We show how to construct optimal policy projections in Ramses, the Riksbank’s open‐economy medium‐sized dynamic stochastic general equilibrium model for forecasting and policy analysis. Bayesian estimation of the parameters of the model indicates that they are relatively invariant to alternative policy assumptions and supports our view that the model parameters may be regarded as unaffected by the monetary policy specification. We discuss how monetary policy, and in particular the choice of output gap measure, affects the transmission of shocks. Finally, we use the model to assess the recent Great Recession in the world economy and how its impact on the economic development in Sweden depends on the conduct of monetary policy. This provides an illustration on how Rames incoporates large international spillover effects. 相似文献

Long‐term contracting implies contracting based on expected future demand. In this paper, I develop a multiperiod procurement model where, once the actual level of demand is realized, the irreversible initial provision level may be supplemented by additional provisions. This paper shows that, with the possibility of additional upward adjustments, the first‐period provision level will be lower than when no additional adjustments are possible. This reduction in first‐period provision level is higher under complete contracting than under incomplete contracting, and because of the reduction in information rents it yields a higher expected utility to the principal but lower total welfare. 相似文献
