4 Robust empirical finding: Money wages do not fall during an economic downturn. Data from personnel files: Altonji & Devereux (2000), Baker, Gibbs & Holmstrom (1994), Fehr & Goette (2005), and Wilson (1999). Survey/register data in Altonji & Devereux (2000), Akerlof, Dickens & Perry (1996), Dickens et. al. (2007), Fehr & Goette (2005), Holden & Wulfsberg (2008) and others. Interviews or surveys with wage setters like Agell & Lundborg (2003), and Bewley (1999). 3 Mikael Carlsson and Andreas Westermark Optimal Inflation Rate

15 Purpose The purpose of this paper is to study the implications for monetary policy in terms of optimal average inflation when: There is a role for money as a medium of exchange. Declining nominal wages might not be a viable margin for adjustment. State dependent price/wage setting - Lucas critique. Deterministic aggregate productivity growth - important, since it pushes optimal inflation down substantially. Stochastic idiosyncratic productivity to match the empirical wage change distribution. 7 Mikael Carlsson and Andreas Westermark Optimal Inflation Rate

44 Bargaining When a firm/household pair renegotiates the wage, bargaining takes place in a setup similar to the model by Holden (1994). In the model, the parties bargain every period. Each bargaining round starts with one of the parties making a bid, then the other party responds yes or no. There are two key features of the Holden (1994) model. 18 Mikael Carlsson and Andreas Westermark Optimal Inflation Rate

48 First: If the response is no, there is a choice whether to continue bargaining in good faith and post a counter offer or enter into disagreement. If the latter choice is made, there is a probability that the match breaks down and the wage is determined in a standard Rubinstein-Ståhl fashion. Moreover, in case a party initiate bargaining under disagreement, both parties face their own known fixed disagreement cost (randomly drawn at the beginning of each period). This cost may be due to deteriorating firm/worker relationships. Similar to Holden (1994), but with probability of breakdown instead of strikes. 19 Mikael Carlsson and Andreas Westermark Optimal Inflation Rate

53 Second: There is an old contract in place at the firm and if there is no new wage agreement, workers work according to the old contract. As pointed out by Holden (1994), this is a common feature of many western European countries. As soon as there is bargaining under disagreement, payoffs are determined in a standard Rubinstein-Ståhl bargaining game and the disagreement costs is paid out of the parties respective pockets. A credible threat leads to immediate renegotiation and hence no disagreement in equilibrium. To derive only downward nominal rigidity, asymmetries in disagreement costs are required.
