How Does Retirement Affect Health? This paper investigates the effects of retirement on various health outcomes. Data stem from the first three waves of the English Longitudinal Study of Ageing (ELSA). With this informative data, non-parametric matching methods can be applied to identify causal effects. It is found that retirement significantly increases the risk of being diagnosed with a chron...

This paper estimates the effect of informal care provision on female caregiver’s health. We use data from the German Socio-economic Panel and assess effects up to seven years after care provision. A simulation-based sensitivity analysis scrutinizes the sensitivity of the results with respect to potential deviations from the conditional independence assumption in the regression adjusted matching...

Excess zeros are encountered in many empirical count data applications. We provide a new explanation of extra zeros, related to the underlying stochastic process that generates events. The process has two rates, a lower rate until the first event, and a higher one thereafter. We derive the corresponding distribution of the number of events during a fixed period and extend it to account for obse...

Rates of electronic information sharing and interoperability among hospitals remain low despite government investments exceeding $30 billion. Using a network economics framework, I show that low rates are driven by two factors. First, hospitals with weak market power avoid interoperability to keep patients from going elsewhere for care. Second, even if hospitals value interoperability, heteroge...

In this paper, we estimate a health care demand function for 18 OECD countries for the period 1972-1995. We consider a demand side approach where health expenditure depend on per capita GDP and the relative price of health care. We use panel data unit root and stationarity tests to characterize our data. Then, we test cointegration between our variables with Kao[16] panel data cointegration tes...

Self-selection can bias estimates of treatment effects from randomized experiments if one is interested not merely in the effect of treatment on the treated, but in extrapolating results to the general population. This paper employs the Roy model to study this problem in the context of medical trials. The main insight is that, as the probability of receiving active treatment rises, patients who...

Does union membership increase sickness absence from work and, if so, by how much? And which specific channels does this effect operate through? Using UK Labour Force Survey data for 2006-2008 we find that trade union membership is associated with a substantial increase in the probability of reporting sick and in the amount of average absence taken. This result can be largely attributed to the ...

The Effect of Breastfeeding on Children’s Cognitive and Noncognitive Development This paper uses propensity score matching methods to investigate the relationship between breastfeeding and children’s cognitive and noncognitive development. We find that breastfeeding for four weeks is positively and statistically significantly associated with higher cognitive test scores, by around one tenth of ...

Close to 30% of the US population experiences at least one mental or substance abuse disorder each year. Given the prevalence of mental health issues, this paper analyzes the role of mental health and cognitive functioning in household portfolio choice decisions. Generally, we find that households affected by mental health issues decrease investments in risky instruments. Various mental health ...
