Random taxation may be optimal when the taxpayers differ in their attitudes towards risk, so that tax randomization enables the government to relax the incentive constraints. The paper provides a necessary and sufficient condition for local random deviations to be welfare improving in a...

An optimal contract may involve randomization when the agents differ in their attitudes towards risk, so that randomization enables the principal to relax the incentive constraints. The paper provides a necessary and sufficient condition for local random deviations to be welfare improving in a...

In this article, the size of informal economy is measured by using the full price method proposed by Gardes F. (2014). As an extension of this method, price elasticities are re-estimated by integrating the underreported earning shares both for wage workers and self-employers from cross-sectional...

In this article, we propose to calculate the size of the population living in poverty, measured through uni- and multidimensional poverty indices, and the Gini coefficient using extended full (time plus money and informal earnings) incomes, from cross-sectional data covering 2003-2006 in Turkey....

We investigate underlying determinants of informality by representing the Turkish Time Use Survey in 2006 and the Household Budget Surveys for the years from 2003 to 2006 conducted by Turkish Statistical Institute. Following the descriptive methodology proposed by Gronau and Hamermesh (2006),...

We use the demand system approach to estimate the size of informal economy in Turkey following the methodology based on the analysis of the individual consumption behaviour proposed by Pissarides, Weber (1989), Lyssiotou et al. (2004), and Fortin et al. (2009). We extend this method by taking...

This paper proposes an empirical analysis of the declining support for the German Social Democratic Party (SPD) during Schröder government's second term of office, which was marked by major reforms in the fields of unemployment insurance and labour market policy (Hartz reforms). Drawing on a...

We use the demand system approach to estimate the size of informal economy in Turkey following the methodology based on the analysis of the individual consumption behaviour proposed by Pissarides, Weber [1989], Lyssiotou et al. [2004] and Fortin et al. [2009]. We extend this method by taking...

This paper questions the determinants of infrastructure privatization in Djibouti and seeks to explain why this policy is still implemented today. Through case studies, the paper analyses the privatization processes of the port, electricity, and railway sectors. The paper shows that...

We examines the challenges faced by the regulator in managing pollution when there is a linkage between a formal and an informal industrial sector across the stages of production. The formal sector is more productive than the informal sector and the latter saves cost by evading pollution...
