The author raises the classic question of welfare economics in relation to invention: to what extent does perfect competition result in optimal allocation of resources? There are three reasons for the possible failure of perfect competition to lead to optimal resource allocation: marginal-cost...

We study an economy in which the rate of change of population depends on population policy decisions. This requires population as well as capital as state variables. By showing the algebraic relationship between the shadow price of the population and the shadow price of the per capita capital...

As economists, we believe that the Second Circuit's ruling, by not allowing the consideration of important information about the relationships between the benefits and costs of alternatives, is economically unsound. In particular, we believe that, as a general principle, regulators cannot make...

It is well-known that 50% or more of all jobs are obtained through informal channels i.e. connections to family or friends. As well, statistical studies show that observable individual factors account for only about 50% of the very wide variation in earnings. We seek to explain these two facts...

The paper sets a broad agenda touching several areas of policy. It starts from the least likely policy at this point of time, the use of the tax system for redistribution.

We are interested in three related questions: (1) How should accounting prices be estimated? (2) How should we evaluate policy change in an imperfect economy? (3) How can we check whether intergenerational well-being will be sustained along a projected economic programme? We do not presume that...

The extent of genetic diversity in food crops is important as it affects the risk of attack by pathogens. A drop in diversity increases this risk. Farmers may not take this into account when making crop choices, leading to what from a social perspective is an inadequate level of diversity

This report addresses a deceptively simple question: How can the productivity of American health care be substantially improved? Productivity, in lay terms, is the ratio of output to inputs. A more colloquial rendition of the question might be: how can we get a lot more bang for our health care...
