Nancy Cartwright views models as blueprints for nomological machines - machines which, if properly shielded, generate lawlike behaviour or regularities. Marcel Boumans has argued that we can look for devices inside models which enable us to measure aspects of these regularities. So, if models do...

There has been a revival of interest in the effect of risk on economic growth. We quantify both ex ante and ex post … effects of risk using a stochastic version of the Ramsey model. We develop a simulation-based econometric methodology which … remarkable long-running panel data set for rural households in Zimbabwe. We find that risk substantially reduces growth: in the …

Most measures of vulnerability are a-theoretic and essentially static. In this paper we use a stochastic Ramsey model to find a household's optimal welfare and we measure vulnerability as the shortfall from the welfare attained if the household consumed permanently at the poverty line. The...

The risk of investment in schooling has largely been ignored. We assess thevariance in the rate of return by surveying … skewed. Our best guess of ex ante risk in university education is a coefficient ofvariation of about 0.3, comparable to that …

This paper … integrates risk into the standard inequality measurement which measures the extent to which disparities in realized health are … account for risk averse preferences in the assessment of income-related health inequalities.

We study the optimal taxation of risk-free and excess capital income with heterogeneous rates of return, alongside an … optimal nonlinear earnings tax. Households can hold three assets: one risk-free, one risky but diversifiable, and one a … private investment with idiosyncratic risk whose expected return differs among households. Contrary to expectations, the …
