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.  相似文献

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.  相似文献

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.  相似文献

In the last decades, financial activities have grown disproportionately compared to other activities. This aroused a growing discussion in Keynesian and Marxian economists about the structures of modern capitalism and the role played by the dominance of finance on capital accumulation. After a brief review of the main issues, we discuss some mechanisms explored in this literature connecting financialization and aggregate investment.  相似文献

The aim of this paper is to explore the environmental value of the Maker movement, which is driving digital fabrication into the mainstream. Makers are inspiring each other to create smart solutions for all types of individual needs and address societal and environmental challenges at the same time. They share their creative ideas and solutions in collaborative work spaces and Maker Faires or on social media platforms. Is this grassroots innovation the beginning of the next industrial revolution? This paper will explore the environmental value and impact of makers' innovative business model and discuss on how to increase the circularity. At the same time, we will describe the role of maker communities and how to help to play a better role. In the framework of a case study analysis based on 10 different Maker initiatives across Europe, 39 interviews were conducted with makers and Maker initiatives managers evaluating core questions such as potential environmental value and impact, value chains, and energy efficient behaviours. This study is expected to contribute to building an explorative but yet empirically rooted analysis of the environmental value and impact of the Maker movement. Furthermore, the challenges in the future and the suggestions for policy makers are provided.  相似文献

Metals are very important resources for industrial production, but recently they have attracted more and more attention from investors. While certainly industrial producers, consumers, and financial investors do have some influence on metal price development, the role of relevant price factors is not yet quite clear. Therefore, in this paper, we examine the explanatory power of various fundamental factors and characteristics known from financial markets, specifically on the expected returns in a unique data sample of 30 metals. We apply—to our knowledge for the first time in this context—the widely accepted method of characteristic-sorted portfolios, extended by the very recent method of two-way portfolio sorts as an alternative to classical multivariate regressions. This mostly nonparametric approach, combined with portfolio aggregation, provides very robust results. Our major finding is that the financial characteristics value and momentum have a very high predictive power for monthly returns of metal portfolios. Metal-specific fundamental factors like stocks, secondary production, apparent consumption, country concentration, mine production, or reserves perform depending on the interpretation moderately well or rather poorly, regarding some economically interpretable transformations and when using multivariate two-way sorts. Hence, from the perspective of expected returns, metals are predominantly assets, while fundamental metal-specific factors still play a non-negligible role. Thus, to a much lesser extent, metals can still be regarded as resources. Overall, the combination of financial characteristics and metal-specific fundamental factors yields the best results. With these robust results, we hope to contribute to a better understanding of metal prices and their underlying factors.  相似文献

Germany has one of the highest current account surpluses in the world. This is criticised by its global trading partners and is subject to the European Macroeconomic Imbalance Procedure. The authors interpret this phenomenon quite disparately. Some state that the surplus is not the result of continuously and structurally slower imports relative to export growth. Instead, two periods of weak domestic demand have left lasting traces. This should not result in programmes to stimulate the demand side. Others, however, find that Germany should identify ways to increase its domestic demand, especially its public and private investment, in order to reduce its surplus. It is hard to exactly quantify and target an appropriate level of the current account, and thus political action should focus directly on the distortions and misallocations that potentially result from an imbalance. By 2020, however, the German surplus is likely to decrease due to demographic developments, the housing boom and slowing globalisation. Since the rotation of fixed income assets out of Europe (“Euroglut”) is likely to continue, the outlook for the future value of the euro is therefore even more bearish.  相似文献

Improving the economic conditions for small and medium sized firms as well as start-ups is high on the agenda of policy makers. In this paper we discuss some policy options for fostering the creation of new enterprises. The discussion focuses on measures which aim at helping start-ups to overcome liquidity constraints. In order to provide the background for this discussion the paper provides some new empirical results on the determinants of firm foundations as well as some stylised facts on the occurence of liquidity constraints in West-Germany. We analyse the regional distribution of start-up intensity and offer several hypotheses to explain this distribution. To a large extent, the regional distribution of start-ups can be explained by the existing industry structure, regional human capital as well as the regional public traffic infrastructure. Moreover, we show that liquidity constraints occur more often in small and young firms.  相似文献
