Higher-order kernel semiparametric M-estimation of long memory

Robinson, Peter; Henry, Marc - London School of Economics (LSE) - 2002

estimating the memory parameter can avoid bias incurred by misspecification of the short memory component. We introduce a broad … to a smooth interpolation of asymptotic variances. The bias of these two estimates also differs to higher order, and we … also show how bias, and asymptotic mean square error, can be reduced, across the class of estimates studied, by means of a …

Non-response biases in surveys of schoolchildren: the case of the English Programme for International Student Assessment (PISA) samples

Micklewright, John; Schnepf, Sylke; Skinner, Chris J. - London School of Economics (LSE) - 2012

We analyse response patterns to an important survey of schoolchildren, exploiting rich auxiliary information on respondents' and non-respondents' cognitive ability that is correlated both with response and the learning achievement that the survey aims to measure. The survey is the Programme for...

Is network meta-analysis as valid as standard pairwise meta-analysis? It all depends on the distribution of effect modifiers

Jansen, Jeroen P.; Naci, Huseyin - London School of Economics (LSE) - 2013

Background In the last decade, network meta-analysis of randomized controlled trials has been introduced as an extension of pairwise meta-analysis. The advantage of network meta-analysis over standard pairwise meta-analysis is that it facilitates indirect comparisons of multiple interventions...

Galasso, Alberto; Schankerman, Mark - London School of Economics (LSE) - 2013

Cumulative innovation is central to economic growth. Do patent rights facilitate or impede such follow-on innovation? This paper studies the effect of removing patent protection through court invalidation on the subsequent research related to the focal patent, as measured by later citations. We...

Patent thickets and the market for innovation: evidence from settlement of patent disputes

Galasso, Alberto; Schankerman, Mark - London School of Economics (LSE) - 2008

We study how fragmentation of patent rights (‘patent thickets’) and the formation of the Court of Appeal for the Federal Circuit (CAFC) affected the duration of patent disputes, and thus the speed of technology diffusion through licensing. We develop a model of patent litigation which...

Enforcing intellectual property rights

Olson Lanjouw, Jean; Schankerman, Mark - London School of Economics (LSE) - 2001

We study the determinants of patent suits and their outcomes over the period 1978- 1999 by linking detailed information from the U.S. patent office, the federal court system, and industry sources. The probability of being involved in a suit is heterogeneous, being much higher for valuable...

Productivity dispersion, competition and productivity measurement

Martin, Ralf - London School of Economics (LSE) - 2008

A startling fact of firm level productivity analysis is the large and persistent differences in both labour productivity and total factor productivity (TFP) between firms in narrowly defined sectoral classes. The competitiveness of an industry is potentially an important factor explaining this...

Productivity spreads, market power spreads and trade

Martin, Ralf - London School of Economics (LSE) - 2010

Much of recent Trade theory focuses on heterogeneity of firms and the differential impacttrade policy might have on firms with different levels of productivity. A common problem isthat most firm level dataset do not contain information on output prices of firms which makesit difficult to...
