This study extends the previous research into the effects of knowledge spillovers on innovation and regional exports growth by more clearly distinguishing, both theoretically and empirically, two different types of knowledge spillovers, namely product and market knowledge spillovers. More importantly, this research provides insights on their role of knowledge spillovers in shaping regional innovative activities and, eventually, regional export growths. Furthermore, this research makes an important contribution to the understudied market knowledge spillovers by developing two variables that could be used to assess the flow of market knowledge spillovers at the regional level: localization economies and export consulting advice. Using secondary data on eight 2-digit manufacturing industries in ten New Zealand regions over a seven year period, this research found that regional competition, localization economies and the availability of export consulting advice have positively and significantly impact on the regional export growth in New Zealand.

Purpose - This paper analyzes how Research and Development (R&D) cartelization and Research Joint Ventures (RJV) affect firms that engage in Cournot competition in their product market using a model in which the Home and Foreign firm produce differentiated products and export their total output to a third country's market. Design/Methodology - In a two-stage game, research expenditures incurred in the first stage improve product quality and are subject to various degrees of spillovers. We consider four different scenarios. Findings - In a symmetric equilibrium we observe the following: (i) an RJV that cooperates in R&D decision yields the highest R&D expenditure. However, the scenario which yields the lowest expenditure depends on the extent of differentiation between the goods and the degree of spillovers; (ii) RJV cartelization yields the highest product quality, output, and consumer surplus in the third country; however, the lowest is produced by R&D competition if spillovers are strong and by R&D cartelization if spillovers are weak; and (iii) each firm's profit is at its minimum in R&D competition and its maximum in RJV cartelization. Furthermore, if spillovers are strong, the profit of each firm in R&D cartelization is greater than that in RJV competition, and vice versa. Originality/value - By analyzing product innovation in international markets, we can find similarities and differences between process R&D and product R&D in international markets.

This paper analyzes the role of absorptive capacity in R&D spillovers through strategic R&D investments in a game-theoretic framework. In the model, a firm's effective R&D is composed of idiosyncratic R&D, which produces its own innovations, and identical R&D, which improves absorptive capacity. The model shows that in the presence of absorptive capacity firms have a tendency to underinvest (overinvest) in idiosyncratic (identical) R&D relative to the social optimum. As the spillover becomes larger, firms decrease their own R&D while they become more inclined towards strategic exploitation of rivals' efforts. Since the former effect overpowers the latter, the total amount of R&D decreases as the spillover increases. This is socially undesirable, providing a potential justification for a governmental subsidy for idiosyncratic R&D and a tax on identical R&D. The findings may have important implications for newly industrialized or emerging countries that consider a redirection of national R&D policy and intellectual property rights (IPR) regime.

본 연구에서는 두 나라의 대표적인 두 기업이 R&D 경쟁과 쿠르노 경쟁을 하는 상황을 전제로 외국기업의 R&D 외부효과가 국내 주요 경제변수에 어떤 영향을 미치며 나아가 국내정부의 보호수준과 어떤 관계를 갖는지에 대한 무역정책의 문제를 규명한다. 국제적 과점의 2단계 모형을 통해 우리는 자유무역과 보호무역 정책에서 존재하는 유일한 해를 구하고, 나아가 시뮬레이션 분석을 통해 R&D 투자의 외부효과에 따른 주요 경제변수들의 변화 패턴과 일국의 최적관세 패턴을 추적한다. 이론적인 주요 예측으로 기업들이 R&D 경쟁을 하고 있는 상황에서 자유무역과 보호무역 두 경우에 모두 R&D 외부효과가 클수록 R&D 투자율과 수준이 감소하고, 사회후생은 유사한 패턴을 보이지만 그 수준은 보호무역에서 상대적으로 큰 것으로 드러난다. 또 이 연구의 가장 관심사항인 R&D 투자의 외부효과와 최적관세율 간의 관계에서는 두 변수 간에 부(-)의 관계가 나타난다. 이는 정책적으로 R&D 투자의 외부효과가 커짐에 따라 최적관세율을 낮출 필요가 있음을 시사한다.

