The impact of liquidity on option prices

This study illustrates the impact of both spot and option liquidity levels on option prices. Using implied volatility to measure the option price structure, our empirical results reveal that even after controlling for the systematic risk of Duan and Wei ( 2009 ), a clear link remains between option prices and liquidity; with a reduction (increase) in spot (option) liquidity, there is a corresponding increase in the level of the implied volatility curve. The former is consistent with the explanation on hedging costs provided by Cetin, Jarrow, Protter, and Warachka ( 2006 ), whereas the latter is consistent with the “illiquidity premium” hypothesis of Amihud and Mendelson ( 1986a ). This study also shows that the slope of the implied volatility curve can be partially explained by option liquidity. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark     

A Forward Monte Carlo Method for American Options Pricing

This study proposes a forward Monte Carlo method for the pricing of American options. The main advantage of this method is that it does not use backward induction as required by other methods. Instead, the proposed approach relies on a wise determination about whether a simulated stock price has entered the exercise region. The validity of the proposed method is supported by the mathematical proofs for the vanilla cases. With some adaption, it is shown that this forward method can be extended to price other American style options such as chooser and exchange options. This study demonstrates the effectiveness of the proposed approach using a series of numerical examples, revealing significant improvements in numerical efficiency and accuracy in contrast with the standard regression‐based method of Longstaff and Schwartz (2001). © 2012 Wiley Periodicals, Inc.

Founding scale and survival: double-edged effects of corporate sponsorship

This study examines the effects of founding scale on survival rates across independent and corporate-sponsored Taiwan securities firms. Empirical results confirm the positive effects of founding scale and corporate sponsorship on new venture survival. Results also indicate that when founding scale is large, corporate-sponsored new ventures have higher survival rates than independent ventures. However, when founding scale is smaller, the reverse is true: corporate-sponsored new ventures have lower survival rates than independent ventures. Therefore, corporate sponsorship comes off as a double-edged sword; new ventures may benefit from the parent's existent resources and social linkages, but also suffer from a loss of autonomy and control over major decisions.     

The Role of Schedule Mismatch in Ending Inventory Decisions in the Presence of Price Cuts

In the high‐tech sector, component suppliers are often able to offer preannounced price cuts (price markdowns) to manufacturers due to technological innovation that allows them to produce the existing components at lower costs. In this context, manufacturers (buyers) are primarily concerned with their existing inventory carried beyond the price cuts in order to lower inventory costs. In this research, we develop a newsvendor‐based decision model for this problem based on our experience in industry and a focal case study environment. Specifically, we consider the issue of delivery and demand uncertainties, and the interplay of the buying firm's operating hours and the transportation carrier's delivery hours, which combine to influence inventory costs and order fulfillment. We illustrate the results with numerical examples and sensitivity analyses, using a real world data set. We found that stockout cost plays a critical role in the ending inventory decisions. Lowering stockout cost will benefit buyers from lower risk of obsolescence costs.     

Manufacturers’ reliance on channel intermediaries: Value drivers in the presence of a direct web channel

Channel intermediaries constitute a key marketing asset, enabling manufacturers to reach out to and serve end-users or customers. The manufacturer-intermediary relationship has to create value for and deliver it to the end-user. In this process manufacturers and intermediaries add value to each other. Drawing upon the Governance Value Analysis (GVA) framework, this paper focuses on the manufacturer's perspective of value contributed by themselves and their intermediaries. The research setting is a multi-channel context where the manufacturer employs a direct web site for marketing in addition to the intermediary channel. We find that relational investments in intangible assets such as training and operating procedures by manufacturers in intermediaries, and intermediary investments in their end-customer relationships, increase manufacturers’ reliance on intermediaries even when the manufacturer has its own direct web site. Further, regardless of having their own website, manufacturers’ reliance on intermediaries increases with the web competence of their intermediaries. In addition, we find that, to the extent that the manufacturer's direct web site can perform the same functions as the intermediaries, manufacturer reliance on its intermediaries decreases. Surprisingly, manufacturers whose web sites have e-commerce transaction facility, rely on intermediaries more than those manufacturers whose web sites do not have this facility. Finally, the study finds that manufacturers’ reliance on intermediaries has increased over time despite their direct web channels, probably due to market growth opportunities. Overall, our study findings showcase the complementary role played by manufacturers’ web sites and intermediaries in serving their end customers in growth markets.     

The moderating role of managerial ties in market orientation and innovation: An Asian perspective

This empirical study contributes to the extant literature by investigating the relations among market orientation, managerial ties and innovation simultaneously and interactively, from an Asian perspective. Our findings reveal that customer orientation and interfunctional coordination have a positive impact on innovation. Moreover, managerial ties play a moderation role in the market orientation–innovation linkage. Business ties enhance the relation between customer orientation and interfunctional coordination and innovation. On the other hand, business ties and competitor orientation have a negative interaction effect on innovation. In addition, political ties also dampen the relation between interfunctional coordination and innovation. Such results add new insights to the extant literature and provide implications for future research and marketing practices in Asia.     

An Asymmetric Oligopolist can Improve Welfare by Raising Price

We demonstrate that, in Bertrand/Cournot equilibrium, a firm with a relatively small market share may improve social welfare by raising its price. This could be because the price increase can mitigate an output-structure distortion: if there are two goods which have the same marginal cost, then, under some conditions, the good in higher demand (the efficient good) will have a higher markup rate than the other good (the inefficient good). This suggests that the output structure is distorted in favor of the inefficient good, since the higher markup rate of the efficient good should lead to a considerable increase in demand for the inefficient good.     

Buyers-to-shoppers ratio of shopping malls: A probit study in Hong Kong

Buyers-to-shoppers ratio (i.e. conversion rate) has long been one of the commonly adopted metrics in assessing retail performance of shopping malls, but it is almost always relied on interviews, consumer surveys, and questionnaires. These methods are intrinsically problematic in ascertaining the trustworthiness of the responses. This paper is probably the first objective study on the buyers-to-shoppers ratio based on actual observations in shopping malls in Hong Kong. A probit model is used to study factors affecting the ratio. The results show that consumer-surveys seriously over-estimate the ratio.     

Generalised Geske--Johnson Interpolation of Option Prices

Abstract:  This paper describes four separate option types as special cases of Bermudans with general inter–exercise and time to final maturity. This produces a surface with European, finite American, infinite Bermudan and infinite American options as special cases. This allows Geske–Johnson (1984) two–point pricing to be extended to consider time–to–maturity as well as time–between–exercise opportunities. Due to their position on this 'map', infinite Bermudans are christened Arctic options and their pricing solution is presented. Numerical comparisons to benchmark methods are made for call prices under GBM although the results here hold for other processes and for both puts and calls when symmetry arguments are invoked.
