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.

Heterogeneous Effects of After-School Care on Child Development

It is often argued that institutionalized after-school care (ASC) can benefit children lacking adequate homework support at home and, hence, foster equality of opportunity. However, despite considerable policy interest, it is unclear whether these afternoon programs are beneficial for child development and if selection into them is efficient, i.e., whether students benefiting most from the programs ...

Heteroskedastic Proxy Vector Autoregressions: Testing for Time-Varying Impulse Responses in the Presence of Multiple Proxies

We propose a test for time-varying impulse responses in heteroskedastic structural vector autoregressions that can be used when the shocks are identified by external proxy variables as a group. The test can be used even if the shocks are not identified individually. The asymptotic analysis is supported by small sample simulations which show good properties of the test. An investigation of the impact ...

Durable Consumption, Limited VAT Pass-Through and Stabilization Effects of Temporary VAT Changes

This paper revives the question of whether a temporary VAT change is an adequate instrument for crisis stabilization. In empirical assessments, we find that durable goods consumption fluctuates strongly over the business cycle and that VAT rate changes affect durable goods in particular. Therefore, we build a dynamic stochastic general equilibrium (DSGE) model that is capable of addressing this major ...

Stranded Assets in the Coal Export Industry? The Case of the Australian Galilee Basin

Steam coal exporters face increasing uncertainty about future coal demand and risks of asset stranding. Nevertheless, new export-oriented coal mine projects are still brought forward. In this study, we use the coal sector model COALMOD-World to assess the economic prospects of investments in the export-oriented steam coal sector, and in particular of coal mines in the Galilee Basin, Australia. We parameterize ...

Pandemic Depression: COVID-19 and the Mental Health of the Self-Employed

We investigate the effect of the COVID-19 pandemic on self-employed people’s mental health. Using representative longitudinal survey data from Germany, we reveal differential effects by gender: whereas self-employed women experienced a substantial deterioration in their mental health, self-employed men displayed no significant changes up to early 2021. Financial losses are important in explaining these ...

The Gender Gap in Lifetime Earnings: The Role of Parenthood

To obtain a more complete understanding of the persisting gender earnings gap in Germany, this paper investigates both the cross-sectional and biographical dimension of gender inequalities. Using an Oaxaca Blinder decomposition, we show that the gender gap in annual earnings is largely driven by women’s lower work experience and intensive margin of labor supply. Based on a dynamic microsimulation model, ...

How Communication Makes the Difference between a Cartel and Tacit Collusion: A Machine Learning Approach

This paper sheds new light on the role of communication for cartel formation. Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely ...

Forward to the Past: Short-Term Effects of the Rent Freeze in Berlin

In 2020, Berlin introduced a rigorous rent-control policy responding to soaring rents by setting a cap on rental prices: the Mietendeckel (rent freeze). The policy was revoked one year later by the German Constitutional Court. Although successful in reducing rents during its duration, the consequences for Berlin’s rental market and adjacent municipalities are not clear. In this paper we evaluate the ...

Facebook Shadow Profiles

Data is often at the core of digital products and services, especially when related to online advertising. This has made data protection and privacy a major policy concern. When surfing the web, consumers leave digital traces that can be used to build user profiles and infer preferences. We quantify the extent to which Facebook can track web behavior outside of their own platform. The network of engagement ...

Stimulating Housing Policy and Housing Tenure Choice: Evidence from the G7 Countries

Housing affordability is a hotly debated issue on global scale. A lack of affordable housing of decent quality is a chronic problem in urban areas. Governments try to alleviate it by stimulating homeownership among middle-income households and providing social housing for the low-income households. Such policies are very costly. Thus, this study aims to assess at least tentatively the effectiveness ...

The Effect of Social Comparison on Debt Taking: Experimental Evidence

A number of studies show that there is a link between social comparison and high levels of household debt. However, the exact mechanisms behind this link are not yet well understood. In this paper, we disentangle two mechanisms by performing a lab experiment designed to study the effects of social image concerns and peer information on consumption choices financed through debt taking. We find that ...

A Behavioral Heterogeneous Agent New Keynesian Model

We propose a behavioral heterogeneous agent New Keynesian model in which monetary policy is amplified through indirect general equilibrium effects, fiscal multipliers can be larger than one and which delivers empirically-realistic intertemporal marginal propensities to consume. Simultaneously, the model resolves the forward guidance puzzle, remains stable at the effective lower bound and determinate ...

House Price Expectations

This study examines short-, medium-, and long-run price expectations in housing markets. We derive and test six hypothesis about the incidence, formation, and relevance of price expectations. To do so, we use data from a tailored household survey, past sale and rental offerings, satellites, and from an information RCT. As novel findings, we show that price expectations exhibit mean reversion in the ...

Sovereign Bonds since Waterloo

This paper studies external sovereign bonds as an asset class. It compiles a new database of 266,000 monthly prices of foreign-currency government bonds traded in London and New York between 1815 (the Battle of Waterloo) and 2016, covering up to 91 countries. The main insight is that, as in equity markets, the returns on external sovereign bonds have been sufficiently high to compensate for risk. Real ...

Foreign Debt, Capital Controls, and Secondary Markets: Theory and Evidence from Nazi Germany

We investigate how internal distribution motives can interfere with the economic objectives of capital controls. In order to do this, we provide a model showing that elite capture can affect optimal debt repatriations and the management of official reserves under capital controls. Relying on these theoretical insights and a wealth of quantitative and qualitative historical evidence, we study one of ...

Income-Dependent Equivalence Scales and Choice Theory: Implications for Poverty Measurement

Equivalence Scales are a tool for removing the heterogeneity of household sizes in the measurement of inequality, and affect poverty assessments and poverty lines. We address the disadvantage that poor households may suffer due to their reduced ability to share goods within the household. This disadvantage is important to estimate and embed in standard analysis, as it seems to have a substantial quantitative ...

The Signalling Channel of Negative Interest Rates

Negative interest rates remain a controversial policy for central banks. We study a novel signalling channel and ask under what conditions negative rates should exist in an optimal policymaker’s toolkit. We prove two necessary conditions for the optimality of negative rates: a time-consistent policy setting and a preference for policy smoothing. These conditions allow negative rates to signal policy ...

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

With the expansion of onshore wind power, countries increasingly consider the introduction of minimum distance regulations between wind turbines to nearby residential areas, to increase public acceptance. In 2014, the German federal state of Bavaria introduced a minimum distance regulation that requires new wind turbines to be ten times their total height away from settlements (10-H regulation). This ...

Broadband and Productivity: Structural Estimates for Germany

We study the impact of broadband availability on firms’ total factor productivity (TFP) using German firm-level data between 2010 and 2015. We adopt a control function approach to causally identify and separately estimate productivity for 46 two-digit manufacturing and service sectors. Over the sample period, broadband availability, measured by 16 Mbps transmission rates, more than doubled in German ...

Competitors’ Reactions to Big Tech Acquisitions: Evidence from Mobile Apps

Since 2010, Google, Apple, Facebook, Amazon, and Microsoft (GAFAM) have acquired more than 400 companies. Competition authorities did not scrutinize most of these transactions and blocked none. This raised concerns that GAFAM acquisitions target potential competitors yet fly under the radar of current merger control due to the features of the digital economy. We empirically study the competitive effects ...