This paper contributes to the ongoing controversy over price and volatility spillovers across countries by providing new evidence with the futures data of the S&P 500 and Nikkei 225 index futures contacts from January 3, 1990 to April 16, 1996. Based on the two-stage symmetric and asymmetric GARCH models we document that both the U.S. and the Japanese daytime returns significantly influence the subsequent overnight returns of the other market. We find no signs of volatility spillovers between two international markets with the symmetric model. However, with the asymmetric models, we find that the magnitude of foreign negative shocks are different from the positive ones. The findings generally suggest that the two markets are more sensitive to the bad news originating in the other market. This nature of transmission between two markets would have important implications to the arbitragers who are trying to exploit the short-term dynamics of price and volatility movements across two security markets.

Using the indicators of economic policy uncertainty developed by Baker et al. (2016), this paper investigates the effects of the US economic policy uncertainty on the Korea economic uncertainty as well as Korea-US foreign exchange risk. The key findings are that: (i) the degree of spillovers of policy uncertainty from the US to Korea is considerable but not comparatively high; (ii) the US policy uncertainty plays a stronger and more consistent role in Korean currency risk than Korea policy uncertainty and other macro variables. It implies that the economic policy uncertainty in the US is an important contributor to Korea-US exchange rates.

This paper provides a theoretical setup for an analysis of strategic relationships inherent to activities of an innovative multinational enterprise (MNE) and a local company in a host country. Additionally, we explore the incentives of the host country's government to provide subsidies to attract foreign direct investment (FDI) and to protect outcomes of R&D activities conducted by the MNE. We show that the MNE's commercial interests may collide with local companies' over protection of IPRs. Therefore, the extent of knowledge spillovers from the MNE to the local company and the magnitude of incentives to the MNE perform a crucial function in determining the optimal policy mix of IPR protection and FDI subsidies of the host country's government.

본 논문에서는 각국 화폐의 환율변동성이 우리나라 원화의 환율변동성에 미치는 전이효과를 분석하였다. 분석을 위하여 G7 국가로서의 선진국 화폐인 일본 엔화, 유로화, 영국 파운드화, 캐나다 달러화와 우리나라가 지리적으로 가까이 위치해 있는 아시아 오세아니아 지역의 화폐인 태국 바트화, 인도네시아 루피아화, 싱가포르 달러화, 호주 달러화가 사용되었다. 연구기간은 2009년 1월부터 2017년 12월까지이며 주별 자료를 사용하였고 분석방법으로는 GARCH(1,1) 모형이 사용되었다. 분석결과, 일본 엔화, 유로화, 영국 파운드화, 태국 바트화 및 인도네시아 루피아화의 환율변동성이 우리나라 원화 환율변동성에 미치는 영향은 유의하지 않았으며, 캐나다 달러화, 싱가포르 달러화와 호주 달러화의 환율변동성이 우리나라 원화환율변동성에 영향을 미치는 전이효과는 유의하였다. 본 연구를 위하여 선택된 국가들을 경제체제와 구조면에서 평가해 볼 때, 일본, 영국 및 유로화 사용 국가는 우리나라보다 높은 수준에 있고, 태국과 인도네시아는 우리나라보다 낮은 수준에 있으며, 캐나다, 싱가포르, 호주는 비슷한 수준에 있다고 말할 수 있다. 그러므로 본 논문의 연구에서 우리나라 화폐의 환율변동성에 영향을 미치는 화폐로서 캐나다달러화, 싱가포르 달러화, 호주 달러화가 채택된 분석결과는 경제체제나 구조가 유사한 국가들 간의 환율변동성 전이현상 때문에 나타난 결과라고 추정할 수 있으며, 지역적으로 근접한 나라들 사이에서 환율변동성 전이현상이 일어난다고 주장하는 선행연구들과는 배치된다고 말할 수 있다.

We investigate interconnectedness and the contagion effect of default risk in Asian sovereign CDS markets since the global financial crisis. Using dynamic conditional correlation analysis, we find that there are significant co-movements in Asian sovereign CDS markets; that such co-movements tend to be larger between developing countries than between developed and developing countries; and that in the co-movements intra-regional nature is stronger than inter-regional nature. With the Spillover Index model, we measure contagion probabilities of sovereign default risk in CDS markets of seven Asian countries and find evidence of contagion effects among six of them; Japan is the exception. In addition, we find that these six countries are affected more by cross-market spillovers than by their own-market spillovers. Furthermore, a rolling-sample analysis reveals that contagion in the Asian sovereign CDS markets expands during episodes of extreme economic and financial distress, such as the Lehman Brothers bankruptcy, the European financial crisis, and the US-credit downgrade.
