We consider a class of problems, which we call “SFQ” problems, in which both stocks and ows can be controlled to promote the quality of a valued resource, such as environmental quality or public infrastructure. Under the optimal policy, periodic restoration of the stock of quality complements positive but variable abatement of the ow of damages. When deterioration is more rapid or highly vari...

This paper examines the mechanism through which pro-growth policies such as government spending on infrastructure might a¤ect the dynamics of inequality. We develop a model in which government-provided infrastructure is not only the engine of growth, but also a critical determinant of the distributions of wealth, income, and welfare. Government spending on infrastructure by itself is shown to b...

We present a theoretical model of the provision of a durable public good over an in…nite horizion. In each period, there is a societal endowment of which each of  districts owns a share. This endowment can either be invested in the public good or consumed. We characterize the planner’s optimal solution and time path of investment and consumption. We then consider alternative political mechanis...

In this paper we construct a standard CGE model to explore the impact of scaling up infrastructure in an African country. As the debate on the importance of scaling up infrastructure to stimulate growth and provide a push to African economies, some analyst raise concern on financing these infrastructures after construction and that external funding of these can create major distortion and have ...

technological developments in various sectors and considering the speed and accuracy as an integral part of the decision-making process in the age of knowledge economy, has caused the disaster economy an important role in risk assessment and management in national and regional planning. the development of models used in this area, resulted in considering indirect consequences of disasters on th...

Spillovers have attracted wide attention in the areas of research in economics during the past decades. The reason for the interest in the topic lies in their important role in endogenous growth theory and the explanation of productivity growth. This paper investigates the spatial spillover of different types of public infrastructure on economic growth across EU-28 NUTS-II regions during 1995-2...
