This study investigates the causal relationship between human capital inequality and income inequality in case of Pakistan. The annual time series data ranging from 1973 to 2009 is used for econometric analysis. Johanson co-integration and Granger Causality tests are used to confirm the existence of long run relationship and the causal relationship between human capital inequality and income inequality. The results indicate that there is positive relationship between the two types of inequalities in the long run. The estimates of causality test indicate that income inequality causes the human capital inequality but human capital inequality does not cause income inequality. Policy initiatives to reduce income inequality may empower people economically to avail skill building opportunities and accumulate their human capital through access to educational services. 相似文献

Trust is essential for the success of change, but transformational change challenges trust. This paper analyses how trust dynamics develop over time in two Danish manufacturing firms affected by major change programmes. The results show that change creates uncertainty among employees, thereby provoking intense scrutiny of management intentions and a tendency to make interpretations that exaggerate management intentions—with the end result of reduced trust. Management then react similarly with negative interpretations of employee reactions, creating a vicious cycle of reduced trust. The paper proposes a model for how change and trust interact and suggests a managerial strategy for trust repair: Strong management actions that symbolise integrity, competence and benevolence may counteract reduced trust, but if low trust turns into distrust, the result may be a deadlock that both parties find difficult to break. 相似文献

We point out that fiscal multipliers derived from SVAR-models include the predicted future path of policy instruments. After the initial shock, net taxes and government expenditures react to each other and are autocorrelated. In a counterfactual simulation, we report fiscal multipliers that abstract from these dynamic responses. 相似文献

We consider forecasting the term structure of interest rates with the assumption that factors driving the yield curve are stationary around a slowly time‐varying mean or ‘shifting endpoint’. The shifting endpoints are captured using either (i) time series methods (exponential smoothing) or (ii) long‐range survey forecasts of either interest rates or inflation and output growth, or (iii) exponentially smoothed realizations of these macro variables. Allowing for shifting endpoints in yield curve factors provides substantial and significant gains in out‐of‐sample predictive accuracy, relative to stationary and random walk benchmarks. Forecast improvements are largest for long‐maturity interest rates and for long‐horizon forecasts. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

This paper resolves two issues regarding the traditional capital asset pricing model with one risk-free asset which seem to
have been overlooked in the literature. First, it provides an elementary and complete proof of the two-fund separation theorem
which accounts for the fact that asset demand may become undefined if the limiting slopes of the investor’s indifference curves
are finite. Second, it shows that an additional limiting condition on investors’ risk aversions is generally necessary to
guarantee existence of an equilibrium. Moreover, a generalized existence result is formulated which includes investors who
in equilibrium may not invest in risky assets and a simple condition ensuring positive equilibrium asset prices is given. 相似文献
