Summary of previous work

• Weekly collection of data since mid May 2016

• Scraping of two biggest job portals (cover up to 95 % of

the market)

• Scraping of enterprise web sides (reference day only)

• Tools: Agenty (Feb17 – ), Import.IO (May16 – Jan17);

Python‘s Scrapy

• Record linkage with Slovenian Business Register (task

completed; 98 % data are linked).

• First estimates of coverage: about 50% of JV are

missing

Meetings with third parties – part 1

• December 2016: Employment Service of Slovenia (ESS)

– Aim: deeper knowledge about cooperation between enterprises

and ESS

• April 2017: meetings with private Employment agencies

– Problem: many ads, but client unknown

– 12/2 responded to the invitation

– One offered to report data on economic activities of a client and

on number of job vacancies per job ad.

Meetings with third parties – part 2

• May and June 2017: meetings with companies, owning

job portals

• Moja Zaposlitev:

– Problem1: poor comunication when creating draft of the contract

– Problem2: 45eur bill for paying company‘s lawer

– Contract was signed in July

– We offered them to analyse unstructured part of the job ad

• Moje Delo:

– Offered to send us full dataset of job ads

– Offered to implement a special filed for number of vacancies per

job ad

Survey about modes of JV advertising

• Aim: get information where do employers post JV ads

• Evaluation questionnaire was sent to units selected in

the current sample

• It was sent after the first reference point of regular

survey

• The main question in the questionnaire was:

“Do you usually advertise the JV ads by yourself or

you employ specialised agency?”

Survey about modes of JV advertising

• For those units which answered “by yourself” the

subsequent question was:

• “What channels you usually use for advertising JV?”

– Job portals

– Employment agency of the Republic of Slovenia

– Agencies (e.g. Manpower, Adecco, Trenkwalder …)

– Own website

– Facebook

– Other social media websites (LinkedIn, Twitter…)

– In the press

– Other

Survey about modes of JV advertising

• Around 95% of reported data come from units which

advertise JVs trough job portals and (or) Employment

• If we take into account also agencies (Trenkwalder …)

this percentage decreases additionally.

Time gap between job ad and

employment

• A job vacancy (JV) is defined as a post (which has been

newly created, is unoccupied or will shortly become

free) for which the employer is actively seeking a

suitable candidate outside the enterprise and which will

be filled immediately or in the near future.

• Start work: data on registration, changes and

deregistration for compulsory insurance (i.e. M-forms;

administrative source for the Statistical Register of

Employment).

• impossible to link M-forms with JVads from job portals.

• M-forms contain ad code for the ads from ESS
