  An important application in the real options literature has been to investments in the oil sector. Two commonly applied "stylized facts" in such applications are tested here. One is that the correlation of the returns on oil and the stock market is positive, the other that it is invariant to changes in oil price volatility. Both are rejected in data for 1993-2008 for crude oil and the S&P 500 stock market index. Based on real options theory, consequences are pointed out. A widespread idea, that higher volatility leads to increased value and postponed investment, is not necessarily valid.

  This paper investigates potential invariance of mean forecast errors to structural breaks in the data generating process. From the general forecasting literature, such robustness is expected to be a rare occurrence. With the aid of a stylized macro model we are able to identify some economically relevant cases of robustness and to interpret them economically. We give an interpretation in terms of co-breaking. The analytical results resound well with the forecasting record of a medium-scale econometric model of the Norwegian economy.

  This paper evaluates inflation forecasts made by Norges Bank which is a successful forecast targeting central bank. It is expected that Norges Bank produces inflation forecasts that are on average better than other forecasts, both ’naive’ forecasts, and forecasts from econometric models outside the central bank. We find that the superiority of the bank’s forecast cannot be asserted, when compared with genuine ex-ante real time forecasts from an independent econometric model. The 1-step Monetary Policy Report forecasts are preferable to the 1-step forecasts from the outside model, but for the policy relevant horizons (e.g., 4 quarters ahead), the forecasts from the outsider model are preferred with a wider margin. An explanation in terms of too high speed of adjustment to the inflation target is supported by the evidence. Norges Bank’s forecasts are better than the ‘naive’ forecasts. Norwegian inflation appears to be predictable, despite the reduction in inflation persistence that has taken place over the last two decades.

  Norway experienced a high immigration flow after the EEA directive in 2004 stating workers right to free movement within the European Union and EEA-countries. There is no clear consensus in the literature on how immigration affects native wages, but some studies using Norwegian micro data have estimated a negative effect of higher immigration for some type of workers. In this paper, to capture that the wage setting is highly coordinated in Norway, we model a system of native wages for three sectors; manufacturing, private service industries and public sector. We estimate that labour immigration has had a negative effect on the attainable wage growth for natives in all three sectors, but that the largest and most direct impact on wages has been in the private service industries. Immigration is found to be exogenous with respect to the parameters of our model of wage formation

  The new-Keynesian Phillips curve (NKPC) includes expected future inflation as a major feedforward variable to explain current inflation. Models of this type are regularly estimated by replacing the expected value by the actual future outcome, then using Instrumental Variables or Generalized Method of Moments methods to estimate the parameters. However, the underlying theory does not allow for various forms of non-stationarity in the data–despite the fact that crises, breaks and regimes shifts are relatively common. We investigate the consequences for NKPC estimation of breaks in data processes using the new technique of impulse-indicator saturation, and apply the resulting methods to salient published studies to check their viability.

• Nymoen, Ragnar & Kolsrud, Dag Olaf (2010). Macroeconomic Stability or Cycles? The Role of the Wage-price Spiral. Show summary

  We derive aggregate supply (AS) relationships for an intermediate-run macro model. The wage-price spiral provides the conceptual framework for a synthesis of different contesting theoretical and empirical perspectives on the AS curve: the Phillips curve model (PCM) and the wage-price equilibrium correction model (WPECM). The generalized AS curve is grafted into a small macro model. We analyze stability conditions, steady states, and dynamic solutions, using a combination of algebra and simulations. The specification of the AS curve, as a PCM or a WPECM, is shown to be important for all aspects of the model’s solution, but within each model also the detailed parameterization is of qualitative importance. For example, endogenous cyclical fluctuations are typical for both nominal and real variables, e.g. inflation and unemployment.
