We explore the incentives for governments to cooperate by expanding expenditure. We model three countries, of which two are in a monetary union (the EU). The labour markets of both EU countries are unionized, and there is involuntary unemployment. We use a general model of bargaining, and explore in some detail the intra- and inter-country effects of changes in bargaining power. We then examine optimal government expenditure in each EU country. We find that there is a positive spillover, and that expenditures are strategic complements. The coordinated equilibrium involves higher expenditure than the uncoordinated equilibrium.
