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.

Border Carbon Adjustments and Alternative Measures for the EU ETS: An Evaluation

As part of its Green Deal, the European Commission is considering the introduction of border carbon adjustments and alternative measures. The measures, which would primarily apply to basic materials like steel and cement, pursue a double objective: they are aimed at enhancing the effectiveness of carbon pricing for the transition to climate neutrality but also at avoiding carbon leakage risks.

The Dynamic Impact of FX Interventions on Financial Markets

Evidence on the effectiveness of FX interventions is either limited to short horizons or hampered by debatable identification. We address these limitations by identifying a structural vector autoregressive model for the daily frequency with an external instrument. Generally, we find, for freely floating currencies, that FX intervention shocks significantly affect exchange rates and that this

Industrial Demand Response: How Network Tariffs and Regulation Do (Not) Impact Flexibility Provision in Electricity Markets and Reserves

Incentives for industrial loads to provide demand response on day-ahead and reserve markets are affected both by network tariffs, as well as regulations on the provision of flexibility in different markets. This paper uses a numerical model of the chlor-alkali process with a storable intermediate good to investigate how these factors affect the provision of demand response in these markets. We

Inequality over the Business Cycle – The Role of Distributive Shocks

This paper examines the dynamics of wealth and income inequality along the business cycle and assesses how they are related to fluctuations in the functional income distribution. In a panel estimation for OECD countries between 1970 and 2016 we find that on average income inequality - measured by the Gini coefficient - is countercyclical and also shows a significant association with the capital

Cost Efficiency and Endogenous Regulatory Choices: Evidence from the Transport Industry in France

We study the impact of different regulatory designs on the cost efficiency of operators providing a public service, exploiting data from the French transport industry. The distinctive feature of the study is that it considers regulatory regimes as endogenously determined choices, explained by economic, political, and institutional variables. Our approach leans on a positive analysis to study the

Coase and Cap-and-Trade: Evidence on the Independence Property from the European Electricity Sector

This paper provides an empirical test of the Coase Theorem. I analyze whether emissions are independent from allowance allocations in the electricity sector regulated under the EU's Emissions Trading System (EU ETS). Exogenous variation in levels of free allocation for power producing installations enables a difference-in-differences strategy. The analysis reveals that a change in al- location

Economic Effects of Transportation Infrastructure Quantity and Quality: A Study of German Counties

In this paper, we analyze the impact of transportation infrastructure quantity and quality on regional economic production. We exploit an extensive panel dataset on the German county level (N=401), expressing the capital value and condition of highways between 2007 and 2016, to estimate a spatially extended translog production function. The spatial specification uses SLX and SDEM models, with

Parental Leave Reform and Long-Run Earnings of Mothers

Paid parental leave schemes have been shown to increase women's employment rates but decrease their wages in case of extended leave durations. In view of these potential trade-offs, many countries are discussing the optimal design of parental leave policies. We analyze the impact of a major parental leave reform on mothers' long-term earnings. The 2007 German parental leave reform replaced a means

The Effects of Rent Control in Latin America: A Century of Regulations in Argentina

Following World War I, rent control became a standard policy response to the housing shortage and the resulting rent increases. Typically, economists blame it for creating inefficiencies in the housing market and beyond. We investigate whether rental market regulations (including rent control, protection of tenants from eviction, and housing rationing) had any effects in a middle-income Latin

Hours Risk and Wage Risk: Repercussions over the Life-Cycle

We decompose permanent earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks we formulate a life-cycle model of consumption and labor supply. Both permanent wage and hours shocks are important to explain earnings risk, but wage shocks have greater

Legal History, Institutions and Banking System Development in Africa

This paper links banking systems development to the colonial and legal history of African countries. Specifically, we investigate the impact of differing legal traditions on the development of existing investor and creditor protection, and on African banking systems. Based on a sample of 40 African countries from 2000 to 2016, our empirical findings show a significant dependence of current

Merger Efficiency Gains: Evidence from a Large Transport Merger in France

Many industries are seeing an increase in concentration, leading to a discussion on the effectiveness of horizontal merger enforcement. The policy debate shows that one of the key arguments put forward when supporting potential mergers is the possibility of realization of merger efficiency gains, specifically in the transport industry. Yet, there exists little empirical evidence on the actual

The MARS Algorithm in the Spatial Framework: Non-Linearities and Spatial Effects in Hedonic Models

Multivariate Adaptive Regression Spline (MARS) is a simple and powerful non-parametric technique that automatizes the selection of non-linear terms in regression models. Non-linearities and spatial effects are natural characteristics in numerous spatial hedonic pricing models. In this paper, we propose using the MARS data-driven methodology combined with the Instrumental Variables method in order

Is Monetary Policy Gender Neutral? Evidence from the Stock Market

We use US household survey data from 2001-2017 to investigate whether monetary policy has heterogeneous effects on women's and men's financial portfolio decisions by analyzing their equity investment. On the one hand, monetary policy significantly affects the entry decisions of women, but not of men: after a contractionary shock, the probability of women entering the stock market decreases. On the

The Role of Aggregators in Facilitating Industrial Demand Response: Evidence from Germany

Industrial demand response can play an important part in balancing the intermittent production from a growing share of renewable energies in electricity markets. This paper analyses the role of aggregators – intermediaries between participants and the electricity market – in facilitating industrial demand response. Based on the results from semi-structured interviews with German demand response

Does Social Policy through Rent Controls Inhibit New Construction? Some Answers from Long-Run Historical Evidence

The (re-)introduction of rent regulation in the form of rent controls, tenant protection or supply rationing is back on the agenda of policymakers in light of rent inflation in many global cities. While rent control as social policy promises short-term relief, economists point to their negative long-run effects on new construction. This paper present long-run data on both rent regulation and

Selection into Employment and the Gender Wage Gap across the Distribution and over Time

Using quantile regression methods, this paper analyses the gender wage gap across the wage distribution and over time (1990-2014), while controlling for changing sample selection into full-time employment. Our findings show that the selection-corrected gender wage gap is much larger than the one observed in the data, which is mainly due to large positive selection of women into fulltime employment

Energy Outlooks Compared: Global and Regional Insights

We compare prominent global energy scenarios of organisations and companies. We supplement the analysis with four own scenarios, which were derived from structured analytic techniques in combination with a numerical global energy and resource market model (Multimod). Our study provides three central contributions: (i) a compact survey of selected outlooks with meta characteristics (conceptual

Merger Policy in Digital Markets: An Ex-Post Assessment

This paper presents a broad retrospective evaluation of mergers and merger decisions in the digital sector. We first discuss the most crucial features of digital markets such as network effects, multi-sidedness, big data, and rapid innovation that create important challenges for competition policy. We show that these features have been key determinants of the theories of harm in major merger cases

The Effect of a Leniency Rule on Cartel Formation and Stability: Experiments with Open Communication

Cartels can severely harm social welfare. Competition authorities introduced leniency rules to destabilize existing cartels and hinder the formation of new ones. Empirically, it is difficult to judge the success of these measures because functioning cartels are unobservable. Existing experimental studies confirm that a leniency rule indeed reduces cartelization. We extend these studies by having a
