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.

Optimism Gone Bad? The Persistent Effects of Traumatic Experiences on Investment Decisions

Do memories of highly emotional stock market crashes permanently affect the investment decisions of households? The Initial Public Offerings of Deutsche Telekom during 1996- 2000 provide an optimal base to address this question, as it is known for its emotional character and is reputedly “the last time Germans invested in stocks.” Using Socio-Economic Panel (SOEP) household survey data, I show that ...

Cracking under Pressure? Gender Role Attitudes toward Maternal Employment in Times of a Pandemic

This paper studies the effects of Covid-19 related daycare and school closures on gender role attitudes toward maternal employment in Germany. We compare women and men with dependent children to those without children one year after the outbreak of the pandemic. Using data on gender role attitudes from 2008 through 2021, we find that fathers’ egalitarian attitudes toward maternal employment dropped ...

The Effect of Self-Control and Financial Literacy on Impulse Borrowing: Experimental Evidence

This paper examines the effect of reduced self-control on impulsive borrowing in a laboratory experiment. We manipulate self-control using an ego depletion task and show that it is effective. Following the ego depletion task, participants can anonymously buy hot drinks on credit. We find no significant average effects, but find that treated individuals that have low financial literacy are more likely ...

Comparison of Local Projection Estimators for Proxy Vector Autoregressions

Different local projection (LP) estimators for structural impulse responses of proxy vector autoregressions are reviewed and compared algebraically and with respect to their small sample suitability for inference. Conditions for numerical equivalence and similarities of some estimators are provided. A new LP type estimator is also proposed which is very easy to compute. Two generalized least squares ...

Climate Neutral Production, Free Allocation of Allowances under Emissions Trading Systems, and the WTO: How to Secure Compatibility with the ASCM

To reach climate neutrality, carbon emissions from the production of basic materials need to be significantly reduced. For governments’ support measures to be consistent with their World Trade Organization obligations, they need to be compatible with the WTO’s Agreement on Subsidies and Countervailing Measures (ASCM). This paper analyzes the ASCM consistency of three selected support schemes, namely: ...

Effectiveness, Spillovers, and Well-Being Effects of Driving Restriction Policies

We study the effectiveness, spillovers, and well-being effects of low emission zones in Germany, an emission-intensity-based driving restriction rapidly growing in popularity. Using regression discontinuity and group-time difference-in-differences designs, we show that previous estimates of the policy’s impact on traffic-related air pollution significantly underestimate its effectiveness. We provide ...

The Impact of Selection into the Labor Force on the Gender Wage Gap

We study the impact of selection bias on estimates of the gender pay gap, focusing on whether the gender pay gap has fallen since 1981. Previous research has found divergent results across techniques, identification strategies, data sets, and time periods. Using Michigan Panel Study of Income Dynamics data and a number of different identification strategies, we find robust evidence that, after controlling ...

Communications on Climate Change and Biodiversity Loss with Local Populations: Exploring Best-practices and Postcolonial Moments in Eight Case Studies from across the Globe

Climate change and biodiversity loss trigger policies worldwide, many of which target or impact local communities. Although research, international development, and policy implementation (and, thus, success in fighting both threats) require thoughtful consideration and communication of the underlying concepts, field work encounters a cascade of tangible barriers. Technoscientific representations of ...

Temporary VAT Reduction during the Lockdown

This paper evaluates the temporary VAT reduction introduced by the German government over the third and fourth quarter of 2020 as most controversial part of the COVID-19 stimulus package. Critics argue that VAT reductions are ineffective because of limited pass-through of temporary measures to consumer prices and in presence of lockdown measures. Advocates emphasize positive effects on durables and ...

Home Bias in Sovereign Exposure and the Probability of Bank Default - Evidence from EU Stress Test Data

Since the European debt crisis economists and politicians discuss intensively the sovereign-bank nexus. The high activity in sovereign bond issuance required to mitigate the burden of the Covid19 crisis will rather intensify this debate than calm it down. Surprisingly, however, we still have only limited knowledge about the impact of a home bias in sovereign exposure on bank stability. This paper provides ...

