Gas storage valuation under limited market liquidity: an application in Germany

Natural gas storages may be valued by applying real options theory. However, it is crucial to take into account that most evolving gas markets, like the German spot market, lack liquidity. This implies that large-scale operation of storages reduces the achievable operating margin since storage operators will pay higher prices for injected gas and earn less on withdrawn gas. Optimal storage operation will take this into account. In this context, considering storage operators as price takers does not account for interdependencies of storage operations and market prices. This paper offers a novel approach to storage valuation taking into account the effect of management decisions on market prices. The methodology proposed within this paper determines the optimal production schedule and value by determining the stochastic differential equation describing the storage value and then applying a finite difference scheme. We find that limited liquidity lowers the storage value and reduces withdrawal and injection amounts. Further, we observe decreasing reservation prices for injection and withdrawing for growing illiquidity resulting in a left shift of injection and withdrawing threshold prices.     

Location of Decision Rights in Catholic Religious Orders

Organizational incentives are an important part of applied economics. Do even organizations like religious orders make the same trade‐offs and substitutions as predicted by economics for firms? It is argued here that religious orders face the problem of controlling the actions of their branch offices to assure the continued value and uniqueness of their trademark. We use the distinction between specific and general knowledge to analyze the optimal colocation of decision rights within the specific knowledge framework of a religious order. Assuming that knowledge is valuable in decision making, then the colocation of the decision authority with the particular knowledge that is beneficial to those decisions is preferable. With a sample of 114 local communities of 20 religious orders of the Roman Catholic Church, we empirically test whether the ratio of search/experience goods, of credence goods and the monitoring costs of the headquarter can explain the colocation of decision rights and authority within an order. Our findings give support for the hypothesis that religious orders at present make the same trade‐offs and substitutions as predicted by economics. Copyright © 2012 John Wiley & Sons, Ltd.     

Planning or free market economy in LDCs?

On the face of it it looks as if there should be no great difference between less developed countries (LDCs) and the advanced national economies as far as planning is concerned. And yet in reality such differences do exist, even if they do not necessarily stem from the inequalities in the standard of living.

The Productivity Effects of Worker Mobility Between Heterogeneous Firms

We analyze the effect of worker inflows on establishments’ productivity, using German data. Previous studies for other countries have found positive effects of hiring workers from superior (more productive or higher paying) firms. Ranking establishments by their median wage, we find that inflows from inferior establishments seem to increase hiring establishments’ productivity. Further empirical analyses suggest our findings are due to a positive selection of such inflows from their sending establishments. These workers might have to find a better job match in order to advance their careers, an interpretation supported by the finding that the effect is driven by workers with short tenure at their previous employer. Our findings reflect the increasingly assortative pattern of worker mobility in Germany found in a related strand of literature.     

Unfolding implementation in industrial market segmentation

Market segmentation is an important method of strategic marketing and constitutes a cornerstone of the marketing literature. It has undergone extensive scientific inquiry during the past 50 years. Reporting on an extensive review of the market segmentation literature, the challenging task of implementing industrial market segmentation is discussed and unfolded in this article. Extant literature has identified segmentation implementation as a core challenge for marketers, but also one, which has received limited empirical attention. Future research opportunities are formulated in this article to pave the way towards closing this gap. The extent of implementation coverage is assessed and various notions of implementation are identified. Implementation as the task of converting segmentation plans into action (referred to as execution) is identified as a particularly beneficial focus area for marketing management. Three key elements and challenges connected to execution of market segmentation are identified — organization, motivation, and adaptation.     

An econometric analysis of demand for food quantity and quality in urban China

This article offers an analytical framework for studying consumer demand for food quality based on a theory‐consistent demand model, namely, the Exact Affine Stone Index specification. Importantly, it accounts for unobserved consumer and regional heterogeneity, and allows for arbitrary Engel curves. The empirical value of our framework is illustrated in an econometric analysis of demand for food quality in China. Evaluating possible structural changes in consumer food expenditures in China is of paramount importance, given the ever‐increasing global role of China and the implications of the structural food preference changes for the global food system. The major findings emerging from this study indicate that income is an important determinant of demand for food quality and quantity with the relatively more affluent provinces having a higher affinity for food quality.
