Measuring Regional Inequality by Internet Car Price Advertisements: Evidence for Germany

We suggest to use car sale prices from internet advertisements for measuring economic inequality between and within German regions. Our estimates of regional income levels and Gini indices based on advertisements are highly positively correlated with the official figures.

Distributional Effects of the Child Tax Credit in Poland and Its Potential Reforms

Compliance with the Anti-trafficking Protocol

The Anti-trafficking Protocol reflects the interests of the major countries. Due to the high costs of compliance, countries will strategically select those obligations that will satisfy the major countries most efficiently with lower costs of compliance. Among the three main obligations of the Protocol - prevention, protection and prosecution - we predict that ratification leads to the strongest effect ...

Multi-family Households in a Labour Supply Model: A Calibration Method with Application to Poland

Models of cooperative and noncooperative behaviour opened the household "black box" and allowed for individual treatment of partners in couples. However, labour supply literature has so far largely ignored a broader issue - the distinction of single versus multi-family ("complex") households. We propose a method to account for multi-family household structure by borrowing from recent applications of ...

Assets, Shocks, and Poverty Traps in Rural Mozambique

This paper explores welfare dynamics among households in rural Mozambique. Using household panel data, we test whether an asset-based poverty trap exists. Findings indicate that all rural households converge to one stable equilibrium in the medium term, which is close to the poverty line. This may indicate that households in rural Mozambique are collectively trapped in generalized underdevelopment. ...

A Household Study of Self-Regulation in Children: Intergenerational Links and Maternal Antecedents

Delay of gratification (DoG) and delay discounting (DD) are behavioral measures of self-regulation and impulsivity. Whereas DoG refers to the postponement of gratification, DD involves the devaluation of a reward over time. Previous studies have demonstrated associations between paternal self-control, paternal personality traits, parenting styles, maternal intelligence, and children's self-regulation. ...

Naming and War in Modern Germany

This paper analyzes naming behavior in Germany in the context of rapid social change. It begins with an overview of general developments in naming in Germany over the last one hundred years, based on data from the German Socio-Economic Panel Study (SOEP), which supplies us with almost 45,000 datasets. The paper focuses on the periods of World War II and the Cold War since we conclude that general developments ...

Affective and Cardiovascular Responding to Unpleasant Events from Adolescence to Old Age: Complexity of Events Matters

Two studies investigated the overpowering hypothesis as a possible explanation for the currently inconclusive empirical picture on age differences in affective responding to unpleasant events. The overpowering hypothesis predicts that age differences in affective responding are particularly evident in highly resource-demanding situations that overtax older adults' capacities. In Study 1, we used a ...

Measuring Time Use in Surveys: Concordance of Survey and Experience Sampling Measures

It is still unclear to what extent time allocation retrospectively reported in questionnaires reflects people's actual behavior. Addressing this research gap, we analyze the congruence oftime use information assessed through retrospective questionnaires and through experience sampling methodology. Participants completed standard survey questions on time allocation. In addition, a mobile-phone-based ...

Respondent-Driven Sampling

Respondent-driven sampling is a network sampling technique typically employed for hard-to-reach populations (for example, drug users, men who have sex with men, people with HIV). Similarly to snowball sampling, initial seed respondents recruit additional respondents from their network of friends. The recruiting process repeats iteratively, thereby forming long referral chains. Unlike in snowball sampling, ...

Welfare-Related Health Inequality: Does the Choice of Measure Matter?

Using representative microdata from the German Socio-Economic Panel Study (SOEP), we show that the welfare measure choice has a substantial impact on the degree of welfare-related health inequality. To assess the sensitivity of welfare-related health inequality measures, we combine a unique set of income and wealth measures with different subjective, cardinalized, and (quasi-)objective health measures. ...

Investor Protection and the Value of Shares: Evidence from Statutory Rules Governing Variations of Shareholders' Class Rights in an Emerging Market

This article uses a quasi-experimental framework provided by recent changes in Russian corporate law to study the effect of investor protection on the value of shares. The legal change analyzed involves the empowerment of nonvoting shareholders to veto unfavorable changes to their class rights. We take advantage of the presence of well-defined treatment and control groups and use the voting premium, ...

Precautionary and Entrepreneurial Saving: New Evidence from German Households

Various studies interpret the positive correlation between income risk and wealth as evidence of significant precautionary savings. However, these high estimates emerge from pooling non-entrepreneurs and entrepreneurs, without controlling for heterogeneity. This article provides evidence for Germany based on representative panel data that includes private wealth balance sheets. Entrepreneurs, who face ...

Productivity and Financing of Regional Transport Infrastructure : Introduction

Mergers & Acquisitions and Innovation Performance in the Telecommunications Equipment Industry

The worldwide telecommunications equipment industry has experienced an enormous number of mergers and acquisitions (M&A). This article examines the innovation determinants of M&A activity and the consequences of M&A on technological potential and innovation performance. We extend the resource-based theory in elucidating external technology sourcing and provide empirical evidence on the keen reliance ...

Main Bank Power, Switching Costs, and Firm Performance: Theory and Evidence from Ukraine

We examine firms' motivation to change their main bank and how this switch affects loans, interest payments, and firm performance. Applying treatment effect analysis to unique firm-bank matched Ukrainian data, we find that larger and more highly leveraged companies are more likely to switch their main bank. Importantly, firms tend to switch to a new main bank that holds a higher share of equity in ...

The Threat Effect of Participation in Active Labor Market Programs on Job Search Behavior of Migrants in Germany

Purpose. Labor market programs may affect unemployed individuals' behavior before they enroll. The aim of this paper is to study whether such ex ante effects differ according to ethnic origin. Design/methodology/approach. The authors apply a method that relates self-reported perceived treatment rates and job search behavioral outcomes, such as the reservation wage or search intensity, to each other. ...

The IZA Evaluation Dataset: Towards Evidence-Based Labor Policy Making

Purpose. This paper aims to present the IZA Evaluation Dataset, a newly created data source allowing for the evaluation of active labor market policies in Germany. Design/methodology/approach. The paper's approach is a description of the sampling and contents of the IZA Evaluation Dataset and an outline of its research potential. Findings. The evaluation of active labor market policies is often confronted ...

Crude Oil Market Power: A Shift in Recent Years?

We investigate the exertion of market power in the global crude oil market over the past years. Recognizing the difficulty of identifying market power in the crude oil market by empirical studies, we propose a numerical partial equilibrium model formulated as a mixed complementarity problem. Our approach allows for strategic behavior in a Nash-Cournot market, a Stackelberg leader-follower game, an ...

The Complexity of Personality: Advantages of a Genetically Sensitive Multi-group Design

Findings from many behavioral genetic studies utilizing the classical twin design suggest that genetic and non-shared environmental effects play a significant role in human personality traits. This study focuses on the methodological advantages of extending the sampling frame to include multiple dyads of relatives. We investigated the sensitivity of heritability estimates to the inclusion of sibling ...
