We study how gradualism -- increasing required levels (""thresholds"") of contributions slowly over time rather than requiring a high level of contribution immediately -- affects individuals' decisions to contribute to a public project. Using a laboratory binary choice minimum-effort...

We conduct experiments in urban slums to measure trust and cooperation and to see how behavior varies with demographic factors and associational measures of social capital. Overall, we find high contribution rates among Thai and Vietnamese participants in a voluntary contribution game, and we...

Several economists have maintained that social and internalized norms can enforce cooperation in public good situations. This experimental study investigates impacts of social and internalized norms for cooperation among strangers in a public good game. The experiment has two treatment effects....

The purpose of this paper is to introduce and adopt a generalised version of Roemer's (1998) Equality of Opportunity (EOp) framework, which we call extended EOp, for analysing second-best optimal income taxation. Unlike the pure EOp criterion of Roemer (1998) the extended EOp criterion allows...

A methodology to describe the distributional and behavioural effects of child care subsidies is presented within a micro simulation framework. We discuss the effects of changing the governmental policy to support families with preschool children, from today's subsidisation of spaces at child...

The purpose of this paper is to introduce and adopt a generalised version of Roemer's (1998) Equality of Opportunity (EOp) framework for analysing optimal income taxation. EOp optimal tax rules seek to equalise income differentials arising from factors beyond the control of the individual....
