Asymmetric correlations in gold and other financial markets

In this article, we implement a recently developed statistical method to test asymmetries in cross-asset correlations, focusing in particular on the gold market. Our empirical results provide evidence that gold exhibits asymmetric correlations with stocks and the U.S. dollar, but not with bonds. Furthermore, splitting the sample into three characteristic periods, we find that exceedance correlations exhibit substantial time variation even in similar market tensions for same pairs of assets. Our findings imply that investors and fund managers should take into account the asymmetric dependence structure, which depends on the upside or downside of the market.     

Interlinkages between systems, key components and component generic technologies in building competencies

In the paper, an analysis is made of the intolinkages between systems, key components and components' generic technologies in building technological competencies. The sample consists of a set of seven Japanese and four European firm in the industrial, consumer electronics and materials sectors, engaged in the field of optoelectronics. Three tyes of information-—scientific publications, US patenting and interview data—are used. The findings demonstrate the existence ofsuch interlinkages.It was possible to confirm empirically the concept of generic technologies which are the basic underbing technologies forming thefoundation of a range of key components. The generic technologia are important for all firms, irrespectives of their final product markets. Building capabilities at the upstream and over a long period allows firms to develop more high value-added systems and products. It also provides forms with the opportunity to branch into new areas.     

Measurement of redistributive effect of tax rates from a longitudinal perspective: an application of the fixed taxable income approach

The primary objective of this article is to explore how the redistributive effects of tax rate change when using the fixed taxable income approach – where tax rates for each year in a period are applied to taxable income for a base year to calculate rate effects – instead of using an existing procedure to compute the rate effects. Standard rate effects are found to differ considerably from those calculated using the fixed taxable income approach in terms of both level and longitudinal trend.     

Efficiency and Lack of Commitment in an Overlapping Generations Model with Endowment Shocks

This paper considers a pure exchange stochastic overlapping generations model in which, on each date, an economy faces an aggregate endowment shock. On each date, a young agent and an old agent simultaneously decide how much of their respective endowments to transfer to the other agent; however, a young agent cannot make promises about how much he or she will give when old. In this sense, an economy faces a limited commitment constraint. This paper characterizes an efficient intergenerational risk sharing allocation that satisfies a limited commitment constraint, and also studies the role of money and history in a stochastic overlapping generations economy.     

Protecting children's privacy online: How parental mediation strategies affect website safeguard effectiveness

Concern toward children's safety in an online environment has resulted in demands for safeguards to protect their online privacy when involved with a wide variety of commercial websites. Unfortunately, little academic research has examined how effective safeguards are in limiting children's disclosure of information. We fill this void by examining how proposed safeguards may interact with various types of parental involvement in limiting children's willingness to disclose information online. The results of two studies involving preteen, young teen, and older teen children show that safeguard effectiveness depends on both the type of parental mediation and the particular age group. Implications are presented for retailers, educators, and parents.     

Fiscal stimulus effectiveness in Japan: evidence from recent policies

This article examines the effects of Japanese fiscal policy after the 2008 global financial crisis using a mixed vector autoregression/event study approach. We focus on the effects of stimulus packages with environmental benefits. The empirical results show that a tax break and subsidy programme designed to promote the adoption of eco-friendly cars helped stimulate automobile production, while a similar programme intended to promote the purchase of energy-efficient appliances had no effect on appliance production.     

Management and Policy Concerns over Shifts in Innovation Trajectories: The Case of the Japanese Robotics Industry

Innovation related network systems would need to be re-aligned and adapted within major technological shifts and their capability to re-align themselves determines the dynamic capabilities of a national innovation system. In this paper, we present a particular phenomenon in industrial evolution, which we call a shift in the 'innovation trajectory', taking the case of the Japanese robotics industry that now undergoes major shifts in many respects. We consider activities directly involved with innovation in the entire value chain from invention to commercialization, and identify the structural changes in the national systems due to the shifts in innovation trajectory. Having utilized the basic framework of 'Techno Economic Network', this paper analyzes six different structural shifts, which are related to product, technology, market, actor, competitive and socio-economic structures. This paper draws attention to the fundamental management and policy level concerns over the emerging shifts at four different decision making hierarchical levels. With concrete empirical evidences and results from interviews, this paper concludes that a new set of approaches is needed to shape these emerging innovation shifts.     

The effects of fiscal policy in the 1990s in Japan: A VAR analysis with event studies

This paper examines the effects of Japanese fiscal policy during the 1990s. A mixed vector autoregression (VAR)/event study approach is used for this purpose. The first empirical finding is that in the late 1990s, the negative effect of fiscal policy was larger and more persistent than the positive effect. This finding suggests that the large fiscal expansions in the late 1990s were inadequate for stimulating the macroeconomy in terms of the size and persistence of their policy effects. The second finding is that the permanent tax cuts implemented in the former part of the 1990s increased consumer durable spending significantly and persistently. This increase may reflect consumers’ incentive to spend before the increase in the consumption tax rate in April 1997.
