of the latest, not-yet-published research results, and allow current research to make its way into current debate more quickly.

Notes for authors

For publication in the series of DIW discussion papers the following may be submitted: Papers by DIW employees, DIW research professors and directors, DIW research affiliates and guest scientists who have spent at least one week at DIW Berlin and thank DIW Berlin in a footnote.    
Papers submitted will be sent in electronic form to the head of the relevant department at DIW Berlin. It is checked by an internal referee procedure whether or not the paper is likely to be published in a refereed journal. A decision on publication will then be made on the basis of a referee report. Should a paper have already been accepted for a publication by a refereed SSCI magazine or have received an invitation to a re-submission in a first-class journal, it will appear immediately without a referee procedure.

    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 ...

    Acquiring R&D Projects: Who, When, and What? Evidence from Antidiabetic Drug Development

    This paper analyzes M&A patterns of R&D projects in the antidiabetics industry. For this purpose, we construct a database with all corporate individual antidiabetics R&D projects over the period 1997 - 2017, and add detailed information on firms’ technology dimension using patent information, next to their position in product markets. This allows us to identify the identity of targets and acquirers ...

    The Macroeconomic Consequences of Import Tariffs and Trade Policy Uncertainty

    We estimate the macroeconomic effects of import tariffs and trade policy uncertainty in the United States, combining theory-consistent and narrative sign restrictions on Bayesian SVARs. We find mostly adverse consequences of protectionism. Tariff shocks are more important than trade policy uncertainty shocks. Tariff shocks depress trade, investment, and output persistently, in aggregate and across ...

    Buyer Power and the Effect of Vertical Integration on Innovation

    Our article investigates the impact of vertical integration (without foreclosure) on innovation. We compare cases where either (i) two manufacturers or (ii) a manufacturer and a vertically integrated retailer invest. Then, the independent manufacturer( s) and the retailer bargain over non-linear contracts before selling to consumers. We show that vertical integration always increases the incentives ...

    The Effect of Migration on Careers of Natives: Evidence from Long-term Care

    This paper examines the effect of increasing foreign staffing on the labor market outcomes of native workers in the German long-term care sector. Using administrative social security data covering the universe of long-term care workers and policy-induced exogenous variation, we find that increased foreign staffing reduces labor shortages but has diverging implications for the careers of native workers ...

    Realizing the Value of Recycling – Assessing the Elements of a Policy Package

    We investigate policies for increasing recycling to facilitate decarbonization within the basic material sector, including market-based policies, such as carbon pricing, advanced disposal fee and minimum recycled content requirement, and non-market policies, such as product design standard. We develop an analytical model to assess the role of these policy instruments for recycling related choices of ...
