This paper presents a Dynamic Computable General Equilibrium Model that analyses impacts of public spending in education on student's behaviours and labour market. The South African education system faces with strong inequalities inherited from the Apartheid regime. We find that this policy...

As evidence accumulates to expose the ineffectiveness of foreign aid, there are increasing calls for rich countries to open up their immigration policies so as to enable migrants' remittances to substitute for foreign aid as a growth-stimulant in poor, migrant-sending countries. In this paper,...

This paper uses sequential stochastic dominance procedures to compare the joint distribution of health and income across space and time. It is the first application of which we are aware of methods to compare multidimensional distributions of income and health using procedures that are robust to...

Homophily, the tendency of linked agents to have similar characteristics, is an important feature of social networks. We present a new model of network formation that allows the linking process to depend on individuals types and study the impact of such a bias on the network structure. Our main...

We develop a reciprocity-based model of wage determination and incorporate it into a modern dynamic general equilibrium framework. We estimate the model and find that, among potential determinants of wage policy, rent-sharing (between workers and firms) and a measure of wage entitlement are...

In this paper, we study the macroeconomic implications of sectoral heterogeneity and, in particular, heterogeneity in price setting, through the lens of a highly disaggregated multi-sector model. The model incorporates several realistic features and is estimated using a mix of aggregate and...

Unemployment insurance policies are multidimensional objects. They are typically defined by waiting periods, eligibility duration, benefit levels and asset tests when eligible, which make intertemporal or international comparisons difficult. To make things worse, labor market conditions, such as...

We present a general equilibrium model of monopolistic competition featuring pro-competitive effects and a competitive limit, and investigate the impact of trade on welfare and efficiency. Contrary to the constant elasticity case, in which all gains from trade are due to product diversity, our...

Favoritism is the act of offering jobs, contracts and resources to members of one's social group in preference to outsiders. Favoritism is widely practiced and this motivates an exploration of its origins and economic consequences. Our main finding is that individuals have an interest to trade...

Consider an n-person economy in which efficiency is independent of distribution but the cardinal properties of the agents’ utility functions precludes transferable utility (a property we call “Almost TU”). We show that Almost TU is a necessary and sufficient condition for all agents to...
