Local Fiscal Policies and Their Impact on the Number and Spatial Distribution of New Firms

We examine the effect of local business taxation and local public good and service (PIGS) provision on the number and spatial distribution of new firms. Testing ground is Germany and we rely on the universe of firm foundations between 1998 and 2006. Methodologically, we estimate fixed effects poisson models coupled with a control function approach. The results suggest that a 1%-decrease in the business ...

How Important Are Local Knowledge Spillovers of Public R&D and What Drives Them?

This paper analyzes the magnitude of local knowledge spillovers of public R&D in Germany and its determinants using patent application data. We identify three distinct transmission channels. First, firms file more patent applications when collaborating with (local) public institutions. Second, firms file more patent applications when citing a public patent. Third, local public R&D seems to increase ...

Dehydration Predicts Longitudinal Decline in Cognitive Functioning and Well-Being Among Older Adults

Adequate hydration is essential for health, with even mild forms of dehydration often having negative effects on cognition and well-being. Despite evidence of higher risk for dehydration among older adults, links between dehydration and cognitive or well-being outcomes have not been established in old age. In this study, we used longitudinal data from the Berlin Aging Study II (age range 60–89) to ...

An Auction Story: How Simple Bids Struggle with Uncertainty

Short-term electricity markets are key to an efficient production by generation units. We develop a two-period model to assess different bidding formats to determine for each bidding format the optimal bidding strategy of competitive generators facing price-uncertainty. We compare the results for simple bidding, block bidding and multi-part bidding. We find that even under optimal simple and block ...

Distributive Justice in Marriage: Experimental Evidence on Beliefs about Fair Savings Arrangements

Objective This study examines fairness perceptions of experimentally manipulated savings arrangements in couples (i.e., distribution of control and ownership of savings) to identify distributive justice principles in marriage.Background Theoretically, competing norms about individual ownership rights and autonomy (equity principle) and marital sharing (equality principle) in interaction with gender ...

Social Status Concerns and the Political Economy of Publicly Provided Private Goods

We analyse the political economy of the public provision of private goods when individuals care about their social status. Status concerns motivate richer individuals to vote for the public provision of goods they themselves buy in markets: a higher provision level attracts more individuals to the public sector, enhancing the social exclusivity of market purchases. Majority voting may lead to a public ...

Do Adult Men and Women in Same-Sex Relationships Have Weaker Ties to Their Parents?

Using a national sample of people in same-sex relationships (N = 843) and different-sex relationships (N = 510) in the Netherlands, we examine the frequently discussed but infrequently tested hypothesis of weaker intergenerational ties between parents and their adult daughters and sons in same-sex relationships. We also test hypotheses linking the strength of these ties to gender differences and the ...

What Determines the Elasticity of Substitution between Capital and Labor? A Literature Review

This paper provides the first comprehensive review of the empirical and theoretical literature on the determinants of the elasticity of substitution between capital and labor. Our focus is on the two-input constant elasticity of substitution (CES) production function. We start by presenting four concise observations that summarize the empirical literature on the estimation of σ. Motivated by these observations, ...

Pädagogische Konzeptionen von Kindertageseinrichtungen: Deskription eines pädagogischen Instruments

owohl die Praxisliteratur zum Einrichtungsmanagement als auch der Gesetzgeber sehen pädagogische Konzeptionen als ein probates Mittel zur Steuerung der Qualität von Kindertageseinrichtungen. Die vorliegende Studie untersuchte 583 Kita-Konzeptionen von Einrichtungen aus ganz Deutschland mithilfe eines neu entwickelten Codierschemas und quantitativen Analysemethoden. Im Zentrum stehen zwei Fragen: erstens ...

Using 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 ...

Modeling of Combined Heat and Power Generation in the Context of Increasing Renewable Energy Penetration

Combined heat and power (CHP) can achieve fuel efficiencies of up to 90% and is thus considered as economically advantageous and ecologically sound compared to uncoupled power and heat generation. This advantage is exploited only if CHP plants are operated as much as possible at their optimal operation point. Increasing penetration by variable renewable energy sources and more flexible technologies ...

Long-Term, Multicountry Perspective on Rental Market Regulations

This study introduces a new international longitudinal database of governmental rental market regulations. The regulations are measured using binary variables based on a thorough analysis of real-time, country-specific legislation. Three major restrictive policies are considered: rent control, protection from restriction, and housing rationing. The database covers 101 countries and states between 1910 ...

Where is the Consumer Center? A Case of St. Petersburg

In an urban economy, the distribution of people and real estate prices depends on the location of the central business district of a city. As distance from the city center increases, both prices and population density diminish, for travel costs increase in terms of time and money. As manufacturing gradually leaves the cities, the importance of consumer amenities as attractors of population to the urban ...

Time to Care? The Effects of Retirement on Informal Care Provision

This paper analyzes the impact of women's retirement on their informal care provision. Using SOEP data, we address fundamental endogeneity problems by exploiting variation in the German pension system in two complementary ways. We find a significant effect of retirement on informal care provision, when using early retirement age thresholds as instruments. Heterogeneity analyses confirm the underlying ...

Trajectories of Big Five Personality Traits: A Coordinated Analysis of 16 Longitudinal Samples

This study assessed change in self-reported Big Five personality traits. We conducted a coordinated inte-grative data analysis using data from 16 longitudinal samples, comprising a total sample of over 60 000 participants.We coordinated models across multiple datasets and fit identical multi-level growth models to assess and compare theextent of trait change over time. Quadratic change was assessed ...

In a Lonely Place: Investigating Regional Differences in Loneliness

Loneliness has traditionally been studied on the individual level. This study is one of the first to systematically describe and explaindifferences in loneliness on a fine-grained regional level. Using data from the nationally representative German Socio-EconomicPanel Study (N ¼17,602), we mapped the regional distribution of loneliness across Germany and examined whether regionaldifferences in loneliness ...

Coal Phase-out in Germany: Implications and Policies for Affected Regions

The present study examines the consequences of the planned coal phase-out in Germany according tovarious phase-out pathways that differ in the ordering of power plant closures. Soft-linking an energysystem model with an input-output model and a regional macroeconomic model simulates the socio-economic effects of the phase-out in the lignite regions, as well as in the rest of Germany. The combi-nation ...

Do Prices and Purchases Respond Similarly to Soft Drink Tax Increases and Cuts?

While in January 2012, Denmark increased the long-standing tax on sugary soft drinks, the tax was cut byhalf in July 2013 and then completely repealed in January 2014. In this study, we examine whetherincreases and cuts of the soft drink tax lead to similar over- or under-shifting to prices and to similardemand responses. We use longitudinal scanner data of 1,282 Danish households to estimate within-product ...

Transformational Strategies and Productivity Growth: A Transformational‐Activities Perspective on Stagnation in the New‐Normal Business Landscape

Declines in productivity growth substantially explain new‐normal business stagnation; yet in order to address situations of slack productivity growth, firms can choose from six generic transformational strategies: retirement, renewal, retrenchment, replication, redeployment, and recombination. While the extant literature focuses on specific transformational strategies that particular firms, or industries, ...
