Operating in the context of deregulated financial markets, credit rating agencies do not only 'provide an opinion', but also affect macroeconomic dynamics. By utilizing a twocountry stock flow consistent model that provides a representation of the Eurozone, the paper connects the movements of sovereign ratings with the dynamics of the financial market and the constraints on fiscal policy. With endogenous fiscal expenditure and an endogenous credit rating mechanism the model shows how following a recessionary shock, a rating downgrade can influence the financial constraints that surround a government, pushing it toward fiscal austerity and thereby deepening the already ongoing recession.
| IN TRO DUCT IO NCredit rating agencies (CRAs) have long been recognized as an important driver of financial and macroeconomic dynamics.1 Since the outbreak of the East Asian crisis, authors such as Ferri, Liu, and Stiglitz (1999) have pointed out their role in over-downgrading crisis-hit countries, and re-enforcing recessionary spirals. More recently, researchers such as Arezki, Candelon, andSy (2011) andDe Santis (2012) have provided evidence as to how European sovereign ratings have a significant impact upon interest rates, while Gande and Parsley (2004b) and Kim and Wu (2008) have provided evidence on the link between sovereign ratings and international capital flow movements. More critical authors have pointed out the role of CRAs as the 'gatekeepers' of the financial market and have highlighted the political dimensions of their power in prescribing the 'right' sets of policies (see for instance Kundu, 2001;Sinclair, 1993Sinclair, , 2005. Through their sovereign rating instruments, CRAs have facilitated the promotion of fiscal austerity and have actively encouraged market-friendly policies, such as privatizations, in 1 Despite the numerous registered agencies across the globe, it is three of them that dominate the market, namely Standard and Poor's (S&P), Moody's and Fitch. Nonetheless, the effects of sovereign ratings on economic outcomes have not been investigated to date in a macroeconomic model. This is done here by means of a two-country stock flow consistent (SFC) model. Originating from the seminal contributions of Godley and Lavoie (see Godley, 1999;Godley & Lavoie, 2007a, 2007b, SFC modeling has emerged as a lively stream of research in recent years. With the principle of double-entry bookkeeping at its core, SFC modeling offers a framework that allows the real and monetary sides of the economy to interact with each other in a genuine way. Money and credit are allowed to have real effects in both the short and the long run, and the financial sector is allowed to embody an institutionally specific content (for a recent article over the advantages of SFC modeling see Michell, 2016; for an up to date literature survey see Caverzasi & Godin, 2015).The aim of our model is to elucidate the links between movements in sovereign ratings, the financial market and the constraints that are placed on fiscal policy withi...
