Mixed equilibrium in a pure location game: the case of n ≥ 4 firms

The Hotelling game of pure location allows interpretations in spatial competition, political theory, and professional forecasting. In this paper, the doubly symmetric mixed-strategy equilibrium for n ≥ 4 firms is characterized as the solution of a well-behaved boundary value problem. The analysis suggests that, in contrast to the cases n = 3 and n → ∞ , the equilibrium for a finite…

Higher bank capital requirements and mortgage pricing: evidence from the Counter-Cyclical Capital Buffer

We examine mortgage pricing before and after Switzerland was the first country to activate the Counter-Cyclical Capital Buffer of Basel III. Observing multiple mortgage offers per request, we obtain three core findings. First, capitalconstrained and mortgage-specialized banks raise their rates relatively more. Second, risk-weighting schemes supposed to discriminate against more risky…

Standardised packaging and tobacco-industry-funded research

We recently assessed the (possible) effect of plain packaging on the smoking behaviour of young Australian individuals (aged 14–17 years). Our conclusion was that there is no evidence that plain packaging has lowered smoking prevalence among young Australians.

The tempest: Natural disasters, Early Shocks and Children's Short- and Long-Run Development

Socio-economic shocks during early childhood are predicted to have detrimental short- and long-run consequences for children's development. We examine this hypothesis using a specific shock: housing damages caused by a super-typhoon. Comparing children, who lived in the same district, but only some experienced housing damages, we can isolate the real-estate shock from any…

Wealth shocks and health outcomes: evidence from stock market fluctuations

Do wealth shocks affect the health of the elderly in developed countries? The economic literature is skeptical about such effects which have so far only been found for poor retirees in poor countries. In this paper I show that wealth shocks also matter for the health of wealthy retirees in the US. I exploit the booms and busts in the US stock market as a natural experiment that…

Exploiting and exploring the options

In an ever-changing world, the brain must continually formulate, monitor, and adapt patterns of behavior to achieve the best outcome. Often, strategies that we have employed in the past to solve a problem or reach a specific result will work again when we are confronted with a similar situation. When this is the case, we can exploit such strategies for maximal gain. However, if…

Financial support from the family network and illegal immigration

Barriers to immigration of low-skilled workers from developing countries into the advanced countries prevent many potential migrants from leaving their countries of origin. With very low home-country wages in relation to the cost of undocumented migration, the opportunity to migrate often hinges on becoming indebted to a human smuggling organization or family and friends. This paper…

Combining Matching and Nonparametric Instrumental Variable estimation: Theory and an Application to the Evaluation of Active Labour Market Policies : Appendix

We show how instrumental variable and matching estimators can be combined in order to identify a broader array of treatment effects. Instrumental variable (IV) estimators are known to estimate effects only for the compliers, representing a subset of the entire population. By combining IV with matching, we can estimate the treatment effects for the always- and never-takers as well.…

This paper uses detailed information on the latitude and longitude of conflict events in Sub-Saharan African countries to study the impact of external income shocks on the likelihood of violence. We consider a number of external demand shocks faced by the countries or the regions within countries - temporary shocks such as changes in the world demand for agricultural commodities, and…

A small open economy in the Great Depression: the case of Switzerland

In historical accounts of the world economic crisis of the 1930s, Switzerland is known for its staunch defense of the gold standard and the rise of corporatist policies. Yet, so far, the literature has not discussed the implications of these two features. This paper tries to show how the combination of hard-currency policy and nominal rigidities introduced by corporatist policies…
