Social distancing is important to slow the community spread of infectious disease, but it creates enormous economic and social cost. Thus, it is important to quantify the benefits of different measures. We study the ban of mass gatherings, an intervention with comparably low cost. We exploit exogenous variation in the number of National Basketball...

To address the opioid crisis, it is crucial to understand its origins. We provide descriptive evidence for the intergenerational persistence of opioid dependence. Our analysis is based on administrative data covering the universe of Austrian births from 1984 to 1990. We consider prescription opioids and a new proxy for addiction to illicit opioids....

We study the effectiveness of intrahousehold insurance among married couples when the husband loses his job due to a mass layoff or plant closure. Empirical results based on Austrian administrative data show that husbands suffer persistent employment and earnings losses, while wives’ labor supply increases moderately due to extensive margin respons...

Despite the growing incidence of cesarean deliveries (CDs), procedure costs and benefits continue to be controversially discussed. In this study, we identify the effects of CDs on subsequent fertility and maternal labor supply by exploiting the fact that obstetricians are less likely to undertake CDs on weekends and public holidays and have a great...

Does tax evasion run in the family? To answer this question, we study the case of the commuter tax allowance in Austria. This allowance is designed as a step function of the distance between the residence and the workplace, creating sharp discontinuities at each bracket threshold. It turns out that the distance to the next higher bracket is a stron...

Does the presence of immigrants in one's neighborhood affect voting for far right-wing parties? We study the case of the Freedom Party of Austria (FPÖ) that, under the leadership of Jörg Haider, increased its vote share from less than 5% in the early 1980s to 27% by the end of the 1990s and continued to attract more than 20% of voters in the 2013 n...

Early intervention is considered the optimal response to developmental disorders in children. We evaluate a nationwide developmental screening program for preschoolers in Austria and the resulting interventions. Identification of treatment effects is determined by a birthday cutoff-based discontinuity in the eligibility for a financial incentive to...

We study the effect of the size of the welfare state on family outcomes in OECD member countries. Exploiting exogenous variation in public social spending, due to varying degrees of political fractionalization (i.e. the number of relevant parties involved in the legislative process), we show that an expansion in the welfare state increases the fert...

Policies to promote marriage are controversial, and it is unclear whether they are successful. To analyze such policies, it is essential to distinguish between a marriage that is created by a marriage-promoting policy (marginal marriage) and a marriage that would have been formed even in the absence of a state intervention (average marriage). In th...

Using a matched insurant-general practitioner panel data set, we estimated the effect of a general health-screening program on individuals' health status and health care cost. To account for selection into treatment, we used regional variations in the intensity of exposure to supply-determined screening recommendations as an instrumental variable....

Extreme-right-wing (ERW) parties are on the rise in many countries. Moreover, there is an alarmingly high cross-country correlation between the election success of ERW parties and immigration. Motivated by this evidence, we explore one potentially important channel through which immigration may drive support for ERW parties: the presence of immigra...

This paper documents that changes in assortative mating patterns over the last four decades along the dimensions of age, ethnicity, religion and education are not responsible for the increasing marital instability. Quite the contrary, without the rise in the age at marriage, divorce rates would be considerably higher. Immigration and secularization...

Since the 1970s almost all US states have introduced a form of joint custody after divorce. I analyze the causal effect of these custody law reforms on different family outcomes. My identification strategy exploits the different timing of reforms across the US states. Estimations based on state panel data suggest that the introduction of joint cust...

This paper explores one potentially important channel through which immigration may drive support for extreme right-wing parties: the presence of immigrants in one's neighborhood. We study the case of the Freedom Party of Austria (FPÖ). Under the leadership of Jörg Haider, this party increased its share of votes from less than 5 percent in the earl...

We examine the effect of joint custody on marriage, divorce, fertility and female employment in Austria using individual-level administrative data, covering the entire population. We also use unique data obtained from court records to analyze the effect on post-divorce outcomes. Our estimates show that joint custody significantly reduces divorce an...

This paper interprets accidents occurring on the way to and from work as negative health shocks to identify the causal effect of health on labor market outcomes. We argue that in our sample of exactly matched treated and control workers, these health shocks are quasi-randomly assigned. A fixed-effects difference-in-differences approach estimates a...

Policies to promote marriage are controversial. It is essential to distinguish between a marriage which is created by a marriage promoting policy (marginal marriage), and a marriage which would have been formed even in the absence of a state interven-tion (average marriage). In this paper we exploit the suspension of a cash-on hand marriage subsidy...

