Imputed Rent and Income Inequality: A Decomposition Analysis for Great Britain, West Germany and the U.S.

This article deals with income advantages derived from owner-occupied housing and their impact on the personal income distribution. Using micro-data from the British Household Panel Study (BHPS), the German Socio-Economic Panel (SOEP), and the U.S. Panel Study of Income Dynamics (PSID) we find distinct cross-national differences in terms of the prevalence and extent of imputed rent. Results from inequality decomposition analyses show this overall impact to be the net effect of two conflicting changes: On the one hand there is increasing income inequality between the groups of owneroccupiers and renters, respectively, and, on the other hand, we find inequality to be decreasing within the group of those owner-occupiers who own outright. When focussing on imputed rent as a means of old-age provision, our results for all three countries show an income advantage for, as well as a poverty reducing effect among the elderly. The empirical findings support the claim for the need of an improved harmonization of this non-cash income component especially for the purpose of cross-national comparative research.     

Smoothing the payoff for efficient computation of Basket option prices

We consider the problem of pricing basket options in a multivariate Black–Scholes or Variance-Gamma model. From a numerical point of view, pricing such options corresponds to moderate and high-dimensional numerical integration problems with non-smooth integrands. Due to this lack of regularity, higher order numerical integration techniques may not be directly available, requiring the use of methods like Monte Carlo specifically designed to work for non-regular problems. We propose to use the inherent smoothing property of the density of the underlying in the above models to mollify the payoff function by means of an exact conditional expectation. The resulting conditional expectation is unbiased and yields a smooth integrand, which is amenable to the efficient use of adaptive sparse-grid cubature. Numerical examples indicate that the high-order method may perform orders of magnitude faster than Monte Carlo or Quasi Monte Carlo methods in dimensions up to 35.     

Money Illusion and Housing Frenzies

A reduction in inflation can fuel run-ups in housing pricesif people suffer from money illusion. For example, investorswho decide whether to rent or buy a house by simply comparingmonthly rent and mortgage payments do not take into accountthe fact that inflation lowers future real mortgage costs. Wedecompose the price–rent ratio into a rational component—meantto capture the "proxy effect" and risk premia—and an impliedmispricing. We find that inflation and nominalinterest ratesexplain a large share of the time series variation of the mispricing,and that the tilt effect is very unlikely to rationalize thisfinding.     

The Bridging Role of Expatriates and Inpatriates in Knowledge Transfer in Multinational Corporations

Drawing on the knowledge‐based view of the firm, this article provides the first empirical study that explicitly investigates the relationship between different categories of international assignees and knowledge transfer in multinational corporations (MNCs). Specifically, we examine (1) the extent to which expatriate presence in different functional areas is related to knowledge transfer from and to headquarters in these functions and (2) the extent to which different categories of international assignees (expatriates vs. inpatriates) contribute to knowledge transfer from and to headquarters. We base our investigation on a large‐scale survey, encompassing data from more than 800 subsidiaries of MNCs in 13 countries. By disaggregating the role of knowledge transfer across management functions, directions of knowledge transfer, and type of international assignees, we find that (1) expatriate presence generally increases function‐specific knowledge transfer from and, to a lesser extent, to headquarters; and that (2) the relevance of expatriates and former inpatriates varies for knowledge flows between headquarters and subsidiaries. Additionally, we discuss implications for research and practice, in particular regarding different management functions and different forms of international assignments, and provide suggestions for future research. © 2015 Wiley Periodicals, Inc.     

A tale of two Ginis in the US, 1921–2012

Following a methodology by Jantzen and Volpert (2012), we use IRS Adjusted Gross Income data for the US (1921–2012) to estimate two Gini indices representing inequality at the bottom and the top of the income distribution, and to calculate the overall Gini as a function of the parameters underlying the two indices. A steady increase in the overall Gini since the Second World War actually hides two different periods of distributional changes. First, the increase in inequality from the mid 1940s to the late 1970s is driven by rising inequality at the bottom of the income distribution that more than offsets a decrease in inequality at the top. The implication is that middle-income earners gained relative to high-incomes, and especially relative to low-income earners. Second, the rise in the Gini after 1981 is driven by rising inequality at the top. Third, top-driven inequality follows a U-shaped trajectory consistent with Piketty and Saez (2003, 2006). Fourth, the welfare effects of the different distributional changes behind increasing inequality can be evaluated in light of the Lorenz-dominance criterion by Atkinson (1970): we argue that the rise in inequality since 1981 is much more likely to be associated with a social welfare loss net of compensating growth.     

Modeling FDI based on a spatially augmented gravity model: Evidence for Central and Eastern European Countries

Based on a spatially augmented gravity model, the current paper isolates spatial interrelationships in foreign direct investment (FDI) to Central and Eastern European Countries (CEECs) not only across the destination but also across the origin country dimension of FDI. Results show that (i) spatial interrelationships across destination countries are present and are consistent with the predominance of vertical-complex FDI in total FDI; (ii) spatial correlation across origin countries is given in earlier years of transition, while spillover and competition effects cancel over the whole sample period; and (iii) agglomeration forces gain in importance for FDI to CEECs.     

The relationship between job dissatisfaction and training transfer

The high rates of training transfer failure that prevail still puzzle practitioners as well as researchers. The central aim of the present study is to analyze the relatively under‐researched role of job dissatisfaction in the training transfer process. Specifically, we expect that job dissatisfaction would have a negative effect on transfer but that this effect would be buffered by the expectation of positive transfer consequences and motivation to transfer. To test these hypotheses, 220 participants in different training programs completed an online questionnaire 1 year after training. The results support our assumptions. They reveal that job dissatisfaction has a detrimental effect on training transfer, but that motivation to transfer and the expectation of positive transfer consequences have a buffering effect. The more motivated a person is towards transfer, the less negative is the effect of job dissatisfaction on actual transfer, but only if a person expects positive outcomes from transfer, such as acknowledgment or rewards. The findings are discussed in relation to existing training transfer models, as well as models of job (dis)satisfaction.     

Transdisciplinarity in Corporate Sustainability: Mapping the Field

Sustainability challenges are complex. So are the challenges that business firms encounter in their corresponding quest for corporate sustainability. Given this complexity, there is a need for new approaches to corporate sustainability management research. We discuss transdisciplinarity as such a novel approach in three steps. After showing that specialization is the primary conventional response to increasing complexity, we first briefly compare how inter‐, multi‐ and transdisciplinarity reintegrate decentralized, specialized knowledge. The second step describes how the emerging sustainability science has recently advanced the transdisciplinary methodology. Based on the two dimensions of interdisciplinarity and academia–practice collaboration, we third generate a framework for mapping existing research approaches in terms of their transdisciplinary qualities. We use this framework to identify room for novel methodologies in sustainability management research. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment.
