Outperformance portfolio optimization via the equivalence of pure and randomized hypothesis testing

We study the portfolio optimization problem of maximizing the outperformance probability over a random benchmark through dynamic trading with a fixed initial capital. Under a general incomplete market framework, this stochastic control problem can be formulated as a composite pure hypothesis testing problem. We analyze the connection between this pure testing problem and its randomized counterpart, and from the latter we derive a dual representation for the maximal outperformance probability. Moreover, in a complete market setting, we provide a closed-form solution to the problem of beating a leveraged exchange traded fund. For a general benchmark under an incomplete stochastic factor model, we provide the Hamilton–Jacobi–Bellman PDE characterization for the maximal outperformance probability.     

Ethics Education in the Australian Accounting Curriculum: A Longitudinal Study Examining Barriers and Enablers

Abstract

The increasing significance of ethics in the accounting profession is evidenced by the seminal events that witnessed the collapse of major corporations (e.g. Enron and WorldCom); regulatory interventions (e.g. Sarbanes-Oxley Act in the USA and the CLERP 9 Act in Australia); and calls for increased ethics interventions in the accounting curriculum. This project has two objectives: to investigate the nature of ethics education in the Australian accounting curriculum and how it has changed from 2000 to 2012; and to analyse the barriers to enhancing ethics education by soliciting the opinions of Heads of Departments/Schools of Australian universities. Compared with early empirical evidence, universities responded to the call for ethics education with increased levels of ethics intervention, but had failed to enhance the extent of ethics education coverage in the intervening period in which the data were collected. The lack of qualified staff and research opportunities represent major obstacles to the enhancement of ethics education.     

The duration of international joint ventures an foreign wholly-owned subsidiaries

An international joint venture is formed when the partners contribute different benefits to the venture. Each party learns from the others through the joint venture. However, the literature suggests that joint ventures are unstable. So it is hypothesized that, on average, an international joint venture will have a shorter duration than a foreign wholly-owned subsidiary. Data on US foreign direct investment (FDI) abroad and FDI in the United States are applied to test the instability of joint ventures. The proportional hazards model is applied while exponential distribution and Weibull distribution are used to cross-check the results. On the whole, the results are consistent with the hypothesis. In particular, the two types of US affiliates are significantly different in duration although the support for the hypothesis from FDI in the United States is weak.     

Macroeconomics and housing: a review of the literature

There is a relatively recent, growing recognition about the importance of the interactive nexus between and among housing markets and the macroeconomy. This paper provides a selective survey of the small but nascent research efforts focused upon interplay between the housing markets and macroeconomy. The discussion examines these lynchpin housing–macroeconomic nexus issues pertaining to housing taxation, housing cycles, and housing market–urban structural form.     

The choice between an international joint venture and a wholly-owned subsidiary in a developing country under technology spillover effects

A general equilibriumm model of a foreign multinational enterprise's decisions on establishing a wholly-owned subsidiary or forming a joint venture is built on firm-specific knowledge and plant-specific knowledge when there are intraindustry and interindustry technology spillovers. The welfare effects of a host developing country under closed economies, unrestricted foreign direct investment, and the policy of minimum local ownership requirements are compared. A developing country's worry is confirmed: Introduction of competition from foreign firms may not improve the welfare of the host country. However, the minimum local ownership requirement is Pareto-superior to a closed economy.     

Explaining country and cross‐border liquidity commonality in international equity markets

Using a large cross section of intraday data from 25 developed countries, we study commonality in liquidity, both within and across international equity markets, over 15‐minute intervals. Within‐country and cross‐border liquidity commonalities are found to be significant and, after controlling for country and industry effects, relate to such firm‐specific measures as size, bid–ask spread, and the extent of analyst coverage. Additionally, within‐country liquidity commonality is lower for firms with depository receipts cross listed in New York or London. Cross‐border liquidity commonality is particularly high for firms with relatively high actual ownership by foreign institutions. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 29:630–652, 2009     

A Dualistic Model of Harmony and its Implications for Conflict Management in Asia

Conflict avoidance is common in East Asia, and the Confucian notion of harmony is often invoked to explain this tendency. We review the classical Confucian doctrines and found no encouragement of conflict avoidance in Confucian teachings. Quite the contrary, the Confucian notion of harmony embodies disagreement and open debates. Thus, we argue that harmony as conflict avoidance is not a main feature of classical Confucianism, but a characteristic of the secular version that is associated with cultural collectivism. We then review several theories that are based on the notion of harmony, and show that they are compatible with a dualistic model of harmony, which posits an instrumental as well as a value motive in harmony-seeking behavior. In the instrumental perspective, harmony is viewed as a means to a typically materialistic end, whereas in the value perspective, harmony is deemed an end in its own right. Conflict avoidance is primarily driven by the instrumental motive. These two motives are then crossed to form four types of harmony-seeking behaviors. This typology is discussed in terms of its implications for future research and its applications in conflict management.     

All‐units discounts as a partial foreclosure device

We investigate the strategic effects of all‐units discounts (AUDs) used by a dominant firm in the presence of a capacity‐constrained rival. Due to the limited capacity of the rival, the dominant firm has a captive portion of the buyer's demand for the single product. As compared to linear pricing, the dominant firm can use AUDs to go beyond its captive portion by tying its captive demand with part of the competitive demand and partially foreclose its small rival. When the rival's capacity level is well below relevant demand, AUDs reduce the buyer's surplus.     

Real options game models of R&D competition between asymmetric firms with spillovers

Using real options game models, we consider the characterization of strategic equilibria associated with an asymmetric Research and Development (R&D) race between an incumbent firm and an entrant firm in the development of a new innovative product under market and technological uncertainties. The random arrival time of the discovery of the patent protected innovative product is modeled as a Poisson process. Input spillovers on the R&D effort are modeled by the change in the leader’s hazard rate of success of innovation upon the follower’s entry into the R&D race. Asymmetry between the two competing firms include sunk costs of investment, stochastic revenue flow rates generated from the product, and hazard rates of arrival of success of R&D efforts of the two firms. Under asymmetric duopoly, we obtain the complete characterization of the three types of Markov perfect equilibria (sequential leader–follower, preemption and simultaneous entry) of the firms’ optimal R&D entry decisions with respect to various sets of model parameters. Our model shows that under positive input spillover, preemptive equilibrium does not occur in the R&D race due to the presence of dominant second mover advantage. The two firms choose optimally to enter simultaneously if the sunk cost asymmetry is relatively small; otherwise, sequential equilibrium would occur. When the initial hazard rate is low relative to the level of input spillover, simultaneous entry would occur as an optimal decision, signifying another scenario of dominant second mover advantage. On the other hand, when the initial hazard rate is sufficiently high so that the first mover advantage becomes more significant, simultaneous equilibrium does not occur even under high level of positive input spillover.     

The link between institutions, technical change and macroeconomic volatility

This paper evaluates the role of technical change as a mediating channel through which the effects of institutions trickle down to affect growth volatility. Using different samples, estimation procedures and indicators of institutions and technical change, the results show that technical change is an important stabilizing force of growth volatility and that at least part of the stabilizing force of technical change originates from strong institutions. This conclusion does not appear to be generated by weak data, simultaneity bias or measurement errors and is remarkably robust to a large number of alternative specifications.
