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.

Risky Asset Holdings during Covid-19 and Their Distributional Impact: Evidence from Germany

We present evidence from a repeated survey on risky asset holdings carried out on a representative sample of the German population six times between April and June 2020. Given the size of the Covid-19 shock, we find little evidence of portfolio rebalancing in April 2020. In May, however, individual investors started buying heavily, fueling market recovery. The cross-section shows large differences ...

The Productivity Puzzle in Business Services

In Germany, the productivity of professional services, a sector dominated by micro and small firms, declined by 40 percent between 1995 and 2014. 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 ...

What Drives Saudi Airstrikes in Yemen? An Empirical Analysis of the Dynamics of Coalition Airstrikes, Houthi Attacks, and the Oil Market

Since 2015, Saudi Arabia has led a foreign military intervention against the Houthi movement, which took over major parts of Yemen. The intervention, which manifests mainly in airstrikes, has attracted widespread controversy in media and politics as well as a large body of (qualitative) academic literature discussing its background and ways to escape it. Complementary to these efforts and connecting ...

Physician Effects in Antibiotic Prescribing: Evidence from Physician Exits

Human antibiotic consumption is considered the main driver of antibiotic resistance. Reducing human antibiotic consumption without compromising health care quality poses one of the most important global health policy challenges. A crucial condition for designing effective policies is to identify who drives antibiotic treatment decisions, physicians or patient demand. We measure the causal effect of ...

Culture, Children and Couple Gender Inequality

This paper examines how culture impacts within-couple gender inequality. Exploiting the setting of Germany's division and reunification, I compare child penalties of couples socialised in a more gender-egalitarian culture (East Germany) to those in a gender-traditional culture (West Germany). Using a household panel, I show that the long-run child penalty on the female income share is 26.9 percentage ...

The Multifaceted Impact of US Trade Policy on Financial Markets

We study the multifaceted effects and persistence of trade policy shocks on financial markets in a structural vector autoregression. The model is identified via event day heteroskedasticity. We find that restrictive US trade policy shocks affect US and international stock prices heterogeneously, but generally negatively, increasing market uncertainty, lowering interest rates, and leading to an appreciation ...

The Effect of Changing Marginal-Cost to Physical-Order Dispatch in the Power Sector

The analysis of local environmental policies is essential when evaluating the consistency of national public policies vis-à-vis the compliance of global agreements to reduce climate change. This study explores one of these policies; the 2021 Mexican reform to change electric power dispatch from a marginal-cost-based to a command and control physical system prioritizing power generation from the state ...

Disentangling Covid-19, Economic Mobility, and Containment Policy Shocks

We study the dynamic impact of Covid-19, economic mobility, and containment policy shocks. We use Bayesian panel structural vector autoregressions with daily data for 44 countries, identified through sign and zero restrictions. Incidence and mobility shocks raise cases and deaths significantly for two months. Restrictive policy shocks lower mobility immediately, cases after one week, and deaths after ...

Unconventional Fiscal Policy in HANK

In HANK, we show that fiscal policy is an appropriate macroeconomic stabilization tool at the ZLB. Fiscal policy achieves the same macroeconomic aggregates and the same welfare as hypothetically unconstrained monetary policy by replicating its transmission mechanism. Consumption taxes and labor taxes replicate the effects of monetary policy through the intertemporal substitution channel. Debt-financed ...

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 ...
