This paper studies the price‐setting problem of market makers under risk neutrality and perfect competition in continuous time. The classic approach of Glosten–Milgrom is followed. Bid and ask prices are defined as conditional expectations of a true value of the asset given the market makers' partial information that includes the customers' trading decisions. The true value is modeled as a Markov process that can be observed by the customers with some noise at Poisson times. A mathematically rigorous analysis of the price‐setting problem is carried out, solving a filtering problem with endogenous filtration that depends on the bid and ask price processes quoted by the market maker. The existence and uniqueness of the bid and ask price processes is shown under some conditions.  相似文献

We study behavior in the race game with the aim of assessing whether teams can create synergies. The race game has the advantage that the optimal strategy depends neither on beliefs about other players nor on distributional or efficiency concerns. Our results reveal that teams not only outperform individuals but that they can also beat the “truth-wins” benchmark. In particular, varying the length of the race game we find that the team advantage increases with the complexity of the game.  相似文献

We study the merits of capped retirement products with guarantee for investors who have the flexibility to dynamically adjust their investment strategy. All contracts under consideration are fairly priced such that the net profit of the provider is zero. Without the rider, an expected utility maximizing CRRA investor does not want an investment cap. Here, she commits herself to a strategy a priori. With the flexibility rider, the optimization problem changes and the optimal strategy is a response to an exogenously set price. A fair pricing then anticipates the optimal response of the investor. We show that the maximum expected utility of the investor can, for anticipated fairly priced products, be obtained for a finite cap. Thus, a capped product design can give a Pareto improvement to the otherwise uncapped contract version.  相似文献

Artificial intelligence is revolutionizing the way we do business. Whereas both the adoption of technological innovations and strategic decision making have been subject to prior research, this experimental study is first to combine both. To understand the impact of choice complexity and cognitive perceptions on the willingness to delegate a strategic decision to an algorithm, we conducted an experiment with 310 participants. We find that although choice complexity has no effect, participants with low levels of situational awareness are more likely to delegate. The findings augment research on choice complexity in decision making by emphasizing the relevance of cognitive perceptions.  相似文献

Clean‐tech innovations are an important driver in solving global issues such as climate change and for the sustainable development of economies around the world. Whereas a large part of the literature focuses on clean‐tech ventures, less is known on corporate entrepreneurship, that is, entrepreneurial behavior in established firms and its relation to sustainability. This paper extends the sustainable entrepreneurship debate to corporate entrepreneurship, which represents a fruitful avenue to further developing clean technologies. We focus particularly on clean‐tech firms' organizational preparedness for corporate entrepreneurship (OPCE), that is, how well a firm's structures and processes are set for entrepreneurial activities. On the basis of contingency theory, this study investigates how the level of OPCE influences the environmental and financial performance of clean‐tech firms and whether their environmental orientation affects these relationships. Building on data from 103 firms, we find support for a positive effect of OPCE on both environmental and financial performance. Both effects are stronger the higher the external environmental orientation. In contrast, the leverage of internal environmental orientation is not equally positive. Our study reveals that the effect of OPCE on financial performance diminishes for firms that are more strongly driven by an internal than an external environmental orientation.  相似文献

Demographic change raises demand for non‐tradable old‐age related services relative to tradable commodities. This demand shift increases the relative price of non‐tradables and thereby causes real exchange rates to appreciate. We claim that the change in demand affects prices via imperfect intersectoral factor mobility. Using a sample of 15 OECD countries, we estimate a robust increase of relative prices. According to our main estimate, up to one fifth of the average increase in relative prices between 1970 and 2009 can be attributed to population ageing. Further findings confirm the relevance of imperfect factor mobility: Countries with more rigid labour markets experience stronger price effects.  相似文献
