Swedish Freight Demand: Short, Medium, and Long Term Elasticities
- 2012
-
Ingår i: Journal of Transport Economics and Policy. - 0022-5258. ; 46, s. 79-97
-
Tidskriftsartikel (refereegranskat)abstract
- This paper explores empirical linkages between cycles and trends in freight transportation activity and real economic activity in Sweden. It decomposes freight demand into short-term, medium-term and long-term components and analyzes differences and similarities of the three time horizons. The finding is that freight demand is coupled with GDP over the long-term and that there are no signs of decoupling. Freight demand, furthermore, is highly volatile over the short to medium term and these fluctuations are largely an effect of temporary changes in imports and exports.

European trends in epilepsy surgery.

- Resective surgery is effective in treating drug-resistant focal epilepsy, but it remains unclear whether improved diagnostics influence postsurgical outcomes. Here, we compared practice and outcomes over 2 periods 15 years apart.Sixteen European centers retrospectively identified 2 cohorts of children and adults who underwent epilepsy surgery in the period of 1997 to 1998 (n = 562) or 2012 to 2013 (n = 736). Data collected included patient (sex, age) and disease (duration, localization and diagnosis) characteristics, type of surgery, histopathology, Engel postsurgical outcome, and complications, as well as imaging and electrophysiologic tests performed for each case. Postsurgical outcome predictors were included in a multivariate logistic regression to assess the strength of date of surgery as an independent predictor.Over time, the number of operated cases per center increased from a median of 31 to 50 per 2-year period (p = 0.02). Mean disease duration at surgery decreased by 5.2 years (p < 0.001). Overall seizure freedom (Engel class 1) increased from 66.7% to 70.9% (adjusted p = 0.04), despite an increase in complex surgeries (extratemporal and/or MRI negative). Surgeries performed during the later period were 1.34 times (adjusted odds ratio; 95% confidence interval 1.02-1.77) more likely to yield a favorable outcome (Engel class I) than earlier surgeries, and improvement was more marked in extratemporal and MRI-negative temporal epilepsy. The rate of persistent neurologic complications remained stable (4.6%-5.3%, p = 0.7).Improvements in European epilepsy surgery over time are modest but significant, including higher surgical volume, shorter disease duration, and improved postsurgical seizure outcomes. Early referral for evaluation is required to continue on this encouraging trend.

A comparison of linear forecasting models and neural networks: an application to Euro inflation and Euro Divisia

Tidskriftsartikel (refereegranskat)abstract
- Linear models reach their limitations in applications with nonlinearities in the data. In this paper new empirical evidence is provided on the relative Euro inflation forecasting performance of linear and non-linear models. The well established and widely used univariate ARIMA and multivariate VAR models are used as linear forecasting models whereas neural networks (NN) are used as non-linear forecasting models. It is endeavoured to keep the level of subjectivity in the NN building process to a minimum in an attempt to exploit the full potentials of the NN. It is also investigated whether the historically poor performance of the theoretically superior measure of the monetary services flow, Divisia, relative to the traditional Simple Sum measure could be attributed to a certain extent to the evaluation of these indices within a linear framework. Results obtained suggest that non-linear models provide better within-sample and out-of-sample forecasts and linear models are simply a subset of them. The Divisia index also outperforms the Simple Sum index when evaluated in a non-linear framework.

Admissible monetary aggregates for the euro area

Tidskriftsartikel (refereegranskat)abstract
- We use the Fleissig and Whitney [Fleissig, A.R., Whitney, G.A., 2003. A new PC-based test for Varian's weak separability conditions. Journal of Business and Economics Statistics 21 (1), 133-144] weak separability test to determine admissible levels of monetary aggregation for the Euro area. We find that the Euro area monetary assets in M2 and M3 are weakly separable and construct admissible Divisia monetary aggregates for these assets. We show that real growth of the admissible Divisia aggregates enters the Euro area IS curve positively and significantly for the period from 1980 to 2005. Out of sample, we show that Divisia M2 and M3 appear to contain useful information for forecasting Euro area inflation. (c) 2008 Elsevier Ltd. All rights reserved.

Inflation Forecasting, Relative Price Variability and Skewness

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We aim to forecast U.K. inflation out-of-sample. Our study uses disaggregated quarterly UK consumption data from 1964:1 to 2004:3. A major finding of our analysis is that inflation forecasts of long time horizons of 1.5-2 years are significantly improved if a measure of symmetry of the price distribution is incorporated into the forecast equation. In contrast, the inclusion of price variability leads to deterioration in inflation forecasting performance.

Predictable non-linearities in US inflation
- 2006
-
Ingår i: Economics Letters. - : Elsevier BV. - 0165-1765. ; 93:3, s. 323-328
-
Tidskriftsartikel (refereegranskat)abstract
- This paper compares the out-of-sample inflation forecasting performance of two non-linear models; a neural network and a Markov switching autoregressive (MS-AR) model. We find that predictable non-linearities in inflation are best accounted for by the MS-AR model.
