The Porter Hypothesis postulates that the costs of compliance with environmental standards may be offset by adoption of innovations they trigger. We model this hypothesis using a game of timing of technology adoption. We show that times of adoption are earlier the higher the non-adoption tax....

This paper argues that immigration can help to alleviate the burden ageing presents for the welfare states of most Western Economies. We develop a macroeconomic framework which deals with the impact of both ageing and immigration on economic growth. This is combined with a detailed model of the...

In regressions for net immigration flows of developing countries we show that (i) savings finance emigration and worker remittances serve to make staying rather than migrating possible until a certain value, beyond which the opposite holds; (ii) lagged dependent migration flows have a negative...

We are interested in the relation between Gini coefficients of education, educational variables, and growth. We specify a system of 14 difference equations with lagged dependent variables in education variables, as well as a growth regression, auxiliary equations for savings and investment...

The credit crisis of OECD countries has a negative impact on the growth of the world economy according to a simple error correction model. This causes negative growth effects in poor developing countries. The reduced growth has a direct or indirect impact on the convergence issue, aid,...

The debate about the Prebisch-Singer thesis has focussed on primary commodities with some extensions to manufactures. As we think that the link between the terms of trade and longrun development, growth and convergence is the ability of exports to enhance investment through importing capital...

We investigate the impact of aggregate aid, earmarked aid, committed or disbursed, on social indicators in health and education. A literature review shows that for earmarked aid use of commitment data mostly leads to insignificant results; use of disbursement data mostly leads to significantly...

We estimate the impact of worker remittances on savings, taxes, and public expenditures on education, all as a share of GDP, for about thirty years in two samples of countries with per capita income above and below $1200 using dynamic panel data methods. Governments of the poorer sample raise...

We show that the credit crisis of OECD countries has a negative impact on the growth of the world economy according to an error correction model including China and Australia. This causes negative growth effects in poor developing countries. The reduced growth has a direct or indirect impact on...

In dealing with a transnational pollutant-emitting duopoly welfare-maximising policy makers face two negative externalities: imperfect competition and unpriced emissions. Strategic environmental policy models show that these externalities involve a trade-off between reducing pollution and...
