Beyond Work Ethic: Religion, Individual and Political Preferences

We investigate the effect of Reformed Protestantism, relative to Catholicism, on preferences for leisure, and for redistribution and intervention in the economy. We use a Fuzzy Spatial Regression Discontinuity Design to exploit a historical quasi-experiment in Western Switzerland, where in the 16th century a hitherto homogeneous region was split and one part assigned to adopt Protestantism. We find that Reformed Protestantism reduces referenda voting for more leisure by 12, for redistribution by 7, and for government intervention by 6 percentage points. These preferences translate into higher per capita income as well as greater income inequality.

Higher bank capital requirements and mortgage pricing: evidence from the Countercyclical Capital Buffer (CCB)

How has the CCB affected mortgage pricing after Switzerland became the first country to activate this Basel III macroprudential tool? By analyzing a database with several offers per mortgage request, we construct a picture of mortgage supply and demand. We find, first, that the CCB changes the composition of mortgage supply, as relatively capital-constrained and mortgage-specialized banks raise prices more than their competitors do. Second, risk-weighting schemes linked to borrower risk do not amplify the CCBs effect. To conclude, changes in the supply composition suggest that the CCB has achieved its intended effect in shifting mortgages from less resilient to more resilient banks, but stricter capital requirements do not appear to have discouraged less resilient banks from risky mortgage lending.

Cash-on-Hand and the duration of job search. Quasi-experimental evidence from Norway

We identify the causal effect of lump-sum severance payments on non-employment duration in Norway by exploiting a discontinuity in eligibility at age 50. We find that a severance payment worth 1.2 months earnings at the median lowers the fraction re-employed after a year by six percentage points. Data on household wealth enable us to verify that the effect is decreasing in prior wealth, which favors an interpretation as liquidity constraints over the alternative of mental accounting. Finding liquidity constraints in Norway, despite its equitable wealth distribution and generous welfare state, means they are likely to exist also in other countries.

Income Taxes, Sorting, and the Costs of Housing: Evidence from Municipal Boundaries in Switzerland

This paper provides novel evidence on the role of income taxes for residential rents and spatial sorting. Drawing on comprehensive apartment-level data, we identify the effects of tax differentials across municipal boundaries in Switzerland. The boundary discontinuity design (BDD) corrects for unobservable location characteristics such as environmental amenities or the access to public goods and thereby reduces the estimated response of housing prices by one half compared to conventional estimates: we identify an income tax elasticity of rents of about 0.26. We complement this approach with census data on local sociodemographic characteristics and show that about one third of this effect can be traced back to a sorting of high-income households into low-tax municipalities. These findings are robust to a matching approach (MBDD) which compares identical residences on opposite sides of the boundary and a number of further sensitivity checks.

The Causal Effect of House Prices on Mortgage Demand and Mortgage Supply

We identify the causal effect of house prices on mortgage demand and supply in Switzerland by exploiting exogenous shocks to immigration and thereby to house prices. Detailed micro data allow us to observe multiple offers for each mortgage request. We find a 1% increase in house prices to raise the requested mortgage amount by 0.52%. Due to positive feedback effects, the entire partial correlation is 0.78%. While we find higher house prices to increase mortgage demand, they induce banks to make fewer offers and charge higher rates, especially later in the boom and especially for highly leveraged households.

Do immigrants take or create residents' jobs? Quasi-experimental evidence from Switzerland

We estimate the causal effect of immigration on unemployment, employment and wages of resident employees in Switzerland, whose foreign labor force has increased by 32.8% in the last ten years. To address endogeneity of immigration into different labor market cells, we develop new variants of the shift-share instrument that exploit only that part in the variation of immigration which can be explained by migration push-factors in the source countries. While OLS estimates suggest that immigrants have crowded out natives, our quasi-experimental results reveal that immigration has in fact reduced unemployment and increased employment of residents in the last decade.