R&D Internationalization Strategies of the World’s Top Corporate R&D Investors

This paper contributes to the debate on the internationalization of the R&D activity of multinational enterprises (MNEs). Specifically, we examine the following research questions: (1) What are the determinants of the MNEs’ R&D internationalization level? (2) What types of internationalization strategies—home-base-augmenting (HBA), home-base-exploiting (HBE), technology-seeking (TS), and/or market-seeking ...

Employment Responses to Income Effect: Evidence from Pension Reform

For the design of the pension system, it is crucial to disentangle the employment responses related to the substitution effect and the income effect. In this paper, we provide causal evidence regarding the importance of the income effect, which is generally assumed to be small or non-existent. We exploit a pension reform in Germany that raised pension bene- fits related to children. For the identification, ...

Qualitative versus Quantitative External Information for Proxy Vector Autoregressive Analysis

A major challenge for proxy vector autoregressive analysis is the construction of a suitable external instrument variable or proxy for identifying a shock of interest. Some authors construct sophisticated proxies that account for the dating and size of the shock while other authors consider simpler versions that use only the dating and signs of particular shocks. It is shown that such qualitative (sign-)proxies ...

The Value of Data for Prediction Policy Problems: Evidence from Antibiotic Prescribing

Large-scale data show promise to provide efficiency gains through individualized risk predictions in many business and policy settings. Yet, assessments of the degree of data-enabled efficiency improvements remain scarce. We quantify the value of the availability of a variety of data combinations for tackling the policy problem of curbing antibiotic resistance, where the reduction of inefficient antibiotic ...

The Impact of ECB Corporate Sector Purchases on European Green Bonds

This papers analyzes the effect of the ECB’s Corporate Sector Purchase Programme (CSPP) and the recent Pandemic Emergency Purchase Programme (PEPP) on the yields of eligible green bonds, a new but rapidly growing segment of the corporate bond market. We exploit these policy changes using a difference-in-differences strategy, with ineligible corporate green bonds issued in euro, U.S. dollars and Swedish ...

Crowding of International Mutual Funds

We construct a fund-specific measure of crowding using the equity holdings overlap of 17,364 global funds which are actively managed. Funds in the top decile of crowding underperform the passive benchmark by 1.4% per year. The poor performance cannot be attributed to fees and transaction costs alone. When we explore the economics behind crowding, we establish that the diseconomies of crowding are distinct ...

Lender-Specific Mortgage Supply Shocks and Macroeconomic Performance in the United States

This paper provides evidence for the propagation of idiosyncratic mortgage supply shocks to the macroeconomy. Based on micro-level data from the Home Mortgage Disclosure Act for the 1990-2016 period, our results suggest that lender-specific mortgage supply shocks affect aggregate mortgage, house price, and employment dynamics at the regional level. The larger the idiosyncratic shocks to newly issued ...

Carbon Pricing of Basic Materials: Incentives and Risks for the Value Chain and Consumers

For the European Union to realise its ambition of carbon neutrality, emissions from basic material production need to be reduced through low-carbon production processes, material efficiency and substitution, as well as enhanced recycling. Different reform options for the EU ETS are discussed that ensure a consistent carbon price incentive for all these mitigation options, while avoiding the risk of ...

Two Dimensions of Political Trust in Russia

This paper analyzes two dimensions of factors of political trust in Russia. The first dimension is the target dimension (sociotropic vs. egocentric), the second dimension is the time dimension (retrospective vs. perspective). The study is based on the microdata of 2016 Life in Transition Survey (LiTS) of the European Bank for Reconstruction and Development. We find a robust evidence in favor of the ...

Measuring Unmeasurable: How to Map Laws to Numbers Using Leximetrics

As the institutional literature convincingly shows, socioeconomic phenomena are to a large extent shaped by the formal institutions, that is, legal acts (laws and ordinances). However, the latter are formulated in a specific language that is difficult to understand, let alone to measure. However, since the early 1990s, a whole branch of economic analysis of governmental regulations has evolved. It is ...
