Another view on optimal design for estimating the point of extremum in quadratic regression

In this paper we illustrate how certain design problems can be simplified by reparametrization of the response function. This alternative viewpoint provides further insights than the more traditional approaches, like minimax, Bayesian or sequential techniques. It will also improve a practitioner’s understanding of more general situations and their “classical” treatment.     

A note on the anti-herding instinct of interest rate forecasters

With regard to interest rate forecasts, earlier researchers have found mixed evidence of forecaster herding. Using the Livingston survey data, we reexamined the case for forecaster herding. We did not find evidence of forecaster herding. On the contrary, we found strong evidence of forecaster anti-herding.     

Information acquisition in conflicts

This paper considers incentives for information acquisition ahead of conflicts. First, we characterize the (unique) equilibrium of the all-pay auction between two players with one-sided asymmetric information where one player has private information about his valuation. Then, we use our results to study information acquisition prior to an all-pay auction. If the decision to acquire information is observable, but not the information received, one-sided asymmetric information can occur endogenously in equilibrium. Moreover, the cut-off values of the cost of information that determine equilibrium information acquisition are higher than those in the first best. Thus, information acquisition is excessive. In contrast, with open or covert information acquisition, the equilibrium cut-off values are as in the first best.     

Modelling country default risk as a latent variable: a multiple indicators multiple causes approach

We study the determinants of country default risk by applying a Multiple Indicators Multiple Causes (MIMIC) model. This accounts for the fact that country default risk is an unobservable variable. Whereas existing (regression-based) approaches typically use only one of several possible country default risk indicators as the dependent variable, the MIMIC model enables us to consider several indicators at once. The simultaneous consideration of sovereign yield spreads and Standard and Poor (S&P) ratings may help to improve the identification of the latent country default risk. Our results confirm most of the literature's main findings regarding important determinants of country default risk, refute others and provide new evidence to controversial questions.     

Oil price forecasting under asymmetric loss

Based on the approach developed by Elliott et al. (2005), we found that the loss function of a sample of oil price forecasters is asymmetric in the forecast error. Our findings indicate that the loss oil price forecasters incurred when their forecasts exceeded the price of oil tended to be larger than the loss they incurred when their forecast fell short of the price of oil. Accounting for the asymmetry of the loss function does not necessarily make forecasts look rational.     

A new approach to the identification of regional clusters: hierarchical clustering on principal components

This study focuses on the identification of regional business clusters as a primary step in the design and implementation of cluster-based development strategies. A methodology that has not been used previously to identify clusters is applied to data on inter-industry linkages from the input–output table of a region in northern Spain. The first advantage of this approach, hierarchical clustering on principal components (HCPC), over the use of factorial analysis alone, is that it involves the application of objective clustering techniques to the principal components analysis results, which leads to a better cluster solution. A second advantage is derived from using a mixed algorithm for the clustering process – a combination of the Ward’s classification method with the K-means algorithm – which improves the robustness of the final results.     

International parity relationships between Germany and the USA revisited: evidence from the post-DM period

In this study, we show the interrelation of the purchasing power parity and the uncovered interest rate parity between the US and Germany for the recent period running from 1999:01 to 2014:04. This study extends the literature by testing both hypotheses simultaneously in a multivariate ECM. This has the advantage that interactions between capital and goods markets can be considered simultaneously. Our finding of two long-run relationships between the variables shows that a disequilibrium in one of the two markets leads to a disequilibrium in the other. While analysing the reaction to cumulative shocks, we show that US variables have a greater impact on German variables than vice versa. Therefore, the rising importance of the euro and the increased integration of the European Union in the recent decade have not changed this relation.     

From economic stability to social order: The debate about business cycle theory in the 1920s and its relevance for the development of theories of social order by Lowe,Hayek and Eucken∗

Abstract

The concepts of Adolph Lowe, Friedrich A. Hayek and Walter Eucken play an important role in the discussion of an adequate theory of economic and social order. It is noteworthy that at the beginning of their academic careers, these three economists dealt primarily with questions of business cycle theory. As we will show, this is not coincidental, but can be explained by economic history and the history of theory. Furthermore, all three economists agree that establishing a comprehensive social order would provide the basis for economic stability, although each postulates a different relationship between liberty and order.     

The World Market for Labor and the World Market for Industrial Sites

At the center of the on-going debate about the U.S. Social Security system is the question of whether the way the system is financed can cope with the future challenges posed by the retiring Baby Boom generation. The "reformers" suggest changing the design of the system by moving to fully funded defined contribution retirement plans. Others argue that the so-called demographic problems are being used as an excuse to privatize the system. But both sides spend almost all of their energy and time figuring out the timing of insolvency of the system and the validity of the assumptions made in each forecast. In contrast, the present study closely examines the changing macroeconomic dynamics of the system since the 1960s. The analysis shows that undermining of the system is caused not by demographic changes or financing mechanisms but by low wages and medical inflation.
