Dieses Papier stellt Modellrechnungen zur Entwicklung der Gesetzlichen Rentenversicherung (GRV) vor. Es beruht vorwiegend auf dem MEA-PENSIM Modell des Munich Center of the Economics of Aging (MEA) und ergänzend auf dem PENPRO-Modell des DIW. Das Modell projiziert aus Annahmen und Setzungen in mehreren Schritten die Entwicklung der Demographie und Beschäftigung sowie der wichtigsten Kenngrößen der ...

DIW Discussion Papers 1856 / 2020
We show how policies to trigger clean technologies change price competition and market structure. We present evidence from electricity markets, where regulators have implemented different policies to subsidize clean energy. Building on a multi-unit auction model, we show that currently applied subsidy designs either foster or attenuate competition. Fixed, price-independent output subsidies decrease ...

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. When ...

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 impact ...

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 also ...

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 share. ...

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 determinants ...

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 levels ...

The superstar firms model provides a compelling explanation for two simultaneously occurring phenomena: the rise of concentration in industries and the fall of labor shares. Our empirical analysis confirms two of the underlying assumptions of the model: the market share increases and the labor share decreases with increasing firm-level total factor productivity, providing support for the superstar ...

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 various ...

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-tested ...

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 American ...

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 relevance. ...

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 financial ...

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 effects ...

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 to ...

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 ...

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 aggregators, ...

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 housing ...

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. ...
