Personal Income Tax Elasticity in Turkey: 1975-2005

The estimation of tax elasticity; the response of tax revenues to changes in income, is important for at least three reasons: i) formulating government budgets and monitoring tax collections (Sen, 2002), ii) the specification of tax functions, iii) the automatic stabilizing properties of the tax system and the public sector deficit (Hutton, Lambert; 1980, 1982). Among the various approaches to tax elasticity calculation in literature (Tanzi, 1969, 1976; Greytak and McHugh, 1978; Hutton and Lambert, 1980; Ehdaie, 1990), the most famous approach is Tanzi’s Method due to its simplicity and the consensus about its correctness of elasticity estimates. Johansen cointegration tests for the period 1975 - 2005 show that personal income tax elasticity in Turkey is around 0.95, indicating almost unit elasticity. Increasing income can be considered as insurance to maintain an equivalent increase in tax revenue; however it doesn’t seem to be the way to obtain higher tax revenues.Personal income tax, tax elasticity, Tanzi method

The Impact of Shale Energy on Population Dynamics, Labor Migration, and Employment

This paper is designed to determine whether producing oil and gas via shale has an economically significant effect on population migration dynamics and on the labor market in terms of the number of employed individuals, the number of establishments, total wages, and average annual pay per person in twenty-six counties in Ohio and Pennsylvania, USA. The analysis incorporates migration inflow and outflow between producing and nonproducing counties. The results of the analysis show that the counties that engage in shale gas extraction saw a negative impact on net migration but a much larger positive impact on labor market outcomes. Specifically, the number of jobs is higher by 2.4%, the number of establishments is higher by 1.1%, total wages are 3% more and the average annual pay is 1.5% more in producing counties after shale. The analysis reveals a small but statistically significant negative impact on migration, as shale regions experienced some migration outflows
