Demand for Fuel and its Consequences for Indirect Taxation: A Microeconomic View

The author uses microeconomic theory, particularly demand theory, and econometrics to investigate the impact of proposed tax changes on the consumers. The effect of taxation can be investigated in two ways: the first possibility is to construct a multi-equation model able to analyze all taxes simultaneously. The second is to create a partial model for a specific tax, which would register subtler effects. The second approach is adopted here, with an exclusive focus on fuel-product excise taxes and their microeconomic impact. Two alternative approaches, instrumental variables and the Heckman two-step selection model, are used to estimate the demand function for fuel. The estimated demand function is then used toward a tax simulation and an investigation of the tax- -change effects on different segments of the population.consumer demand, excise taxes, tax simulation, nonparametric regression

Labor supply after transition: evidence from the Czech Republic

We extend the scarce evidence on labor supply in post-transition countries by estimating the wage elasticity of labor force participation in the Czech Republic. Using the household income survey data of 2002, we find that a one-percent rise in the gross wage increases the probability of working by 0.16 and 0.02 percentage points for women and men, respectively. Taking into account the tax and benefit system, these semi-elasticities fall to 0.06 for women and 0.01 for men. We interpret the difference between the estimates from the two specifications as a summary measure of the welfare system disincentives. The estimated wage elasticities lie at the lower end of the range of values reported for mature market economies. This finding is consistent with the stylized fact that the labor supply in countries with high labor force participation rates, such as in the Czech Republic, tends to be less sensitive to wages.

Fiscal developments and financial stress: a threshold VAR analysis

We use a threshold VAR analysis to study whether the effects of fiscal policy on economic activity differ depending on financial market conditions. In particular, we investigate the possibility of a non-linear propagation of fiscal developments according to different financial market stress regimes. More specifically we employ a quarterly dataset, for the U.S., the U.K., Germany and Italy, for the period 1980:4-2009:4, encompassing macro, fiscal and financial variables. The results show that (i) the use of a nonlinear framework with regime switches is corroborated by nonlinearity tests; (ii) the responses of economic growth to a fiscal shock are mostly positive in both financial stress regimes; (iii) financial stress has a negative effect on output growth and worsens the fiscal position; (iv) the nonlinearity in the response of output growth to a fiscal shock is mainly associated with different behaviour across regimes; (v) the size of the fiscal multipliers is higher than average in the last crisis.fiscal policy, financial markets, threshold VAR

Human Capital Mobility II

Migration from poorer to richer countries can produce a vicious circle from a gap in real wages through a gap in human capital causing a gap in productivity causing a gap in real wages again. This circle can be linked with another one (based on the effective wage theory) connecting the level of real wages to the prices of non-tradables. Lower wages impact through lower demand on lower prices of non-tradables. Having once lower prices of non-tradables and thus lower wages paid in the non-tradables sector, the real wages in the tradables sector and the general real wages as well are pulled to a lower level. Both circles influence the process of convergence of the Central and East European Countries (CEEC) to the European Union (EU). In this paper, we show different possibilities for the model specification of this basic mechanism, to cover different links between human capital migration to the real wage (equations 4a, b) and different possibilities for human capital formation in the old EU members (equations 5a-e). We show results of parameters’ estimation and some illustrations of model’s dynamics. In conclusions, we discuss where problems with parameters’ estimation may come from and show where farther changes in model’s specification could be done.human capital; mobility; estimation; dynamics
