The Asia-Pacific region’s currency markets are generally efficient within-country when tested using the 30 and 31 cointegration technique whereas market efficiency fails to hold when tested using Fama’s (1984) conventional regression. Using the Pilbeam and Olmo (2011) model, we reconcile these conflicting findings. The Pilbeam and Olmo (2011) model confirms within-country market efficiency. It further confirms that free-float currency markets are more resilient than managed-float currency markets among 12 Asia-Pacific economies. From the across-country perspective, the foreign exchange markets are mostly efficient and the results show that the 1997–1998 Asian financial crisis was a more disturbing event than the 2008–2009 global financial crisis in the region. 相似文献

The Korean passenger car market is dominated by a few domestic producers. In this paper, we investigate whether this market structure is the result of import tariffs and taxes that penalize foreign manufacturers. Our counterfactual simulation under two FTA scenarios shows that the market shares of imported and domestic cars show minimal adjustments, suggesting that import tariffs and taxes may not explain the lack of penetration of import cars in Korea. We predict changes in consumer surplus and discuss the policy implications of our findings. 相似文献

An expression of the optimal expected spread between the rates of fixed and variable rate loans offered by a competitive risk-averse bank is derived. We find that the expected spread varies directly with the volatility of the funding cost, the bank's degree of risk aversion, and the competitive profit margin on variable rate loans. Our analysis also characterizes the optimal mix of fixed and variable rate lending in a bank's loan portfolio. 相似文献

Although the notion that HRM activities are necessary conditions for achieving certain outcomes is widespread in HRM research, most empirical studies follow an additive sufficiency logic. That is, they analyse whether HRM activities increase an outcome, assuming that they can compensate for one another. However, this does not correspond to the idea of necessity where single HRM activities are required for an outcome to occur and cannot be compensated when absent. We discuss the differences between sufficiency and necessity logics in terms of theory, methodology, and practical relevance. Also, we suggest using a new approach and analysis technique in HRM research: necessary condition analysis. We illustrate the application of the method by analysing data on the relationship between ability‐, motivation‐, and opportunity‐enhancing HRM practices (i.e., high‐performance work practices) and employee performance. This illustrative example highlights that necessary conditions require particular theoretical attention and suitable empirical methods. The paper concludes by showing the value of studying necessary conditions, because such analyses allow straightforward recommendations to be given of high relevance for HRM practice, which differ from and add to recommendations based on additive sufficiency logic and analyses. 相似文献

We decompose the recent patent increase into components representing (1) an increase in resources made available to research and development, (2) an across-the-board rise in the patent yield of an R&D dollar, and (3) changes in the patent yield in individual industries. Two high tech fields, computer hardware and pharmaceuticals, account for 22 percent of the patent increase. While these two industries had the fastest R&D growth among the industries we study, the pharmaceutical industry experienced a decline in its patent yield, limiting its patent growth. We show that increased R&D spending accounts for 70 percent of the patent increase. We discuss our results in the context of alternative hypotheses of the patent surge. We also compare our results to the anecdotal evidence of firm R&D performance at the industry level. 相似文献

In 1997, the SEC implemented the new order handling rules (OHRs) on the NASDAQ. We observe that some uncompetitive positions gained market share without improving quote competitiveness after the implementation of the OHRs. Also observed is a significant decline in the sensitivity of trading volume to quote competitiveness, indicating lower incentive for NASDAQ dealers to engage in quote competition in the post‐OHR regime. We find that positions that gained trading volume without improving quote competitiveness were less competitive and were more closely associated with stocks showing low information asymmetry, which suggests that preferenced trading might be responsible for the decline in the trading volume sensitivity. Examining entries and exits around the periods of adopting OHRs, we observe net entry of uncompetitive positions and net exit of competitive positions, which indicates that preferenced trading crowded out quote competition subsequent to the OHRs. Our findings suggest that forcing intense quote competition alone produced an unwanted effect that preferencing emerged as a more attractive alternative to quote competition. 相似文献

