How did the preferences of interest groups shape the design and contentiousness of crisis policies in deficit countries? And how did external actors influence their crisis responses? This chapter investigates these questions by drawing on a wealth of primary and secondary sources including newspaper coverage, voter public opinion data, interest group position papers, sovereign bailout documentation, and original qualitative evidence from seventeen in-depth interviews with national interest group representatives in Ireland, Spain, and Greece. There was a large consensus among both interest groups and voters across all three countries that external adjustment—that is, unilateral euro exit—should be avoided at all cost. This left financing and internal adjustment as the only options, and significant conflicts flared up in all three countries about how the costs associated with internal adjustment (and to a lesser extent financing) should be distributed. Within the confines set by the Troika, which effectively narrowed down the range of options available to deficit countries, interest groups pushed for reforms to which they were least vulnerable. Business interests, for example, generally supported adopting comprehensive spending-based consolidation measures and labor market reform. Conversely, labor unions and social policy groups actively supported policies that would entail stronger burden-sharing between firms and workers. Overall, internal adjustment policies adopted across all three cases generally reflected the preferences of employer associations more than those of workers, but especially in Spain and Greece, this was associated with considerable political upheaval.
