Channels of Labour Supply Responses of Lone Parents to Changed Work Incentives In this paper, we investigate the response of female lone parents to two reforms to the welfare system in Australia. We look at changes to both hours and participation and focus on the channels of adjustment, in particular the role of job changes for adjustment in hours. We highlight the relationship between policy d...

This paper presents a brief summary of classical statistical inference for many commonly-used regression model estimators that are asymptotically normally distributed. The paper covers Wald con…dence intervals and hypothesis tests based on robust standard errors; tests of model adequacy and model diagnostics; family-wise error rates and false discovery rates that control for multiple testing; a...

Stability tests for cointegrating coefficients are known to have very low power with small to medium sample sizes. In this paper we propose to solve this problem by extending the tests to dependent cointegrated panels through the stationary bootstrap. Simulation evidence shows that the proposed panel tests improve considerably on asymptotic tests applied to individual series. As an empirical il...

Using the Helmert-Transformation to Reduce Dimensionality in a Mixed Model: Application to a Wage Equation with Worker and Firm Heterogeneity A model for matched data with two types of unobserved heterogeneity is considered – one related to the observation unit, the other to units to which the observation units are matched. One or both of the unobserved components are assumed to be random. This...

The standard LM tests for spatial dependence in linear and panel regressions are derived under the normality and homoskedasticity assumptions of the regression disturbances. Hence, they may not be robust against non-normality or heteroskedasticity of the disturbances. Following Born and Breitung (2011), we introduce general methods to modify the standard LM tests so that they become robust agai...

Price dynamics in Indian cities were examined using cointegration analysis. We identified and calculated a common trend for prices in 25 major cities in India. Impulse response functions were obtained to calculate the rates of convergence to the prices and we found that the half-life of any shock is very small for Indian cities. Although a close to three-month half-life seems too fast, there is...

We propose a novel estimator for the amount of international risk sharing that depends exclusively on asset returns data. In particular, our estimator has a nonparametric flavor in that it makes no parametric assumption on preferences and on the stochastic process that governs the dynamics of asset returns. This is in contrast with the existing estimators in the literature that either assume a ...

To what extent can exporters cushion the impact of currency appreciation shocks by using imported intermediates? We apply a partial equilibrium model with heterogeneous firms. Producers can serve the domestic market, export final goods, or import inputs. In the model, an exogenous exchange rate shock simultaneously affects the variable costs and revenues associated with exports and imports. The...

We examine cross-region capital mobility in China and track how the degree of mobility has changed over time. The effects of fiscal and redistributive activities of different levels of government in China on private capital mobility are taken into account. Our results indicate that there is a significant improvement in capital mobility over time in China, particularly for private capital in the...

Ornstein-Uhlenbeck models are continuous-time processes which have broad applications in finance as, e.g., volatility processes in stochastic volatility models or spread models in spread options and pairs trading. The paper presents a least squares estimator for the model parameter in a multivariate Ornstein-Uhlenbeck model driven by a multivariate regularly varying Lévy process with infinite v...
