Signal generation is one of the most critical problems in the microwave and millimeter-wave communication market. The demands of greater stability and low phase noise further increase complexity in the circuit design. Signal generation in the millimeter-wave bands can be realized either directly by an oscillator or by multiplication from a lower frequency. An effective solution is to multiply t...

Estimation of the employment effects of changes in capital investment is a standard tool in public policy debates. Typically, such predictions are based on employment multipliers derived from Input–Output analysis. In this paper, we measure the employment effects of changes in capital investment in the U.S. information sector by econometrically estimating an “employment multiplier” from histori...

This paper performs multiple-break unit root tests on the data of China’s national and sectoral output and labour productivity, with finite-sample critical values bootstrapped through Monte Carlo simulations. We find strong evidence against the unit-root hypothesis in favour of the segmentedtrend-stationarity alternative. Based on breaking trend functions, the steady-state and transitional grow...

the input - output framework is applied in this study to analyse the change, in the use of labor input. on the basis of input-output tables sectors of the economy are specified according to the degree of their interdependences. backward and forward employment linkages can he calculated. the sectors then are classified according to their total (direct and indirect) employment linkages. through a...
