How do firms use fixed-term contracts?

This paper examines how Italian firms use fixed-term contracts (FTCs) and documents the relative importance of seasonal needs, worker screening and buffer-stock motives. Using matched employer–employee data for 2013–2017 merged with firm-level balance-sheet information, we select a set of firms that systematically rely on temporary employment, generating over 85 per cent of its total volume. By focusing on these firms, we show that two ex ante contract features - the seasonal label and the initial duration - are highly informative about firms' hiring intentions. Use of seasonal contracts is limited and concentrated in a narrow set of sectors, while longer initial durations strongly predict conversion into permanent jobs, reflecting screening behaviour driven mainly by firm-specific factors. In contrast, most FTCs are short, non-seasonal and concentrated in firms dealing with lower productivity and higher revenue volatility, consistent with buffer-stock adjustment. A clustering exercise confirms that about 10 per cent of firms predominantly use seasonal contracts, one fourth use FTCs for screening, and roughly 65 per cent rely on them to manage uncertainty.
