We study voluntary contribution behavior of individuals who vary in their ability to contribute to a joint project under different information scenarios. We investigate a situation with two types who vary only in their external marginal return (low and high). Results of a laboratory experiment...

This paper discusses the choice of the number of participants for within-subjects (WS) designs and between-subjects (BS) designs based on simulations of statistical power allowing for different numbers of experimental periods. We illustrate the usefulness of the approach in the context of field...

This article experimentally examines voluntary contributions when group members’ marginal returns to the public good vary. The experiment implements two marginal return types, low and high, and uses the information that members have about the heterogeneity to identify the applied contribution...

The role of field experiments in evaluating the effect of compensation policies on worker productivity is considered. Particular attention is paid to the ability of a field experiment to identify the effect of a permanent change in firm policy. While field experiments solve endogeneity problems...

Data from a field experiment conducted within a tree-planting firm are used to estimate the gain in productivity that is realized when workers are paid piece rates rather than fixed wages. The experiment provides daily observations on individual worker productivity under both piece rates and...

In 2002 the Government of Quebec enacted Bill 112, known as An Act to Combat Poverty and Social Exclusion. It has also instituted an advisory committee whose role is to advise the government on policies that may have a direct or indirect impact on poverty and social exclusion. The Committee...

We develop and estimate a generalized labour supply model that incorporates work effort into the standard consumption-leisure trade-off. We allow workers a choice between two contracts: a piece rate contract, wherein he is paid per unit of service provided, and a mixed contract, wherein he...

More than ten years ago, to increase mothers’ participation in the labour market and to enhance child development, the province of Québec implemented a $5 per day universal childcare policy. This paper provides a comprehensive review of the costs and benefits of the program over that period....

To increase mother’s participation in the labour market and enhance child development, the Canadian province of Québec developed from 1997 a large scale low-fee childcare network. Previous studies have shown that the policy has significantly increased the labour force participation and annual...

Le financement public des services de garde (SDG) est au cœur d’objectifs multiples au Québec et ailleurs au Canada. Cet article rapporte l’impact des trois mesures principales de financement public (le crédit d’impôt provincial, la déduction d’impôt fédérale, et les subventions...
