We show here the transient activation of the small GTPase Rac, followed by a rise in reactive oxygen species (ROS), as necessary early steps in a signal transduction cascade that lead to NFkappaB activation and collagenase-1 (CL-1)/matrix metalloproteinase-1 production after integrin-mediated cell shape changes. We show evidence indicating that this constitutes a new mechanism for ROS productio...

Evaluation of the Underground Economy in Quebec: A Microeconomic Approach The main purpose of this paper is to estimate the size and the growth of Quebec’s underground economy, and the corresponding loss of taxes for the government. Our approach is based on a method developed by Pissarides and Weber (1989) and extended by Lyssiotou et al. (2004). The basic hypothesis is that individuals can und...

The complexity of the individual income tax system can give rise to both under and overreporting of liability, thus creating a wedge between taxpayer perceptions of the price of public services and their actual cost, and potentially leading to budget misallocations and associated efficiency losses. This study uses theory and experiments to evaluate the effectiveness of taxpayer service programs...

This paper presents a search and matching model to account for the most salient facts of labor markets with informal jobs in developing countries. The data suggests that workers reallocate from formal jobs into informal jobs in recessions, as well as when policy makers intervene in the market. This reallocation is mainly driven by the large and procyclical swings of the job …nding rate in the f...

In this study, we explore factors that determine citizens’ tax compliance attitude in Kenya, Tanzania, Uganda and South Africa. The analysis is based on attitude and perception data from the new round of Afrobarometer surveys, which contain more tax-specific information than previous rounds. Using binary logit regression, we find some similarities, but also differences in factors that are corre...

underground economy affects important indexes such as formal gdp, unemployment, consumption, production and etc. therefore it is necessary to identify elements and factors which affect underground economy to restrict it. surveys and studies indicate the size of iran’s underground economy is high and taxes, quantity and quality of regulations and performance of formal economy are the important f...
