This paper considers the extension to panel data of models that are specified cross-sectionally in terms of a likelihood. It considers specifically the estimation of stochastic frontier models but the same issue arises in many other models. The model can be estimated for any single value of the...

In this paper we introduce a flexible target zone model that is capable of characterizing the dynamic behaviour of an exchange rate implied by the original target zone model of Krugman (1991) and its modifications. Our framework also enables the modeller to estimate an implicit target zone if it...

It is quite often in economics that we wish to model a discrete ordered random variable, such as bond ratings, employment status, consumption levels and so on. However, traditional approaches to modelling such a discrete ordered random variable ignore both the potential build-up of zero...

The distributional effects of food pricing policy are controversial everywhere, particularly in developing countries. Indonesia is a good example, where rice is a net import and accounts simultaneously for a large share of consumers' budgets and a large share of total employment. For the poor,...

A central proposition on which much of normative economics is founded asserts that if two or more adults voluntarily agree to an exchange or trade and this does not have a negative fall-out on others, then government should not stop this exchange. Yet, on a variety of matters (hazardous work,...

This paper studies optimal asset allocation to stocks, long-term bonds and T-bills and consumption choice in the presence of regime switching in asset returns. Optimal asset allocations vary considerably across four states - both across bonds and stocks and among large and small stocks - and...

This paper explores the role of unobserved managerial ability in production and its relationship with technical efficiency. Previous analyses of managerial ability have been based on strong assumptions about its role in production or the use of proxies. We avoid these shortcomings by introducing...

Despite a growing literature in the application of Conditional or Mixed Logit methods to the estimation of labour supply models, relatively little attention has been paid to the role of institutional constraints in employment choices. We argue that the failure adequately to control for...