We experimentally investigate social effects in a principal-agent setting with incomplete contracts. The strategic interaction scheme is based on the well-known Investment Game (Berg et al., 1995). In our setting four agents (i.e., trustees) and one principal (i.e., trustor) are interacting and the access to choices of peers in the group of trustee...

Does the supply of a welfare state create its own demand? Many economic scholars studying welfare arrangements refer to Say's law and insinuate a self-destructive welfare state. However, little is known about the empirical validity of these assumptions and hypotheses. We study the dynamic effect of different welfare arrangements on benefit fraud. I...

This paper explores the capability of the state to affect the individual's decision to work for free. For this purpose we combine individual-level data from the European and World Values Survey with macroeconomic and political variables for OECD member countries. Empirically we identify three channels for crowding out of voluntary labor. Firstly, a...

If participation in the labour market helps to secure women's outside options in the case of divorce/separation, an increase in the perceived risk of marital dissolution may accelerate the increase in female labour supply. This simple prediction has been tested in the literature using time and/or spatial variation in divorce legislation (e.g., acro...

In this note we model the individual decision on income underreporting in a system with a negative income tax. We show that a change in the tax rate has opposing effects on the compliance behavior of the poor and the rich.

This paper analyses how institutional factors affect satisfaction with democracy (SWD). It employs a panel of observations from Eurobarometers in the time span 1990-2000, and thus is one of the first studies to consider the longitudinal dimension of the driving forces of SWD. We find that high-quality institutions like the rule of law, well-functio...

Whether a country is able effectively to address collective action problems is a critical test of its ability to fulfill the demands of its citizens to their satisfaction. We study one particularly important collective action problem: the environment. Using a large panel dataset covering 25 years for some countries, we find that, overall, citizens...

While there is an extensive literature on tax evasion a further aspect of cheating on the state, namely benefit fraud, has gained relatively modest attention in the economic literature. This paper seeks to fill this gap. We explore differences between benefit fraud and tax evasion due to differing social norms. We define the concepts of benefit mor...

The ultimate aim of the EU Savings Tax Directive is the effective taxation of interest income. The EU has switched with the Directive from a policy which was based on trust in the citizens and on a certain degree of self-determination, to a procedure which is characterized by distrust and monitoring. On the other hand the Directive's regulations wh...

We present a model where divorcing spouses can choose to hire lawyers in their divorce process. Spouses encounter incentives as in the classical prisoners’ dilemma: Despite the zero sum nature of the game and the lawyers’ fees, each spouse has an incentive to hire a lawyer. We propose a simple institutional setting allowing for joint lawyers in ord...

This paper explores individual motives for volunteering. The analysis is based on the interpretation of volunteering as a consumption good (consumption model) or as a mean to increase individual's own human capital (investment model). We present an econometric framework taking into account self selection into volunteering and simultaneity between t...

We analyse local compensation payments made to farmers for providing landscape amenities in Alpine tourist communities. These payments result from political bargaining at the municipal level. Panel data estimation shows that the probability of introducing compensation payments depends positively on the benefits of landscape amenities. Although no i...

We model the bargaining process of parents over custody at the time of divorce. First we assume an institutional setting where only sole custody is available. In a second step we reform this institutional setting and introduce the possibility of joint custody. We show that some parents, who would not be able to find an agreement in a sole custody r...

This paper deals with a cross section analysis of local compensation payments to farmers for their provision of landscape amenities in alpine tourist communities. These payments can be interpreted as the outcomes of Coasian negotiations. Based on Austrian data we empirically identify the underlying determinants of the negotiating process. The proba...

Our analysis shows that the resident parent receives more alimony and the child more maintenance, if the resident parent hired a lawyer to present the case in court. Using propensity score matching techniques, we show that the financial benefit of hiring a lawyer is statistically significant and substantial. The estimates suggest a causal effect of...

Im Jahr 2003 wurden 88,4% aller Scheidungen in Oesterreich im Einvernehmen geschieden. Die einvernehmliche Scheidung erfordert - wenn beide Gatten die Scheidung wuenschen - nur eine Vereinbarung der wesentlichen Scheidungsfolgen. Anhand von Scheidungsakten der Jahre 1997-2003 eines oesterreichischen Bezirksgerichtes werden diese Scheidungsvereinbar...
