In this paper we integrate two workhorse models in economics: The monopolistic competition model of Dixit and Stiglitz and the search unemployment model of Pissarides. Information and communication technology (ICT) is interpreted as i) technical progress in the matching function of the...

We argue that a conventional double dividend policy - defined as reduction of greenhouse gas emissions and unemployment through taxation of energy and CO2 emissions and subsidization of wage costs - and the aim of keeping international competitiveness intact are mutually exclusive concepts. It...

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 consider the problem between an employer and a research employee who has not finished a research project in time because of a lack of an innovative idea. The research project yields money in case of finishing it. The decision to be made is whether or not the researcher gets a contract...

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....

In this paper we show conditions under which the accumulation of public infrastructure capital over time may create the comparative advantage of the production of transport services and destroy that of the production of goods in a market equilibrium of a transit economy. We also show conditions...

The Porter Hypothesis postulates that the costs of compliance with environmental standards may be partially or even fully offset by adoption of innovations they trigger. The timing of the adoption aspect of the Porter Hypothesis has not been captured in formal theory so far. We show in this...

This paper focuses on a model in which low (high) export demand elasticities and the fact that developing countries are importers of capital goods help explaining the slow (high) growth of these countries. The question arises whether export demand elasticities are low or high. For answering this...

In this paper we develop a simple neoclassical growth model with perfect international capital mobility to analyze the stability of the differential equation in the foreign debt/GDP dynamics of developing countries in general and Korea, Malaysia and Thailand in particular in the long run using...
