Classical put–call symmetry relates the price of puts and calls under a suitable dual market transform. One well‐known application is the semistatic hedging of path‐dependent barrier options with European options. This, however, in its classical form requires the price process to observe rather stringent and unrealistic symmetry properties. In this paper, we develop a general self‐duality theorem to develop valuation schemes for barrier options in stochastic volatility models with correlation. 相似文献

New knowledge presents opportunities for commercial value and can hence be a critical asset for entrepreneurial ecosystems (EEs). In particular, general purpose technologies are major drivers of entrepreneurship. Thus, a nuanced understanding on technological knowledge and its spillovers among actors within an EE is warranted. Using knowledge‐spillover‐based strategic entrepreneurship theory, we propose to observe knowledge spillovers through the assessment of the knowledge bases of a technology in an EE. To do so, this article proposes to use three key sources of knowledge: publications reflecting the emerging knowledge base, patents representing the realized knowledge base, and startups showing the experimental knowledge base. This article uses secondary data sources such as Web of Science and applies the method of bibliometrics to illustrate how an assessment is carried out in practice by evaluating the artificial intelligence (AI) knowledge bases in Sydney from 2000 to 2018. The findings are summarized with an illustration of the evolution of the key actors and their activities over time in order to indicate the key strengths and weaknesses in Sydney's AI knowledge among the different bases. Contrary to expectations from the high potential of knowledge spillovers from a general purpose digital technology such as AI, the article shows that apparent knowledge spillovers are yet highly limited in Sydney. Even though Sydney has a strong emerging knowledge base, the realized knowledge base seems weak and the experimental knowledge base is slowly improving. That observation itself verifies the need to take strategic actions to facilitate knowledge spillovers within EEs. After the implications for theory and policy makers are discussed, suggestions for further studies are proposed. 相似文献

The odious debt problem refers to a government's ability to borrow for elite consumption while the general population repays. Although an intuitive response is to ban lending to such regimes, this paper shows that if a government faces endogenous replacement risk, then an international odious debt doctrine which (i) decreases the country's debt ceiling; (ii) decreases the likelihood that the citizens must repay the debt; or (iii) increases the government's cost of borrowing for a given default risk can all decrease citizens' welfare. These findings suggest that, even when a regime is clearly odious, allowing it to borrow up to a point may be preferable to a complete lending ban. 相似文献

Economic, Demographic, and Institutional Determinants of Life Insurance Consumption across Countries 总被引:8,自引:0,他引:8
Life insurance has become an increasingly important part ofthe financial sector over the past 40 years, providing a rangeof financial services for consumers and becoming a major sourceof investment in the capital market. But what drives the largevariation in life insurance consumption across countries remainsunclear. Using a panel with data aggregated at different frequenciesfor 68 economies in 19612000, this article finds thateconomic indicatorssuch as inflation, income per capita,and banking sector developmentand religious and institutionalindicators are the most robust predictors of the use of lifeinsurance. Education, life expectancy, the young dependencyratio, and the size of the social security system appear tohave no robust association with life insurance consumption.The results highlight the importance of price stability andbanking sector development in fully realizing the savings andinvestment functions of life insurance in an economy. 相似文献

Political risk represents an important hidden transaction cost that reduces international trade. This paper investigates the claim that public export credit guarantees mitigate this friction to trade flows and hence promote exports. We employ an empirical trade gravity model, where we explicitly control for political risk in the importing country in order to evaluate the effect of export guarantees. Using a novel data set on guarantees, we estimate the effect of guarantees in a static and dynamic panel model. We find a statistically and economically significant positive effect of public export guarantees on exports which indicates that export promotion is indeed effective. Furthermore, political risk turns out to be an important obstacle for exports and hence should be taken into account in any empirical model of trade. 相似文献

Using a firm-level survey database covering 48 countries, we investigate how financial and institutional development affects financing of large and small firms. Our database is not limited to large firms but includes small and medium-size firms and data on a broad spectrum of financing sources, including leasing, supplier, development, and informal finance. Small firms and firms in countries with poor institutions use less external finance, especially bank finance. Protection of property rights increases external financing of small firms significantly more than of large firms, mainly due to its effect on bank finance. Small firms do not use disproportionately more leasing or trade finance compared with larger firms, so these financing sources do not compensate for lower access to bank financing of small firms. We also find that larger firms more easily expand external financing when they are constrained than small firms. Finally, we find suggestive evidence that the pecking order holds across countries. 相似文献

This paper presents a new empirical approach to address the problem of trading time differences between markets in studies of financial contagion. In contrast to end‐of‐business‐day data common to most contagion studies, we employ price observations, which are exactly aligned in time to correct for time‐zone and end‐of‐business‐day differences between markets. Additionally, we allow for time lags between price observations in order to test the assumption that the shock is not immediately transmitted from one market to the other. Our analysis of the financial turmoil surrounding the Asian crisis reveals that such corrections have an important bearing on the evidence for contagion, independent of the methodology employed. Using a correlation‐based test, we find more contagion the faster we assume the shock to be transmitted. 相似文献

Can economic bonus programs jeopardize service relationships? 总被引:1,自引:0,他引:1
Research findings on the impact of economic bonus programs on service relationships are contradictory. While some studies
find positive effects of economic bonus programs on customer’s relational behavior, other studies demonstrate negative effects.
Building on self-determination theory, Dholakia (J Market Res 43(2):109–120, 2006) points at a possible explanation for these conflicting results, arguing that economic marketing programs have negative effects
on self-determined customers when the program is perceived as controlling by them. By testing the effect of four different
kinds of economic bonus programs on loyalty in an experimental setting using a nationwide representative sample of 768 participants,
this research is the first that provides empirical evidence that economic bonus programs can indeed endanger service relationships
by reducing customer’s self-determination. Implications of our findings for the abundance of economic bonus programs offered
to service customers these days are highlighted. 相似文献

We examine the relative roles of marketing actions and product quality in determining commercial success. Using the motion
picture context, in which product quality is difficult for consumers to anticipate and information on product success is available
for different points in time, we model the effects of studio actions and movie quality on a movie’s sales during different
phases of its theatrical run. For a sample of 331 recent motion pictures, structural equation modeling demonstrates that studio
actions primarily influence early box office results, whereas movie quality influences both short- and long-term theatrical
outcomes. The core results are robust across moderating conditions. We identify two data segments with follow-up latent class
regressions and explore the degree of studio actions needed to “save” movies of varying quality. We finally offer some implications
for research and management. 相似文献
