Monetary risk measures for stochastic processes via Orlicz duality

Decisions in Economics and Finance - In this article, we extend the framework of monetary risk measures for stochastic processes to account for heavy tailed distributions of random cash flows...     

R&D contribution in TFP growth of Greek industry: A limited information likelihood approach

We provide a novel panel model to decompose total factor productivity (TFP) growth in the Greek industry at the firm level while we tackle the contribution of R&D. We, therefore, opt for parametric methodology that provides statistical inference and would validate the results. Our modeling departs from prior strong assumptions such as error terms across firms being independent. In fact, we provide a novel limited information maximum likelihood (LIML) estimation method that adequately deals with the issue of endogeneity and model misspecification. We demonstrate that our model detects variability in terms of TFP growth components across industries and firms. Our results show that R&D would enhance TFP of Greek firms, albeit the crisis has had a detrimental impact. Financial ratios such as liquidity and solvency ratios also affect TFP as we demonstrate that both would enhance TFP. The solvency ratio is important as it provides an estimate of whether the firm can cope with debt. We also note variability across small versus medium and large firms and report that small firms are more productive and spend more of their revenues on R&D. In terms of policy, our evidence warrants higher R&D spending to enhance TFP growth, though R&D funding is a concern.     

Influences of family ownership on dividend policy under mandatory dividend rules

The LIBOR manipulation scandal of 2008 spurred extensive policy debates regarding the importance of market-based reference rates. The alternative reference rates committee (ARRC) eventually identified the secured overnight financing rate (SOFR) to be a suitable replacement to LIBOR. In this study, we question the underlying process behind the choice of SOFR as a replacement for LIBOR. Both academic literature and regulatory bodies fail to identify a consistent definition and criteria of a good reference rate. We fill in this gap in the literature by providing an empirically testable ‘checklist’ to evaluate any potential money market rate to gauge its suitability as a reference rate. We also carry out an empirical evaluation of various money market rates against our criteria and identify the 1-month AA non-financial commercial paper rate as the best available replacement for LIBOR.

     

Human capital,innovation, and growth

This paper explores the interaction between human capital and innovation in the process of economic growth. Using a model of endogenous growth, we focus on how taxes and other policy instruments affect the incentives to invest in human capital. In contrast to many other growth models we find that the taxation of human capital has a substantial negative effect on its accumulation. This in turn reduces innovation and, consequently, the income growth rate. More surprisingly, other policies that are intended to stimulate growth may have opposing effects on innovation and the accumulation of human capital. For example, while subsidies to research and to intermediate inputs do have positive effects on innovation and growth, they lead to a lower stock of human capital, in the empirically relevant case when the elasticity of intertemporal substitution in consumption is low.
