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...

The n total consumers in the market for a particular good are made up of b brown and g green consumers so that b+g=n. The b brown (g green) consumers are not (are) environmentally conscious and hence they prefer to buy a new (remanufactured) good denoted by N and R respectively. By strategically...

We analyze a market for microfinance in a region of a developing nation in which all projects are either of high or low quality. There is adverse selection because only borrowers know whether their project is of high or low quality but the microfinance institutions (MFIs) do not. The MFIs are...

We focus on an aggregate economy of two nearby cities A and B and study whether it is possible for the leviathan governments in these two cities to use taxes τA and τB to attract members of the so-called creative class. The creative class population is fixed and members locate either in city A...

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 use a Stackelberg differential game to model trade in renewable resources between a monopsonistic buyer and a monopolistic seller. The buyer uses unit and ad valorem tariffs to indirectly encourage conservation of the resource under study. First, we show that the efficacy of these tariffs in...

We analyze the impact of preference matching and income on the distribution of the population in an aggregate economy of an urban and an adjacent rural region. It costs more (less) to live in the urban (rural) region. Individuals choose to live either in the urban or in the rural region. They...

We exploit the public good attributes of information and communication technologies (ICTs) and theoretically analyze an aggregate economy of two smart cities in which ICTs are provided in either a decentralized or a centralized manner. We first determine the efficient ICT levels that maximize...
