Past Research Seminars

Below is a list of past research seminars hosted by POID featuring our academics and researchers at LSE.

6 September 2021 - Social Push and the Direction of Innovation
Speaker: Xavier Jaravel
Location: LSE (online)
Innovators' personal experience and social networks may affect their familiarity with customer needs, and in turn the types of products they bring to market. Consistent with this channel, we document that innovators create products that are more likely to be purchased by customers similar to them along observable dimensions including gender, age, and socio-economic status.

5 July 2021 - Has aggregate productivity and pay decoupled the UK?
Speakers: Andreas Teichgraeber (and John Van Reenen)
Location: LSE (online)
This presentation analysed the growth of productivity and pay in the UK over the last 40 years. We showed that mean employee compensation and labour productivity have both almost doubled. However, when extending the analysis to the self-employed, we found a 60 percentage point difference in growth rates of employee and self-employed income between 1980 and 2019. This difference almost entirely explains the slight fall in the UK's labour share of GDP over that time period. If we further exclude non-wage compensation elements from the labour share, we found an even bigger fall (over five percentage points).

7 June 2021 - Globalization and market power
Speaker: Gianmmario Impullitti
Location: LSE (online)

10 May 2021 - Supersize Me: intangibles and industry concentration
Speaker: Matej Bajgar (and Chiara Criscuolo)
Location: LSE (online)
The presentation offered new evidence on the growing scale of big businesses in the United States, Japan and 11 European countries since the early 2000s. The rising concentration is strongly associated with intensive investment in intangibles, particularly innovative assets, software and data, and this relationship is stronger in more globalised and digital-intensive industries.

21 April 2021 - Induced innovation, inventors, and the energy transition
Speaker: Eugene Dugoua
Location: LSE (online)

1 March 2021 - UK prices - a new firm-level data set
Speaker: Richard Davies
Location: LSE (online)
This presenation exposed a new dataset of 41 million UK consumer prices, providing facts on the frequency, size and timing of price changes between 1988 and 2020. The micro data are the 'price quotes' of individual consumer products that make up the official Consumer Prices Index (CPI) for the UK. Prices are recorded between January 1988 and December 2020 and cover a wide-ranging selection of items including food and drink, homewares, furniture and appliances, motoring supplies and fuels as well as a range of services.

1 February 2021 - The Empirics of 'Blitzscaling': technology and high-growth firms in the UK
Speakers: Mirko Draca (and Anna Valero)
Location: LSE (online)

11 January 2021 - The long-term productivity effects of working from home
Speaker: Jonathan Haskel
Location: LSE (online)
The COVID-19 pandemic caused a widespread decline in recorded GDP. Yet, as catastrophic as the collapse was, it was buffered by an unprecedented and spontaneous deployment of what we call "Potential Capital", the dwelling/residential capital and connective technologies that enabled some (fortunate) workers to work from home. We estimate the contribution of this capital, and the work from home that it facilitated, to have roughly halved the decline in GDP in the US reducing the fall in GDP to 9.4 percentage points in 2020Q2 at the trough of the recession. Turning to the future, changes in working from home depend upon relative costs, relative technologies and, crucially, the elasticity of substitution between home and work tasks. We estimate that that elasticity to be more than unity and suggest that the growth of ICT will raise the share of work done from home.

7 December 2020 - Competition and pass-through: evidence from the isolated markets
Speaker: Christos Genakos
Location: LSE (online)
This presentation demonstrated how pass-through varies with competition in isolated oligopolistic markets with captive consumers. Using daily pricing data from gas stations, we studied how unanticipated and exogenous changes in excise duties (which vary across different petroleum products) are passed through to consumers in markets with different numbers of retailers. We found that pass-through increased from 0.4 in monopoly markets to 1 in markets with four or more competitors and remained constant thereafter.

2 November 2020 - Industrial policy, clean growth and COVID-19
Speaker: Ralf Martin
Location: LSE (online)

5 October 2020 - Overview of POID work programme
Speaker: John Van Reenen
Location: LSE (online)
