Entropy of Convex Functions on $$\mathbb {R}^d$$ R d

Constructive Approximation, 2017
Motivated by both theoretical reasons and concrete applications, the authors provide sharp estimates for the \(\varepsilon\)-entropy of the class of convex functions with \(L^r\)-norm bounded by 1 defined on a bounded solid closed convex subset of \(\mathbb{R}^d\) with respect to \(L^p\)-metrics (where \(1\leq p < r\)). Upper bounds for \(d\)-polytopes

Company R&D and University R&D - How Are They Related? [PDF]

, 2005
At the same time as we can observe strong tendencies of a globalisation of R&D, we also can observe a strong spatial clustering of R&D and related innovative activities. The standard explanation in the literature of the clustering of innovative activities is that such clusters offer external knowledge economies to innovative companies, since they are ...

The Range of Rademacher Series in $${\mathbb R}^d$$ R d

Results in Mathematics, 2019
For a sequence $(a_n)$ in $\mathbb R^d$ with $\lim_{n \to \infty} a_n = 0$ and $\sum_{n \in \mathbb N} \|a_n\| = \infty$ the author studies the Rademacher range of $(a_n)$, that is the set $\mathcal R(a_n)$ of those $x \in \mathbb R^d$ that have a representation of the form $x = \sum_{n=1}^\infty t_n a_n$ with $t_n = \pm 1$. A vector $v \in \mathbb R^d$

R&D, Innovation and Exporting [PDF]

, 2011
This study considers the determinants of whether a firm exports, undertakes R&D and/or innovates, and, in particular, the contemporaneous links between these variables using three waves of the UK Community Innovation Survey (CIS). Where appropriate, an instrumental variables procedure is employed to overcome problems of endogeneity.

Wage Inequality, R&D Labor and R&D Productivity [PDF]

Economics Bulletin, 2012
This paper examines the transitional dynamics of an R&D-based endogenous growth model with heterogeneous labor and explains the post-war comovement of three variables in the U.S. economy: the skill premium, the share of labor devoted to R&D and the growth rate of labor productivity. This paper provides a complete dynamic analysis of the model. We argue

The Impact of Participation in R&D Programs on R&D Partnerships

2005
Research and innovation partnerships involving firms or firms and public research organizations (PROs) have been increasing over the last twenty years in OECD countries. In this paper we present empirical evidence about the impact of government sponsored R&D programs on firms' partnership strategies related to R&D.

R&D and the Productivity Slowdown [PDF]

American Economic Review, 1980
The question I shall address in this pa-per is: Can the slowdown in productivity growth be explained, wholly or in part, by the recent slowdown in the growth of real R&D expenditures? But first we have to review the following questions: I) What is to be explained? Which productivity and what slowdown?
