We first construct three measures of the expected damage from the unintentional introduction of alien species into a country called Home. We then focus on four market structures. First, perfect competition prevails in both Home and Foreign, and Home is a small country. Second, the Home and the...

We propose and develop a new framework for studying the problem of preventing biological invasions caused by ships transporting internationally traded goods between countries and continents. In particular, we apply the methods of queuing theory to analyze the problem of preventing a biological...

Small farmers in many tropical developing countries practice swidden agriculture. A key aspect of swidden agriculture is the time period during which the land is left fallow. This paper uses a new ecological-economic approach to study the fallow period and to determine the optimal length of this...

Queuing mechanisms are commonly used in developing countries and in transition economies to allocate goods characterized by excess demand to citizens. Bribery and favoritism frequently accompany the use of such queuing mechanisms. Therefore, we first analyze a queuing model of resource...

We first construct a theoretical model of tax evasion in a stylized developing country in which all taxpayers have either high or low income. The key problem is that the high-income taxpayers may underreport their income. An individual income tax return can only be verified with an audit that...

We provide the first theoretical analysis of the effects of alternate forms of taxation on economic growth in a dynamic model with multiple regions. The regions are heterogeneous, but, in each region, consumers have constant relative risk aversion preferences, there is no growth in the stock of...
