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.

I Am Innocent: Hourly Variations in Air Pollution and Crime Behavior

I posit that hourly changes in air pollution affect criminality through two distinct pathways, via physiological effects on the criminal and by changes in the tightness of the market for criminal activities. To disentangle individual from market effects, I develop a behavioral model of the individual decision to transgress and a model of search-and-matching frictions between criminals and crime opportunities. ...

Waiting for My Sentence: Air Pollution and the Productivity of Court Rulings

I assert that air pollution from nitrogen oxides affects the productivity of employees in Mexican court hearings. This is the first article analyzing this connection and the first to disentangle work-breaks from the productivity of white-collar workers. I merge hourly pollution with granular hearing data under the assumption that the length of the hearing approximates productivity and identify causality ...

Make Sure the Kids are OK: Indirect Effects of Ground-Level Ozone on Well-Being

This paper uses a panel of German individuals and highly granular pollution data to test if air pollution affects adults’ well-being indirectly through the health of their children. Results show that ozone decreases the well-being of individuals with children while not affecting persons without kids. We confirm the same effect for fine particulate matter and sulfur dioxide. Concerning the mechanism, ...

Heteroskedastic Proxy Vector Autoregressions

In proxy vector autoregressive models, the structural shocks of interest are identified by an instrument. Although heteroskedasticity is occasionally allowed for, it is typically taken for granted that the impact effects of the structural shocks are time-invariant despite the change in their variances. We develop a test for this implicit assumption and present evidence that the assumption of time-invariant ...

The Impact of Carbon Disclosure Mandates on Emissions and Financial Operating Performance

We examine whether a disclosure mandate for greenhouse gas emissions creates stakeholder pressure for firms to subsequently reduce their emissions. For UK-incorporated listed firms such a mandate was adopted in 2013. Using a difference-in-differences design, we find that firms affected by the mandate reduced their emissions – depending on the specification – by an incremental 14-18% relative to a control ...

Distributional Effects of the COVID-19 Lockdown

A two-sector incomplete markets model with heterogeneous agents can be used to study the distributional effects of the COVID-19 lockdown. While negative aggregate welfare effects of the lockdown are unavoidable, the size of aggregate welfare effects as well as the distribution of the welfare effects across agents turn out to depend on the specific economic environment of the affected economy as well ...

The Macroeconomic Effects of a European Deposit (Re-) Insurance Scheme

While the first two pillars of the European Banking Union have been implemented, a European deposit insurance scheme (EDIS) is still not in place. To facilitate its introduction, recent proposals argue in favor of a reinsurance scheme. In this paper, we use a regime-switching open-economy DSGE model with bank default and bank-government linkages to assess the relative efficiency of such a scheme. We ...

Active, or Passive? Revisiting the Role of Fiscal Policy in the Great Inflation

We reexamine whether pre-Volcker U.S. fiscal policy was active or passive. To do so, we estimate a DSGE model with monetary and fiscal policy interactions employing a sequential Monte Carlo algorithm (SMC) for posterior evaluation. Unlike existing studies, we do not have to treat each policy regime as distinct, separately estimated, models. Rather, SMC enables us to estimate the DSGE model over its entire ...

Structural Vector Autoregressive Models with more Shocks than Variables Identified via Heteroskedasticity

In conventional structural vector autoregressive (VAR) models it is assumed that there are at most as many structural shocks as there are variables in the model. It is pointed out that heteroskedasticity can be used to identify more shocks than variables. However, even if there is heteroskedasticity, the number of shocks that can be identified is limited. A number of results are provided that allow ...

Difference-in-Differences to Identify Causal Effects of COVID-19 Policies

Policymakers have implemented a wide range of non-pharmaceutical interventions to fight the spread of COVID-19. Variation in policies across jurisdictions and over time strongly suggests a difference-in-differences (DD) research design to estimate causal effects of counter-COVID measures. We discuss threats to the validity of these DD designs and make recommendations about how researchers can avoid ...

Institutional Diversity in Domestic Banking Sectors and Bank Stability: A Cross-Country Study

This paper analyzes the causal relationship between institutional diversity in domestic banking sectors and bank stability. We use a large bank- and country-level unbalanced panel data set covering the EU member states’ banking sectors between 1998 and 2014. Constructing two distinct indicators for measuring institutional diversity, we find that a high degree of institutional diversity in the domestic ...

Knowledge-Based Capital and Productivity Divergence

Understanding the causes of the slowdown in aggregate productivity growth is key to maintaining the competitiveness of advanced economies and ensuring long-term economic prosperity. This paper is the first to provide evidence that investment in Knowledge-Based Capital (KBC), despite having a positive effect on productivity at the micro level, is a driver of the weak productivity performance at the ...

Way Off: The Effect of Minimum Distance Regulation on the Deployment of Wind Power

Several countries and regions have introduced mandatory minimum distances of wind turbines to nearby residential areas, in order to increase public acceptance of wind power. Germany’s largest federal state Bavaria introduced such separation distances of ten times the height of new wind turbines in 2014. Here, we provide a novel monthly district-level dataset of construction permits for wind turbines ...

Currency Futures' Risk Premia and Risk Factors

The use of futures exchange contracts instead of forwards completes the maturity spectrum of the correlation between the spot yield and the premium. We find that the forward premium puzzle (FFP) depends significantly on the maturity horizon of the futures contract and the choice of sampling period. The FFP appears to be a pre-crisis phenomenon and is only observed for maturities longer than about one ...

Financial Education Affects Financial Knowledge and Downstream Behaviors

We study the rapidly growing literature on the causal effects of financial education programs in a meta-analysis of 76 randomized experiments with a total sample size of over 160,000 individuals. The evidence shows that financial education programs have, on average, positive causal treatment effects on financial knowledge and downstream financial behaviors. Treatment effects are economically meaningful ...

A Glimpse of Freedom: Allied Occupation and Political Resistance in East Germany

This paper studies costly political resistance in a non-democracy. When Nazi Germany surrendered in May 1945, 40% of the designated Soviet occupation zone was initially captured by the western Allied Expeditionary Force. This occupation was short-lived: Soviet forces took over after less than two months and installed an authoritarian regime in what became the German Democratic Republic (GDR). We exploit ...

Insolvency Regimes and Cross-Border Investment Decisions

This paper investigates the effect of reforms of insolvency regulations on cross-border debt and equity investments at a sectoral level. Using disaggregated data from the Securities Holdings Statistics by Sector (SHSS) and OECD-indicators on the efficiency of insolvency regulations, we find that investors prefer to invest more in countries with more efficient insolvency frameworks. The effect, however, ...

Viral Shocks to the World Economy

We construct a news-based viral disease index and study the dynamic impact of epidemics on the world economy, using structural vector autoregressions. Epidemic shocks have persistently negative effects, both directly and indirectly, on affected countries and on world output. The shocks lead to a significant fall in global trade, employment, and consumer prices for three quarters, and the losses are ...

The Financial Accelerator, Wages, and Optimal Monetary Policy

This paper studies the effects of labor market outcomes on firms’ loan demand and on credit intermediation. In a first step, I investigate how wages in the production sector affect bank net worth and the process of financial intermediation in partial equilibrium. Second, the role of the identified channels are studied in general equilibrium using a new- Keynesian DSGE-model with financial frictions and ...
