On measuring speculative and hedging activities in futures markets from volume and open interest data

2010

This paper provides a critical assessment of the line of research that measures speculative and hedging activities in futures markets from volume and open interest data. It makes several contributions. First, a detailed theoretical analysis of the measures proposed in the previous literature as proxies for speculative activity clarifies the circumstances in which they fail, as well as the assumptions that have to be made, when they are used as intended. Second, we propose a new way of combining the volume and the open interest figures, which provides additional information regarding the type of trading activity that takes place in the market on a given date. Finally, we analyse empirically …

Work-life balance during the COVID-19 outbreak: the case of Latvia

2020

This paper aims to shed light on work-life balance in Latvia during the state of emergency The COVID-19 outbreak has led many governments to introduce lockdowns While imposed restrictions may help to contain the spread of the virus, they may also result in substantial damage to population well-being The COVID-19 outbreak in Latvia demonstrates the extent and ways in which socio-demographics factors have determined different patterns of behaviour, attitudes, employment changes and harmonised work and life balance The study describes the chronological development of COVID-19 in the country It describes labour migration to and from Latvia before the COVID-19 outbreak It provides geographical f…

Forecasting container transshipment in Germany

2009

International audience; In this paper, we examine container transshipment at German ports using the seasonal ARIMA (SARIMA) model and the Holt-Winters exponential smoothing approach. Our models are designed especially to take account of the seasonal behavior of the quarterly data used. We consider the dynamic development in this sector for the whole container throughput and also the destinations Asia, Europe and North America, which are the world's three main economic regions. Our data runs from the first quarter of 1989 to the fourth quarter of 2006. We provide detailed quarterly forecasts for the year 2007 and 2008. According to forecasting error measures such as Mean Square Error and The…

PRICE CONVERGENCE IN THE EUROPEAN CAR MARKET

2008

International audience; This paper examines price convergence in the European Union car market over the period 1995-2005. We find that there is a clear evidence of price convergence among the EU15 countries, but not before 1999. Moreover, countries of the Economic and Monetary Union (EMU) started convergence previously to the EU15 as a whole. Finally, exchange rate changes have significantly contributed to price dispersion over time across countries. The results provide significant evidence that trade liberalization and the EMU have enhanced the process of regional integration in the European automobile industry, even though there is room for further measures to promote integration.

Performance analysis of the closed loop supply chain

2012

Purpose The question of resource scarcity and emerging pressure of environmental legislations has brought a new challenge for the manufacturing industry. On the one hand, there is a huge population that demands a large quantity of commodities; on the other hand, these demands have to be met by minimum resources and pollution. Resource conservative manufacturing (ResCoM) is a proposed holistic concept to manage these challenges. The successful implementation of this concept requires cross functional collaboration among relevant fields, and among them, closed loop supply chain is an essential domain. The paper aims to highlight some misconceptions concerning the closed loop supply chain, to d…

Epistemic network analyses of economics students' graph understanding. An eye-tracking study

2020

Learning to solve graph tasks is one of the key prerequisites of acquiring domain-specific knowledge in most study domains. Analyses of graph understanding often use eye-tracking and focus on analyzing how much time students spend gazing at particular areas of a graph&mdash

A methodology to compare and adapt e-learning in the global context

2010

In this paper, we present a solution how to test cultural influences on E-Learning in a global context. Based on a metadata approach, we show how specifically cultural influence factors can be determined to transfer and adapt learning environments. We present a method how those influence factors can be validated for both, to improve the dynamical meta-data specification and to be used in the development of (international) E-Learning scenarios.
