Introduction

One of our objectives is to quantify the nature of graduate labour market flows between the countries and regions of GB

Why bother?

•Not a great deal is known about this.

•Regional focus: Scotland, England and Wales

•export and import of graduates equally interesting as the export and import of goods and services

•Information along these lines will be fed into the CGE analysis

Policy Relevance

• Concern with depopulation of rural and remote regions of Scotland

• Migration flows of students and graduate thought to reinforce migration flows of general population (north and west to the east)

• “Belief” that building Higher and Further Education institutions in rural and remote regions will help reverse these trends

HESA (Higher Education Statistical Agency) is the official agency for the collection, analysis and dissemination of quantitative information about higher education in the UK.

We use two datasets:(1) Destinations of leavers from HEIs (DLHE)(1) Destinations of leavers from HEIs (DLHE)(2) Students in HEIs (2) Students in HEIs

12 waves available from 1994/95 to 2005/2006

For current analysis, we focus on the most recent wave (05/06) which includes information on around 2.4 million students and around 230,000 graduates.

DataData

A Brief Picture of HEIs in Scotland

20 HEIs: 8 pre-92 Universities, 6 post-92 Universities and 7 Colleges (mainly clustered around Glasgow and Edinburgh)

Total number of students in 05/06: 215, 820

Number of students went up by 44.9% between 94/95 and 05/06 (c.f. national average 49.1%; England 48.7%).

The HESA data provide three key postal addresses:

(1)Place of domiciledomicile(2)Place of studystudy(3)Place of employmentemployment

This allows us to identify 3 migration types3 migration types

Stayers, Interregional Movers V.S. LeaversTwo different movements studied here:

2. MEDIUM DISTANCE2. MEDIUM DISTANCE movements (interregional but within country) – interregional re-allocation of skilled labour

1.1.LONG DISTANCELONG DISTANCE movements (inter-country within GB) – ‘brain drain’

or ‘brain gain’?

flows (Model 2) of graduatesflows (Model 2) of graduates from and to

Scotland using a Multinomial Logit Model to

identify both problems of:

• Retention Retention of graduates within Scotland

(Model 1: stayers and interregional migrants)

• AttractionAttraction of graduates from outside

Conclusions and Future Work

Future workTo incorporate more variables on regional characteristics, e.g. quality of life, social/economic environment;

To use more disaggregated regions for analysis of England/Wales, e.g. NUTS2;

Check for consistency of results over time and/or time trends by incorporating longer time series in the analysis

Preliminary ConclusionsScotland is a ‘net-loser’ of graduates in absolute terms, but vis-à-vis elsewhere in GB, it attracts the largest % of high-quality graduates

Determinants of leavers similar from and to Scotland: male(+), age(-), Asian(-), postgraduate(+), 1st/2.1(+), science(+), combined(+), ex-polytech(-), college(-), and regional effects

Regional retention of human capital crucial: high-mobility graduates are of best quality
