A Copula Nonlinear Granger Causality

We propose a new copula nonlinear Granger causality test that is more robust than the current available linear and nonlinear Granger causality tests when there exists an asymmetric and nonlinear directional dependence. To perform the statistical test of the copula nonlinear causality, the Gaussian Copula Marginal Regression (GCMR) model and copula directional dependence (Kim and Hwang, 2017) are employed in this paper. By using GCMR and two-sample permutation test with rank sum statistic for the copula nonlinear Granger causality, we can confirm that the result of the proposed copula nonlinear Granger causality test is a reliable test through the simulated data and real data both for small and large sample sizes.

Political legislation cycle in the Czech Republic

Politicians’ efforts to stay in office may lead to the occurrence of political cycles in legislation activity. The aim of this article is to analyze the political legislation cycles in a post-socialist economy of a young democracy, namely in the Czech Republic. Our estimation of the relationship between the number of approved laws and various explanatory variables suggests that the timing of elections has an impact on legislation activity. As an electoral term matures and upcoming elections approach, an increase is observed in legislation activity through which an incumbent government seeks to maximize its chances of re-election.     

Debt and Economic Growth in the European Union: A Panel Granger Causality Approach

This paper contributes to empirical investigation of the causality relationships between real gross domestic product (GDP) growth and the growth of three debt categories, namely public, foreign and private debt, in the universe of the 28 European Union (EU) countries during the past decade. Using panel Granger causality estimations, we find statistically relevant bidirectional causality relationships between public debt and economic growth for the periods both before and after the outbreak of the recent financial crisis. Moreover, there is clear evidence of economic growth’s contribution to decreasing public debt.

Enterprise performance and management turnover in the Czech Republic

We study the effect of management turnover on changes in enterprise performance, using a cross-section of 706 Czech firms over the 1993–1997 period. Controlling for initial conditions, equity holdings by managers, and firm- and sector-specific effects, we find that the appointment of new managers is associated with improvements in profit margins and labor productivity, particularly if those managers were selected by private owners. The results highlight the importance of human capital in transition economies in bringing about improvements in corporate performance.     

Increased sorting and wage inequality in the Czech Republic

This paper makes use of a linked employer–employee dataset to examine the evolution of wage inequality in the Czech Republic during 1998–2006. We find evidence of slightly increasing returns to human capital and diminishing gender inequality and document sharp increases in both within‐firm and between‐firm inequality. We investigate several hypotheses to explain these patterns: increased domestic and international competition, decentralized wage bargaining, skill‐biased technological change and a changing educational composition of the workforce. Domestic competition is found to lower within‐firm inequality whereas we find no evidence that increased international trade at the industry level is associated with higher between‐ or within‐firm wage inequality. The key factors driving the observed increase in wage inequality are increased educational sorting and the inflow of foreign firms to the Czech Republic.

文章应用协整和格兰杰因果检验等经济计量分析方法,对新疆1978～2006年的产业结构变动与经济增长的关系进行了分析,并利用宏观经济模型测算了产业变动对新疆经济增长的贡献.实证分析结果表明:产业结构变动促进了经济增长,而经济增长对产业结构变动没有显著影响.产业结构变动对经济增长的贡献水平还较低.需要制订有效的产业政策优化调整产业结构,以促进新疆经济的快速发展.     

Evaluating changes in the monetary transmission mechanism in the Czech Republic

We investigate the evolution of the monetary policy transmission mechanism in the Czech Republic over the course of the 1996–2010 time period through the use of a time-varying parameters Bayesian vector autoregression model with stochastic volatility. We evaluate whether the response of GDP and the price level to exchange rate or interest rate shocks has changed over time, focusing on the period of the recent financial crisis. Our results suggest that prices have become increasingly responsive to monetary policy shocks. However, in terms of credible intervals, the stability of the monetary policy transmission mechanism in the Czech Republic cannot be rejected. Furthermore, it is demonstrated that the exchange rate pass-through has largely remained stable over time.     

Granger Causality Between Money and Income for the Japanese Economy in the Presence of a Structural Change

This paper examines Granger causality between money and income in the Japanese economy based upon a bivariate VAR model with a structural change in the trend function. We employ a stratified testing strategy incorporating preliminary tests for a unit root and for the order of cointegration rank. Our study reveals that the choice of either trend stationarity or difference stationarity, as well as the order of cointegration rank, crucially affect the test results for Granger causality. It is found that the causality from money to income was strong before 1980 but weakened or virtually disappeared after 1980; the opposite causality existed weakly before 1980 but not after 1980. The result confirms the claim by the Bank of Japan (1992) and Honda et al . (1995) among others that the role of money as a leading indicator for predicting movements in income has weakened or even disappeared in the 1980s.
