WP10 Objectives
• Integrate (existing) micro measures of within industry firm-level distributions with the EU-KLEMS data.
• Conduct empirical work using the augmented EU KLEMS data to explore recent theoretical models linking growth to firm dynamics and heterogeneity.
• Facilitate the analysis of productivity in work package 9 on technology and innovation by providing firm-level data
• Investigate potential to use firm level data in future updates of EU KLEMS Productivity Database.
EUKLEMS+: Integrating micro indicators
• Concordance are done• Firm-level indicators are being
documented/organized. • Looking for pilot-projects: EUKLEMS+
• Transition economies and Turkey (Bartelsman&Scarpetta)
• WP9 ???• Labor market flexibility
Links with WP 9
• WP10 access to micro data may provide indicators for WP9
• We may consider using expertise built up in:• OECD - micro innovation project• Eurostat/ONS ICT-firm performance project.
This project uses linked micro datasets (PS, Ecommerce, R&D) and infrastructure at NSOs. Also EUKLEMS industry hierarchy is used.
Micro-data for updating EUKLEMS• Many indicators, especially those outside of
SNA framework, may be collected directly from linked micro datasets using distributed micro data analysis.• Labor quality• Investment by industry/asset
• Harmonized approach can coordinate technical details, eg sample reweighting.
• An inventory of available sources and metadata needs to be made• Volunteer: someone with overview of WP2/3

Cross Country Differences in Productivity: The Role of Allocative Efficiency
Overview• Healthy, market economies exhibit the following features at the
firm level:• Large dispersion of productivity across firms within narrowly
defined sectors.• Must be due to some form of “friction”
• Market power• Economies of scope/decreasing returns• Adjustment frictions and idiosyncratic shocks:
• Search and matching frictions• Labor and capital adjustment costs• Entry and exit costs
• Strong positive covariance between market share and productivity• Static allocative efficiency
• Market selection is productivity enhancing• Market selection yields exit of less productive firms and
establishments• High pace of input (e.g. jobs) and output reallocation
• Uncertainty, experimentation, learning and selection as well as time varying idiosyncratic shocks
Distortions and Allocative Efficiency?• Working conjecture:
• Emerging and transition economies have market structure and institutions that distort allocative efficiency
• Distortions:• Imperfect competition• Subsidies (explicit) or quotas/rationing of allocation to
insiders/incumbents/favored businesses• Credit constraints to young and small businesses• Bribes and corruption (unevenly applied)• Doing Business inefficiencies:
• Costly to start up a business• Costly to adjust employment• Poor or inefficient infrastructure (telephones, roads, electricity)
• Key point: Distortions have idiosyncratic component: cross-sectional allocation is distorted
• Entry barriers act in this way naturally• Credit constraints for young and small businesses• Arbitrary and capricious application of regulations
Aggregate productivity and allocation
• Olley and Pakes (1996) static decomposition:
where: N: # of firms in a sector; The first term is the unweighted average of firm-level productivityThe second term (OP cross term) reflects allocation of resources: do firms with
higher productivity have greater market share.Requires representative cross sectional samples but does not require accurate
longitudinal linkagesCannot quantify directly importance of entry and exit
By construction, cross term takes out country effects in productivity levels, so abstracts from some aspects of measurement error

Consumers supply labor inelastically and maximize utility:
Firms maximize profits:•Ex ante firms do not know productivity or distortion but know distribution. •Pay entry fee, learn their draws, decide whether to produce.•Productivity and distortion draws are firm-specific and time invariant•Very low productivity/high distortion firms don’t produce•Decreasing returns yields dispersion in productivity/distortions•Overhead labor yields correlation between TFP and LP

Relationship Between Productivity and Employment: No Distortions
Relationship Between Labor Productivity and Employment (Random distortion case)
Observations
• Distortions affect various margins• Entry: amount and characteristics• Allocation among survivors• OP cross term reflects allocation for given survivors
• Uncorrelated scale distortion• Slight increase in mean TFP/LP
• Lower survival
• Lower OP cross term for both TFP and LP• Affects entry and selection• Lower consumption (C) through lower productivity
and excess churn
Observations (2)
• Uncorrelated factor-mix distortion• Slight increase in Mean TFP and LP again
• Lower survival• Not much impact on OP cross term for either TFP and LP• K/L too high• Lower C primarily through distorted high capital investment
• Correlated scale distortion• Mean TFP/LP much lower• OP cross term very low• Adverse impact on survival• So: wrong firms survive, allocation poor amongst survivors
and too much churn (everything wrong!)• Much lower C from all of these factors
Open questions
• Can we account for differences across countries in productivity via the distribution of distortions?• If so, what are these distortions?
• Static vs. Dynamic distortions?• Is wedge between marginal product and factor prices because
of adjustment costs (dynamic) or a more permanent distortion (e.g., favored businesses)
• Can we quantify the reduction in distortions in transition economies that account for rising allocative efficiency?
• Implications for growth: transition dynamics vs. steady state growth?
• Missing pieces (many):• E.g., Differentiated products version of model• More frictions? (Experimentation/learning/adjustment costs)
