The measurement of achievement growth raises many challenges, including how to define "growth" and select or develop a growth measure that captures that definition. Despite these complications, current federal educational policies focus on student growth measures for accountability purposes....

This paper models the impact on economic growth of HIV/AIDS when the epidemic is in a mature phase, in contrast with previous studies focused on periods of expansion, as in African countries. Simulations for Honduras, the epicenter of the epidemic in Central America, show that AIDS is not likely...

This paper presents a fairly general treatment of recursive infinite horizon forward looking optimizing systems on infinite dimensional spatial domains. It includes optimal control, an analysis of local stability of spatially flat optimal steady states and development of techniques to compute...

This paper develops a two-country two-sector endogenous growth model with a dual labour market based on efficiency wages. Growth is driven by Research done in the (high-tech) tradeable sector. The follower country tends to grow faster the greater the productivity gap from the leader country, but...

This paper explores the effects of an environmental tax reform on pollution, economic growth and welfare in an endogenous growth model with pre-existing tax distortions. We find that a shift in the tax mix away from output towards pollution may raise economic growth through two channels. The...

In this paper we develop a two-sector endogenous growth model with a dual labour market, based on efficiency wages. Growth is driven by intentional R&D performed in the high-tech and high-wage sector. It is examined how a change in rivalry among firms affects simultaneously growth and...
