We study the recent evolution of top incomes in Switzerland, analyzing both social security data on labor incomes and tax data on total income. The results show that in the last 20 years, the share of top incomes has risen, and the top 0.01 percent’s share even doubled, putting Switzerland...

Unilateral second-best carbon taxes are analysed in a two-period, two-country model with international trade in final goods, oil and bonds. Acceleration of global warming resulting from a future carbon tax is large if the price elasticities of oil demand are large and that of oil supply is...

Since World War II, direct stock ownership by households has largely been replaced by indirect stock ownership by financial institutions. We argue that tax policy is the driving force. Using long time-series from eight countries, we show that the fraction of household ownership decreases with...

This Paper studies the positive aspects of destination vs. origin principles of commodity taxation as well as tax harmonization, with an emphasis on the international implications of these measures when firms are mobile. We investigate the tax incidence of these two principles on price levels...

We study the impact of local taxation on the location and growth of firms. Our empirical methodology pairs establishments across jurisdictional boundaries to estimate the impact of taxation. Our approach improves on existing work as it corrects for unobserved establishment heterogeneity, for...

Economists traditionally tackle normative problems by computing optimal policy, ie the one that maximizes a social welfare function. In practice, however, a succession of marginal changes to a limited number of policy instruments are implemented, until no further improvement is feasible. I call...

This Paper explores the optimal role of the tax system in alleviating labour-market imperfections and raising revenue. For this purpose, the standard search model of the labour market is extended by introducing scarce entrepreneurial talent and arbitrage between the supply and demand. We study...

The paper deals with the distributional effects of immigration into Switzerland. Focusing on the government budget, it explores empirically whether resident foreigners are a burden or a benefit to the Swiss public transfer system. The estimation is based on the 1990 Consumer Survey by the Swiss...

We study how the level of trade costs and the intensity of competition can explain the existence of two-way, one-way or no trade within the same industry. As trade costs decrease from very high to very low values, the economy moves from autarky to a regime of two-way trade, through a regime of...

The present study provides estimates of the Effective Marginal Tax Rates (EMTRs) for a sample of 17 OECD countries and 11 manufacturing sectors in a single framework encompassing capital, labour and energy taxes. Our cross-country/cross-sector approach allows us comparing the incentives provided...
