The intraday behavior of information misreaction across various categories of investors in the Taiwan options market

This study adopts a unique dataset that includes the complete history of transactions in the Taiwan options market to investigate the misreaction patterns for marketwise observations and the transactions of four different categories of investors in the high-frequency framework. Using the results from model-free tests as benchmarks, we find that model-based tests incorrectly indicate the existence of investor misreaction and show the differences of misreaction degree among investor categories. Our findings are robust to alternative observation frequencies and duration definitions.     

The determinants of interest margins and their effect on bank diversification: Evidence from Asian banks

An endogenous switching regression model is employed for this study, categorizing the banks into regimes of high and low degrees of diversification, with our results indicating that net interest margins can be less sensitive to fluctuations in bank risk factors for functionally diversified banks as compared to more specialized banks. In turn, this implies that by diversifying their income sources, these banks can reduce the shocks to net interest margins arising from idiosyncratic risk. Our results show that prior findings can hold when the banks are located in a regime with a low degree of diversification.     

Globalization,Real Output and Multiple Structural Breaks

Abstract

This paper adopts an advanced panel cointegration method which incorporates multiple structural breaks to examine the long-run relationship between real output (RGDP) and the Konjunkturforschungsstelle (KOF) index of globalization (overall and its three main sub-indices), employing annual data of G7 countries from 1970 to 2006. Our empirical findings provide strong evidence that overall globalization and its social dimension are cointegrated with RGDP, and most of the structural break points are discovered during the period of the oil crisis (the mid-1970s) and the process of European Union integration. In addition, in evaluating whether or not the structural breaks affect the RGDP through globalization, we discover that both the overall globalization index and the social globalization index have a directly positive impact on RGDP but indirectly exhibit negative impacts on real output via the channel of social globalization.     

Constructing an index for brand equity: a hospital example

If two hospitals are providing identical services in all respects, except for the brand name, why are customers willing to pay more for one hospital than the other? That is, the brand name is not just a name, but a name that contains value (brand equity). Brand equity is the value that the brand name endows to the product, such that consumers are willing to pay a premium price for products with the particular brand name. Accordingly, a company needs to manage its brand carefully so that its brand equity does not depreciate. Although measuring brand equity is important, managers have no brand equity index that is psychometrically robust and parsimonious enough for practice. Indeed, index construction is quite different from conventional scale development. Moreover, researchers might still be unaware of the potential appropriateness of formative indicators for operationalizing particular constructs. Towards this end, drawing on the brand equity literature and following the index construction procedure, this study creates a brand equity index for a hospital. The results reveal a parsimonious five-indicator brand equity index that can adequately capture the full domain of brand equity. This study also illustrates the differences between index construction and scale development.     

INTRODUCTION / THE STATUS OF WOMEN ECONOMISTS IN US UNIVERSITIES AND THE WORLD / THE STATUS OF WOMEN ECONOMISTS IN UK UNIVERSITIES / THE STATUS OF WOMEN ECONOMISTS IN CANADIAN UNIVERSITIES / THE STATUS OF WOMEN ECONOMISTS IN CHINA'S UNIVERSITIES

Abstract

These Explorations, by eight authors from Canada, China, the US, and the UK, examine the current status of women in economics (with an eye mainly toward their status in the academic branch of the profession). The four sections of the work analyze results of surveys that show the distribution of academic positions among women economists in universities in Canada, the UK, the US, and China. The work also provides a short history of the development of committees and groups interested in furthering the status of women in the economics profession and suggests ways to improve the efforts of such groups and the status of women economists.     

Gay men's identity attempt pathway and its implication on consumption

This paper integrates sociological and psychological perspectives to examine gay consumption practices in relation to the dynamics of gay identity development. Specifically, this paper investigates how internal motivational factors underlying gay identity formation and external social influence work in concert to affect gay identity attempts throughout the gay identity development process. The findings of this study reveal that the consumption patterns of gay men are continuously evolving and correspond to attempts at discovering, disclosing, constructing, maintaining, (re)constructing, suppressing, and/or disposing the gay social identity. Precipitated by individual differences, two divergent pathways—the linear progression and pendular progression pathways—of identity attempts emerged from the gay identity development process. The data used in this study were collected through in‐depth interviews with gay men in Taiwan, where homosexuality is traditionally stigmatized but is gradually gaining acceptance with the global emergence and spread of the gay subculture. © 2011 Wiley Periodicals, Inc.     

The impact of changes to the human resources function in Australia

With the rapid development of information technology (IT) in the late twentieth century, a 'real-time' global economy is now taking shape. The social costs of being networked in the global economy vary across nations and regions. Some report job losses and fragmented working conditions, and in general social structure is endangered. The idea of maintaining a nation's social safety net and the traditional concept of the welfare state is now challenged. In this article, we deal with three issues. First, we point out that new social risks are formed by the structural change in the labour market. Second, the interaction of the nation-state and global economy is addressed; in facing new social risks, we argue, the role of nation-state is still important. However, the traditional paradigm of the welfare state needs to be re-conceptualized. Third, with the expanding view of the welfare state, this paper examines the developments of constructive welfare policies and discusses the social transformation processes in Singapore, especially in the face of the new social risks caused by globalization.     

Expiration‐day effects on individual stocks and the overall market: Evidence from Taiwan

On expiration days of the MSCI‐TW index futures, the Taiwan spot market is associated with abnormally large volume and high index volatility, along with mild index reversal. The effects concentrate only in the last five minutes of expiration days and appear to be strengthened by the adoption a call auction closing procedure by the Taiwan Stock Exchange. Individual index stocks show high volatility and strong tendency of price reversal, with large‐ and small‐cap stocks being affected more than the medium‐sized stocks. The highest‐weighted stocks exhibit excessive volume and volatility, which is disproportionate to the impact on all other index stocks, indicating that the expiration‐day effects may have been amplified by the attempt of price manipulation using large‐cap stocks. © 2009 Wiley Periodicals, Inc.

Price discovery in the options markets: An application of put‐call parity

This study investigates the relative rate of price discovery in Taiwan between index futures and index options, proposing a put‐call parity (PCP) approach to recover the spot index embedded in the options premiums. The PCP approach offers the benefits of reducing model risk and alleviating the burden of volatility estimation. Consistent with the trading‐cost hypothesis, a dominant tendency is found for futures and a subordinate but non‐trivial price discovery from options. The relative weight of options price discovery is sensitive to the methodology employed as the means of inferring the option‐implicit spot price. The empirical evidence suggests that the information contained in the PCP‐implied spot encompasses that provided by the Black‐Scholes‐implied spot. © 2008 Wiley Periodicals, Inc.

Managers,Workers, and Authority

In this paper, I examine the case made by Christopher McMahon for managerial democracy. Specifically, I examine the extent to which McMahon’s account is able to address a series of objections against the case for managerial democracy as articulated by Thomas Christiano. Christiano articulates two sets of objections. First, Christiano argues that McMahon does not succeed in ruling out the possibility that managerial authority is best understood as promissory in its basis, in which case there is no presumption in favor of its democratic exercise. Second, Christiano raises a series of objections to the effect that even if we accept McMahon’s account of the nature of managerial authority, the conclusion for the democratic exercise of that authority by workers at the level of individual economic enterprises does not follow. In the end, I argue that McMahon’s account contains the resources to address these objections if one adopts a specific view about the moral limits to relationships that involve the submission of the will on the part of one person to another. Adoption of this view, however, appears to come at the expense of what I take to be the account’s commitment to liberalism. As such, what I understand this paper to reflect more generally is the apparent difficulty for liberals in arguing that there is something inherently morally troubling about capitalist work relations.
