Multi‐Market Competition,R&D,and Welfare in Oligopoly

We investigate a multi‐market Cournot model with strategic process research and development (R&D) investments wherein a multi‐market firm meets new competitors that enter one of the markets. We show that entry can enhance the total R&D expenditures of the multi‐market firm. Moreover, the incumbent's profit nonmonotonically changes as the number of entrants increases. Depending on the fixed entry costs and R&D technologies, both insufficient and excess entry can appear. Our results imply that diversification of their products can be a useful strategy for firms.     

INTANGIBLE INVESTMENT IN JAPAN: MEASUREMENT AND CONTRIBUTION TO ECONOMIC GROWTH

Following the approach of Corrado, Hulten, and Sichel (2005, 2006 ), we measure intangible investment and examine the contribution of intangible capital to economic growth in Japan. We find that the ratio of intangible investment to GDP in Japan has risen during the past 20 years and now stands at 11.1 percent, which is lower than the ratio estimated for the U.S. in the early 2000s. The ratio of intangible to tangible investment in Japan is also lower than equivalent values estimated for the U.S. In addition, we find that, in stark contrast to the U.S., where intangible capital grew rapidly in the late 1990s, the growth rate of intangible capital in Japan declined from the late 1980s to the early 2000s. Our conclusions regarding intangible investment in Japan remain largely unchanged even if, using data with respect to firm-specific resources, we take on-the-job training into account.     

THE EFFECT OF KNOWLEDGE ACCESSIBILITY ON INTERNATIONAL INCOME INEQUALITY

Using a structural model of new economic geography, we estimate the effect of accessibility to foreign knowledge on international income distribution. Whereas previous literature has mainly focused on the importance of geographical accessibility to foreign markets, this paper emphasizes the role of accessibility to foreign knowledge in determining international income inequality. Using cross-country data of income per worker, bilateral trade flows, and number of flight passengers, we find evidence that the accessibility to foreign knowledge raises per capita income significantly.

Examining consumers’ sensory experiences with color: A consumer neuroscience approach

This research advances neuroscience as a tool with which to study consumers’ visual mental imagery. Applying these methods, we suggest that the presence or absence of color is a critical dimension along which consumers’ visualizations can vary, and explore when and why color of visual mental imagery becomes more prominent. Using functional magnetic resonance imaging (fMRI), we find neural evidence for distinguishing black-and-white (BW) versus color visualization, and that visual mental imagery becomes increasingly monochrome (vs. colorful) when consumers imagine distant (vs. near) future events. Our neural evidence further suggests construal level as the underlying mechanism of this effect, showing common regions of activation for imagining distant future events, engaging in high-level construal, and forming BW mental imagery. We discuss the implication of these findings and the benefits of fMRI techniques for marketing in general.     

PARTIAL PRIVATIZATION UNDER ASYMMETRIC MULTI‐MARKET COMPETITION

Under the assumption that a public firm provides goods or services to two markets and that a private firm provides goods or services to one market only, this study examines whether public firms should be privatized. It also investigates how the production quantity of a private firm changes when its degree of privatization increases. We find that when the market share of a duopoly market is large (small), partial privatization (nationalization) is socially preferable. We also find that the quantity produced by the private firm does not always increase along with the degree of privatization.     

Regime switches in exchange rate volatility and uncovered interest parity

We use a regime-switching model to examine how exchange rate volatility is related to the failure of uncovered interest parity. Main findings are as follows. First, exchange rate returns are strongly influenced by regime switches in the relationship between the returns and interest rate differentials. Second, low-yielding currencies appreciate less frequently, but once it occurs, their movements are faster than when they depreciate. Third, depreciation of low-yielding currencies and low volatility are mutually dependent on each other. Finally, these three findings are more evident for shorter horizons. The second and third results are consistent with a market participants’ view: short-term carry trades in a low-volatility environment and their rapid unwinding substantially influence exchange rates. We consider the effects of funding liquidity to explain these results.     

What Should the Weights of the Three Major Currencies be in a Common Currency Basket in East Asia?*

We consider what type of regional common currency should be introduced in East Asia in the future. The common currency basket is, in itself, more desirable as an anchor currency. In this paper we define two types of currency basket and investigate the long‐term sustainability of adopting a common currency basket in East Asia. From our empirical results, a larger weight (but less than 100 percent) for the US dollar in the common currency basket tends to make bilateral exchange rates among East Asian countries stable in the long run.     

A consistent nonparametric test for nonlinear causality—Specification in time series regression

Since the pioneering work by Granger (1969), many authors have proposed tests of causality between economic time series. Most of them are concerned only with “linear causality in mean”, or if a series linearly affects the (conditional) mean of the other series. It is no doubt of primary interest, but dependence between series may be nonlinear, and/or not only through the conditional mean. Indeed conditional heteroskedastic models are widely studied recently. The purpose of this paper is to propose a nonparametric test for possibly nonlinear causality. Taking into account that dependence in higher order moments are becoming an important issue especially in financial time series, we also consider a test for causality up to the Kth conditional moment. Statistically, we can also view this test as a nonparametric omitted variable test in time series regression. A desirable property of the test is that it has nontrivial power against T^1/2-local alternatives, where T is the sample size. Also, we can form a test statistic accordingly if we have some knowledge on the alternative hypothesis. Furthermore, we show that the test statistic includes most of the omitted variable test statistics as special cases asymptotically. The null asymptotic distribution is not normal, but we can easily calculate the critical regions by simulation. Monte Carlo experiments show that the proposed test has good size and power properties.
