Administrative and Survey Data in Personnel Economics

The number of empirical studies in personnel economics using administrative data has grown rapidly in recent years. We survey the use of administrative data to examine employment contracts. Specifically, we consider three types of data that have been widely used in empirical studies: historical firm‐level records, contemporary firm‐level records and national matched employer–employee records. Studies using this sort of administrative data have shed considerable light on the nature of employment relationships.     

Real-time effects of central bank intervention in the euro market

This paper investigates the real-time effects of sterilized foreign exchange intervention using official intraday intervention data provided by the Danish central bank. Our analysis employs a two-step weighted least squares estimation procedure. We control for macro surprises, address the issue of endogeneity, and carry out an array of robustness tests. Only when the direction of intervention is consistent with the monetary policy stance do we find that intervention exerts a significant influence on exchange rate returns.     

Are momentum crashes pervasive regardless of strategy? Evidence from the foreign exchange market

This article studies the option-like behaviour of popular momentum strategies implemented in foreign exchange markets. The results confirm recent research findings of strong option-like behaviour for momenutm measures, based on the cumulative return from 12 and 6 months prior to the formation date Surprisingly, there is no such evidence for the popular momentum strategy accounting for a 1-month formation period.     

A mixed C-vine copula model for hedging price and volumetric risk in wind power trading

When energy trading companies enter into long-term agreements with wind power producers, where a fixed price is paid for the fluctuating production, they are facing a joint price and volumetric risk. Since the pay-off of such agreements is non-linear, a hedging portfolio would ideally consist of not only forwards, but also a basket of e.g. call and put options. Illiquidity and an almost non-existent market for options challenge however the optimal hedging of joint price and volumetric risk in many market places. Here, we consider the case of the Danish power market, and exploit its strong positive correlation with the much more liquid German market to construct a proxy hedge. We propose a three-dimensional mixed vine copula to model the evolution of the Danish and German spot electricity prices and the Danish wind power production. We construct a realistic hedging portfolio by identifying various instruments available in the market, such as real options in the form of the right to transfer electricity across the border and the right to convert electricity to heat. Using the proposed vine copula to determine optimal hedging decisions, we show that significant benefits are to be drawn by extending the hedging portfolio with the proposed instruments.     

Applying Strategic Management Theories in Public Sector Organizations: Developing a typology

This article discusses the utility of two different strategic management theories in different types of public organizations including contemporary New Public Management-based public organizations, namely Porter’s strategic positioning model and the resource-based view of strategy. We argue that possibilities for applying these theories vary depending on the type of public organizations involved, and are less appropriate in traditional settings but more relevant in autonomized and market-like service-delivery organizations. We further propose that their increased applicability depends on three specific conditions: the degree of administrative autonomy, performance-based budgeting and market-like competition. We give empirical examples drawn from public services in the UK and Denmark. We call for more exploration of these (and other) strategic management approaches within contemporary public services organisations but also more exploration of the limitations of these frameworks.     

Partnership in education: central service prepares students for materiel management duties

Partnership in education looks at one technical college's approach to meeting the demand for trained workers in central service and materiel management. This article examines the partnership formed between a college, area health care facilities, and industry to design, develop, and implement a central service materiel management program.     

Value relevance of voluntary disclosure in the annual report

This paper examines whether the level of voluntary disclosure affects the association between current returns and future earnings. Economic theory suggests that firms might find it advantageous to provide additional pieces of information (i.e. voluntary disclosure) to investors and analysts. Our results indicate that more voluntary disclosure does not improve the association between current returns and future earnings (i.e. current returns do not reflect more future earnings news). This finding raises the question of whether voluntary information in the annual report contains value‐relevant information about future earnings or if investors are simply not capable of incorporating voluntary information in the firm value estimates.     

With or Without U? The Appropriate Test for a U‐Shaped Relationship*

Nonlinear relationships are common in economic theory, and such relationships are also frequently tested empirically. We argue that the usual test of nonlinear relationships is flawed and derive the appropriate test for a U‐shaped relationship. Our test gives the exact necessary and sufficient conditions for the test of a U shape in finite samples in a large class of models.     

Effects of Household Consumption Patterns on CO2 Requirements

In order to evaluate the relation between the consumption pattern of various household types and their CO₂ requirements, we combine input-output tables energy flow matrices, CO₂ emissions factors, and national consumer survey statistics into an integrated modelling framework, and relate differences in household types to differences in private consumption and again to differences in CO₂ emissions. We identify household characteristics with a significant influence on CO₂ emissions. Comparing our results with those of other studies reveals that national differences in climate and population density cause differences in the contribution to CO₂ emissions. Finally, national differences in income and expenditure elasticities of both energy and CO₂ are due to differences in the disparity in CO₂ intensities amongst commodities and to the model's assumptions on foreign technology.
