Whilst tuberculosis was first found in badgers 34 years ago it is in fact quite understandable that the question is still asked as to whether badgers do spread TB to cattle. The political discomfort that surrounds this problem and the action necessary to address it is such that the politicians have done their best to wish it away.

On the other hand, programmers are increasingly turning to managed languages like Java for their functionality, programmability, and reliability. Managed languages, however, are not known for their memory efficiency, creating a tension between productivity and performa...

This paper asks whether the income gap between rich and poor nations can be explained by multiple equilibria. We explore the quantitative implications of a simple two sector general equilibrium model that gives rise to multiplicity, and calibrate the model for a large number of countries. Under the assumptions of the model, around a quarter of the world’s economies are found to be in a low outp...

U.S. legal changes have made it easier to obtain patents on inventions that use software. Software patents have grown rapidly and now comprise 15 percent of all patents. They are acquired primarily by large manufacturing firms in industries known for strategic patenting; only 5 percent belong to software publishers. The very large increase in software patent propensity over time is not adequate...

We reconsider the issue of price discovery in spot and futures markets. We use a threshold error correction model to allow for arbitrage opportunities to have an impact on the return dynamics. We estimate the model using quote midpoints, and we modify the model to account for time-varying transaction costs. We find that a) the futures market leads in the process of price discovery and that b) t...
