European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Abstract
This article derives a European Herfindahl-Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity towards large and concentrated industries. Over the same period, productivity gains from reallocation accounted for 50% of European productivity growth and markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Globalisation in Europe: Consequences for the Business Environment and Future Patterns in Light of Covid-19
Sergio Inferrera
IWH-CompNet Discussion Papers,
No. 2,
2021
Abstract
In this paper, I study the consequences of globalisation, as measured by the involvement of firms in GVC, on the business environment. In particular, I focus on concentration and productivity, firstly by estimating robust elasticities and then isolating the exogenous component of the variation in the participation in GVC. To this aim, I exploit the distance between industries in terms of upstreamness and downstreamness along the supply chain. The evidences suggest that involvement in international supply chains is positively related to concentration at the sector level and positively associated with aggregate productivity, an effect that is driven by the firms at the top of the productivity distribution. Finally, I relate these findings to the current pandemic, going beyond the lack of official statistics and estimating GVC participation for 2020 at the country-level through real time world-seaborne trade data, providing evidences on the re-absorption of the Covid shock in several European economies.

Economy in East Germany shrank less than in the West, but will have weaker momentum when pandemic disappears – Implications of the Joint Economic Forecast Spring 2021 and new data for East Germany
At 3%, the increase in gross domestic product in eastern Germany in 2021 is likely to be lower than in Germany as a whole (3.7%), as the slump due to the pandemic was smaller in 2020. In the course of the economic recovery in the second half of the year, the unemployment rate is expected to fall slightly.

Pandemic delays upswing – Demography slows growth
In their spring report, the leading economic research institutes forecast an increase in gross domestic product of 3.7% in the current year and 3.9% in 2022. The renewed shutdown is delaying the economic recovery, but as soon as the risks of infection, particularly from vaccination, have been averted, a strong recovery will begin. The economy is likely to return to normal output levels around the start of the coming year.

Introduction to "Measuring and Accounting for Innovation in the Twenty-First Century"
Javier Miranda
Measuring and Accounting for Innovation in the Twenty-First Century,
NBER Studies in Income and Wealth, Vol 78 /
2021
Abstract
Measuring innovation is challenging both for researchers and for national statisticians, and it is increasingly important in light of the ongoing digital revolution. National accounts and many other economic statistics were designed before the emergence of the digital economy and the growing importance of intangible capital. They do not yet fully capture the wide range of innovative activity that is observed in modern economies. This volume examines how to measure innovation, track its effects on economic activity and prices, and understand how it has changed the structure of production processes, labor markets, and organizational form and operation in business. The contributors explore new approaches to, and data sources for, measurement—such as collecting data for a particular innovation as opposed to a firm, and the use of trademarks for tracking innovation. They also consider the connections between university-based R&D and business startups, and the potential impacts of innovation on income distribution. The research suggests potential strategies for expanding current measurement frameworks to better capture innovative activity, such as more detailed tracking of global value chains to identify innovation across time and space, and expanding the measurement of the GDP impacts of innovation in fields such as consumer content delivery and cloud computing.

Measuring the Impact of Household Innovation Using Administrative Data
Javier Miranda, Nikolas Zolas
Measuring and Accounting for Innovation in the Twenty-First Century,
NBER Studies in Income and Wealth, Vol 78 /
2021
Abstract
We link USPTO patent data to U.S. Census Bureau administrative records on individuals and firms. The combined dataset provides us with a directory of patenting household inventors as well as a time-series directory of self-employed businesses tied to household innovations. We describe the characteristics of household inventors by race, age, gender and U.S. origin, as well as the types of patented innovations pursued by these inventors. Business data allows us to highlight how patents shape the early life-cycle dynamics of nonemployer businesses. We find household innovators are disproportionately U.S. born, white and their age distribution has thicker tails relative to business innovators. Data shows there is a deficit of female and black inventors. Household inventors tend to work in consumer product areas compared to traditional business patents. While patented household innovations do not have the same impact of business innovations their uniqueness and impact remains surprisingly high. Back of the envelope calculations suggest patented household innovations granted between 2000 and 2011 might generate $5.0B in revenue (2000 dollars).

The East-West-German Productivity Gap: Lessons from Firm-level Data?

Konferenzband "30 Jahre Deutsche Einheit", März
2021
Abstract
According to national accounts, the East German economy is at only 80 % of West German labour productivity even 30 years after the fall of the Iron Curtain. This difference in aggregate labour productivity goes hand in hand with many of the economic and societal problems East Germany faces today. To understand the sources of the aggregate productivity gap, this study discusses recent literature on the East-West gap that applies granular firm and product level data. The evidence clearly shows the relevance of firm-level productivity differences for the aggregate gap and challenges common hypotheses derived from aggregate data.

30 Years after Reunification, Gross Domestic Product has Served its Purpose as an Indicator
Oliver Holtemöller
Wirtschaftsdienst,
Konferenzband "30 Jahre Deutsche Einheit", März
2021
Abstract
The comparison of living conditions in East and West Germany is often based on the gross domestic product per inhabitant. However, this measure is not a good welfare indicator in itself. It can be assumed that, measured by the gross domestic product per inhabitant, there will be no further significant equalisation of economic power in East and West Germany in the foreseeable future. This is because the age structure of East Germany, i.e. the ratio of employed persons to inhabitants, is less favourable than in the West. On the other hand, if one looks at important welfare indicators such as consumption opportunities, life expectancy, leisure time and income inequality, living conditions in East and West Germany are more similar than the gross domestic product per inhabitant suggests. In the debates on the catching-up process of East Germany, more emphasis should therefore be placed on labour productivity as a measure of economic strength and on welfare indicators as a measure of the equalisation of living conditions.
