This paper studies the dynamics between intra-household bargaining power and HIV prevention from a systemic perspective, using a panel data set of 500 married couples in rural Malawi from 2004-2008. All information has been matched at the couple level, which allows to directly assess the effect...

We study health care premium subsidies in the Swiss cantons in order to understand the reasons behind the substantial cross-cantonal variation in households' premium load, i.e., the share of disposable income that is spent on premiums after the subsidy. Cantons' financial situation is of...

Provided that the literature on th e deterrent effect of capital punishment is overall inconclu- sive, the fact that individual au thors persistently claim to have found solid evidence in one or the other direction raises two questions. Firstly, what are the causes for these different results?...

Provided that the literature on the deterrent effect of capital punishment is overall inconclusive, the fact that individual authors persistently claim to have found solid evidence in one or the other direction raises two questions. Firstly, what are the causes for these different results? Do...

We estimate a state-dependent multifactor model with two endogenous states. Its pricing accuracy is slightly superior to that of the Fama and French (1993, 1996) model. We have evidence for dramatically increased factor loadings for distress factors in one state. These results have implications...

Between 1991 and 1997 West Germany spent on average about 3.6 bn Euro per year on public sector sponsored training programmes for the unemployed. We base our empirical analysis on a new administrative data base that plausibly allows for selectivity correction by microeconometric matching...

This paper proposes sequential matching and inverse selection probability weighting to estimate dynamic casual effects. The sequential matching estimators extend simple, matching estimators based on propensity scores for static causal analysis that have been frequently applied in the evaluation...

After a short description of some positions which reject the principle of value freedom and after a short specification of what is meant with this principle, first the relation between the genesis of a scientific statement and its validity is discussed. There, we also tackle the problem of...

Customer markets are characterized by long-term relations between buyers and sellers. Long-term relations evolve if buyers trust sellers to provide high quality and if sellers are trustworthy. However, changes in the terms of this implicit contract may antagonize customers and disrupt the...

This paper examines the power of a conditional difference-in-differences approach to nonparametrically identify the causal effects of sequences of interventions. In the classical difference-in-differences case, a period previous to the implementation of the intervention is used as a comparison...
