We derive the central differential equation of the neoclassical growth model for the case of a CES (constant elasticity of substitution) production function with perfect capital movement in terms of the debt/GDP ratio and estimate it in several ways for the United States and in a later step the...

We show empirically that aid given to poor developing countries enhances growth and reduces emigration once several dynamically interacting effects of aid are taken into account in a system of equations. We estimate equations for net immigration flows as a share of the labour force and GDP per...

Remittances may have an impact on economic growth through channels to physical and human capital. We estimate two variants of an open economy model of these two channels consisting of seven equations using the general method of moments with heteroscedasticity and autocorrelation correction...

The impact of migration and worker remittances on literacy, accumulation of capital and growth is analyzed for a panel of countries with per capita income below $1200 (2000). We estimate regressions for dynamic equations of migration, worker remittances, savings, investment, tax revenues, public...

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 examines the extent to which dependence on primary commodities in Sub-Saharan African(SSA) countries can be explained by low levels of absorptive capacity (the ability to acquire, internalize and utilize knowledge developed elsewhere). We examine the individual and combined effects of...

Environmental regulation and competitiveness are issues that seem to be at odds. However, the `Porter Hypothesis' states that firms can actually gain in competitiveness if they are subject to stricter environmental regulation. We show in a simple model the basic setting of the problem to apply...

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...

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,...

How much does public capital matter for economic growth? How large should it be? This paper attempts to answer these questions, taking the case of SSA countries. It develops and estimates a model that posits a nonlinear relationship between public investment and growth, to determine the...
