Nonstationarity of Real Exchange Rates in the G7 Countries: Are They Cointegrated with Real Variables?

Using monthly data for the G7 countries in the post-Bretton Woods floating rate period, this paper demonstrates that almost all bilateral real exchange rates have unit roots and, hence, are nonstationary. Consequently, it rejects simple PPP as a long-run relationship. The paper also shows that many of these real exchange rates are cointegrated with other real economic variables such as relative labor productivity, terms-of-trade ratios, real trade balance ratios, and long-term real interest rate differentials. In particular, relative labor productivity is statistically significant with the correct sign for more than half of the country pairs for which cointegration is confirmed. This finding lends support to the Balassa–Samuelson productivity-bias hypothesis. These results imply that nonstationarity of real exchange rates and the consequent rejection of simple PPP can be consistent with the notion that real exchange rates revert to an equilibrium in the long run without deviating arbitrarily far from this equilibrium position.J.

Expatriate utilization,subsidiary knowledge creation and performance: The moderating role of subsidiary strategic context

Little research examines the mechanisms for the relationship between expatriate utilization and subsidiary performance. Building on the knowledge-based view of the firm, we propose a multi-stage mediation model to explain how expatriate staffing promotes subsidiary financial performance. Our results underscore that expatriate utilization has an indirect, mediated effect on subsidiary financial performance through its links with subsidiaries’ knowledge creation and product performance. Adopting a moderated mediation approach, we also find that the indirect relationship between expatriate utilization and subsidiary product performance via subsidiary knowledge creation is strengthened by the context of transnational strategy as a moderating contingency.     

Nonperforming Loans and Purchase of Loans by Public Asset Management Companies in Malaysia and Thailand

This paper explores the factors which eliminated the nonperforming loan (NPL) problem in Malaysia and Thailand following the 1997 Asian financial crisis. The number of NPL, which expanded in the aftermath of the crisis, has since declined in most South‐East Asian countries. Although previous studies have explored the causes of the increase in NPL numbers, few have analysed the factors that contributed to the reduction in their number in Asia. In Malaysia and Thailand, authorities put in place several measures to manage NPL. As a vehicle to acquire NPL from banks, Malaysia established the Pengurusan Danaharta Nasional Berhad (Danaharta) in 1998, while Thailand established the Thai Asset Management Corporation (TAMC) in 2001. We analyse whether the characteristic features of banks, improvements in macroeconomic conditions, and facilities for purchasing loans caused a reduction in the number of NPL in Malaysia and Thailand. The results suggest that selling loans to a public asset management company was effective in reducing the number of NPL in Thailand. While macroeconomic conditions influenced the decline in NPL ratios in Thailand, in Malaysia, well performing commercial banks and large commercial and investment banks generally had smaller NPL ratios throughout and following the crisis.     

A multivariate Lévy process model with linear correlation

In this paper, we develop a multivariate risk-neutral Lévy process model and discuss its applicability in the context of the volatility smile of multiple assets. Our formulation is based upon a linear combination of independent univariate Lévy processes and can easily be calibrated to a set of one-dimensional marginal distributions and a given linear correlation matrix. We derive conditions for our formulation and the associated calibration procedure to be well-defined and provide some examples associated with particular Lévy processes permitting a closed-form characteristic function. Numerical results of the option premiums on three currencies are presented to illustrate the effectiveness of our formulation with different linear correlation structures.     

Perceived organizational support and expatriate performance: understanding a mediated model

What are the mechanisms by which multinational corporations (MNCs) can facilitate the effective performance of their expatriate staff in foreign countries? There is a substantial literature on expatriation, yet few studies have addressed how perceived organizational support (POS) may impact upon expatriates' work adjustment and affective commitment, and then on their job performance. We use data on 118 expatriates working at the German subsidiaries of Japanese MNCs, and demonstrate that career POS has a direct positive influence on work adjustment and affective commitment. Our results indicate that work adjustment fully mediated the relationship between career POS and task performance. We further discovered that both work adjustment and affective commitment play a pivotal role in mediating the impact of career POS on contextual performance. We discuss the practical implications of these findings and provide suggestions for future research.     

PERSONAL AND REGIONAL DETERMINANTS OF OUT‐MIGRATION FROM METROPOLITAN AREAS IN JAPAN

In this study, we focus on migration from metropolitan to outside areas in Japan, and quantitatively examine the personal and regional determinants of this process. At the regional level, our results show that the determinants of migration differ depending upon whether migration occurs from smaller to larger cities or vice versa. In the case of migration from larger to smaller cities, the residential environment beyond the metropolitan area is more important than employment opportunities. At the personal level, we analyzed the differences among the determinants of migration, looking at migrants according to age categories and based on their motivations for migrating. The main factors encouraging migration comprised opportunities for employment, education, and marriage.     

Robust pricing with refunds

Before purchase, a buyer of an experience good learns about the product's fit using various information sources, including some of which the seller may be unaware of. The buyer, however, can conclusively learn the fit only after purchasing and trying out the product. We show that the seller can use a simple mechanism to take best advantage of the buyer's post-purchase learning to maximize his guaranteed-profit. We show that this mechanism combines a generous refund, which performs well when the buyer is relatively informed, with non-refundable random discounts, which work well when the buyer is relatively uninformed.     

Optimal steady-state in stationary consumption-loan type models

We consider a stationary overlapping generations economy, and prove that an optimal steady state exists. We show that if a government intervention is needed in order to implement the optimal steady state as a competitive equilibrium, it is necessary only in a finite number of periods. If the interest rate associated with the optimal steady state equals the population rate of growth, some outside money may be required in order to make the competitive equilibrium follow the optimal steady state. We show that our existence result enables us to construct Pareto optimal competitive equilibria in some important cases.
