We examine the (potentially nonlinear) relationship between inequality and growth using a method which does not require an a priori assumption on the underlying functional form. This approach reveals a plateau completely missed by commonly used (nonlinear) parametric approaches—the economy...

Using US manufacturing industry data, we re-examine evidence of first- and second-generation models of R&D-based endogenous growth focusing on innovation (patent) quality. We show that Schumpeterian growth theories perform better than semi-endogenous growth models.

In this paper we consider the problem of interpreting the signs of the estimated coefficients in multivariate time series regressions where the regressors are correlated. Using a continuous time model, we argue that focusing on the signs of individual coefficients in such regressions could be...

We investigate the directional accuracy of GDP and price forecasts by the Japanese government and the IMF with a new method developed by Pesaran and Timmermann [Pesaran, M.H., Timmermann, A., 2009. Testing dependence among serially correlated multi-category variables. Journal of the American...

Two-step estimation with large panel data sets generally involves estimating vectors of individual-specific coefficients in a first-stage. In a second-stage estimation a vector of estimated coefficients is used as the dependent variable. Potential problems of heteroskedasticity in the second...

Exchange rate arrangements and trade are inherently connected. Exchange rate volatility has a significant impact on trade volumes, and trading partners thus could affect each other’s exchange rate regime choice. This spatial effect among trading partners has been overlooked in empirical...

This paper applies the new procedure developed by Bai and Ng (2006a) to explore the relation between the Fama–French factors and the latent risk factors in China’s stock market. The results show that the Fama–French factors are good proxies for risk factors of portfolios. For individual...

We estimate three different models of speculative behaviour using oil price data. Our findings provide support for the claim by Phillips and Yu (2011) and Gilbert (2010) that a bubble in oil prices existed for a short period in 2008.

This study adopts the CoVaR methodology to analyse the tail risk relationships among European sovereigns, which provide arguably important information for policymakers to identify countries that should come under close scrutiny during the current debt crisis.

A Wald type test of the joint null hypothesis of linearity and nonstationarity within a threshold autoregressive process of order one with deterministic components is developed. Its limiting distribution is derived and its local power and finite sample properties investigated.
