We study the political economy of the environment in autocratic, weak and strong democracies when individuals can either mitigate the health consequences of domestic pollution privately or reduce pollution collectively through public policy. The setting is that of a small open economy in which...

We present a two-good, two-country overlapping generations model where emissions arise from production and each country has a domestic emission permit system. When one country unilaterally reduces her cap on emissions, her output available for domestic and foreign consumption diminishes more...

Worker movements played a crucial role in making workplaces safer. Workplace safety is costly for firms but increases labour supply. A laissez-faire approach leaving safety of workplaces unknown is suboptimal. Safety standards set by better-informed trade unions are output and welfare...

We construct a general equilibrium trade model of a two-class small open host or source country. When consumption tax revenue finances the provision of a public good, marginal migration reduces social welfare in the source country and raises it in the host. When consumption tax revenue is...

This paper elaborates on the recent race to sequence the human genome. Starting from the debate on public vs. private research arising from the genome case, the paper shows that in some fundamental research areas, where knowledge externalities play an important role, market and non-market...

The paper analyses the welfare effects of immigration when some sectors of the economy are characterized by wage bargaining between unions and employers. We show that immigration is unambiguously beneficial if the wage elasticity of labor demand in the competitive sectors is smaller than in the...

Previous research on optimal R&D subsidies has focussed on the long run. This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method. Starting from the steady state under current R&D subsidization in...

A finite number of sellers (n) compete in schedules to supply an elastic demand. The costs of the sellers have uncertain common and private value components and there is no exogenous noise in the system. A Bayesian supply function equilibrium is characterized; the equilibrium is privately...

We consider the optimal education policies of a small economy whose government has a limited budget. Initially, the economy is closed and the government chooses its education policy to maximize welfare under autarky. Then the economy trades with the rest of the world. Lastly, the government...

Physical stature is used as a proxy for the biological standard of living in thetwo Germanies before and after unification in an analysis of a cross-sectionalsample (1998) of adult heights, as well as among military recruits of the1990s. West Germans tended to be taller than East Germans...
