We analyze the stochastic properties of three measures of profitability, return on assets (ROA), return on equity (ROE), and return on investment (ROI), using a balanced panel of US firms during the period 2001-2010. We employ a panel unit-root approach, which assists in identifying competitive...

We employ a dynamic adjustment model (Flannery and Rangan, 2006) to investigate the determinants of capital structure and speed of adjustment (Drobetz and Wanzenried, 2006) in a panel of 85 U.S. ICT firms over the years 1990 to 2013. We estimate the capital structure using a wide range of...

This paper empirically investigates firm-specific determinants of agency costs, a relatively new and unexplored area in corporate finance. We estimate dynamic agency costs models, linking debt, firm size, and R&D activity to agency costs for a panel of U.S. information and communication...

This paper proposes an empirical framework to estimate Okun's law which focuses on structural breaks and threshold nonlinearity. We use sequentially the Bai and Perron's (1998, 2003) structural break and threshold methodology to enable regime-dependent as well as threshold-dependent changes in...

This paper explores the dynamic linkages that portray different facets of the joint probability distribution of stock market returns in NAFTA (i.e., Canada, Mexico, and the US). Our examination of interactions of the NAFTA stock markets considers three issues. First, we examine the long-run...

We investigate inflation persistence in six inflation targeting (IT) countries from the global-economy perspective. This view maintains that inflation persistence in IT countries has declined mainly because of the decline of inflation persistence in the global economy. We provide empirical...

We propose a new long-memory model with a time-varying fractional integration parameter, evolving non-linearly according to a Logistic Smooth Transition Autoregressive (LSTAR) specification. To estimate the time-varying fractional integration parameter, we implement a method based on the wavelet...

This paper reports a two-stage analysis of inflation persistence using monthly data from 11 IT countries and, for comparison, the US, a non IT country with a history of credible monetary policy. First, we estimate inflation persistence in a rolling-window fractional integration setting using the...

This paper provides a new and unique look at the dynamics and persistence of historical house prices in the US and the UK using fractional integration techniques not previously applied to housing markets. We use annual data from 1830 to 2016 for the US and 1845 to 2016 for the UK, which provides...

This paper estimates the complete historical US price data by employing a relatively new statistical methodology based on long memory. We consider, in addition to the standard case, the possibility of nonlinearities in the form of nonlinear deterministic trends as well as the possibility that...
