Integrating neighbourhood effects in the calculation of optimal final tree diameters

Modern silvicultural treatments are based on single trees whereas classic forest economics look at the stand level. To accompany each other it is necessary to transfer the established economic models to the single tree level. This paper is an approach to use the Faustmann model and the corresponding marginal rate of return (Pressler percent) to derive value increment rates of single trees taking into account neighbourhood effects due to competition between individual trees. Furthermore, optimal rotation periods and optimal final diameters for future trees will be calculated.     

Does service intangibility affect entrepreneurial orientation?

Service firms face a unique set of challenges in their internationalization and foreign market growth. Their services' characteristics, particularly intangibility, constrain the options available to them for growth. When such firms are services International New Ventures (INVs), their challenges are combined with those related to rapid internationalization and growth. This research investigates how service intangibility and the typical challenges of INVs relate to the firms' Entrepreneurial Orientation and their foreign market growth. The findings show that indeed service intangibility has a relationship with firm proactiveness, risk-taking, and innovativeness; and that not all elements of Entrepreneurial Orientation have a positive impact on growth.     

Eine Bewertung verschiedener Kapazitätsmechanismen für den deutschen Strommarkt

This article examines the economic impacts of an implementation of different capacity mechanisms in the German market for electricity. We discuss selective mechanisms that address only newly installed capacity, as well as global mechanisms. Whenever appropriate, we give examples from international experience. We show that global mechanisms—contrary to selective mechanisms—can incentivize efficient investment decisions. However, due to the regulatory intensity of such mechanisms we advise not to take such measures unless a clear need is indicated.     

Work values of the next generation of business leaders in Shanghai, Tokyo, and Seoul

Understanding the work values of the current and future workforce is essential for designing a human resource management system that attracts, motivates, and retains talent. This study provides an updated, in-depth analysis of the work values of the next generation of business leaders in the commercial centers of China, Japan, and Korea. Although previous research has often clustered these countries together and labeled them Confucian Asia, survey results from more than 700 respondents reveal striking differences in work values across countries. The Chinese are more individualistic and career oriented, whereas the Japanese are more risk averse and work oriented, and the Koreans are often somewhere in-between. We argue that the value differences can be largely explained by different economic influences in these three countries. This study enhances our understanding of crossvergence theory by distinguishing economic influence in the economic development stage, economic growth, and inward foreign direct investments. While these economic indicators might be related, their influences on work values could be conflicting. The findings suggest that that each economic indicator has a unique effect on the development of work values.     

Induktives Laden von Elektromobilen – Eine techno-ökonomische Bewertung

Conductive (wired) charging, where the user has to plug or unplug a cable, dominates the concepts discussed for electric vehicles up to now. Apart from the reduced range of the electric vehicle, frequent charging and especially short charging times make this plugging and unplugging appear impractical. In contrast, inductive (wireless) energy transfer makes it possible to charge without user intervention. This article attempts to answer questions on whether inductive energy transfer can already be used to charge electric vehicles and where this represents an economically attractive solution for users. To do so, first the charging technologies are presented and contrasted. It is also possible to compare the two charging technologies economically based on a cost analysis. It can be shown that no widespread use of the inductive technology is to be expected for the time being from an economic point of view due to its significant extra costs. Under certain conditions, however, there is a limited field of application as a niche technology in certain commercial areas, such as taxis, for example.     

Accumulation points of the iterative proportional fitting procedure

The asymptotic behavior of the iterative proportional fitting procedure (IPF procedure) is analyzed comprehensively. Given a nonnegative matrix as well as row and column marginals the IPF procedure generates a sequence of matrices, called the IPF sequence, by alternately fitting rows and columns to match their respective marginals. We prove that the IPF sequence has at most two accumulation points. They originate as the limits of the even-step subsequence, and of the odd-step subsequence. The well-known IPF convergence criteria are then retrieved easily. Our proof is based on Csiszár’s and Tusnády’s (Stat Decis Suppl Issue 1:205–237, 1984) results on the interplay of the I-divergence geometry and alternating minimization procedures.     

Cosmopolitan career choices: a cross-cultural study of job candidates' expatriation willingness

Cosmopolitanism, i.e. openness to divergent cultural experiences, has become a desired characteristic of today's global managers. This study investigates the antecedents of cosmopolitanism and expatriation willingness as a final outcome. The results of surveys in Germany and South Korea demonstrate that cosmopolitanism is a strong predictor of job candidates' expatriation willingness. However, there are some differences in the antecedents of cosmopolitanism between the respondents from the two countries. Living and travelling abroad increase cosmopolitanism for Germans, whereas they have no effect on Koreans. For Germans, cosmopolitanism mediates the relationship between various international exposure variables and expatriation willingness. Explanations and practical implications are provided.     

STRATEGIC OBJECTIVES FOR STATE‐OWNED ENTERPRISES AS A MEANS TO MITIGATE POLITICAL INTERFERENCE: AN EMPIRICAL ANALYSIS OF TWO SWISS STATE‐OWNED ENTERPRISES

When governments act as owners of state‐owned enterprises (SOEs), they are both principal and agent at the same time. The literature on steering SOEs has mainly focused on the government as the principal that must control SOEs. However, the government is also an agent, vis‐à‐vis the parliament, because democratic constitutions stipulate some form of parliamentary oversight of the government. This oversight includes checks on how the government steers SOEs. However, this oversight function gives the parliament the power and opportunity to interfere into steering SOEs, which may lead to parliamentary interventions that are not coherent with governmental steering. We draw on principal–agent literature and public‐accountability literature to show that arbitrary and hands‐on parliamentary interference pose problems for steering SOEs. We analyze whether strategic objectives for SOEs, as recommended by public corporate governance guidelines, are appropriate to minimize parliamentary interference. We hypothesize that the Swiss government avoids or mitigates parliamentary interference by mid‐term strategic objectives for SOEs, which counteract short‐term parliamentary requests. We find that the Swiss government uses mid‐term strategic objectives, particularly financial ones, to reject parliamentary demands for more intervention into SOE activities.
