Building off the resource‐based view and the knowledge‐based view, our study aims to examine determinants of firms’ R&D outsourcing, using annually‐conducted firm‐level survey data of Japanese R&D companies from 1984–2012. This survey allows us to measure strategic R&D outsourcing, isolated from those more for cost‐reducing, such as prototyping, testing and inspecting. The results corroborate the argument of complementarity in scale between internal R&D and R&D outsourcing. We also find that firms employing more doctorate holders and diversifying in knowledge spaces tend to make more use of R&D outsourcing. This study sheds light on firms’ absorptive capacity, associated both with higher‐order R&D human capital and diversified knowledge spaces, as determinants of R&D outsourcing. 相似文献

This study proposes a new method for creating an index-tracking portfolio using time series decomposition. First, we construct index-tracking portfolios of stocks chosen because their price movements mimic that of the Dow-Jones Industrial Average. Our method utilizes similarities of constituent stocks to the benchmark that are assessed by distances of time series trends derived from decomposing original series. Although the portfolios chosen by our method reasonably tracked the performance of the benchmark, they did not surpass the clustering approach discussed in earlier studies. Therefore, we examined what causes tracking error and found that two causes for deficiencies in our similarity-based method, which are unintended irregular movements of holding stocks and highly correlated relationships within stocks in the portfolio. To overcome them and to improve tracking performance, we propose a similarity-balanced approach that is another index-tracking method with alternate use of similarity. Doing so improved the tracking performance by avoiding the problem of high correlation among the stocks chosen under the initial method. 相似文献

This paper assesses the effects of the most recent monetary policy behaviour of the Bank of Japan (in particular, zero interest rate policy and negative interest rate policy) and Japanese tax policy on income inequality in this country during the period of 2002Q1 to 2017Q3. The vector error correction model (VECM) that develops in this research shows that increase in money stock (m1) through Quantitative Easing (QE) and Quantitative and Qualitative Easing (QQE) policies of the BOJ significantly increases the income inequality. On the contrary, Japanese tax policy was effective in reducing the income inequality. Variance decomposition results show that increasing of income inequality by monetary policy is larger when comparing to decreasing effects of tax policy on income inequality. Cointegration and VECM results show that monetary policy has both short-run and long-run impacts but for tax policy paper could not find any significant short-run impact on income inequality. In addition, paper found that technological progress only in long-run can reduce the income inequality by increasing the marginal productivity of labour with positive impacts on employment and wages. 相似文献

We develop a general framework that extends choice models by including an explicit representation of the process and context of decision making. Process refers to the steps involved in decision making. Context refers to factors affecting the process, focusing in this paper on social networks. The extended choice framework includes more behavioral richness through the explicit representation of the planning process preceding an action and its dynamics and the effects of context (family, friends, and market) on the process leading to a choice, as well as the inclusion of new types of subjective data in choice models. We discuss the key issues involved in applying the extended framework, focusing on richer data requirements, theories, and models, and present three partial demonstrations of the proposed framework. Future research challenges include the development of more comprehensive empirical tests of the extended modeling framework. 相似文献

We use the 2008 short-selling ban to examine the impact of single-stock futures (SSFs) trading on options market quality. We show that there is a substitution effect between options trading and SSFs trading during the ban period. In addition, our results show that SSFs trading had a significant effect in narrowing the bid-ask spreads of options contracts. Moreover, compared to stocks without SSFs, stocks with SSFs were less likely to violate put-call parity during the ban period. Our results suggest that SSFs trading helps mitigate the negative effect of the short-selling ban on options market quality documented in the literature. 相似文献

The utilization of ASEAN free trade agreements (FTA) is low by international standards. To clarify the reasons for such low utilization, this paper uses unique affiliate‐level data to investigate what kinds of Japanese affiliates in ASEAN are more likely to use an FTA scheme in their exporting. Our findings are as follows. First, the larger the affiliate is, or the more diversified the origins of its procurements, the more likely it is to utilize an FTA scheme in its exporting. Second, affiliates that export actively to countries with higher general tariffs are more likely to use FTA. Third, there are clear differences in FTA utilization depending on affiliates' locations and sectors. 相似文献

Spatial Cournot competition and economic welfare: a note 总被引:1,自引:0,他引:1
We investigated welfare implications in location-quantity models in a symmetric linear city. We found that when firms are not agglomerated in equilibrium, increasing the distance between firms raises (reduces) producer surplus and social welfare (consumer surplus). Moreover, central agglomeration is always optimal for consumers among symmetric locations, but not necessarily for producers. Central agglomeration can be inefficient even if it is the unique equilibrium outcome. In short, the firms are more likely to agglomerate or locate closer than what welfare maximizers would dictate, whereas they locate farther apart than what consumer surplus maximizers would recommend. 相似文献

We revisit works by Pal and Matsushima, which, respectively, present different equilibrium locations. We consider nonlinear transport costs and show that Pal's result (dispersion) is more robust than Matsushima's (partial agglomeration). Pal's result holds true for any transport cost function, while Matsushima's does not hold under strong concavity or convexity of the transport cost function. If we consider sequential move of location. Pal's result holds for any transport costs. On the other hand, Matsushima's does not hold except for linear transport cost. We also discuss welfare and show that nonlinearity of the transport cost function yields rich welfare implications. 相似文献

The present paper investigates Zhou's (1999) money search model, where money is divisible, agents can hold any amount of money and production of goods is costly, and presents a sufficient condition, expressed in terms of exogenously given parameters, for the existence of single-price equilibria. 相似文献
