We present identification and estimation results for the 'collective' model of labour supply in which there are discrete choices, censoring of hours and non-participation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied...

We construct a structural model of household decision-making and matching and estimate the returns to schooling within marriage. We consider agents with idiosyn- cratic preferences for marriage that may be correlated with education, and we allow the education levels of spouses to interact in...

We consider a simple model of competition under moral hazard with constant return technologies. We consider preferences that are not separable in effort: marginal utility of income is assumed to increase with leisure, especially for high-income levels. We show that, in this context, Bertrand...

One often heard counter to the concern on rising income and wealth inequality is that it is wrong to focus on inequality of outcomes in a “snapshot.” Intergenerational mobility and “equality of opportunity”, so the argument goes, is what matters for normative evaluation. In response to...

Two stylized representations are often found in the academic and policy literature on informality and formality in developing countries. The first is that the informal (or unregulated) sector is more competitive than the formal (or regulated) sector. The second is that contract enforcement is...

Two decades ago, 93% of the world’s poor lived in countries officially classified as Low Income (LICs). Now, 72% of the world’s poor live in Middle Income Countries (MICs). The dramatic shift has been brought about by fast growth in a number of countries with large populations. On present...

In many markets in developing countries, especially in remote areas, middlemen are thought to earn excessive profits. Non-profits come in to counter what is seen as middlemen's market power, and rich country consumers pay a 'fair-trade' premium for products marketed by such non-profits. This...

This Paper establishes and explores the implications of a somewhat surprising empirical finding. Although civil war adversely affects the performance of social indicators in general, poorer countries lose less, in absolute and relative terms, than richer countries. It is argued that the...

The ratification of ILO Labour Standards Conventions is a key explanatory variable in the empirical literature linking labour standards to economic performance. The assumption is that ratification gives information about labour standards implemented in a country. This Paper investigates the...

A simple model of North-South interaction is presented with a Keynesian North producing industrial goods and a Classical South producing corn. If the terms of trade clear the corn market then commodity price stabilisation can only slightly increase the average value of Northern real consumption....
