Introduction

• Global Economy faces socioeconomic challenges • Existing linear ‘take-make-dispose’ models of economic growth

are unsustainable • A solution? Combine the ‘old’ with the ‘new’

• Usage of renewable resources from the earth combined with state-of-the-art 21st century technologies ≈ ‘Circular Economy’

• BioEconomy –18.6 million jobs, 2.2 billion euros turnover.

• How to optimise biomass (food, feed, energy, industrial) to make a meaningful contribution to the notion of a circular economy

• Governing principle : ‘Cascading hypothesis’

Study Context

• Within this broad policy debate, this study focuses on the following research questions: • Can we identify structural mechanisms or linkages to

measure the wealth generating potential of bio based activities within the EU macro-economy?

• Can we identify ‘typical’ structural patterns across the Member States?

• What is the employment generation potential of each of the bio based sectors?

• Are there any standout performers amongst the bio based sectors?

• Very few quantitative economy-wide studies to tackle these

questions. • Reason? data driven

SAM Data

• Social Accounting Matrices (SAM)

• JRC published the EU-27 (AgroSAMs) for year 2000 (Muller et al., 2008) constructed by MS. Applied to Spain (Cardenete et al., 2012).

• Updated “AgroSAMs” for 2007 (Philippidis et al., 2014) employing Eurostat data and GDP target data. Applied to the EU27

• Current study follows these precedents. Constructs 28 EU MS SAMs for the year 2010. AgroSAM agricultural detail PLUS contemporary bio based sectors – “BioSAMs”

SAM Multipliers

In the SAM, inter-sectoral linkages create direct and indirect ripple effects, or multipliers: Demand driven (Backward Linkage, BL) - Agriculture uses industrial inputs like fertilizers, pesticides, machinery, energy etc. Supply driven (Forward Linkage, FL) - Agriculture supplies raw materials to agro-based industries

BL and FL multipliers are relative measures normalised to an index of 1. For example, if BL>1, intermediate input demand by sector j generates a higher than average wealth compared with other sectors in the economy Employment multipliers: Based on priors (000’s head) – indicates how rising output of activity j affects economy-wide (direct and indirect) employment.

Study Aims

• Profiling of EU28 bio based activities based on structural classification (i.e., multipliers) analysis and statistical clustering and means comparison tests.

• Four aims:

• Identify and classify EU clusters employing BL and FL multipliers as segmentation variables.

• Statistically profile EU clusters:

• Within cluster statistical tests to examine relative BL and FL multiplier strength of bio based sectors

• Across cluster statistical tests to identify the degree of heterogeneity/homogeneity of bio based sectors

• Calculate employment generation multiplier effects emanating from the bio based sectors

• Detect strategically important bio based sectors ('key sectors').

Statistical tests I

• Statistical (1% and 5%) one-way Anova tests across EU regional clusters to validate clustering and identify structural heterogeneity by sector (i.e., examine different levels of BL and/or FL wealth generation by sector across five EU clusters)

• Statistical heterogeneity of BLs wealth generation in 29 of the 32 biobased sectors (25 at 1% significance) across regional clusters.

• Statistical heterogeneity of FLs in 22 of the 32 (15 at 1% significance) bio based sectors across regional cluster

Statistical tests II

• Paired t-test between BL and FL multiplier means within clusters for each of the 32 bio based activities

• Statistically (1% and 5%) significant ‘backward orientation’ (i.e., BL higher than FL)

• 23 EU MS: ‘Mainly Eastern’ (31 sectors), ‘Mediterranean’ (28 sectors), ‘Northern & Central’ (21 sectors).

• 5 EU MS:’Isles&Lux’ (3 sectors), ‘Baltics’ (4 sectors)

• Highly diversified portfolio of inputs (feeds, fertiliser, energy, veterinary services, machinery, transport) - ripple effects throughout the economy.

• Limited supply driven (FL) multipliers – supply chain less diversified (smaller ripple effects)

• Consistent with previous work (Philippidis et al., 2014)

• Groups 1 and 4 (10+2 EU MS): Strong BL (@1.5) and weaker FL (especially Grp 1). More volatile (especially Baltic) wealth generation (‘moderate’ bio based cluster, 1 in 6 are key sectors)

• Group 2 (3 EU MS): Moderate BL (@0.8), weak FL (@0.4). Highly volatile wealth generation (‘weak’ bio based cluster, 1 key sector)

Key sectors

• Key sector definition: BL > 1 and FL > 1

• 30 examples of key sectors in 21 bio based sectors across the five EU clusters

• All five clusters: ‘raw milk’ (as in Philippidis et al., 2014)

• Four clusters: ‘intensive livestock’

• Three clusters: ‘cereals’, ‘animal feed’, ‘forestry’, ‘wood’ and ‘other food’

• NO key sectors in ‘new’ biobased sectors: 1G & 2G biofuels, bio-chemicals, bioelectricity, biomass from energy crops and pellets NONE are key, although bioelectricity has potential key sector status (BL > 1, [email protected]) in ‘Mainly Eastern’, ‘Baltic’ & ‘Mediterranean’ clusters (15 EU MS).

• Bio energy is consistently the lowest employment generator, although comparable with non bio based averages.

• Bio based vs. non bio based: former generates higher employment in all clusters.

• Primary agric. is key driver (‘Mainly Eastern’ and ‘Baltic’)

• ‘Mixed’ evidence of correlation between wealth and employment generation.

Conclusions I

• Caveat: Useful profiling of bio based economy within a consistent data framework – BUT 2010 structure of the economy and multipliers are short run indicators (no substitutability, no tech change)

16

• Employment generation in bio based higher (also in Philippidis et al., 2014).

• Careful: quality of labour issue not considered.

• Higher wealth: higher employment correlation: evidence mixed

• BL and FL (i.e, structural indicators) segmentation variables creates five distinct EU clusters

• Across EU clusters, BL (FL) wealth generation by sector is statistically heterogeneous in 29 (22) of 32 bio based sectors.

• Bio based wealth generation remains 'backward' orientated within each EU cluster. Consistent with Philippidis et al. (2014).

• ‘Mainly Eastern’ and ‘Mediterranean’ strong bio based activity.

• ‘Northern & Central’ and ‘Baltic’ moderate bio based activity

• ‘Isles & Lux’ weak bio based activity

17

• Key sectors ‘raw milk’ and ‘intensive livestock’ perform well (wealth and employment). Policy conflict: large non CO2 emitters

• Key Sector frequency higher than previous studies (Cardenete et al., 2012; Philippidis et al., 2014).

• Process of structural change between 2000, 2007 and 2010 possibly accelerated by the financial crisis.

• Bio based economy more resilient resulting in increased relative wealth generation (i.e., many more key sectors)

Conclusions II

• Cascading principle of a ‘last resort’ energy usage for biomass material

• Bioenergy has lower wealth and is lowest generator of employment generation in all bio based sectors.

• From an economists perspective, there is no opportunity cost of forgoing bioenergy applications for other biomass applications.

• This analysis does not enter into conflict with the cascading principle of biomass usage (based on 2010 economic structures)
