This paper looks at the impact of education on household economic welfare in Sri Lanka over twenty years from 1985 to 2006 using five cross section household survey datasets.  Applying quantile regression techniques the analysis finds that the incremental value to household welfare shows a...

We examine a variety of preference-based definitions of ambiguous events in the context of the smooth ambiguity model.  We first consider the definition proposed in Klibanoff, Marinacci, and Mukerji (2005) based on the classic Ellsberg two-urn paradox (Ellsberg (1961)), and show that it...

The debate on trade and growth increasingly focuses on the composition of exports.  Exports of more "sophisticated" products appear to be positively correlated with growth, and upgrading the quality of exports is high on the policy agenda of many countries.  This study presents evidence...

We consider three 'cases studies' of the uses and mis-uses of mathematics in economics and econometrics.  The first concerns economic forecasting, where a mathematical analysis is essential, and is independent of the specific forecasting model and how the process being forecast behaves.  The...

This paper studies banker remuneration in a competitive market for banker talent.  I model, and then calibrate, the default risk of the banks generated by investments and remuneration pressures.  Competing banks prefer to pay their banking staff in bonuses and not in wages as risk sharing on...

General unrestricted models (GUMs) may include important individual determinants, many small relevant effects, and irrelevant variables.  Automatic model selection procedures can handle perfect collinearity and more candidate variables than observations, allowing substantial dimension reduction...

Economies are so high dimensional and non-constant that many features of models cannot be derived by prior reasoning, intrinsically involving empirical discovery and requiring theory evaluation.  Despite important differences, discovery and evaluation in economics are similar to those of...

This paper compares the goods and characteristics models of the consumer within a traditional demand framework.  We examine the nonparametric revealed preference conditions for the goods and characteristics models, and we develop a methodology for testing nested models of this class using...

Urbanization has been extensively used as a proxy for economic activity.  The urban status of settlements is usually determined by an ad hoc population size household.  This paper proposes a new threshold, taking into account the effect of local agricultural endowments.  The new population...

Fiscal councils now exist in a number of countries.  This paper first considers the extent of deficit bias, potential explanations for it, and how independent institutions could help reduce it.  Are fiscal councils complements to or substitutes for fiscal rules, and why do none at  present...
