I examine how globalization affects wages and welfare in a general equilibrium model of international trade with partly oligopolistic markets. Globalization is modeled as reducing trade costs or opening up shielded sectors to trade. There is a national or international common agency that determines minimum wages for the oligopolists, either directly or through supporting labor unions. The lobbies of employers and labor unions influence that agency, relating their prospective political contributions to the latter's decisions. Both a shift from national to international regulation and a decrease in trade costs promote aggregate welfare, but decrease open-sector relative wages.

In this paper, I study the political rationale for labor market regulation. Oligopolists employ raw labor and human capital (i.e. key workers) for production and R&D. There are many jurisdictions, in each of which a self-interested policy maker can regulate/deregulate the local labor market. I show that the observed tendency to labor market deregulation results from labor market policies being set up at the local level. In small jurisdictions, the fall of income due to wage increases is so large that the labor markets are deregulated. With labor market integration, jurisdictions get larger and face less competition from outside. Then, the fall of income due to wage increases is reduced and labor market regulation becomes more attractive to workers' lobbies.

AbstractOptimal population policy is examined in the following setup. Families invest in capital, spend on health care and determine their number of children. Firms produce output from labor, capital and pollutants. Pollution increases, but private and public health care decrease mortality dynamically, with lags. Our main findings are the following. A marginal increase in public health care improves welfare as long as it diminishes the mortality rate more than that in private health care. The government can decentralize the social optimum by a parental tax on newborns and a Pigouvian tax on pollutants. Private health care should not be taxed.

The book examines problems associated with green growth and sustainable development on the basis of recent contributions in economics, natural sciences and applied mathematics, especially optimal control theory. Its main topics include pollution, biodiversity, exhaustible resources and climate change. The integrating framework of the book is dynamic systems theory which offers a common basis for multidisciplinatory research and mathematical tools for solving complicated models, leading to new insights in environmental issues.?