Previous research describes two key ways in which a new product may encroach on an existing market. In high‐end encroachment, the new product first sells to high‐end customers and then diffuses down‐market; in low‐end encroachment, the new product enters at the low end and encroaches up‐market. This paper focuses on high‐end encroachment, which can further be broken down into three subtypes, which are called the immediate, the new‐attribute, and the new‐market forms of high‐end encroachment. This paper makes three key contributions. First, it provides a sound theoretical underpinning for the three distinct subtypes of high‐end encroachment—a linear reservation price curve model (LRPCM) is used to establish this theoretical foundation. Second, this paper delineates and illustrates four different ways the high‐end new‐market diffusion process may progress over time. These four are: (1) the traditional type, where the new product diffuses relatively slowly and methodically over time; (2) the fad scenario, where the new product opens a new market but then fizzles out after a relatively short period of high sales; (3) the rapid diffusion outcome, where the new product opens a new market and then rapidly diffuses down‐market; and (4) the prolonged‐niche type, where the new product purposefully restricts itself to its own niche rather than diffusing down‐market. The third key contribution of this paper is to offer managerial insights into the new‐market high‐end encroachment process by discussing two short case studies; namely, a retrospective look at the introduction of the iPhone, and a prospective look at Tesla's challenges in growing the market for its electric car. With regard to the iPhone, it helps explain why Apple precipitously dropped the price of the iPhone by one third only 68 days after its introduction. With regard to Tesla, it discusses how Tesla must leverage the revenues that stem from its current high‐end pricing power. Tesla must be able to progress down the learning curve fast enough so that it can create a virtuous cycle; a cycle in which cost reductions and technology improvements lead to price reductions and increased sales, which in turn lead to further cost reductions. At the conclusion of the paper, a step‐by‐step approach is offered to aid in determining which type of encroachment should be pursued and in determining how the encroachment pattern will eventually develop. The encroachment framework and the step‐by‐step approach are intended to help managers better assess and mitigate the risks inherent with a new product introduction. 相似文献

We study optimal monetary policy for a small open economy in a model where both inflation and output show persistence. We incorporate habit formation into intertemporal consumption decision and modify the Calvo price setting to include indexation to past inflation. The message conveyed from this study can be viewed as twofold. First, full stabilization of domestic prices or the output gap is not optimal policy. This is because stabilization of the output gap leads to serial correlation in domestic inflation, whereas under full stabilization of domestic prices the output gap displays some serial correlation. It is, however, shown that at the zero inflation steady state, stabilizing domestic prices is equivalent to stabilizing the output gap. Second, in the presence of foreign income shock inflation and the output gap are more stable under flexible CPI inflation targeting than under other alternative policy regimes considered. 相似文献

Studies on the influence of ambiguity on innovation show inconsistent understandings: it could be beneficial owing to flexibility, while it might be detrimental owing to distraction of information. Faced with the contradictory understandings, this study examines whether technological standardisation and industry classification could increase innovations of an industry. Using ISO9001 and the SIC codes in Korea from 1998 to 2010, the empirical tests illustrate inverted U-shaped relationships between industry-level innovation and standardisation/classification. Therefore, it is suggested that a moderate degree of standardisation and classification provides a positive infrastructure for innovation by providing the necessary guidelines for a firm's behaviour as well as maintaining its flexibility. 相似文献

This paper investigates the optimal retirement of an individual in the presence of involuntary unemployment risks and borrowing constraints in a complete market with frictions. We use an intensity model and loading factors to illustrate the involuntary unemployment risks and frictions in unemployment insurance markets. Using reasonably calibrated parameters, we observe that high involuntary unemployment intensity and loading factors could be important explanations for the empirical findings emphasized in recent studies. We also find that an individual with high leisure demand after retirement reduces consumption during retirement and increases stockholdings as retirement time approaches. 相似文献
