Do Formal Intellectual Property Rights Hinder the Free Flow of Scientific Knowledge? An Empirical Test of the Anti-Commons Hypothesis

Murray, Fiona - 2005

While the potential for intellectual property rights to inhibit the diffusion of scientific knowledge is at the heart … this debate is how intellectual property rights over a given piece of knowledge affects the propensity of future … researchers to build upon that knowledge in their own scientific research activities. This article frames this debate around the …

Intellectual Property Rights, the Pool of Knowledge, and Innovation

Stiglitz, Joseph E. - 2014

The pace of innovation is related both to the level of investment in innovation and the pool of knowledge from which … innovators can draw. Both of these are endogenous: Investments in innovations are affected by the pool of knowledge and the …

Tech Clusters

Kerr, William R. - 2020

Tech clusters like Silicon Valley play a central role for modern innovation, business competitiveness, and economic performance. This paper reviews what constitutes a tech cluster, how they function internally, and the degree to which policy makers can purposefully foster them. We describe the...

Industrial Clusters, Networks and Resilience to the Covid-19 Shock in China

Dai, Ruochen - 2020

We examine how exposure of Chinese firms to the Covid-19 shock varied with a cluster index (measuring spatial agglomeration of firms in related industries) at the county level. Two data sources are used: entry flows of newly registered firms in the entire country, and an entrepreneur survey...

Informational Content of Factor Structures in Simultaneous Binary Response Models

Khan, Shakeeb; Maurel, Arnaud; Zhang, Yichong - National Bureau of Economic Research - 2021

We study the informational content of factor structures in discrete triangular systems. Factor structures have been employed in a variety of settings in cross sectional and panel data models, and in this paper we formally quantify their identifying power in a bivariate system often employed in...

Clustering, Spatial Correlations and Randomization Inference

Barrios, Thomas - 2010

It is standard practice in empirical work to allow for clustering in the error covariance matrix if the explanatory variables of interest vary at a more aggregate level than the units of observation. Often, however, the structure of the error covariance matrix is more complex, with correlations...

Bootstrap-Based Improvements for Inference with Clustered Errors

Cameron, A. Colin - 2007

Researchers have increasingly realized the need to account for within-group dependence in estimating standard errors of regression parameter estimates. The usual solution is to calculate cluster-robust standard errors that permit heteroskedasticity and within-cluster error correlation, but...

Robust Inference with Multi-way Clustering

Cameron, A. Colin - 2006

In this paper we propose a new variance estimator for OLS as well as for nonlinear estimators such as logit, probit and GMM, that provcides cluster-robust inference when there is two-way or multi-way clustering that is non-nested. The variance estimator extends the standard cluster-robust...

Disability policies : Reform strategies in a comparative perspective

Böheim, René - 2016

We analyze different disability policy strategies using policy scores developed by the OECD for the period 1990 to 2007. Applying model-based and hierarchical agglomerative clustering, we investigate the existence of distinct country clusters, characterized by particular policy combinations. In...

Defining Clusters of Related Industries

Delgado, Mercedes - 2014

Clusters are geographic concentrations of industries related by knowledge, skills, inputs, demand, and/or other …
