Porter's 2001 'strategy and the Internet' paper is a key article in the field of on-line strategy. This paper assesses Porter's views in the light of current and past developments. Porter's paper, whilst still thought provoking in many ways, now shows some weaknesses, and in places is no longer...

This dissertation includes three essays on hedging the interest rate and credit risks of Mortgage-Backed Securities (MBS).Essay one addresses the problem of how to efficiently estimate interest rate sensitivity parameters of MBS. To do this in Monte Carlo simulation, we derive perturbation...

The underlying components of protection motivation theory (PMT; Rogers 1983) areexplored through choice experiment-based analysis within a random utility framework, toaccount for some of the motivational, cognitive, and affective processes that likely affectceliacs’ propensity to use a novel...

This study proposes a multi-dimension, multi-contingent "fit" perspective for examining different practices adapted by entrepreneurial firms in acquiring human resources. We posit that while environmental constraints are important considerations for adapting recruitment practices through...

Unlike the prediction of a frictionless open economy model, long-term average savings and investment rates are highly correlated across countries—a puzzle first identified by Feldstein and Horioka (1980). We quantitatively investigate the impact of two types of financial frictions on this...

This paper studies the famous Feldstein and Horioka finding, which is a high correla-tion between long period averages of savings rates and investment rates across countries. We first confirm the Feldstein-Horioka finding with a more recent data set, and then show that a calibrated complete...

This thesis includes four empirical studies related to foreign direct investment (FDI), governance, economic growth and the environment. We firstly investigate the existence of the so called pollution haven hypothesis (PHH) in China, i.e. the impact of regional environmental regulations (ER) on...

While earlier empirical studies found a negative saving effect of old-age dependency rates without considering longevity, recent studies have found that longevity has a positive effect on growth without considering old-age dependency rates. In this paper, we first justify the related yet...

Generalized likelihood ratio statistics have been proposed in Fan, Zhang and Zhang [Ann. Statist. 29 (2001) 153-193] as a generally applicable method for testing norparametic hypotheses about nonparametric functions. The likelihood ratio statistics are constructed based on the assumption that...

Likelihood ratio theory has had tremendous success in parametric inference, due to the fundamental theory of Wilks. Yet, there is no general applicable approach for nonparametric inferences based on function estimation. Maximum likelihood ratio test statistics in general may not exist in...
